This study aimed to provide the first comprehensive evidence on the prevalence and predictors of dropout in psychological interventions for pathological health anxiety. A database search in Web of Science, EMBASE, PubMed, Scopus, PsycINFO and the Cochrane Central Register of Controlled Trials identified 28 eligible randomized controlled trials (40 intervention conditions; 1783 participants in the intervention condition), published up to 18 June 2024. Three-level meta-analytic results showed a weighted average dropout rate of 9.67% (95% confidence interval [CI] [6.49%, 14.17%]), with dropout equally likely from treatment and control conditions (odds ratio = 1.07, 95% CI [0.80, 1.44]). Moderator analyses indicated no statistically significant effects of study, participant, treatment or therapist characteristics, except for the country of study. These findings suggest that the average dropout rate is relatively low compared with those reported for other mental health conditions and highlight the importance of considering cultural and societal factors when evaluating treatment adherence. Future research should continue to explore the complex and multifaceted factors influencing dropout to improve the design and implementation of psychological interventions for pathological health anxiety.
本研究旨在提供病理性健康焦虑的心理干预中脱落率的流行情况和预测因素的首个全面证据。在 Web of Science、EMBASE、PubMed、Scopus、PsycINFO 和 Cochrane 对照试验中心注册库中进行数据库检索，确定了 28 项符合条件的随机对照试验（40 个干预条件；干预条件下有 1783 名参与者），这些研究发表于 2024 年 6 月 18 日之前。三级荟萃分析结果显示，加权平均脱落率为 9.67%（95%置信区间 [6.49%，14.17%]），脱落率在治疗和对照组中相等（优势比=1.07，95%置信区间 [0.80，1.44]）。调节分析表明，除研究国家外，研究、参与者、治疗或治疗师特征没有统计学上显著的影响。这些发现表明，与其他心理健康状况报告的脱落率相比，平均脱落率相对较低，强调了在评估治疗依从性时考虑文化和社会因素的重要性。未来的研究应继续探索影响脱落的复杂和多方面因素，以改善病理性健康焦虑的心理干预设计和实施。
