Support items, used to understand the level of assistance needed in a domain or the degree to which an individual can perform tasks independently, are rated from 0 to 4, where higher scores indicate greater independence and less need for support. Satisfaction items, which assess how satisfied an individual is with various aspects of their life, are rated on a 0-3 scale, with higher scores reflecting greater satisfaction in that domain.
