Factors Associated with Pre-Service Teachers' Willingness to Teach Opisthorchis viverrini Prevention Education in Lao PDR: A Cross-Sectional Study
This cross-sectional study of pre-service teachers in Lao PDR identifies that female gender, positive attitudes toward the benefits of teaching, supportive professional norms, and high self-confidence are key factors independently associated with a greater willingness to deliver Opisthorchis viverrini prevention education.

In the river valleys of Laos, a microscopic parasite called Opisthorchis viverrini lives inside freshwater fish. When people eat these fish raw or undercooked, a common practice in the region, the parasite enters their bodies. Over time, this infection can damage the liver and bile ducts, sometimes leading to a serious form of cancer. Because the disease spreads through food and daily habits, stopping it requires more than just medicine; it needs education. Schools are a natural place to start, as teachers can reach children and, through them, their families. However, for a school-based program to work, the teachers themselves must be willing to teach about the disease. This willingness depends on what they know, what they believe about the value of the lesson, what they think their colleagues expect of them, and how confident they feel in their ability to explain the topic.
Researchers from Japan and Laos set out to understand what drives this willingness among future teachers. They focused on students at two teacher training colleges in areas where the parasite is common. Using a framework that looks at how people decide to act, the team surveyed hundreds of students to see what factors made them eager to teach prevention lessons. The study found that while knowing facts about the disease is helpful, it is not the most important driver. Instead, the strongest predictor of a teacher's willingness to teach was their confidence in their own ability to do the job.
The study took place in early 2026 at colleges in the provinces of Champasak and Savannakhet. The researchers invited nearly 800 students to fill out an online questionnaire. After removing those who had never heard of the parasite, the final group included 372 students. The team asked these future teachers about their background, their knowledge of the disease, and their feelings toward teaching it. They measured willingness on a simple scale, grouping those who were "willing" or "very willing" into a high-willingness category, and everyone else into a lower-willingness group. The goal was to see which specific traits or beliefs separated the eager teachers from the hesitant ones.
The results showed that most of the future teachers were indeed eager. About 73 percent of the students said they were willing to teach about preventing the parasite. However, the reasons behind this willingness were revealing. The students who felt most confident in their ability to teach the subject were far more likely to say yes. In fact, those who described themselves as confident or very confident were nearly thirteen times more likely to report high willingness than those who felt unsure or not confident at all. This sense of self-assurance, known in the study as perceived behavioral control, was the single most powerful factor.
Other factors also played a significant role. Students who believed that teaching this topic would genuinely benefit schoolchildren were more willing to do it. Similarly, those who felt that their own teachers expected them to promote health education were more likely to step up. Gender also mattered; female students were nearly three times more likely to report high willingness than their male counterparts. Interestingly, the year of study mattered too, with fourth-year students showing less willingness than first-year students, though the reasons for this drop were not fully explained by the data.
Perhaps the most surprising finding was that knowledge alone did not guarantee willingness. While students with higher scores on a test about the parasite were more willing in a simple comparison, this link disappeared when the researchers looked at all the factors together. Once they accounted for confidence, attitude, and perceived expectations, having more facts did not independently make a student more willing to teach. This suggests that simply filling a teacher's head with information is not enough. A student might know everything about the parasite's life cycle but still hesitate to teach if they do not feel capable or supported.
The researchers also looked at whether having previously learned about the disease at college made a difference. They found that simply having been exposed to the topic in the past did not independently increase willingness. This implies that the quality or intensity of that past education matters more than the mere fact that it happened. The study also highlighted gaps in what the students knew. While most knew that eating raw fish was the cause, many were unsure about other details, such as whether insects played a role or whether drinking alcohol with raw fish offered any protection. These misconceptions could be dangerous if passed on to students.
The authors conclude that preparing teachers to fight this disease requires a shift in strategy. It is not enough to lecture future teachers on the facts of the parasite. Teacher training programs need to focus on building confidence through practical experience, such as letting students practice teaching the material. They also need to foster a supportive environment where health education is seen as a shared professional duty. By strengthening the confidence and positive attitudes of future teachers, schools in Laos can better equip the next generation to protect their communities from this persistent health threat.
