Background: Stroke is highly debilitating and requires long-term care. Informal caregivers of stroke survivors play important roles in stroke rehabilitation. Caring for stroke survivors can negatively affect the caregivers' well-being and may adversely impact on their caregiving quality and subsequently on stroke survivors' well-being. There seems to be a dearth of research on the relationships between caregivers' and stroke survivors' well-being.; Aims and Objectives: This study was designed to determine the relationships among informal caregivers' burden and quality of life (QOL) and stroke survivors' QOL and community reintegration.; Methods: This ethically certified cross-sectional survey involved 82 stroke survivors (mean age = 60.48 ± 11.13 years) and their 82 primary caregivers (mean age = 36.13 ± 13.69 years) consecutively recruited from seven conveniently sampled tertiary hospitals in Nigeria. Caregivers Strain Index, Igbo-culture adapted Maleka Stroke Community Reintegration Measure and Short-Form 36-item Health Survey questionnaires were used to assess the caregivers' burden, survivors' community reintegration and QOL (of survivors and caregivers), respectively. Data were analysed using descriptive statistics, Spearman rank, Mann-Whitney U and Kruskal-Wallis tests at alpha level of 0.05.; Results: The mean stroke survivors' community reintegration and QOL were 34.05 ± 21.54% and 34.93 ± 16 ± 49%, respectively. The mean caregivers' QOL and burden scores were 74.49 ± 12.61% and 9.13 ± 3.18, respectively. About 80.5% of the caregivers experienced significant burden. Stroke survivors' QOL and community reintegration, and caregivers' QOL and burden significantly correlated with one another (p < 0.05). Poststroke duration, survivor-caregiver cohabitation duration, survivors' community-dwelling duration and daily care-giving hours significantly correlated with each of stroke survivors' community reintegration and QOL, and caregivers' burden and QOL (p < 0.05).; Conclusions: Stroke survivors' community reintegration and QOL were poor while caregivers' had moderate QOL and high prevalence of significant burden. Significant correlations exist between caregivers' well-being and stroke survivors' QOL and community reintegration. Interventions targeted at reducing caregivers' burden may help improve both caregivers and survivors' well-being.
