Short Form Health Survey version-2.0 Turkish (SF-36v2) is an efŞcient outcome parameter in musculoskeletal research

Abstract

Objective: Although the Short Form Health Survey version-2.0 (SF-36v2) is widely used since 2000, theresearchers and clinicians in Turkey have been still using the original version. However, the originalversion includes many deŞciencies and the SF-36v2 was introduced aiming to correct these deŞciencies.The purpose of this study is to indicate differences between SF-36 and SF-36v2 and the present crosscultural adaptation, reliability and validity of the SF-36v2.Patients and methods: The SF-36v2 was cross culturally adapted to Turkish and the measurementproperties of the Turkish version of the SF-36v2 were tested in 50 patients (19 males; mean± SD age:36.9± 14.6 years; range: 16e65 years, BMI; 24.1 ± 4.6) with a variety of musculoskeletal pathologies.Intraclass correlation coefŞcients (ICC) were used to estimate the test-retest reliability. Construct validitywas analyzed with SF-36v2 and EuroQol Group (EQ-5D). The distribution of ceiling andfloor effects wasdetermined.Results: During the cross-cultural adaptation process many changes were made. The Turkish SF-36v2subscales showed excellent test-retest reliability which was ranged 0.80 to 0.95. The highest correlation was found between SF-36v2-PCS and SF-36v2-PF (r¼ 0.75), the lowest correlation was found between SF-36v2-PCS and SF-36v2-MH (r¼ 0.05). The correlations between EQ-5D and SF-36v2 subscalesranged from 0.10 (SF-36v2eVT) to 0.46 (SF-36v2 eRE). We observed no ceiling and floor effects.Conclusion: The cultural adaptation of the SF-36v2 was successful. The SF-36v2 has sufŞcient reliabilityand validity to measure a variety of musculoskeletal pathologies for Turkish-speaking individuals.© 2016 Turkish Association of Orthopaedics and Traumatology.
