Methods: After receiving authorization by the main author, the State Behavioral Scale was adapted according to the following steps: translation of the original version into Portuguese; synthesis of the Portuguese versions; evaluation by a committee of judges; reverse translation by native speakers of the source language; synthesis of retroversions; pretest; and evaluation of psychometric quality. Results: The adapted scale was administered to 20 patients by four evaluators, who performed daily evaluations in pairs simultaneously and independently. The intraclass correlation coefficient was 0.939 (p < 0.001) for the State Behavioral Scale and 0.976 (p < 0.001) for the COMFORT-B scale. The two scales were strongly correlated, with Spearman coefficients ranging from 0.884 to 0.908 (p < 0.001). In the study sample, most children (n = 43 observations; 48.9%) had scores of -1 (responsive to light touch or voice) or 0 (awake and able to calm down), which corresponded to light sedation. Conclusion: The translated and adapted version of the State Behavioral Scale showed high interrater agreement and high correlation with the COMFORT-B scale. The application of the scale showed an adequate level of sedation in most patients.enState Behavioral ScalePediatric intensive care unitsArtificial respirationCross-cultural adaptationSurveys and questionnairesBrazilArticlehttps://doi.org/10.62675/2965-2774.202501839Psicologia e SaúdeDimensões psicossociais do cuidado em contextos clínicos e de Políticas Públicasfalse
