目的：确定基于接受的行为治疗（ABT）是否会导致比标准行为治疗（SBT）更大的体重减轻，以及干预专家的专业知识或参与者对饮食线索的敏感性是否会调节治疗效果。最近的研究表明，长期的体重控制效果不佳是由于在坚持体重控制行为的失误，并坚持可能会提高通过加强SBT与接受为基础的行为strategies.Design and Methods：超重参与者（n = 128）被随机分配到40周的SBT或ABT。两组都有明显的体重减轻，当专家进行管理时，在治疗后（13.17% vs. 7.54%）和6个月随访（10.98% vs. 4.83%）时，ABT组的体重减轻显著高于SBT组。此外，64%接受专家ABT的人（SBT为46%）在随访时保持至少10%的体重减轻。适度分析显示，在随访中，ABT比SBT在那些可能更容易受到饮食线索影响的人中具有强大的优势。对于基线抑郁症的参与者，随访时ABT的体重减轻率为11.18%，SBT为4.63%;其他比较分别为10.51%和6.00%（情绪化进食），8.29%和6.35%（去抑制），9.70%和4.46%（对食物线索的反应）。中介分析产生部分支持理论化的食物相关的心理接受作为一种机制的action.Conclusions：结果提供了强有力的支持，为纳入接受为基础的技能到行为减肥治疗，特别是在那些更大程度的抑郁症，对食物环境的反应，去抑制，情绪化饮食，特别是当干预措施提供了由体重控制专家。
Objective: To determine whether acceptance-based behavioral treatment (ABT) would result in greater weight loss than standard behavioral treatment (SBT), and whether treatment effects were moderated by interventionist expertise or participants' susceptibility to eating cues. Recent research suggests that poor long-term weight-control outcomes are due to lapses in adherence to weight-control behaviors and that adherence might be improved by enhancing SBT with acceptance-based behavioral strategies.Design and Methods: Overweight participants (n = 128) were randomly assigned to 40 weeks of SBT or ABT.Results: Both groups produced significant weight loss, and when administered by experts, weight loss was significantly higher in ABT than SBT at post-treatment (13.17% vs. 7.54%) and 6-month follow-up (10.98% vs. 4.83%). Moreover, 64% of those receiving ABT from experts (vs. 46% for SBT) maintained at least a 10% weight loss by follow-up. Moderation analyses revealed a powerful advantage, at follow-up, of ABT over SBT in those potentially more susceptible to eating cues. For participants with greater baseline depression symptomology, weight loss at follow-up was 11.18% in ABT versus 4.63% in SBT; other comparisons were 10.51% versus 6.00% (emotional eating), 8.29% versus 6.35% (disinhibition), and 9.70% versus 4.46% (responsivity to food cues). Mediation analyses produced partial support for theorized food-related psychological acceptance as a mechanism of action.Conclusions: Results offer strong support for the incorporation of acceptance-based skills into behavioral weight loss treatments, particularly among those with greater levels of depression, responsivity to the food environment, disinhibition, and emotional eating, and especially when interventions are provided by weight-control experts.
