The goal of this clinical trial is to determine the efficacy of a client-center care coordination intervention (C4) in improving pre-exposure prophylaxis (PrEP) adherence in Black men who have sex with men (MSM). The main aims of the study are: 1. Determine the efficacy of C4 for increasing PrEP adherence among Black MSM. 2. Identify the optimal dose of C4 implementation for maximizing its effect on PrEP adherence. 3. Describe the acceptability and feasibility of C4 implementation in community settings. Participants in the clinical trial will be randomized to receive the intervention or standard of care for PrEP in two sites. Researchers will compare administration of C4 to standard of care to see if C4 improves adherence to PrEP. C4 is a longitudinal intervention which provides individualized client-centered HIV prevention and support services designed to address health and psychosocial needs that impact the success of PrEP use and adherence (i.e., co-morbidities, substance use, mental health, housing, etc.). The intervention pulls from the Centers for Disease Control and Prevention (CDC) Comprehensive Risk Counseling and Services (CRCS) and Self-Determination Theory (SDT) to support client-identified HIV prevention goals to promote, adopt, and maintain PrEP use. CRCS is a public health strategy to assist persons in developing behavioral goals to reduce HIV acquisition and transmission. In this intervention, the HIV prevention plan element of CRCS will be the foundation of the C4 intervention. After the initial prevention plan is developed, elements of SDT will be used to implement a client-centered care approach to assist in addressing issues which many arise which impede successful PrEP adherence.
