To examine the operating characteristics of the Patient Health Questionnaire eating disorder module (PHQ-ED) for identifying bulimia nervosa/binge eating disorder (BN/BED) or recurrent binge eating (RBE) in a community sample and to compare true positive (TP) versus false positive (FP) cases on clinical validators.
Two hundred and fifty-nine screen-positive individuals and a random sample of 89 screen negative cases completed a diagnostic interview. Sensitivity, specificity, and positive predictive value (PPV) were calculated. TP and FP cases were compared using t-tests and Chi-square tests.
The PHQ-ED had high sensitivity (100%) and specificity (92%) for detecting BN/BED or RBE, but PPV was low (10 or 19%). TP and FP cases did not differ significantly on frequency of subjective bulimic episodes, objective overeating, restraint, on BMI, and on self-rated health.
The PHQ-ED is recommended for use in large populations only in conjunction with follow-up questions to rule out cases without objective bulimic episodes.
研究患者健康问卷进食障碍模块（PHQ-ED）在识别社区样本中神经性贪食症/暴食障碍（BN/BED）或反复暴食（RBE）的操作特征，并比较临床验证者中真正阳性（TP）与假阳性（FP）病例。
259 名筛查阳性个体和 89 名随机筛查阴性个体完成了诊断访谈。计算了敏感性、特异性和阳性预测值（PPV）。使用 t 检验和卡方检验比较 TP 和 FP 病例。
PHQ-ED 对 BN/BED 或 RBE 的检测具有高敏感性（100%）和特异性（92%），但 PPV 较低（10 或 19%）。TP 和 FP 病例在主观暴食发作频率、客观暴食、限制、BMI 和自我评估健康方面无显著差异。
PHQ-ED 仅建议在大人群中与后续问题一起使用，以排除无客观暴食发作的病例。
