A
Feedback:
Internal consistency reliability, which refers to the extent to which all of the instrument's items are measuring the same attribute, is usually assessed with Cronbach's alpha. The stability aspect of reliability, which concerns the extent to which an instrument yields similar results on two administrations, is evaluated by test–retest procedures. Sensitivity is the instrument's ability to identify a case correctly (i.e., its rate of yielding true positives). Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument.
