Stroke survivors are prone to functional impairments and reduced quality of life (QoL). This study examined the mediating role of social support and hope in the relationships between functional impairment, emotional distress, and QoL.
A total of 188 stroke survivors in Hong Kong completed assessments on functional impairment, social support, and hope at baseline, with follow-up measurements of emotional distress at 2 months and QoL at 8 months. Structural equation modeling with bootstrapping was used to analyze the direct and indirect effects of functional impairment on emotional distress and QoL the mediating factors of social support and hope.
The partial cascading model provided an adequate fit to the data. Functional impairment had significant negative direct effects on hope and physical QoL and social support had significant positive direct effects on hope and physical QoL. Social support had a significant positive indirect effect on physical QoL hope and perceived stress and on psychosocial QoL hope and depression. Functional impairment and hope had a significant negative interaction effect on perceived stress.
The findings support a mediating role for hope in the relationship between social support and QoL in stroke survivors. The protective effect of hope on perceived stress was stronger among patients with greater functional impairment.
中风幸存者容易出现功能障碍和生活质量（QoL）下降。本研究探讨了社会支持和希望在功能障碍、情绪困扰与生活质量之间关系中的中介作用。
香港的188名中风幸存者在基线时完成了功能障碍、社会支持和希望的评估，并在2个月时进行情绪困扰的随访测量，在8个月时进行生活质量的随访测量。采用带有自抽样法的结构方程模型分析功能障碍对情绪困扰和生活质量的直接和间接影响，以及社会支持和希望的中介因素。
部分级联模型对数据拟合良好。功能障碍对希望和身体生活质量有显著的负向直接影响，社会支持对希望和身体生活质量有显著的正向直接影响。社会支持对身体生活质量（通过希望和感知压力）以及心理社会生活质量（通过希望和抑郁）有显著的正向间接影响。功能障碍和希望对感知压力有显著的负向交互作用。
研究结果支持希望在中风幸存者社会支持与生活质量关系中的中介作用。在功能障碍较大的患者中，希望对感知压力的保护作用更强。
