Objective[edit | edit source]
The Stroke Impact Scale (SIS) is a patient-reported outcome measure that evaluates the biopsychosocial aspects of life after stroke. [1] It is designed by Duncan et al at the University of Kansas Medical Center in 1999, first published as version 2.0.[2] The original 64-item tool was shortened to be 59-item after a Rasch analysis process, creating the current version 3.0.[3]
For patients who are unable to answer, there is a proxy version available called Stroke Impact Scale-16.[4]
Intended Population[edit | edit source]
The tool is intended for post-stroke patients, administered repeatedly over time to track changes.
Method of Use[edit | edit source]
Equipment required: Questionnaire and pen
Time to administer: 15-20 minutes
Instructions: Rate the level of difficulty of completing an item in the past 2 weeks following a 5-point Likert scale:
- 1 = could not do it at all
- 2= very difficult
- 3= somewhat difficult
- 4= a little difficult
- 5= not difficult at all
Domains:
The questionnaire consists of 59 items that assess 8 domains:
- Strength (4 items)
- Hand function (5 items)
- ADL/IADL (10 items)
- Mobility (9 items)
- Communication (7 items)
- Emotion (9 items)
- Memory and thinking (7 items)
- Participation/Role function (8 items)
Scoring:
- Summative scores are generated for each domain, scores ranging from 0-100.
- Formula for each scale:
- Transformed Scale = [(Actual raw score - lowest possible raw score) / Possible raw score range] x 100
