The PANSS is based on findings that schizophrenia comprises at least two distinct syndromes. The positive syndrome consists of productive symptoms, while the negative syndrome consists of deficit features. This distinction is useful when developing treatment plans because you can 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 you to determine which type of symptoms are being affected.

You have the option of using the standard Dimensional scoring, which is more focused on schizophrenia, or the new Pentagonal method of scoring, which is applicable to a wider range of populations (e.g., depression). The Pentagonal method uses 25 PANSS items organized into five scales: Negative, Positive, Dysphoric Mood, Activation, and Autistic Preoccupation.

Structured Clinical Interview for PANSS (SCI–PANSS) To optimize the instrument’s objectivity, the SCI–PANSS was developed to secure reliable information. The SCI–PANSS interview can be used to gather information objectively prior to completing the PANSS assessment.

Informant Questionnaire (IQ–PANSS)
The IQ–PANSS evaluates phenomenological presentation. Through item definitions, statements, and questions, the questionnaire ensures that all information related to behavioural presence, frequency, and responsiveness is obtained during interviews with family members, healthcare providers, or other informants.
