Psychosocial interventions for building resilience of informal carers of people living with stroke: a systematic review.

To identify and synthesise the evidence of interventions purported to build resilience among informal carers of stroke survivors. A systematic review of randomised controlled trials of psychosocial interventions to build resilience for carers of people post-stroke was planned. A systematic search was conducted in seven online databases from inception to March 2021. Outcomes measured were resilience and its proxy constructs including copying, adaptation, adjustment, problem-solving, self-efficacy, locus of control, competence and strength. Twelve studies were included in the review and were grouped into four intervention categories (i) Education and social support, (ii) problem-solving skills, (iii) problem-solving skills, and psychoeducation and (iv) information provision, problem-solving skills and psychoeducation. Level of evidence A exists for interventions that combine information provision, problem-solving skills and psychoeducation over the interventions that only use problem-solving skills intervention or problem-solving skills with psychoeducation strategies. All interventions apart from one reported significant within and/or between group changes in outcomes. Interventions comprising of information provision, problem-solving skills and psychoeducation appear to be beneficial to improve resilience of carers. However, because of the heterogeneity of the interventions and outcome measures reported across the twelve studies no particular intervention could be definitively supported.
