What this trial studies

This pilot trial aims to evaluate the feasibility, acceptability, and efficacy of the CHOICES-PLEAS intervention among incarcerated women with substance use disorders. Participants will receive three motivational interviewing sessions and a family planning referral during their 90-day court-mandated treatment program. The study will assess whether this intervention reduces the risk of substance-exposed pregnancies and increases motivation to change substance use behaviors. A total of 90 women will be recruited and randomized into intervention and control groups over a 2.5-year period.

Who should consider this trial

Good fit: Ideal candidates are English-speaking women capable of becoming pregnant who have a history of substance use and vaginal sex with male partners.

Not a fit: Patients who have undergone permanent sterilization or are using long-acting reversible contraceptives will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce the incidence of substance-exposed pregnancies among incarcerated women.

How similar studies have performed: While similar interventions have been explored, this specific approach targeting incarcerated women with substance use disorders is relatively novel.
