Measurement Characteristics and Clinical Utility of the Stroke Impact Scale

      The Stroke Impact Scale (SIS) is a multidimensional, stroke-specific, self-report outcome measure. There are 59 items in 8 domains including strength, hand function, activities of daily living/instrumental activities of daily living, mobility, communication, emotion, memory and thinking, and participation/role function. Patients use a 5-point Likert scale to rate the level of difficulty they experience during each activity. Summative scores are generated for each domain. An additional item rates stroke recovery on a scale from 0 to 100. Adequate to excellent reliability has been reported.1,2 Normative data are available. Responsiveness data (minimal detectable change and minimal clinically important difference) have been reported for some domains of the measure.3 The test can be completed in 15 to 20 minutes. Mail, telephone, and proxy administration have been validated.1,4 A 16-item version measure (SIS-16) captures physical performance during daily activities.5 The cost of the measure for nonprofit users is free.
      A full review of the SIS as well as reviews of nearly 200 other instruments can be found at www.rehabmeasures.org.
