The purpose of this 3-year study is to use a cognitive-behavioral intervention to facilitate adoption of a wellness lifestyle in people with fibromyalgia. Specifically, we will test the efficacy of a health promotion computer program (Balance Center) used in conjunction with a wearable sensor (SenseWearTM) for developing a wellness lifestyle and improving the quality of life of adults with fibromyalgia. Balance Center software is a health promotion computer program that helps consumers to: (1) establish goals in the areas of physical activity, nutrition, participation in meaningful, productive activities, sleep, stress-reducing activities, and emotional state; (2) monitor progress toward established goals; and, (3) assess the relationship between these areas in one's daily life. In addition, based on consumer input, it offers suggestions for developing a wellness lifestyle. SenseWearTM, provides objective data about activity level and stress level for consumers to use in combination with the self-assessment data provided by the Balance Center.
