Abstract
to perform the cross-cultural adaptation of the SINBAD System Classification for Brazilian Portuguese and analyze its content validity and reliability. 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. 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. 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.
