Women's pursuit of personal goals in daily life with fibromyalgia: a value-expectancy analysis.

Eighty-nine women with fibromyalgia completed the Life Orientation Test, identified health and social goals, and answered questions from the Goal Systems Assessment Battery (P. Karoly & L. Ruehlman, 1995) about their valuation of, and self-efficiency in attaining, each goal. For 30 days, they responded to palm-top computer interviews about their pain and fatigue and rated their goal effort, goal progress, and pain- and fatigue-related goal barriers. Goal barriers increased and goal efforts and progress decreased on days with greater pain and fatigue; goals valued more highly were pursued more effortfully and successfully; more optimistic individuals were less likely to perceive goal barriers and, on days that were more fatiguing than usual, were less likely to reduce their effort and to retreat from progress in achieving their health goal; and more pessimistic individuals perceived greater goal barriers on days that were less painful than usual.
