Objective: To adapt and validate The Humpty Dumpty Scale for Brazilian culture. Methods: Methodological study that followed the steps of translation, synthesis, back-translation, evaluation by specialists, pre-test and evaluation by the author of the original instrument for the cross-cultural adaptation. A total of 103 children/adolescents admitted to a public hospital in the countryside of the state of Sao Paulo were selected. We used a characterization form, The Humpty Dumpty Scale and the Pediatric Patient Classification Instrument, which was used to assess construct validity, with Spearman’s correlation coefficient. Interobserver reliability was assessed using the Intraclass Correlation Coefficient and the Kappa coefficient. Results: The committee of 12 experts evaluated the equivalence, clarity and relevance of the items and after three rounds, the percentage of 100% agreement was reached. The reformulations made the items more understandable and, after the author’s evaluation, the final version of the instrument was obtained. Positive and significant correlations were found between The Humpty Dumpty Scale and the Patient (r=0.5184; p<0.0001) and Therapeutic Procedures (r=0.2143; p<0.0332) domains of the patient classification instrument. With the Family domain (r=0.0676; p=0.5060), no significant relationships were achieved. Satisfactory evidence of reliability (Intraclass Correlation Coefficient of 0.93 and Kappa coefficient of 0.80) was observed. Conclusion: The Humpty Dumpty Scale was cross-culturally adapted and is now called (in Portuguese) the Ferramenta de Avaliação de Risco de Quedas - Escala Humpty Dumpty. It demonstrated satisfactory evidence of validity and reliability to assess the risk of falling in children and adolescents in the Brazilian context.
