Postoperative self-report of pain in children: interscale agreement, response to analgesic, and preference for a faces scale and a visual analogue scale.
OBJECTIVE To augment available validation data for the Faces Pain Scale - Revised ( FPS-R ) and to assess interscale agreement and preference in comparison with the Coloured Analogue Scale ( CAS ) in pediatric acute pain . METHOD The present prospect i ve , multicentre study included 131 in patients five to 15 years of age ( mean age 8.8 years ; 56 % male ) seen in postoperative recovery . They provided CAS and FPS-R pain scores before and after administration of analgesic medication . Nurses and physicians used the same tools as observational scales . Children and health care providers indicated which scale they preferred . RESULTS  FPS-R scores for the intensity of postoperative pain correlated highly with the corresponding CAS scores in all age groups ( 0.66 < or= r < or= 0.88 ) . There were no significant mean differences in any age group between the scales . Scores on the two scales differed by 210 or less in 81 % to 91 % of children , depending on age . Both scales demonstrated expected changes in postoperative pain following administration of an analgesic . Scores at the upper end point were given by approximately 20 % of children five to six years of age on both scales , compared with 2 % to 9 % in the older age groups . Health care providers ' observational ratings were significantly lower than self-ratings . The FPS-R was preferred over the CAS by most children in all age groups and both sexes . Global satisfaction of the health care providers was similar for both tools . DISCUSSION These results support the use of the FPS-R for most children five years of age or older in the postoperative period . Further research is needed to identify young children , particularly those younger than seven years of age , who have difficulty with self-report tools , and to establish methods for training them in the reliable use of these measures
