Flashcards in Reliability and Validity Deck (10)
ICC model 1
each subject tested by different raters.
assess difference among subjects
ICC model 2
each subject tested by same raters
*raters and subjects random
assess interrater reliability
ICC model 3
each subject tested by same rater
used to measure intrarater reliability.
measuring change order
MPDD -> MDD (smallest change that can be interpreted as any inprov. or decline.) -> MCID (meaningful change)
probability of getting a true positive.
1-this = false negative rate
probability of getting a true negative.
1-this = false positive rate
high specificity, positive test, rule in
high sensitivity, negative test, rule out
positive likelihood ratio
odds of a disease are increased if a test is positive
true positive rate/false positive rate
sensitivity/ (1- specificity)
