The present diary study was conducted for the purpose of bridging and integrating empirical research on the antecedents and consequences of work-related ruminative processes in the evening. Based on the control theory, unfinished tasks and fatigue in the afternoon were considered as antecedents of affective rumination, while vitality was investigated as the outcome observed in the next morning to test for cyclical processes. During a 5-day diary study (including 3 weekdays and the weekend), 74 beginning teachers completed three diary entries per day. A total of 795 diary entries were obtained. Using multilevel structural equation modeling, the study supported that both fatigue and unfinished tasks explained unique shares of variance of affective rumination in the evening at the between- and within-person levels. Furthermore, affective rumination mediated the relationship between unfinished tasks and vitality as well as fatigue and vitality. However, this only held true at the between- and not the within-person level, as neither affective rumination nor fatigue and unfinished tasks predicted the following morning’s vitality at this level. The results offer insights into the antecedents of affective rumination and add to extant research on the negative consequences of affective rumination considering vitality as an outcome.
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...
Über zwei Drittel aller Menschen erleben in ihrem Leben mindestens ein traumatisches Ereignis (Kessler et al., 2017). Gerade nach interpersonellen Traumatisierungen ist die Rate der Betroffenen, welche eine posttraumatische Belastungsstörung (PTBS) entwickeln, sehr hoch (z. B. ca. 50% nach sexuellem Missbrauch; Hauffa et al., 2011). In der Vergangenheit wurden Angst- und Ohnmachtsgefühle als zentrale der PTBS zu Grunde liegende Emotionen aufgefasst (Foa & Kozak, 1986). Neuere Forschungsbefunde legen jedoch nahe, dass traumabezogene Schuld- und Schamgefühle auch eine wichtige Rolle bei der Entstehung und Aufrechterhaltung der PTBS spielen (z. B. Badour et al., 2017). Dabei leiden besonders Betroffene von interpersonellen Gewalterfahrungen unter diesen Gefühlen (z. B. Badour et al., 2017).
Im Hinblick auf die psychotherapeutische Behandlung der PTBS haben sich traumafokussierte Verfahren als wirksam erwiesen (z. B. Lewis et al., 2020). Hohe Drop-out (z. B. Swift & Greenberg, 2014) und Nonresponse Raten (Fonzo et al., 2020) geben jedoch Hinweise darauf, dass nicht allen PTBS Patient*innen mit diesen Verfahren ausreichend geholfen werden kann, wobei insbesondere Patient*innen mit interpersonellen Traumatisierungen weniger gut davon zu profitieren scheinen (z. B. Karatzias et al., 2019). Zudem hat sich gezeigt, dass Schuldgefühle auch nach einer erfolgreichen PTBS Behandlung weiter persistieren (Larsen et al., 2019). Demnach besteht ein Bedarf an alternativen Therapieverfahren für Patient*innen mit interpersonellen Traumatisierungen und/oder Schuld- und Schamgefühlen.
Besonders vielversprechend sind hierbei achtsamkeitsbasierte Interventionen, die bereits in der PTBS Behandlung eine zunehmend bedeutsame Rolle spielen (Hopwood & Schutte, 2017). Eine wichtige Voraussetzung für die weitere Erforschung dieser Interventionen sind valide und reliable Verfahren zur Veränderungsmessung von Achtsamkeit (Isbel et al., 2020). So scheinen bisherige Studien jedoch hauptsächlich fragebogenbasierte Maße zur Erfassung von Veränderungen in Trait-Achtsamkeit eingesetzt zu haben, obwohl diese Interventionen eher auf die Steigerung von State-Achtsamkeit abzielen (Goodman et al., 2017). Darüber hinaus kristallisierten sich methodische Kritikpunkte in Bezug auf die Validität von Fragebögen zur Erfassung von Trait-Achtsamkeit heraus (van Dam et al., 2018). Demgegenüber erfassen Experience-Sampling Ansätze (z. B. Mindful-Breathing Exercise, MBE; Burg & Michalak, 2011) eher Aspekte der State-Achtsamkeit, sind jedoch in klinischen Untersuchungsstichproben bisher kaum untersucht worden. Darauf aufbauend fokussierte die erste Forschungsfrage der Dissertation die Untersuchung der MBE im klinischen Kontext. Ein Hauptbefund der Studie zeigte, dass die MBE bei PTBS Patient*innen hinsichtlich ihres Prädiktionswertes für die PTBS Symptome Übererregung und Intrusionen gegenüber fragebogenbasierter Trait-Achtsamkeit überlegen war. Mögliche Wirkmechanismen achtsamkeitsbasierter Interventionen könnten demnach durch den Einsatz der MBE besonders gut abgebildet werden.
Innerhalb der achtsamkeitsbasierten Interventionen kommt in der Behandlung der PTBS am häufigsten die Mindfulness Based Stress Reduction (MBSR; Kabat-Zinn, 2013) als standardisierte Gruppenintervention zum Einsatz (Boyd et al., 2018). Jedoch scheint die MBSR insbesondere für PTBS Patient*innen mit interpersonellen Traumatisierungen nicht eins-zu-eins anwendbar zu sein (Müller-Engelmann et al., 2017). Buddhistische Metta-Meditationen (dt.: Liebende Güte; Salzberg, 2002) sind vor diesem Hintergrund eine vielversprechende Ergänzung zu achtsamkeitsbasierten Interventionen. Metta-Meditationen zielen darauf ab, sich selbst sowie allen anderen Lebewesen bedingungsloses Wohlwollen und Freundlichkeit entgegen zu bringen (Bodhi, 2010). Metta-Meditationen sind noch weniger gut in der klinischen Forschung etabliert. Erste Befunde deuten jedoch darauf hin, dass sie bei PTBS Patient*innen zu einer Reduktion der PTBS Symptomatik führen können (z. B. Kearney et al., 2021). Folglich wurde im Rahmen der zweiten Forschungsfrage eine neue Intervention entwickelt und evaluiert, welche sich an den Bedürfnissen von PTBS Patient*innen mit interpersonellen Traumatisierungen orientiert. Sie kombiniert kürzere, PTBS spezifische Achtsamkeitsübungen mit angepassten Übungen aus MBSR sowie Metta-Meditationen (= Trauma-MILOKI). Trauma-MILOKI zeigte sich in einer multiplen Baseline Studie wirksam zur Reduktion der PTBS Symptome sowie zur Steigerung des Wohlbefindens.
Ein Wirkmechanismus von Metta-Meditationen ist die Förderung positiver Emotionen sowie des Gefühls sozialer Verbundenheit (Salzberg, 2002), weswegen sie auch besonders gut geeignet scheinen, traumabezogene Schuld- und Schamgefühle zu reduzieren. Darüber hinaus haben sich unter den etablierten Therapieverfahren v. a. kognitive Ansätze zur Reduktion von Schuldgefühlen als wirksam erwiesen (Resick et al., 2008)...
Background: Hebb repetition learning is a form of long-term serial order learning that can occur when sequences of items in an immediate serial recall task are repeated. Repetition improves performance because of the gradual integration of serial order information from short-term memory into a more stable long-term memory trace.
Aims: The current study assessed whether adolescents with non-specific intellectual disabilities showed Hebb repetition effects, and if their magnitude was equivalent to those of children with typical development, matched for mental age.
Methods: Two immediate serial recall Hebb repetition learning tasks using verbal and visuospatial materials were presented to 47 adolescents with intellectual disabilities (11–15 years) and 47 individually mental age-matched children with typical development (4–10 years).
Results: Both groups showed Hebb repetition learning effects of similar magnitude, albeit with some reservations. Evidence for Hebb repetition learning was found for both verbal and visuospatial materials; for our measure of Hebb learning the effects were larger for verbal than visuospatial materials.
Conclusions: The findings suggested that adolescents with intellectual disabilities may show implicit long-term serial-order learning broadly commensurate with mental age level. The benefits of using repetition in educational contexts for adolescents with intellectual disabilities are considered.
Since 2020, the COVID-19 pandemic had an impact on education worldwide. There is increased discussion of possible negative effects on students’ learning outcomes and the need for targeted support. We examined fourth graders’ reading achievement based on a school panel study, representative on the student level, with N = 111 elementary schools in Germany (total: N = 4,290 students, age: 9–10 years). The students were tested with the Progress in International Reading Literacy Study instruments in 2016 and 2021. The analysis focused on (1) total average differences in reading achievement between 2016 and 2021, (2) average differences controlling for student composition, and (3) changes in achievement gaps between student subgroups (i.e., immigration background, socio-cultural capital, and gender). The methodological approach met international standards for the analysis of large-scale assessments (i.e., multiple multi-level imputation, plausible values, and clustered mixed-effect regression). The results showed a substantial decline in mean reading achievement. The decline corresponds to one-third of a year of learning, even after controlling for changes in student composition. We found no statistically significant changes of achievement gaps between student subgroups, despite numerical tendencies toward a widening of achievement gaps between students with and without immigration background. It is likely that this sharp achievement decline was related to the COVID-19 pandemic. The findings are discussed in terms of further research needs, practical implications for educating current student cohorts, and educational policy decisions regarding actions in crises such as the COVID-19 pandemic.
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.
Social pain is an emotional reaction to social exclusion which has been widely investigated in experimental settings. We developed the Social Pain Questionnaire (SPQ) and examined its factor structure, reliability, and construct validity. We constructed a 46-item pool that covered a broad range of situations related to social pain. Using three different subsamples (Online convenience sample: n = 623, Representative sample: n = 2531, Clinical sample of outpatients seeking psychotherapy: n = 270) we reduced the item pool to 10 items for the final SPQ scale, paying particular attention to content validity and factorial structure. Convergent, divergent and discriminant validity were assessed using standardized measures of related constructs and group differences. For the final 10-item version, a good factorial structure and reliability were found. Convergent validity was supported by correlations with related instruments of interpersonal sensitivity, attachment styles, depression and social anxiety. The representative and clinical sample differed significantly in social pain. The SPQ is an economic self-report measure with solid psychometric properties. Our data support the factorial, construct and convergent validity. The SPQ can be used to clarify the role of social pain in mental disorders and to incorporate interventions targeted towards social pain in psychotherapeutic settings.
Im Bobsport herrscht Konsens, dass die Startphase von zentraler Bedeutung für eine gute Endzeit ist. Dennoch hat sich die Sportwissenschaft mit der Frage, wie der Bobstart gelingt, bis dato kaum auseinandergesetzt. Der Beitrag holt dies in Form einer leibphänomenologischen Analyse der Startphase im Viererbob nach, indem er sein Augenmerk sowohl auf die leibliche Kommunikation der Athleten untereinander als auch zwischen ihnen und ihrem Sportgerät richtet. Theoretisches Fundament hierfür ist die Leibphänomenologie von Hermann Schmitz, empirische Grundlage sind problemzentrierte Interviews mit acht Kaderathleten des Bob- und Schlittenverbands für Deutschland (BSD). Zentrales Ergebnis der Untersuchung ist erstens, dass für das Gelingen des Viererbobstarts vor allem die antagonistisch-einseitige Einleibung der Athleten untereinander wie auch der Athleten mit dem Bob bedeutsam ist. Zweitens erweist sich die solidarische Einleibung der Athleten als wichtige Bedingung und gleichermaßen spürbarer Ausdruck eines gelungenen Viererbobstarts. Der Text präsentiert damit einen vollkommen neuen Blick auf den Bobsport. Mit seinem theoretisch-konzeptionellen Fokus auf leibliche Kommunikation im Sport liefert er darüber hinausgehend einen innovativen Beitrag zur phänomenologischen Sportforschung, wie er generell die fruchtbare Verbindung von Philosophie und empirischer Sportwissenschaft belegt.
Individualization can be defined as the adaptation of instructional parameters to relevant characteristics of a specific learner. This definition raises several questions, however: Which characteristics are actually relevant? Which parameters of instruction need to be adjusted, and in which way, to positively interact with those characteristics? In a classroom context, additional questions arise: how can information about the relevant learner characteristics be delivered to the teacher? How can individualized instruction be delivered to each learner in a context that has originally been designed for whole-class instruction? By focusing on the measurement and modelling of learner characteristics and instructional adaptations, this dissertation aims to provide an insight into each of these issues.
This dissertation is divided into two parts. The first part is concerned with the theoretical (Paper 1) and statistical (Paper 2) modeling of learner characteristics in the context of individualized instruction. The second part is concerned with the measurement (Paper 3) and implementation (Paper 4) of individualized instruction in the classroom context.
Paper 1 summarizes existing research on individualization from different research traditions. From this summary I derive the need for a dynamic conceptualization of learner characteristics (acknowledging that learners change during and in interaction with the learning process) and synthesize a dynamic framework that details the opportunities for individualization on three different timescales. Paper 2 reports results from an exploratory study that investigated the potential benefits of utilizing person-centered analysis for the assessment of multivariate learner prerequisites and their interaction with instruction. We found that latent profiles over several reading related abilities could explain differential effectiveness of self-reported teaching foci in German third grade reading lessons. These findings indicate not just a need for stronger individualization of teaching but also an advantage of multivariate conceptualizations of learner characteristics. Additionally, they show the utility of person-centered approaches for the investigation of such multivariate learner characteristics and their interaction with instruction.
In the second part, I investigate possible approaches to the implementation and measurement of individualization in a classroom context. Paper 3 investigates whether teacher-, student- and observer perspectives converge when rating the amount of individualization present in regular classroom instruction. We found considerable agreement between the perspectives, indicating a common understanding of the construct at the classroom level as well as providing some evidence for the validity of the used measurement instruments. Paper 4 replicates findings concerning the effectiveness of formative assessment procedures for fostering reading education, supplemented by a moderator analysis showing that only children with low performance at the beginning of the school-year profited from its implementation. This indicates that the information provided by formative assessment procedures helps teachers to identify struggling readers but does not seem to be utilized for adapting instruction to specific deficits of average or high performing children.
In sum, this dissertation contributes to research on individualized instruction by demonstrating necessary conditions for its effectiveness. It posits the need for a dynamic conceptualization of learner characteristics, demonstrates the advantage of multivariate learner profiles, and points out ways towards the successful implementation of individualized instruction in the classroom.
Recent research on the dynamics between attentional and memory processes have outlined the idea that applying control in a conflicting situation directly leads to enhanced episodic memory of the processed information. However, in spite of a small subset of studies supporting this claim, the majority of the evidence in the field seems to support the opposite pattern. In this study, we used a face–word Stroop task to enforce different control modes either from trial to trial or in an item-specific manner. Both manipulations of congruency proved to be effective in making participants’ responses to conflicting stimuli more efficient over time by applying a trial-specific control mode. However, these manipulations had no impact on memory performance on a surprise recognition memory test. To our knowledge, this is the first attempt at measuring the memory consequences of the application of specific control modes at the trial level. The results reported here call for caution and possibly reconceptualization of the relationship between cognitive control and memory.
Measuring teaching cross-culturally - the issue of measurement invariance and sources of bias
(2021)
Im Kontext der Globalisierung nimmt das Interesse daran, Unterricht vergleichend zwischen Bildungssystemen der ganzen Welt zu untersuchen, kontinuierlich zu (Paine et al., 2016). Unterricht ist einer der stärksten Prädiktoren für Lernergebnisse von Schülerinnen und Schülern (Hattie, 2009). Folglich bieten internationale Vergleiche die einmalige Möglichkeit von besonders erfolgreichen Bildungssystemen zu lernen und geben Auskunft über die Generalisierbarkeit beziehungsweise über die kulturellen Variationen von Unterricht und dessen Wirksamkeit. Gleichzeitig sind sie richtungsweisend für bildungspolitische Entscheidungen (Klieme, 2020). Zur Erfassung von Unterrichtsmerkmalen aus der Perspektive der beteiligten Lehrkräfte und Schülerinnen und Schüler werden häufig Fragebögen in internationalen Schulleistungsstudien eingesetzt. Erste empirische Befunde weisen jedoch daraufhin, dass die Fragebogenskalen oftmals nicht messinvariant sind (z.B. Desa, 2014; He & Kubacka, 2015; Nilsen & Gustafsson, 2016). Das bedeutet, dass Unterschiede in den Messwerten zwischen Bildungssystemen nicht automatisch genuine Unterschiede im gemessenen Konstrukt, wie beispielsweise Unterschiede in der Klassenführung, reflektieren. Stattdessen entstehen diese teilweise durch nicht intendierte kulturelle Variationen im Antwortprozess (Bias), beispielsweise durch kulturelle Unterschiede in der Bedeutung der Items zur Messung von Klassenführung oder durch kulturspezifische Antworttendenzen (van de Vijver & Leung, 1997). Eine fehlende Messinvarianz hat folgenreiche Konsequenzen, da valide (Mittelwerts-)Vergleiche von Unterrichtsmerkmalen zwischen Bildungssystemen nicht möglich sind und somit die umfangreichen Datensätze internationaler Studien nicht ausgeschöpft werden können (Davidov et al., 2018a). Dennoch mangelt es in der international vergleichenden Bildungsforschung bisher an empirischen Studien, die mit fortgeschrittenen Analysemethoden die Messinvarianz von Unterrichtsmerkmalen prüfen, sowie an empirisch-fundierten Erkenntnissen zu den Ursachen der oftmals fehlenden Invarianz. Mit einer Kombination aus quantitativen und qualitativen Methoden widmet sich die vorliegende Dissertation in drei Beiträgen der Aufarbeitung dieser Forschungslücke. Sie konzentriert sich auf Fragebogenskalen zur Messung von zwei generischen Unterrichtsmerkmalen aus der Perspektive von Schülerinnen und Schülern, der Unterrichtsqualität mit den Dimensionen Klassenführung, konstruktive Unterstützung und kognitive Aktivierung und den Unterrichtsmethoden mit den Dimensionen lehrerzentrierte und schülerzentrierte Methoden und Methoden des Assessments.
Beitrag I prüft die Messinvarianz von PISA Skalen zur Erfassung der drei Basisdimensionen der Unterrichtsqualität zwischen 15 Bildungssystemen. Zusätzlich wird untersucht, ob die kulturelle Ähnlichkeit (operationalisiert als ähnliche oder identische Sprache) der Bildungssysteme einen Einfluss auf das Ausmaß der Messinvarianz besitzt. Da die Modellannahmen der häufig eingesetzten konfirmatorischen Faktorenanalyse zunehmend als zu strikt für Messinvarianzprüfungen im interkulturellen Kontext kritisiert werden (Rutkowski & Svetina, 2014), wird mit Alignment (Asparouhov & Muthén, 2014) eine flexiblere und angemessenere Methode verwendet. Dennoch erreichen die drei Basisdimensionen nur metrische (identische Faktorenladungen) und nicht skalare Invarianz (identische Intercepts) zwischen den 15 Bildungssystemen. Folglich sind valide Vergleiche von Mittelwertsunterschieden in der Unterrichtsqualität zwischen den 15 Bildungssystemen nicht möglich. Innerhalb der fünf Cluster, bestehend aus jeweils drei Bildungssystemen mit ähnlicher oder identischer Sprache, wird im Gegensatz dazu skalare Invarianz bestätigt. Die Ergebnisse aus Beitrag I legen nahe, dass die untersuchten Fragebogenskalen zur Messung von Unterrichtsqualität unterschiedlich zwischen Bildungssystemen funktionieren. Eine höhere Vergleichbarkeit scheint jedoch mit einer kulturellen und sprachlichen Ähnlichkeit der Befragten einherzugehen. Wird diese Ähnlichkeit bei der Analyse berücksichtigt, sind valide Vergleiche von Mittelwertsunterschieden für eine Teilmenge an Bildungssystemen mit invarianter Messung möglich.
Beitrag II knüpft an Ergebnisse aus Beitrag I an und untersucht potenzielle Ursachen der fehlenden Invarianz. Der Fokus liegt auf kulturellen Variationen im Antwortprozess, die zu einer eingeschränkten Datenvergleichbarkeit führen können (z.B. Schwarz et al., 2010). Beitrag II konzentriert sich auf die erste und zweite Stufe des Antwortprozesses, der Item-Interpretation und der Assoziation des Item-Inhaltes mit persönlichen Erfahrungen (Tourangeau, 1984). Mit Hilfe von kognitiven Interviews wird untersucht, wie Schülerinnen und Schüler aus China (Shanghai) und Deutschland PISA Items zur Messung konstruktiver Unterstützung interpretieren und welche Unterrichtserfahrungen sie mit den Items assoziieren. Die Ergebnisse der strukturierenden qualitativen Inhaltanalyse nach Kuckartz (2018) zeigen zwar, dass sowohl chinesische als auch deutsche Schülerinnen und Schüler die Items mehrheitlich mit Unterrichtsmethoden assoziieren, die zur Kompetenzunterstützung beitragen (beispielsweise Methoden zur Beseitigung von Verständnisproblemen). Es zeigen sich jedoch auch deutliche interpretative Variationen, sowohl für statistisch nicht messinvariante (nicht vergleichbare) Items als auch für messinvariante (vergleichbare) Items. Diese können zum einen auf Eigenschaften der Messung zurückgeführt werden. Hierzu zählt eine unterschiedliche Übersetzung des Terms Lernen (in Deutschland Lernfortschritt in China Lernstand). Zudem finden sich Hinweise, dass komplexe und uneindeutige Itemformulierungen mehr Spielraum für kulturspezifische Interpretationen zulassen. Die zweite Ursache der interpretativen Variationen ist ein unterschiedliches Verständnis von konstruktiver Unterstützung, das durch kulturelle Unterschiede in der Unterrichtsgestaltung und -zielsetzung erklärt werden kann (Leung, 2001). Neben der Kompetenzunterstützung assoziieren die deutschen Schülerinnen und Schüler die Items mehrheitlich mit Methoden zur Unterstützung ihrer Autonomie und ihres sozial-emotionalen Erlebens im Unterricht, wohingegen die chinesischen Schülerinnen und Schüler die Items mehrheitlich mit Methoden zur Unterstützung ihrer akademischen Produktivität (z.B. ihrer Aufmerksamkeit) assoziieren. Die Ergebnisse aus Beitrag II legen nahe, dass die Interpretation von Fragebogenitems variieren kann, je nach dem in welchem kulturellen Kontext die Frage gestellt wird. Sie betonen zudem, dass quantitative und qualitative Methoden miteinander kombiniert werden sollten, um verlässliche Information über die interkulturelle Vergleichbarkeit von Fragebogenitems zu erhalten ...
Motor imagery is conceptualized as an internal simulation that uses motor-related parts of the brain as its substrate. Many studies have investigated this sharing of common neural resources between the two modalities of motor imagery and motor execution. They have shown overlapping but not identical activation patterns that thereby result in a modality-specific neural signature. However, it is not clear how far this neural signature depends on whether the imagined action has previously been practiced physically or only imagined. The present study aims to disentangle whether the neural imprint of an imagined manual pointing sequence within cortical and subcortical motor areas is determined by the nature of this prior practice modality. Each participant practiced two sequences physically, practiced two other sequences mentally, and did a behavioural pre-test without any further practice on a third pair of sequences. After a two-week practice intervention, participants underwent fMRI scans while imagining all six sequences. Behavioural data demonstrated practice-related effects as well as very good compliance with instructions. Functional MRI data confirmed the previously known motor imagery network. Crucially, we found that mental and physical practice left a modality-specific footprint during mental motor imagery. In particular, activation within the right posterior cerebellum was stronger when the imagined sequence had previously been practiced physically. We conclude that cerebellar activity is shaped specifically by the nature of the prior practice modality.
Background: Diet and physical activity (PA) have a major impact on physical and mental health. However, there is a lack of effective strategies for sustaining these health-protective behaviors. A shift to a microtemporal, within-person approach is needed to capture dynamic processes underlying eating behavior and PA, as they change rapidly across minutes or hours and differ among individuals. However, a tool that captures these microtemporal, within-person processes in daily life is currently not present.
Objective: The APPetite-mobile-app is developed for the ecological momentary assessment of microtemporal, within-person processes of complex dietary intake, objectively recorded PA, and related factors. This study aims to evaluate the feasibility and usability of the APPetite-mobile-app and the validity of the incorporated APPetite-food record.
Methods: The APPetite-mobile-app captures dietary intake event-contingently through a food record, captures PA continuously through accelerometers, and captures related factors (eg, stress) signal-contingently through 8 prompts per day. Empirical data on feasibility (n=157), usability (n=84), and validity (n=44) were collected within the Eat2beNICE-APPetite-study. Feasibility and usability were examined in healthy participants and psychiatric patients. The relative validity of the APPetite-food record was assessed with a subgroup of healthy participants by using a counterbalanced crossover design. The reference method was a 24-hour recall. In addition, the energy intake was compared with the total energy expenditure estimated from accelerometry.
Results: Good feasibility, with compliance rates above 80% for prompts and the accelerometer, as well as reasonable average response and recording durations (prompt: 2.04 min; food record per day: 17.66 min) and latencies (prompts: 3.16 min; food record: 58.35 min) were found. Usability was rated as moderate, with a score of 61.9 of 100 on the System Usability Scale. The evaluation of validity identified large differences in energy and macronutrient intake between the two methods at the group and individual levels. The APPetite-food record captured higher dietary intakes, indicating a lower level of underreporting, compared with the 24-hour recall. Energy intake was assessed fairly accurately by the APPetite-food record at the group level on 2 of 3 days when compared with total energy expenditure. The comparison with mean total energy expenditure (2417.8 kcal, SD 410) showed that the 24-hour recall (1909.2 kcal, SD 478.8) underestimated habitual energy intake to a larger degree than the APPetite-food record (2146.4 kcal, SD 574.5).
Conclusions: The APPetite-mobile-app is a promising tool for capturing microtemporal, within-person processes of diet, PA, and related factors in real time or near real time and is, to the best of our knowledge, the first of its kind. First evidence supports the good feasibility and moderate usability of the APPetite-mobile-app and the validity of the APPetite-food record. Future findings in this context will build the foundation for the development of personalized lifestyle modification interventions, such as just-in-time adaptive interventions.
The COVID-19 pandemic has called worldwide for strong governmental measures to contain its spread, associated with considerable psychological distress. This study aimed at screening a convenience sample in Germany during lockdown for perceived vulnerability to disease, knowledge about COVID-19, symptoms of depression and anxiety, and behavioral responses. In an online survey, 1358 participants completed the perceived vulnerability to disease scale (PVD), the Patient Health Questionnaire (PHQ-4), and questionnaires on knowledge about COVID-19 and self-perceived change in behaviors in response to COVID-19. Lower and upper quartiles of the PVD were used to classify individuals into low and high PVD. A confirmatory factor analysis supported three factors representing risk, preventive and adaptive behavior as behavioral responses to COVID-19 lockdown. A structural equation model showed that the score of the knowledge scale significantly predicted the self-reported increase in adaptive and preventive behavior. The score in the PVD-subscale Perceived Infectability predicted a self-reported increase in preventive behavior, whereas the Germ Aversion score predicted a self-reported increase in preventive and a decrease in risk behavior. The score in PHQ-4 predicted a higher score in the perceived infectability and germ aversion subscales, and a self-reported decrease in adaptive behavior. Low-, medium- and high-PVD groups reported distinct patterns of behavior, knowledge, and mental health symptoms. This study shows that perceived vulnerability to disease is closely linked to preventive behaviors and may enhance adaptation to COVID-19 pandemic.
This systematic review investigated how successful children/adolescents with poor literacy skills learn a foreign language compared with their peers with typical literacy skills. Moreover, we explored whether specific characteristics related to participants, foreign language instruction, and assessment moderated scores on foreign language tests in this population. Overall, 16 studies with a total of 968 participants (poor reader/spellers: n = 404; control participants: n = 564) met eligibility criteria. Only studies focusing on English as a foreign language were available. Available data allowed for meta-analyses on 10 different measures of foreign language attainment. In addition to standard mean differences (SMDs), we computed natural logarithms of the ratio of coefficients of variation (CVRs) to capture individual variability between participant groups. Significant between-study heterogeneity, which could not be explained by moderator analyses, limited the interpretation of results. Although children/adolescents with poor literacy skills on average showed lower scores on foreign language phonological awareness, letter knowledge, and reading comprehension measures, their performance varied significantly more than that of control participants. Thus, it remains unclear to what extent group differences between the foreign language scores of children/adolescents with poor and typical literacy skills are representative of individual poor readers/spellers. Taken together, our results indicate that foreign language skills in children/adolescents with poor literacy skills are highly variable. We discuss the limitations of past research that can guide future steps toward a better understanding of individual differences in foreign language attainment of children/adolescents with poor literacy skills.
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.
Children often perform worse than adults on tasks that require focused attention. While this is commonly regarded as a sign of incomplete cognitive development, a broader attentional focus could also endow children with the ability to find novel solutions to a given task. To test this idea, we investigated children’s ability to discover and use novel aspects of the environment that allowed them to improve their decision-making strategy. Participants were given a simple choice task in which the possibility of strategy improvement was neither mentioned by instructions nor encouraged by explicit error feedback. Among 47 children (8—10 years of age) who were instructed to perform the choice task across two experiments, 27.5% showed a full strategy change. This closely matched the proportion of adults who had the same insight (28.2% of n = 39). The amount of erroneous choices, working memory capacity and inhibitory control, in contrast, indicated substantial disadvantages of children in task execution and cognitive control. A task difficulty manipulation did not affect the results. The stark contrast between age-differences in different aspects of cognitive performance might offer a unique opportunity for educators in fostering learning in children.
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.
