Objectives: The current study was aimed to investigate rumination and avoidance in healthy individuals and those with depressive and social anxiety disorders. Method: Sixty patients (30 with depressive disorder, and 30 with social anxiety disorder), and 120 nonclinical participants answered research questionnaires including Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II), General Health Questionnaire (GHQ), Response Styles Questionnaire (RSQ), Cognitive Behavioral Avoidance Scale (CBAS) and Post Event Processing Questionnaire (PEPQ). Discriminant function analysis revealed major differences among the groups. Results: The findings indicated significant difference between individuals with depression and those with social anxiety disorder in three variables including cognitive nonsocial avoidance (p<0.001), behavioral nonsocial avoidance (p<0.001) and rumination (p<0.001). No significant differences were found between two clinical groups in three variables of post event processing, social avoidance and distraction. Cognitive nonsocial avoidance and rumination variables were the best predictors for distinguishing social anxiety group from depressed group. Conclusion: The current study showed some overlap in cognitive psychopathology of depressive and social anxiety disorders. It seems that rumination, post event processing, and avoidance are on a continuum from normal to abnormal. However, rumination and cognitive nonsocial avoidance were distinctive features of depression. This study provided evidences supporting both dimensional and categorical approaches.
