Developed by M. Hamilton, this widely-used interview scale measures the severity of a patient's anxiety, based on 14 parameters, including anxious mood, tension, fears, insomnia, somatic complaints and behavior at the interview. Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where \<17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.

The Global Assessment Scale (GAF) is a hypothetical continuum of mental health illness that looks at psychological, social, and occupational functioning. It measures how much a person's symptoms affect their day-to-day life on a scale of 0 to 100. A score of 100-91 indicates no symptoms, 90-81 indicates absent minimal symptoms, 80-71 indicates symptoms that are transient and reactions expectable to psychosocial stressors, 70-61 indicates mild symptoms, 60-51 indicates moderate symptoms, 50-41 indicates serious symptoms, 40-31 indicates some impairment in reality testing or communication OR major impairment in several areas, 30-21 indicates delusions or hallucinations, 20-11 indicates danger of hurting self or others OR occasionally fails to maintain personal hygiene, 10-1 indicates persistent danger of severely hurting self or others OR persistent inability to maintain minimal personal hygiene OR serious suicidal act with clear expectation of death and 0 indicates inadequate data.

The Quick Inventory of Depressive Symptomatology Self Report (QIDS- SR) is a 16-question shortened self-test, derived from the 30-item Inventory of Depressive Symptomatology (IDS). Questions in the QIDS - SR-116 correlate with the nine Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) symptom criterion domains, Including: Sleep disturbance (initial, middle, and late insomnia or hypersomnia) (Q 1 - 4), Sad mood (Q 5), Decrease/increase in appetite/weight (Q 6 - 9), Concentration (Q 10), Self-criticism (Q 11), Suicidal ideation (Q 12), Interest (Q 13), Energy/fatigue (Q 14), Psychomotor agitation/retardation (Q 15 - 16). The severity of depression can be judged based on the total score. A score of 1-5 indicates No depression, 6-10 indicates Mild depression, 11-15 indicates Moderate depression, 16-20 indicates Severe depression and 21-27 indicates Very severe depression.

The CGI severity of illness scale is a simple validated, single-item, 7-point self-reported categorical scale ranging from 0-7 where 0 indicates not assessed; 1 indicates normal, not at all ill; 2 indicates borderline mentally ill; 3 indicates mildly ill; 4 indicates moderately ill; 5 indicates markedly ill; 6 indicates severely ill; and 7 indicates among the most severely ill patients.
