Abstract

The aims of this descriptive study were to evaluate the construct validity by known group technique and convergent validity of multitrait-multimethod technique and to evaluate and compare the reliability of the COMFORT - B scale and the modified FLACC scale. Thirty two ventilated sedated children aged 1 month to 4 years were included in this study. Two trained nurses who passed the acceptable value of the inter rater reliability (ICC of COMFORT - B scale and modified FLACC scale = 98 and ,94 respectively), observed each child from 10 VDOs simultaneously and assessed pain score using both scales before and after endotracheal closed system suctioning. Each period of observations was repeated three times. The personal data were analyzed by using descriptive statistic. The construct validity of known group technique data were analyzed by using paired-sample-t test. The convergent validity of multitrait-multimethod technique data were analyzed by Pearson's product moment correlation. Inter rater reliability was assessed using the intra-class correlation coefficient (ICC). The results revealed that the COMFORT - B and the modified FLACC scale showed construct validity as both scales discriminated pain before and after suctioning (t = -30.98, p < ,001 and t = -28.06, p<.001 respectively) and also could measure pain because both scales were corelated (before suctioning r= .23, P = 024 after suctioning r = .73, p = 000). In addition, the inter rater reliability of both scales was equally excellent (ICC = 98). The results showed that both scales, the COMFORT - B scale and the modified FLACC scale, have construct validity and reliability properties in assessing acute pain. This information can provide evidence base for nurses to choose the most appropriate pain scale to assess pain in children.
