Physical inactivity is a key risk factor for non-communicable diseases, and there is a need for interventions to increase the adoption and maintenance of regular physical activity. Interventions based on Acceptance and Commitment (ACT) have shown promise for promoting a range of health behaviours, including physical activity. The aims of this review were to (1) determine the effectiveness of ACT interventions for physical activity; and (2) identify the ACT processes, behaviour change techniques (BCTs) and intervention characteristics associated with ACT interventions. Eight electronic databases were searched for ACT interventions that aimed to increase physical activity. Seven eligible studies were included in the systematic review, and ACT processes, Behaviour Change Techniques and other intervention components and characteristics of the included interventions were coded. Six studies were randomised controlled trials that were included in a random-effects meta-analysis, which indicated small-to-moderate effects on physical activity (SMD = 0.32, 95% CI (0.07, 0.57), = 0.01). ACT interventions show promise for increasing physical activity, but very few of the 'active ingredients' of ACT interventions could be characterised as BCTs. Future development of ACT interventions for physical activity should attempt to describe and name the ACT processes targeted by the intervention, and the BCTs used to target those processes.
身体活动不足是非传染性疾病的一个主要风险因素，因此需要采取干预措施来提高人们对定期身体活动的采纳和维持。基于接纳与承诺疗法（ACT）的干预措施已显示出在促进一系列健康行为（包括身体活动）方面的潜力。本综述的目的是：（1）确定 ACT 干预措施对身体活动的有效性；（2）确定与 ACT 干预措施相关的 ACT 过程、行为改变技术（BCT）和干预特征。我们在八个电子数据库中搜索了旨在增加身体活动的 ACT 干预措施。有 7 项符合条件的研究被纳入系统综述，对包括的干预措施中的 ACT 过程、行为改变技术和其他干预组成部分和特征进行了编码。6 项研究是随机对照试验，被纳入随机效应荟萃分析，结果表明 ACT 干预对身体活动有小到中等的影响（SMD=0.32，95%CI（0.07，0.57），p=0.01）。ACT 干预措施在增加身体活动方面显示出一定的前景，但 ACT 干预措施的“有效成分”中很少能被描述为 BCT。未来开发用于身体活动的 ACT 干预措施，应尝试描述和命名干预措施针对的 ACT 过程，以及用于针对这些过程的 BCT。
