Abstract

PURPOSE: The Visual Analogue Scale applied by an observer (VASobs) is widely used to quantify pain but the evidence to support validity is poor. The aim of this study was to evaluate the psychometric and practical properties of the VASobs used to assess procedural pain in infants and young children. DESIGN AND METHODS: In an observational study, 26 clinicians applied the VASobs independently to video segments of 100 children aged six to 42 months undergoing a procedure to generate pain and distress scores. Each video segment was scored by four randomly selected reviewers. RESULTS: Reliability for pain scores was poor to fair (ICC 0.35 to 0.55) but higher for distress scores (ICC 0.6 to 0.89)..
