The use of psychological tests in the assessment of the human condition is one of the hallmarks of clinical psychology. Indeed, expertise in test-based psychological assessment can be said to be the unique contribution that clinical psychologists make to the behavioral health-care field. For decades, clinical psychologists and other behavioral health-care providers have come to rely on psychological assessment as a standard tool to be used with other sources of information for multiple purposes. This chapter provides students and practitioners of clinical psychology with an overview of the various ways in which psychological assessment is currently being used as an adjunct for the treatment of behavioral health problems. This includes a discussion of psychological assessment as a tool for screening and diagnosis, treatment planning, treatment intervention, treatment monitoring, and outcomes assessment. The current status of test-based psychological assessment and current technologies that facilitate the administration and scoring instruments and the reporting psychological assessment data are also discussed.
