A Transdiagnostic Treatment to Improve Biomedical and Syndemic Outcomes in People Living With HIV.

People living with HIV (PLWH) experience a range of co-occurring psychosocial stressors, mental health symptoms, and structural barriers (e.g., "syndemics") that can impair their ability to adhere to medical recommendations for treatment. This has consequences for their health and the health of others as nonadherence increases the likelihood of unsuppressed HIV viral load, and therefore the ability to transmit HIV to others. Transdiagnostic treatment, or treatment not focused on a single mental health condition, can efficiently address a range of mental health problems by skills training to reduce symptoms. Additionally, cognitive behavioral and problem-solving approaches can be used to address larger, structural factors by helping individuals navigate systemic challenges using evidence-based skills. This article describes the development of a transdiagnostic treatment for PLWH and illustrates the application of the treatment through case examples. This treatment might be appropriate for integration into an HIV clinic or within an outpatient setting when working with a patient who is experiencing syndemic conditions and living with HIV.
