The psychometric properties of the Quality of Life Inventory in an Australian community sample

The Quality of Life Inventory (QOLI, Frisch) is an importance-weighted measure of life satisfaction that has been found to possess adequate psychometric properties in US and clinically-based samples. The current study aimed to investigate the normative distribution, factor structure and key psychometric properties of the QOLI in an Australian general community sample. Results indicated that the Australian sample (n = 259) reported slightly better quality of life than the US-based standardisation sample. Confirmatory factor analyses showed that a three-factor model provided the best fit for the data. Psychometric properties were all generally found to be adequate and close to Frisch’s reported levels. In conclusion, this study indicated that the QOLI may be used in the Australian context with confidence. Future research could examine the clinical utility of the three-factor model.
