Description

The Social Phobia Scale is a 20-item self-report measure of fear of being scrutinised or observed during routine activities such as eating, drinking and writing. A typical question in this scale is “I get nervous that people are staring at me as I walk down the street“. This measure is useful in tracking symptoms of social phobia and self consciousness over time.

Validity and Reliability

The SPS has demonstrated discriminant validity, with the scale distinguishing between clinical presentations of anxiety (i.e. social phobia, agoraphobia and simple phobia), and between social phobic and non-clinical (student and community) samples (Mattick & Clarke, 1998). Convergent validity of the SPS is also apparent, as the scale correlates highly with established measures of social anxiety (e.g. FNES and SADS) The SPS has high internal consistency and high test-retest reliability at 4 and 12 weeks. This measure also responds as expected (i.e. total scores decrease) to treatment of scrutiny fears (Mattick & Clarke, 1998).

Interpretation

A raw total score ranging from 0-80 is given as output, with higher scores indicating higher anxiety about being observed or scrutinised. The total raw score is converted into two percentiles, comparing the client to a social phobia sample (n = 243) and an adult community sample (n = 315) (Mattick & Clarke, 1998). A percentile of 50 compared to the social phobia group represents typical symptom severity for someone who has been independently diagnosed with social phobia. A percentile of 50 in the community sample represents the typical score among the population, and is indicative of a normal level of social fear.
