CGI-S guidelines
| 1 = Normal—not at all ill, symptoms of disorder not present past seven days |
| 2 = Borderline mentally ill—subtle or suspected pathology |
| 3 = Mildly ill—clearly established symptoms with minimal, if any, distress or difficulty in social and occupational function |
| 4 = Moderately ill—overt symptoms causing noticeable, but modest, functional impairment or distress; symptom level may warrant medication |
| 5 = Markedly ill—intrusive symptoms that distinctly impair social/occupational function or cause intrusive levels of distress |
| 6 = Severely ill—disruptive pathology, behavior and function are frequently influenced by symptoms, may require assistance from others |
| 7 = Among the most extremely ill patients—pathology drastically interferes in many life functions; may be hospitalized |
