ABSTRACT
This chapter discusses the tests that have been commonly used for anxiety, and some of the findings related to those tests. The Minnesota Multiphasic Personality Inventory (MMPI), the Cattell tests, and Spielberger’s State-Trait Anxiety Index have been the main tests used. The anxiety measure derived from the MMPI that is best known and that has been most widely used is the Taylor Scale of Manifest Anxiety. Generally, the method of scale derivation that is most acceptable among psychologists is to select items that make the scale correlate highly with an external criterion. One way to classify anxiety measures is in terms of generality: scales can measure anxiety in general; anxiety at a middle level of generality; or anxiety with a specific content. A research project on the diagnosis or treatment of anxiety can score all seven, or eight, or nine scales, as well as compute the score on the second-order anxiety factor.
