Constructs and Construct Validation: Definitions and issues

This article presents a definition of constructs, construct validity, and wn- struct validation and traces some of the historical treatments of the terms. It is argued that construct validity and validation procedures can be particularly useful in personnel-testing contexts, where jobrelatedness is required. Several examples are presented using sophisticated modeling procedures along with other kinds of data to illustrate how evidence to show job relatedness through construct validation might be developed. Several cautions are extended re- garding the use of these statistical modeling procedures.
