Background and Objectives: While all students are vulnerable to injuries, such vulnerability may even be higher in the deaf and hard-of-hearing students. Therefore, this study evaluated a health belief model-based educational program to prevent school injuries among deaf and hard-of-hearing high school students. Materials and Methods: This quasi-experimental study was conducted on all deaf and hard-ofhearing students who attended two special schools in Hamadan (Iran) during 2014. They were randomly assigned to either the intervention group (n = 23) or the control group (n = 27). Data were collected using a self-report questionnaire containing items on demographic characteristics, constructs of the health belief model, and knowledge and preventive behaviors. In both groups, the questionnaires were filled out through interviews before and two months after the intervention. The intervention included distributing booklets and holding five educational sessions. Data were analyzed with paired t, independent t, chi square, and Fisher's exact tests in SPSS 16. Results: After the educational intervention, the mean scores of knowledge (P=0.002), preventive behaviors (P=0.001), and constructs of the health belief model, i.e. perceived severity (P=0.001), perceived benefits (P=0.001), self-efficacy (P=0.001), and cues to action (P=0.001), were significantly higher in the intervention group than in the control group. Conclusion: According to our findings, an educational intervention based on the health belief model can promote behaviors to prevent school injuries among deaf and hard-of-hearing students.
