quote: The overall objective of the third meeting was to maintain the momentum of the International Collaborative Group and continue the work to more precisely define CFS. The specific aim was to discuss how standard instruments measuring the major symptom domains of CFS could be used internationally in clinical research settings. During the meeting, three working groups sought to develop strategies to address the following issues:-A means by which standard instruments can be uniformly applied in different clinical and cultural settings. -Specific standard instruments that would optimally measure fatigue severity, disability, cognition, sleep, other symptoms, and psychiatric comorbidity and could be uniformly used in international clinical settings.-Analytic procedures that would identify symptom dimensions among persons with CFS and other unexplained chronically fatiguing illnesses in international clinical research settings and would define the variability of symptom dimensions manifest by different patient populations. This group also discussed study designs necessary to accomplish analysis.
