&NA;This study evaluated quality of life in 78 patients with closed head injury (CHI) 2 to 4 years postinjury. Using both interview data and mean data from the Sickness Impact Profile questionnaire, impaired quality of life was observed in the areas of psychosocial functioning, social role functioning, leisure activities, and, to a lesser extent, physical functioning, during chronic phases of recovery. Relatives and close friends reported by means of the Katz Adjustment Scale that the CHI patients showed a series of negative behavioral symptoms 2 to 4 years postinjury. These data suggest that CHI patients may experience impaired quality of life in a number of domains well beyond the acute postinjury phases. An attempt was also made to compare patients' and relatives' reports of patient quality of life. Preliminary analyses indicated modest correspondence between relatives' and patients' ratings of some areas of postinjury dysfunction, including cognitive and behavioral slowing and social withdrawal.
