Can exposure to arguments pro and contra extraversion affect self-reports of the trait and the attitude toward it?

OBJECTIVE: Changeability of personality over short-term intervals has increasingly become a focus of research. However, the role played by argumentation interventions in short-term variations has scarcely been examined. METHODS: In two experiments (N = 363 and 320), we investigated how processing positive and negative argumentation regarding extraversion (Study 1: watching a lecture; Study 2: elaborating self-invented arguments) affects self-reports on this trait and attitude toward it. The experiments included three waves of measurements with argument manipulation (in favor of or against extraversion) immediately prior to Time 2 (Study 2 also included a control group). RESULTS: Mean-level changes in extraversion across time moments, measured with the longitudinal confirmatory factor analysis, were consistently negligible. Conversely, there were some indications that argumentation about extraversion could have immediate short-term effects on attitudes toward this trait. The random-intercept cross-lagged model showed that rank-order consistency stemmed from a trait-like intercept, which was particularly large for trait extraversion compared with the attitude. The autoregressive and cross-lagged effects of residual within-person variation were consistently small and mostly nonsignificant. CONCLUSION: Our findings suggest that extraversion and the attitude toward it maintained their temporal continuity within 3 months, even under a single exposure to arguments pro and contra this trait.

Big Five Traits as Predictors of a Healthy Lifestyle during the COVID-19 Pandemic: Results of a Russian Cross-Sectional Study.

The healthy lifestyle of people around the world has changed dramatically during the COVID-19 pandemic. The personality risk factors for these processes from around the world remain understudied. This study aimed to examine the associations of the Big Five traits with a healthy lifestyle during the COVID-19 pandemic. In a cross-sectional study, data from 1215 Russian university students were analyzed. Participants completed the Big Five Inventory-10 and Short Multidimensional Inventory Lifestyle Evaluation. The results showed that personality traits predicted many dimensions of a healthy lifestyle during the COVID-19 pandemic. Diet and nutrition were positively predicted by extraversion, agreeableness, and conscientiousness, and it was negatively predicted by neuroticism. Substance abuse was positively predicted by agreeableness and conscientiousness, and it was negatively predicted by extraversion. Physical activity was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Stress management was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Restorative sleep was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Social support for healthy practices was positively predicted by extraversion, agreeableness, and conscientiousness. Environmental exposures were positively predicted by extraversion, and neuroticism was positively and negatively predicted by conscientiousness. Our findings may be useful for further exploration of personality risk factors for healthy practices in challenging life circumstances.

Measurement Invariance and Sex and Age Differences of the Big Five Inventory-2: Evidence From the Russian Version.

The Big Five Inventory-2 (BFI-2) is a recently published 60-item questionnaire that measures personality traits within the five-factor model framework. An important aspect of the BFI-2 is that it measures the traits at both the domain and facet levels and also controls acquiescence bias via the balanced number of true- and false-keyed items across the domains and facets. The current research evaluates factorial measurement invariance of a Russian version of the BFI-2 across sex and age within samples of 1,024 university students (Study 1) and 1,029 Internet users (Study 2). Across these samples, men scored lower on the domains of negative emotionality and agreeableness and slightly higher on extraversion. Sex differences were also obtained on various facets. In the Internet sample, age correlated modestly with several Big Five domains in accordance with the well-documented maturity principle. The newly developed Russian version of BFI-2 showed good reliability and validity across both samples. Moreover, random intercept exploratory factor analyses showed that the BFI-2 displayed a hierarchical five-domain-15-facet structure that demonstrated strict measurement invariance across sex and age.
