PURPOSE/OBJECTIVE: Satisfaction with life (SWL) is an important measure of
outcome in rehabilitation. Previous research suggests that those with a history
of traumatic brain injury (TBI), even mild TBI, report lower levels of life
satisfaction when compared with the noninjured population. Although is it
possible that TBI has a direct effect on SWL, various medical and psychosocial
factors commonly affecting those recovering from TBI likely contribute to SWL.
RESEARCH METHOD/DESIGN: The present study aimed to identify factors related to
SWL in 95 veterans of Operation Enduring Freedom (OEF), Operation Iraqi Freedom
(OIF), and Operation New Dawn (OND) with a history of mild TBI.
RESULTS: Regression analyses indicated that headache impact, pain interference,
sleep quality, posttraumatic stress symptom severity, and social support were all
significantly related to SWL. However, when secondary analyses were conducted
including posttraumatic stress symptom severity as a covariate before the entry
of other predictors, only sleep quality and social support remained significantly
associated with SWL.
CONCLUSIONS/IMPLICATIONS: These results indicate the importance of properly
identifying and treating symptoms of posttraumatic stress in veterans with a
history of mTBI, as posttraumatic stress symptoms appear to be strongly related
to SWL in those with a history of mild TBI. Optimizing sleep quality and social
support may also be important in improving SWL.
