Methods：There are two samples in this study, one is undergraduates and the other is clinical outpatients with depressive symptoms. First, we used two samples to examine the psychometric properties of the Chinese version of the Thought Suppression Inventory and the Chinese version of the Ruminative Responses Scale. Second, we used the clinical outpatients to testing the hypothesized models of this study. We collected 110 undergraduate students, they completed demographic information questionnaire, the Chinese version of the Thought Suppression Inventory and the Chinese version of the Ruminative Responses Scale. Also, we collected 84 psychiatric outpatients, they assessed by a series of questionnaires and tests, including demographic information questionnaire, the Chinese version of the Thought Suppression Inventory and the Chinese version of the Ruminative Responses Scale, the Chinese version of the Beck Depression Inventory Second Edition, and WMS-III Letter-Number Sequencing subtest and Digit Span subtest. Finally, 67 out of 84 patients with the BDI score greater than 10 points patients were used to examine the hypothesized models of this study. Results：In psychometric properties of the Chinese version of the Thought Suppression Inventory Scale, this study found that, in both the undergraduate students and the outpatient with depressive symptoms, the intrusive factor is stable, however, the suppression attempts and the successful suppression factors are unstable. In addition, in both the undergraduates and the outpatient with depressive symptoms, the Chinese version of the Ruminative Responses Scale has good reliability and stable factor construct. In hypothesis model testing, it is based on the factor structure of the Chinese version of the Thought Suppression Inventory Scale from outpatients with depressive symptoms. We tested two models：the hypothesis model of intrusion and the hypothesis model of successful suppression. In the hypothesis model of intrusion, we found non-significant direct effects between intrusion and rumination, as well as working memory and depressive symptoms. The other direct effects between variables are significant. In addition, intrusion and rumination play the roles of mediation in this model. In the hypothesis model of successful suppression, we found significant relationships between working memory and rumination, rumination and depressive symptoms, as well as successful suppression and depressive symptoms. Conclusion：This study was the first to use clinical outpatient with depressive symptoms to examine the psychometric properties of the Chinese version of the Thought Suppression Inventory. In addition, this study incorporates the concepts of working memory, thought suppression, rumination and depressive symptoms into an integrative model, and revealed some significant findings in clinical outpatients with depressive symptoms and used this findings to explain the psychological mechanism of depression. The results of this study could provide a practical contribution for the future treatment of depression. Finally, the limitations and suggestions of this study are discussed in texts. Key words: working memory, thought suppression, rumination, depressive symptoms
