The effect of online motivational interviewing on pregnant women's smoking cessation behaviour: A randomized controlled trial.

Smoking cessation was based on pregnant women's self-report, not biochemical verification. The analysed sample was small (62 pregnant women) and came from family health centres in a Turkish region, so results may not apply elsewhere. The researcher delivered the intervention and was not blinded; only the statistician and reporting were blinded. The paper reports different intervention cessation rates: 54.8% in the results text and 58.1% in the table and discussion. Final follow-up tables show different available sample sizes, such as 13 intervention and 24 control participants for nicotine addiction scores, so not all outcomes were available for all 62. The control group received smoking cessation training after the study, so the comparison is with delayed training rather than usual care alone. Participants had to be literate and able to use a smartphone or computer, so the trial says less about pregnant smokers without that access.

Do not read the higher cessation rate as biochemical proof of quitting or as evidence that online motivational interviewing works for all pregnant smokers. The programme combined online delivery, motivational interviewing, transtheoretical stages, and repeated sessions, so the trial cannot separate which component mattered. Smoking status was self-reported, the sample was small, and the paper reports both 54.8% and 58.1% cessation in the intervention group.
