Effectiveness of educational technology on human immunodeficiency virus/AIDS prevention: randomized clinical trial.

The study measured knowledge only, not condom use, PrEP or PEP use, or HIV infection. The sample came from evening school students aged 50 or over in Recife, so it may not apply to older adults in clinics or other settings. Randomization was by school cluster, and students were recruited by convenience, which can leave differences between groups. The groups differed at baseline in age and years of schooling, so the groups were not perfectly comparable. Follow-up was only 30 days, and the authors noted possible courtesy bias because tests were given before and after a playful game. The protocol originally planned people aged 60 and over, but the study included people aged 50 and over.

Do not conclude that the board game prevents HIV or changes unprotected sexual practices. It improved knowledge scores on a 12-item test, and the paper states that knowledge alone may not lead to safer sex.
