A community clinic randomly assigned 120 adults with social anxiety disorder to either 12 weeks of group cognitive-behavioral therapy or 12 weeks of individual cognitive-behavioral therapy. Both formats produced significant reductions on the Liebowitz Social Anxiety Scale, with no statistically significant difference between formats. The group format cost roughly one-third as much per patient.

- Ccheck_circle
Group CBT may offer comparable efficacy to individual CBT for social anxiety at lower cost.

Cost savings prove that group CBT has greater clinical effectiveness.
Explanation
Equivalent outcomes plus lower cost support cost-effectiveness, not superior effectiveness. The other options overreach or contradict the equivalence finding.
