Health-related quality of life after traumatic brain injury: Italian validation of the QOLIBRI (original) (raw)

German validation of Quality of Life after Brain Injury (QOLIBRI) assessment and associated factors

PloS one, 2017

The consequences of traumatic brain injury (TBI) for health-related quality of life (HRQoL) are still poorly understood, and no TBI-specific instrument has hitherto been available. This paper describes in detail the psychometrics and validity of the German version of an internationally developed, self-rated HRQoL tool after TBI-the QOLIBRI (Quality of Life after Brain Injury). Factors associated with HRQoL, such as the impact of cognitive status and awareness, are specifically reported. One-hundred seventy-two participants after TBI were recruited from the records of acute clinics, most of whom having a Glasgow Coma Scale (GCS) 24-hour worst score and a Glasgow Outcome Scale (GOSE) score. Participants had severe (24%), moderate (11%) and mild (56%) injuries as assessed on the GCS, 3 months to 15 years post-injury. The QOLIBRI uses 37 items to measure "satisfaction" in the areas of "Cognition", "Self", "Daily Life and Autonomy", and "Socia...

QOLIBRI Overall Scale: a brief index of health-related quality of life after traumatic brain injury

Journal of Neurology, Neurosurgery & Psychiatry, 2012

Background The Quality of Life after Brain Injury (QOLIBRI) scale is a recently developed instrument that provides a profile of health-related quality of life (HRQoL) in domains typically affected by brain injury. However, for global assessment it is desirable to have a brief summary measure. This study examined a 6-item QOLIBRI Overall Scale (QOLIBRI-OS), and considered whether it could provide an index of HRQoL after traumatic brain injury (TBI). Methods The properties of the QOLIBRI-OS were studied in a sample of 792 participants with TBI recruited from centres in nine countries covering six languages. An examination of construct validity was undertaken on a subsample of 153 participants recruited in Germany who had been assessed on two relevant brief quality of life measures, the Satisfaction With Life Scale and the Quality of Life Visual Analogue Scale. Results The reliability of the QOLIBRI-OS was good (Cronbach's a¼0.86, testeretest reliability ¼0.81) and similar in participants with higher and lower cognitive performance. Factor analysis indicated that the scale is unidimensional. Rasch analysis also showed a satisfactory fit with this model. The QOLIBRI-OS correlates highly with the total score from the full QOLIBRI scale (r¼0.87). Moderate to strong relationships were found among the QOLIBRI-OS and the Extended Glasgow Outcome Scale, . The QOLIBRI-OS showed good construct validity in the TBI group. Conclusions The QOLIBRI-OS assesses a similar construct to the QOLIBRI total score and can be used as a brief index of HRQoL for TBI. < An additional appendix is published online only.

Reference Values of the Quality of Life after Brain Injury (QOLIBRI) from a General Population Sample in Italy

2023

Traumatic brain injury (TBI) may affect the lives of the individuals concerned and their relatives negatively in many dimensions. Health-related quality of life (HRQoL) is a comprehensive and complex concept that can assess one's satisfaction with a broad range of areas of life and health. The Quality of Life after Traumatic Brain Injury (QOLIBRI) questionnaire is a TBI-specific measure for HRQoL which is used in research and health services worldwide. When evaluating self-reported HRQoL after TBI, reference values from a general population are helpful to perform clinically relevant evaluations and decisions about the condition of an affected person by comparing the patient scores with reference values. Despite the widespread use of the QOLIBRI, reference values have until now only been available for the Netherlands and the United Kingdom. The aim of this study was to validate the QOLIBRI for the general population in Italy and to provide reference values. An adapted form of the QOLIBRI was administered to 3298 Italians from a healthy general population using an online survey. Their scores were compared with those of 298 individuals post-TBI recruited within the international longitudinal observational cohort CENTER-TBI study in Italian hospitals, who completed the original questionnaire. The psychometric characteristics and the measurement invariance of the QOLIBRI were assessed. A regression analysis was performed to identify predictors relevant for HRQoL in the general population. Reference values were provided using percentiles. Measurement invariance analysis showed that the QOLIBRI captures the same HRQoL constructs in an Italian general population and Italian TBI sample from the observational Center-TBI study. Higher age, higher education and the absence of a chronic health condition were associated with higher QOLIBRI scores, suggesting better HRQoL. Reference values were provided for a general Italian population adjusted for age, sex, education and presence of chronic health conditions. We recommend using these for a better interpretation of the QOLIBRI score in clinical practice and research in Italy.

Quality of life after traumatic brain injury: The clinical use of the QOLIBRI, a novel disease-specific instrument

2010

Objective: To report the clinical use of the QOLIBRI, a disease-specific measure of health-related quality-of-life (HRQoL) after traumatic brain injury (TBI). Methods: The QOLIBRI, with 37 items in six scales (cognition, self, daily life and autonomy, social relationships, emotions and physical problems) was completed by 795 patients in six languages (Finnish, German, Italian, French, English and Dutch). QOLIBRI scores were examined by variables likely to be influenced by rehabilitation interventions and included socio-demographic, functional outcome, health status and mental health variables. Results: The QOLIBRI was self-completed by 73% of participants and 27% completed it in interview. It was sensitive to areas of life amenable to intervention, such as accommodation, work participation, health status (including mental health) and functional outcome. Conclusion: The QOLIBRI provides information about patient's subjective perception of his/her HRQoL which supplements clinical measures and measures of functional outcome. It can be applied across different populations and cultures. It allows the identification of personal needs, the prioritization of therapeutic goals and the evaluation of individual progress. It may also be useful in clinical trials and in longitudinal studies of TBI recovery.

Traumatic brain injury and quality of life: Initial Australian validation of the QOLIBRI

Journal of Clinical Neuroscience, 2011

The Quality of Life after Brain Injury (QOLIBRI) is a new international instrument for assessing quality of life after traumatic brain injury (TBI). We report first use and validation. Patients previously admitted with TBI to the Royal Melbourne Hospital, Melbourne, Australia, were randomly sampled (n = 66, 61% response rate) and administered the QOLIBRI. Fifty-five re-completed it at 2-week follow-up. QOLIBRI scales (with two exceptions) met standard criteria for internal consistency, homogeneity and test-re-test reliability. Correlations with the Assessment of Quality of Life, Short Form-36 version 2 and the Satisfaction with Life Scale were moderate. The QOLIBRI was sensitive to the Glasgow Outcome Scale -Extended scores, Hospital Anxiety and Depression scale, and measures of social isolation (Friendship Scale). There was evidence that further refinement may improve the QOLIBRI. The QOLIBRI should be considered as an outcome measure by clinicians and researchers conducting treatment trials, rehabilitation studies or epidemiological surveys into the treatment or sequelae of trauma.

Assessment of health-related quality of life in persons after traumatic brain injury -development of the Qolibri, a specific measure

2005

Background. Health-related quality of life (HRQOL) associated or not with the measurement of neuropsychological functioning is a relatively new outcome variable in the field of traumatic brain injury (TBI). In both cases, accuracy and precision are increased in outcome estimation. Validation of generic, cross-culturally (cc) administered HRQOL measures in persons after TBI is not yet well established. Disease-specific HRQOL instruments do not exist in an international context. The objective here is to present the TBI consensus group's (QOLIBRI-Group) approach in cc development of a specific HRQOL measure-the QOLIBRI (Quality of Life after Brain Injury). Methods. Special issues of TBI-specific instrument creation will be highlighted as well as cc questionnaire construction, development, translation and psychometric testing. Results. The validation process of the preliminary version of the disease-specific QOLIBRI in 15 countries and 13 languages will be described. The QOLIBRI assesses HRQOL within six domains (physical condition, thinking activities, feelings and emotions, functioning in daily life, relationships and social/leisure activities, current situation and future prospects). The QOLIBRI integrates diseasespecific issues of TBI patients, i.e. cognition, existential aspects (as the sense of self) etc., which are missing in generic tools. Conclusion. In TBI patients, generic and disease-specific aspects of HRQOL need to be assessed with measures of adequate psychometric quality, applicable across di¤erent populations and cultural conditions. The QOLIBRI is a promising instrument for sensitive patient-centered specific outcome evaluation after TBI.

Interpreting Quality of Life after Brain Injury (QOLIBRI) scores: Cross-walk with the Short Form-36

Journal of neurotrauma, 2016

The Quality of Life after Brain Injury (QOLIBRI) instruments are traumatic brain injury-specific assessments of health-related quality of life (HRQoL), with established validity and reliability. The purpose of the study is to help improve the interpretability of the two QOLIBRI summary scores (the QOLIBRI Total score and the QOLBRI Overall Scale score). An analysis was conducted of 761 patients with traumatic brain injury (TBI) that took part in the QOLIBRI validation studies. A cross-walk between QOLIBRI scores and the SF-36 Mental Component Summary norm-based scoring system was performed using geometric mean regression analysis. The exercise supports a previous suggestion that QOLIBRI Total scores < 60 indicate low or impaired HRQoL, and indicate that the corresponding score on the QOLIBRI-OS is <52. The percentage of cases in the sample that fell into the 'impaired HRQoL' category were 36% for the Mental Component Summary, 38% for the QOLIBRI Total, and 39% for the ...

Health-related quality of life after traumatic brain injury: deriving value sets for the QOLIBRI-OS for Italy, The Netherlands and The United Kingdom

2020

Purpose The Quality of Life after Brain Injury overall scale (QOLIBRI-OS) measures health-related quality of life (HRQoL) after traumatic brain injury (TBI). The aim of this study was to derive value sets for the QOLIBRI-OS in three European countries, which will allow calculation of utility scores for TBI health states. Methods A QOLIBRI-OS value set was derived by using discrete choice experiments (DCEs) and visual analogue scales (VAS) in general population samples from the Netherlands, United Kingdom and Italy. A three-stage procedure was used: (1) A selection of health states, covering the entire spectrum of severity, was defined; (2) General population samples performed the health state valuation task using a web-based survey with three VAS questions and an at random selection of sixteen DCEs; (3) DCEs were analysed using a conditional logistic regression and were then anchored on the VAS data. Utility scores for QOLIBRI-OS health states were generated resulting in estimates for all potential health states. Results The questionnaire was completed by 13,623 respondents. The biggest weight increase for all attributes is seen from "slightly" to "not at all satisfied", resulting in the largest impact on HRQoL. "Not at all satisfied with how brain is working" should receive the greatest weight in utility calculations in all three countries. Conclusion By transforming the QOLIBRI-OS into utility scores, we enabled the application in economic evaluations and in summary measures of population health, which may be used to inform decision-makers on the best interventions and strategies for TBI patients.
