Risk Communication Through Health Beliefs for Preventing Opisthorchiasis-Linked Cholangiocarcinoma: A Community- Based Intervention in Multicultural Areas of Thailand.

Objective: This research aimed to study the effects of the risk communication program through the Cambodian folk song to prevent Opisthorchiasis-linked cholangiocarcinoma (OV-CCA).
Methods: We conducted the quasi-experimental research between August and December 2017 in the Cambodian communities, one-fourth of ethnic minorities residing in multicultural areas of Sisaket Province, Thailand. The samples consisted of 94 equally people divided into experimental group and control group. The experimental group included 47 people at-risk of OV-CCA who received the program for 12 weeks, while the control group received regular services. We collected data by using a questionnaire with a reliability of 0.93. Descriptive and inferential statistics were used for data analysis.
Results: The study indicated that the socioeconomic information of both groups was not different. The mean scores of all issues (health beliefs, social support, and prevention behavior in the experimental group were higher than those of the control group with statistical significance. Closer inspection showed that the mean difference of the health beliefs was 55.61 points (95%CI: 52.39-57.42, p<0.001), social support was 9.09 points (95%CI: 8.12-10.05, p<0.001), and prevention behavior was 6.38 points (95%CI: 5.43-7.33, p<0.001).
Conclusion: Through the Cambodian folk song, the risk communication program by applying the health beliefs and social support to prevent OV-CCA is beneficial for behavior modification in areas with similar cultures.
