Their main limitation is underestimation of pain in the days following an intervention. Although relevant, facial expression is not used in daily clinical practice. This prospective study aimed to assess the validity and reliability of the Facial Action Summary Score (FASS), a five\u2010item scale, to assess postoperative pain until hospital discharge in children &lt;7\u00a0years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Assessments of pain and anxiety of 123 children using FASS and validated scales were used to study the psychometric validity of the FASS in clinical practice.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The content validity was previously investigated in a development study. The internal validity of the FASS was high with excellent reliability (intraclass coefficient\u00a0=\u00a00.94) and a high Cronbach \u03b1 (0.89). Convergent validity with pain scales (FLACC [Face, Legs, Activity, Cry, Consoling] and FPS\u2010R [Faces Pain Scale \u2013 Revised]) was high (<jats:italic>r<\/jats:italic>\u00a0&gt;\u00a00.8). Sensitivity to change was verified by a significant decrease in the score after rescue analgesia. For a threshold of 2\/5, the FASS shows excellent specificity (97%) and sensitivity (82%). The low number of false negatives is the main strength of this tool.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This work highlights the interest in using facial expression in daily clinical practice to manage postoperative pain.
