这项研究的目的是确定最有可能出现饮食失调的节食者的特征，并评估使用简短问卷提前确定这些节食者的可行性。研究人员确定了2,992名正在节食的年轻女性的一般人群队列。在随后的2年中，有4次向该队列发送了关于饮食习惯和态度的问卷调查。参与者的反应表明，他们已经开发了饮食失调进行了采访，以确定他们的真实情况。对那些后来发生和没有发生饮食失调的人的基线问卷进行比较，以确定预测未来病例状态的特征。在2年的随访中，104名节食者出现了临床严重程度的饮食失调。他们的基线问卷得分在许多方面与那些没有发展成饮食失调的人不同。通过使用三种不同的统计方法选择与发展饮食失调相关的项目。一个简单的病例预测工具的基础上的五个项目之一得分高于最佳临界点的敏感性为71%，特异性为72%（总效率为72%）。在未来2年内将发展为饮食失调的节食者具有明显的特征。通过简单的问卷调查，以合理的效率提前识别他们是可行的。这份问卷可以纳入日常健康评估，从而确定那些处于高风险的人。
The aims of the study were to identify the characteristics of the dieters most at risk of subsequently developing an eating disorder and to evaluate the feasibility of using a brief questionnaire to identify such dieters in advance. A general population cohort of 2,992 young women who were dieting was identified. On four occasions over the subsequent 2 years, this cohort was sent a questionnaire concerning eating habits and attitudes. Participants whose responses suggested that they had developed an eating disorder were interviewed to establish their true case status. The baseline questionnaires of those who did and did not subsequently develop an eating disorder were compared to identify features that predicted future case status. One hundred four of the dieters developed an eating disorder of clinical severity during the 2 years of follow-up. Their baseline questionnaire scores differed in many respects from those who had not developed an eating disorder. Items associated with developing an eating disorder were selected by using three different statistical methods. A simple case-predicting instrument based on one of five items scoring above an optimal cut point had a sensitivity of 71% and a specificity of 72% (overall efficiency of 72%). Dieters who will develop an eating disorder within the next 2 years have distinctive features. It is feasible to identify them in advance with reasonable efficiency with a brief questionnaire. This questionnaire could be incorporated into routine health assessments, thereby identifying those at high risk.
