What is PANSS schizophrenia?
The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia. It was published in 1987 by Stanley Kay, Lewis Opler, and Abraham Fiszbein. It is widely used in the study of antipsychotic therapy.
Can the PANSS be used to diagnose schizophrenia?
The PANSS, SAPS, and SANS are well-established scales that have been used to objectively assess for schizophrenia symptoms. The fact that it is sensitive to change makes it a “gold standard” in treatment studies.
What do PANSS scores mean?
Measures. The PANSS yields a total average symptom score, based on 30 items rated from one to seven (range=30–210). Higher scores indicate more severe symptoms. 1. This study utilized PANSS results from baseline and 1, 3, and 6 month follow-up assessments.
When is PANSS used?
The PANSS (Kay et al., 1989) is a generic scale, which was designed to measure symptoms in schizophrenia and is commonly used in clinical trials of antipsychotic agents.

Can brain MRI detect schizophrenia?
INTERPRETATION. The research literature shows that schizophrenia has neuroanatomical correlates that can be seen at group level by studying MR images. Structural MRI cannot currently be used to identify schizophrenia at the level of the individual.
What is a clinically significant change in PANSS?
The minimum clinically important difference for PANSS scores using this scale equaled a 15.3-point (34.0%) change from baseline. A 1.96 SEM on the PANSS corresponded to a 16.5-point (36.2%) change from baseline.
How do you give a Panss scale?
CORE PRINCIPLES IN THE USE OF THE PANSS
- First principle—Read each item definition and all anchor points carefully and interpret each element as literally as possible.
- Second principle—Always give the highest rating that applies.
- Third principle—Always consider the reference period and time frame.
What does PANSS stand for in psychology?

Is PANSS a useful clinical screening tool for psychosis?
Despite complications with respect to length and ability to measure cognitive functioning, PANSS is considered a competent “stand-alone” clinical screening tool for psychosis due to its clinical predicting power and outcome. Newer studies communicate the following psychometric properties:
How reliable are schizophrenia scales?
Study of 101 schizophrenics found the four scales to be normally distributed and supported their reliability and stability. Positive and negative scores were inversely correlated once their common association with general psychopathology was extracted, suggesting that they represent mutually exclusive constructs.
What are the PANSS ratings based on?
Typically, the PANSS is rated based on a “past week” reference period (i.e. the ratings are based on the most severe phenomenon for a given item in the past week).
