Beneficial acute effects of resistance exercise on cognitive functions may be modified by exercise intensity or by habitual physical activity. Twenty-six participants (9 female and 17 male; 25.5 ± 3.4 years) completed four resistance exercise interventions in a randomized order on separate days (≥48 h washout). The intensities were set at 60%, 75%, and 90% of the one repetition maximum (1RM). Three interventions had matched workloads (equal resistance*nrepetitions). One intervention applied 75% of the 1RM and a 50% reduced workload (resistance*nrepetitions = 50%). Cognitive attention (Trail Making Test A—TMTA), task switching (Trail Making Test B—TMTB), and working memory (Digit Reading Spans Backward) were assessed before and immediately after exercise. Habitual activity was assessed as MET hours per week using the International Physical Activity Questionnaire. TMTB time to completion was significantly shorter after exercise with an intensity of 60% 1RM and 75% 1RM and 100% workload. Friedman test indicated a significant effect of exercise intensity in favor of 60% 1RM. TMTA performance was significantly shorter after exercise with an intensity of 60% 1RM, 90% 1RM, and 75% 1RM (50% workload). Habitual activity with vigorous intensity correlated positively with the baseline TMTB and Digit Span Forward performance but not with pre- to post-intervention changes. Task switching, based on working memory, mental flexibility, and inhibition, was beneficially influenced by acute exercise with moderate intensity whereas attention performance was increased after exercise with moderate and vigorous intensity. The effect of regular activity had no impact on acute exercise effects.
The relationship between exhaustion and work engagement has received considerable attention during the past decades. Although the theoretical proposition exists that work engagement may increase exhaustion over time, previous research has been mixed. Drawing on the transactional stress model and applying latent growth modeling, we aim to provide a more comprehensive picture of the work engagement–exhaustion relationship over time. In two longitudinal studies, with four measurement points each, we found consistent evidence that a higher initial work engagement related to increased exhaustion over time. Consistent with our hypotheses, a higher initial work engagement also related to less initial exhaustion, and increases in work engagement related to decreases in exhaustion over time. However, contrary to our expectations, a higher initial exhaustion related to elevated work engagement over time. In conclusion, our findings suggest that engaged employees are less exhausted but face a higher risk of exhaustion over time. At the same time, exhausted employees are less engaged, but they have the potential to become more so over time. The theoretical and practical implications of these findings will be discussed in this paper.
Background: Visual exploration in autism spectrum disorder (ASD) is characterized by attenuated social attention. The underlying oculomotor function during visual exploration is understudied, whereas oculomotor function during restricted viewing suggested saccade dysmetria in ASD by altered pontocerebellar motor modulation. Methods: Oculomotor function was recorded using remote eye tracking in 142 ASD participants and 142 matched neurotypical controls during free viewing of naturalistic videos with and without human content. The sample was heterogenous concerning age (6–30 years), cognitive ability (60–140 IQ), and male/female ratio (3:1). Oculomotor function was defined as saccade, fixation, and pupil-dilation features that were compared between groups in linear mixed models. Oculomotor function was investigated as ASD classifier and features were correlated with clinical measures. Results: We observed decreased saccade duration (∆M = −0.50, CI [−0.21, −0.78]) and amplitude (∆M = −0.42, CI [−0.12, −0.72]), which was independent of human video content. We observed null findings concerning fixation and pupil-dilation features (POWER = .81). Oculomotor function is a valid ASD classifier comparable to social attention concerning discriminative power. Within ASD, saccade features correlated with measures of restricted and repetitive behavior. Conclusions: We conclude saccade dysmetria as ASD oculomotor phenotype relevant to visual exploration. Decreased saccade amplitude and duration indicate spatially clustered fixations that attenuate visual exploration and emphasize endogenous over exogenous attention. We propose altered pontocerebellar motor modulation as underlying mechanism that contributes to atypical (oculo-)motor coordination and attention function in ASD.
Development and preliminary validation of the Emotions while Learning an Instrument Scale (ELIS)
(2021)
Learning to play a musical instrument is associated with different, partially conflicting emotions. This paper describes the development and psychometric properties of the Emotions while Learning an Instrument Scale (ELIS). In a longitudinal study with 545 German elementary school children factorial structure and psychometric properties were evaluated. Exploratory and confirmatory factor analyses confirmed a two-factor solution measuring Positive musical Emotions while Learning an Instrument (PELI) and Negative Emotions while Learning an Instrument (NELI). Both subscales yielded scores with adequate internal reliability (Cronbach’s α = .74, .86) and relatively stable retest reliabilities over 18 months (r = .11 -.56). Preliminary evidence of congruent and divergent validity of the subscales is provided. Implications for future research of musical emotional experiences in children are discussed.
Background: Associations between age, concerns or history of falling, and various gait parameters are evident. Limited research, however, exists on how such variables moderate the age-related decline in gait characteristics. The purpose of the present study was to investigate the moderating effects of concerns of falling (formerly referred to as fear of falling), history of falls & diseases, and sociodemographic characteristics on changes in gait characteristics with increasing age in the elderly. Methods: In this individual participant level data re-analysis, data from 198 participants (n = 125 females) from 60 to 94 years of age were analysed (mean 73.9, standard deviation 7.7 years). Dependent variables were major spatiotemporal gait characteristics, assessed using a capacitive force measurement platform (zebris FDM-T). Age (independent variable) and the moderating variables concerns of falling (FES-I), gender/sex, history of falls and fall-related medical records, number of drugs daily taken, and body mass index were used in the statistical analysis. Hierarchical linear mixed moderation models (multilevel analysis) with stepwise (forward) modelling were performed. Results: Decreases of gait speed (estimate = −.03, equals a decrease of 0.03 m/s per year of ageing), absolute (− 1.4) and gait speed-normalized (−.52) stride length, step width (−.08), as well as increases in speed normalized cadence (.65) and gait speed variability (.15) are all age-related (each p < .05). Overall and specific situation-related concerns of falling (estimates: −.0012 to −.07) were significant moderators. History of potentially gait- and/or falls-affecting diseases accelerated the age-related decline in gait speed (−.002) and its variability (.03). History of falls was, although non-significant, a relevant moderator (in view of increasing the model fit) for cadence (.058) and gait speed (−.0027). Sociodemographics and anthropometrics showed further moderating effects (sex moderated the ageing effect on stride length, .08; height moderated the effect on the normalised stride length, .26; BMI moderated the effects on step width, .003). Conclusion: Age-related decline in spatiotemporal gait characteristics is moderated by concerns of falling, (non-significantly) by history of falls, significantly by history of diseases, and sociodemographic characteristics in 60–94 years old adults. Knowing the interactive contributions to gait impairments could be helpful for tailoring interventions for the prevention of falls. Trial registration: Re-analysis of [21–24].
Die vorliegende Arbeit beschäftigt sich mit der außerhäuslichen Alltagsmobilität älterer Menschen, die eine zentrale Schlüsselfunktion in der Erhaltung von Lebensqualität und Gesundheit besonders im höheren Lebensalter einnimmt. Außerhäusliche Alltagsmobilität vollzieht sich stets in einem räumlichen Umweltausschnitt und kann aus ökogerontologischer Perspektive als Ergebnis eines gelungenen Person-Umwelt-Austauschs verstanden werden. Inwiefern psychologische Ressourcen im Sinne mobilitätsspezifischer Einstellungen zum Verständnis von zielgerichteter und habitualisierter Alltagsmobilität älterer Menschen beitragen können, ist Gegenstand der vorliegenden Arbeit. Altersspezifische, mobilitätsrelevante Einstellungen im außerhäuslichen Kontext werden sowohl in der sozialwissenschaftlichen Mobilitäts- und Alternsforschung als auch in der Praxis, etwa im Rahmen einer altersgerechten Stadtgestaltung, bislang noch zu wenig berücksichtigt. Die vorliegende Arbeit reagiert auf dieses Forschungsdesiderat, indem sie mobilitätsspezifische Einstellungen im höheren Lebensalter konzeptuell beschreibt, in den Kontext ökogerontologischer Theorien einbettet und ihre Bedeutung für den Erhalt eines aktiven und gelingenden Alterns untersucht. Im Rahmen der Dissertation wurde zunächst auf der Basis klassischer und neuer ökogerontologischer Modelle das Konstrukt der mobilitätsbezogenen Handlungsflexibilität und Routinen (MBFR) konzeptuell entwickelt. MBFR umfasst einerseits die individuelle Überzeugung, das eigene Mobilitätsverhalten an Herausforderungen außer Haus anpassen zu können (FLEX) und andererseits die Präferenz für mobilitätsbezogene Alltagsroutinen (ROU). Daraufhin wurde ein standardisiertes Messinstrument zur Erfassung des MBFR-Konzepts entwickelt, optimiert und hinsichtlich seiner psychometrischen Qualität untersucht. Die Formulierung der Testitems erfolgte in Anlehnung an bereits existierende Fragebögen zu verwandten Konstrukten. In der vorwiegend online durchgeführten Pilotstudie (Penger & Oswald, 2017) wurden die Items mittels explorativer Faktorenanalysen hinsichtlich ihrer dimensionalen Struktur untersucht. Die Stichprobe umfasste 265 Personen im Alter von 65 Jahren oder älter. Die Analysen des MBFR-Instruments ergaben nach Ausschluss von Items mit niedrigen und nicht eindeutigen Ladungen drei substanzielle Faktoren. Die Items der ersten Dimension bildeten die Überzeugung ab, flexibel mit personenbezogenen, altersassoziierten Herausforderungen (z. B. Schwierigkeiten im Gehen oder auf eine Gehhilfe angewiesen sein) umgehen zu können, um außerhäuslich mobil zu sein. Die Items der zweiten Dimension erfassten die Überzeugung, flexibel mit herausfordernden außerhäuslichen Umweltbedingungen (z. B. eine verlegte Haltestelle oder ein schlechter Zustand der Gehwege) umgehen zu können. Items, die auf den dritten Faktor luden, bildeten die Neigung zu Routinen im Mobilitätsalltag ab, z. B. bekannte Wege beizubehalten oder bei der Ausübung von außerhäuslichen Aktivitäten vertraute Orte aufzusuchen. Während die ersten beiden Faktoren mobilitätsbezogene Handlungsflexibilität (FLEX) messen, werden im dritten Faktor habitualisierte Verhaltensweisen (ROU) erfasst. Alle drei Faktoren wiesen eine akzeptable Reliabilität auf. Auf Basis von Rückmeldungen der Studienteilnehmer:innen wurde das MBFR-Instrument anschließend sprachlich angepasst und gekürzt. Der modifizierte Fragebogen wurde daraufhin in der empirischen Studie „MOBIL bleiben in Stuttgart“ (MBIS) eingesetzt. Dabei sollte die Frage beantwortet werden, ob das finale MBFR-Instrument die zugrundeliegenden Konstrukte valide und reliabel erfasst und die Testwerte somit ausreichende Gültigkeit hinsichtlich faktorieller, Konstrukt- und Kriteriumsvalidität bei älteren Menschen im urbanen Raum aufweisen (Penger & Conrad, eingereicht). Es wurden insgesamt 211 privatwohnende Stuttgarter:innen ab 65 Jahren in persönlichen Interviews und mithilfe eines 7-tägigen Wegetagebuchs zu verschiedenen Aspekten ihrer Mobilität im Wohnumfeld befragt. Statistische Analysen auf latenter Ebene erfolgten mittels Strukturgleichungsmodellen. Bivariate Zusammenhänge und Subgruppenanalysen wurden mittels Korrelations- und Regressionsanalysen berechnet. Die dreifaktorielle Struktur des MBFR-Fragebogens konnte im konfirmatorischen Modell empirisch bestätigt werden. Zudem fiel die interne Konsistenz aller drei Faktoren gut aus. Zusammenhänge zu konstruktverwandten Merkmalen – wie allgemeine und mobilitätsspezifische Einstellungen – deuten darauf hin, dass das MBFR-Instrument ausreichend konvergente Validität aufweist. Analysen auf latenter Ebene ergaben, dass Befragte durchschnittlich mehr außerhäusliche Wege zurückzulegten, wenn sie in stärkerem Maße überzeugt waren, flexibel auf mobilitätsbezogene Herausforderungen reagieren zu können (FLEX). Weiterhin ließen sich positive Zusammenhänge zwischen FLEX und der erlebten Selbstständigkeit sowie dem subjektiven Wohlbefinden aufzeigen. Die Befunde belegen somit hinreichende Übereinstimmungsvalidität der Testwerte. Differenzierte Analysen machten darüber hinaus deutlich, dass FLEX vor allem bei Befragten mit Mobilitätseinschränkungen bedeutsam zur Vorhersage des außerhäuslichen Mobilitätsverhaltens beitrug. ...
Investigation of the sympathetic regulation in delayed onset muscle soreness: results of an RCT
(2021)
Sports-related pain and injury is directly linked to tissue inflammation, thus involving the autonomic nervous system (ANS). In the present experimental study, we disable the sympathetic part of the ANS by applying a stellate ganglion block (SGB) in an experimental model of delayed onset muscle soreness (DOMS) of the biceps muscle. We included 45 healthy participants (female 11, male 34, age 24.16 ± 6.67 years [range 18–53], BMI 23.22 ± 2.09 kg/m2) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative). The aim of the study was to determine whether and to what extent sympathetically maintained pain (SMP) is involved in DOMS processing. Focusing on the muscular area with the greatest eccentric load (biceps distal fifth), a significant time × group interaction on the pressure pain threshold was observed between preventive SGB and sham (p = 0.034). There was a significant effect on pain at motion (p = 0.048), with post hoc statistical difference at 48 h (preventive SGB Δ1.09 ± 0.82 cm VAS vs. sham Δ2.05 ± 1.51 cm VAS; p = 0.04). DOMS mediated an increase in venous cfDNA -as a potential molecular/inflammatory marker of DOMS- within the first 24 h after eccentric exercise (time effect p = 0.018), with a peak at 20 and 60 min. After 60 min, cfDNA levels were significantly decreased comparing preventive SGB to sham (unpaired t-test p = 0.008). At both times, 20 and 60 min, cfDNA significantly correlated with observed changes in PPT. The 20-min increase was more sensitive, as it tended toward significance at 48 h (r = 0.44; p = 0.1) and predicted the early decrease of PPT following preventive stellate blocks at 24 h (r = 0.53; p = 0.04). Our study reveals the broad impact of the ANS on DOMS and exercise-induced pain. For the first time, we have obtained insights into the sympathetic regulation of pain and inflammation following exercise overload. As this study is of a translational pilot character, further research is encouraged to confirm and specify our observations.
Objectives: Current treatments for chronic depression have focused on reducing interpersonal problems and negative affect, but paid little attention to promoting prosocial motivation and positive affect. Following this treatment focus, the objective of the present study was to examine whether the combination of metta (Loving Kindness) group meditation and subsequent tailored individual therapy focusing on kindness towards oneself and others (metta-based therapy, MBT) shows greater improvements in depressive symptoms than a wait list control group in patients with chronic depression. Methods: Forty-eight patients with DSM-5 persistent depressive disorder were randomly assigned to MBT or a wait list control condition. Outcome was assessed after group meditation, after subsequent individual therapy, and at 6-month follow-up. The primary outcome measure was an independent blind rating of depressive symptoms at post-test. Secondary outcome included changes in self-reported depression, behavioral activation, rumination, social functioning, mindfulness, compassion, and clinician-rated emotion regulation. Results: Mixed-design analyses showed significant differences between MBT and WLC in changes from pre- to post-test in clinician-rated and self-rated depression, behavioral activation, rumination, social functioning, mindfulness, and emotion regulation. Most of the changes occurred during group meditation and were associated with large effect sizes. Improvements were maintained at 6-month follow-up. Conclusions: The results provide preliminary support for the effectiveness of MBT in treating chronic depression. Trial Registration: ISRCTN, ISRCTN97264476.
Although researchers and practitioners increasingly focus on health promotion in organizations, research has been mainly fragmented and fails to integrate different organizational levels in terms of their effects on employee health. Drawing on organizational climate and social identity research, we present a cascading model of organizational health climate and demonstrate how and when leaders' perceptions of organizational health climate are linked to employee well-being. We tested our model in two multisource studies (NStudy 1 = 65 leaders and 291 employees; NStudy 2 = 401 leader–employee dyads). Results showed that leaders' perceptions of organizational health climate were positively related to their health mindsets (i.e., their health awareness). These in turn were positively associated with their health-promoting leadership behavior, which ultimately went along with better employee well-being. Additionally, in Study 1, the relationship between perceived organizational health climate and leaders' health mindsets was moderated by their organizational identification. High leader identification strengthened the relationship between perceived organizational health climate and leaders' health mindsets. These findings have important implications for theory and practice as they show how the dynamics of an organizational health climate can unfold in organizations and how it is related to employee well-being via the novel concept of health-promoting leadership.
Strenuous and unaccustomed exercise frequently lead to what has been coined “delayed onset muscle soreness” (DOMS). As implied by this term, it has been proposed that the associated pain and stiffness stem from micro-lesions, inflammation, or metabolite accumulation within the skeletal muscle. However, recent research points towards a strong involvement of the connective tissue. First, according to anatomical studies, the deep fascia displays an intimate structural relationship with the underlying skeletal muscle and may therefore be damaged during excessive loading. Second, histological and experimental studies suggest a rich supply of algogenic nociceptors whose stimulation evokes stronger pain responses than muscle irritation. Taken together, the findings support the hypothesis that DOMS originates in the muscle-associated connective tissue rather than in the muscle itself. Sports and fitness professionals designing exercise programs should hence consider fascia-oriented methods and techniques (e.g., foam rolling, collagen supplementation) when aiming to treat or prevent DOMS.

Background: The promotion of healthy aging is one of the major challenges for healthcare systems in current times. The present study investigates the effects of a standardized physical activity intervention for older adults on cognitive capacity, self-reported health, fear of falls, balance, leg strength and gait under consideration of movement biography, sleep duration, and current activity behavior. Methods: This single-blinded, randomized controlled trial included 49 community-dwelling older adults (36 women; 82.9 ± 4.5 years of age (Mean [M] ± SD); intervention group = 25; control group = 24). Movement biography, sleep duration, cognitive capacity, self-reported health status, and fear of falls were assessed by means of questionnaires. Leg strength, gait, and current activity levels were captured using a pressure plate, accelerometers, and conducting the functional-reach and chair-rising-test. The multicomponent intervention took place twice a week for 45 min and lasted 16 weeks. Sub-cohorts of different sleep duration were formed to distinguish between intervention effects and benefits of healthy sleep durations. Change scores were evaluated in univariate analyses of covariances (ANCOVAs) between groups and sub-cohorts of different sleep duration in both groups. Changes in cognitive capacity, self-reported health, fear of falls, balance, leg strength, and gait were investigated using the respective baseline values, movement biography, and current activity levels as covariates. Analysis was by intention-to-treat (ITT). Results: We found sub-cohort differences in cognitive capacity change scores [F(3,48) = 5.498, p = 0.003, ηp2 = 0.287]. Effects on fear of falls [F(1,48) = 12.961, p = 0.001, ηp2 = 0.240] and balance change scores F(1,48) = 4.521, p = 0.040, ηp2 = (0.099) were modified by the level of current activity. Effects on gait cadence were modified by the movement biography [F(1,48) = 4.545; p = 0.039, ηp2 = 0.100]. Conclusions: Unlike for functional outcomes, our multicomponent intervention in combination with adequate sleep duration appears to provide combinable beneficial effects for cognitive capacity in older adults. Trainability of gait, fear of falls, and flexibility seems to be affected by movement biography and current physical activity levels. Trial registration: This study was registered at the DRKS (German Clinical Trials Register) on November 11, 2020 with the corresponding trial number: DRKS00020472.
We investigated whether dichotomous data showed the same latent structure as the interval-level data from which they originated. Given constancy of dimensionality and factor loadings reflecting the latent structure of data, the focus was on the variance of the latent variable of a confirmatory factor model. This variance was shown to summarize the information provided by the factor loadings. The results of a simulation study did not reveal exact correspondence of the variances of the latent variables derived from interval-level and dichotomous data but shrinkage. Since shrinkage occurred systematically, methods for recovering the original variance were fleshed out and evaluated.
The sudden impact of the COVID-19 pandemic challenged universities to provide students with online teaching and learning settings that were both immediately applicable and supportive of quality learning. This resulted in a broad variety of synchronous and asynchronous online settings of teaching and learning. While some courses balanced both kinds, others offered either predominantly synchronous or asynchronous teaching and learning. In a survey study with students (N=3,056) and teachers (N=396) from a large German university, we explored whether a predominance of synchronous or asynchronous teaching and learning settings in higher education was associated with certain student experiences and outcomes. Additionally, we examined how well these two types of teaching and learning settings support students’ basic psychological needs for autonomy, competence, and relatedness proposed by self-determination theory (SDT). Data were collected after the first online semester due to the COVID-19 pandemic. The results imply that from the students’ perspective, the teaching methods involved in the two settings of teaching and learning differ with regard to their potential to support social interaction and to support basic psychological needs as proposed by SDT. Students who studied mostly in synchronous settings reported more peer-centered activities such as feedback in comparison to students in mostly asynchronous settings. In contrast, teachers perceived fewer differences between teaching methods in synchronous and asynchronous settings, especially regarding feedback activities. Further, students in mostly synchronous settings reported greater support of their basic psychological needs for competence support and relatedness as well as a greater overall satisfaction with the online term compared to students in mostly asynchronous settings. Across all students, greater fulfillment of psychological needs and higher technology acceptance coincided with outcomes that are more favorable. Implications for the post-pandemic classroom are drawn.
Muscular fatigue can affect postural control processes by impacting on the neuromuscular and somatosensory system. It is assumed that this leads to an increased risk of injury, especially in sports such as alpine skiing that expose the body to strong and rapidly changing external forces. In this context, posture constraints and contraction-related muscular pressure may lead to muscular deoxygenation. This study investigates whether these constraints and pressure affect static and dynamic postural control. To simulate impaired blood flow in sports within a laboratory task, oxygen saturation was manipulated locally by using an inflatable cuff to induce blood flow restriction (BFR). Twenty-three subjects were asked to stand on a perturbatable platform used to assess postural-related movements. Using a 2 × 2 within-subject design, each participant performed postural control tasks both with and without BFR. BFR resulted in lower oxygenation of the m. quadriceps femoris (p = 0.024) and was associated with a significantly lower time to exhaustion (TTE) compared to the non-restricted condition [F(1,19) = 16.22, p < 0.001, ηp2 = 0.46]. Perturbation resulted in a significantly increased TTE [F(1,19) = 7.28, p = 0.014, ηp2 = 0.277]. There were no significant effects on static and dynamic postural control within the saturation conditions. The present data indicate that BFR conditions leads to deoxygenation and a reduced TTE. Postural control and the ability to regain stability after perturbation were not affected within this investigation.
With our research, we contribute to the research on proactive work behavior in two ways. First, we examine a person's gender as a boundary condition for proactive behavior at work. Based on social role theory, we argue that women are less likely to receive credit for showing personal initiative (PI) than men. Second, we examine agency and communion as underlying mechanisms that translate PI into a person's evaluation and drive backlash effects. The hypotheses were tested in two complementary experimental studies (Study 1; N = 114, Study 2: N = 163) using simulated job interviews. Our results show that PI relates to better evaluations (likeability, perceived competence, performance evaluations, expected success and hireability) of the job applicant and that these effects are mediated by agency and communion. Further, we find backlash effects for women high in agency and men high in communion on likeability (Study 2). The implications of these results for organizations and future research are discussed.
Individual differences in general cognitive ability (i.e., intelligence) have been linked to individual variations in the modular organization of functional brain networks. However, these analyses have been limited to static (time-averaged) connectivity, and have not yet addressed whether dynamic changes in the configuration of brain networks relate to general intelligence. Here, we used multiband functional MRI resting-state data (N = 281) and estimated subject-specific time-varying functional connectivity networks. Modularity optimization was applied to determine individual time-variant module partitions and to assess fluctuations in modularity across time. We show that higher intelligence, indexed by an established composite measure, the Wechsler Abbreviated Scale of Intelligence (WASI), is associated with higher temporal stability (lower temporal variability) of brain network modularity. Post-hoc analyses reveal that subjects with higher intelligence scores engage in fewer periods of extremely high modularity — which are characterized by greater disconnection of task-positive from task-negative networks. Further, we show that brain regions of the dorsal attention network contribute most to the observed effect. In sum, our study suggests that investigating the temporal dynamics of functional brain network topology contributes to our understanding of the neural bases of general cognitive abilities.
Positive psychological coaching (PPC) has emerged as a popular “paradigm” for practitioners interested in the professional development of people. A recent review consolidated the literature on PPC and produced a 5-phase positive psychological coaching model aimed at facilitating professional growth. However, little is known about practically operationalizing each phase of the coaching process (i.e., how to facilitate each phase and which underlying tools and techniques could be employed to do so). As such, the purpose of this systematic review was to address this limitation by (a) determining which coaching tools and techniques are proposed within the coaching literature and (b) classifying the identified tools and techniques into the respective phases of PPC model. The investigation used a two-step approach by conducting a systematic literature review (to identify various PPC tools/techniques) followed by an iterative heuristic classification process (to assign these PPC tools/techniques to a known PPC model). The systematic literature review resulted in 24 peer-reviewed publications on positive psychological coaching, providing 117 different coaching tools that could be condensed into 18 overarching coaching techniques. The iterative classification process showed that most techniques and tools are useful in at least two phases. Interestingly, experts still vary in opinion on the timing and application of these specific techniques and tools within the positive psychological coaching process. This study provides researchers and practitioners with practical guidelines to facilitate a positive psychological coaching process.
In sports and clinical settings, roller massage (RM) interventions are used to acutely increase range of motion (ROM); however, the underlying mechanisms are unclear. Apart from changes in soft tissue properties (i.e., reduced passive stiffness), neurophysiological alterations such as decreased spinal excitability have been described. However, to date, no study has investigated both jointly. The purpose of this trial was to examine RM’s effects on neurophysiological markers and passive tissue properties of the plantar flexors in the treated (ROLL) and non-treated (NO- ROLL) leg. Fifteen healthy individuals (23 ± 3 years, eight females) performed three unilateral 60-s bouts of calf RM. This procedure was repeated four times on separate days to allow independent assessments of the following outcomes without reciprocal interactions: dorsiflexion ROM, passive torque during passive dorsiflexion, shear elastic modulus of the medial gastrocnemius muscle, and spinal excitability. Following RM, dorsiflexion ROM increased in both ROLL (+19.7%) and NO-ROLL (+13.9%). Similarly, also passive torque at dorsiflexion ROM increased in ROLL (+15.0%) and NO-ROLL (+15.2%). However, there were no significant changes in shear elastic modulus and spinal excitability (p > 0.05). Moreover, significant correlations were observed between the changes in DF ROM and passive torque at DF ROM in both ROLL and NO-ROLL. Changes in ROM after RM appear to be the result of sensory changes (e.g., passive torque at DF ROM), affecting both rolled and non-rolled body regions. Thus, therapists and exercise professionals may consider applying remote treatments if local loading is contraindicated.
Hintergrund: Das Kindesalter wurde bei der Entwicklung von wirksamen Präventions- und Interventionsprogrammen bei Computerspiel- und Internetabhängigkeit bisher kaum berücksichtigt. PROTECTdissonanz wurde daher als 1-stündiges dissonanzbasiertes universelles Primärpräventionsprogramm für die Klassenstufe 5 konzipiert. Die vorliegende Pilotstudie überprüft die unmittelbaren Effekte der Dissonanzinduktion auf die Einstellung zum Gaming. Methodik: In einem einarmigen A+B-Design mit drei Messzeitpunkten (T0, T1, T2) wurde die Einstellung zum Gaming anhand des Gaming Attitude Test (GAT) erfasst. In die Baselinesequenz (Sequenz A, T0 bis T1, Teilstichprobe) wurden N = 83 Schüler_innen eingeschlossen (Alter: M = 10.27; SD = 0.48) und in die Interventionssequenz (Sequenz B, T1 bis T2, Gesamtstichprobe) N = 200 Schüler_innen (Alter: M = 10.24; SD = 0.47). Akzeptanz und Zufriedenheit wurden nach der Intervention erfasst. Ergebnisse: Hierarchisch lineare Wachstumsmodelle zeigten eine signifikante Reduktion der GAT-Symptome durch die Intervention, sowohl im Gesamtwert des GAT als auch auf der Subskala „Bagatellisierung negativer Konsequenzen“. Im natürlichen Verlauf (Baselinesequenz A) zeigten sich keine Veränderungen. Die Schüler_innen bewerteten PROTECTdissonanz zudem mit einer hohen Zufriedenheit. Schlussfolgerungen: Eine kurze, gezielte übung zur Dissonanzinduktion zeigt unmittelbare Effekte auf ein Einstellungsmaß zum Gaming. Zur Weiterverfolgung dieses vielversprechenden Ansatzes sollte in künftigen Studien untersucht werden, ob sich eine verringerte Bagatellisierung negativer Konsequenzen von Gaming im Sinne der kognitiven Dissonanztheorie auch tatsächlich in einer Verhaltensänderung widerspiegelt.
The strengths use scale: psychometric properties, longitudinal invariance and criterion validity
(2021)
Strengths use is an essential personal resource to consider when designing higher-educational programs and interventions. Strengths use is associated with positive outcomes for both the student (e.g., study engagement) and the university (e.g., academic throughput/performance). The Strengths Use Scale (SUS) has become a popular psychometric instrument to measure strengths use in educational settings, yet its use has been subjected to limited psychometric scrutiny outside of the U.S. Further, its longitudinal stability has not yet been established. Given the wide use of this instrument, the goals of this study were to investigate (a) longitudinal factorial validity and the internal consistency of the scale, (b) its equivalence over time, and (c) criterion validity through its relationship with study engagement over time. Data were gathered at two-time points, 3 months apart, from a sample of students in the Netherlands (n = 360). Longitudinal confirmatory factor analyses showed support for a two-factor model for overall strengths use, comprised of Affinity for Strengths and Strengths Use Behaviors. The SUS demonstrated high levels of internal consistency at both the lower- and upper bound limits at both time points. Further, strict longitudinal measurement invariance was established, which confirmed the instrument's temporal stability. Finally, criterion validity was established through relating strengths use to study engagement at different time stamps. These findings support the use of the SUS in practice to measure strengths use and to track the effectiveness of strengths use interventions within the higher education sector.
It is increasingly recognized that neuroscience has not delivered the revolutionary clinical possibilities for psychiatry that had been promised. Explanations differ, however: some proponents emphasize the divide between biopsychosocial psychiatry and mechanistic neurology. Others rely on further basic experimental neuroscience as only the most elementary level of explanation will allow us to fully understand and treat mental disorders. From a clinical-neuropsychological perspective, I shall argue that both views are mistaken. Diagnosis and treatment of neurological diseases demands a biopsychosocial perspective similar to psychiatry. Acknowledging this might help to bring both disciplines together and improve clinical outcome.
As knowledge derived from scientific theory can be helpful for teachers to reflect on their everyday teaching, universities have the challenging task of teaching this knowledge in such a way that pre-service teachers are able to apply it to their later teaching. Case-based learning has emerged as a promising method to foster pre-service teachers’ scientific knowledge application throughout university teacher education. However, surprisingly, empirical evidence for its effectiveness as compared to more traditional instructional interventions in teacher education is still inconclusive, partly being due to constraints concerning the employed comparison groups. The present quasi-experimental study (conducted in the field of classroom management) investigated the effect of studying exactly the same theoretical content with and without text-based cases on scientific knowledge application (as measured by a vignette test) in a sample of 101 pre-service teachers. Although the study found a small advantage for the case-based learning group, it demonstrated that scientific knowledge application may also be effectively fostered in a more traditional instructional course. The findings and their implications are discussed against the background of cognitive theories on inert knowledge and how to prevent it in teacher education.
Um Unterricht durch digitale Medien lernwirksam gestalten zu können, sollten Lehrkräfte über die notwendigen Kompetenzen für einen didaktisch angemessenen und reflektieren Einsatz von Technologien verfügen. Neben der Verbesserung der technischen Infrastruktur an Schulen ist es daher notwendig, Lehrkräfte bei ihrer Professionalisierung zu unterstützen. Lehrkräfte an deutschen Schulen zeigen allerdings eine eher zurückhaltende Teilnahme an Fortbildungsangeboten zu digitalen Themen, was auf eine fehlende Passung zu den realen Bedarfen hinweisen kann. Der vorliegende Beitrag widmet sich daher Präferenzen von Lehrkräften zu Inhalten und Gestaltungsmerkmalen von Fortbildungen zu digitalen Medien und berichtet dazu Ergebnisse einer Befragung von Gymnasiallehrkräften (N = 238). Um möglichst zielgruppenspezifische Ergebnisse zu erhalten, wurden über eine latente Profilanalyse mit Personenmerkmalen (technologisches und technologisch-pädagogisches Wissen, Selbstwirksamkeit, Mediennutzung) drei Profile identifiziert und im Hinblick auf ihre Präferenzen verglichen. Die Ergebnisse weisen auf eine Vielfalt an thematischen Wünschen sowie auf die Notwendigkeit einer bedarfsgerechten Gestaltung von Fortbildungen hin. Abschließend werden zusammenfassende Empfehlungen zur Gestaltung von Lehrkräftefortbildungen zu digitalen Medien formuliert.
Background: This article reports reliability, validity, and norms for the German version of the multi-informant questionnaire Inventory of Callous–Unemotional Traits (ICU). Method: The ICU was filled in by nonreferred children aged 13 to 18 years old (n = 645), parents of children aged 6 to 18 years old (n = 1,005), and their teachers (n = 955). Results: Confirmatory factor analysis resulted in a two-factor solution giving the best fit. Still none of the models showed an adequate model-fit applying the chi-square exact fit test. The internal consistency of the parent’s, teacher’s, and self-report version were α = .830, α = .877 and α = .769, respectively. Interrater reliability was moderate. Convergent validity with the Youth Psychopathic Traits Inventory, the externalizing scores of the Youth Self-Report/Child Behavior Checklist, and with the German oppositional Defiant Disorder/Conduct Disorder Rating Scale “FBB-SSV” were good. German norms were calculated. Conclusions: The ICU is a reliable and valid dimensional measure to describe callous–unemotional traits.
The COVID-19 lockdown has significantly disrupted the higher education environment within the Netherlands and led to changes in available study-related resources and study demands of students. These changes in study resources and study demands, the uncertainty and confusion about educational activities, the developing fear and anxiety about the disease, and the implementation of the COVID-19 lockdown measures may have a significant impact on the mental health of students. As such, this study aimed to investigate the trajectory patterns, rate of change, and longitudinal associations between study resources–demands and mental health of 141 university students from the Netherlands before and during the COVID-19 lockdown. The present study employed a longitudinal design and a piecewise latent growth modeling strategy to investigate the changes in study resources and mental health over a 3 month period. The results showed that moderate levels of student resources significantly decreased before, followed by a substantial rate of increase during, lockdown. In contrast, study demands and mental health were reported to be moderate and stable throughout the study. Finally, the growth trajectories of study resources–demands and mental health were only associated before the lockdown procedures were implemented. Despite growing concerns relating to the negative psychological impact of COVID-19 on students, our study shows that the mental health during the initial COVID-19 lockdown remained relatively unchanged.
Background: Handball referees play an important role during a handball match. Surprisingly, not much is known about their sports-related injuries and resulting pain, therefore the purpose of our study was to focus on injuries and sports-related pain in referees in German handball leagues. Methods: During the 2018/19 national German handball season, referees of the German Federation of Handball (DHB) were contacted and asked to complete an injury and pain questionnaire on the penultimate matchday of the first and the second round of the season. Results: Seventy referees participated in the study. One in three referees reported an injury during the last year and perceived some form of pain. Of those suffering from pain, 16.7% referees reported chronic pain disorders. During the season, 31.4% of referees incurred an injury and the majority of the 70 referees officiated despite pain (n = 43). Prospectively-enrolled data suggested an incidence of 11.6 (95% CI: 10.3 to 13.0) injuries per 1000 match hours, and 19.0 (95% CI: 16.8 to 21.3) sports-related pain events per 1000 match hours. The most common injuries were foot and knee injuries and a substantial number of the referees (n = 25) reported taking analgesics for the pain. Conclusion: German handball referees are at risk of sports-related injuries with subsequent pain. Considering the injury profile, the incidence of sports-related pain events, and the high physiological demands of refereeing, it appears that prevention programs should be developed and integrated into the routine of the referee.
We wish to make the following correction to the published paper 'Effects of Transient Loss of Vision on Head and Eye Movements during Visual Search in a Virtual Environment'. We have identified a flaw in the implementation of a latency mitigation strategy for our gaze-contingent protocol written in Unity3D. As a result, the maximum latency is now estimated to be 30 ms instead of 15 ms, which should not affect any of the results originally published but should be noted for further reference.
We aimed to assess executive functioning in children after liver transplantation compared with healthy controls and in relation to real-life school performance using the PedsQLTM Cognitive Functioning Scale (CogPedsQL) and the Childrens’ Color Trail Test (CCTT). One hundred and fifty five children (78f, median age 10.4 (1.2–18.3) years) underwent testing with CogPedsQL and/or CCTT 4.9 (0.1–17.0) years after transplantation. Results were compared to those of 296 healthy children (165f, median age 10.0 (2.0–18.0) years). Liver transplanted children displayed significantly reduced scores for cogPedsQL and CCTT1&2 compared to healthy controls. Overall, school performance was lower in patients compared to controls. In both patients and controls, results of CCTT2 and CogPedsQL correlated strongly with school performance. In contrast to controls, school performance in patients correlated with the level of maternal but not paternal primary education degree (r = −0.21, p = 0.03). None of the patient CCTT or CogPedsQL test results correlated with parental school education. Conclusion: CogPedsQL and CCTT 1&2 were easily applicable in children after OLT and revealed reduced executive functioning compared to controls. Results reflect real life school performance. The association of parental education with school performance is reduced in transplanted children, which possibly indicates the overriding impact of transplant-associated morbidity on cognitive outcomes.

Feasibility of present-centered therapy for prolonged grief disorder: results of a pilot study
(2021)
Present-centered therapy (PCT) was originally developed as a strong comparator for the non-specific effects of psychotherapy in the treatment of posttraumatic stress disorder. PCT qualifies as a not strictly supportive treatment as it is structured and homework is assigned between sessions. It does not focus on cognitive restructuring or exposure. A growing body of literature supports its beneficial effects. For example, it demonstrated only slightly inferior effect sizes and lower dropout rates compared to that of trauma-focused cognitive behavioral therapy in several trials with patients suffering from posttraumatic stress disorder. The current study is the first to evaluate the feasibility and the treatment effects of PCT in adults with prolonged grief disorder (PGD). Meta-analyses on psychotherapy for PGD have yielded moderate effect sizes. N = 20 individuals suffering from PGD were treated with PCT by novice therapists as part of a preparation phase for an upcoming RCT in an outpatient setting. Treatment consisted of 20–24 sessions á 50 min. All outcomes were assessed before treatment, at post-treatment, and at the 3-month follow-up. The primary outcome, PGD symptom severity, was assessed using the Interview for Prolonged Grief-13. Secondary outcomes were self-reported PGD severity, depression, general psychological distress, and somatic symptom severity. Furthermore, therapists evaluated their experiences with their first PCT patient and the treatment manual. In intent-to-treat analyses of all patients we found a significant decrease in interview-based PGD symptom severity at post-treatment (d = 1.26). Decreases were maintained up to the 3-month follow-up assessment (d = 1.25). There were also significant decreases in self-reported PGD symptoms, depression, and general psychological distress. No changes were observed for somatic symptoms. The completion rate was 85%. Therapists deemed PCT to be a learnable treatment program that can be adapted to the patient's individual needs. The preliminary results of PCT as a treatment for PGD demonstrate large effects and indicate good feasibility in outpatient settings. The treatment effects were larger than those reported in meta-analyses. Thus, PCT is a promising treatment for PGD. Possible future research directions are discussed.
Working memory capacity (WMC) and fluid intelligence (Gf) are highly correlated, but what accounts for this relationship remains elusive. Process-overlap theory (POT) proposes that the positive manifold is mainly caused by the overlap of domain-general executive processes which are involved in a battery of mental tests. Thus, executive processes are proposed to explain the relationship between WMC and Gf. The current study aims to (1) achieve a relatively purified representation of the core executive processes including shifting and inhibition by a novel approach combining experimental manipulations and fixed-links modeling, and (2) to explore whether these executive processes account for the overlap between WMC and Gf. To these ends, we reanalyzed data of 215 university students who completed measures of WMC, Gf, and executive processes. Results showed that the model with a common factor, as well as shifting and inhibition factors, provided the best fit to the data of the executive function (EF) task. These components explained around 88% of the variance shared by WMC and Gf. However, it was the common EF factor, rather than inhibition and shifting, that played a major part in explaining the common variance. These results do not support POT as underlying the relationship between WMC and Gf.
Bisherige Forschungsergebnisse zeigen, dass auch Frauen sexuellen Kindesmissbrauch begehen und somit eine potentielle Gefahr für das Kindeswohl darstellen können. Aus Deutschland liegen bisher nur regionale oder Studien mit geringer Stichprobengröße vor. Die vorliegende Studie verfolgt das Ziel, eine umfassende Bestandserhebung des sexuellen Kindesmissbrauchs durch Frauen in Deutschland zu dokumentieren. Im Rahmen der vorliegenden Untersuchung wurden zum ersten Mal bundesweit Strafakten von 465 pädokriminellen Frauen ausgewertet, die in den letzten 30 Jahren nach §§174, 176, 180 oder 182 des StGB verurteilt wurden. Die standardisierte Analyse umfasst 185 Variablen und 54 selbst definierte Skalen. Die Ergebnisse zeigen, dass eine pädokriminelle Frau durchschnittlich 33 Jahre alt ist, zumeist in einer Ehe in einer Kleinstadt lebt und häufig keiner beruflichen Tätigkeit nachgeht. Sie ist eine Mittäterin, handelt überwiegend aus Abhängigkeit zu ihrem männlichen Komplizen heraus, zu dem sie eine intime Beziehung pflegt und missbraucht mehrheitlich weibliche Opfer (Verhältnis fast 2:1). Beinahe die Hälfte der 614 Opfer, zu denen Informationen vorlagen, waren leibliche Kinder der Täterinnen und rund jedes sechste Kind stammte vom männlichen Mittäter.
The COVID-19 pandemic led to numerous governments deciding to close schools for several weeks in spring 2020. Empirical evidence on the impact of COVID-19-related school closures on academic achievement is only just emerging. The present work aimed to provide a first systematic overview of evidence-based studies on general and differential effects of COVID-19-related school closures in spring 2020 on student achievement in primary and secondary education. Results indicate a negative effect of school closures on student achievement, specifically in younger students and students from families with low socioeconomic status. Moreover, certain measures can be identified that might mitigate these negative effects. The findings are discussed in the context of their possible consequences for national educational policies when facing future school closures.
Taking blood via venipuncture is part of the necessary surveillance before and after liver transplantation. The spectrum of response from children and their parents is variable, ranging from a short and limited aversion to paralyzing phobia. The aim of this retrospective, cross-sectional study was to determine the level of anxiety amongst children during venipuncture, to compare the anxiety reported by children and parents, and to identify the factors affecting the children’s and parents’ anxiety in order to develop therapeutic strategies. In total, 147 children (aged 0–17 years, 78 female) and their parents completed questionnaires. Statistical analysis was performed using qualitative and quantitative methods. Results showed that the majority of children reported anxiety and pain during venipuncture. Younger children had more anxiety (self-reported or assessed by parents). Children and parental reports of anxiety were highly correlated. However, the child’s anxiety was often reported as higher by parents than by the children themselves. The child’s general anxiety as well as the parents’ perceived stress from surgical interventions (but not the number of surgical interventions) prompted parental report of child anxiety. For children, the main stressors that correlated with anxiety and pain were factors during the blood collection itself (e.g., feeling the puncture, seeing the syringe). Parental anxiety was mainly related to circumstances before the blood collection (e.g., approaching the clinic, sitting in the waiting room). The main stressors mentioned by parents were the child’s discomfort and their inability to calm the child. Results indicate that the children’s fear of factors during the blood collection, along with the parents’ perceived stress and helplessness as well as their anticipatory anxiety are important starting points for facilitating the drawing of blood from children before and after liver transplantation, thereby supporting a better disease course in the future.
Purpose: Physical activity is associated with altered levels of circulating microRNAs (ci-miRNAs). Changes in miRNA expression have great potential to modulate biological pathways of skeletal muscle hypertrophy and metabolism. This study was designed to determine whether the profile of ci-miRNAs is altered after different approaches of endurance exercise. Methods: Eighteen healthy volunteers (aged 24 ± 3 years) participated this three-arm, randomized-balanced crossover study. Each arm was a single bout of treadmill-based acute endurance exercise at (1) 100% of the individual anaerobic threshold (IANS), (2) at 80% of the IANS and (3) at 80% of the IANS with blood flow restriction (BFR). Load-associated outcomes (fatigue, feeling, heart rate, and exhaustion) as well as acute effects (circulating miRNA patterns and lactate) were determined. Results: All training interventions increased the lactate concentration (LC) and heart rate (HR) (p < 0.001). The high-intensity intervention (HI) resulted in a higher LC than both lower intensity protocols (p < 0.001). The low-intensity blood flow restriction (LI-BFR) protocol led to a higher HR and higher LC than the low-intensity (LI) protocol without BFR (p = 0.037 and p = 0.003). The level of miR-142-5p and miR-197-3p were up-regulated in both interventions without BFR (p < 0.05). After LI exercise, the expression of miR-342-3p was up-regulated (p = 0.038). In LI-BFR, the level of miR-342-3p and miR-424-5p was confirmed to be up-regulated (p < 0.05). Three miRNAs and LC show a significant negative correlation (miR-99a-5p, p = 0.011, r = − 0.343/miR-199a-3p, p = 0.045, r = − 0.274/miR-125b-5p, p = 0.026, r = − 0.302). Two partial correlations (intervention partialized) showed a systematic impact of the type of exercise (LI-BFR vs. HI) (miR-99a-59: r = − 0.280/miR-199a-3p: r = − 0.293). Conclusion: MiRNA expression patterns differ according to type of activity. We concluded that not only the intensity of the exercise (LC) is decisive for the release of circulating miRNAs—as essential is the type of training and the oxygen supply.
In memory of Edward Diener: reflections on his career, contributions and the science of happiness
(2021)
Prof. Edward (Ed) Diener (1946-2021), a pioneer in positive psychology, passed away on the 27th of April 2021 at his home in Salt Lake City, Utah (Salt Lake City Tribune, 2021). As one of the most influential psychologists of the discipline, Ed Diener pushed the boundaries of our understanding of positive psychological functioning, subjective well-being, and happiness (Layous, 2020). As one of the Top 200 most cited researchers across all disciplines and fields, he will be most remembered for founding the scientific study of subjective well-being (SWB) and happiness (Bakshi, 2019). Diener developed the concept of subjective well-being by exploring the factors that influence people's life satisfaction (Diener et al., 2017a). He studied the individual causes of subjective well-being, such as close social relationships, income, meaning and purpose, personality, and societal causes, such as economic development, low corruption and crime, and a healthy environment (Diener et al., 2018). His research has discovered both universal and culture-specific causes and consequences of SWB and influenced governmental policy (Oishi et al., 1999). In respect of his memory, the purpose of this paper is threefold: (a) to reflect upon his career journey, (b) to celebrate his significant contributions to the discipline, and (c) to provide personal reflections of those who worked closely with him over the past 50 years.
Misconceptions about scientific concepts often prevail even if learners are confronted with conflicting evidence. This study tested the facilitative role of surprise in children’s revision of misconceptions regarding water displacement in a sample of German children (N = 94, aged 6–9 years, 46% female). Surprise was measured via the pupil dilation response. It was induced by letting children generate predictions before presenting them with outcomes that conflicted with their misconception. Compared to a control condition, generating predictions boosted children’s surprise and led to a greater revision of misconceptions (d = 0.56). Surprise further predicted successful belief revision during the learning phase. These results suggest that surprise increases the salience of a cognitive conflict, thereby facilitating the revision of misconceptions.
The reading acceleration phenomenon refers to the effect that experimentally induced time constraints can generate instantaneous improvements of reading rate, accuracy and comprehension among typical and reading impaired readers of different age groups. An overview of studies applying the fading manipulation (i.e., letters are erased in reading direction), which induces the time constraints causing the acceleration phenomenon, is provided in the first part of this review. The second part summarises the outcomes of studies using a training approach called the reading acceleration program (RAP) that integrated core principles of the acceleration phenomenon to generate persistent reading performance improvements. Our review shows ample evidence for the validity of the acceleration phenomenon, since it has been replicated across various languages and populations. However, although there are several explanatory approaches for underlying mechanisms, none of them is well substantiated by empirical evidence so far. Similarly, although generally positive effects of RAP training were reported for several languages and groups of readers, the exact mechanisms causing improved reading rates and comprehension are not well understood. Our critical discussion points out several limitations of RAP that call for further research. However, we also highlight several benefits regarding RAP's potential as an intervention approach for enhancements in reading performance. Video abstract link: https://youtu.be/wO6aEXavk8w
Objective: To compare narrative coping with physical and psychological ambiguous loss (AL) and definite loss in terms of distancing (vs. narrative immersion), meaning-making, and subjective biographical consequences.
Methods: Thirty adults who had lost a parent to death, to going missing, or to Alzheimer disease (N = 90, 67 females; mean age 36.73 years, SD = 7.27; mean time since loss 9.0 years) narrated two loss-related and three control memories.
Results: Individuals with AL were not more immersed in the loss experience, but less successful in finding meaning and in evaluating the loss and its consequences positively compared to those with a definite loss. These group differences were not due to differences in depression, posttraumatic stress disorder, and protracted grief.
Conclusions: Ambiguity of loss renders meaning-making and coherently narrating loss more difficult, leading to more negative affect, suggesting interventions that help narrating loss coherently in a self-accepting way.
We extended the job demand–control model by including a social comparison perspective and hypothesised that an employee's work-related well-being is to some degree relative to the perceived work environment of coworkers rather than absolute (in terms of isolated effects of individual work characteristics). Hence, we account for the social context when examining the effects of individual job characteristics. Using a lagged study design with two measurement times eight weeks apart, we examined the effects of the (in)congruence between one´s own job demands and job control with the perceived job demands and job control of coworkers on job satisfaction, emotional exhaustion, cynicism, and professional efficiency. Findings from polynomial regression analyses and response surface methodology revealed that perceiving coworkers as having either higher or lower demands than oneself is associated with lower job satisfaction and higher levels of emotional exhaustion. This provides partial support for our hypotheses. We found first-time evidence that social comparison processes regarding job demands can influence employees´ well-being.
Objective: The problematic use of computer games was included in the DSM-5 and in the ICD-11. Initial research revealed associa- tions between problematic gaming (PG) and quality of life (QoL). However, clarification is needed concerning which dimensions of the multidi- mensional construct QoL are particularly relevant for PG. Method: To answer this question empirically, we asked 503 parents (mean age: 47.63 years) to rate their 503 children (average age: 14.60 years) regarding QoL and PG, using validated questionnaires on parental assessments of adolescent PG and health-related QoL to collect the data. Correlation analyses were calculated to determine bivariate relations, and a multiple linear regression was used to conduct a multivariable analysis. Results: In the bivariate analyses, a higher severity of PG was associated with a lower health-related QoL in all five surveyed dimensions. In the multivariable model (corrected R2 = 0.35), we observed statistically significant associations between higher severity of PG and male sex and lower age of the adolescent as well as lower QoL in the dimensions of physical well-being and school environment. Conclusions: According to the findings of the present study, physical well-being and school environment should be especially focused on in preventive approaches against the development of PG in youth.
Despite the increasing interest in leaders’ health-promoting behavior, the employees’ role in the effectiveness of such behavior and the mechanisms underlying how such leadership behavior affects their well-being have largely been ignored. Drawing on implicit leadership theories, we advance the health-oriented leadership literature by examining employees’ ideals, that is, their expectations regarding such leader behavior, as a moderating factor. We propose that higher expectations increase the association between actual health-oriented leader behavior and employee-rated leader-member relationships (LMX) and health-oriented behaviors by employees, which, in turn, positively relate to their well-being (here: exhaustion and work engagement). We tested our theoretical model in three studies, using a cross-sectional design (Study 1, N = 307), a two-wave time-lagged design (Study 2, N = 144) and an experimental design (Study 3, N = 173). We found that the effect of actual health-oriented leader behavior on LMX is contingent on employees’ ideal health-oriented leader behavior. Yet, for employees’ self-care behavior, the proposed moderation was only significant in Study 1. High expectations strengthened the relationship between actual health-oriented leader behavior with LMX and self-care behavior, which, in turn, were associated with less exhaustion and more work engagement (only LMX), supporting most of our mediation hypotheses. Our results highlight the pivotal role of employees’ expectations regarding leaders’ health support and help in building practical interventions with regard to leaders’ health promotion.
