Integrating a Brief Behavioral Intervention Into Case Management for Mothers With Perinatal Substance Use Disorder: Nonrandomized Pilot Feasibility Study

PHF can be feasibly delivered within an existing intensive case management program for perinatal SUD, with early signals of mental health improvement across both intervention and control groups. Future adequately powered randomized controlled trials should investigate the effectiveness of brief behavioral interventions within perinatal SUD case management programs, optimal delivery timing, and the potential to enhance mental health care integration for high-risk perinatal populations.
