Abstract

BackgroundAsthma control in adolescents is low with half of the young people in a London study identified as having suboptimal control when measured using the Asthma Control Test. Control of asthma symptoms can be improved by addressing barriers to good self-management, such as poor understanding of asthma and adherence to medication. The aim of this study was therefore to develop the My Asthma in School (MAIS) intervention for the improvement of asthma control and self-management in adolescents and to test its initial feasibility. The intervention intended to combine a strong focus on theory with a design specifically aimed to engage adolescents.MethodsThe intervention development was based on previous qualitative and quantitative findings, and on guidelines from the Medical Research Council for the development of complex interventions. The COM-B (Capability, Opportunity, Motivation–Behaviour) model was applied to inform the design of intervention elements. Behavioural targets were identified from existing barriers to good asthma self-management and were then used to guide the development of engaging intervention elements, which were described using the Behavioural Change Technique (BCT) Taxonomy version 1. Adolescents were involved throughout this process. The MAIS intervention was tested in a feasibility phase in London secondary schools with adolescents aged between 11 and 13.ResultsThe complex school-based MAIS intervention comprised a first school visit from a theatre group, who conducted a workshop with all year 7–8 students and addressed peer understanding and attitudes to asthma. The second visit included four self-management workshops for adolescents with asthma, including games, short-films and role play activities. Forty different types of techniques to change behaviour were applied, totalling 163 instances of BCT use across intervention elements, addressing all areas of capability, opportunity and motivation. In this initial feasibility study, 1814 adolescents with and without asthma from nine schools received the theatre intervention visit; 23 adolescents with asthma from one of the schools attended the workshop visit. The intervention was found acceptable and engaging, and 91.4% of participants agreed that the workshops changed how they think or feel about asthma.ConclusionThis study demonstrates development and initial feasibility of a complex theory-based intervention, and how it can combine engaging media and interactive elements, to achieve a multi-directional approach to behavioural change. However more work is needed to assess the feasibility of trial processes, including recruitment and delivery format of the workshops.

Highlights

  • Asthma control in adolescents is low with half of the young people in a London study identified as having suboptimal control when measured using the Asthma Control Test

  • This study demonstrates development and initial feasibility of a complex theory-based intervention, and how it can combine engaging media and interactive elements, to achieve a multi-directional approach to behavioural change

  • There is evidence in the UK that almost half (49.6%) of young people has suboptimal asthma control when assessed by the Asthma Control Test (ACT) [2]

Summary

Introduction

Asthma control in adolescents is low with half of the young people in a London study identified as having suboptimal control when measured using the Asthma Control Test. Control of asthma symptoms can be improved by addressing barriers to good self-management, such as poor understanding of asthma and adherence to medication. The aim of this study was to develop the My Asthma in School (MAIS) intervention for the improvement of asthma control and self-management in adolescents and to test its initial feasibility. For the majority of asthma patients, medications have the potential to control symptoms well [1]. Results from the school-based asthma project (SAP) [2] reported a lack of understanding of symptom severity. Of the young people identified with suboptimal asthma control, 42.4% judged their asthma to be either ‘well’ or ‘completely controlled’ [2]
