Objective: to perform the cross-cultural adaptation of the SINBAD System Classification for Brazilian Portuguese and analyze its content validity and reliability. Method: clinimetric study, including cross-cultural adaptation of the SINBAD System Classification, used to assess foot ulcers in people with diabetes. Verification of semantic and cultural equivalence and clinical usability using the inter-rater reliability (IRR) index (≥ 0.80); content validity using the Content Validity Ratio (CVR) p < 0.05, and internal consistency using McDonald’s omega (> 0.70). The sample involved nurses, physicians, and people with diabetes-related foot ulcers. Data collection was performed using online forms and in-person clinical evaluation of patients treated at referral services in Goiânia, Jataí, São Paulo, Belo Horizonte, and primary care center in Palmas. Results: fifteen nurses participated in the cognitive debriefing; 20 experts (physicians and nurses) participated in content validation; and 113 patients with 120 diabetes-related foot ulcers participated. Eight items (terms and expressions) from the SINBAD System underwent cross-cultural adaptation. CVR = 0.84 and McDonald’s omega = 0.635 were obtained. Conclusion: the SINBAD system is adapted to Brazilian Portuguese and has satisfactory content validity indices, but it needs investment to achieve greater robustness in terms of reliability and internal consistency.
