Scoring and interpretation
Possible scores range from 0 to 80. Higher scores are associated with higher social anxiety. The author of the measure, Peters (2000), defined the cut-off score as 36. In other words, a score of 36 or higher suggests a possible diagnosis for social anxiety.
Reliability and validity
The SIAS has shown validity when compared with other measures such as the Social Phobia and Anxiety Inventory (SPAI) as well as clinician-rated scores.
