Abstract

Background Depressive symptoms are substantial among stroke survivors and their caregivers in poststroke management. Optimism and social support are known to protect against depressive symptoms. However, little is known about how optimism and social support contribute to depressive symptoms among stroke survivor-caregiver dyads. The study's purpose was to examine actor and partner effects of optimism on depressive symptoms through perceived social support among stroke survivors and caregiver dyads in the chronic stage of rehabilitation. Methods Stroke survivors and caregivers (N = 105 dyads) completed the survey at 2 years of follow-up after the first stroke. Depressive symptoms, optimism, and perceived social support were assessed using the Center for Epidemiologic Studies-Depression, the Life Orientation Test, and the Interpersonal Support Evaluation List. The Actor-Partner Interdependence Model Extended to Mediation analysis was used to test the indirect effect of optimism on depressive symptoms through perceived social support. Results Higher optimism was significantly associated with lower depressive symptoms for caregivers (direct actor effect, -0.6844; 95% confidence interval [CI], -0.9844 to -0.3844) and stroke survivors (direct partner effect, -0.4189; 95% CI, -0.0789 to -0.0889). Perceived social support availability significantly mediated the association between optimism and depressive symptoms for stroke survivors (indirect effect, -0.1957; 95% CI, -0.3923 to -0.0670). Caregiver perceived social support availability was also a significant mediator between caregivers' optimism and stroke survivors' depressive symptoms (indirect effect, 0.1658; 95% CI, 0.0559-0.3128). Conclusions Intervention improving dyad members' optimism and social support would be beneficial to improve depressive symptoms of the stroke survivors and caregivers in chronic stroke management.
