An investigation of the use of a behavior modification approach in the treatment of a psychotic episode on an open, short-term treatment ward. A reinforcement regimen is examined in which points given out by the nurses on a fixed interval schedule served as an immediate reward, and more "valuable" rewards could later be purchased with these points. Particular attention is paid to the problem of staff cooperation and the staff's rewards. The ways in which this regimen provided interlocking rewards for the patient, staff, and physicians is evaluated.
