Outcome Measures

Primary Outcomes (1)

  • Positive and Negative Symptom Scale

    The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia. To assess a patient using PANSS, an approximately 45-minute clinical interview is conducted. The patient is rated from 1 to 7 on 30 different symptoms based on the interview as well as reports of family members or primary care hospital workers. Subjects can not score lower than 30 or higher than 210. Higher score indicates higher amount of psychopathology
