Relations of the factors of the tripartite model of anxiety and depression to types of social anxiety.
Our primary goal was to examine the relations of the specific components of the tripartite model of anxiety and depression [Clark, L. A., Watson, D. (1991). Tripartite model of anxiety and depression: Psychometric evidence and taxonomic implications. Journal of Abnormal Psychology, 100, 316-336] to two types of social anxiety (social interaction anxiety and performance anxiety) in 148 individuals with social phobia. In line with previous research, overall social anxiety was more closely related to the anhedonic depression (AD) or low positive affect factor of the tripartite model than to the physiological hyerarousal factor, controlling for general distress. However, as hypothesized, performance anxiety was more closely associated with the physiological hyerarousal factor, whereas social interaction anxiety was more closely associated with the AD or low positive affect factor. We also examined the convergent and discriminant validity of the Mood and Anxiety Symptom Questionnaire (MASQ; [Watson, D., Clark, L. A. (1991). The mood and anxiety symptom questionnaire. Unpublished manuscript, University of Iowa City]). Intercorrelations of the MASQ subscales were as expected, but correlations with measures of social anxiety, nonsocial anxiety, and depression provided only modest support for convergent and discriminant validity. Findings from this study provide a more detailed account of the specific components of the tripartite model that characterize the diversity of symptoms subsumed by social phobia.
