Abstract

Objective: To explore what motivates individuals to change their behaviour to reduce their risk of dementia.
Methods: We conducted secondary qualitative analysis of a UK-based online survey on motivation to change lifestyle and health behaviour for dementia risk reduction. Participants were recruited through social media, the Join Dementia Research network and the National Institute for Health Research Portfolio. Free-text comments from people aged ≥50 years were analysed by two researchers independently using inductive content analysis. Inter-rater agreement was measured through Cohen’s Kappa coefficient.
Results: Of the 3,948 participants completing the survey, 653 provided free text comments that were included in the analysis (Mean age=64.1; SD=8.3 years). The majority of the sample were women (n=459; 70.3%), Caucasian (n=625; 95.7%) and married/in partnership (n=459; 70.3%). Three overarching themes were identified: (1) motivators to changing lifestyle; (2) barriers for lifestyle change; and, (3) quality of the information received. The inter-rater reliability of the coding was high (k=0.7). Having a family history of dementia or feeling like they had a healthy lifestyle already were motivating factors for behaviour change. Having competing health priorities other than dementia and caring for someone acted as de-motivators as they reduced the time available to dedicate to one’s own health. Evidence-based information around dementia prevention was a motivator, but commonly the information was not trusted.
Discussion: Aligned with the World Health Organisation (WHO) mandate on dementia prevention, community health campaigns targeting population awareness around behaviour change and dementia risk factor reduction are urgently needed. To be successful, such campaigns will need to be accompanied by individual approaches that can overcome age-related barriers and individual differences in motivation levels, personal barriers and trust in the information received.
