Hypochondriasis is highly prevalent in medical settings, has detrimental effects for affected individuals, and is associated with high societal costs. Although cognitive behavior therapy (CBT) has been shown to be effective in the treatment of hypochondriasis, it is not widely available because of a lack of properly trained therapists. Therefore, it is essential to evaluate therapy forms that require less therapist time. The authors investigated the effect and economic impact of group CBT delivered in a psychiatric setting among 24 people with hypochondriasis. A within-group design with prolonged baseline was used, and all participants received 10 weeks of group-based treatment. The primary outcome measures were the Health Anxiety Inventory and the Illness Attitude Scales. Results indicate significant improvement on both measures at posttreatment and 6-month follow-up (Cohen's d = 1.03-1.72). Medical and nonmedical costs were substantially lowered. The authors conclude that group-based CBT delivered in a psychiatric setting is an effective and potentially highly cost-effective treatment for hypochondriasis.
疑病症在医疗环境中极为普遍，对患者有不利影响，且与高昂的社会成本相关。虽然认知行为疗法（CBT）已被证明对疑病症的治疗有效，但由于缺乏经过适当培训的治疗师，因此无法广泛应用。因此，评估需要较少治疗师时间的治疗形式至关重要。作者在精神科环境中对 24 名疑病症患者进行了小组 CBT 的效果和经济影响研究。采用组内设计和延长基线，所有参与者都接受了 10 周的小组治疗。主要的结果测量是健康焦虑量表和疾病态度量表。结果表明，在治疗后和 6 个月随访时，这两个量表都有显著改善（Cohen's d = 1.03-1.72）。医疗和非医疗成本大幅降低。作者得出结论，在精神科环境中进行的小组 CBT 是疑病症的一种有效且具有潜在高成本效益的治疗方法。
