Summary View help for Summary
This study is part of the Seek, Test, Treat and Retain (STTR) Collaboration Project that involved over twenty studies in the fields of HIV and drug abuse. All studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. As part of STTR Collaboration Project, the studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g., Demographic characteristics, Mental Health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study.
Using a randomized controlled study design, this study tested the efficacy of an abstinence-reinforcing CM intervention compared with a control condition (performance feedback) on HIV viral load (VL) suppression. The intervention CM group could receive up to $1320 in vouchers over the 16-week intervention based on drug-free urine. Participants were followed for 28 weeks (44 visits), with research visits occurring twice weekly during the Baseline Period (weeks 1-4, visits 1-8) and Intervention Period (weeks 5-20, visits 9-40), then every two weeks during the Post-Intervention Period (weeks 21-28, visits 41-44).

Study Purpose View help for Study Purpose
The purpose of this study is to test whether an abstinence-reinforcing contingency management intervention improves HIV viral load suppression in HIV-infected drug users receiving drug and HIV treatment, by following two aims:
- Aim 1: To test the efficacy of a 16-week abstinence-reinforcing contingency management intervention on VL suppression.
- Aim 2: To examine mechanisms of achieving VL suppression with our abstinence-reinforcing CM intervention.
Study Design View help for Study Design
This is a randomized controlled study of 16-week CM intervention vs Performance feedback:
- Intervention: The 16-week CM intervention consisted of participants receiving vouchers exchangeable for goods and services (worth up to $1320) contingent on achieving abstinence, defined as urine free of cocaine and opiates.
- Control: Performance feedback consisted of providing feedback to participants with informational slips of paper indicating results of urine tests.
To ensure an equal distribution of key factors between the study groups, the research team stratified randomization by site (DoSA clinics, ID clinic, other clinics) and cocaine use (yes, no). Randomization was conducted in blocks to ensure equal randomization over short periods of time to avoid period effects.
Sample View help for Sample
Participants were recruited using active (i.e. via medical staff, letters) and passive (i.e. flyers, advertisements, word-of-mouth) recruitment strategies from Einstein's Division of Substance Abuse (DoSA), Montefiore's community clinics, Montefiore's ID Clinic, the surrounding community and local newspapers.
