About Social Anxiety

The Social Interaction Anxiety Scale (SIAS) is a twenty-item measure which assesses fears of general social interaction, corresponding to the DSM-III-R descriptions of Social Phobia — Generalised type. The Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale were developed as a companion set of measures by Mattick and Clarke in 1998. The scales correlated well with established measures of social anxiety, but were found to have low or non-significant (partial) correlations with established measures of depression, state and trait anxiety, locus of control, and social desirability. The scales were found to change with treatment and to remain stable in the face of no treatment. It appears that these scales are valid, useful, and easily scored measures for clinical and research applications.

When should you consider this assessment?

If several of these experiences have been present for two weeks or more and are affecting your daily life — work, sleep, relationships — a screening assessment is a good first step to understand what you are going through.

How the assessment works

About 5 minutes. Each one asks how often you have experienced something recently. You can go back and change any answer before you submit, and you will see every answer on a review screen first.

What happens after?

You will get a patient-friendly report: a severity band, a breakdown of which areas weigh heaviest, key observations from your answers, and clear next steps. If it would help to talk to someone, we will suggest therapists who work with social anxiety.

How it works

Three steps, about 5 minutes, and nothing you cannot undo.
