The purpose of this study was to examine the convergent validity of the Pain Sensory Tool with the Poker Chip Tool. Both tools were used to assess children's pain intensity (ages 5 to 14 years). A total of 104 hospitalized Taiwanese children with acute pain were asked to participate in this study. ⋯ This raises concerns about the validity of the PST for five-year-old children. It is not clear whether these five-year-old children were outliers or whether the PST is difficult for younger children. The authors suggested duplicating this study and specifying the five-year-old age group for the validity test.
