Objective: To develop a complex intervention for community pharmacy staff to promote uptake of smoking cessation services and to increase quit rates.
Design: Following the Medical Research Council framework, we used a mixed-methods approach to develop, pilot and then refine the intervention.
Methods: : We used information from qualitative studies in pharmacies, systematic literature reviews and the Capability, Opportunity, Motivation-Behaviour framework to inform design of the initial version of the intervention.
Aims: This qualitative process study, nested within a randomised controlled trial evaluating community pharmacist brief alcohol intervention delivery, aims to explore participants' engagement with the trial, so as to identify whether research participation effects may explain why the brief intervention was not found to be effective.
Method: Qualitative interviews were conducted with 24 randomly selected participants approximately one month after the end of the trial. Semi structured Interviews were conducted by telephone in which participants were asked to give a chronological account of their trial participation, leading to a discussion of possible impacts.
