The specific aims are: a) to propose a method to select ICF categories to be entered in a regression model when a large amount of ICF-based data have to be handled and b) to identify candidate ICF categories for a Generic ICF Core Set by examining the explanatory power of ICF categories in relation to item one of the SF-36 using regression modeling.
