90 名社交恐惧症（社交焦虑症）患者参加了一项随机对照试验，并完成了认知行为团体治疗、没有明确认知干预的暴露团体治疗或等待名单控制条件。两种治疗在减少社交焦虑方面均优于等待名单组，但在治疗后并无差异。从测试前到测试后，估计社会成本的变化介导了两种治疗条件的治疗变化。然而，只有接受认知行为治疗的参与者从事后到 6 个月的随访显示出持续的改善，这与从测试前到测试后估计社会成本的降低有关。这些结果表明，认知干预可以更好地维持治疗收益，这是通过估计社会成本的变化来调节的。
Ninety individuals with social phobia (social anxiety disorder) participated in a randomized controlled trial and completed cognitive-behavioral group therapy, exposure group therapy without explicit cognitive interventions, or a wait-list control condition. Both treatments were superior to the wait-list group in reducing social anxiety but did not differ from one another at postlest. Changes in estimated social cost mediated treatment changes in both treatment conditions from pre- to posttest. However, only participants who received cognitive-behavioral therapy showed continued improvement from postlest to 6-month follow-up, which was associated with a reduction of estimated social cost from pretest to posttest. These results suggest that cognitive intervention leads to better maintenance of treatment gains, which is mediated through changes in estimated social cost.
