Translation, cross-cultural adaptation, and validation of the patient-rated wrist evaluation into Spanish (Mexico)

This study aimed to translate, cross-culturally adapt, and validate the psychometric properties of the Patient-Rated Wrist Evaluation (PRWE) for use in Mexican Spanish-speaking patients (PRWE-MX) with distal radius fractures.

The translation and cross-cultural adaptation followed international guidelines. Reliability was assessed using test-retest intraclass correlation coefficients (ICC) and internal consistency (Cronbach's alpha). Validity was analyzed by correlating PRWE-MX scores with the QuickDASH and EQ-5D instruments. Floor and ceiling effects were also examined.

A total of 76 patients participated. The PRWE-MX demonstrated excellent reliability, with ICC values of 0.95 (total score), 0.92 (pain), and 0.94 (function). Cronbach's alpha exceeded 0.94 for all subscales. Construct validity was supported by strong correlations with the QuickDASH (r = 0.772, 8 weeks; r = 0.864, 12 weeks) and moderate correlations with the EQ-5D (r = -0.562, 8 weeks; r = -0.427, 12 weeks). Floor and ceiling effects were minimal.

The PRWE-MX is a reliable and valid tool for evaluating wrist function and pain in Spanish-speaking patients in Mexico. Its strong psychometric properties support its use in both clinical and research settings.
