The main aim of this project was to explore the efficacy of Acceptance and Commitment Therapy (ACT)‐based educational course in different formats (i.e., pure and guided self‐help with different durations, and guided self‐help with and without access to a discussion forum) for body shape dissatisfaction. Two randomized controlled studies (RCT) were carried out. In the first RCT, the participants were randomized to a 12‐ or 16‐week guided self‐help, a 16‐week pure self‐help, or a waitlist control condition. In the second RCT, the efficacy of 12‐week guided self‐help with or without access to a discussion forum was investigated. ACT‐based self‐help resulted in promising improvements in body shape dissatisfaction, and modest effects on general health indicators (i.e., symptom of depression, self‐esteem, satisfaction with life, and quality of life). The findings also showed no additional effects of support, access to the online discussion forum, and longer duration of self‐help, suggesting the 12‐week self‐help with or without support is a viable option for reducing body shape dissatisfaction.

两项基于接受和承诺治疗的身体形状不满意教育课程疗效的随机对照试验

该项目的主要目的是探索以接受和承诺疗法（ACT）为基础的教育课程在不同形式下的有效性（即，具有不同持续时间的纯指导性自助服务，以及有或没有获得性服务的指导性自助服务）。讨论论坛）以获取身体形状上的不满意。进行了两项随机对照研究（RCT）。在第一个RCT中，将参与者随机分为12周或16周的指导性自助，16周的纯自助或等待名单控制条件。在第二个RCT中，研究了有或没有进入讨论论坛的12周指导自助服务的有效性。基于ACT的自助有助于改善人们对身体形状的不满，并对一般健康指标产生适度的影响（例如，抑郁症状，自尊，生活满意度和生活质量）。
