At what age can children reliably use the FACES scale?

Children as young as 3 years can point to faces, but reliable self-report requires understanding the concept of pain intensity. Most children achieve reliable use by age 4–5. The scale is validated for ages 3–18 and preferred by children over numerical scales.

Does the smiling face cause overreporting of low pain?

Research shows the smiling face (score 0) can be interpreted positively as 'happy' rather than 'no pain' by some children, potentially underreporting mild pain. The Faces Pain Scale-Revised (FPS-R) uses neutral to grimacing faces without a smile to address this.
