Resilience in the first year of surviving a stroke in Nigeria.

Objectives: There is a knowledge gap on resilience and its impact on mental health of Africans who survive a stroke. We describe the trajectory of psychological resilience and its association with depression and quality of life (QoL) across the first poststroke year in Nigeria.

Method: Prospective observational study of 150 survivors of a first ever stroke. Resilience was ascertained at 3 time-points prospectively over 12 months using the 25-items Resilience Scale (RS). Depression and QoL were also assessed at baseline and follow-up, respectively using the centre for epidemiologic studies depression scale (CES-D 10) and health related quality of life in stroke patients (HRQOLISP-26). Associations were investigated using regression models and presented as adjusted odds ratios (OR) and Wald test coefficients within 95% confidence intervals (CI).

Results: Resilience improved across time points of measurement (p < 0.001). In multivariate logistic regression analyses adjusted for the effect of age, education, alcohol use, and hypertension, higher resilience was associated with male sex (OR = 5.3, 95% CI= 1.7, 17.2), younger age (OR = 4.8, 95% CI = 1.5,15.7), and baseline hypertension (OR= 0.2, 95% CI ≤ 0.1,0.8). In similarly adjusted mixed effect linear regression analyses, higher resilience was associated with improvement in depression (months 12= -4.2, 95% CI= -5.6, -2.8) and quality of life (months twelve = 5.2, 95% CI = 2.2, 8.2) overtime.

Conclusion: Resilience, which was associated with better mental health and wellbeing of stroke survivors, was less likely with hypertension. Results suggest an important role for control of vascular risk factors as part of resilience interventions to promote poststroke recovery.
