The core questionnaire, the QLQ-C30, is the product of more than a decade of collaborative research. Following its general release in 1993, the QLQ-C30 has been used in a wide range of cancer clinical trials, by a large number of research groups; it has additionally been used in various other, non-trial studies.  \nThis manual contains scoring procedures for the QLQ-C30 versions 1.0, (+3), 2.0 and 3.0; it also contains summary information about supplementary modules.  \nAll publications relating to the QLQ should use the scoring procedures  \ndescribed in this manual.  \nThis manual will be updated at regular intervals, to reflect future changes to the QLQ and to incorporate new supplementary modules.  \nBackground  \nThe EORTC  \nThe European Organisation for Research and Treatment of Cancer (EORTC) was founded in 1962, as an international non-profit organisation. The aims of the EORTC are to conduct, develop, coordinate and stimulate cancer research in Europe by multidisciplinary groups of oncologists and basic scientists. Research is accomplished mainly through the execution of large, prospective, randomised, multicentre, cancer clinical trials.  \nThe EORTC Central Office Data Center, created in 1974, is concerned with all aspects of phase II and phase III cancer clinical trials, from their design to the publication of the final results. Since its inception, over 80,000 patients have been entered in trials handled by the EORTC Data Center. In 1980, the EORTC created the Quality of Life Group, which in 1986 initiated a research programme to develop an integrated, modular approach for evaluating the QoL of patients participating in cancer clinical trials. This led to the development of the EORTC QLQ-C30, a quality of life instrument for cancer patients. To date, more than 2200 studies using the QLQ-C30 have been registered.  \nEORTC QLQ-C36  \nA first generation core questionnaire, the EORTC QLQ-C36, was developed in 1987 . This 36-item questionnaire was designed to be (1) cancer specific, (2) multidimensional in structure, (3) appropriate for self-administration (i.e. brief and easy to complete), and (4) applicable across a range of cultural settings. Detailed results of the international field-testing of the EORTC QLQ-C36 have been reported (Aaronson et al. , 1991) . While the overall psychometric results were promising, they also pointed to some areas in which the questionnaire could benefit from further development. Most of the revision involved only minor changes in the wording of items. A few items were found to be non-informative, and were discarded. The only scale requiring substantial revision, because of inadequate reliability, was the eight-item emotional functioning scale. In the next generation of the instrument, this scale was substituted by a four-item emotional functioning scale that had been used previously in EORTC clinical trials.  \nEORTC QLQ-C30 version 1.0  \nA secon","cbCait8xopPQMbzM","https://ap.wps.com/l/cbCait8xopPQMbzM","pdf",335346,78,"English","# Introduction\n## The EORTC quality of life questionnaire (QLQ)\n# Background\n## The EORTC\n## EORTC QLQ-C36\n## EORTC QLQ-C30 version 1.0\n## EORTC QLQ-C30 (+3)\n## EORTC QLQ-C30 version 2.0","[{\"question\":\"What is the purpose of the EORTC QLQ-C30 Scoring Manual?\",\"answer\":\"It provides scoring procedures for the EORTC QLQ-C30 versions (1.0, (+3), 2.0, 3.0) and includes summary information about supplementary modules used with the questionnaire.\"},{\"question\":\"How is the EORTC QLQ-C30 used in research?\",\"answer\":\"The manual describes the QLQ-C30 as an integrated system for assessing health-related quality of life in cancer patients participating in international clinical trials, and it notes use beyond trial settings.\"},{\"question\":\"What key background information does the manual include?\",\"answer\":\"It includes background on the EORTC organization and the evolution of the questionnaire, including the development from EORTC QLQ-C36 to QLQ-C30 versions 1.0 and (+3), and the rationale for revisions and scale changes.\"}]","EORTC QLQ-C30 Scoring Manual - Third edition - 2001 | PDF",1790329078,197]
