Does the theory-driven program affect the risky behavior of drug injecting users in a healthy city? A quasi-experimental study

Background: The horror of HIV/AIDS as a non-curable, grueling disease is a destructive issue for every country. Drug use, shared needles and unsafe sex are closely linked to the transmission of HIV/AIDS. Modification or changing unhealthy behavior through educational programs can lead to HIV prevention. The aim of this study was to evaluate the efficiency of theory-based education intervention on HIV prevention transmission in drug addicts. Methods: In this quasi-experimental study, 69 male drug injecting users were entered in to the theory- based educational intervention. Data were collected using a questionnaire, before and 3 months after four sessions (group discussions, lecture, film displaying and role play) of educational intervention. Results: The findings signified that the mean scores of constructs (self-efficacy, susceptibility, severity and benefit) significantly increased after the educational intervention, and the perceived barriers decreased (p< 0.001). Also, the history of HIV testing was reported to be 9% before the intervention, while the rate increased to 88% after the intervention. Conclusion: The present research offers a primary founding for planning and implementing a theory based educational program to prevent HIV/AIDS transmission in drug injecting addicts. This research revealed that health educational intervention improved preventive behaviors and the knowledge of HIV/AIDS participants.
