Peer Support

Peer Support is an individual- and group-level intervention that aims to increase medication adherence among HIV-positive patients. Patients who are HIV-positive, taking antiretroviral therapy (ART), and adherent to their treatment are trained to serve as “peers” for patients who are either ART-experienced or ART-naïve and need additional support.

About Peer Support

Patients who serve as peers provide medication-related social support through group meetings and weekly individual telephone calls. Group meetings are led by peers, who are supervised by agency or clinic program staff. The group meetings are designed to give patients an opportunity to engage face-to-face with their assigned peer, meet other peers and patients who are taking ART and share experiences with the group.

The weekly individual peer phone calls provide more in-depth personal attention and feedback to answer any questions the patient may have felt uncomfortable asking during group meetings. Group discussions focus on identifying barriers to ART adherence and problem-solving strategies to overcome barriers. Group meetings may also focus on life issues that may affect adherence, including disclosure, romantic relationships, substance use, and mental health issues. Based on issues identified by group members, peers may work with program staff to schedule speakers (e.g., nutritionist) to present during group sessions.

Intervention Goals

  • Improve adherence to antiretroviral therapy.
  • Improve clinical outcomes (HIV viral load and CD4 cell count).

Peer Support Training

There is no CDC-supported training currently available for Peer Support. Technical assistance for the implementation of Peer Support is available.

To request technical assistance:

  • CDC’s directly funded health department and CBO partners may request technical assistance by submitting a request in the CBA Tracking System.
  • Organizations not directly funded by CDC may contact their local health department for assistance in submitting a request.

If you have questions or need additional assistance, please contact
