Abstract
This study aimed to investigate the effect of role-playing and lecture on improving the attitudes of the Khorramabad suburban population toward the human immunodeficiency virus (HIV). In 2019, 270 people aged 18 and above participated in a randomized controlled trial in Khorramabad, Iran. Individuals were randomly assigned to one of three groups: role-playing, lecture, or control. To collect data before and after the intervention, we used a standard HIV knowledge and attitude questionnaire. Before the educational intervention, three marginalized groups' attitudes toward HIV were stigmatized. After the intervention, the attitudes of both the role-playing and lecture groups improved significantly relative to the control group (P<0.0001); there was no significant difference between the two methods (P>0.05). The correlation between attitude and knowledge scores was positive (P<0.0001). This study demonstrates that education is a fundamental pillar of improving attitudes toward people living with HIV (PLHIV) and can reduce stigma against them, thereby increasing their desire to disclose their condition and seek medical care.
