ABSTRACT
This chapter discusses validation largely within the context of personnel selection. The validity strategies used reflect consideration of the contextual factors and others. There are a great many meta-analyses of the criterion-related validity of various constructs in the prediction of job performance and many thousands of primary studies. Validity evidence can also take the form of an examination of the response processes involved in responding to an item. Similar to looking at the internal structure of a test, researchers can also examine its external validity by correlating the test results with job performance measures. In practice, criterion-related validity studies are often criticized for failing to adequately address validity issues surrounding the criterion measure(s) used. Transportability and synthetic validity are similar notions; in transportability, one is taking the entire results of a validation study to justify use of a test or test battery in a new situation.
