The scale is composed of 24 items divided into 2 subscales, 13 concerning performance anxiety, and 11 pertaining to social situations. The 24 items are first rated on a Likert Scale from 0 to 3 on fear felt during the situations, and then the same items are rated regarding avoidance of the situation. Combining the total scores for the Fear and Avoidance sections provides an overall score with a maximum of 144 points. The clinician administered version of the test has four more subscale scores, which the self-administered test does not have. These additional four subscales are: fear of social interaction, fear of performance, avoidance of social interaction and avoidance of performance. Usually, the sum of the total fear and total avoidance scores are used in determining the final score (thus, essentially it uses the same numbers as the self-administered test). Research supports a cut-off point of 30, in which SAD is unlikely. The next cut-off point is at 60, at which SAD is probable. Scores in this range are typical of persons entering treatment for the non-generalized type of SAD. Scores between 60 and 90 indicate that SAD is very probable. Scores in this range are typical of persons entering treatment for the generalized type of SAD. Scores higher than 90 indicate that SAD is highly probable. Scores in this range often are accompanied by great distress and difficulty in social functioning, and are also commonly seen in persons entering treatment for the generalized type of SAD.
