RESUMEN
Smoking during pregnancy is a global health problem which has devastating health implications. Behavioural support is an important part of smoking cessation support for pregnant women. Research has identified barriers and facilitators (B&Fs) and effective behaviour change techniques (BCTs) to aid women's quit attempts. However, the extent to which and how these BCTs are used in practice is unclear. The research aimed to establish experts' views on how behavioural support can be optimised and techniques operationalised in clinical practice, by identifying ways to address known B&Fs for smoking cessation in pregnancy. A focus group discussion took place with six experts, which highlighted how BCTs can be used in practice to support women in their quit attempts. A thematic analysis was conducted to elicit overarching themes. Five themes were found: involving the family, empowering women, using incentives to boost motivation, using practical techniques to help women with their quit attempts and managing expectations about nicotine replacement therapy. Empowering women to make their own decisions and encouraging small positive changes in smoking habits, using visual aids (e.g., growth charts) to inform women of the harms of smoking to the baby and treating families holistically were deemed important.
