Extent to which a measurement corresponds to theoretical concepts (constructs) concerning the phenomenon under study; for example, if on theoretical grounds, the phenomenon should change with age, a m [..]

Seeks an agreement between a theoretical concept and a specific measuring device, such as observation.

the degree to which the testing tool and measurement tool used in a study accurately reflect the conceptual question of interest. For instance, asking people whether they feel that a product is usable [..]

The general validity of a measuring device. Construct validity answers the question of whether or not the measuring device actually measures the construct under question.

The extent to which a measurement reflects the specific underlying construct it purports to assess. Construct validity requires gradual accumulation of evidence from a variety of sources.

the magnitude to which an analysis or tool is able to gauge an abstract characteristic, capacity, or construct.

Construct Validity refers to the ability of a measurement tool (e.g., a survey, test, etc) to actually measure the psychological concept being studied. In other words, does it properly measure what it [..]

A form of validity for an operational definition. If a test has "construct validity" then it measures what it says it measures, or rather there is evidence that it measures what it says it measures. There are various standard ways of trying to establish that a test has "construct validity." One standard way is triangulation.

The degree to which a variable, test, questionnaire or instrument measures the theoretical concept that the researcher hopes to measure. For example, if a researcher is interested in the theoretical c [..]

A construct refers to the underlying trait (e.g., intelligence, sociability) assumed to be measured by an assessment. Construct validation involves collecting evidence to determine whether the assessm [..]

A method of assessing validity by examining how well the test measures the underlying construct. See Box 7.3.

The degree to which a survey question adequately measures an intended hypothetical construct. This may be assessed by checking the correlation between observations from that question with observations [..]

An instrument is said to possess construct validity if it can be demonstrated that it indeed measures the particular abstract concept, or construct, it purports to measure. For instance, an instrument that claims to measure the construct of pain would need to demonstrate a positive correlation with other indicators of the experience of pain.

If a theoretical concept or working hypothesis (a Construct

is a type of validity that refers to the degree to which a test captures the underlying construct purportedly measured by the test.
