Center has been investigating the nature, causes, predictors, and treatment of functional disability after minor traumatic brain injury (TBI). This article clarifies distinctions among minor head injury, mild traumatic brain injury, postconcussion syndrome, and posttraumatic stress disorder; identifies methodological and information-processing issues in minor TBI; describes four stages of clinical research related to minor TBI; and presents a neuropsychological model of functional disability after minor TBI, with implications for assessment and treatment.

The purposes of this study were to (a) develop and implement an effective program of psychosocial intervention for adult cancer patients, (b) evaluate the impact of this program in ameliorating the psychosocial problems of cancer patients, and (c) develop procedures for documenting the intervention process. Three cancer sites were investigated: breast, lung, and melanoma. Half of the patients (n = 157) received psychosocial evaluation and a systematic program of psychosocial rehabilitation (intervention group), and the remaining half (n = 151) received only the evaluation (control group). There were no significant demographic or medical (e.g., prognosis, staging of disease, etc.) differences between the control and intervention groups. Data analysis indicated that (a) the evaluation instruments were sensitive to the course of psychosocial treatment of the cancer patient; (b) intervention effectively ameliorated some of the psychosocial problems reported by patients; and (c) patients in the intervention group evidenced a more rapid decline of negative affect (i.e., anxiety, hostility, depression), a more realistic outlook on life, a greater proportion of return to previous vocational status, and a more active pattern of time usage than patients in the control group.The psychosocial impact of cancer on the (1977) indicated that 25% to 30% of the patient has been well described in both mastectomy patients that they interviewed the professional (Craig & Abeloff, 1974; remained emotionally upset 1 year follow-
