ABSTRACT The consequences of traumatic brain injury (TBI) for health-related quality of life (HRQoL) are poorly investigated, and a TBI-specific instrument has not previously been available. The cross-cultural development of a new measure to assess HRQoL after TBI is described here. An international TBI Task Force derived a conceptual model from previous work, constructed an initial item bank of 148 items, and then reduced the item set through two successive multicenter validation studies. The first study, with eight language versions of the QOLIBRI, recruited 1528 participants with TBI, and the second with six language versions, recruited 921 participants. The data from 795 participants from the second study who had complete Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) data were used to finalize the instrument. The final version of the QOLIBRI consists of 37 items in six scales (see Appendix ). Satisfaction is assessed in the areas of "Cognition," "Self," "Daily Life and Autonomy," and "Social Relationships," and feeling bothered by "Emotions," and "Physical Problems." The QOLIBRI scales meet standard psychometric criteria (internal consistency, alpha = 0.75-0.89, test-retest reliability, r(tt) = 0.78-0.85). Test-retest reliability (r(tt) = 0.68-0.87) as well as internal consistency (alpha = 0.81-0.91) were also good in a subgroup of participants with lower cognitive performance. Although there is one strong HRQoL factor, a six-scale structure explaining additional variance was validated by exploratory and confirmatory factor analyses, and with Rasch modeling. The QOLIBRI is a new cross-culturally developed instrument for assessing HRQoL after TBI that fulfills standard psychometric criteria. It is potentially useful for clinicians and researchers conducting clinical trials, for assessing the impact of rehabilitation or other interventions, and for carrying out epidemiological surveys.

    • "The Quality of Life after Brain Injury (QOLIBRI) assessment has been developed as a descriptive system for HRQoL in brain injury patients. QOLIBRI is a patient-reported outcome instrument consisting of a 37 item scale with six subscales covering the areas of physical condition, cognition, emotion, function in daily life, personal and social life, and current situation and future prospects [6] [7]. In initial studies of traumatic brain injury patients in different countries, QOLIBRI was found to be valid and reliable [8]. "

    ABSTRACT: The Quality of Life after Brain Injury Overall Scale (QOLIBRI-OS) is a recently developed instrument that provides a brief summary measure of health-related quality of life (HRQoL) in domains typically affected by brain injury. This 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 1year 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 1year 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.

    ABSTRACT: The problems connected with the intensive noise oscillation excitation in the millimeter wave band are studied. With this aim in mind, the O-type backward wave oscillators, operating in the chaotic oscillation regime, are proposed. The advantages of the method suggested are the high efficiency, universal power spectrum and the feasibility of electronic tuning of the noise oscillation frequency. Low voltage packaged noise sources, operating over the 30 to 60 GHz band, make possible output power of 8-25 W and 4 W respectively and a 3-dB power spectrum width of more than 300 MHz

    ABSTRACT: The Glasgow Outcome Scale (GOS) is the most widely used outcome measure after traumatic brain injury, but it is increasingly recognized to have important limitations. It is proposed that shortcomings of the GOS can be addressed by adopting a standard format for the interview used to assign outcome. A set of guidelines are outlined that are directed at the main problems encountered in applying the GOS. The guidelines cover the general principles underlying the use of the GOS and common practical problems of applying the scale. Structured interview schedules are described for both the five-point GOS and an extended eight-point GOS (GOSE). An interrater reliability study of the structured interviews for the GOS and GOSE yielded weighted kappa values of 0.89 and 0.85, respectively. It is concluded that assessment of the GOS using a standard format with a written protocol is practical and reliable.
