WHAT THE TEST MEASURES

About This Assessment

Social Interaction Anxiety Scale (SIAS) Test - Symptoms and Signs

social anxiety

Social anxiety can extend beyond ordinary shyness and may interfere with effective communication and participation with others. The Social Interaction Anxiety Scale (SIAS) is a brief self-report measure designed to assess distress and avoidance related to social interaction. It consists of 20 items and typically requires about 4 minutes to complete.

Respondents rate statements based on their typical experience, supporting a focused appraisal of anxiety that arises during interpersonal exchanges (e.g., initiating, maintaining, or engaging in conversation). The Social Interaction Anxiety Scale (SIAS), attributed to Clarke, J. and Mattick, R., is commonly used in clinical and research settings to quantify symptom severity, inform case formulation, and monitor change over time; results should be interpreted in context and are not diagnostic on their own.
