Social Interaction Anxiety Scale (SIAS)
How anxious do you feel meeting and talking with people?
Do social situations make you nervous? The SIAS measures the distress you feel when meeting and talking with others. 20 questions, about 5 minutes.
How anxious do you get in social interactions?
Social anxiety is more than just shyness. The SIAS zeroes in on one specific part: the distress you feel meeting and talking with people.
Mattick and Clarke developed it in 1998 as a self-report measure for social interaction anxiety. It covers situations like talking to authority figures, mixing at parties, making small talk, and expressing opinions in a group.
The SIAS has 20 items on a 5-point scale. Three items are reverse-scored. Total scores range from 0 to 80.
Score ranges
- 0-33: Low social anxiety
- 34-42: Moderate / social phobia range
- 43-80: High social anxiety
