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. METHOD: We used 11-wave longitudinal data from a nationally representative sample of Dutch adults (N ~ 20,000) to assess changes in religious beliefs and practices, personality traits, and well-being before, during, and after conversion to and deconversion from Christianity. RESULTS: Converts (N = 181) increased in service attendance and prayer, but not in their belief in God, as they approached conversion. Deconverts (N = 450) declined in religious beliefs and practices before, during, and after deconversion. In terms of personality, converts displayed small, unexpected declines in emotional stability, extraversion, and agreeableness at time of conversion. Deconverts declined in agreeableness, conscientiousness, and openness at time of deconversion. Neither group showed changes in their well-being. CONCLUSION: The present findings suggest that psychological changes during religious conversion and deconversion are generally small and mostly manifest as changes in people's religious beliefs and practices. Findings are discussed in the context of person-religion fit, meaning-making, and sociocultural motive perspectives on religious change.

Nature and Impact of Reference Group Effects in Personality Assessment Data.

People have a tendency to engage in social comparisons when evaluating and reporting on personality. This tendency and variation in who people compare their personality to is known as the reference group effect and has been largely discussed in cross-cultural research. However, reference group effects have implications beyond cross-cultural research and should be considered when collecting and interpreting personality data. In the present study, we examined the nature and impact of reference group comparisons on the Big Five personality traits in a sample of N = 1194 participants. Specifically, we examined what reference groups participants most believed they compared their personality to, and which reference group was actually the most impactful on trait scores. We found that most people believed they compared their personality to people in general. However, the most influential reference group was people the same age as the participants. Moreover, we found that people mostly engaged in between- as opposed to within-person comparisons when evaluating their own personality. Overall, our findings highlight that people have relatively little insight into the comparisons they engage in when make judgments on personality. Discussion focuses on theoretical and practical implications of our findings in light of personality assessment data.

Personality aspects and proenvironmental attitudes.

OBJECTIVE: Climate change is a serious threat. Personality psychologists can help address this threat by understanding what kind of people tend to endorse proenvironmental attitudes and engage in sustainable behavior. Previous research supports reliable associations between proenvironmental attitudes and personality traits. However, this research has generally aggregated different kinds of attitudes into a single composite and has focused on the domain level of personality traits. METHOD: This study explored how 10 lower-order aspects of the Big Five personality traits were related to eight different proenvironmental attitudes in three convenience samples from the United States (N = 1234; 1000) and the United Kingdom (N = 538). RESULTS: All five trait domains were related to at least one proenvironmental attitude across all three samples. Seven of eight proenvironmental attitudes could be predicted by one or more traits in all three samples. We also found evidence that the Openness aspect of Openness to Experience was a more consistent predictor of proenvironmental attitudes than the Intellect aspect. In contrast, there was little benefit in distinguishing between the aspects of other trait domains. We did not find evidence that age or political orientation moderated the associations between proenvironmental attitudes and personality. CONCLUSION: Results point to the need for more fine-grained research on individual differences in proenvironmental attitudes and behavior.

Effects of Reference Group Instructions on Big Five Trait Scores.

People responding to personality questionnaires rate themselves by comparing themselves to some reference group, but this reference group is typically not specified. In this study, we examined the differences between Big Five trait scores when people responded to trait questionnaires without a specified reference group, as is typical in personality assessment, and when they were asked to compare themselves to people in general, close others, people their age, people their same gender, their ideal self, or their past self. We found that personality scores tended to be more adaptive for between-person comparisons than for within-person comparisons. We also found that unprompted instructions produced mildly higher scores across all traits. There were few differences among between-person reference group conditions. Men rated themselves as slightly more agreeable when comparing themselves to other men. Implications for basic and applied personality assessment are discussed.

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. We found between-person associations between all Big Five traits and religiosity, yet within-person associations only between agreeableness as well as extraversion and belief in God. Specifically, individuals who increased in agreeableness or extraversion reported subsequent increases in their belief in God and, in addition, individuals who increased in their belief in God showed subsequent increases in agreeableness. We further identified significant moderating effects of gender, religious upbringing, and religious affiliation. Overall, the present findings suggest that the associations between personality traits and religiosity primarily occur at the between-person level. However, the evidence for intraindividual associations between agreeableness, extraversion, and religious belief highlights the importance of distinguishing between-person from within-person effects to broaden the understanding of the temporal dynamics between variables.
