儿童胃肠积热评价性量表的研制

目的研制儿童胃肠积热评价性量表。方法由专业人员采集了453例研究对象的临床信息,共包括38个症状及体征。采用5种方法进行条目筛选,包括基于经典测量理论的离散趋势法、相关系数法、克朗巴赫系数法及因子分析法和项目反应理论。最终保留至少4种方法保留的条目,并结合专业知识形成量表。结果最终形成量表共有26个条目,包括面赤、唇红、咽红肿、舌红、舌苔黄、手足心热、脉数、脉滑、恶热、口臭、口鼻气热、口渴喜冷饮、食欲异常、腹痛、矢气臭、大便次数减少、大便干结、排便费力、大便臭、小便色黄、夜间汗出、夜卧不安、烦躁、鼻痂、易呼吸道感染和饮食不节则加重。其中11个条目为二分类变量,以有或无分级;15个条目为四分类变量,以频率或程度分级。结论形成了以胃肠积热为核心的评价量表,为胃肠积热与相关疾病的研究奠定了基础。

Designing of evaluation scale for Gastrointestinal Heat Retention Syndrome in children

Objective To develop the evaluation scale for Gastrointestinal Heat Retention Syndrome(GHRS) in children. Methods 453 children were enrolled and 38 symptoms and signs of the subjects were collected by medical professionals. Classical Test Theory and Item Response Theory were used to select items. Items were selected through five statistical methods including classical test theory of discrete trends analysis, correlation coefficient analysis, Cronbach’s αcoefficient analysis and factor analysis, as well as item response theory. The items which were tested to be acceptable according to 4 or 5 methods would be kept and enlisted in the evaluation scale under the guidance of professional knowledge. Results The evaluation scale consisted of 26 items, including red complexion, red lips, pharyngeal redness and swelling, red tongue, yellow tongue fur, feverish feeling in palms and soles, rapid pulse, slippery pulse, aversion to heat, halitosis, hot mouth and nasal breath, thirst with preference for cold drinks, abnormal appetite, abdominal pain, smelly flatus,reduced frequency of defecation, dry stool, difficult defecation, smelly stool, yellow urine, sweating at night, restless sleep at night, vexation and irascibility,nasal crust, susceptibility to respiratory tract infection, and symptoms worsened after improper diet. There were 11 binary variables and 15 quadruple variables graded by frequency or severity degree. Conclusion The evaluation scale for GHRS in children is developed, which can be used in the study of GHRS and GHRS-related diseases in children.
