摘要
目的研制冠心病常见证候要素自评辨识量表,并对量表进行评价。方法通过文献研究及专家咨询法形成冠心病常见证候要素自评量表的条目池,通过专家咨询法、临床调查法,结合频数法、相关系数法、Cronbach’sα系数法、因子分析法联合进行条目筛选,以主客观联合赋权方法确定条目的权重,通过受试者工作特征曲线法确定诊断阈值,通过Cronbach’sα系数、因子分析法等对量表进行信效度检验。结果制订的冠心病常见证素自评辨识量表共计6个证候要素36个条目,包括血瘀3个条目、痰浊9个条目、气滞7个条目、气虚5个条目、阴虚6个条目、阳虚6个条目,诊断阈值分别为1.000、45.300、36.400、66.600、33.900、30.500;量表各维度的重测信度系数均>0.7,各维度的内部一致性信度系数为0.540~0.848;因子分析方面,提取每一个公因子载荷系数>0.4的变量,结果与量表的条目设置完全吻合,累计方差贡献率为53.822%。结论冠心病常见证候要素自评辨识量表信度及效度良好,具有一定的科研与临床应用价值。
Objective To develop and evaluate the Self-rating Identification Scale for Common Syndromic Elements of Coronary Heart Disease.Methods The item pool of the Self-rating Identification Scale for Common Syndromic Elements of Coronary Heart Disease was formed through literature review and expert consultation.Items were screened by combining frequency,correlation coefficient,Cronbach's α coefficient and factor analysis.Subjective and objective weighting was used to determine the weight of items,and diagnostic threshold was determined by receiver operator characteristic curve.Cronbach's α coefficient and factor analysis were used to test the reliability and validity of the scale.Results The Self-rating Identification Scale for Common Syndromic Elements of Coronary Heart Disease had a total of 6 syndrome elements and 36 items.It included 3 items of blood stasis,9 items of phlegm,7 items of Qi stagnation,5 items of Qi deficiency,6 items of Yin deficiency,and 6 items of Yang deficiency,and the diagnostic thresholds were 1.000,45.300,36.400,66.600,33.900,and 30.500 respectively.The test-retest reliability coefficients of each dimension of the scale were all greater than 0.7,and the internal consistency reliability coefficients of each dimension were 0.540 to 0.848.In the factor analysis,each variable with a common factor load coefficient greater than 0.4 was extracted,and the results were completely consistent with the scale entry settings.The cumulative variance contribution rate was 53.822%.Conclusions The reliability and validity of the Self-rating Identification Scale for Common Syndromic Elements of Coronary Heart Disease are good,and it has scientific research and clinical application value.
