content validity outcome measure includes all the characteristics it purports to measure
criterion validity establishes the outcome measure by comparing it to a more established gold
standard measure
construct validity the ability of a measure to assess an abstract characteristic or concept
relative reliability if measurement is reliable, individual measurements within a group will maintain
their position within the group upon repeated measurement
inter-rater, intra-rater and test-retest
intraclass correlation coefficient (ICC) how is reliability normally measured?
closer to 1 what is considered a better value for ICC?
internal consistency the extent to which multiple items within an outcome measure reflect the same
construct (are all the different items actually related to what you are trying to
measure?)
cronbach alpha what do we use to measure internal consistency?
closer to 1 what value of cronbach alpha is interpreted as being highly correlated?
absolute reliability degree to which scores vary across repeated measurements (more applicable
clinically)
standard error of measurement (SEM) how do we measure absolute reliability? estimate of the extent to which
observed scores vary around the "true" score
lower SEM this value in SEM shows that the measure is more responsive to change,
because there are smaller measurement errors (higher or lower)
minimal detectable change indicates the amount of change required to exceed measurement variability
