Global Impression Scales

Clinical Global Impression and Children’s Global Impression Scales

The Clinical Global Impressions Scale (CGI) is a clinician-rated mental health assessment tool used to establish the severity of illness at point of assessment (CGIS) and global improvement or change following care, treatment or intervention (CGIC). The CGIS is rated on a 7-point scale, with the severity of illness scale rated from 1 (normal) through to 7 (most severely ill). CGIC scores range from 1 (very much improved) through to 7 (very much worse).

The Children’s Global Assessment Scale (CGAS) is used in our child and adolescent services, providing  a global measure of level of functioning in children and adolescents. The CGAS is scored by the Multidisciplinary Team (MDT) on a scale of 1 to 100, which reflects the individual’s overall functioning level.
