Text Messaging Intervention to Improve Antiretroviral Adherence among HIV-Positive Youth (TXTXT) is an evidence-informed intervention that provides personalized text messages to remind and encourage young people with HIV to take their HIV medication as prescribed. TXTXT clients also receive medication adherence education and counseling, as well as referrals to supportive services when needed. In collaboration with HIV experts and community members, E2i adapted TXTXT for the Ryan White HIV/AIDS Program (RWHAP) and produced a toolkit that provides the resources needed to implement TXTXT with young Black men who have sex with men (MSM) within RWHAP settings and other HIV care organizations.
