Ed Hoffman, a clinical psychologist, professor, and author, has combined contemporary psychological research and business developments with a straightforward examination of the wide-ranging realm of psychological tests. Hoffman explains, without jargon or clinical terminology, the purpose, construction, relative validity, and actual usefulness of 42 of the major assessment tools currently being used. These include: the Beck Anxiety and Depression Inventories; the California Personality Inventory; the Hogan Personnel Selection series; the NEO Personality Inventory (Revised); the Positive and Negative Affect Test; the PSC Survey of ADT (Alienation, Drinking/Drugs and Trustworthiness); the Survey of Work Styles; the Work Stress Inventory and 33 others. In addition Hoffman addresses specifics such as whether a given test is reliable, if (and how) it might be "beaten" by test-makers, and the legal ramifications of how tests are used.
