Individuals with obesity and binge eating disorder (BED) report poorer weight-related quality of life (WRQOL) compared to individuals with obesity alone. Cognitive behavioral therapy (CBT), the best available treatment for BED, does not consistently produce weight loss or improvements in weight QOL. The purpose of the current study was to examine baseline and longitudinal associations between eating-related and psychosocial variables and dimensions of weight QOL. We examined associations between predictor variables, including body mass index (BMI), eating disorder (ED) psychopathology, and psychosocial factors, in relation to three dimensions of WRQOL among 171 patients whom received CBT for BED. Participants completed interviews and self-report measures at baseline prior to CBT and at end of treatment. At baseline the following associations were significant: BMI, ED psychopathology, and self-esteem were associated with weight-related self-esteem; gender, BMI, and self-esteem were associated with weight-related public distress (i.e., stigma and worry in public because of one's weight); and age, BMI, and ED psychopathology were associated with weight-related physical function. At end of treatment, the following associations were significant: changes in ED psychopathology and coping predicted weight-related self-esteem; changes in coping and self-esteem predicted weight-related public distress; and changes in BMI and subjective binge eating predicted weight-related physical function. Overall, changes in a number of ED and associated symptoms were associated with improvements in WRQOL.
与仅患有肥胖症的个体相比，患有肥胖症和暴饮暴食症（BED）的个体报告的与体重相关的生活质量（WRQOL）较差。认知行为疗法（CBT）是治疗BED的最佳可用疗法，但并不能始终带来体重减轻或体重相关生活质量的改善。本研究的目的是检验与饮食相关和心理社会变量以及体重相关生活质量维度之间的基线和纵向关联。我们在171名接受CBT治疗BED的患者中，研究了预测变量之间的关联，这些预测变量包括体重指数（BMI）、饮食失调（ED）精神病理学和心理社会因素，与WRQOL的三个维度的关系。参与者在CBT治疗前的基线期以及治疗结束时完成了访谈和自我报告测量。在基线期，以下关联具有显著性：BMI、ED精神病理学和自尊与体重相关自尊有关；性别、BMI和自尊与体重相关的公众困扰（即因体重在公共场合的耻辱感和担忧）有关；年龄、BMI和ED精神病理学与体重相关的身体功能有关。在治疗结束时，以下关联具有显著性：ED精神病理学和应对方式的变化预测了体重相关自尊；应对方式和自尊的变化预测了体重相关的公众困扰；BMI和主观暴饮暴食的变化预测了体重相关的身体功能。总体而言，一些ED及相关症状的变化与WRQOL的改善有关。
