Results
The results of the exploratory factor analysis section with the main component method and oblique rotation the 10 factors of self-care and upper extremity function (variance=46.09%), social roles (variance=60.29%) Language (variance =68.60%), vision (variance=74.47%), thinking (variance=79.56%), energy (variance =84.25%), personality (variance=87%), mood (variance =90.14%), mobility (variance=92.42%), family roles (variance =93.88%).
Simultaneous validity also showed correlation (r = 0.73) and statistically significant (P ≤0.05). The reliability of the questionnaire was also reported by intra-class correlation coefficient and Cronbach's alpha method as 0.99 and 0.97, respectively.
