A Computer-Assisted Brief Motivational Intervention for Smoking During Pregnancy: The Healthy Pregnancy Project (HPP)
In Brief
A Phase 2 clinical trial evaluating Computer-delivered brief intervention (5As) and Contingency Management for Smoking. Completed, enrolled 110 participants across 1 site.
Detailed Summary
This study will develop: 1. Develop the computer-based brief intervention and Contingency Management (CM) components, with repeated feedback from experts, prenatal clinic staff, and participants. 2. Recruit 110 pregnant women who are actively smoking, and randomly assign recruited women to Brief Intervention, CM, combined, or control conditions. 3. Conduct follow-up evaluation at 12 weeks post-intervention to measure self-reported smoking, breath carbon monoxide (CO), and urinary cotinine levels. 4. Collect data regarding birth outcomes and evaluate the feasibility of various methods of post-partum follow-up.
Study Details
Timeline
Interventions
After completing the brief assessment battery, participants will interact with the computer for approximately 20 minutes, with structure being based on the Five A model and Motivational Interviewing.
Participants randomized by the computer into this condition will view a 20-minute music and tv videos after completing the brief assessment. The research assistant will then briefly describe the CM process, with a period for questions to assure understanding. The CM condition will involve participant-initiated submission of urine samples at prenatal visits. Clinic staff will have no responsibility for the CM component other than calling research staff when a participant wishes to submit a sample. Clinic staff will not schedule any new, additional, or unnecessary prenatal visits.
