脑损伤后生活质量（QOLIBRI）量表是最近开发的一种工具，它提供了一个典型的脑损伤影响领域的健康相关生活质量（HRQoL）的概况。然而，就全球评估而言，最好有一个简要的概括衡量标准。本研究探讨了6项QOLIBRI总体量表（QOLIBRI-OS），并考虑它是否可以提供一个指标的HRQoL创伤性脑损伤（TBI）后，方法的性质的QOLIBRI-OS进行了研究，在一个样本的792名参与者与TBI招募中心在9个国家，涵盖6种语言。在德国招募的153名参与者中进行了结构效度的检验，这些参与者被评估了两个相关的简要生活质量测量，生活满意度量表和生活质量视觉辅助量表（Cronbach's a 0.86，重测信度=0.81），并且在具有较高和较低认知表现的参与者中相似。因子分析表明，量表是单维度的。Rasch分析也表明与该模型的拟合令人满意。QOLIBRI-OS与QOLIBRI量表总分高度相关（r=0.87）。在QOLIBRI-OS和扩展格拉斯哥结局量表、简表-36和医院焦虑和抑郁量表之间发现中度至强相关性（r=0.54至-0.76）。QOLIBRI-OS在TBI组显示了良好的结构效度。结论QOLIBRI-OS评估了类似的结构QOLIBRI总分，可以作为一个简短的指标HRQoL TBI。
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 a 0.86, test-retest reliability =0.81) 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 (r=0.87). Moderate to strong relationships were found among the QOLIBRI-OS and the Extended Glasgow Outcome Scale, Short-Form-36, and Hospital Anxiety and Depression scale (r=0.54 to -0.76). 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.
