This research aimed to develop a risk assessment tool for hepatitis B and C infections to support disease prevention and control efforts. The research involved three stages: firstly, developing instrument; secondly, testing; and finally, usability assessment. The study samples included individuals aged 30 years and older who lived in the areas of local administrative organizations within Health Region 7. Qualitative data were analyzed using content analysis and quantitative data using descriptive and inferential statistics. The developed assessment tool contained 12 questions related to risks for hepatitis B and C infections, and 12 questions designed to assess the participants’ knowledge and understanding of the diseases. The Item-Objective Congruence (IOC) values ranged from 0.67 to 1.00, and the KR-20 reliability coefficient of an assessment tool was 0.84. For hepatitis B infection prediction, the area under the ROC curve was 69.33% (95% CI: 0.60-0.80), with a sensitivity of 68.00% (95% CI: 65.42-70.61), specificity of 66.30% (95% CI: 63.63-68.92), and accuracy of 66.30%. For hepatitis C prediction, the ROC curve was 60.20% (95% CI: 0.80-1.00), with a sensitivity of 75.40% (95% CI: 74.33-6.64), specificity of 41.50% (95% CI: 40.11-42.82), and accuracy of 41.80%. In addition, the developed risk assessment tool demonstrated acceptable validity and reliability and was rated highly satisfactory by users, with an average satisfaction score of 4.34 (SD=0.76).
