Introduction to the Extended Glasgow Outcome Scale
The Extended Glasgow Outcome Scale (GOS-E) was developed to address the limitations of the original GOS, including the use of broad categories that are insensitive to change and difficulties with reliability due to lack of a structured interview format. The GOS-E extends the original 5 GOS categories to 8. The 8 categories are: Dead, Vegetative State, Lower Severe Disability, Upper Severe Disability, Lower Moderate Disability, Upper Moderate Disability, Lower Good Recovery, and Upper Good Recovery. A structured interview has been provided to improve reliability of rating. Good interrater reliability and content validity have been demonstrated for the GOS-E (see Properties for further details). Compared to the GOS, the GOS-E has been shown to be more sensitive to change in mild to moderate TBI.
