Key result
A proposed motivational framework defines fatigue in chronic pain as an aversive state urging disengagement from effortful behavior when costs exceed benefits.
Conceptualizing fatigue in chronic pain as a motivational state driven by a cost-benefit trade-off provides a novel framework for future research and targeted behavioral interventions.
May guide motivational interventions for fatigue in chronic pain; leaves open prospective validation before clinical adoption.
