中医体质量表应用于术后恶心呕吐风险评估的信度和效度分析

【目的】分析中医体质量表的信度和效度。【方法】采用中医体质量表对2013年3月至10月期间符合入组标准的450例女性妇科腹腔镜手术术后恶心呕吐(PONV)患者的体质类型进行了评价,采用Cronbach’sα系数和因子分析初步分析了量表的信度和效度。【结果】184例(40.9%)女性腹腔镜手术PONV患者兼夹2种及以上偏颇体质,阳虚质和气郁质2个分量表具有较好的内部一致性(Cronbach’sα系数分别为0.815和0.803),平和质最低(Cronbach’sα系数为0.514);因子分析提取9个公因子累计方差解释度仅为48.5%。【结论】中医体质量表还需要结合实际应用后的反馈加以修订。

Analysis of Credibility and Validity of Chinese Medical Constitution Questionnaire in Risk Evaluation of Postoperative Nausea and Vomiting Patients

Objective To preliminarily analyze the credibility and validity of Chinese Medical Constitution Questionnaire(CMCQ).Methods CMCQ was used to investigate the distribution of Chinese medical constitution types of 450 women inpatients with postoperative nausea and vomiting (PONV) after gynecologic laparoscopic surgery from March to October of 2013.Credibility and validity were analyzed by Cronbach's α coefficient and factor analysis.Results Mixed constitution was identified in 184 (40.9％) patients.Cronbach's α coefficient of two dimensions (yang deficiency and qi stagnation) of CMCQ was proper,being 0.815 and 0.803 respectirely,while that of the dimension of harmony type was the lowest (0.514).The total variance explained by 9 common factors extracted from the results of factor analysis was only 48.5％.Conclusion CMCQ may need further revision based on the results of clinical application.
