About this trial
This randomized controlled trial aims to determine the effect of motivational interviewing-based, digital game-supported counseling on postpartum smoking relapse among pregnant women who quit smoking spontaneously during pregnancy. Women who smoked at least one cigarette per day before pregnancy and quit smoking during pregnancy will be included. Participants will be randomly assigned to two groups: in the intervention group, online motivational interviewing sessions will be delivered once each during the third and fourth prenatal follow-ups by the researcher, and a digital game assignment will be provided after each session; the control group will receive routine health counseling delivered during prenatal follow-ups. The primary outcome measure is the rate of smoking relapse at three months postpartum. Secondary outcome measures include the postpartum slip rate, craving to smoke, and motivation to remain abstinent.

Treatments tested in this trial
Motivational Interviewing and Digital Game-Supported Counseling
BehavioralCollaborative, autonomy-supportive counseling delivered in two structured sessions using motivational interviewing techniques, scheduled during the 3rd and 4th routine antenatal visits. The counseling focuses on sustaining abstinence, coping with cues, relapse prevention, and managing partner/household exposure. Each session follows a manualized protocol, with a session checklist completed at every visit. After each session, participants are assigned a digital game-based task designed to reinforce key counseling themes and support behavior maintenance.
Routine Antenatal Care
BehavioralRoutine antenatal care is provided at the study hospital according to the Ministry of Health's pregnancy follow-up program, which includes visits at ≤14 weeks, 18-24 weeks, 28-32 weeks, and 36-38 weeks of gestation.
