HIV knowledge and its correlation with the Undetectable = Untransmittable slogan in Brazil.

Knowledge about HIV transmission and prevention is a necessary step for adopting preventive behaviors. We assessed HIV knowledge and its correlation with the perceived accuracy of the "Undetectable = Untransmittable" (U=U) slogan in an online sample with 401 adult Brazilians. Overall, 28% of participants showed high HIV knowledge level.

Development and Evaluation of Short-Form Measures of the HIV/AIDS Knowledge Assessment Tool Among Sexual and Gender Minorities in Brazil: Cross-sectional Study.

Background: In theoretical models of health behavior, knowledge about disease transmission and self-protective behaviors are conceptualized as important drivers of behavior change. Several studies conducted in Brazil point to an unfortunate convergence of sexual and gender minority (SGM) populations with low levels of HIV knowledge and younger age, lower education, engagement in higher-risk sexual behavior, and never having tested for HIV. Measures to assess level of HIV knowledge have been previously published, including the 12-item HIV/AIDS Knowledge Assessment (HIV-KA) tool.

[Patient's understanding of information on antiretroviral therapy: an application of the latent trait model].

The aim of this study was to develop a score to determine the level of understanding regarding information on antiretroviral therapy (ART) among patients initiating treatment. This was a cross-sectional analysis based on interviews with HIV patients in outpatient public referral centers (Belo Horizonte, Minas Gerais State, Brazil). The score for patients' understanding of their medicines was obtained using a latent trait model, estimated by the Item Response Theory, based on the concordance between each patient answer and the written prescription.
