Ability of 3-to 5-year-old children to use simplified self-report measures of pain intensity

Little is known about self-report pain intensity scales best suited for young children. We tested the ability of preschool children to use two simplified scales (concrete ordinal and faces). Three- to 5-year-olds (n= 123) were asked to make binary discriminations ('less' vs 'more' pain) between response options using the Simplified Faces Pain Scale and Simplified Concrete Ordinal Scale and to complete a seriation task. Eighty participants were also asked to use the Simplified Concrete Ordinal Scale, with modified verbal anchors, to rate the loudness of tones and to assess practice effects. Binary discrimination accuracy and seriation ability improved with age. When using the Simplified Concrete Ordinal Scale to rate the loudness of tones, even the 3-year-olds performed significantly better than chance, and performance was better in 4- and 5-year-olds. Little evidence supported the ability of 3-year-olds to use either of the simplified tools in the pain context. The 4-year-olds demonstrated greater accuracy in using the Simplified Concrete Ordinal Scale than the Simplified Faces Pain Scale, suggesting that the Simplified Concrete Ordinal Scale may be more appropriate for this age group.

Automated summary

This study examined the ability of preschool children to use two simplified pain intensity scales and found that accuracy in binary discrimination and seriation ability improved with age. Three-year-olds showed poor performance in using the simplified tools, while four-year-olds displayed greater accuracy with the Simplified Concrete Ordinal Scale compared to the Simplified Faces Pain Scale.
