Converting three general-cognitive function scales into persian and assessment of their validity and reliability.

Objectives: Glasgow Outcome Scale Extended (GOSE), Galveston Amnesia and orientation Test (GOAT) and Disability Rating Scale (DRS) are three popular outcome measure tools used principally in traumatic brain injury (TBI) patients. We conducted this study to provide a Farsi version of these outcome scales for use in Iran.

Methods: Following a comprehensive literature review, Farsi transcripts were prepared by "forward-backward" translation and reviewed by subject experts.
