Abstract
Recently, the number of patients with mood disorder is increasing. Although strong evidence suggests that depression is a common experience among individuals meeting criteria for borderline personality disorder, etiological findings have not been confirmed. This exploratory study is aiming to clarify relation between depression, avoidance, and borderline personality traits using covariance structure analysis with college students. As a result, depression predicts borderline personality traits mediated by avoidance and directly predicts them. However, borderline personality traits also predict depression (reversed pass model) not mediated by avoidance and fit indices for this model indicate acceptable level. In the future, further studies will be needed to reexamine this etiological model with clinical subjects.
