Content |
refers to the extent to which the questions or behaviors selected are representative of what you intend to measure |
|
|
Criterion |
refers to its ability to predict an individual's performance: *concurrent: predict current performance *predictive: predicts future performance *discriminant or known-groups: distinguishes between groups known to have different amounts of whatever is supposedly measured |
|
|
Construct |
your operationalization accurately reflects its constructs. Established by setting up hypotheses about the behavior of persons with high or low scores on the measure. These hypotheses are then tested. *convergent validity: highly correlated with another measure of the same concept *Divergent/discriminant validity: not significantly correlated with variables with which it should not be correlated |
|
|
Systematic measurement error relates to validity |
Not determined by chance but is an inaccuracy inherent in the system (e.g. something wrong with the instrument or the instrument wrongly used by the clinician) |
