criterion-related validity used to predict performance in a real-life task at a future time. The final type of validity we will discuss is construct validity . Predictive validity in modern validity theory. This is a common method of developing validity evidence for employment tests: A test is administered to incumbent employees, then a rating of those employees' job performance is, or has already been, obtained independently of the test (often, as noted above, in the form of a supervisor rating). Predictive Validity – Research data is collected on people new to the job to determine how well the assessment predicted their success down the road. In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. Validity of psychological assessment: Validation of inferences from persons’ responses and performances as scientific inquiry into score meaning. Predictive definition is - of, relating to, or usable or valuable for prediction. It is a type of criterion study. This article is a part of the guide: [ vah-lid´ĭ-te] the extent to which a measuring device measures what it intends or purports to measure. How to use predictive in a sentence. In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure.[1][2]. Predictive validity is similar to concurrent validity in the way it is measured, by correlating a test value and some criterion measure. Predictive validity typically refers to the prediction of treatment effects in human subjects on the basis of treatment effects in animals. The ultimate aim of criterion validity is to demonstrate that test scores are predictive of real-life outcomes. In a study of concurrent validity the test is administered at the same time as the criterion is collected. Also called concrete validity, criterion validity refers to a test’s correlation with a concrete outcome. Predictive validity shares similarities with concurrent validity in that both are generally measured as correlations between a test and some criterion measure. Meaning of Predictive validity. This is unlike concurrent validity that compares results almost simultaneously. [1]For example, the validity of a cognitive test for job performance is the correlation between test scores and, for example, supervisor performance ratings. Predictive validity is the extent to which one test can be used to predict the outcome of another on some criterion measure. Predictive analytics is the use of data, statistical algorithms and machine learning techniques to identify the likelihood of future outcomes based on historical data. … Note the possibility for restriction of range both in test scores and performance scores: The incumbent employees are likely to be a more homogeneous and higher performing group than the applicant pool at large. face validity, content validity, predictive validity, concurrent validity, convergent validity, discriminant validity (are you measuring what you are intending to measure) ... To understand the traditional definition of construct validity, it is first necessary to understand what a construct is. ). Predictive validity is important in the business and academic sectors where selecting the right candidate or accepting the right students is important. Predictive Validity Predictive validity is the extent to which performance on a test is related to later performance that the test was designed to predict. See: Criterion-related standard used to predict performance in a real-life task at a future time. Criterion validity is the most important consideration in the validity of a test.

A predictive validity study entails determining how well a certain measure, metric or statistic can predict future behavior. More information, and an explanation of the relationship between variance and predictive validity, can be found here. Like concurrent validity, predictive validity tests an assessment against a criterion.Unlike concurrent validity, this criterion exists in the future. Another relevant example is SAT scores: These are validated by collecting the scores during the examinee's senior year and high school and then waiting a year (or more) to correlate the scores with their first year college grade point average. In a strict study of predictive validity, the test scores are collected first; then at some later time the criterion measure is collected.
