Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 24
Časové okno: Baseline, Week 24
|
The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme).
The total score ranges from 30 to 210 and higher score indicates greater severity.
