This study aimed to evaluate the efficacy of the educational intervention on adopting preventive behavior against head lice infestation among girl elementary school students.Materials & MethodsThis study was semi-experimental research on elementary school girls in Eyvan, Ilam, Iran, in 2018. Data were collected by a researcher-made questionnaire and checklist behavior. Two girlschr('39') elementary schools were randomly selected from public elementary schools and randomly allocated to the intervention (N=95) and control (N=62) groups. The educational intervention was designed and implemented based on the health belief model in five 30-minutes sessions for the intervention group. One month after the intervention, the students in both groups were evaluated. Data were analyzed using SPSS 22 software via T-test, Chi-square, correlation, and regression.FindingsThe results revealed significant differences in scores of knowledge, HBM constructs, and preventive behaviors in the intervention group after the intervention compared to before the intervention (p<0.05). Self-efficacy was a significant predictor for preventive behaviors of head lice (B= 0.547; p<0.001).ConclusionThe HBM-based health education improves studentschr('39') HBM variables and preventive behaviors.
