Adaptación transcultural y validación del MSK-30 para el sistema de salud de Cuba

Background: Given current evidence highlighting the need to optimize training on musculoskeletal disease, the MSK-30 questionnaire stands as a valid instrument to assess such knowledge. Objective: To translate and adapt the MSK-30 scale to strengthen knowledge about musculoskeletal disease within the Cuban context of primary healthcare. Methods: An instrumental study was conducted, including forward and backward translation from English to Spanish, evaluation by the researchers which modified three items from the original scale to incorporate a focus on prevention aligned with the competencies of family physicians in Cuba, content validation by seven experts using the Content Validity Index, and the assessment of internal consistency (Cronbach's Alpha) and feasibility in a pilot sample of 12 family physicians. Results: An adapted version, the Cuban MSK-30, was developed, including 27 original items and three new items on prevention. Content validity was excellent, with 29 items exceeding a CVI ≥ 0.78. Item 27 was reworked after an initially unfavorable evaluation. The scale demonstrated excellent internal consistency (Cronbach's Alpha = 0.89) and high feasibility, with an average response time of 12 minutes. Conclusions: The study provides a valid, reliable, and culturally adapted tool to assess musculoskeletal knowledge among physicians in Cuba. The adapted version of the MSK-30 is a valuable resource for medical education and research, incorporating the essential preventive focus of primary care.
