The PANSS assessment helps you evaluate schizophrenia.  It provides a broad-based, standardised evaluation of psychopathology dimensions that help to characterise a client's clinical profile and monitor treatment changes.

The PANSS assessment is based on findings that schizophrenia comprises at least two distinct syndromes:  the positive syndrome consists of productive symptoms such as hallucinations and delusions and usually responds well to neuroleptic treatment; the negative syndrome consists of deficit features such as blunted affect and passive social withdrawal, which indicates poor premorbid status, neuroleptic resistance and poor prognosis.

The PANSS assessment consists of a 30- to 40-minute formalised psychiatric interview in which 30 symptoms are rated on a 7-point scale.  The assessment yields separate scores along nine clinical dimensions including the positive and negative syndromes, depression, a Composite Index and general psychopathology.

The IQ-PANSS questionnaire evaluates phenomenological presentation in a reliable and valid manner.  Through item definitions, statements, and questions, the questionnaire ensures that all information related to behavioural presence, frequency and the client's responsiveness is obtained during interviews with family members, healthcare providers or other informants.

With the PANSS hand score Form, your responses transfer through to a hidden scoring page where you are guided through simple calculations to obtain scores.  Raw scores are plotted on a Profile Sheet for quick conversion to T-scores.
