Assessment has always played an important role in counseling. This book provides information about the various psychological assessment procedures that are relevant for practicing counselors. The text deals with the use of tests that are most often employed by counselors and it includes case studies. Its purpose is to help counselors become better consumers and interpreters of psychological and educational tests and assessment procedures. It emphasizes the selection, interpretation, and communication of psychological test results and also details the importance of integrating test results with other information about the client. It is not designed to be a text book or desk manual on the various tests themselves. The first four chapters introduce the reader to basic concepts in psychological assessment and to the statistical knowledge needed to select and interpret tests. Chapters 5 through 15 constitute the bulk of the book. Here, over 100 tests and other assessment measures are examined. The assessments are divided into three categories: cognitive, career and life planning, and personality. In chapters 16 through 18, professional practices and considerations are explored, including analyses of cultural bias, communication of test results, and ethical and social issues in testing. (Contains roughly 500 references and a comprehensive index.) (RJM)
