Binge eating disorder (BED) is associated with medical and psychiatric issues commonly seen and managed in primary care; however, the disorder typically goes undetected as there are no assessment tools feasible for use in primary care. The objective was to examine the validity of the VA Binge Eating Screener (VA-BES), a single-item screening measure for binge eating.
The sample consisted of 116 veterans referred to a primary care-based weight management program. Participants had a mean age of 61.66years (SD=8.73) and average BMI of 37.90 (SD=7.35). Frequency of binge eating ranged from zero to 21 episodes per week. The prevalence of BED was 7.76%. All participants completed the Questionnaire of Eating and Weight Patterns - Revised (QEWP-R) to assess for BED. They also completed the VA-BES, and measures of disordered eating and depressive symptoms.
The VA-BES was compared to the QEWP-R to determine the sensitivity, specificity, positive predictive value, and negative predictive value for each cutpoint. Analyses revealed one cutpoint (≥2 binge eating episodes per week) maximized these values, demonstrated excellent agreement with the QEWP-R (χ=24.79, p<0.001), and had significant associations with other variables commonly associated with binge eating.
This study demonstrates the utility and validity of a single-item measure to screen for binge eating in primary care. The item can quickly and easily identify binge eating, thus facilitating referral to treatment and potentially subsequent improvements in related medical and mental health comorbidities treated in primary care.
暴饮暴食症（BED）与基层医疗中常见且需处理的医学和精神问题相关；然而，该疾病通常未被发现，因为在基层医疗中没有可行的评估工具。目的是检验退伍军人事务部暴饮暴食筛查量表（VA-BES）这一用于筛查暴饮暴食的单项筛查工具的有效性。
样本包括116名被转诊至基层医疗体重管理项目的退伍军人。参与者的平均年龄为61.66岁（标准差=8.73），平均体重指数为37.90（标准差=7.35）。暴饮暴食的频率从每周零次到21次不等。暴饮暴食症的患病率为7.76%。所有参与者均完成了修订版饮食与体重模式问卷（QEWP-R）以评估暴饮暴食症。他们还完成了VA-BES以及饮食失调和抑郁症状的测量。
将VA-BES与QEWP-R进行比较，以确定每个切点的敏感性、特异性、阳性预测值和阴性预测值。分析显示，一个切点（每周≥2次暴饮暴食发作）使这些值最大化，与QEWP-R显示出极好的一致性（χ=24.79，p<0.001），并且与其他通常与暴饮暴食相关的变量有显著关联。
本研究证明了在基层医疗中使用单项测量工具筛查暴饮暴食症的实用性和有效性。该项目能够快速、轻松地识别暴饮暴食症，从而便于转诊接受治疗，并可能改善基层医疗中治疗的相关医学和心理健康合并症。
