This study aimed to adapt a Spanish translation of the Oswestry Disability Index (ODI) into a cross-cultural version for the Mexican population. The objectives were to verify the validity and reliability of the adapted ODI and to compare pain perception between patients with and without obesity. We included 102 patients with low back pain from two neurosurgery departments in Mexico. The ODI questionnaire was translated and culturally adapted. Validity and construct were evaluated using exploratory factor analysis, and the external convergent validity was assessed by correlating ODI scores with pain intensity, age, and obesity. Test-retest reliability was calculated using the intraclass correlation coefficient, and confirmatory analysis was employed to validate the factorial structure. Patients with obesity were older and had higher pain scores than patients without obesity. The exploratory analysis of the ODI in Mexican Spanish showed good reliability (Cronbach's alpha of 0.923) and validity (factorial loading range, 0.681 − 0.818). The confirmatory analysis showed almost null or very low discrepancy between the proposed model and the real data. A Spanish translation of ODI was cross-culturally adapted for the Mexican population. The Mexican version of the ODI showed good reliability and validity in Mexican culture. The Oswestry Disability Index (ODI) is a widely used tool to measure physical disability in daily activities due to low back pain. A Spanish-language version has not been culturally adapted and validated for Mexican habits and lifestyle. This study describes the process of the Spanish ODI translation and cultural adaptation, showing it is a reliable and valid tool for assessing disability in patients with low back pain, with a good factorial structure.
