how to measure criterion validity

For this reason, many employers rely on validity generalization to establish predictive validity, by which the validity of a particular test can be generalized to other related jobs and positions based on the testing provider’s pre-established data sets. While translation validity examines whether a measure is a good reflection of its underlying construct, criterion-related validity examines whether a given measure behaves the way it should, given the theory of that construct. To help understand these three different approaches, consider the construct of "satisfaction." Concurrent validity: This occurs when criterion measures are obtained at the same time as test scores,   indicating the ability of test scores in estimating an individual’s current state. What is a criterion? Second, I make a distinction between two broad types: translation validity and criterion-related validity. Criterion Validity. A criterion is the standard against which the test is compared. The skill is often focused on a business outcome. Criterion validity is often divided into concurrent and predictive validity based on the timing of measurement for the "predictor" and outcome. The validity of inferences made from assessment data is commonly measured using one (or more) of three methods: intervention study, differential-population study, and related-measures study (criterion validity). However, it can be useful in the initial stages of developing a method. … Two types of criterion validity are predictive and concurrent validity. Measures may have high validity, but when the test does not appear to be measuring what it is, it has low face validity. In the context of questionnaires the term criterion validity is used to mean the extent to which items on a questionnaire are actually measuring the real-world states or events that they are intended to measure. Criterion validity:In this validity, the extent to which the outcome of a specific measure or tool corresponds to the outcomes of other valid measures of the same concept is examined. If the test is capable of repeatedly predicting performance, then you know that it works for the purpose. Criterion or predictive validity measures how well a test accurately predicts an outcome. Validity refers to the degree to which an instrument accurately measures what it intends to measure. In contrast to content validity, criterion or predictive validity is determined analytically. For example, people’s scores on a new measure of test anxiety should be negatively correlated with their performance on an important school exam. This type of validity is called criterion-related validity, which includes four sub-types: convergent, discriminant, concurrent, and predictive validity. Measures of intelligence, personality, vocational interests, and so forth that lack reliability and validity are worse than useless. Criterion validity is the extent to which people’s scores on a measure are correlated with other variables (known as criteria) that one would expect them to be correlated with. If a test is highly correlated with another valid criterion, it is more likely that the test is also valid. Predictive validity is a measure of how well a test predicts abilities, such as measuring whether a good grade point average at high school leads to good results at university. Criterion validity is the extent to which people’s scores on a measure are correlated with other variables (known as criteria) that one would expect them to be correlated with. For example, people’s scores on a new measure of test anxiety should be negatively correlated with their performance on an important school exam. Criterion validity. Construct validity determines the extent to which a new measures performs as expected with regard to other variables. There are three sub-sets of criterion validity; convergent, divergent, and predictive. In addition, he covers issues such as: how to measure reliability (including test-retest, alternate form, internal consistency, inter-observer and intra-observer reliability); how to measure validity (including content, criterion and construct validity); how to address cross-cultural issues in survey research; and how to scale and score a survey. This form of validity is related to external validity, discussed in the next section. Criterion validity evaluates how closely the results of your test correspond to the results of a different test. Criterion validity in comparing different measuring instruments. Concurrent validity and predictive validity are forms of criterion validity. Criterion validity of a test means that a subject has performed successfully in relation to the criteria. [2] : page 282 Concurrent validity refers to a comparison between the measure in question and an outcome assessed at the same time. Extended DISC® International conducts a Predictive Validity study on a bi-annual basis. For example, a survey is being conducted by a news agency for assessing the political opinion of the voters in a town. Predictive Validity – This measures how likely the instrument measures a variable that can be used to predict a future related variable. For example, if a pre-employment test accurately predicts how well an employee will perform in the role, the test is said to have high criterion validity.
