Study design: Cross-sectional validation study. Objectives: To develop and validate a self-report version of the Spinal Cord Independence Measure (SCIM III). Setting: Two SCI rehabilitation facilities in Switzerland. Methods: SCIM III comprises 19 questions on daily tasks with a total score between 0 and 100 and subscales for 'self-care', 'respiration & sphincter management' and 'mobility'. A self-report version (SCIM-SR) was developed by expert discussions and pretests in individuals with spinal cord injury (SCI) using a German translation. A convenience sample of 99 inpatients with SCI was recruited. SCIM-SR data were analyzed together with SCIM III data obtained from attending health professionals. Results: High correlations between SCIM III and SCIM-SR were observed. Pearson's r for the total score was 0.87 (95% confidence interval (
INTRODUCTIONThe Spinal Cord Independence Measure (SCIM), which was first published in 1997, 1 has become a widely used instrument to measure functioning in activities of daily living in persons with spinal cord injury (SCI). 2 Its main advantages over other instruments used for functional assessment in rehabilitation medicine are its sensitivity to changes in performance of tasks that are relevant for SCI patients, and the fact that it measures not only the burden of care, but also achievements, which have medical, psychological or social relevance for the SCI patient. The third version of the instrument, SCIM III, has been tested for validity and reliability in multicenter studies with satisfying psychometric properties. [3][4][5] SCIM III comprises items on 19 daily tasks grouped into three subscales. Item scores are weighted according to their clinical relevance and are graded for increasing difficulty, that is, requiring higher ability of the person with SCI. Each item has between 2 and 9 grades. The total SCIM III score ranges between 0 and 100, higher scores reflecting higher levels of performance or independence of a person. 3 The three subscales assess the areas of 'self-care' (six items, range 0-20), 'respiration & sphincter management' (four items, range 0-40) and 'mobility' (nine items, range 0-40).SCIM III is scored in observation of persons with SCI by health professionals. Ideally, each subscale is scored by clinical staff experienced in the assessment of the activities covered by the subscale. Such observations are time consuming and mainly applicable in inpatient settings. 6 In the outpatient setting, SCIM III data were collected by a single rater or in interviews previously, although with slightly decreased precision. 7,8 For research purposes, SCIM data are obtained by interview as part of the regular follow-up of large international studies, such as the European Multicenter Study about Spinal Cord Injury (EMSCI). 9 Studies conducted in the SCI community usually rely on selfadministered questionnaires for data collection. This method requires comparatively few resources, provides fast data collection and is applicable independent of the setting. 6,10 Using...
