Smartphone App and Peer Support to Help Pregnant Women Quit Smoking

What this Trial Is About

Researchers are evaluating a smartphone-based intervention designed to help pregnant smokers quit smoking by using an app combined with peer support. The project aims to develop, implement, and test the feasibility and effectiveness of the SFT 2.0 app, which uses deep tailoring, reinforcement learning, and motivational interviewing counseling techniques. The study also seeks to build mobile health research capacity in Romania and improve support for smoking cessation during pregnancy and postpartum periods. The trial has three study groups one group uses the SFT 2.0 app and receives a fixed number of four counseling video sessions during pregnancy up to one month postpartum another group uses an adaptive version of the app with as-needed counseling sessions ranging from one to ten during the same period and a control group receives low-dose counseling with one prenatal and one postnatal session. Both experimental groups involve use of the app by pregnant smokers and their nominated support persons. Participants will be involved for a period covering pregnancy through postpartum, with evaluations of smoking cessation and abstinence conducted at three and six months after birth. Researchers will assess outcomes such as reach, adoption, implementation, and user engagement one month after birth. The trial is randomized and double-blinded, with assessments including video counseling and app usage data to measure effectiveness and feasibility of the intervention.
