Using the COM-B model to identify barriers and facilitators towards adoption of a diet associated with cognitive function (MIND diet)
Timlin D, McCormack JM, Simpson EE.. Public health nutrition, 2020-08-17
Topic: Risk, prevention and care in population studies
Objective The aim of the study was to identify components of the COM-B (capability, opportunity, motivation and behaviour) model that influences behaviour to modify dietary patterns in 40-55-year-olds living in the UK, in order to influence the risk of cognitive decline in later life. Design This is a qualitative study using the COM-B model and theoretical domains framework (TDF) to explore beliefs to adopting the Mediterranean-DASH Intervention for Neurodegenerative delay (MIND) diet. Setting Northern Ireland. Participants Twenty-five participants were recruited onto the study to take part in either a focus group or an interview. Participants were men and women aged between 40 and 55 years. Participants were recruited via email, Facebook and face to face. Results Content analysis revealed that the main perceived barriers to the adoption of the MIND diet were time, work environment, taste preference and convenience. The main perceived facilitators reported were improved health, memory, planning and organisation, and access to good quality food. Conclusions This study provides insight into the personal, social and environmental factors that participants report as barriers and facilitators to the adoption of the MIND diet among middle-aged adults living in the UK. More barriers to healthy dietary change were found than facilitators. Future interventions that increase capability, opportunity and motivation may be beneficial. The results from this study will be used to design a behaviour change intervention using the subsequent steps from the Behaviour Change Wheel.
Key findings
- Results Content analysis revealed that the main perceived barriers to the adoption of the MIND diet were time, work environment, taste preference and convenience.
- The results from this study will be used to design a behaviour change intervention using the subsequent steps from the Behaviour Change Wheel.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
