This study was carried out to examine the relationship between marital dissatisfaction and depressive symptoms using a cognitive-interpersonal approach(CIA). According to the CIA, the dysfunctional cognition and the maladaptive patterns of interpersonal relationship are originated from the earlier problems of insecure attachment. To test the validity of the CIA, the relationship among attachment level, dysfunctional attitude, and the marital communication pattern of married females were examined. Also, the relative statistical contributions for these variables were assessed. This study analyzed the correlations among variables(e.g., attachment quality, dysfunctional attitude, marital communication pattern, and depression) that are assumed to be related to marital satisfaction. In addition, the relative explanatory power of these variables for accounting marital satisfaction was estimated using a hierarchical multiple regression technique. Statistical analyses showed that the size of the predictive power of attachment quality was larger than that of the dysfunctional attitude and the marital communication. The results support the CIA, suggesting that the attachment quality is more crucial variable than the dysfunctional cognition and the interpersonal pattern for explaining marital satisfaction and depression.
