OBJECTIVE
To determine whether an acceptance-based behavioral intervention (ABBI) produces better weight losses than standard behavioral treatment (SBT) among individuals reporting high internal disinhibition.
METHODS
Participants were 162 adults with overweight or obesity (mean BMI 37.6 kg/m ) randomly assigned to ABBI or SBT. Both interventions provided the same calorie intake target, exercise goal, and self-monitoring skills training. SBT incorporated current best practice interventions for addressing problematic thoughts and emotions. ABBI utilized acceptance-based techniques based on Acceptance and Commitment Therapy. ABBI and SBT were compared on weight change and internal disinhibition change over 24 months.
RESULTS
Mixed models analysis showed mean weight loss at 24 months was -4.1% (SE = 0.88) for ABBI and -2.4% (SE = 0.87) for SBT (P = 0.204). Secondary analyses showed that the ABBI group regained less weight from the end of treatment to the final follow-up (4.6 vs. 7.1 kg; P = 0.005), and that a significantly higher proportion of ABBI participants achieved a 5% weight loss (38% vs. 25%; P = 0.038) at 24 months.
CONCLUSIONS
Results suggest that ABBI could be helpful for improving the maintenance of weight loss for individuals who report high internal disinhibition.
目的
确定在报告有高内在去抑制的个体中，基于接纳的行为干预（ABBI）是否比标准行为治疗（SBT）能带来更好的体重减轻效果。
方法
162名超重或肥胖的成年人（平均BMI为37.6kg/m²）被随机分配到ABBI组或SBT组。两种干预都设定了相同的卡路里摄入目标、运动目标，并提供自我监测技能培训。SBT纳入了当前针对解决问题性思维和情绪的最佳实践干预措施。ABBI采用基于接纳与承诺疗法的接纳技术。比较ABBI组和SBT组在24个月内的体重变化和内在去抑制变化。
结果
混合模型分析显示，24个月时ABBI组的平均体重减轻为-4.1%（SE = 0.88），SBT组为-2.4%（SE = 0.87）（P = 0.204）。二次分析表明，从治疗结束到最终随访，ABBI组体重反弹较少（4.6对7.1kg；P = 0.005），并且在24个月时，ABBI组有显著更高比例的参与者体重减轻了5%（38%对25%；P = 0.038）。
结论
结果表明，ABBI可能有助于改善报告有高内在去抑制的个体的体重减轻维持情况。
