Patients are randomly assigned to either a comprehensive cognitive-behavioral treatment for social phobia (n=43), a performance-based exposure treatment for public speaking anxiety without cognitive intervention (n=43), or a waitlist control group (n=43). Clinician ratings, behavioral tests, cognitive assessments, subjective ratings, and physiological measures are employed to determine the degree of therapeutic gains in various social phobia domains. The main hypothesis is that perceived emotional control will mediate treatment outcome and generality of effectiveness independent of the specific treatment condition.
