Positive and Negative Syndrome Scale (PANSS)

Positive and Negative Syndrome Scale (PANSS)

Quick Overview

PANSS is used to assess schizophrenia based on productive symptoms and deficit features of the two distinct syndromes of schizophrenia.

Product Description

The 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. This distinction is useful when developing treatment plans because it allows a focus on the type of symptoms the patient is experiencing. It is also useful when studying the effects of medication (e.g. in clinical drug trials) because it allows the determination of which type of symptoms are being affected.

Key Areas Measured
  • Positive Scale
  • Negative Scale
  • Composite Index
  • General Psychopathology Scale
  • Supplemental Aggression Risk Profile

In addition to standard Dimensional scoring, there is the option to use the new Pentagonal scoring method. The Pentagonal model is the result of recent research. It uses 25 PANSS items organised into five scales:

  • Negative
  • Positive
  • Dysphoric Mood
  • Activation
  • Autistic Preoccupation.
Structured Clinical Interview for PANSS (SCI–PANSS)

To optimise the instrument’s objectivity, the SCI–PANSS was developed to secure reliable information. It is a structured interview that can be used to gather information objectively prior to completing the PANSS.
Information Questionnaire (IQ–PANSS)
Through item definitions, statements, and questions, the IQ–PANSS ensures that all information related to behavioural presence, frequency, and responsiveness is obtained during interviews with family members, healthcare providers or other informants.

Glossary of terms Full specification

• Internal consistency (alphas) range from .72 to .81 for Positive, Negative and Global scales. For the sub-scales (which contain only three or four items) the internal consistencies still reach reasonable levels (.58 to .71).
• Re-test stability coefficients vary depending on chronicity and the time interval. In a sample of chronic schizophrenic patients they ranged from .60 to .80 over a 3-6 month interval; in a sample of sub-acute schizophrenic patients they ranged from .37 to .43 with an interval of 3-4 months; in a sample of acute schizophrenic patients they ranged from .18 to .24 over a 2 year period.
• Mean inter-rater correlations range from .83 to.87.

Research presented in the Manual supports the construct, discriminant, convergent and predictive validity of PANNS.
