Crellin DJ, Harrison D, Santamaria N, et al. - Researchers aimed at comparing the psychometric data and feasibility and clinical utility of the Face Legs, Activity, Cry and Consolability scale (FLACC), the Modified Behavioral Pain Scale (MBPS) and the Visual Analogue Scale for observers (VASobs), which are employed to assess procedural pain in infants and young children. Assessment of videorecorded segments of 100 infants and young children who underwent a painful and/or distressing procedure in the emergency department was done by 26 clinicians using the FLACC scale, the MBPS and the VASobs pain and VASobs distress. Study data supported the reliability and sensitivity of the FLACC and MBPS however, concerns were raised regarding the capacity of these scales to differentiate between pain- and non-pain-related distress. They do not recommend using VASobs. Despite its limitations, they suggest the FLACC scale to be better suited relative to other scales for procedural pain measurement.
