Positive and Negative Syndrome Scale (PANSS)
composes of 3 components: Positive (P), Negative
(N) and cognitive or General Psychopathology (G).
Positive syndrome is composed of symptoms such
as delusions, hallucinations and disorganized
thinking. Negative syndrome is characterized by
deficits in cognitive, affective, and social functions,
including blunting of affect and passive withdrawal.
General Psychopathology is composed of many
deficits in cognition such as disorientation, poor
attention, lack of insight and active social
avoidance.
Positive and Negative subscales each contain 7
items (P1 – P7, N1 – N7); General Psychopathology
subscale contains 16 items with the major emphasis
on cognition (G 1 - G16) (Table 1).
Each item is scored from 1-7 based on the
presence and severity of symptoms: (1 = absent, 2
= minimal, 3 = mild, 4 = moderate, 5 = moderate
severe, 6 = severe, 7 = extreme).
