QOLIBRI overall scale
The QOLIBRI-OS assesses a similar construct to the QOLIBRI total score and can be used as a brief index of HRQoL for traumatic brain injury TBI 1).
The results show that, despite marginal misfits to the model, the six items representing the QOLIBRI-OS could establish a Rasch scale 2).
A study examined the application of the six item QOLIBRI-OS in patients after aneurysmal subarachnoid hemorrhage (aSAH). Hong Kong Chinese aSAH patients were evaluated prospectively within the chronic phase of 1 year after aSAH in this multi-center observational study. Cronbach's α was 0.88, and correlations were satisfactory for all six items. QOLIBRI-OS demonstrated good criterion validity with other 1 year outcome assessments. In conclusion, QOLIBRI-OS can be used as a brief index for disease-specific HRQoL assessment after aSAH. Further validation in another population of aSAH patients is recommended 3).
