Establishing Intra- and Inter-Rater Agreement of the Face, Legs, Activity, Cry, Consolability Scale for Evaluating Pain in Toddlers During Immunization

Abstract

BACKGROUND: The Face, Legs, Activity, Cry, Consolability (FLACC) scale is a five-item tool that was developed to assess postoperative pain in young children. The tool is frequently used as an outcome measure in studies investigating acute procedural pain in young children; however, there are limited published psychometric data in this context.
