Benefits of Incentives for Breastfeeding and Smoking cessation: A platform study for a trial (BIBS)

Summary

The aim of this research is to try and find out which incentives (financial or non-financial), if any, are most likely to help women to stop smoking in pregnancy (and not restart) and to breastfeed their babies until 6 months, to benefit the health of both mothers and babies.   There are three stages to BIBS:

Stage 1. We will synthesize the evidence for incentives delivered to women, families and NHS or non NHS providers and their associated theories of behaviour change, using focused research questions to inform the design of a trial. This will produce: i) evidence synthesis reports ii) a taxonomy of incentive characteristics, behaviour change theory, mechanisms of action and the barriers/facilitators to stopping smoking in pregnancy and breastfeeding iii) a short list of promising incentives.

Stage 2. For the incentive short-list we will investigate recipient, provider and public acceptability and any unintended effects. Mixed method data will refine the incentive characteristics, timing, quantity, delivery processes, recipient monitoring, organisational, environmental and contextual factors that are likely to increase effectiveness.

Stage 3. A Discrete Choice Experiment will refine the most promising intervention(s) to trial. The DCE will identify the relative probabilities of behaviour change for different types and level of incentive intervention and inform effect sizes. If probabilities vary across individuals with different characteristics, and affect outcomes, then a range of incentives may be more effective than a ‘one-size-fits-all’ approach. Combining all aspects of this study will enable us to define a trial intervention, recruitment and delivery strategies, provide a sample size calculation, model effect sizes and define outcome measurements. This will inform the design of a trial.
