The PANSS evaluates the severity of various symptoms of schizophrenia, and is commonly used to measure symptom reduction in patients taking antipsychotics. Each item is scored on a 7-point severity scale (1=absent; 2=minimal; 3=mild; 4=moderate; 5=moderate severe; 6=severe; 7=extreme). The PANSS total score is derived from the summation of each item. A higher score indicates greater severity.
