SolCos model-based individual reminiscence for older adults with mild to moderate dementia in nursing homes: a randomized controlled intervention study

Aim: To investigate the effect of a standardized individualized intervention based on the SolCos transformational reminiscence model on depressive symptoms (primary outcome), cognition and behaviour (secondary outcomes) for older people with mild to moderate dementia, performed by trained nursing home volunteers as facilitators. Background: Because of limited pharmacological treatment options for older adults with dementia relevant physical, sensory, psychological or social interventions offer alternative opportunities. Method: Randomized controlled trial (ISRCTN74355073) was set up in two nursing homes with 29 and 31 residents in the intervention and the control groups respectively. Eighteen nursing home volunteers were trained to perform the reminiscence therapy. Various assessment scales were measured pre- and post-sessions. Results: Linear regression analysis showed an impact on depressive symptoms. However, no impact was identified on cognition and behaviour. Facilitators experienced the sessions as useful and pleasant, and study participants were, in general, attentive, open and collaborative. Discussion: Study results showed that organizing standardized individual reminiscence therapy with nursing home volunteers was feasible and study participants' attention and participation were overall good. Further study initiatives to explore the potential of individual reminiscence therapy within a person-centred framework are recommended in order to improve care in nursing homes.
