The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor judgement, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score is the sum of all 30 PANSS items and ranges from 30 to 210, with 30 indicating absence of symptoms of schizophrenia and 210 indicating extreme ratings of all 30 symptoms. Negative change from baseline scores indicate improvements in symptoms.
Estimates (least square means and standard errors), 2-sided confidence intervals, and -1-sided P values are based on a repeated-measures linear regression model of the change from baseline score, with fixed effects for visit as a categorical variable, baseline score, treatment and treatment by visit interaction, assuming an unstructured covariance matrix.
