Spanish translation and cross-language validation of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form.

Background: The American Shoulder and Elbow Surgeons (ASES) Standardized Shoulder Assessment Form is one of the most frequently used outcomes score for shoulder pathology. The patient report section of the ASES questionnaire (p-ASES) is easy to complete, can be quickly administered, and is applicable to a wide range of shoulder pathologies, yet a validated Spanish translation of this questionnaire does not currently exist for diverse Spanish-speaking populations. The purpose of this study was to translate and culturally adapt the patient report section of the ASES to Spanish and to assess its validity and reliability among a culturally diverse group of Spanish-speaking patients, typically seen in the United States.
