Smoking in pregnancy: the role of the transtheoretical model and the mother's attachment to the fetus

This study investigated whether pregnant smokers demonstrated cognitive and behavioural patterns hypothesised to underpin the different stages of change (SOC) and whether fetal attachment varied according to this process. A cross-sectional design with women categorised by SOC was used and the sample was recruited from hospital maternity services in the U. K at their booking clinics with a mean gestation of 14 weeks. Experiential and behavioural processes together with self-efficacy and attachment to the fetus were measured in 637 women. As predicted by the transthoretical model experiential processes were used mostly by women in contemplation and preparation; behavioural processes mostly by women in preparation and action. However, self-efficacy remained constant between precontemplation, contemplation and preparation, but women in action showed significantly higher levels. Women in preparation were significantly more attached to the fetus than women in precontemplation and never smokers. The relevance of the transtheoretical model with pregnant smokers is supported. Foetal attachment may be differentially associated with different SOC in smoking cessation and yield potential for the development of new interventions
