Summary
The Brief Social Phobia Scale (BSPS) reliably and validly measures social phobia symptoms. This observer-rated scale is sensitive to treatment effects, making it a valuable tool for clinical evaluation.
Area of Science:
- Psychiatry
- Clinical Psychology
- Psychometrics
Background:
- Social phobia is a common anxiety disorder.
- Assessing social phobia symptoms requires reliable and valid instruments.
- The Brief Social Phobia Scale (BSPS) was developed for this purpose.
Purpose of the Study:
- To evaluate the psychometric properties of the Brief Social Phobia Scale (BSPS).
- To determine the reliability, validity, and sensitivity to change of the BSPS.
Main Methods:
- The BSPS, an 18-item observer-rated scale, was administered to 275 social phobia patients.
- Psychometric analyses included test-retest reliability, internal consistency, correlations with other scales, and factor analysis.
- Sensitivity to change was assessed in a treatment trial.
Main Results:
- The BSPS demonstrated excellent test-retest reliability and internal consistency.
- Fear and avoidance subscales correlated well with total scores; the physiological subscale did not.
- The BSPS showed significant correlations with anxiety and disability scales and was sensitive to treatment effects.
Conclusions:
- The Brief Social Phobia Scale (BSPS) is a reliable, valid, and sensitive measure for assessing social phobia.
- The BSPS is a useful tool for clinical evaluation and treatment monitoring in social phobia.
