Keywords:
Health literacy Scale, Health literacy in elderlyAbstract
Based on the physical changes for elderly into the decay of the body, these changes can affect to easily get illness, such as diabetes mellitus, hypertension, and depression. Health literacy is an important factor on developing health behavior and preventing diseases among elderly. Based upon the reviews, there has been conducted the health literacy’s scale, but no research study has been specifically designed for a Thai-version of the health literacy questionnaire for self-care (HLQFSC) among elderly. The purpose of this study was to develop and validate a Thai-version instrument measuring health literacy for self-care among elderly that covered its reliability and validity. The HLQFSC among elderly living in Bangkok was developed from Sorensen et al. (2012)’s framework and empirically validated the content by five experts for elderly concept, as well as reliability with Cronbach’s alpha coefficient as a pilot study. The HLQFSC was examined by descriptive statistics, Pearson’s correlation coefficient, and confirmatory factor analysis.
The results showed that there were 600 elderly. Most participants aged between 60-65 years of old, and 69.2% of the participants were male. The mean of total health literacy was 3.58. The final version of the HLQFSC had 22 items, with the Cronbach’s alpha coefficient of 0.950. The confirmatory factor analysis showed that the model was fitted with acceptable fit using most criteria (χ2 = 656.32, df = 205, CFI = 0.99, GFI = 0.91, TLI = 0.98, RMSEA = 0.061), and also the 4-factors model was confirmed: 1) Assess 2) Understand 3) Appraise, and 4) Apply. The Thai-version of the HLQFSC had good psychometric properties. It can be used for assessing health literacy for self-care among elderly.
