This study examined the relative effectiveness of VSM and exposure in treating public speaking anxiety in reducing anxiety with a college student. The study employed a single-subject A-B design with parametric variations. Two phases were utilized in this study: baseline (exposure therapy) and treatment (video self-modeling) with a one-month follow-up. Generalization probes were also employed to assess whether or not decreases in PSA would generalize to other settings. Results indicate a significant decrease in public speaking anxiety from both pre- to post-treatment as well as from baseline to exposure. However, these results may be specific to public speaking anxiety, as other forms of anxiety did not result in such decreases. Results from a post-treatment survey indicated that the participant felt that the treatment was beneficial in reducing public speaking anxiety.
