Reliability of the color analog scale: repeatability of scores in traumatic and nontraumatic injuries.
OBJECTIVES The objective was to assess in a pediatric emergency department ( ED ) the reliability of the color analog scale ( CAS ) for acute pain assessment , overall and between traumatic and nontraumatic pain etiology . METHODS This was a prospect i ve study of children aged 5 to 16 years in the ED of a children 's hospital who had a complaint of pain . The CAS was administered to the patient at admission and at 30 minutes . To evaluate repeatability , a second measurement was obtained 1 minute following each assessment . This assumed there would be no substantial change in pain intensity within 1 minute . The authors used the intraclass correlation coefficient ( ICC ) to evaluate the repeatability of 1-minute interval measurements . RESULTS A total of 170 patients were enrolled . The origin of pain was traumatic in 81 cases ( 48 % ) . Regardless of pain etiology , the  CAS scores were highly repeatable ( r = 0.97 , 95 % confidence interval [ CI ] = 0.95 to 0.98 ) . CONCLUSIONS The color analog scale is both a valid and a reliable self-reporting tool in the assessment of acute pain in children
