Abstract T P124: Psychometric Properties of the Chinese Version of the Stroke Specific Quality of Life Scale in Community-Dwelling Stroke Survivors
Introduction: Health-related quality of life is a significant outcome of stroke survivors’ recovery. The 49-item English version of the Stroke Specific Quality of Life Scale (SSQOL) (Williams et al., 2009) is a stroke-specific assessment of stroke survivors’ health-related quality of life in 12 domains. However there has been no Chinese version of the scale for Chinese stroke survivors in Hong Kong.
Aim: To examine the reliability and validity of the Chinese version of Stroke Specific Quality of Life Scale (SSQOL-C) in stroke survivors.
Methods: SSQOL was translated into Chinese and blind back-translated by independent bilingual baccalaureate nursing students. Content validity was reviewed by an expert panel which consisted of one nurse academic, one nurse manager, three advanced practice nurses, and two registered nurses. A cross-sectional study was conducted to validate the translated version. A convenience sample of 135 adult stroke survivors were recruited from three community centres and a stroke support group in Hong Kong. Internal consistency analysis was performed. Pearson’s correlation coefficients were calculated between SSQOL-C, SF-36, and Frenchay Activities Index (FAI) to determine the convergent validity.
Results: Content validity index of SSQOL-C was 0.99. SSQOL-C had high internal consistency with Cronbach’s alpha of 0.94 for the total scale, and between 0.65 and 0.90 for the 12 domains. The total SSQOL-C scores showed significant positive correlations with SF-36 physical health (r=0.58, p<0.01) and mental health (r=0.54, p<0.01) component scores, and FAI score (r=0.59, p<0.01). SSQOL-C physical subtotal scores showed significant positive correlations with SF-36 physical health (r=0.55, p<0.01) and mental health (r=0.43, p<0.01) component scores, and FAI score (r=0.54, p<0.01). SSQOL-C psychosocial subtotal scores showed significant positive correlations with SF-36 physical health (r=0.52, p<0.01) and mental health (r=0.56, p<0.01) component scores, and FAI score (r=0.56, p<0.01).
Conclusion: The results showed SSQOL-C had good content and convergent validity, and reliability in Chinese stroke survivors. Further evaluation of factor structure of SSQOL-C will be conducted to determine its validity.
