We report on Phase 1 efforts of the Hierarchical Taxonomy of Psychopathology (HiTOP) measurement subgroup tasked with developing provisional scales for the somatoform spectrum and eating disorders. In Study 1, items were written to assess five somatoform spectrum constructs (bodily distress symptoms, conversion symptoms, health anxiety, disease conviction, and somatic preoccupation). Scale development analyses were conducted on 550 university students. The conversion symptom items were too infrequently endorsed and were set aside for Phase 2. Analyses of the other items yielded four scales corresponding closely to their hypothesized structure. In Study 2, we delineated 15 specific feeding and eating disorder constructs. A sample of 400 university students were administered candidate items and several eating disorder questionnaires for criterion validity. Analyses yielded six scales capturing previously described constructs, tapping content related to body image and weight concerns, restricting and purging, cognitive restraint, binging, excessive exercise, and muscle building. Two scales representing additional constructs deemed to be of high clinical import—negative attitude towards obesity and avoidant/restrictive food intake disorder—were retained for Phase 2, for a total of eight scales. Overall, we concluded that Phase 1 had been successful at generating a comprehensive set of provisional scales for inclusion in Phase 2.

我们报告了精神病理学分级分类 (HiTOP) 测量小组的第一阶段工作，该小组的任务是为躯体形式谱和饮食失调开发临时量表。在研究 1 中，编写了项目来评估五个躯体形式谱结构（身体痛苦症状、转换症状、健康焦虑、疾病信念和躯体专注）。对 550 名大学生进行了量表发展分析。转换症状项目很少得到认可，并被留到第 2 阶段。对其他项目的分析产生了四个与其假设结构密切对应的量表。在研究 2 中，我们描述了 15 种特定的进食和进食障碍结构。对 400 名大学生的样本进行了候选项目和几份饮食失调问卷的标准有效性。分析产生了六个量表，捕捉了先前描述的结构，挖掘与身体形象和体重问题相关的内容，限制和净化，认知约束，暴饮暴食，过度运动和肌肉锻炼。代表被认为具有高度临床意义的附加结构的两个量表——对肥胖的消极态度和回避/限制性食物摄入障碍——被保留用于第 2 阶段，共 8 个量表。总体而言，我们得出的结论是，第一阶段成功地生成了一套全面的临时量表，以纳入第二阶段。限制和清除、认知约束、暴饮暴食、过度运动和肌肉锻炼。代表被认为具有高度临床意义的附加结构的两个量表——对肥胖的消极态度和回避/限制性食物摄入障碍——被保留用于第 2 阶段，共 8 个量表。总体而言，我们得出的结论是，第一阶段成功地生成了一套全面的临时量表，以纳入第二阶段。限制和清除、认知约束、暴饮暴食、过度运动和肌肉锻炼。代表被认为具有高度临床意义的附加结构的两个量表——对肥胖的消极态度和回避/限制性食物摄入障碍——被保留用于第 2 阶段，共 8 个量表。总体而言，我们得出的结论是，第一阶段成功地生成了一套全面的临时量表，以纳入第二阶段。
