Abstract:
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.
