TI  - How much change in the stroke impact scale-16 is important to people who have 
      experienced a stroke?

AB  - BACKGROUND: The Stroke Impact Scale-16 (SIS-16) is used clinically and in 
      research to measure quality of life after stroke. There are no studies that have 
      estimated how much change on the SIS-16 is an important amount of change. The aim 
      of this study was to estimate the minimal clinically important difference (MCID) 
      of the SIS-16. METHOD: SIS-16 scores of participants receiving services at 2 
      outpatient physical therapy clinics who met inclusion and exclusion criteria (n = 
      36) were taken at baseline and discharge. At discharge, participants and their 
      physical therapists rated their perceived amount of recovery on a Global Rating 
      of Change (GROC) scale. Estimated MCID values were calculated for the SIS-16 
      using receiver operating characteristics curves with the GROC as anchors. 
      RESULTS: There was no difference in baseline characteristics between participants 
      who reported important improvement and those who did not. There was a fair 
      relationship between change in SIS-16 scores and participants' (0.41) and 
      physical therapists' (0.38) GROC scores. Change in SIS-16 scores was 
      significantly greater in participants who reported an important amount of change 
      on the GROC scale and those who did not. Estimated MCID of the SIS-16 ranged from 
      9.4 to 14.1 depending on the anchor. CONCLUSION: The estimated MCID values 
      presented in this study provide a way for clinicians to evaluate meaningful 
      change in individual patients and for researchers to evaluate meaningful change 
      between groups.
