Purpose/Objective:
Asian Americans and Pacific Islanders (AAPIs) have been underrepresented in rehabilitation research, resulting in a limited understanding of the long-term effects of traumatic brain injury (TBI) in this population. The current study bridges this gap by examining demographic and injury-related factors predicting life satisfaction trajectories over the first 10 years after TBI in AAPIs.
Research Method/Design:
The sample consisted of 381 AAPI-identifying individuals with moderate-to-severe TBI who were enrolled in the National Institute on Disability, Independent Living, and Rehabilitation Research-funded TBI Model Systems national study and had data for at least one Satisfaction with Life Scale total score at any time point (i.e., years 1, 2, 5, or 10). Hierarchical linear models examined baseline predictors of life satisfaction trajectories over the 10 years post-TBI and whether these predictors interacted with time.
Results:
Overall, life satisfaction remained stable over time. Higher overall life satisfaction trajectories were seen among AAPIs who had been married at baseline, had higher educational attainment, had been employed at injury, had low annual earnings, and had no pre-TBI mental health treatment history. Nativity/country of birth was not a significant predictor of life satisfaction trajectories when controlling for other demographic factors. None of these predictors interacted with time, suggesting no differential change in life satisfaction as a function of these predictors.
Conclusions/Implications:
The findings provide valuable insights into culturally sensitive rehabilitation approaches for AAPIs with TBI by highlighting key risk and protective factors associated with long-term life satisfaction. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
