Like other practices, test-based psychological assessment has been significantly affected by the health care revolution in the United States during the past two decades. Despite new limitations on psychological services across the board and psychological testing in particular, it continues to offer a rapid and efficient method of identifying problems, planning and monitoring a course of treatment, and assessing the outcomes of interventions. This thoroughly revised and greatly expanded third edition of a classic reference, now three volumes, constitutes an invaluable resource for practitioners who in a managed care era need to focus their testing not on the general goals of personality assessment, symptom identification, and diagnosis so often presented to them as students and trainees, but on specific questions: What course of treatment should this person receive? How is it going? Was it effective? New chapters describe new tests and models and new concerns such as ethical aspects of outcomes assessment. Volume I reviews general issues and recommendations concerning the use of psychological testing for screening for psychological disturbances, planning and monitoring appropriate interventions, and the assessing outcomes, and offers specific guidelines for selecting instruments. It also considers more specific issues such as the analysis of group and individual patient data, the selection and implementation of outcomes instrumentation, and the ethics of gathering and using outcomes data. Volume II discusses psychological measures developed for use with younger children and adolescents that can be used for the purposes outlined in Volume I; Volume III, those developed for use with adults. Drawing on the knowledge and experience of a diverse group of leading experts--test developers, researchers, clinicians and others, the third edition of The Use of Psychological Testing for Treatment Planning and Outcomes Assessment provides vital assistance to all clinicians, and to their trainees and graduate students.
