Pre-Pilot (R61) WINGS+++: mHealth to Improve MOUD Uptake in Women Experiencing Intimate Partner Violence and PTSD

The goal of this pre-pilot for the clinical trial is to develop a mobile health (mHealth) program called WINGS+++ can help women with opioid use disorder or other substance use disorders who have experienced intimate partner violence. The pre-pilot study will take place in Orange County, New York with n=7 women. . The main questions it aims to answer are: 1. Does WINGS+++ lower non-prescription opioid and other drug use in women? 2. Does WINGS+++ help connect women to treatment for substance use, intimate partner violence, and post-traumatic stress disorder (PTSD)? Researchers will compare WINGS+++ to standard care to see if WINGS+++ works better to lower drug use and link women to helpful services. WINGS+++ is a 3-session program on a mobile device that: * Screens for intimate partner violence, PTSD, and substance use * Offers brief support and referrals based on each woman's needs and preferences * Connects women to a peer navigator who helps link them to services Participants will: * Take part in only the WINGS+++ program for the pre-pilot * Answer survey questions about drug use, intimate partner violence, and PTSD symptoms * Provide biological samples (such as urine or hair) to check for drug use * Share information about the services they have used
