From the AHRQ summary: Participants were strongly receptive to the messages and intervention. There were four areas in which a statistically significant change was noted during the study, including adherence to medication, knowledge of HIV, social support, and a reduction in the number of sexual partners. Additionally, a significant decrease in viral load was noted, as was a marginally significant increase in CD4 counts, which is an indication of the number of white blood cells which fight infections and their count indicates the stage of HIV or AIDS in a patient.
