Development of health literacy assessment tool for 9–10 Years old children in Thailand

Abstract

ObjectivesThis study developed psychometric evaluation of an instrument for measuring health literacy among children in Thailand. Study designDevelopment of Health Literacy Assessment Tool for 9–10 Years Old Children in Thailand involved item development. The first step was reviewing literature to pilot-test and generate an item pool. Nine expertise with different disciplines were approached to assess the initial questionnaire. For field-testing, 1650 students with same age group were randomly selected to complete the questionnaire. The psychometric properties of the developed instrument were assessed by an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA). ResultsA total of 50-items were included in exploratory factor analysis indicating 4-dimension solution that jointly explained 36.05% of the variance observed. Confirmatory factory analysis also indicated a good fit of the data for the four-latent structure: access to information (9-items), understanding the information (6-items), appraisal (8-items), and apply the information (9-items) (Chi-square: χ2 = 1530.76), (Goodness-of-Fit Index: GFI = 0.937), (Adjust GFI: AGFI = 0.927), (Standardized root mean-square residual: SRMR = 0.025); (Root mean-square error of Approximation: RMSEA = 0.040), (Comparative-fit-Index: CFI = 0.903) and (Normed-fit-index: NFI = 0.910). Additional analysis for internal consistency observed satisfactory results with overall Cronbach's alpha coefficient of 0.902. The Item-Total Correlation (ITC) was 0.300 (range:0.319 to 0.518) and high validation with value of CVI of 0.87. ConclusionsHealth Literacy Assessment Tool for 9–10 Years Old children (31-item) showed psychometric properties, high validityy and was reliable. Therefore, it is considered as an effective tool to measure the Health Literacy for 9–10 years old children in Thailand.
