Effectiveness of peer assisted learning in improving HIV knowledge, attitude, and perception among community health workers

Background: Community health workers (CHWs) act as a bridge between community and clinical care in caring for HIV patients. This study aimed to evaluate the effectiveness of peer education in improving HIV knowledge, attitude, and perception of CHWs in Babol, Iran in 2019. Methods: This was a quasi-experimental study conducted among CHWs in the health centers of Babol, Iran. The city was divided into two areas of the North and the South according to the geographical map. Then, based on the list of the health centers in each of the areas, one health center was randomly selected and assigned to either the experimental or the control group. Results: Following peer education, all study variables including knowledge score, attitude, and perception about HIV-related issues significantly improved in the experimental group compared to the pre-intervention phase (P=0.002, P=0.02, and P=0.00 respectively). The most significant change was in misconception score with a approximately large effect size (0.78), presenting an increase of 95.53% from 15 to 29.33 after the intervention, while attitude and knowledge respectively presented 85.04% and 81.07% increase with a smaller effect size of 0.57 and 0.52. Conclusion: In the study peer education proved to be an effective strategy in improving the knowledge, attitudes, and perception of CHWs concerning HIV/AIDS. Therefore, the peer-to-peer training model can fill a critical gap in the training of CHW based on the idea that not only do the CHWs themselves need to enhance their knowledge of related topics but they also need to train others. In turn, this will result in providing cost-effective health promotion and prevention services in a more culturally appropriate manner.
