As the classic in the field for over 20 years, Behavioral Assessment: A Practical Handbook, Fourth Edition retains its empiricism and practical focus by including the latest research on conceptual issues and strategies of behavioral assessment. The editors and expert chapter authors have provided a thorough detail of the instruments and goals of assessment, along with an evaluation of treatment of anxiety, depression, social skills, health-related disorders, appetite disorders, marital and sexual dysfunctions, child behavior problems, and assessment of older adults. To give the reader the depth and breadth of current thinking, three new chapters have been added covering behavioral neuropsychology, biological assessment, and assessment of older adults.
