The aim of this naturalistic study was to identify pretreatment predictors of response to cognitive behaviour therapy in treatment-seeking patients with binge eating disorder (BED; N = 304). Furthermore, we examined end-of-treatment factors that predict treatment outcome 6 months later (N = 190). We assessed eating disorder psychopathology, general psychopathology, personality characteristics and demographic variables using self-report questionnaires. Treatment outcome was measured using the bulimia subscale of the Eating Disorder Inventory 1. Predictors were determined using hierarchical linear regression analyses. Several variables significantly predicted outcome, four of which were found to be both baseline predictors of treatment outcome and end-of-treatment predictors of follow-up: Higher levels of drive for thinness, higher levels of interoceptive awareness, lower levels of binge eating pathology and, in women, lower levels of body dissatisfaction predicted better outcome in the short and longer term. Based on these results, several suggestions are made to improve treatment outcome for BED patients.
这项自然主义研究的目的是确定寻求治疗的暴饮暴食症（BED；N = 304）患者对认知行为疗法反应的治疗前预测因素。此外，我们还研究了预测6个月后治疗结果的治疗结束时因素（N = 190）。我们使用自我报告问卷评估饮食失调心理病理学、一般心理病理学、人格特征和人口统计学变量。治疗结果使用《饮食失调量表1》的贪食亚量表进行测量。预测因素通过分层线性回归分析确定。几个变量显著预测了结果，其中四个变量被发现既是治疗结果的基线预测因素，也是随访治疗结束时的预测因素：更高的瘦身驱动力水平、更高的内感受性觉知水平、更低的暴饮暴食病理学水平，以及在女性中，更低的身体不满水平预示着短期和长期的更好结果。基于这些结果，我们提出了一些改善BED患者治疗结果的建议。
