Touchscreen interventions and the wellbeing of people with dementia and caregivers: a systematic review

Background: Dementia can have significant detrimental impacts on the wellbeing of those with the disease and their carers. A range of computer-based interventions, including touchscreen-based interventions have been researched for use with this population in the hope that they might improve psychological wellbeing. This article reviews touchscreen-based interventions designed to be used by people with dementia, with a specific focus in assessing their impact on wellbeing. Method: The data bases, PsycInfo, ASSIA, Medline, CINAHL and Cochrane were searched for touchscreen-based interventions designed to be used by people with dementia with reported psychological wellbeing outcomes. Methodological quality was assessed using Pluye et al.’s (2011) Mixed Methods Appraisal Tool (MMAT) checklist. Results: Sixteen papers were eligible. They covered fourteen methodologically diverse interventions. Interventions were reported to be beneficial in relation to mental health, social interaction and sense of mastery. Touchscreen interventions also reportedly benefit informal carers in relation to their perceived burden and the quality of their relationships with the people they care for. Key aspects included the user interface, provision of support, learning style, tailored content, appropriate challenge, ergonomics and users’ dementia progression. Conclusions: Whilst much of the existing research is relatively small-scale, the findings tentatively suggest that touchscreen based interventions can improve the psychological wellbeing of people with dementia, and possibilities for more rigorous future research are suggested
