Gender differences in depression: the role of personality factors.
The goal of the study was to determine the association between gender and the Big Five personality factors, and to identify the role of personality factors in the association between gender and depression among adults in the United States. Data were drawn from the Midlife Development in the United States Survey (N=3032). Multivariate analysis of variance (MANOVA) was used to examine gender differences on the Big Five personality factors (i.e. agreeableness, neuroticism, openness to experience, extraversion, and conscientiousness). Multivariate logistic regression analyses were conducted to examine the relation between gender and depression, and to test whether this association is moderated by neuroticism. Levels of neuroticism, agreeableness, extraversion, and conscientiousness were significantly higher among females than among males; in contrast, level of openness to experience was significantly higher among males. Female gender was associated with increased odds of experiencing depression. Results showed that neuroticism played a significant contributory role in the relationship between being female and major depression, though the role of gender remained statistically significant after adjustment. These data suggest that gender differences in personality factors, specifically neuroticism, may play a key role in the well-documented gender difference in depression. Our findings indicate that neuroticism may moderate the association between female gender and increased risk of depression among adults. These findings require replication using longitudinal data.
