techniques we perform to quantify a patient's impairment, functional limitation or disability. ex. impairment, activity limitation, participation restrictionmeasuresWhat is necessary for results to be valid?-subjects with all stages of the condition -investigators evaluated for the reliability of the measure -compares results from the index clinical measure to results from a gold standard clinical measure -were the results blind -was the time between the index clinical measure and gold standard short enough to minimize change -did investigators confirm their findings with a new set of subjects?Ability of the test to correctly identify (+ test result) in someone with the disorder. screening. has false negatives. a.
