Before the intervention, immediately and two months after the intervention, the two groups completed the questionnaire. The control group received no intervention. Results: Data analysis showed that the differences between the two groups was statistically significant immediately and two months after the intervention (p<0.05). In experimental group the changes in the mean score of knowledge, attitude and performance of nurses before, immediately and two months after the intervention were significant (p<0.05), but in the control group, only the changes in the mean score of performance were significant (p<0.05). Conclusion: The results showed that the HBM-based intervention is effective in promoting nurses' knowledge, attitude, and performance in preventing nosocomial infections. hence, periodical and in-service HBM-based training programs on preventing nosocomial infections are recommended to be held for nurses.
