Brief Acceptance-Based Retention Intervention for Newly Diagnosed HIV Patients

Study Overview
=================
Brief Summary
-----------------
The overall aim of this program of research is to test a newly developed intervention, Acceptance-Based Behavior Therapy (ABBT), to improve HIV patients' commitment to medical care. The purpose of the proposed project is to establish the efficacy of ABBT and examine its mechanisms of action. To achieve the specific aims, the investigators will conduct a randomized clinical trial (n = 270), with two treatment arms: ABBT vs. an attention-matched HIV education control condition.

Detailed Description
-----------------
Drop-out rates from medical clinics in the first months following linkage to HIV care are as high as 50%, with 31-46% of patients dropping out after the first visit. People Living with HIV (PLWH) who are not consistently retained in care are at risk for: delayed antiretroviral treatment (ART) initiation, reduced ART adherence, unsuppressed viremia, and mortality. Moreover, poor retention means effective ART cannot be leveraged to prevent further HIV transmission. The objective of this study is to conduct a fully powered, randomized controlled trial (RCT) to assess the efficacy of a brief, 2-session acceptance-based behavioral therapy (ABBT) intervention to enhance retention in HIV care. The aims of this proposal are: (1) To test, in a 2-arm RCT, the efficacy of the ABBT intervention on retention in care and virologic suppression (primary outcomes); and, ART adherence, disclosure of HIV status, perceived social support, HIV stigmatization (secondary outcomes), relative to an Enhanced-Treatment-as-Usual condition; and, (2) To examine the degree to which retention in HIV care and virologic suppression are mediated by (a) increased HIV acceptance (and decreased HIV experiential avoidance) and (b) increased willingness to disclose HIV status. The sample will consist of 270 HIV patients who are new to care.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Acceptance-Based Behavior Therapy (ABBT)<br>The 2-session ABBT will be delivered in person at session 1 and by telephone at session 2. | Behavioral: Acceptance-Based Behavior Therapy (ABBT)<br>* Acceptance-Based Behavior Therapy (ABBT) In the first session, the interventionist will introduce the concept of acceptance and its possible benefits in the context of life values and participant-identified barriers to retention in care. Interventionists will help participants identify potential challenges to acceptance, including disclosure concerns. At the second session, participants will practice acceptance-based coping skills and a behavioral plan will be developed to target barriers identified in the first session. These discussions will help the participant clarify how best to align their values with decisions on how to manage their HIV.<br>|
| Placebo Comparator: Enhanced-Treatment-as-Usual (ETAU)<br>In addition to receiving treatment-as-usual at the clinic, ETAU participants will receive a 2-session program of HIV education. | Behavioral: Enhanced-Treatment-as-Usual (ETAU)<br>* ETAU will consist of two brief sessions lead by study interventionists, performed at the same times and by same methods as ABBT. Topics of education include safe sex practices, review of treatment options, and review of HIV-related indices of health.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Retention in medical care | Objective data from participants' electronic health records will be obtained to examine how many medical appointments they attended in the past year at their HIV treatment clinic. Participants will be deemed as sufficiently retained if they attend at least 3 medical visits during this period. | 52 weeks | 
| Virologic suppression | Objective data from participants' electronic health records will be obtained to examine their viral load, which is a blood-based measure of the amount of HIV viruses in the person's body. If participants are not currently retained in medical care and blood sample results are not available in their electronic health record, they will submit 1-3ml of blood at each assessment through the study's research phlebotomist. | 52 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Self-Rating Scale Item (SRSI) - Antiretroviral Treatment adherence | Self-report data of participants' HIV antiretroviral treatment adherence will be obtained with the SRSI. Scores range from 0 to 5, which correspond to very poor to excellent medication adherence. | 52 weeks | 
| Brief HIV Disclosure and Safer Sex Self-Efficacy Scales (BHD) | The BHD HIV disclosure subscale will be used to assess for willingness to make informed disclosure and for actual disclosure of HIV status. Scores range from 8-32, with higher scores indicating increased willingness to disclose. | 52 weeks | 
| The Multidimensional Scale of Perceived Social Support (MSPSS) | The MSPSS will be used to measure perceived social support. Scores range from 1-84, with higher scores indicating greater perceived social support. | 52 weeks | 
| HIV Stigma Scale (HSS) | The HSS will be used to measure self-reported experiences, fear, and perception of stigmatization due to being HIV+. Scores range from 6-24, with lower scores indicating less fear or concern about stigmatization. | 52 weeks |
