Sound psychometric properties of the Swedish version of the Spinal Cord Independence Measure Self-Report

OBJECTIVE: To describe data completeness, targeting and reliability of the Swedish version of the Spinal Cord Independence Measure Self-Report (s-SCIM-SR). DESIGN: Translation and reliability study. SUBJECTS: Programme participants (n = 48) and peer mentors (n = 42) with spinal cord injury enrolled in the INTERnational Project for the Evaluation of "activE Rehabilitation" (inter-PEER). METHODS: The translation process was based on guidelines/recommendations, and involved expert competence, including consumers. The s-SCIM-SR was distributed online, once for programme participants and twice for peer mentors. RESULTS: Sixty-nine individuals (77%) obtained a total score. Most missing data were found in the items Respiration and Using the toilet. Cronbach's alpha for the full scale was 0.89, for Self-care 0.92, for Respiration and sphincter management 0.37 and for Mobility 0.86. The intraclass correlation coefficient was excellent for all subscales and the full scale. Measures of variability showed high sensitivity to changes and Bland Altman analyses revealed no systematic changes between evaluation points. CONCLUSION: These results support the data completeness, targeting and reliability of the Swedish version of the SCIM-SR. However, some problems were found in the subscale Respiration and sphincter management. The s-SCIM-SR can be considered psychometrically sound and suitable to assess physical independence among persons with spinal cord injury in Swedish community settings
