Validation and generalizability of machine learning prediction models on attrition in longitudinal studies
(2022-02-07)
Attrition in longitudinal studies is a major threat to the representativeness of the data and the generalizability of the findings. Typical approaches to address systematic nonresponse are either expensive and unsatisfactory (e.g., oversampling) or rely on the unrealistic assumption of data missing at random (e.g., multiple imputation). Thus, models that effectively predict who most likely drops out in subsequent occasions might offer the opportunity to take countermeasures (e.g., incentives). With the current study, ...

Spontaneous inferential processing while reading interleaved expository texts enables learners to discover the underlying regularities
(2020-11-05)
Recent studies on text sequencing found learning advantages of interleaving over blocking in terms of high‐level inferences. We conducted a 2 × 2 × 2 mixed factorial experiment with college students (n = 117) by manipulating text sequence (interleaved vs. blocked) and self‐questioning activity while reading (spontaneous vs. prompted) between subjects and testing delay (immediately vs. 1‐week delay) within subjects. Results revealed that students are spontaneously engaged in self‐questioning and inferential processing ...

Are criminals better lie detectors? Investigating offenders' abilities in the context of deception detection
(2020-10-24)
The present research examined lie detection abilities of a rarely investigated group, namely offenders. Results of the studies conducted thus far indicated a better performance of offenders compared to non‐offenders when discriminating between true and false messages. With two new studies, we aimed at replicating offenders' superior abilities in the context of deception detection. Results of Study 1 (N = 76 males), in contrast, revealed that offenders were significantly worse at accurately classifying true and false ...

Psychische Belastungen bei Müllwerkern – Konsequenzen für die Beratungstätigkeit
(2021-01-26)
Um die psychischen Belastungen von Müllwerkern zu erheben, wurde eine Bestandsaufnahme mit der Berufsgruppe vorgenommen, die Erkenntnisse für die spätere Beratungstätigkeit lieferte. Die Erhebung der Belastungen in Gruppendiskussionen wurde durch eine teilnehmende Beobachtung ergänzt, was einen psychodynamischen Blick auf die Besonderheiten der Organisation rund um den Müllwagen und die Charakteristika der Müllwerker erlaubte. Die Ergebnisse zeigen, dass ein Zusammenhang zwischen den Belastungen und dem beruflichen ...

Development and Validation of the Certainty About Mental States Questionnaire (CAMSQ): A Self-Report Measure of Mentalizing Oneself and Others
(2021-12-14)
The Certainty About Mental States Questionnaire (CAMSQ) is a self-report measure of the perceived capacity to understand mental states of the self and others (i.e., mentalizing). In two studies (total N = 1828), we developed the CAMSQ in both English and German as a two-dimensional measure of Self- and Other-Certainty, investigated associations with other measures of mentalizing, and explored relationships to personality functioning and mental health. The CAMSQ performed well in terms of convergent and discriminant ...

Mapping established psychopathology scales onto the Hierarchical Taxonomy of Psychopathology (HiTOP)
(2022-09-26)
The Hierarchical Taxonomy of Psychopathology (HiTOP) organizes phenotypes of mental disorder based on empirical covariation, offering a comprehensive organizational framework from narrow symptoms to broader patterns of psychopathology. We argue that established self-report measures of psychopathology from the pre-HiTOP era should be systematically integrated into HiTOP to foster cumulative research and further the understanding of psychopathology structure. Hence, in this study, we mapped 92 established psychopathology ...

Close replication of Paul, Lee, and Ashton (2022): Who tells prosocial lies?
(2024-08-03)
Within the present research, we conducted a close replication of Paul et al. (2022), who reported the HEXACO Honesty-Humility trait to be positively correlated with prosocial lies by applying a procedure in which participants should rate a poorly written essay. Consistent with the original study, participants (N = 324) higher in Honesty-Humility and Agreeableness showed more prosocial lying. Because the associations disappeared within a shared regression model, we assume the correlation between Honesty-Humility and ...

Using Monte Carlo Simulation to Forecast the Scientific Utility of Psychological App Studies: A Tutorial
(2024-07-11)
Mobile applications offer a wide range of opportunities for psychological data collection, such as increased ecological validity and greater acceptance by participants compared to traditional laboratory studies. However, app-based psychological data also pose data-analytic challenges because of the complexities introduced by missingness and interdependence of observations. Consequently, researchers must weigh the advantages and disadvantages of app-based data collection to decide on the scientific utility of their ...

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 ...

Measuring maladaptive personality traits with the Structured Clinical Interview for DSM-IV Axis II Screening Questionnaire using a common metrics approach
(2024-03-25)
The classification of personality disorder (PD) is undergoing a paradigm shift in which categorically defined specific PDs are being replaced by dimensionally defined maladaptive trait domains. To bridge the classificatory approaches, this study attempts to use items from the categorical PD model in DSM-IV to measure the maladaptive trait domains described in DSM-5 Section III/ICD-11. A general population sample comprising 1228 participants completed the Screening Questionnaire of the Structured Clinical Interview ...
