ObjectiveWe evaluated the role of natural disaster adversity on personality development in the wake of a hurricane, and the moderating role of previous hurricane exposure.MethodWe used a two‐wave longitudinal design and a diverse sample of emerging adults (n = 691; mean age = 22 years; 72% females, 27% European American, 29% Latino, 23% Asian American, 15% African American, 6% Multiracial/Other) who were exposed to one of the most damaging hurricanes on record, though to differing degrees. Immediately after the hurricane, we assessed objective individual‐level hurricane exposure, previous exposure to hurricanes, demographics, socioeconomic status, and Big Five personality traits. One year later, we re‐assessed Big Five personality traits.ResultsUsing latent change models, we found significant individual differences both in participants’ initial levels of personality traits at baseline, as well as in their developmental patterns of change in the year following the hurricane. However, there was no evidence of mean‐level change. Moreover, neither hurricane exposure level, nor its interaction with previous exposure showed statistically significant associations with the rates of change in any personality trait.ConclusionsThe present findings support a stability account, whereby individuals largely maintain their personality dispositions following an adverse life event, in this case a hurricane.

Does deviancy or adjustment predict creativity? To address this question, we tested the association between personality profile normativeness (similarity between one's personality profile and the average profile-a proxy for the deviancy-adjustment continuum) and creativity across four different samples (total N = 348 768). We used a wide range of creativity measures, including self-reported, informant-reported, behavioural, and occupational creativity, as well as several essential statistical controls (i.e., demographics, socio-economic background, intelligence, and life satisfaction). Furthermore, we employed both cross-sectional and longitudinal designs, including samples of college students and representative adult populations. We found that people who had more normative personality profiles were more creative. However, this association only held within modality (i.e. when both personality and creativity were either self-reported or informant-reported). We did not find robust associations between personality profile normativeness and laboratory-based behavioural measures of creativity, occupational creativity, or creative achievements. We discuss alternative explanations for the observed adjustment-creativity link, specifically, implicit theories of creativity and person perception biases (halo effects). Notably, the findings did not support the idea that deviancy breeds creativity, suggesting that the famed 'mad genius' hypothesis might not hold among the general population.

This study assessed the co-development of adversity and effortful control based on a sample of Mexican-origin youth ( N = 674) and their parents. We used a four-wave longitudinal design and followed target participants from age 10 to 16. At each time point, we measured adversity experienced by the children and their parents and children’s effortful control (self- and parent-reported). We also assessed children’s shift-and-persist coping strategies at ages 14 and 16. Across time, we found slight decreases in child-adversity and slight increases in parent-adversity. Based on bivariate LGC analyses, we found that the strongest effects surfaced for child- (vs. parent-) adversity. Specifically, we found that greater increases in child-adversity were associated with greater decreases in effortful control from ages 10 to 16. Moreover, we found a positive association between initial levels of child-adversity and the slope of effortful control, as well as a cross-sectional negative association between child- and parent-adversity and effortful control (at age 10). We found no evidence of moderation by shift-and-persist coping strategies. In sum, our results suggest that, on average, Mexican-origin youth exposed to more adversity might experience more maladaptive change with respect to effortful control.

We examined the role of self-efficacy in preventing bystander inaction in dangerous alcohol situations. Participants (N = 504) completed an online survey that assessed whether they had previously witnessed or intervened in alcohol-related emergencies, their self-efficacy for intervening, and their likelihood of intervening in the future. Previously intervening was positively associated with self-efficacy and likelihood of intervening in the future. Furthermore, self-efficacy mediated the association between previously intervening and likelihood of intervening in the future. In conclusion, self-efficacy for intervening in social situations is associated with intervening in alcohol-related emergencies and is an important factor to consider when designing bystander interventions.
