This study determines the impacts of an educational intervention based on a health belief model.<br> <strong>Methods</strong>: This quasi-experimental study was conducted on patients with type 2 diabetes using convenience sampling. They were randomly assigned to experimental (n=55) and control groups (n=55). A standard questionnaire was used to collect the data. The healthy behaviors were measured again after 3 and 6 months, and the data analysis was performed using the SPSS software, version 20.<br> <strong>Results</strong>: The mean value of perceived susceptibility boosted in the intervention group from 18.94 before the training to 22.90 and 22.3 after 3 and 6 months of the intervention, respectively. The mean score perceived severity increased in the intervention group to 31.30 and 31.42 after 3 and 6 months of the intervention, respectively. Meanwhile, the mean score of perceived benefits increased in the intervention group from 10.06 before the training to 11.61 and 13.32 after 3 and 6 months of the intervention, respectively. The mean score of perceived barriers decreased in the intervention group from 19.50 before the training to 13.35 and 12.21 after 3 and 6 months of the intervention, respectively. The mean score of perceived self-efficacy boosted in the intervention group from 24.16 before the training to 29.44 and 29.48 after 3 and 6 months of the intervention, respectively. The mean value of cues to action boosted in the intervention group from 20.15 before the training to 22.2 and 23.2 after 3 and 6 months of the intervention, respectively.<br> <strong>Conclusion</strong>: The results demonstrated the importance of designing educational programs based on the health belief model constructs over 3 and 6 months in adopting healthy behaviors by subjects with type 2 diabetes.&nbsp;<br> <br> <strong>Corresponding author:&nbsp;</strong>Parvaneh Isfahani, Email: p.isfehani@gmail.com​​​​​​​<br> <u>You can also search for this author in:</u>&nbsp;<a href="https://pubmed.ncbi.nlm.nih.gov/?term=%28Parvaneh+Isfahani%5BAuthor%5D%29+AND+%28Zabol+University+of+Medical+Sciences%5BAffiliation%5D%29">PubMed</a>,&nbsp;<a href="https://scholar.google.com/citations?hl=en&user=FK25GHoAAAAJ">Google Scholar</a></span></span><br> &nbsp;</div> Education, Health belief model, Type 2 diabetes 417 426 http://jrh.gmu.ac.ir/browse.php?a_code=A-10-2106-1&slc_lang=en&sid=1 Mohammad Sarani sarani@Zbmu.ac.ir 100319475328460030523 100319475328460030523 No Department of Public Health, School of Public Health, Zabol University of Medical Sciences, Zabol, Iran.
