Abstract
Personality changes throughout the life course and change is often caused by environmental influences, such as critical life events. In the present study, we investigate personality trait development in emerging adulthood as a result of experiencing two major life events: graduating from school and moving away from home. Thereby, we examined the occurrence of the two life events per se and the subjective perception of the critical life event in terms of valence. In addition, we postulate a moderation effect of the construct of mindset, which emphasizes that beliefs over the malleability of global attributes can be seen as predictors of resilience to challenges. This suggests that mindset acts as a buffer for these two distinct events. In a large longitudinal sample of 1,243 people entering adulthood, we applied latent structural equation modeling to assess mean-level changes in the Big Five, the influence of life events per se, the subjective perception of life events, and a moderating role of mindset. In line with maturity processes, results showed significant mean-level changes in all Big Five traits. While no changes in the Big Five dimensions were noted when the mere occurrence of an event is assessed, results indicated a greater increase in extraversion and diminished increase in emotional stability when we accounted for the individual's (positive/negative) perception of the critical life event. In case of extraversion, this also holds true for the moderator mindset. Our findings contribute valuable insights into the relevance of subjective appraisals to life events and the importance of underlying processes to these events.
Highlights
This study aims to contribute to the literature around external and internal influences on personality development in emerging adulthood by analyzing changes in the Big Five, the influences of the occurrence of life events per se vs. their subjective perception, and the possible moderating effects of mindset in a longitudinal study with a large sample
Most prior studies have focused on personality development in adulthood (e.g., Roberts and Jackson, 2008; Lucas and Donnellan, 2011; Wrzus and Roberts, 2017; Damian et al, 2018; Denissen et al, 2018), but emerging adulthood is marked by tremendous changes; we focus our analyses on this period
We investigated how two critical life events influence personality trait change, the role of subjective perceptions of these events, and how internal belief systems like mindset moderate the impact of life events on trait change
Summary
Individuals experience physical and psychological changes across the entire lifespan. The exact course of internal and external changes depends on various criteria. Researchers have expended considerable effort in studying how personality develops across the lifespan; this has, in turn, incited a controversy about the stability and variability of specific personality traits. Personality traits are considered to be relatively stable individual differences in affect, behavior, and/or cognition (Johnson, 1997). The Big Five traits of conscientiousness and agreeableness appear to be rather stable and continuously
