Three relatively simple procedures derived from the experimental analysis of behavior are described with clinical illustrations: (1) a specific, operational definition of the patient's problem; (2) a specific, operational definition of treatment goals; and (3) establishment of a system of measurement to determine direction and magnitude of change. Through systematic application to psychiatric treatment, these procedures are designed to provide an operational technology for evaluation of therapeutic effectiveness.
