Data Set: Adhara Peer Intervention

This study aimed to assess the impact of a peer intervention programme in the hospital setting to improve the health-related quality of life (HRQoL) of people recently diagnosed with HIV infection. A quasi-experimental single-group study with pre- and post-measurements was conducted. The peer intervention programme consisted of four sessions that took place at the following times: (1) the day of diagnosis, (2) the day when the results of the analyses were collected and ART (antiretroviral therapy) began, (3) 1 month after the start of ART, and (4) 4 months after the start of ART. The dependent variables were HRQoL and several psychological predictors of HRQoL.
