Abstract:

Objective To test the reliability and validity of Work-ability Support Scale (WSS) in stroke patients.
Methods WSS was translated into Chinese with the standard translation-retroversion. From December, 2018 to March, 2019, 193 middle-aged and young stroke patients from two community health service centers in Zhengzhou were conveniently selected, and investigated with Chinese WSS by two nurses. The data were analyzed with item analysis, content validity, exploratory factor analysis, internal consistency reliability and inter-rater reliability.
Results The content validity was 0.94 in WSS A and 0.90 in WSS B. Three factors were extracted from 16 items in WSS A, with cumulative variance contribution of 67.747%; while three factors were extracted from 12 items in WSS B, with cumulative variance contribution of 56.056%. Cronbach's α was 0.933 and 0.778 in WSS A and WSS B, respectively. The kappa coefficient was above 0.6 between two raters in every item, except items B8 and B10.
Conclusion Chinese WSS is satisfactory in validity and reliability for using in young and middle-aged stroke patients during their return to work.
