Study investigated the predictive value of pre-injury factors for satisfaction with life (SWL) at 1-year posttraumatic brain injury (TBI). Data were collected during inpatient rehabilitation and at 1-year post-TBI from 444 community-dwelling individuals, aged 16 to 64 years, who were enrolled in the Traumatic Brain Injury Model Systems program between October 2007 and October 2008. Participants were administered the Satisfaction With Life Scale (SWLS) as part of the follow-up interview. Hierarchical stepwise linear regression revealed that injury-related and demographic variables did not predict SWLS scores. In contrast, the pre-injury functioning (education, productivity/employment) and pre-injury conditions (psychiatric and substance use problems, severe sensory dysfunction, learning problems, prior TBI) each contributed significantly to the explained variance in SWLS scores. Pre-injury functioning accounted for 2.9 percent of the variance and pre-injury conditions for 3.8 percent. The authors conclude that although their contributions are small, pre-injury functioning and pre-injury conditions are important to consider in the prediction of SWL after TBI.
