Despite the growing international innovations for visual arts interventions in dementia care, limited attention has been paid to their theoretical basis. In response, this paper explores how and why visual art interventions in dementia care influence changes in outcomes. The theory building process consists of a realist review of primary research on visual art programmes. This aims to uncover what works, for whom, how, why and in what circumstances. We undertook a qualitative exploration of stakeholder perspectives of art programmes, and then synthesised these two pieces of work alongside broader theory to produce a conceptual framework for intervention development, further research and practice. This suggests effective programmes are realised through essential attributes of two key conditions (provocative and stimulating aesthetic experience; dynamic and responsive artistic practice). These conditions are important for cognitive, social and individual responses, leading to benefits for people with early to more advanced dementia. This work represents a starting point at identifying theories of change for arts interventions, and for further research to critically examine, refine and strengthen the evidence base for the arts in dementia care. Understanding the theoretical basis of interventions is important for service development, evaluation and implementation.

This study responds to a gap in the literature relating to the resilience of people living with dementia in care homes. We applied an ecopsychosocial framework of resilience, theorising that sources of resilience may be personal, social and structural. Visual arts enrichment activities were examined to see how they might provide opportunities for resilience. The data used for this study were qualitative and originated from people with dementia aged between 70 and 99 years old (N = 48) living in four care homes in North East England, United Kingdom and staff/carers/family members (N = 37). The results showed that visual arts enrichment activities supported the resilience of those with dementia through creative expression, increased communication, improved self-esteem, and influenced relationships with carers and family members. It is concluded that even those with advanced dementia are capable of demonstrating resilience which can be supported by, and explored through, visual arts enrichment activities.

Understanding the interplay between social capital, cultural capital, and reminiscence has implications for programmers and policy makers trying to engage less culturally engaged participants in the arts. Developing bonding, bridging, and linking social capital and cultural capital through engagement with the arts may have implications for health, particularly among this demographic.

BackgroundArts-based activities are being increasingly suggested as a valuable activity for people living with dementia in terms of countering the negative aspects of their condition. The potential for such programmes to improve a broad range of psychosocial outcomes is suggested in some studies. However, there is largely an absence of rigorous methodology to demonstrate the benefits, and research results are mixed. Practice variability in terms of the content, contexts and implementation of such interventions raises challenges in terms of identifying an optimal arts programme model that could be adopted by other service providers. Understanding how interventions may have the best chance at broad implementation success and uptake is limited.Methods/DesignA realist review will be undertaken. This aims to understand how visual arts interventions influence outcomes in people living with dementia. The review will explore how the context, that is the circumstances which enable or constrain, affect outcomes through the activation of mechanisms. An early scoping search and a stakeholder survey formulated the preliminary programme theory. A systematic literature search across a broad range of disciplines (arts, humanities, social sciences, health) will be undertaken to identify journal articles and grey literature. Data will be extracted in relation to the programme theory, contextual factors, mechanisms and outcomes and their configurations, background information about the study design and participant characteristics, detail about the quantity (‘dose’) of an intervention, theoretical perspectives proposed by the authors of the paper and further theorising by the reviewer. Thematic connections/patterns will be sought across the extracted data, identifying patterns amongst contextual factors, the mechanisms they trigger and the associated outcomes.DiscussionAlong with stakeholder engagement and validation, this review will help inform the development of an optimal, replicable arts intervention for people with dementia as part of our broader research programme, titled ‘Dementia and Imagination’ (funded by the Arts and Humanities Research Council). Forthcoming work under this programme of research will test this theoretically informed intervention in three different geographical areas of the UK. The production of freely available practice guidance is a key aspect of dissemination.Trial registrationPROSPERO registration number CRD42014008702.
