Capability, Opportunity, Motivation leads to adherence behaviour in people with asthma: protocol for a cross-sectional study.
ABSTRACT
Background:
Asthma is a common lung condition that cannot be cured, but it can usually be effectively managed using available treatments [1]. Despite this, it is widely acknowledged that 70% of patients do not adhere to their asthma treatment [2]. Personalizing treatment by providing the most appropriate interventions based on the patient's psychological/behavioral needs, produces successful behaviour change [3]. However, health care providers have limited available resources to deliver a patient-centred approach to their psychological/behavioural needs, resulting in a current one-size-fits-all strategy due to the non-feasible nature of existing surveys. The solution would be to provide health care professionals with a clinically feasible questionnaire that identifies the patients personal psychological/behavioural factors to adherence.
Objective:
This study aims to assess a behavioural change questionnaire’s capacity to detect patients perceived psychological and behavioural barriers to adherence in asthma patients. It also aims to explore the key psychological and behavioural barriers indicated by capability, opportunity and motivation and adherence to treatment in patients with confirmed asthma with heterogenous severity.
Methods:
In a single visit, participants visiting Portsmouth Hospital asthma clinic with a diagnosis of asthma will be asked to complete a 20-minute questionnaire on an iPad, about their psychological and behavioural barriers following the theoretical domains framework and capability, opportunity, and motivation model. Participants routinely collected data, including demographics, asthma characteristics, asthma control, asthma quality of life, medication regime, will be recorded onto an electronic data capture form.
Results:
The study is already underway, and it is anticipated that the results will be available in 2022.
Conclusions:
The COM-B asthma (study to investigate how capability, opportunity and motivation leads to the adherence behaviour of asthma medication) study will ascertain the prevalence of non-optimal adherence regarding specific behavioural and psychological barriers, assess the content validity of a behavioural change questionnaire in identifying behavioural sources, compare the responses between capability, opportunity and motivation sources with levels of adherence measured by; medicines possession ratio and advanced measures of adherence (including FeNO suppression), as well as compare asthma variables (e.g., type of asthma, asthma severity, level of asthma control and number of comorbidities) and scores of the digital readiness. Future work will involve the clarification and classification of these sources of behaviour with the most appropriate intervention function and policy categories, into pathways for health care professionals to provide the most effective behavioural change care.
