To examine whether changes in different aspects of dietary restraint in obese patients with binge eating disorder (BED) participating in a treatment study predict outcomes.
Fifty obese patients with BED in a randomized controlled study of orlistat administered with cognitive-behavioral therapy, guided-self-help (CBTgsh) completed dietary restraint measures at baseline, during- and post-treatment, and three-month follow-up.
Change in the restraint scale of the Eating Disorder Examination-Questionnaire did not predict binge abstinence or 5% weight loss. Increased flexible restraint subscale of the Three Factor Eating Questionnaire (TFEQ) during treatment significantly predicted binge abstinence at post-treatment and three-month follow-up and 5% weight loss at post-treatment. Change in the rigid restraint subscale of the TFEQ predicted binge abstinence at post-treatment.
Our findings clarify further pathologic and adaptive aspects of restraint and suggest the importance of enhancing flexible restraint in order to improve both binge eating and weight loss outcomes.
研究参加治疗研究的暴食症（BED）肥胖患者在饮食抑制的不同方面的变化是否可以预测治疗结果。
在奥利司他联合认知行为治疗、指导自助（CBTgsh）的随机对照研究中，50 名肥胖伴暴食症患者在基线、治疗期间和治疗后以及三个月随访时完成饮食抑制措施。
饮食紊乱问卷的抑制量表变化不能预测暴食症戒除或体重减轻 5%。治疗期间三因素饮食问卷（TFEQ）的灵活抑制子量表增加显著预测治疗后和三个月随访时的暴食症戒除和治疗后体重减轻 5%。TFEQ 的刚性抑制子量表的变化预测治疗后的暴食症戒除。
我们的发现进一步阐明了抑制的病理和适应性方面，并表明增强灵活抑制对于改善暴食和体重减轻结果的重要性。
