Social phobia has become a focus of increased research since its inclusion in DSM-III. However, assessment of social phobia has remained an underdeveloped area, especially self-report assessment. Clinical researchers have relied on measures that were developed on college populations, and these measures may not provide sufficient coverage of the range of situations feared by social phobic individuals. There is a need for additional instruments that consider differences in the types of situations (social interaction vs. situations involving observation by others) that may be feared by social phobics and between subgroups of social phobic patients. This study provides validational data on two instruments developed by Mattick and Clarke (1989): the Social Interaction Anxiety Scale (SIAS), a measure of anxiety in social interactional situations, and the Social Phobia Scale (SPS), a measure of anxiety in situations involving observation by others. These data support the use of the SIAS and SPS in the assessment of individuals with social phobia.
