act for people with dementia experiencing psychological distress

Conditions: Acceptance and Commitment Therapy; Dementia

Summary: introduction: people with dementia have a high prevalence of psychological distress but are under-served with evidence-based psychological interventions. to promote choice and improve clinical outcomes, there is a necessity to test different psychological intervention options for this population. purpose: to investigate the effectiveness and acceptability of acceptance and commitment therapy (act) for people with dementia, considering carer-supported, remote delivery and necessary therapy adaptations. methods: a hermeneutic single case efficacy design (hsced) series was used to analyse therapy process and change for three clients with dementia and psychological distress. quantitative and qualitative data was collated ('rich case records') and analysed by three independent psychotherapy experts ('judges') who determined the outcome for each client. results: over the course of therapy, it was concluded that one client with dementia made positive changes, specifically reliable reductions in psychological distress, which were largely attributable to acceptance and commitment therapy (act). two clients remained unchanged. discussion/conclusion: where change was achieved, the act-specific processes of values, committed action and acceptance, in combination with non-specific therapy factors including a strong client-carer relationship, existing client interests and individualised therapy adaptations, were facilitative of change. hence, act may be feasible and effective by helping carers to better meet the needs of their loved ones with dementia. future research to optimise act delivery in this population may be beneficial. furthermore, the assessment of carer factors (e.g., their psychological flexibility, the client-carer relationship) may strengthen the evidence-base for systemic act-use.
