With screening or diagnostic instruments, the concept indicating the instruments' ability to correctly identify a "case" (i.e., to screen in or diagnose a condition correctly) is which of the following?
A) Sensitivity
B) Stability
C) Specificity
D) Sensibility
A
Feedback:
Sensitivity is the instrument's ability to identify a case correctly (i.e., its rate of yielding true positives). Specificity is the instrument's ability to identify non-cases correctly (i.e., its rate of yielding true negatives). 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. There is no research term known as sensibility.
