Abstract:
ObjectiveTo develop a reliable and valid health self-management competence assessment questionnaire for primary and secondary school students in Shanghai, so as to provide an effective tool to evaluate and improve their health management competencies. MethodsBased on the theory and process of scale development, an initial item pool was formed. After two rounds of Delphi consultation with 22 experts in related fields, assessment indicators suitable for evaluating the health self-management ability of Shanghai primary and secondary school students were determined. A total of 666 students were selected using stratified cluster sampling method to carry out the survey. The questionnaire content was refined and items were screened for reliability and validity analyses. ResultsAfter the two rounds of Delphi expert consultation, the original three-dimensional structure (individual management behaviors, personal health cognition and self-management environment) was revised into four dimensions: self-health cognition, self-health skills, self-will quality and self-action level. The initial 50 items were reduced, merged, or newly created, yielding a final 30-item questionnaire. Expert response rates for the two rounds of Delphi consultation were 86.36% and 90.91%, respectively, with an expert authority coefficient of 0.91. The KMO value was 0.936 and Bartlett’s sphericity test yielded a P value of <0.001, indicating that the questionnaire demonstrated good construct validity. The results of internal consistency testing showed that the overall Cronbach’s α coefficient was 0.932, and the split-half reliability coefficient was 0.920. The Cronbach’s α coefficient of each dimension ranged from 0.716 to 0.884, and the split-half reliability coefficient ranged from 0.733 to 0.900. Finally, an evaluation scale with 30 items across 4 dimensions was constructed. ConclusionThe health self-management competence evaluation scale for primary and secondary school students in Shanghai demonstrates good homogeneity and high reliability. It can be used as a tool for evaluating the health self-management competency of primary and secondary school students in Shanghai and provide theoretical support for targeted health interventions.
