Primary objective: To compare the pre-injury subjective quality of life (SQOL) estimates of a representative sample of adults with TBI, using the Quality of Life Inventory (QOLI) with the measure's generic US-based norms and identify a factor structure for the instrument within the local TBI population.Research design: A population-based, cross-sectional design conducted with data collected by the Neurotrauma Register of Tasmania (2003-2005).Methods and procedures: As soon as possible following their emergence from post-traumatic amnesia, 470 participants provided pre-injury estimates of their SQOL using the QOLI. The distribution of this sample was compared with the measure's normative distribution. The sample was separated evenly into two groups (n = 235) for separate exploratory and confirmatory factor analyses.Main outcomes and results: Small differences were found between the pre-injury estimates and the QOLI's US-based normative distribution. Corrections were provided to clinical classification ranges for this population. Three factors were identified and confirmed for the QOLI in separate TBI samples.Conclusion: The results of this study support the use of the QOLI in measuring SQOL in TBI rehabilitation and outcomes research.
