Zambia Healthy Choices Project for Emerging Adults Living With HIV

This project will develop and implement a multi-component intervention using mobile health technology to improve HIV self-management and reduce substance use. Specifically, the investigators will adapt Healthy Choices (HC) to develop mobile HC (mHC) and develop Motivational text messaging (MTM) for Zambian emerging adults living with HIV.
