Building upon prior research regarding mindfulness-based stress reduction interventions, during Phase I, we successfully developed a prototype mobile application (app) for caregivers entitled Mindfulness Based Stress Reduction for African American Caregivers (MBSR-AAC). Based on the Health Stigma and Discrimination Framework, components of the app focus on decreasing stress associated with intersecting sources of stigma, discrimination, and caregiving burdens specifically associated with caregiving for people living with HIV/AIDS (PLWHA). In the present Phase II SBIR study, we will build on Phase I findings to incorporate research-driven enhancements to the app, conduct a feasibility trial of the enhanced app, and conduct a randomized clinical trial to examine the effectiveness of the app in reducing caregiver stress. If proven to be effective, the MBSR-AAC app could have a positive impact on the well-being of African American caregivers that serve as a critical pillar of support for many PLWHA.
