Which of the following demonstrates interrater reliability and construct validity for an instrument designed to...

Interrater reliability refers to the degree to which two or more independent reviewers or abstractors provide consistent results when reviewing the same data or records. Option A clearly defines this concept by stating that "two or more abstractors enter identical responses when reviewing the same record," which is the hallmark of interrater reliability (The Joint Commission, 2024; NAHQ CPHQ Study Guide).

Construct validity assesses whether the instrument truly measures the quality of care it is intended to measure. The description in option A—"The tool measures the quality of care which the measure developers intended to measure"—directly reflects construct validity, confirming the instrument's alignment with its intended purpose (Agency for Healthcare Research and Quality [AHRQ], 2023; National Quality Forum [NQF]).

Other options do not simultaneously address both interrater reliability and construct validity as directly and accurately as option A. For example:

Option B describes reliability but does not clearly relate to interrater reliability and its validity statement focuses on public relevance rather than intended measure accuracy.

Option C discusses concordance and statistical inferences, which are more related to validity types other than construct validity.

Option D addresses data integrity but does not fully cover interrater reliability or construct validity.
