Validity and reliability of two pain assessment tools in Brazilian children and adolescents.

Aims: The aim of this research is to examine the validity and reliability of the Brazilian version of the Revised Faces Pain Scale and the Face, Legs, Activity, Cry, Consolability scale.

Background: Several self-report and behavioural pain tools have been shown to have good psychometric properties for the evaluation of pain in children and adolescents. This study was designed to analyse the correlation between two pain scales in school-age children and adolescents.

Cross-cultural adaptation and translation of two pain assessment tools in children and adolescents.

Objective: To translate, back-translate and cross-culturally adapt the content of the FLACC (Face, Legs, Activity, Cry, Consolability) and Faces Pain Scale-Revised (FPS-R) scales for the evaluation of pain in Brazilian young students and adolescents.

Methods: The original scales in English were translated into Brazilian Portuguese. Scales thus obtained were back translated and reviewed.
