Psychometric Properties of Positive and Negative Symptoms Scale (PANSS)

Psychometric Properties of Positive and Negative Symptoms Scale (PANSS)

The psychometric properties of the PANSS measure the severity of the positive symptoms, negative symptoms, and general psychopathology

symptoms once a patient has been diagnosed with schizophrenia and also in schizophrenia drug trials, a widely used measure of symptom severity, and

to track treatment response (Gopalakrishnan et al., 2020). The PANSS can be helpful in that it is used to identify the presence and severity of

psychopathology symptoms in schizophrenic patients. It has high internal reliability and validity in both positive and negative symptoms, and in short-

and long-term trials, an excellent sensitivity to change (Gopalakrishnan et al., 2020). According to Sadock et al. (2014), in assessing clinical outcomes in

treatment studies of schizophrenia and other psychotic disorders, the PANSS has become the standard tool and is easy to administer reliably and

sensitive to change with treatment.
