Positive and Negative Syndrome ScalePANSS
- The Positive and Negative Syndrome Scale (PANSS™) helps measure the positive and negative syndromes of schizophrenia and other psychoses to develop treatment plans. The PANSS is also helpful when studying the effects of medication (e.g., in clinical drug trials) because it allows you to determine which type of symptoms are being affected.

The Positive and Negative Syndrome Scale (PANSS™) is based on findings that schizophrenia comprises at least two distinct syndromes: the positive syndrome, consisting of productive symptoms; and the negative syndrome, consisting of deficit features. It is useful when developing treatment plans because you can focus on the type of symptoms the patient is experiencing. The PANSS is also helpful when studying the effects of medication (e.g., in clinical drug trials) because it allows you to determine which type of symptoms are being affected.
Key Areas Measured
Structured Clinical Interview for PANSS (SCI-PANSS)
Informant Questionnaire (IQ-PANSS)
How to Use
The PANSS is a hand scored instrument. It can be scored using the standard Dimensional scoring or the Pentagonal scoring method. The Pentagonal method uses 25 PANSS items organized into five scales: Negative, Positive, Dysphoric Mood, Activation, and Autistic Preoccupation.
Reliability and Validity
Thirty years of research support the use of the PANSS as a psychometrically sound measure of the presence and severity of symptoms of schizophrenia. The scales have demonstrated excellent internal consistency (coefficient alpha and split-half reliability) and consistency over time (test-retest reliability) while still being sensitive to change. The PANSS Positive and Negative symptom ratings are highly correlated with the Anderson method for evaluation, and the General Psychopathology scale has demonstrated significant associations with the NIMH Clinical Global Impression Scale.
