The role of cluster B and C personality disturbance in the course of depression: a prospective study.
The association between personality disturbance and depression has been noted consistently. Prospective tests of personality's impact on the course of depression, however, are lacking. In a sample of 159 undergraduates who experienced at least one prospective depressive episode, dimensional scores for clusters B and C personality disturbance were examined as prospective predictors of four indicators of the course of depression: severity, episode duration, symptomatic chronicity and number of episodes. Cluster C personality disturbance, characterized by anxious and fearful features, predicted depression chronicity. Cluster B, characterized by dramatic, emotional and/or erratic features, predicted severity and duration of depression. The findings are discussed in terms of the possible mechanisms underlying the effects of clusters B and C, as well as implications for future research.
