Objective: Examining the personality and well‐being correlates of positive event diversity. Background: Past research has highlighted that personality traits are linked to the frequency of daily positive events. This study is the first to examine positive event diversity, the extent to which positive events are spread across multiple types of positive life domains, as well as its personality and well‐being correlates. Method: We conducted parallel analyses of three daily diary datasets (Ns = 1919, 744, and 1392) that included evening assessment of daily positive events and affective well‐being. The Big Five personality traits were assessed in baseline surveys. Results: Positive Event Diversity was related to higher person‐mean daily positive affect but not negative affect. Higher Extraversion, Agreeableness, Openness, and lower Neuroticism were correlated with more positive event diversity. These associations became nonsignificant when controlling for positive event frequency. Positive event frequency moderated the link between positive event diversity and person‐mean affect, such that higher positive event diversity was associated with higher negative and lower positive affect for people who experienced more frequent positive events. Conclusions: No consistent evidence was found for personality as a moderator of the positive event diversity–well‐being link across the three studies. Further, the well‐being implications of positive event diversity may be better understood when interpreting them alongside indexes of positive event frequency. [ABSTRACT FROM AUTHOR]

Objective: This study aims to explore the reciprocal associations between personality traits (conscientiousness and openness to experience) and academic achievement in adolescents, using the Personality Achievement Saturation Hypothesis (PASH). Background: Personality traits, especially conscientiousness, and openness, have been identified as strong predictors of academic achievement. The PASH provides a framework for understanding these relationships but has mainly been studied from a unidirectional perspective. This study extends the PASH to examine reciprocal associations and how they vary with different achievement indicators. Methods: Using large‐scale panel data (N = 6482) of secondary school students in Germany, we applied cross‐lagged panel models and latent change score models to examine the differential reciprocal associations between personality traits (conscientiousness/openness) and academic achievement (school grades/achievement test scores) in language and math over two years from grades 7 to 9. Results: In line with the PASH, initial levels of conscientiousness were more strongly associated with school grades than with achievement test scores over two years. Simultaneously, prior school grades were more strongly associated with conscientiousness over two years. However, initial levels of openness did not show differential associations with either school grades or achievement test scores over two years. Similarly, prior school grades and achievement test scores were also not differentially associated with openness over two years. Conclusions: Our findings introduce an innovative lens through which we observe how the PASH can be leveraged to explain the differential reciprocal associations between conscientiousness and academic achievement. Further research is needed to examine if PASH could be similarly extended to disentangle the associations between openness and academic achievement. [ABSTRACT FROM AUTHOR]

ObjectiveIndividual differences in adolescent personality are related to a variety of long-term health outcomes. While previous studies have demonstrated sex differences and non-linear changes in personality development, these results remain equivocal. The current study utilized longitudinal data (n = 831) from the National Consortium on Alcohol and Neurodevelopment in Adolescence to examine sex differences in the development of personality and the association between substance use and personality.MethodParticipants (ages 12-21 at baseline) completed the Ten-Item Personality Inventory and self-reported past year alcohol and marijuana use at up to 7 yearly visits. Data were analyzed using generalized additive mixed-effects models and linear mixed-effects models.ResultsFindings support linear increases in agreeableness and conscientious and decreases in openness with age and inform on timing of sex-specific non-linear development of extraversion and emotional stability. Further, results provide novel information regarding the timing of the association between substance use and personality, and replicate past reporting of differential associations between alcohol and marijuana use and extraversion, and sex-dependent effects of marijuana use on emotional stability.ConclusionsThese findings highlight the importance of modeling sex differences in personality development using flexible non-linear modeling strategies, and accounting for sex- and age-specific effects of alcohol and marijuana use.

Objective: Personality change is a growing field of interest, but relatively few studies have examined causes of change in Openness. We investigated whether it is possible to influence state Openness, and through what mechanisms this effect may occur. Method: In two experiments (Study 1: N = 144, Mage = 36.4, 58% female, 88% White; Study 2: N = 269, Mage = 34.0, 60% female, 91% White), participants reflected on and wrote about a personal experience requested to be either: nostalgic; positive and novel (Study 1); positive or novel (Study 2); or ordinary. They rated the events for nostalgia, positivity, novelty, and sociality, and completed measures of state positive affect, self‐esteem, social connectedness, meaning in life, and state Openness. Results: Participants who recalled positive and/or novel events reported greater state Openness than those who recalled ordinary events. In Study 1, this also applied to those recalling nostalgic events. Event ratings of positivity (both studies), nostalgia and novelty (Study 2) independently predicted state Openness. State positive affect and self‐esteem were independent predictors in both studies, suggesting possible indirect paths. Conclusions: Reflecting on nostalgic, positive, and novel experiences can increase state Openness. This finding may be useful for interventions targeting trait‐level change. [ABSTRACT FROM AUTHOR]

Objective: We investigate how the relations between the Big Five personality traits and political preferences develop over a campaign.Method: We rely on a six-wave nationwide longitudinal survey from the 2008 U.S. election that included 20,000 respondents (Mage  = 49, SD = 15; 53% women, 47% men; 82% White, 8% Black, 6% Hispanic/Latino, 1% Asian, 1% Native American, 2% other). Survey weights were applied to approximate a representative sample of the U.S.Population: Ns for reported analyses range from 5,160 to 12,535.Results: First, Conscientiousness and Openness to Experience were significantly associated with changes in outcomes over time, such that individuals higher in Conscientiousness and lower in Openness tended to become more conservative, identify as more Republican, and evaluate John McCain more favorably relative to Barack Obama. Second, the effects of personality on candidate evaluations were mediated by partisanship and ideology. Finally, we find that the relations between traits and late-campaign candidate evaluations are stronger than those between traits and early-campaign candidate evaluations.Conclusions: Personality plays an important, dynamic role in the formation and change of political preferences over the course of political campaigns-a role not entirely visible in cross-sectional analyses.

Objective: Novelty seeking (the tendency to explore things novel and unfamiliar) has been extensively researched in the clinical and health domains, but its effects on creative performance are largely unknown. We examined whether creativity-related personality traits (openness to experience and extraversion) are associated with novelty seeking, and whether novelty seeking is linked to, and facilitates, creativity.Method: In Study 1a (N = 230; Mage  = 20; 64% females) and Study 1b (N = 421; Mage  = 19; 65% females), we measured extraversion, openness to experience, novelty seeking, and divergent thinking. To provide causal evidence for the relation between novelty seeking and creativity, in Study 2 (N = 147; Mage  = 27; 75% females), we manipulated people's motivation to seek novelty and then measured subsequent divergent thinking.Results: In Studies 1a and 1b, we demonstrated that trait novelty seeking is associated with openness and extraversion, on the one hand, and divergent thinking on the other. In Study 2, the novelty seeking manipulation led to greater divergent thinking.Conclusions: We conclude that novelty seeking is linked to openness to experience and extraversion, and that it can lead to greater divergent thinking.

Objective Although Loevinger's model of ego development is a theory of personality growth, there are few studies that have examined age-related change in ego level over developmentally significant periods of adulthood. To address this gap in the literature, we examined mean-level change and individual differences in change in ego level over 18 years of midlife. Method In this longitudinal study, participants were 79 predominantly White, college-educated women who completed the Washington University Sentence Completion Test in early (age 43) and late (age 61) midlife as well as measures of the trait of Openness (ages 21, 43, 52, and 61) and accommodative processing (assessed from narratives of difficult life events at age 52). Results As hypothesized, the sample overall showed a mean-level increase in ego level from age 43 to age 61. Additionally, a regression analysis showed that both the trait of Openness at age 21 and accommodative processing of difficult events that occurred during (as opposed to prior to) midlife were each predictive of increasing ego level from age 43 to age 61. Conclusions These findings counter prior claims that ego level remains stable during adulthood and contribute to our understanding of the underlying processes involved in personality growth in midlife.
