RecruitingBehavioural interventionPreconception Intervention for Incarcerated Women With Substance UseThe goal of this pilot trial is to test the feasibility and acceptability as well as efficacy of the adapted intervention, CHOICES-PLEAS (Pregnancy Liberated from Exposure to Alcohol and Substances) among women will illicit polysubstance use participating in a court-mandated jail-based 90-day substance use disorder treatment program. The main questions it aims to answer are: 1. What is the feasibility and acceptability of implementing the CHOICES-PLEAS intervention in a court-mandated jail-based substance use disorder treatment program? 2. Does participation in CHOICES-PLEAS lower the risk of a substance exposed pregnancy at 1 and 3 months after release compared to a control condition? 3. Does participation in CHOICES-PLEAS increase motivation to change substance use and reduce risky sexual behaviors at 1 and 3 months after release compared to a control condition? Participants will receive three one-on-one motivational interviewing sessions and one family planning referral visit during incarceration and one booster session at 1 month after release from jail. Researchers will compare the CHOICES-PLEAS intervention to a control condition to see if participation in the intervention reduces risk of substance exposed pregnancy, increases motivation to change substance use, and reduces risk of risky sexual behaviors.
