Title: Evaluation of a Tailored Text Message Intervention for Pregnant Smokers (MiQuit): a Pilot Trial
Brief Summary: The overall aim of the study is to estimate the likely impact of the MiQuit text message based smoking cessation service for pregnant smokers and to establish robust estimates for the key factors which would be required in order to design a larger definitive trial of this intervention(MiQuit).

These key factors include: the range of recruitment rates in different centres; quit rates amongst participants; feasibility of assessing smoking status of participants in later pregnancy; and the likely effect of MiQuit when women are offered this in National Health Service (NHS) settings.
