The validity of the social avoidance and distress scale and the fear of negative evaluation scale with social phobic patients

Turner, McCanna and Beidel's (1987) recent evaluation of the Social Avoidance and Distress Scale (SADS) and the Fear of Negative Evaluation Scale (FNE) with anxiety disordered patients concluded that the SADS and FNE lacked discriminant validity and may be inappropriate for subject selection or outcome evaluation in studies of social phobia. This paper raises some concerns with the interpretation of the data presented by Turneret at. (1987) and presents additional data from studies in our laboratories that may qualify their conclusions. It is asserted that (a) the SADS and FNE are not appropriate for diagnostic screening of social phobic patients, (b) Turner et al.'s findings may have been the result of clinically meaningful social anxiety in several of the anxiety disorders, (c) significant differences among the anxiety disorders may have been hidden by heterogeneity among patients who receive the diagnosis of social phobia, and (d) the distribution of FNE scores in Turner et al.'s sample may have been unusually depressed.
