The Development of Health Literacy Tool for behavior the Opisthorchiasis Prevention in population.

Abstract

This research is research and development aimed to develop a tool to measure health literacy for behavior the Opisthorchiasis prevention in population. Thai people aged 15 years and above was to collect data between January- May 2018, by 1) Review literature about health literacy and Opisthorchiasis. 2) Develop a tool to measure health literacy for behavior the Opisthorchiasis prevention in population. 3) Item relevance was assessed by five experts and improve a tool. 4)The pre-testing of internal consistency was conducted by sample 30 of Thai people aged 15 years and above. 5) Develop a tool 2 time by conducted sample 220 of Thai people aged 15 years and above first time to quality testing a tool by analyze discrimination, consistency reliability and construct validity by analyze confirmatory factor analysis (CFA) and calculate the appropriate intersection point to be used to classify health literacy.
The result: A tool 59 item showed index of Item objective congruency(IOC) between 0.6 – 1 and IOC = 0.89. Internal consistency reliability = 0.88, discrimination between 0.20-0.96, the difficulty of the test between 0.40-0.93, KR-20 = 0.67, consistency reliability between 0.52 – 0.91 and a tool 45 item. Analyze confirmatory factor analysis showed the model was fitted to the empirical data Chi-Square =15.091 df= 8 p-value = 0.0574 (ค่า Chi-Square/df = 1.8864) RMSEA = 0.063 SRMR =0.036 CFI =0.977 TLI = 0.956. The higher factor loading sub-factors were knowledge (b=1.00) and clarified variance 45.9% (R2 = 0.459) ,inferior was self management (b=0.896) was clarified variance 49.4% (R2 = 0.494) and media literacy (b=0.835) was clarified variance 48.6% (R2 = 0.486). Calculate the appropriate intersection point to be used to classify high health literacy  52.50, sensitivity = 59.3, specificity =30.2 % area of receiver operating characteristic curve (ROC) =0.42 % (95%CI = 0.32-0.52).
Conclusion: A tool to measure health literacy for behavior the Opisthorchiasis prevention in population which developed accuracy in content, structure, and accuracy Can be used to assess the health literacy of Thai people aged 15 years and up at the health and national level there should be a study of relationships, knowledge in each element. And if this tool will be used with other groups, further should be development.
