The primary purpose of this revision remains identical to that of the first edition—to show how key personality, cognitive/behavioral, and vocational tests/assessment procedures can be used by counselors in their work with clients. Too often, assessment books only provide the reader with information about tests and assessment procedures. They do not, however, take the next step—showing readers how these tests/assessment procedures can be used and integrated into the actual work of counseling. This revision is designed to fill that void. Chapter authors, all of whom are experts in their respective topic areas, share the theoretical and research backgrounds about a particular test/assessment procedure and then provide a case example or examples to show how assessment data can be meaningfully incorporated into the counseling process.
