For this update the review has been split into two reviews. Pharmacological interventions (with equal psychosocial support in both arms) are now covered in a separate review by Coleman 2012b. For this update, the current review now covers all other interventions. The title has been changed from 'Interventions for promoting smoking cessation during pregnancy' to 'Psychosocial interventions for supporting women to stop smoking in pregnancy'.

Search updated. We identified 16 new studies meeting the inclusion criteria.

As a result of a change in the inclusion criteria we excluded 13 studies from the previous version of the review. We also included four studies that had been previously excluded (three cluster trials and one abstract report of a trial), as well as nine studies that did not report any outcomes which could be used in meta‐analyses, and which are reported in a separate table. We combined two reports of relapse prevention (Ershoff 1995; Secker‐Walker 1995) as ‘Associated References’ to the primary papers reporting smoking cessation (Ershoff 1989; Secker‐Walker 1994), and another paper which did not report any usable outcomes (Solomon 1996) as an 'Associated reference' to the primary report (Secker‐Walker 1998).

A total of 77 randomised controlled trials, involving over 29,000 women with relevant outcome data, were included in the meta‐analysis for this review (primary outcome data for 21,948 women participating in 70 trials and secondary outcome data only for a further 7404 women participating in seven trials). A further nine trials without outcomes are included but results summarised in Table, making a total of 86 studies included in this updated review.
