Trial Outcomes & Findings for Native-Changing High-risk Alcohol Use and Increasing Contraception Effectiveness Study (NCT NCT03930342)

NCT ID: NCT03930342

Last Updated: 2025-04-17

Results Overview

Our primary outcome is measurement of change in risk of alcohol exposed pregnancy (AEP). Being at risk for an AEP is defined as engaging in heavy/binge drinking and ineffective contraception use in the 3 months prior to the final data collection session after exposure to the intervention. Count reflects number of participants who remained at risk for an AEP.

Native CHOICES Intervention
Native-CHOICES will comprise usual care plus 2 Motivational Interviewing (MI) sessions delivered over 4 weeks; a contraception counseling session at a local clinic; and 3 months of electronic messaging to boost the effects of MI and counseling by increasing perceptions of social connection and social support for behavior change. Contraception counseling will be completed within 2 weeks after the second MI session, so the maximum duration of MI and counseling for each participant will be 6 weeks. Electronic messaging will include positive motivational content consistent with alcohol and contraception use goals set in the MI sessions. Native-CHOICES: Native CHOICES is a behavioral intervention for prevention of prenatal alcohol exposure in women at high risk for alcohol-exposed pregnancies. The intervention uses motivational interviewing and cognitive-behavioral strategies, and targets adoption of effective contraception and reduction of alcohol use.
Wait-list Control Group
The control condition will comprise usual care for the 6-month study period, with a wait-list design that offers women the Native- CHOICES program after they have completed the 6-month data collection.
