Treatment Research Investigating Depression Effects on Neuroimmune Targets (TRIDENT)
Florida International University
Summary
The purpose of this randomized controlled trial is to understand how a cognitive-behavioral treatment (a form of psychological treatment) for depression changes the gut microbiome (micro-organisms that regulate the health of the gut), immune system, and the brain functioning in people living with HIV.
Description
The overarching goal of this randomized controlled trial (RCT) is to identify the causal pathways that drive depressive symptoms among people with HIV (PWH). The scientific premise is that evidence-based depression treatment is an innovative, experimental probe to determine the neural substrates of depression and mechanistic relevance of microbiome-gut-brain (MGB) axis changes during and after Cognitive-Behavioral Therapy for Adherence and Depression (CBT-AD) on brain and behavioral function. The proposed causal pathway is that reductions in depressive symptoms following the delivery of CBT-AD…

Interventions
- BehavioralCognitive-Behavioral Therapy for Adherence and Depression (CBT-AD)
CBT-AD is a behavioral intervention administered either in person or via Zoom. Each session lasts approximately 50 minutes. Participants will receive up to 12 individually delivered sessions over 4 months. Participants receive up to three individually delivered booster sessions through 6 months.
- BehavioralAntiretroviral Therapy (ART) Adherence Counseling
This treatment involves a single session integrating CBT for depression with CBT for adherence following our "Life-Steps" approach.
