Popis: Abstract Background HIV prevention knowledge levels are low in sub-Saharan Africa. In our efficacy study, the Mzake ndi Mzake (Friend-to-Friend; hereafter Mzake) 6-session peer group intervention, delivered by health workers, improved HIV prevention knowledge and other outcomes in Malawi. To expand HIV prevention approaches, this implementation study tested whether the intervention remained effective when implemented by trained community volunteers. HIV prevention knowledge findings are presented. Methods Using a stepped wedge design, three communities implemented the Mzake program sequentially in randomly assigned order. Repeated surveys assessed outcomes, and participants served as controls until they completed the program. At Time 2, Community 1 became the intervention group, and at Time 3, Communities 1 and 2 were the intervention group. HIV prevention knowledge, the primary outcome, was assessed through two indicators: UNAIDS comprehensive knowledge (UNAIDS Knowledge), defined as correctly answering five HIV prevention questions (Yes/No), and a 9-item HIV/PMTCT Knowledge Index (number correct). Multivariate generalized estimating equation logistic regression (UNAIDS Knowledge) and mixed-effects regression models (HIV/PMTCT Knowledge Index) were used to assess knowledge controlling for five sociodemographic factors. Results In bivariate analyses of UNAIDS Knowledge, more persons answered correctly in the intervention group than the control group at Time 2 (56.8% vs. 47.9%, p
