In light of the increased survival rate of head trauma patients, research in the area of behavioral treatment is much needed. This case study demonstrates a two-phase treatment approach. Phase 1 consisted of developmental stimulation, utilizing the Kaufman Developmental Scale, and Phase 2 consisted of a behavior modification approach to change personal and social behaviors. In response to developmental stimulation, the patient achieved a higher level of developmental functioning, experienced success, and demonstrated concomitant positive behavioral changes. Once the patient reached a developmental plateau, behavioral modification was initiated, and the patient demonstrated significant further positive behavioral changes. It is believed that the patient's positive response to treatment in Phase 2 was predicated on his success in Phase 1.Interest in and knowledge of brain-behavior relationships have increased tremendously in the past decade, while remediation techniques for organically impaired individuals have lagged behind. Horton and Howe (1981) noted that a striking omission from current behavior therapy has been attention to the brain-damaged patient. Walsh (1978) indicated that rehabilitation services for head trauma patients tend to focus heavily on physical disabilities rather than on intellectual and emotional handicaps.The prognosis for severely brain-injured patients, especially for their social and vocational development, is poor (Tobis, Puri, & Sheridan, 1982). The current state of remediation and rehabilitation programs for these patients is not yet established on a solid scientific foundation. Rather, clinicians are relegated to a trial-and-error process based on scientific knowledge, theory, and educated guessing in an attempt to demonstrate that their efforts will lead to a more detailed specification of methods (Diller & Gordon, 1981). The case study presented here, which was undertaken as a pilot project, describes a unique two-phase treatment used with a head trauma patient.The first phase utilized the Kaufman Developmental Scale (KDS) as a didactic developmental teaching approach (Kaufman, 1975). The goal was to teach developmental behaviors that had regressed following the head trauma so that the patient would have greater self-confidence and a feeling of accom-
