This study compares different versions of mirror exposure (ME), a body image intervention with research support. ME protocols were adapted to maximize control and comparability, and scripted for delivery by research assistants. Female undergraduates (N=168) were randomly assigned to receive mindfulness-based (MB; n=58), nonjudgmental (NJ; n=55), or cognitive dissonance-based (CD, n=55) ME. Participants completed the Body Image Avoidance Questionnaire (BIAQ), Body Checking Questionnaire (BCQ), Satisfaction with Body Parts Scale (SBPS), Beck Depression Inventory-II (BDI-II), and Eating Disorders Examination Questionnaire (EDE-Q) at pre-treatment, post-treatment, and 1-month follow-up. Mixed models ANOVAs revealed a significant main effect of time on all measures, and no significant time by condition interaction for any measures except the SBPS. Post-hoc analysis revealed that only CD ME significantly improved SBPS outcome. Results suggest that all versions of ME reduce eating disorder risk factors, but only CD ME improves body satisfaction.
本研究比较了不同版本的镜像暴露（ME），这是一种具有研究支持的身体意象干预措施。ME 方案经过调整，以最大限度地控制和可比性，并由研究助理编写脚本进行交付。女性本科生（N=168）被随机分配接受正念为基础的（MB；n=58）、非评判的（NJ；n=55）或认知失调为基础的（CD，n=55）ME。参与者在治疗前、治疗后和 1 个月随访时完成了身体意象回避问卷（BIAQ）、身体检查问卷（BCQ）、身体部位满意度量表（SBPS）、贝克抑郁量表-II（BDI-II）和饮食失调检查问卷（EDE-Q）。混合模型方差分析显示，所有测量指标均有显著的时间主效应，除 SBPS 外，任何指标均无时间与条件的交互作用。事后分析表明，只有 CD ME 显著改善了 SBPS 的结果。结果表明，所有版本的 ME 都能降低饮食失调的风险因素，但只有 CD ME 能提高身体满意度。
