RESUMEN

Previous research showed the importance of control beliefs for many life outcomes. The present study examines associations between subjectively perceived work environment and objectively measured work activities at the beginning of midlife as a central developmental phase in the context of work, with control beliefs across the subsequent 20 years. We analyzed four-wave longitudinal data from N = 374 participants (born 1950-1952; Mage baseline = 44 years, SD = 1; 44% women) from the Interdisciplinary Longitudinal Study of Adult Development and Aging within a structural equation modeling framework. Over 20 years and overall, internal control beliefs were stable, while external control beliefs decreased. Individuals who reported higher task variety and better social integration at work at baseline also reported higher levels of control beliefs for positive life outcomes. In addition, higher social integration at work at baseline was related to lower levels of external control beliefs. Work characteristics at baseline were not associated with individual differences in change in control beliefs across the 20-year observational interval. In summary, our findings suggest that work experiences at the prime of job-related development around the midst of the fifth decade of life do not play a major role in subsequent control beliefs development across 20 years. However, investigations measuring control beliefs as well as work characteristics continuously over a long period of time are necessary to shed light on reciprocal influences between work and personality.

RESUMEN

OBJECTIVES: Work is an important developmental context in adulthood, yet little is known about how it contributes to personality trajectories in midlife. The present study examines how subjectively perceived work environment (autonomy, innovation, social integration, stress) and objectively measured work activities (activities related to information and people, physical/manual activities) are related to levels of Big Five personality traits at age 44 and to change over 20 years. METHODS: We analyzed four-wave longitudinal data from N = 374 participants (born 1950-1952; Mage T1 = 44 years, SD = 1; 44% women) from the Interdisciplinary Longitudinal Study of Adult Development and Aging (ILSE) within the structural equation modeling framework. RESULTS: At baseline, subjective perceptions of work environments showed a higher number of significant associations with personality than objective work activities. Over time, small declines in neuroticism and extraversion and small increases in agreeableness and conscientiousness were observed, which were largely independent of work characteristics. CONCLUSIONS: Our findings show slight changes in most Big Five traits from age 44 to 64, which were mostly unrelated to work characteristics. More research is needed to uncover the sources and dynamics of personality trait change in midlife and the role of work for personality trajectories.

RESUMEN

OBJECTIVE: Many studies investigating age-related mean differences in life satisfaction disregard potential differences in the structure of the life satisfaction construct. Because developmental tasks at different life stages vary and thus the salience of specific life domains (e.g., health, finances, relationships, etc.) might differ, life satisfaction might differ between age groups in its underlying structure and meaning. METHOD: To address this issue, we investigated the covariance structure of life satisfaction as measured by the Satisfaction with Life Scale (SWLS) and the domains of health satisfaction and financial satisfaction with local structural equation modeling. We analyzed data from 8341 U.S. citizens between the ages of 30 and 97 who participated in the Panel Study of Income Dynamics. Furthermore, we explored the association of respondents' health and financial status with life satisfaction. RESULTS: Both the SWLS and domain items were found to be invariant across age. The health and financial status accounted for small proportions of variance in overall life satisfaction and the respective domain satisfactions significantly at all ages. CONCLUSION: The current analysis indicates that across the adult age range, general life satisfaction is qualitatively the same, and health and financial satisfaction are equally integrated into overall life satisfaction.

RESUMEN

Enduring patterns of socially aversive behavior are ascribed to stable personality disorders (such as narcissistic or antisocial tendencies) in clinical psychology or to so called "dark" traits in personality psychology. As recently shown, the substantial overlap among the latter constructs is attributable to a single underlying disposition, called the Dark Factor of Personality (D). Whereas evidence supports the conceptualization of D as the core of aversive traits, the structure of the specific factors of D received less empirical attention so far. To this end, this study further scrutinizes the internal structure of D with items stemming from 12 different aversive traits assessed in three large and heterogeneous samples (total N > 160,000). Specifically, we (a) explored the bifactor structure of D using a modified "bass-ackwards" approach, (b) cross-validated the identified factor solutions via confirmatory factor analyses, and (c) examined the empirical relation of D and the specific factors to five criterion measures. Results indicate that a bifactor structure modeling D along with five specific factors-or themes-labeled Callousness, Deceitfulness, Narcissistic Entitlement, Sadism, and Vindictiveness, best describes the internal structure of D.

RESUMEN

Comparisons of results from studies of executive function (EF) in early childhood to those of EF in middle and late childhood suggest that individual differences in EFs may differentiate from a unitary factor in early childhood to an increasingly multidimensional structure in middle childhood and adolescence. We tested whether associations among EFs strengthened from middle childhood to adolescence using cross-sectional data from a population-based sample of 1019 children aged 7-15 years (M = 10.79 years). Participants completed a comprehensive EF battery consisting of 15 measures tapping working memory, updating, switching, and inhibition domains. Moderated factor analysis, local structural equation modeling, and network modeling were applied to assess age-related differences in the factor structure of EF. Results from all three approaches indicated that working memory and updating maintained uniformly high patterns of covariation across the age range, whereas inhibition became increasingly differentiated from the other three domains beginning around 10 years of age. However, consistent with past research, inhibition tasks were only weakly intercorrelated. Age-related differences in the organization of switching abilities were mixed.
