Effect of Self-Care Behavior Modification Program of The Group at Risk Liver Fluke Infection in The People of Huai Phai Subdistrict, Khong Chiam District, Ubon Ratchathani Province

Abstract

This quasi-experimental research aimed to evaluate the effectiveness of a self-care behavior modification program for individuals at risk of liver fluke infection. The study involved 96 participants with identified risk behaviors for liver fluke infection. They were divided into an experimental group (n=48) from Huai Phai sub-district, Khong Chiam district and a control group (n=48) from Nong Phoe Noi sub-district in Ubon Ratchathani province. The program integrated the Health Belief Model with specific self-care behavior modification activities tailored to this at-risk population. Data were collected via questionnaires between December 2024 and March 2025. Statistical analysis included paired-sample t-tests to assess within-group changes and ANCOVAs to compare knowledge, attitudes, and preventive behaviors related to liver fluke disease between groups while controlling for covariates. The findings revealed that, post-intervention, the experimental group showed a statistically significant increase in knowledge about liver fluke disease compared to pre-intervention (p<.001, Mean diff=2.062, 95% CI=1.247, 2.88). Similarly, mean attitude scores regarding liver fluke disease (p<.001, Mean diff=5.77, 95% CI=-4.21, 7.22) and mean preventive behavior scores (p<.001, Mean diff=3.41, 95% CI=2.09, 4.73) also significantly improved. These results indicate that the self-care behavior modification program for residents at risk of liver fluke infection in Huai Phai sub-district was effective in achieving its objectives. This program holds potential for adaptation and implementation in other high-risk areas where raw fish consumption is prevalent. It can effectively enhance knowledge, transform attitudes, and reduce risky behaviors, thereby contributing to the prevention and reduced incidence of liver fluke infection, a primary cause of cholangiocarcinoma.
