The PANSS is a clinician rated scale designed to measure severity of psychopathology in adult patients with schizophrenia, schizoaffective disorders and other psychotic disorders. It emphasizes positive and negative symptoms. The PANSS includes 3 sub-scales and 30 items: 7 items make up the positive scale (for example: delusions, conceptual disorganization and hallucinatory behaviour), 7 items make up the negative scale (for example: blunted affect, emotional withdrawal and poor rapport) and 16 items make up the general psychopathology scale (for example: somatic concern, anxiety and guilt feelings). Each item is rated from 1 (symptom not present) to 7 (symptom extremely severe). The PANSS total score is the sum of all items, and ranges from 30 to 210. Subscale scores are the sum of items within each subscale.

The CGI-SCH is a clinician-rated scale to assess global illness severity and degree of change in patients with schizophrenia. For both the global illness severity and degree of change, the CGI-SCH consists of four different groups of symptoms (positive, negative, cognitive, and depressive) and the overall severity of the disorder. The CGI-SCH-severity of illness symptoms and overall severity are rated on a 7-point scale ranging from 1 (normal - not ill) to 7 (Among the most severely ill). For the first four ratings (positive, negative, depressive, and cognitive symptoms), the assessment should focus on the severity of symptoms only. Additionally, for 'overall severity' rating, both severity of symptoms and interference with functioning should be considered.

The CGI-SCH is a clinician-rated scale to assess global illness severity and degree of change in patients with schizophrenia. For both the global illness severity and degree of change, the CGI-SCH consists of four different groups of symptoms (positive, negative, cognitive, and depressive) and the overall severity of the disorder. The CGI-SCH-degree of change symptoms and overall severity are rated on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Each single rating (conditions of severity and degree of change) and overall ratings of severity and improvement are scored independently and no total score is derived.
