The Glasgow Assessment Schedule: Clinical and research assessment of head injury outcome

Abstract

A new rating instrument, the Glasgow Assessment Schedule (GAS), is described for the evaluation of head injury outcome. The instrument, which has been used in samples of head-injured men, provides for a comprehensive assessment, and can distinguish mildly and severely injured patients and rate change over time. Inter-rater reliability and concurrent validity with a global rating scale has been found to be satisfactory. It is expected that the GAS will mainly be of use in clinical and research settings in which longer-term management is envisaged.
