A consecutive sample of 800 elderly patients were categorized by age into 3 groups: 61 to 70 years (n = 366), 71 to 80 years (n = 308), and 81 years and over (n = 126). Participants completed 3 Numerical Rating Scales assessing current pain intensity, and both the usual level of pain and average pain distress in the preceding week. The failure rate for scale completion was low for all scales for all age groups, but was significantly higher in the oldest group compared to the youngest group for the scales assessing ..View full abstract
