Translation into Greek and initial validity and reliability testing of a modified version of the SCIM III, in both English and Greek, for self-use

Abstract

© 2015 The Author(s). Purpose: To translate and culturally adapt the Spinal Cord Injury Measure version III (SCIM III) into Greek (GR-SCIM III). To conduct initial testing of psychometric properties of both measures by self-report. Method: Forward–backward translation was conducted to produce the GR-SCIM III. Participants completed the English or Greek versions in 2008–2009. Both versions were examined for multidimensionality, internal consistency and concurrent/criterion validity with the EQ-5D. Results: Forty-five Greek adults with spinal cord injury (SCI) (23 males), mean age 61 (SD17) years; mean time since injury 11 (SD9) years, completed the GR-SCIM III. One hundred and seventy four English-speaking adults with SCI (111 males), mean age 47 (SD12) years; mean time since injury 12 (SD11) years, completed the SCIM III. Unidimensionality was confirmed for both versions. Internal consistency was acceptable (α = 0.78 for both). Validity was strong for the “self-care” subscale (GR-SCIM III ρ = −0.78, SCIM III ρ = −0.75) and moderate for the “mobility” subscale (GR-SCIM III ρ = −0.58, SCIM III ρ = −0.45). Conclusions: This has been the first function scale translated and validated in Greek for people with SCI. Both the GR-SCIM III and SCIM III are reliable for use by self-report. More studies are needed to further examine their psychometric properties and compare with observation or interview.Implications for Rehabilitation • The Greek version of the Spinal Cord Independence Measure version III (SCIM) is valid and reliable for self-report. Further testing is needed to assess psychometric qualities not assessed in the present study. • Researchers and therapists in Greece can use a specific measure to assess functional independence in people with Spinal Cord Injury (SCI). • Consideration needs to be given to the participants’ type of injury, which may affect the results of SCIM III.
