许多研究诊断面试采用跳过规则，例如一些问题只根据先前问题的答案提出。在大规模流行病学研究的背景下，跳过规则通过减少评估所需的时间、金钱和参与者负担而对研究可行性非常重要。然而，当问题被跳过时，对信息丢失的理解却很少。本研究检查了相对患病率，临床意义，以及评估DSM-IV轴I障碍结构化临床访谈（SCID-I）中跳过的进食障碍症状模式所需的额外时间，以了解以下跳过规则的成本和收益。数据来自两阶段队列样本（N=400）的第二阶段，其中SCID-I进食障碍模块在不遵循跳过规则的情况下进行管理。对结果进行加权，以纠正抽样框架。超过三分之一的受试者认可了如果遵循跳过规则会被遗漏的症状。未捕获的症状模式与心理社会障碍增加有关，评估所有症状所需的额外时间平均为每位参与者1.8分钟。SCID-I和类似的诊断工具遗漏了具有临床意义的症状模式，这表明使用此类工具的流行病学研究低估了精神障碍的患病率和公共卫生影响。
Many research diagnostic interviews employ skip rules, such that some questions are only asked based on answers to prior questions. In the context of large-scale epidemiological studies, skip rules are important to study feasibility by reducing the time, money, and participant burden required for assessment. However, less is understood about information lost when questions are skipped. This study examines the relative prevalence, clinical significance, and additional time required to assess eating disorder symptom patterns skipped in the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to understand the costs and benefits of following skip rules. Data come from the second stage of a two-stage cohort sample (N=400) in which the SCID-I eating disorders module was administered without following skip rules. Results were weighted to correct for the sampling framework. Over a third of subjects endorsed symptoms that would have been missed had skip rules been followed. Uncaptured symptom patterns were associated with increased psychosocial impairment, and the additional time required to assess all symptoms averaged 1.8 minutes per participant. Clinically significant symptom patterns are missed by the SCID-I and similar diagnostic tools, suggesting that epidemiologic studies using such instruments underestimate the prevalence and public health impact of mental disorders.
