137. Does mental health status moderate the relationship between traumatic brain injury and life satisfaction?
Traumatic brain injury (TBI) history has been linked to reduced cognitive performance and poorer quality of life. While this link has been established, there is not much known about this relationship in older adult populations experiencing normal cognitive decline. In the current study, mental status was predicted to moderate the relationship between TBI history and life satisfaction among older adults. Additionally, details of the injury - years since injury and time spent unconscious - were expected to play a role in this relationship. The sample consisted of 320 respondents, 58% women, from 2014 cohort of the Health and Retirement Study (HRS), with 134 reporting at least one TBI in their lifetime. Respondents' age ranged from 58 to 94 (M = 75.78, SD = 6.88). There were no significant relationships found between any of the TBI variables with mental status, life satisfaction, or the interaction of the two. While insignificant, these results yield important findings. The results lend support to more positive long-term outcomes for those with a history of TBI than initially expected, especially if the TBI was mild and resulted in no loss of consciousness or a loss of consciousness less than 5 hours.
