Predicting Lifetime Suicide Attempts in a Community Sample of Adolescents Using Machine Learning Algorithms
(2023-04-24)
Suicide is a major global health concern and a prominent cause of death in adolescents. Previous research on suicide prediction has mainly focused on clinical or adult samples. To prevent suicides at an early stage, however, it is important to screen for risk factors in a community sample of adolescents. We compared the accuracy of logistic regressions, elastic net regressions, and gradient boosting machines in predicting suicide attempts by 17-year-olds in the Millennium Cohort Study (N = 7,347), combining a large ...

Psychosocial Interventions for Newly Arrived Adolescent Refugees: A Systematic Review
(2020-02-25)
Adolescent refugees are confronted with multiple developmental, psychological, and social challenges after flight. Psychosocial interventions are therefore necessary to support adolescents during the first period after arrival in a receiving country and to avoid negative long-term consequences. Unfortunately, little is known about the types and the effects of such interventions provided during this time. This systematic review aimed to synthesize research about psychosocial interventions for refugee youth during the ...

Aligning Leader Behaviors With Innovation Requirements Improves Performance: An Experimental Study
(2020-07-07)
In this experiment, the effect of the alignment of leader behaviors with innovation requirements was investigated. A sample of N = 245 students participated in a laboratory experiment. Participants had to address either creativity or implementation requirements within a task and received a leadership manipulation in a video message. Results showed that the alignment of leader behaviors with innovation requirements led to improved performance. These findings contribute to the literature by addressing the specific ...

Comparing the effects of generating questions, testing, and restudying on students' long‐term recall in university learning
(2020-01-21)
We compared the long‐term effects of generating questions by learners with answering questions (i.e., testing) and restudying in the context of a university lecture. In contrast to previous studies, students were not prepared for the learning strategies, learning content was experimentally controlled, and effects on factual and transfer knowledge were examined. Students' overall recall performance after one week profited from generating questions and testing but not from restudying. When analyzing the effects on both ...

Neuorientierung für das Business-Coaching
(2021-08-16)
Ausgangspunkt der folgenden Beiträge ist die Arbeit „Coaching in der zweiten Romantik: Abstieg oder Aufstieg?“ von Böning und Strikker. Drei Autor/innen nehmen Stellung zu den Fragen: Welchen Einfluss kann Coaching auf den gesellschaftlichen und politischen Diskurs nehmen, um sowohl gesamtgesellschaftliche als auch politische Handlungsnotwendigkeiten aufzugreifen und dazu Stellung zu nehmen? Wie gestaltet Coaching organisationsbezogen kulturelle und politische Verhältnisse mit, wie sie die Autoren unter anderem in ...

Mit Sicherheit zu etwas Neuem: Zur Bedeutung psychologischer Sicherheit in der Post-Merger-Integration (PMI)
(2021-08-03)
Zahlreiche Unternehmensfusionen in Deutschland scheitern oder bleiben weit hinter den Erwartungen zurück. Besondere Bedeutung für das Gelingen von Fusionen hat die Gestaltung der Post-Merger-Integration, also die Phase des Zusammenführens der beiden vormals selbstständigen Unternehmen. Das von Amy C. Edmondson entwickelte Konzept der psychologischen Sicherheit könnte hierfür eine wichtige Funktion zur Orientierung und Handlungsleitung erhalten. Die erste Auswertung von Ergebnissen einer qualitativen Befragung von ...

Indicators of Affect Dynamics: Structure, Reliability, and Personality Correlates
(2020-07-21)
Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these might convey little unique information beyond mean level and general variability of emotions. Our study extends the evidence for the construct validity of IADs by investigating ...

Null and Void? Errors in Meta-analysis on Perceptual Disfluency and Recommendations to Improve Meta-analytical Reproducibility
(2021-02-03)
In the 2018 meta-analysis of Educational Psychology Review entitled “Null effects of perceptual disfluency on learning outcomes in a text-based educational context” by Xie, Zhou, and Liu, we identify some errors and inconsistencies in both the methodological approach and the reported results regarding coding and effect sizes. While from a technical point of view the meta-analysis aligns with current meta-analytical guidelines (e.g., PRISMA) and conforms to general meta-analytical requirements (e.g., considering ...

Tests and academic cheating: do learning tasks influence cheating by way of negative evaluations?
(2020-04-27)
Desirable difficulties like tests were often shown to increase long-term learning. However, due to the complexity and difficulty of such tasks, they are also argued to result in negative consequences like stress, anxiety, pressure, frustration, or negative evaluations. In other studies, such consequences were, in turn, often found to increase dishonest behaviour. Hence, the present work tests the assumptions that tests as difficult learning tasks, contrary to reading, lead to more negative evaluations of the learning ...
