Outline
To develop and validate a health literacy assessment scale for junior high school students, providing an effective tool for evaluating and monitoring health literacy among Chinese adolescents.
Based on school health education policy documents, a health literacy assessment framework was constructed, comprising five horizontal and four vertical dimensions. From May to June and August to September in 2024, the framework was refined through Delphi expert consultations and focus group discussions, leading to the development of the Health Literacy Assessment Scale for Junior High School Students. In September 2024, a convenience sample of 625 students from three junior high schools in Beijing and Tianjin completed the questionnaire. Item analysis, reliability, and validity tests were conducted to evaluate the scale.
The recovery rate for two rounds of expert consultation questionnaires was 100%. The expert authority coefficients (Cr) were 0.86 and 0.87 respectively (both >0.70), with Kendall W values of 0.34 and 0.27 (P < 0.05). The focus group discussions followed a rigorous structure, and after multiple rounds of item screening and revision, the version 3.0 of the junior high school students' health literacy assessment scale was developed, comprising 57 items. Three items that failed to meet the comprehensive screening criteria were preliminarily removed, and the final scale contained 54 items. The scale demonstrated excellent reliability, with an overall Cronbach's α coefficient of 0.92 and split-half reliability of 0.93. Confirmatory factor analysis [χ2/df=2.094, root mean square error of approximation (RMSEA)=0.042, comparative fit index (CFI)=0.911, Tucker Lewis index (TLI)=0.907] indicated good model fit indices.
The preliminary development of the health literacy assessment scale for junior high school students follows a rigorous item screening process with well-designed dimensions, demonstrating good reliability and validity, thus serving as an appropriate evaluation tool for adolescent health literacy.
