This study looked at 33 patients with widespread pain to understand how different diagnostic labels (fibromyalgia, chronic fatigue syndrome, and bodily distress syndrome) overlap and apply to the same people. Researchers also tested whether a patient-created quality-of-life survey could capture things that standard questionnaires miss. They found that most patients had very low quality of life scores, and that the newer diagnostic criteria for fibromyalgia work better together than older versions.
