Cross-cultural adaptation of the Satisfaction and Recovery Index among Japanese people with musculoskeletal disorders

抄録

[Purpose] The primary aim was to cross-culturally adapt the Satisfaction and Recovery Index (SRI) among Japanese people. The secondary aim was to preliminarily investigate the convergent validity of the SRI with the SF-12v2^® Health Survey among ambulatory patients with musculoskeletal disorders. [Participants and Methods] A provisional Japanese SRI was developed after forward and backward translations and confirmation from its original developer. This study included 30 outpatients diagnosed with musculoskeletal disorders at an orthopedic clinic in Japan. All participants underwent the SF-12v2^® Health Survey and the provisional Japanese SRI. They were then asked to provide comments about the provisional Japanese SRI. Pearson’s r was calculated to examine the convergent validity between the SF-12v2^® Health Survey scores and the provisional Japanese SRI scores. [Results] The provisional Japanese SRI was accepted as the final version due to no serious concerns raised by the participants. Only the mental component scores of the SF-12v2^® Health Survey had a statistically significant correlation (r=0.45), indicating partial evidence of the convergent validity of the provisional Japanese SRI. [Conclusion] This study developed the Japanese SRI with preliminary validity evidence among ambulatory patients with musculoskeletal disorders.
