Our clinical observations and initial pilot work suggest that factors common among other insomnia subtypes such as conditioned bedtime arousal, erratic sleep/wake scheduling, and spending too much time in bed likely perpetuate the sleep problems of these medication-refractory FM patients. Over the past decade, we have developed, refined, and repeatedly tested a cognitive-behavioral therapy (CBT) that has proven effective for reducing sleep disturbances perpetuated by such underlying cognitive/behavioral mechanisms. The major objectives of this project are to conduct a prospective randomized clinical trial to confirm these preliminary findings and to determine the efficacy of CBT insomnia treatment for interrupting the disturbed nocturnal sleep and daytime pain, fatigue, and distress symptom complex that defines FM.
