ارزیابی روایی ابعاد الگوی سه بخشی اضطراب و افسردگی

 AbstractObjectives:  The purpose of the present study was to assess the validity of Clark and Watson’s tripartite theory of anxiety and depression and to assess the differences between the two genders with regard to social anxiety, general anxiety, and depression in a sample of adolescents.  Method: In a descriptive cross-sectional study, 403 secondary students (225 girls, 178 boys) who were selected using randomized cluster sampl- ing, completed the Social Anxiety Scale for Adolescents, the Revised Children's Manifest Anxiety Scale, and the Children Depression In-ventory. The convergent and divergent validity of the tripartite model of anxiety and depression was first assessed via correlation matrix. Next, t-test was used to compare depressive and anxiety disorder between the two groups. Results: The results of the convergent and divergent validity supported Clark and Watson's tripartite theory of anxiety and depression. In comparison with males, females reported higher levels of social anxiety (p<0.01), general anxiety (p<0.01) and depression (p<0.001). Conclusion: Clark and Watson's tripartite theory of anxiety and dep-ression is confirmed despite the limitations of the model.
