Idiographic Interrater Reliability Measures for Intensive Longitudinal Multirater Data
No full textInterrater reliability plays a crucial role in various areas of psychology. In this article, we propose a multilevel latent time series model for intensive longitudinal data with structurally different raters (e.g., self-reports and partner reports). The new MR-MLTS model enables researchers to estimate idiographic (person-specific) rater consistency coefficients at both the dynamic and momentary level. Additionally, the model allows rater consistency coefficients to be linked to external explanatory or outcome variables. It can be implemented in Mplus as well as in the newly developed R package mlts. We illustrate the model using data from an intensive longitudinal multirater study involving 100 heterosexual couples (200 individuals) assessed across 86 time points. Our findings show that relationship duration and partner cognitive resources positively predict momentary, but not dynamic, rater consistency. Results from a simulation study indicate that the number of time points is critical for accurately estimating idiographic rater consistency coefficients, whereas the number of participants is important for accurately recovering the random effect variances. We discuss advantages, limitations, and future extensions of the MR-MLTS model.notReviewedothe
The effect of depression and hopelessness on suicidal risk in young people: The mediating role of impulsivity
No full textBackground: Previous studies have documented that depression and hopelessness predict higher suicide risk in young people. However, the psychological mechanisms that may mediate these associations are unknown. The aim of this study was to analyze the effects of depression, hopelessness, and impulsivity on suicidal attempts and risk, and to explore the mediating role of impulsivity in these associations. Method: A total of 1,645 young people participated with a mean age of 21.604 years (SD = 3.22) (68.8% female and 31.2% male). A sociodemographic form was applied to explore suicide attempts in the last year (SA), the Plutchik Suicide Risk (SR), Beck Hopelessness (BHS), Barratt Impulsivity (BIS), and Beck Depression Inventory (BDI) scales. Direct correlations were found among BHS, BDI, BIS, SA, and SR. Results: The binary regression model showed that the variables BHS, BDI, and BIS explained between 33% and 49% of the variance of suicidal risk and 16% of the variance of suicide attempts. Structural equation analysis showed that impulsivity mediated the associations between depression, hopelessness, and suicidal risk, on the one hand, and mediated the associations between depression and suicide attempt, on the other hand, whose total direct and indirect effects were statistically significant. Conclusion: The findings emphasize the importance of impulsivity as the mechanism influencing interactions between mood indicators and suicidal behavior in young populations.peerReviewedpublishedVersio
KLARpsy-Text: Wie hängt die Neigung, Situationen verzerrt zu deuten, mit Verfolgungswahn zusammen?
No full textKLARpsy-Texte sind kurze, lai:innengerechte, allgemeinverständliche und richtlinienbasierte Zusammenfassungen psychologischer Übersichtsarbeiten. Dieser KLARpsy-Text hat den Titel “Wie hängt die Neigung, Situationen verzerrt zu deuten, mit Verfolgungswahn zusammen?”. Er wurde von Mitarbeitenden des Leibniz-Instituts für Psychologie verfasst. Eine anonyme testlesende Person war beteiligt. Der KLARpsy-Text befasst sich mit folgenden Inhalten: Die Neigung zu Verfolgungswahn kommt in unterschiedlichem Ausmaß in der Allgemeinbevölkerung vor. Sie kann durch belastende Lebensereignisse und verzerrtes Denken verstärkt werden. Besonders wichtig ist dabei eine Form des verzerrten Denkens, die Forschende als Interpretationsbias bezeichnen. Hierbei neigen manche Menschen dazu, mehrdeutige Situationen verzerrt negativ oder sogar bedrohlich zu deuten. Zum Beispiel glauben sie dann, dass Personen, die sich in der Nähe unterhalten, schlecht über sie reden. Mit ihrer Übersichtsarbeit wollten die Forschenden herausfinden: 1) Wie stark hängen die Neigungen zu einer verzerrten Deutung und zu Verfolgungswahn insgesamt zusammen? 2) Wie groß ist der Zusammenhang bei Menschen mit psychischen Störungen, die häufig mit Verfolgungswahn einhergehen? Die Neigung, Situationen verzerrt negativ oder bedrohlich zu deuten, hängt mit der Neigung zu Verfolgungswahn zusammen. Personen, die dazu neigen, Situationen negativ oder bedrohlich zu deuten, neigen eher dazu, sich verfolgt zu fühlen. Das gilt sowohl für psychisch gesunde Personen als auch für Personen, die an einer Psychose oder Schizophrenie leiden.https://klarpsy.de/hintergrundunknownunknow

The readability of the non-binary gender star in German: Evidence from a lexical decision task
No full textThe non-binary gender star in German (e.g., Radfahrer*in - cyclist) is intended to inclusively address all genders, that is, persons identifying beyond a female-male dichotomy, as well as women and men. Critics of this gender-fair form claim that, because it is not in line with German orthography, it impedes the readability of texts. Experimental research on this claim is still scarce. Because word recognition is a crucial component of the reading process, we developed a lexical decision task to investigate lexical access to role nouns in star form with a student (Experiment 1: 97 participants, 18–29 years) and a non-student sample (Experiment 2: 80 participants, 30–80 years), thus taking interindividual differences into account. Our results are promising for proponents of the star form: First, we found that less than 3% of all participants rejected star nouns as German words. Second, amongst the remaining participants, students accepted star nouns as quickly and as often as feminine and masculine forms. In contrast, non-students accepted star nouns more slowly and less often. However, the non-students’ initial difficulties in lexical access reflected in slower reaction times were overcome quickly over the course of the experiment thus suggesting that the readability of the gender star is a matter of familiarity and practice.peerReviewedpublishedVersio

The psychometric properties of the Polish-language version of the Mathematical Resilience Scale
No full textThis study aims to present the psychometric properties of the Polish language version of the Mathematical Resilience Scale (MRS; Kooken et al., 2016), established in a sample of 443 adults. We confirmed the first-order three-factor structure (Value, Struggle, Growth) with the second-order factor (Total Mathematical Resilience) of the MRS and its measurement invariance across gender and field of study and profession. We also confirmed the validity of the scale: negative correlations were found between MRS scores and math anxiety, math avoidance, intellectual helplessness in mathematics; positive correlations were found between MRS scores, mathematical achievement, math learning motivation; no relationship or weak correlations were found between MRS scores, intellectual helplessness in Polish language, Polish language grades obtained in high school. Finally, we observed gender and study and profession differences in some of the MRS scores. However, further research is needed on the nature of mathematical resilience, especially to establish its relationship with general resilience.peerReviewedpublishedVersio
Code for: Leaving the Catholic Church: Cross-sectional and Longitudinal Predictors of Leaving Intentions
No full textCode for: Pummerer, L., Reinhardt, C., & Nielsen, M. (2025). Leaving the Catholic Church: Cross-Sectional and Longitudinal Predictors of Leaving Intentions. The International Journal for the Psychology of Religion, 1–18. https://doi.org/10.1080/10508619.2025.2553408What predicts whether people are likely to leave the Catholic Church? We examine the role of different identification aspects and their interaction with acceptance of authority, possibility for change, and reputation of the Church in society. In a cross-sectional (N = 583) and longitudinal study with random intercept (N = 271) we find that specifically lower scores on the identification aspects of solidarity, satisfaction, and centrality predict leaving intentions. Cross-sectionally, the relationship between identification and leaving intentions is moderated by acceptance of authority, possibility for change, and reputation (NRange = 580 – 583). However, this moderation is not confirmed in longitudinal cross-lagged panel analyses (N = 263/195). Overall, findings point to self-investment aspects of identification as a crucial factor in predicting leaving intentions and emphasize the importance of assessing identification with the Church multi-dimensionally and longitudinally.unknownunknow
Stability of network models linking personality to conspiracy mentality before and during the COVID-19 pandemic [Author Accepted Manuscript]
No full textDiscussions about potential intervention targets, antecedents, and consequences of conspiracy beliefs often rely on comparing bivariate correlations, which can mask intricate patterns. Therefore, the present study adopts a multivariate network approach to gain nuanced insights into the relationships between personality variables and conspiracy mentality. Established and less-studied correlates of conspiracy mentality (i.e., bedtime procrastination, life satisfaction, locus of control, neuroticism, political cynicism, self-efficacy, and self-esteem) were examined together in network models at the aggregate score level and item level. Notably, network stability was examined across different samples before (N = 403) and during (N = 193) the COVID-19 pandemic. The main findings are: (a) The strength and sign of the relationships were often stable across bivariate and network analyses (e.g., positive relationships between political cynicism and conspiracy mentality); however, there were exceptions, such as an inconsistent link between life satisfaction and conspiracy mentality. (b) While many network relationships and centrality indices were similar before and during the COVID-19 pandemic, some noteworthy exceptions indicate that interventions targeting implausible conspiracy beliefs may benefit from tailoring to external circumstances. (c) Certain influential network elements were identified that could inform future interventions (e.g., increasing politicians' transparency and accountability).reviewedacceptedVersio
The Mediating Role of Sleep Quality in the Relationship Between Academic Stress and Test Anxiety among University Undergraduates
No full textTest anxiety is a prevalent issue that affects university undergraduates globally. Test anxiety and academic stress is known to be related, however, the possible mechanisms behind this association need to be uncovered. This study aims to ascertain if the relationship between test anxiety and academic stress is mediated by sleep quality among University of Ibadan undergraduates. A cross-sectional survey design was adopted to select 360 students (male 176 and female 184), aged 16 to 30 years (M = 20.12, SD = 2.22), utilizing a multi-stage sampling technique. Participants responded to three instruments; Perception of Academic Stress Scale, Test Anxiety Inventory-5, and Sleep Quality Scale. Descriptive and inferential statistics were performed by using SPSS and AMOS (SEM). The SEM analysis showed a good fit of the data (χ2 = 11.947, df = 5, p < .05), RMSEA = 0.062 (90% CI [0.02, 0.10]), GFI = 0.99; CFI = 0.95; TLI = 0.93; SRMR=0.05, to the hypothesized model. Academic stress and sleep quality explained 24% of the variance in test anxiety. Academic stress and sleep quality had an inverse relationship (β = -0.18, p <.05) while sleep quality negatively predicted test anxiety (β = -0.21, p < .01). A strong direct effect (β = 0.37, p < .01) and low indirect effect (β = 0.04, 95% CI [-0.16, -0.075]) of academic stress on test anxiety partially mediated by sleep quality were observed. Test anxiety is influenced directly and indirectly by academic stress through sleep quality. Prioritizing sleep could help improve overall mood among students with test anxiety.peerReviewedpublishedVersio
