Several studies have examined acceptance and commitment therapy's (ACT) effectiveness for addressing physical and psychological distress people with obesity can face. Nevertheless, no review focusing specifically on ACT analysing randomized controlled trials (RCT) has been done up to date in this field. The present systematic review was developed following the PRISMA statement and aimed to examine ACT's effects on weight management and psychological well-being of adults with overweight or obesity. A conjunction of keywords related to ACT and excess weight was searched in four databases (Medline, PubMed, Psycinfo and Scopus) for articles meeting inclusion criteria. The literature search yielded 2,074 papers, and 16 were included in the review, finally. In 71.43% of the studies, ACT was effective to enhance psychological well-being; in 50% effectively targeted process variables and health behaviours related to weight management; in 31.82% of studies, physical variables were improved; and 21.38% of studies showed evidence in favour of ACT for eating behaviour modification. The present review supports ACT for promoting emotional aspects of individuals immersed in such weight-related battles and highlights the benefits of psychological well-being-oriented ACT in the context of obesity treatment. More studies targeting psychological well-being primarily and with longer follow-ups are required.

接受和承诺疗法对超重或肥胖成年人体重管理和心理健康的有效性：系统评价

几项研究已经检验了接受和承诺疗法 (ACT) 在解决肥胖患者可能面临的身体和心理困扰方面的有效性。然而，迄今为止，该领域还没有专门针对 ACT 分析随机对照试验 (RCT) 的评论。本系统评价是根据 PRISMA 声明制定的，旨在检查 ACT 对超重或肥胖成年人体重管理和心理健康的影响。在四个数据库（Medline、PubMed、Psycinfo 和 Scopus）中搜索了与 ACT 和超重相关的关键字组合，以寻找符合纳入标准的文章。文献检索共检索到2074篇论文，最终纳入综述16篇。在 71.43% 的研究中，ACT 对增强心理健康有效；50% 有效地针对与体重管理相关的过程变量和健康行为；在 31.82% 的研究中，物理变量得到改善；21.38% 的研究显示有证据支持 ACT 来改变饮食行为。本综述支持 ACT 促进沉浸在与体重相关的战斗中的个人的情绪方面，并强调了以心理健康为导向的 ACT 在肥胖治疗中的益处。需要更多针对心理健康的研究，并进行更长时间的随访。本综述支持 ACT 促进沉浸在与体重相关的战斗中的个人的情绪方面，并强调了以心理健康为导向的 ACT 在肥胖治疗中的益处。需要更多针对心理健康的研究，并进行更长时间的随访。本综述支持 ACT 促进沉浸在与体重相关的战斗中的个人的情绪方面，并强调了以心理健康为导向的 ACT 在肥胖治疗中的益处。需要更多针对心理健康的研究，并进行更长时间的随访。
