Headache
-
Recurrent headache sufferers are often fearful of pain, which disrupts thought processes, interferes with daily activities, and may maintain headache-related disability through avoidance and associated negative reinforcement. ⋯ FOP differentiates migraineurs from those without headache and plays a significant role in primary headache, particularly in headache-related disability. Findings build upon and extend those from previous chronic pain studies and highlight the need for longitudinal and experimental studies to further explore this construct in headache.
