Beyond "post," "traumatic," "growth," and prediction in research on posttraumatic growth.

Thirty years after the introduction of posttraumatic growth (PTG), research on the concept has expanded dramatically. Novel theoretical perspectives included in this special issue, however, demonstrate that nearly every element of PTG requires revision. "Post" implies a definitive before and after adversity that simply does not exist, either empirically or in the everyday navigation of adversity, especially for marginalized people.

Beyond the factor indeterminacy problem using genome-wide association data.

Latent factors, such as general intelligence, depression and risk tolerance, are invoked in nearly all social science research where a construct is measured via aggregation of symptoms, question responses or other measurements. Because latent factors cannot be directly observed, they are inferred by fitting a specific model to empirical patterns of correlations among measured variables. A long-standing critique of latent factor theories is that the correlations used to infer latent factors can be produced by alternative data-generating mechanisms that do not include latent factors.

Subjective experiences of life events match individual differences in personality development.

The last 2 decades have witnessed increased research on the role of life events in personality trait development, but few findings appear to be robust. We propose that a key to resolving this issue is incorporating individuals' subjective experiences into the study of event-related development. To test this, we developed and administered a survey about event-related personality change to a representative Dutch sample (N = 5,513, Ages 16-95) and linked their responses to 12-year trajectories of measured Big Five development.

Psychological change before and after religious conversion and deconversion.

Objective: Theory and anecdotal evidence suggest that people undergo psychological changes before and after religious conversion and deconversion. Yet, existing research provided inconclusive evidence. Here, we examined psychological change before, during, and after institutional conversion and deconversion in a large-scale longitudinal study.

Transactional effects between personality and religiosity.

Do changes in religiosity beget changes in personality, or do changes in personality precede changes in religiosity? Existing evidence supports longitudinal associations between personality and religiosity at the between-person level, such that individual differences in personality predict subsequent individual differences in change in religiosity. However, no research to date has examined whether within-person changes in personality lead to subsequent changes in religiosity. Using random intercept cross-lagged panel models (RI-CLPM), we investigated between- and within-person associations between the Big Five personality traits and three aspects of religiosity-belief in God, service attendance, and prayer-in a sample of over 12,000 Dutch individuals across 11 annual assessments.

Personality stability and change: A meta-analysis of longitudinal studies.

Past research syntheses provided evidence that personality traits are both stable and changeable throughout the life span. However, early meta-analytic estimates were constrained by a relatively small universe of longitudinal studies, many of which tracked personality traits in small samples over moderate time periods using measures that were only loosely related to contemporary trait models such as the Big Five. Since then, hundreds of new studies have emerged allowing for more precise estimates of personality trait stability and change across the life span.

Refining the maturity principle of personality development by examining facets, close others, and comaturation.

Across adulthood, people tend to experience psychologically adaptive personality trait change, a robust finding known as the maturity principle of personality development. We identify three open areas of inquiry regarding personality maturation and address them in a preregistered study, using a sample of U.S.

The impact of childhood lead exposure on adult personality: Evidence from the United States, Europe, and a large-scale natural experiment.

Childhood lead exposure has devastating lifelong consequences, as even low-level exposure stunts intelligence and leads to delinquent behavior. However, these consequences may be more extensive than previously thought because childhood lead exposure may adversely affect normal-range personality traits. Personality influences nearly every aspect of human functioning, from well-being to career earnings to longevity, so effects of lead exposure on personality would have far-reaching societal consequences.

Personality Predictors of Emergency Department Post-Discharge Outcomes.

Personality traits are important predictors of health behaviors, healthcare utilization, and health outcomes. However, we know little about the role of personality traits for emergency department outcomes. The present study used data from 200 patients (effective Ns range from 84 to 191), who were being discharged from the emergency department at an urban hospital, to investigate whether the Big Five personality traits were associated with post-discharge outcomes (i.

The Relationship Between Career Success and Sense of Purpose: Examining Linkages and Changes.

Objectives: Although researchers have linked sense of purpose to working status, there are few studies examining how specific characteristics of work may correlate with sense of purpose. The aim of the current study is to extend prior research by assessing the degree to which objective and subjective forms of career success-occupational prestige and work satisfaction-are associated with levels of and changes in sense of purpose.

Methods: Participants were part of the Rochester Adult Longitudinal Study (N = 307), which contains multiple cohorts of participants each assessed at multiple waves (full age range: 42-71).

Changes in optimism and pessimism in response to life events: Evidence from three large panel studies.

Although individuals vary in how optimistic they are about the future, one assumption that researchers make is that optimism is sensitive to changes in life events and circumstances. We examined how optimism and pessimism changed across the lifespan and in response to life events in three large panel studies (combined = 74,886). In the American and Dutch samples, we found that optimism increased across younger adulthood, plateaued in midlife, and then decreased in older adulthood.

A facet atlas: Visualizing networks that describe the blends, cores, and peripheries of personality structure.

We created a facet atlas that maps the interrelations between facet scales from 13 hierarchical personality inventories to provide a practically useful, transtheoretical description of lower-level personality traits. We generated this atlas by estimating a series of network models that visualize the correlations among 268 facet scales administered to the Eugene-Springfield Community Sample (Ns = 571-948). As expected, most facets contained a blend of content from multiple Big Five domains and were part of multiple Big Five networks.

Log on and Prosper? Little Evidence for Codevelopment Between Psychological Adjustment and Technology Use in Older Adulthood.

Objectives: Researchers have hypothesized that using Information and Communications Technology (ICT), such as e-mail and social media, may buffer older adults from normative age-graded declines in psychological adjustment. However, past intervention research has been unable to conclusively evaluate this proposition, and no studies to date have examined this topic using naturalistic large-scale longitudinal methods.

Method: In this preregistered study, we examined the codevelopment between three aspects of psychological adjustment (loneliness, satisfaction with life [SWL], and depressiveness) and three factor-analytically derived clusters of ICT use (instrumental, social, and media) using a longitudinal representative sample of 2,922 Dutch adults aged 65 and older that contributed data annually from 2012 to 2017.

Health, environmental, and animal rights motives for vegetarian eating.

Health, the environment, and animal rights represent the three main reasons people cite for vegetarian diet in Western societies. However, it has not been shown that these motives can be distinguished empirically, and little is known about what kind of people are likely to be compelled by these different motives. This study had three goals.

Charting self-esteem during marital dissolution.

Objective: The purpose of this study was to chart changes in self-esteem before and after marital dissolution to identify the factors that shape individuals' self-esteem during this life transition.

Method: We analyzed 10 annual waves of self-esteem data from 291 divorcees from a nationally representative panel study of the Netherlands (N ~ 13,000). We charted the course of self-esteem before and after marital dissolution and tested a broad set of moderator variables that may shape individuals' self-esteem trajectories.

Does Openness to Experience matter in love and work? Domain, facet, and developmental evidence from a 24-year longitudinal study.

Objective: Although numerous studies have demonstrated that personality traits predict important love and work outcomes, there is mixed evidence for the relevance of Openness to Experience to love and work. We sought to better understand the long-term consequences of Openness in these two domains.

Method: We examined the associations between Openness and 51 love and work outcomes using data from a 24-year longitudinal study of UC Berkeley students (N = 497) followed from the beginning of college into midlife.

Retirement is associated with change in self-esteem.

We examined the course of self-esteem during the transition to retirement in a sample of 690 retirees (ages 51-81) and a propensity-score matched-comparison group of 515 nonretirees drawn from a nationally representative longitudinal study in the Netherlands. The average retiree decreased in self-esteem in the 5 years before retirement and remained stable in self-esteem in the 5 years following retirement. We also found significant individual differences in retirees' self-esteem trajectories but failed to identify moderators that may account for these individual differences.

Personality trait development across the transition to retirement.

In this study, we examined trajectories of Big Five personality development in the 5 years before and after retirement. Our sample was composed of 690 retirees (ages 51-81) and a propensity-score matched comparison group of 532 nonretirees drawn from a nationally representative longitudinal study of the Netherlands. Participants contributed data across a maximum of 6 measurement waves over a period of 7 years.

Openness to experience and culture-openness transactions across the lifespan.

We examined the life span development of openness to experience and tested whether change in this personality trait was associated with change in cultural activity, such as attending the opera or visiting museums. Data came from the Dutch Longitudinal Internet Study for the Social Sciences panel, which includes 5 personality assessments across a 7-year period of a nationally representative sample of 7,353 individuals, aged 16 to 95 years. Latent growth curve analyses indicated that on average, openness remained relatively stable in emerging adulthood before declining in midlife and old age.

Individual differences in personality change across the adult life span.

Objective: A precise and comprehensive description of personality continuity and change across the life span is the bedrock upon which theories of personality development are built. Little research has quantified the degree to which individuals deviate from mean-level developmental trends. In this study, we addressed this gap by examining individual differences in personality trait change across the life span.
