OBJECTIVE
To develop an effective measure of the symptoms of eating disorders for use in community surveys.
METHOD
A branched eating disorders instrument for administration by notebook computer was evaluated as a screen in 487 teenage schoolgirls. High scorers and a stratified sample of low scorers were evaluated in a second-stage interview with the Eating Disorders Examination (EDE).
RESULTS
The Branched Eating Disorders Test (BET) proved to have exceptional validity coefficients (sensitivity 100%, specificity 99%, positive predictive value 70%).
DISCUSSION
This pilot validation suggests that the BET largely overcomes the problems of earlier instruments of limited screening utility when applied to community samples.
目的
开发一种用于社区调查的有效饮食失调症状测量方法。
方法
对一种通过笔记本电脑进行施测的分支式饮食失调量表作为筛查工具在487名青春期女学生中进行评估。高分者和低分者的分层样本在第二阶段接受饮食失调检查（EDE）访谈评估。
结果
分支式饮食失调测试（BET）被证明具有极高的效度系数（敏感性100%，特异性99%，阳性预测值70%）。
讨论
这项初步验证表明，当应用于社区样本时，BET在很大程度上克服了早期筛查效用有限的工具所存在的问题。
