The document discusses behavioral assessment in clinical psychology. It begins with a brief history of behaviorism from the 1930s to 1953. It then describes three key aspects of behavioral assessment: it focuses on interactions between situations and behaviors to effect change, interprets test responses as samples of behavior rather than signs of internal processes, and uses functional behavioral analysis models like SORC to isolate and understand target behaviors. Finally, it outlines several common behavioral assessment methods, including behavioral interviews, observational methods under both naturalistic and controlled conditions, controlled performance techniques, and self-monitoring.
