Fibromyalgia and women's pursuit of personal goals: a daily process analysis.

For 30 days, 50 women with primary fibromyalgia syndrome reported daily progress and effort toward a health-fitness and a social-interpersonal goal and the extent to which their pain and fatigue hindered their accomplishment. They also carried palmtop computers to assess their sleep and their pain, fatigue, and positive and negative mood throughout the day. Analyses of the person-day data set showed that on days during which pain or fatigue increased from morning to evening, participants perceived their goal progress to be more attenuated by pain and fatigue. Unrestorative sleep the night before predicted the following day's effort and progress toward accomplishing health-fitness goals, but not social-interpersonal goals. Finally, participants who reported more progress toward social-interpersonal goals on a given day were more likely to evidence improvements in positive mood across the day, regardless of any changes in pain or fatigue that day.
