What is one way to obtain a criterion validity estimate ass

What is one way to obtain a criterion validity estimate? - assess the underlying construct on which the test is based and correlate these scores with test scores or is it select a criterion and correlate scores on the test with scores on the criterion...? I lean towards the first answer

Solution

Criterion-related validity refers to the extent to which one measure estimates or predicts the values of another measure or quality. The first measure is often called the estimator or the predictor variable. The second measure is called the criterion variable in cases when a decision must be made or when the measure is regarded as valid. In some cases, neither measure has well-developed validity evidence, and there is no genuine criterion variable. There are two types of criterion-related validity: concurrent validity and predictive validity. The simple distinction between the two types concerns the time interval between obtaining the first and the second set of measurements. For concurrent validity, the data from both measures are collected at about the same time. For predictive validity, the data from the criterion measure are collected some period of time after the data of the predictor variable

Criterion or concrete validity is the extent to which a measure is related to an outcome. Criterion validity is often divided into concurrent and predictive validity.Concurrent validity refers to a comparison between the measure in question and an outcome assessed at the same time. In Standards for Educational & Psychological Tests, it states, \"concurrent validity reflects only the status quo at a particular time.\"Predictive validity, on the other hand, compares the measure in question with an outcome assessed at a later time. Although concurrent and predictive validity are similar, it is cautioned to keep the terms and findings separated. \"Concurrent validity should not be used as a substitute for predictive validity without an appropriate supporting rationale.\"

An example of concurrent validity is a comparison of the scores of the CLEP College Algebra exam with course grades in college algebra to determine the degree to which scores on the CLEP are related to performance in a college algebra class. An example of predictive validity is a comparison of scores on the SAT with first semester grade point average (GPA) in college; this assesses the degree to which SAT scores are predictive of college performance
