Adaption of the STAIR-NT Trauma Intervention for Polysubstance Populations

During this 36-month R34 trial, eight study phases are proposed to adapt an evidence-based post traumatic stress disorder (PTSD) intervention (STAIR-NT) and layer it into a methadone maintenance treatment (MMT) program (START Treatment and Recovery centers) in New York City for use among individuals engaged in stimulant-opioid polysubstance use. The study aims to adapt STAIR-NT to a massed treatment schedule. Once an adapted protocol is complete, it will be tested for feasibility, acceptability, and short-term polysubstance and PTSD symptomology outcomes in a pilot randomized control trial (RCT) of 80 participants. Participants who screen eligible and consent will be randomized 1:1 to the adapted STAIR-NT intervention or treatment as usual (TAU) using randomization blocks of two and two and four via a computer-generated randomization sequence. Participants assigned to the intervention will receive the adapted massed delivery of STAIR-NT by trained counselors.
