Abstract
PURPOSE: This study aims to examine the effect of online individual motivational interviewing based on the transtheoretical model on pregnant women's smoking cessation behaviour. MATERIAL AND METHOD: Sixty-two pregnant women who did not complete the 16th gestational week and who smoked were randomly assigned to intervention (n = 31) and control (n = 31) groups. While the intervention group was administered model-based motivational individual counselling interventions, the control group was administered no interventions. FINDINGS: The results showed that 58.1% of the pregnant women in the intervention group and 22.6% of the pregnant women in the control group ceased smoking. CONCLUSION: Online motivational interviewing based on the transtheoretical model was found to be effective in pregnant women's smoking cessation.
