Health-related quality of life after traumatic brain injury: Italian validation of the QOLIBRI

The QOLIBRI (Quality of Life after Brain Injury) is a new international health-related quality of life (HRQoL) instrument developed for assessing the consequences of traumatic brain injury (TBI). We report the results of the Italian validation of the QOLIBRI. A total of 147 participants with TBI who had previously been discharged from the Santa Lucia Foundation rehabilitation hospital were recruited to investigate the concurrent validity of the Italian version of the QOLIBRI and to compare this instrument with several functional and cognitivebehavioral scales, taking into account various clinical parameters. The QOLIBRI met the standard criteria for internal consistency, homogeneity and test-retest reliability. The results suggest that it is very sensitive in relation to outcome as measured by the Extended Glasgow Outcome Scale (GOS-E) and other instruments for functional assessment of disability, emotions and subjective health status, including the Hospital Anxiety and Depression Scale and the Short-Form 36. The QOLIBRI avoids some of the limitations of traditional scales for quantifying residual functional capacity, such as the Glasgow Outcome Scale and the GOS-E, and may contribute to the achievement of better quality-controlled care, medical decision-making, rehabilitation planning, and measurement of well-being and HRQoL from the patient's perspective. However, a longitudinal study is needed to assess the responsiveness of the QOLIBRI to changes over time.
