Reliability and validity of the Korean version of the Short Musculoskeletal Function Assessment questionnaire for patients with musculoskeletal disorder

Abstract

[Purpose] The purpose of this study was to establish the reliability and validity of the Short Musculoskeletal Function Assessment questionnaire, which was translated into Korean, for patients with musculoskeletal disorder. [Subjects and Methods] Fifty-five subjects (26 males and 29 females) with musculoskeletal diseases participated in the study. The Short Musculoskeletal Function Assessment questionnaire focuses on a limited range of physical functions and includes a dysfunction index and a bother index. Reliability was determined using the intraclass correlation coefficient, and validity was examined by correlating short musculoskeletal function assessment scores with the 36-item Short-Form Health Survey (SF-36) score. [Results] The reliability was 0.97 for the dysfunction index and 0.94 for the bother index. Validity was established by comparison with Korean version of the SF-36. [Conclusion] This study demonstrated that the Korean version of the Short Musculoskeletal Function Assessment questionnaire is a reliable and valid instrument for the assessment of musculoskeletal disorders.

Structural Validity of the Short Musculoskeletal Function Assessment in Patients With Injuries

“…Later, the SMFA was translated and cross-culturally adapted into multiple languages. [9][10][11][12][13][14][15][16] In some cross-cultural validation studies, it was argued that the SMFA may be interpreted by 3, 14,15 4 10,11 or 6 9 subscales instead of the original 2. 8 The validity of the different configurations of subscales (ie, structural validity) has rarely been studied, resulting in inconsistency about the number and nature of the latent constructs that are evaluated with the SMFA.…”

“…The originally (American) English SMFA has been translated and cross-culturally adapted into Chinese, Danish, Dutch, German, Korean, Portuguese, Spanish, and Swedish. [9][10][11][12][13][14][15][16]…”
