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.
