Risk, worry and motivation: How is public knowledge of dementia shaped?

Abstract

Background and Objectives Due to the concern over global rising rates of dementia, increased emphasis has been placed on understanding and moulding the public’s knowledge and awareness of the condition. There has been limited previous research into predictors of dementia knowledge; overall knowledge amongst the public is low, and it has been widely agreed that more needs to be done to raise awareness of this condition. This study seeks to solidify understanding of public dementia knowledge and introduces dementia worry, motivation to seek information and risk perception as novel concomitants of this knowledge. Research Design and Methods A convenience sample of 311 UK adults completed a survey on dementia knowledge including Alzheimer’s disease-specific questions, worry about developing dementia, motivation to seek information and perceived personal risk of getting the disease. Surveys were completed face-to-face and included both closed and open-ended questions. Results Overall dementia knowledge scores were low, achieving an average of 33% of the total possible score, with 88% of the sample scoring below 50%. Bivariate correlations were performed between dementia knowledge and key variables, revealing significant positive relationships with risk perception ( r = 0.179, p = .002), worry ( r = 0.140, p = .016) and motivation to seek information ( r = 0.139, p = .016). When knowledge was dichotomised into high and low, worry about ( p = .28) and perceived risk ( p = .19) of dementia was significantly lower for people with low knowledge scores than for people with higher dementia knowledge scores. Motivation to seek information was not significantly different between the high and low knowledge groups ( p = .071). Discussion and Implications Despite the relatively low knowledge scores, findings show a positive relationship between modifiable factors and dementia knowledge, suggesting areas to consider for both further research and publication campaigns. Further implications and limitations of this study are discussed.

“I guess you can interpret it in a number of ways like kind of a milder or the mildest form of dementia?”: Multi-stakeholder perceptions of cognitive impairment

“…This highlights the need for further research and clear dissemination of research results surrounding lifestyle factors, but also suggests that specialists possess knowledge which should be shared with the wider patient and public population to ensure people are able to make informed lifestyle choices. A positive correlation between overall knowledge and modifiable risk factors has been identified in a survey of dementia knowledge (Ashworth et al, 2021), suggesting that increasing awareness of cognitive impairment may enhance knowledge of modifiable risk factors. The World Health Organization has recently released guidelines around reducing the risk of cognitive impairment and dementia which focus on lifestyle interventions (World Health Organization, 2019).…”

Is the Invisibility of Dementia a Super-Power or a Curse? A Reflection on the SUNshiners’ Questionnaire into the Public Understanding of Dementia as an Invisible Disability: A User-Led Research Project

“…The majority of people recognised that dementia is something that could happen at any age, although it is more likely to be seen in older adults. It is positive to see a general increase in the public's self-rated knowledge of dementia and the recognition that dementia can be early-onset [55].…”

Personal Health Planning in Adult-Child Former Caregivers of Parents Living With Dementia

“…For example, an increasing prevalence of Alzheimer’s disease and related dementias has been shown to spur adults’ heightened attention to dementia-related health changes in their cognition or functioning. 22,23 Caring for a PLWD has been associated with increased concerns about the likelihood of one’s own development of cognitive problems 24,25 and, consequently, cognitive symptom monitoring. 26,27 Few studies have examined other ways that caregiving for a PLWD can influence former caregivers’ personal health planning.…”
