Abstract:

Objective To develop an intrinsic capacity health literacy scale for older adults,in order to provide a more integrated,comprehensive,and simple assessment tool for health management of the elderly,and to improve the theoretical system of health literacy with the goal of healthy aging. Methods The first draft of the intrinsic capacity health literacy scale was constructed through the literature analysis and the Delphi method. From May to August 2024,638 elderly residented from communities in Yangzhou and Taizhou cities in Jiangsu Province were selected for a survey to conduct reliability and validity analysis on the preliminary draft of the scale. Results The intrinsic capacity health literacy scale for older adults consisted of three dimensions:functional health literacy,interactive health literacy,and critical health literacy,with a total of 36 items. Exploratory factor analysis extracted three common factors,with a cumulative variance contribution rate of 70.031%. Validation factor analysis confirmed the good fit of the modified scale model. The item-level content validity index varied between 0.867 and 1.000,while the scale-level content validity index at 0.974. Cronbach's alpha coefficient for the overall scale was 0.968,and the folding coefficient reached 0.853. Conclusion The intrinsic capacity health literacy scale for older adults has high reliability,specificity,and comprehensiveness,which can provide a basis for improving the level of intrinsic capacity health literacy of the elderly and developing intervention programs.
