Subjective well-being has been studied in many health populations, including persons with developmental disabilities, cardiac disease, arthritis, and changes in function due to aging. Among persons with disabilities, those with conditions affecting physical function have been more widely investigated than those with cognitive disabilities. Health status, income, and social activity have each been found to be highly related to subjective well-being. Results of a preliminary study we conducted of persons with traumatic brain injuries found functional independence was not correlated with subjective well-being, despite previous studies showing "health status" to be an important mediating variable. Consistent with previous studies, income was highly related to subjective well-being. Social integration/social activity indices were related but did not appear as strong as reported in studies of aging or spinal cord injury. An interesting finding from this investigation was that time post discharge was related to subjective well-being, with a decline evident for those subjects 1-2 years post-discharge. The purpose of the current study is to (1) investigate predictive factors of subjective well-being at one year post-discharge from rehabilitation; and (2) identify factors that predict changes in subjective well-being between the first and second years.
