Measuring behavioral responses to a social stressor: Does the Social Performance Rating Scale have utility beyond social anxiety disorder?

The observer-rated Social Performance Rating Scale (SPRS) indexes anxious behaviors exhibited in social contexts. Although the SPRS has been used almost exclusively to study social anxiety disorder (SAD), other emotional disorders are also characterized by heightened responses to social stressors, hinting that the SPRS could serve as a transdiagnostic state measure of behavioral anxiety. To explore this possibility, adults with generalized anxiety disorder or major depressive disorder (n = 105) and adults with no psychopathology (n = 35) delivered a speech to a committee of mock behavioral experts. Behavioral anxiety observed during the speech was rated using the SPRS, then examined in relation to clinical and state measures of anxiety and depression. Contrary to our hypotheses, behavioral anxiety was not associated with clinician- or self-rated anxiety or depression severity. Instead, behavioral anxiety was heightened among individuals who specifically fear and avoid public speaking; who perceived the speech task to be more stressful; and who reported more emotional distress, somatic hyperarousal, and anxious and pessimistic thoughts at the time of the speech. The SPRS is a valid measure of anxious behavior in the many individuals, with and without SAD, who experience acute anxiety in social-evaluative contexts. As behavioral measures are resource-intensive to collect, research is needed to establish whether the SPRS predicts anxious behavior and functional impairment in real-world settings, over and above easier-to-obtain self-report measures.
