Carers of stroke survivors face significant burdens, and increased carer strain has negative implications for both the stroke survivor and the carer. In a prospective cohort of White British and British Indian stroke survivors and their carers, we report the incidence of carer strain in each ethnic group, describe patient and carer characteristics, and identify predictors of increased carer strain. Multidimensional outcome measures were used to assess the physical and cognitive function in stroke survivors at one month and 3-6 months from stroke onset. Levels of car strain were assessed at the same time points using the Carer Strain Index and the Hospital Anxiety and Depression Scale. Statistical significance for difference in patient and carer characteristics between White British and British Indian groups was assessed. There were no differences in levels of carer strain between the two ethnic groups. These findings will inform future research, and in turn, may help to guide population-targeted interventions aimed at reducing carer strain.
