Responses to the COVID-19 pandemic prompted people and institutions to turn to online virtual environments for a wide variety of social gatherings. In this perspectives article, we draw upon our previous work and interviews with Ghanaian Christian leaders to consider implications of this shift. Specifically, we propose that the shift from physical to virtual interactions mimics and amplifies the neoliberal individualist experience of abstraction from place associated with Eurocentric modernity. On the positive side, the shift from physical to virtual environments liberates people to selectively pursue the most fulfilling interactions, free from constraints of physical distance. On the negative side, the move from physical to virtual space necessitates a shift from material care and tangible engagement with the local community to the psychologization of care and pursuit of emotional intimacy in relations of one’s choosing—a dynamic that further marginalizes people who are already on the margins. The disruptions of the pandemic provide an opportunity to re-set social relations, to design ways of being that better promote sustainable collective well-being rather than fleeting personal fulfillment.
Personal values are considered as guiding principles for humans’ attitudes and behavior, what makes them an essential component of mental health. Although these notions are widely recognized, investigations in clinical samples examining the link between values and mental health are lacking. We assessed n = 209 patients with affective disorders, neurotic disorders, reaction to severe stress, and adjustment disorders and personality disorders and compared them to a stratified random sample (n = 209) drawn from the European Social Survey. Personal values were assessed using the Portraits Value Questionnaire. Severity of psychopathology was assessed using the Beck Depression Inventory and the Brief Symptom Inventory. Clinical participants showed a higher preference for the values power, achievement and tradition/conformity and a lower preference for hedonism compared to controls. Patients exhibited more incompatible value patterns than controls. Across diagnostic groups, patients with neurotic disorders reported incompatible values most frequently. Value priorities and value conflicts may have the potential to contribute to a better understanding of current and future actions and experiences in patients with mental disorders.
Lexical access speed and the development of phonological recoding during immediate serial recall
(2022)
A recent Registered Replication Report (RRR) of the development of verbal rehearsal during serial recall revealed that children verbalized at younger ages than previously thought, but did not identify sources of individual differences. Here, we use mediation analysis to reanalyze data from the 934 children ranging from 5 to 10 years old from the RRR for that purpose. From ages 5 to 7, the time taken for a child to label pictures (i.e. isolated naming speed) predicted the child’s spontaneous use of labels during a visually presented serial reconstruction task, despite no need for spoken responses. For 6- and 7-year-olds, isolated naming speed also predicted recall. The degree to which verbalization mediated the relation between isolated naming speed and recall changed across development. All relations dissipated by age 10. The same general pattern was observed in an exploratory analysis of delayed recall for which greater demands are placed on rehearsal for item maintenance. Overall, our findings suggest that spontaneous phonological recoding during a standard short-term memory task emerges around age 5, increases in efficiency during the early elementary school years, and is sufficiently automatic by age 10 to support immediate serial recall in most children. Moreover, the findings highlight the need to distinguish between phonological recoding and rehearsal in developmental studies of short-term memory.
Previous research has demonstrated the efficacy of psychological interventions to foster resilience. However, little is known about whether the cultural context in which resilience interventions are implemented affects their efficacy on mental health. Studies performed in Western (k = 175) and Eastern countries (k = 46) regarding different aspects of interventions (setting, mode of delivery, target population, underlying theoretical approach, duration, control group design) and their efficacy on resilience, anxiety, depressive symptoms, quality of life, perceived stress, and social support were compared. Interventions in Eastern countries were longer in duration and tended to be more often conducted in group settings with a focus on family caregivers. We found evidence for larger effect sizes of resilience interventions in Eastern countries for improving resilience (standardized mean difference [SMD] = 0.48, 95% confidence interval [CI] 0.28 to 0.67; p < 0.0001; 43 studies; 6248 participants; I2 = 97.4%). Intercultural differences should receive more attention in resilience intervention research. Future studies could directly compare interventions in different cultural contexts to explain possible underlying causes for differences in their efficacy on mental health outcomes.
Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.
Systemic therapy considers the complex dynamics of relational factors and resources contributing to psychological symptoms. Negative maintaining factors have been well researched for people suffering from Alcohol-use Disorders (AUD). However, we know little about the complex dynamics of these negative factors and resources. We interviewed fifty-five participants suffering or fully remitted from Alcohol-use disorders in this cross-sectional study (M = 52 years; 33% female). The interviews focused on relational factors (e.g., social support and social negativity) referring to a Support Social Network and a Craving Social Network (CSN). The CSN included all significant others who were associated with craving situations. We compared the network characteristics of the group suffering from Alcohol-use Disorders (n = 38) to a fully remitted control group (n = 17). The abstinent group with full remission named on average fewer individuals in the CSNs. They had lower social negativity mean scores in the Support Social Network compared to the non-remitted group (d = 0.74). In the CSN, the mean scores of social support were significantly higher than the median for both groups (d = 2.50). These findings reveal the complex interplay of relational patterns contributing to the etiology, maintenance, and recovery from Alcohol-use disorders. A successful recovery can be linked to increased social resources and reduced relations associated with craving. However, craving-associated relations represent an important source of social support. Future research should investigate this ambivalence for the systemic perspective on the explanation and treatment of Alcohol-use disorders.
Humans accumulate knowledge throughout their entire lives. In what ways does this accumulation of knowledge influence learning of new information? Are there age-related differences in the way prior knowledge is leveraged for remembering new information? We review studies that have investigated these questions, focusing on those that have used the memory congruency effect, which provides a quantitative measure of memory advantage because of prior knowledge. Regarding the first question, evidence suggests that the accumulation of knowledge is a key factor promoting the development of memory across childhood and counteracting some of the decline in older age. Regarding the second question, evidence suggests that, if available knowledge is controlled for, age-related differences in the memory congruency effect largely disappear. These results point to an age-invariance in the way prior knowledge is leveraged for learning new information. Research on neural mechanisms and implications for application are discussed.
Fitness and exercise may counteract the detrimental metabolic and mood adaptations during prolonged sitting. This study distinguishes the immediate effects of a single bout vs. work-load and intensity-matched repeated exercise breaks on subjective well-being, blood glucose, and insulin response (analyzed as area under the curve) during sedentary time; and assesses the influence of fitness and caloric intake on metabolic alterations during sedentariness. Eighteen women underwent cardiopulmonary exercise testing and three 4 h sitting interventions: two exercise interventions (70% VO2max, 30 min, cycle ergometer: (1) cycling prior to sitting; (2) sitting interrupted by 5 × 6 min cycling), and one control condition (sitting). Participants consumed one meal with ad libitum quantity (caloric intake), but standardized macronutrient proportion. Exercise breaks (4057 ± 2079 μU/mL·min) reduced insulin values compared to a single bout of exercise (5346 ± 5000 μU/mL·min) and the control condition (6037 ± 3571 μU/mL·min) (p ≤ 0.05). ANCOVA revealed moderating effects of caloric intake (519 ± 211 kilocalories) (p ≤ 0.01), but no effects of cardiorespiratory fitness (41.3 ± 4.2 mL/kg/min). Breaks also led to lower depression, but higher arousal compared to a no exercise control (p ≤ 0.05). Both exercise trials led to decreased agitation (p ≤ 0.05). Exercise prior to sitting led to greater peace of mind during sedentary behavior (p ≤ 0.05). Just being fit or exercising prior to sedentary behavior are not feasible to cope with acute detrimental metabolic changes during sedentary behavior. Exercise breaks reduce the insulin response to a meal. Despite their vigorous intensity, breaks are perceived as positive stimulus. Detrimental metabolic changes during sedentary time could also be minimized by limiting caloric intake.
Im Rahmen der fortschreitenden Digitalisierung der Hochschullehre finden auch verstärkt elektronische Prüfungsformate Eingang in den Alltag von Hochschulen. Insbesondere elektronische Abschlussklausuren (E-Klausuren) bieten hier die Möglichkeit, die Prüfungsbelastung Hochschulehrender durch die Automatisierung weiter Teile der Klausurkonstruktion, -administration und -auswertung zu reduzieren. Die Integration digitaler Technologien in die Prüfungspraxis deutscher Hochschulen ermöglicht dabei nicht nur eine ökonomische Klausurkonstruktion, realitätsnähere Klausuren (z. B. durch die Nutzung fachspezifischer Standardsoftware), und den Einsatz innovativer Testbausteine (z. B. Integration von Multimediadateien in Items), sondern auch die Nutzung aktueller psychometrischer Methoden. Insbesondere die Konstruktion von Hochschulklausuren als kriteriumsorientierte, adaptive Tests (z. B. Spoden & Frey, 2021), hat das Potential Hochschulklausuren individualisierter, messpräzisier und fairer zu machen, sowie die Validität der aus der Klausurbearbeitung abgeleiteten Testwertinterpretationen zu steigern. Um kriteriumsorientierte, adaptive Hochschulklausuren in der Breite nutzbar zu machen, müssen allerdings zuvor einige Herausforderungen gemeistert werden, denen sich diese Arbeit widmet. Die in den vier Einzelarbeiten dieser Dissertation betrachteten Herausforderungen lassen sich auf einer psychometrischen, einer personalen und einer technischen Ebene verorten.
Auf der psychometrischen Ebene ist eine zentrale Herausforderung die ökonomische Kalibrierung des Itempools. Üblicherweise wird bei der Konstruktion adaptiver Tests eine dreistellige Anzahl an Items konstruiert und mittels einer separaten Kalibrierungsstudie im Vorlauf der operationalen Testanwendung mit mehreren hundert Testpersonen kalibriert. Die massierte Konstruktion vieler Items und die Durchführung einer zusätzlichen empirischen Studie lässt sich im Rahmen von Hochschulklausuren nur schwer realisieren. Im ersten Einzelbeitrag wird daher eine neuartige kontinuierliche Kalibrierungsstrategie (KKS) vorgestellt und im Rahmen einer Monte-Carlo-Simulation hinsichtlich ihrer psychometrischen Eigenschaften geprüft. Zusammenfassend ermöglicht die KKS, adaptive Tests während wiederkehrender Testanwendungen bei konstanter Berichtsmetrik, Kontrolle von Itemparameter-Drift und fortlaufender Ergänzung des Itempools zu kalibrieren. Es zeigt sich, dass die KKS selbst für sehr kleine Stichproben eine geeignete Methode darstellt, den Itempool über mehrere Testanwendungen hinweg fortlaufend zu kalibrieren.
Um die Berichtsmetrik dabei über die verschiedenen Testanwendungen hinweg konstant zu halten, und somit Vergleichbarkeit der Ergebnisse verschiedener Testzeitpunkte (z. B. Semester) zu gewährleisten, nutzt die KKS Equating-Methoden (z. B. Kolen & Brennan, 2014) zum Herstellen einer statistischen Verbindung zwischen Klausurdurchläufen. Die Qualität dieser statistischen Verbindung hängt dabei von verschiedenen Parametern ab. Im zweiten Einzelbeitrag werden daher verschiedene Konfigurationen der in die KKS implementierten Equating-Prozedur hinsichtlich ihres Einflusses auf die Qualität der Parameterschätzungen im Rahmen einer Monte-Carlo-Simulation untersucht und auf Basis der Ergebnisse praktische Empfehlungen abgleitet. Hierfür werden unter anderem die Schwierigkeitsverteilung der genutzten Linkitems sowie die verwendete Skalentransformationsmethode variiert. Es zeigt sich, dass die KKS unter verschiedenen Konfigurationen in der Lage ist, die Skala über mehrere Testzyklen hinweg konstant zu halten. Normal- beziehungsweise gleichverteile Schwierigkeitsverteilungen der Linkitems sowie die Stocking-Lord-Skalentransformationsmethode (Stocking & Lord, 1983) erweisen sich hierbei am vorteilhaftesten.
Auf personaler Ebene stellt die Akzeptanz seitens der Hochschullehrenden einen kritischen Erfolgsfaktor für die Implementation neuer E-Learning Systeme in Lehrveranstaltungen dar. Angelehnt an Technologieakzeptanzmodellen (z. B. Technology Acceptance Model; Davis, 1989) wird im dritten Einzelbeitrag ein empirisch prüfbares Modell – das Technology-based Exams Acceptance Model (TEAM) – zur Vorhersage der Intention zur Nutzung von adaptiven und nicht-adaptiven E-Klausursystemen seitens Hochschullehrender vorgeschlagen und anhand der Daten von N = 993 deutschen Hochschullehrenden empirisch geprüft. Das postulierte Modell weist einen guten Modellfit auf. Die Ergebnisse weisen die wahrgenommene Nützlichkeit als Schlüsselprädiktor für die Nutzungsintention aus. Medienbezogene Variablen haben indirekte Effekte auf die wahrgenommene Nützlichkeit, mediiert über vorherige Nutzungserfahrungen mit Bildungstechnologien. Darüber hinaus spielt die subjektive Norm eine wichtige Rolle bei der Erklärung der Akzeptanz von E-Klausuren...
Background: Multiple traumata such as child sexual and/or physical abuse often result in complex psychopathologies and a range of associated dysfunctional behaviors. Although evidence-based interventions exist, some therapists are concerned that trauma-focused psychotherapy with exposure-based elements may lead to the deterioration of associated dysfunctional behaviors in adolescents and young adults. Therefore, we examined the course of suicidal ideation, self-injury, aggressive behavior and substance use in a group of abuse-related posttraumatic stress disorder (PTSD) patients during phase-based, trauma-focused PTSD treatment.
Methods: Daily assessments from a randomized controlled trial (RCT) of Developmentally adapted Cognitive Processing Therapy (D-CPT) were analyzed to test for differences in the stated dysfunctional behaviors between the four treatment phases. We conducted multilevel modeling and repeated measure ANOVAs.
Results: We did not find any significant differences between the treatment phases concerning the stated dysfunctional behaviors, either at the level of urge or at the level of actual actions. On the contrary, in some primary outcomes (self-injury, aggressive behavior), as well as secondary outcomes (distress caused by trauma, joy), we observed significant improvements.
Discussion: Overall, during D-CPT, adolescents and young adults showed no deterioration in dysfunctional behaviors, while even showing improvements in some, suggesting that trauma-focused treatment preceded by skills building was not deleterious to this population. Hence, the dissemination of effective interventions such as D-CPT should be fostered, whilst the concerns of the therapists regarding exposure-based components need to be addressed during appropriate training. Nevertheless, further studies with momentary assessment, extended measurement methods, a control group and larger sample sizes are needed to confirm our preliminary findings.
Trial registration: The trial was registered at the German Clinical Trial Registry (GCTR), DRKS00004787, 18 March 2013, https://www.drks.de/DRKS00004787.
