Personality traits in the first degree relatives of outpatients with depressive disorders.

This study examined several hypotheses regarding the relationship between personality and depression using a family study. Relatives of outpatients with depressive disorders and controls completed a battery of personality inventories assessing sociotropy, autonomy, dependency, self-criticism, neuroticism, extraversion, and hopelessness. Relatives with current mood disorders differed from healthy relatives on almost all measures. Relatives with past histories of affective disorder were more neurotic, self-critical and dependent than healthy relatives. Results suggest that scores on personality measures are mood state-dependent, and may change as a function of mood disorder.
