Faces Pain Scale - Revised
The assessment of pain in children is an important means to guide diagnosis and evaluate treatment strategies. A child’s self-report of pain is considered most reliable, and the Faces Pain Scale - Revised (FPS-R) meets the unique assessment needs and responses of children. Recommended for ages 4-16, this pain scale is easy to administer and requires no special equipment except for photocopied faces. Learn how to use this tool for pediatric pain assessment.
