Effect of theory of planned behavior-based educational intervention on HIV/AIDS preventive behaviors among male barbers

Introduction: Based on the latest estimates of the United Nations Program on HIV/AIDS (UNAIDS), acquired immunodeficiency syndrome (AIDS) is now a public health challenge in Iran, and in 2018, 61,000 people were living with human immunodeficiency virus (HIV), of which 45,000 (75%) were men. This study aimed to evaluate effect of educational intervention based on theory of planned behavior (TPB) on HIV/AIDS preventive behaviors among male barbers. Material and methods: The current quasi-experimental study was conducted in 2019 among 120 male barbers, who were selected using stratified sampling method. Data were collected using a valid and reliable questionnaire based on TPB at baseline and post-intervention. Intervention was designed and performed according to TPB. Data were analyzed with SPSS version 20 using descriptive and inferential methods.Results: Mean age of barbers was 30.41 +/- 8.43 years. At baseline, mean scores of TPB constructs were not significantly different between intervention and control groups (p > 0.05). However, in post-intervention phase, there was a significant difference between two investigated groups in mean scores of TPB constructs (p < 0.05). Conclusions: Findings of the current study showed that educational intervention based on TPB can en-hance knowledge level, perceived behavioral control, and attitude and creation of appropriate subjective norms for formation of behavioral intention and promoting AIDS preventive behavior among barbers.HIV AIDS Rev 2023; 22, 1: 77-83DOI: https://doi.org/10.5114/hivar.2023.124680
