Abstract
Fibromyalgia is a chronic condition involving widespread pain, fatigue, and cognitive dysfunction. Evidence-based interventions for fibromyalgia, such as education and exercise, often require prolonged, cognitive and/or physical effort, involving immediate costs (effort) for delayed benefits (improved pain/function). Initiation of, and adherence to, these interventions is often difficult, which may reflect pain-related alterations in an individual’s attitudes towards effortful and delayed rewards. Here we explored whether individuals with fibromyalgia differed from age- and sex-matched pain-free controls in such attitudes. In cross-sectional Study 1, individuals with fibromyalgia (N=19) and controls (N=19) completed tasks offering real rewards for performing actual physical or cognitive effort or enduring real delays. Despite individualizing task difficulty to each participant’s unique capacity, those with fibromyalgia required higher incentives to engage in the physical effort task (treadmill walking), especially at higher effort intensities (OR=1.077, 95%CI [1.003, 1.156]), but showed no differences in the cognitive effort task, indicating no general motivation deficit but rather a shift in attitudes toward physical exertion. Additionally, participants with fibromyalgia showed a greater willingness to wait for rewards (OR=0.726, 95%CI [0.533, 0.990]), particularly at lower reward levels, suggesting an increased motivation driven by rewards. Study 2, conducted online (N=43 fibromyalgia, N=139 controls), replicated the findings regarding physical effort (t=3.36, 95%CI [0.08, 0.29]), reinforcing that fibromyalgia does not involve a broad motivational deficits. Instead, we found specific changes in physical effort discounting and indications of heightened sensitivity to rewards in delay discounting. These insights may help inform tailored intervention strategies for individuals with fibromyalgia.
Perspective
This article identifies altered attitudes toward physical effort and delayed rewards in individuals with fibromyalgia. These findings suggest that difficulties with treatment adherence may stem from over-protective physical effort-related decision-making rather than low motivation, offering a potential target for personalized education and intervention strategies in clinical care.
期刊介绍:
The Journal of Pain publishes original articles related to all aspects of pain, including clinical and basic research, patient care, education, and health policy. Articles selected for publication in the Journal are most commonly reports of original clinical research or reports of original basic research. In addition, invited critical reviews, including meta analyses of drugs for pain management, invited commentaries on reviews, and exceptional case studies are published in the Journal. The mission of the Journal is to improve the care of patients in pain by providing a forum for clinical researchers, basic scientists, clinicians, and other health professionals to publish original research.
