Individuals are expected to mature with increasing age, but it is not yet fully understood which factors contribute to this maturation process. Using data of a representative sample of Germans (N = 14,718) who gave information about their Big Five personality traits twice over a period of 4 years, we identified satisfaction with life, which was reported yearly, as an important variable for explaining ...
Purpose: To describe the major findings in the literature regarding associations between biological and genetic factors and social functioning, paying special attention to: (1) heritability studies on social functioning and related concepts; (2) hypothesized biological pathways and genetic variants that could be involved in social functioning, and (3) the implications of these results for quality-of-life ...
Does personality change across the entire life course, and are those changes due to intrinsic maturation or major life experiences? This longitudinal study investigated changes in the mean levels and rank order of the Big Five personality traits in a heterogeneous sample of 14,718 Germans across all of adulthood. Latent change and latent moderated regression models provided four main findings: First, ...
Objectives - Taking a cross-national comparative perspective, we investigate linkages between volunteer work, informal helping, and caring among Europeans aged 50 or older: Is the relationship between these activities characterized by complementarity or by substitution? Is there evidence for the existence of (unobserved) personality traits that foster engagement independent of a specific activity? ...
We examined measurement invariance and age-related robustness of a short 15-item Big Five Inventory (BFI-S) of personality dimensions, which is well suited for applications in large-scale multidisciplinary surveys. The BFI-S was assessed in three different interviewing conditions: computer-assisted or paper-assisted face-to-face interviewing, computer-assisted telephone interviewing, and a self-administered ...
Numerous studies proved that people tend to select partners that are similar to them with regard to many social and psychological variables. Even though this effect was also found for personality, results are inconsistent and reveal convergence coefficients ranging from negative over zero- to positive correlations. The present study thus aims to investigate personality congruence between spouses and ...
We provide the first joint evidence on the relationship between individuals' cognitive abilities, their personality and earnings for Germany. Using data from the German Socio-Economic Panel Study, we employ scores from an ultra-short IQ-test and a set of measures of personality traits, namely locus of control, reciprocity and all basic items from the Five Factor Personality Inventory. Our estimates ...
This paper empirically analyzes whether the character-based approach, which focuses on the personality structure and the human capital of business founders, allows prediction of entrepreneurial success. A unique data set is used consisting of 414 persons whose personal characteristics were analyzed by different methods, namely an one-day assessment center (AC) and a standardized questionnaire, before ...
