Current screening instruments for eating disorders are cumbersome to administer and have not been validated in primary care populations. We compared the performance characteristics of 2 screening tools, the SCOFF clinical prediction guide, and a new set of questions, the Eating disorder Screen for Primary care (ESP), using the Questionnaire for Eating Disorders Diagnosis as the independent standard, in 104 consecutive patients from a primary care practice and 129 university students. Twelve percent of the combined population had an eating disorder. One or no abnormal responses to the ESP ruled out an eating disorder (likelihood ratio [LR] 0.0), whereas 3 or more abnormal responses ruled one in (LR 11). The SCOFF questions were less sensitive than predicted (1 or no abnormal responses, LR 0.25), but were as effective at ruling in an eating disorder (3 or more abnormal responses, LR 11).
目前用于饮食失调的筛查工具使用起来很繁琐，且尚未在初级保健人群中得到验证。我们将两种筛查工具——SCOFF临床预测指南和一套新的问题——初级保健饮食失调筛查量表（ESP）的性能特征进行了比较，以饮食失调诊断问卷作为独立标准，对来自一家初级保健机构的104例连续患者和129名大学生进行了研究。合并人群中有12%患有饮食失调症。对ESP有1个或没有异常反应可排除饮食失调症（似然比[LR] 0.0），而有3个或更多异常反应则可确诊（LR 11）。SCOFF问题的敏感性低于预期（1个或没有异常反应，LR 0.25），但在确诊饮食失调症方面同样有效（3个或更多异常反应，LR 11）。
