Two thirds of the adults in the United States are overweight or obese. Binge eating is a barrier to treatment adherence and sustained weight loss, and can be seen as a form of experiential avoidance. The current study analyzed the impact of binge eating on weight reduction in a previously published study of a 1-day acceptance and commitment therapy (ACT) workshop (N = 83) and the psychological processes accounting for the binge-eating results. ACT participants reported less binge eating, which in turn significantly mediated changes in weight. Mediation analyses also showed that reductions in binge eating were mediated by changes in experiential avoidance. The study suggests that ACT and its targeted processes of change may be particularly relevant to binge eating, and that targeting binging is a possible pathway for improving weight management.
美国成年人中有三分之二超重或肥胖。暴饮暴食是治疗依从性和持续减肥的障碍，可被视为一种体验回避的形式。本研究分析了在之前发表的为期一天的接受和承诺疗法（ACT）研讨会（N=83）的研究中，暴饮暴食对减肥的影响，以及暴饮暴食结果的心理过程。ACT 参与者报告的暴饮暴食行为较少，而体重的变化则显著介导了这种减少。中介分析还表明，暴食行为的减少是由体验回避的变化介导的。该研究表明，ACT 及其针对性的改变过程可能与暴饮暴食特别相关，而针对暴食行为可能是改善体重管理的一种途径。
