The aim of the PhD is to develop a theory-based intervention targeting adherence to inhaled corticosteroids (ICS) in adults with asthma and to evaluate its acceptability and feasibility in a primary care NHS setting. 

Using the Medical Research Council (MRC) framework for the development of complex interventions the PhD addresses the following objectives:

  1. To investigate the theoretical background to non-adherence through relevant literature reviews.
  2. To identify needs which are currently unmet in asthma review consultations from the perspective of the healthcare provider in an observational service-evaluation study. 
  3. To explore experiences of asthma, ICS and health care services from the patient perspective and to develop the intervention using a person-based approach in a focus group study.
  4. To explore the acceptability and efficacy of the intervention’s core component in increasing motivation to adhere to ICS.
  5. To investigate the feasibility and acceptability of the theory-based adherence intervention when delivered by pharmacists to adults with asthma in general practice.
