目的 研制痰浊证中医疗效患者自评量表，应用临床调查法多元统计筛选、优化条目。方法 初步编制痰浊证中医疗效患者自评量表，现场调查痰浊证患者及体检健康者，分别从条目的清晰度、变异度、独立性和代表性、内部一致性、敏感性及选项设置等七方面考评条目设置是否合理。结果 本研究共纳入受试者 61例，其中痰浊证患者40例，正常健康者21例。应用以上统计方法对调查结果进行分析、汇总，结合专家意见，“舌苔厚腻”条目不适用于患者进行自评，“纳谷香”条目易产生歧义，且同时被3种统计方法选中删除，故删除“舌苔厚腻”和“纳谷香”两个条目，确定终选量表包含脘痞食少、黏腻、沉重3个维度，食之无味、脘痞腹胀、不思饮食、口腻、咯痰、大便黏、头晕沉、肢体困重、多寐 9个条目结论 通过采用多种统计方法，筛选出独立性、重要性、代表性、稳定性、一致性及敏感性均较好的条目。

Items were selected based on comprehensive analysis from definition, variability, independence and representativeness, internal consistency, sensitivity, and option settings.Results 61 subjects were asked to complete the scale, including 40 patients with phlegm syndrome and 21 healthy subjects. The above statistical methods are used to analyze and summarize the results of the scale. The item of sticky greasy coating is not applicable to the patient"s self evaluation.
