Abstract:
Objective To assess the reliability and validity of the effect evaluation index system for health education of coronary heart disease.Methods A total of 306 patients with coronary heart disease in four third-grade and A-level hospitals extacted by convenient sampling method were surveyed.Project analysis,exploratory factor analysis,correlation analysis and so on were applied to analyze and select items.Then the Cronbach's alpha coefficient,test-retest reliability,and content validity of the scale were tested.Then the original system was modified and the eventual system was formed.Results The scale was consisted of 8 first-dimensions and 35 indexes.The Cronbach's α of the total system was 0.832,and the α of subscales were from 0.629 to 0.882.The test-retest reliability of the total system was 0.966,and the testretest reliability of subscales were from 0.848 to 0.942.The S-CVI/Ave of system was 0.99,and the S-CVI/UA of indexes was 0.91.The Pearson correlation coefficient of the indexes with their dimensions were from 0.574 to 0.916,which were higher than the coefficient of the indexes with other dimensions.Factor analysis supported the eight-factor structure of the system,which could explain 65.61％ of the total variance and the factor loading of each index were from 0.430 to 0.938.Conclusions The system is reliable and valid,and can provide a unified reference standard for effect evaluation of health education of coronary heart disease.
