Abstract
Given the prevalence of depression in society today, it is essential to identify individual differences in personality that may protect against or confer risk for depressive features. Certain psychopathic traits, such as social charm and fearlessness, may place individuals at decreased risk for depression, whereas others, such as antisociality and recklessness, may place individuals at increased risk. In the present study, I sought to elucidate the associations among the dimensions of psychopathy and depression in two large, mixed-gender North American community samples (n1=430; n2=441) recruited via Amazon's Mechanical Turk (MTurk). I used multiple indices of both psychopathy and depression, including two widely used self-report measures of depression and three self-report psychopathy measures. Consistent with previous research, Boldness features were moderately negatively correlated with depression, whereas Disinhibition features were moderately positively correlated with depression (e.g., Benning et al., 2005). Coldheartedness was negatively associated with depression, although the magnitude of this relation was weak, whereas Meanness was positively related to depression. There were virtually no gender differences in the relations between psychopathy and depression. Moreover, there was little evidence that Boldness features protected against depression in the presence of the disinhibited and mean features of psychopathy. In addition, psychopathy broadly incremented general personality traits, specifically Extraversion and Neuroticism, in predicting depression, although the incremental contribution was relatively small in magnitude. Finally, psychopathy's differential associations with depression were largely mirrored in the relations among dimensions of psychopathy and other internalizing features, namely anger and anxiety. These findings demonstrate that individual differences in personality are significant predictors of depressive symptoms.
