Current status and new developments in behavioral assessment for clinicians and researchers are discussed. The field of behavioral assessment has attained a recognizable identity in recent years. Behavioral assessment can be defined as the identification of meaningful response units and their controlling variables for the purposes of understanding, and altering, behavior. Practitioners have become disillusioned with the impracticality of obtaining and using behavioral assessment devices. However, there is improved accessibility of behavioral assessment devices as a result of many books and journals now available with this information. The author recommends development of a behavioral assessment kit to further improve accessibility. Researchers are disappointed with the results when psychometric criteria are used to evaluate the quality of behavioral assessment techniques. More appropriate evaluative criteria are being developed to assist researchers. These criteria include accuracy standards, individualized approaches, identification of controlling variables, and treatment validity. (DWH)
