Theory-based interventions in STIs/HIV Prevention: A systematic review of the literature in Iran

Background: Various theory-based interventions (TBIs) have been done to prevent STI/HIV. The current study aimed at reviewing the TBIs for STI/HIV prevention in Iran.    Methods: We systematically searched 6 English and Persian electronic databases to identify TBIs conducted for STI/HIV prevention in Iran. General searches were conducted using PubMed MeSH terms. Articles were included if they were interventional and conducted using models and theories, aimed at reducing the risk of STIs, were quasi-experimental or experimental, and if their full text was available.    Results: Overall, 1042 studies were found. Finally, 13 original studies met our inclusion criteria. The findings indicated that HBM and TPB were the most frequently used theory/models. High school students and drug abusers were the most common target groups in the included studies.    Conclusion: The results revealed that the majority of the conducted TBIs contained a methodological weakness. Conducting randomized controlled trials is needed to evaluate the effectiveness of the TBIs.
