Abstract
Background
Cognitive training (CT) may be beneficial in mild cognitive impairment (MCI) and early dementia. However, few studies have qualitatively evaluated CT programmes in dementia. The aim of this analysis was to explore the benefits and barriers to a home-based computerised CT programme for healthy older adults, and people living with MCI or dementia.
Methods
This was a nested qualitative study within a larger feasibility randomised trial of CT. Participants underwent semi-structured interviews after 12 weeks of CT. Where possible, participants were interviewed with their carers. The interview schedule and analysis were underpinned by the health belief model. Interviews were audio-recorded, transcribed, open-coded, and categorised into themes. The analytical framework was developed, and themes were condensed under four major categories: benefits and efficacy, barriers, threat, and behaviour.
Results
37 participants underwent interviews (10 healthy older adults, 4 MCI, 5 dementia, 9 patient-carer dyads [2 MCI, 7 dementia]). CT was feasible and acceptable to participants. Benefits included: enjoyment, improved awareness, benchmarking cognitive function, reassurance of abilities, and giving back control. Barriers were more prevalent amongst those with dementia: problems with technology, frustration, conflict between patients and carers, apathy and lack of insight, anxiety or low mood, and lack of portability. Perceived risk susceptibility of dementia varied between participants. Healthy older adults and MCI perceived the severity of dementia risk as high, which was only partially mitigated by CT. Participants living with dementia valued a more individualised approach to training, accounting for baseline characteristics. For people living with dementia, maintenance was as valued as improvement of cognitive function.
Conclusions
CT was a feasible intervention for healthy older adults, and people living with dementia and MCI. Benefits were present, but the identified barriers need to be addressed for CT to be implemented successfully.
