The extent to which a measurement reflects the specific intended domain of content (Carmines & Zeller, 1991, p.20).

An approach to validating a measure by determining the adequacy with which the domain of the characteristic is captured by the measure; it is sometimes called face validity.

A measurement device’s ability to be generalized to the entire content of what is being measured.

The extent to which a measurement reflects the specific intended domain of content. Stated as a question: Do the ... thoroughly cover all relevant aspects of the conceptual domain they are intended to [..]

the degree to which an analysis gauges a symbolizing example of the topic content or behavior that is being analyzed.

Content validity is an important research methodology term that refers to how well a test measures the behavior for which it is intended. For example, let's say your teacher gives you a psycholog [..]

The extent to which the measurement incorporates the domain of the phenomenon under study. For example, a measurement of functional health status should embrace activities of daily living, occupational, family, and social functioning, and so on.

Similar to face validity except that the researcher deliberately targets individuals acknowledged to be experts in the topic area to give their opinions on the validity of the measure.

Evidence (based on job analysis and expert judgment) the choice of items or tasks included in the assessment logically match or represent those tasks or competencies required by the job.

The extent to which the measurement incorporates the domain of the phenomenon under study. For example, a measurement of functional health status should embrace activities of daily living, occupationa [..]

A method of assessing validity by inspecting the content of a measurement procedure. See Box 7.3.

A conceptual or non-statistical validity based on a systematic analysis of the test content to determine whether it includes an adequate sample of the target domain to be measured. An adequate sample involves ensuring that all major aspects are covered and in suitable proportions.

A typical occasion for interest in content validity is that of an achievement test of subject matter mastery by students. This type of validity refers to the degree of correspondence that exists between (a) an instrument’s test items and (b) the learning/performance objectives and associated content coverage taught to the students and for which the [..]

Representativeness or sampling adequacy of the measurement instrument's content.
