Question

A well-designed functional capacity evaluation provides objective information regarding the client's ability to work. The testing protocol used in the functional capacity evaluation should be reliable and valid. It is important for the OTR to consider the protocol's psychometric properties. Which of the following will provide the OTR with the information regarding the stability of the protocol's score when the protocol is administered on two separate sessions by the OTR?

1) Interrater reliability
2) Criterion validity
3) Intrarater reliability
4) Predictive validity

Answer 1

Intrarater reliability provides information on the consistency of a protocol's score across different sessions administered by the same OTR, distinguishing it from interrater reliability and forms of validity such as criterion and predictive validity.

Step-by-step explanation:

The information regarding the stability of a protocol's score when the protocol is administered on two separate sessions by the same occupational therapist (OTR) can be determined by examining the intrarater reliability of the functional capacity evaluation. This type of reliability assesses whether the same evaluator is consistent across multiple assessments. It differs from interrater reliability, which refers to the agreement between different evaluators, and various forms of validity such as criterion validity and predictive validity, both of which concern how well an evaluation or test predicts outcomes or correlates with established standards.
