Do quality-of-life domains reflecting physical function predict social participation in the chronic post-stroke phase?

Abstract

Introduction: Stroke survivors commonly present with mobility limitations, reduced social participation, and impaired quality of life. Objective: To investigate whether the physical functioning (PF) and role physical (RP) domains of quality of life predict social participation in the chronic post-stroke phase. Methods: This cross-sectional study included 23 individuals in the chronic phase after stroke. Social participation was assessed using the Participation domain of the Stroke Impact Scale, and quality of life was measured with the Medical Outcomes 36-Item Short-Form Health Survey (SF-36). The PF and RP domains were considered indirect indicators of mobility. Data were analyzed using Spearman’s correlation and simple and multiple linear regression analyses (p < 0.05). Results: Both domains were positively correlated with social participation (PF: rho = 0.652; RP: rho = 0.796; p < 0.001). In simple linear regression models, PF and RP explained 34% and 49% of the variance, respectively. In the multiple regression model, the combined variables explained 57% of the variance, with RP emerging as the strongest predictor. Conclusion: The PF and RP domains of the SF-36 are significant predictors of social participation in the chronic post-stroke phase. Greater perceived physical functioning and lower impact of physical limitations on daily roles (higher RP score) are associated with higher levels of social participation.
