PANSS
Pronunciation: panz
Also written as: PANSS — Positive and Negative Syndrome Scale
The Positive and Negative Syndrome Scale; a standardized 30-item rating instrument used to measure symptom severity in individuals with schizophrenia.
Full Definition
The PANSS was developed by Kay, Fiszbein, and Opler (1987) and remains the gold standard for quantifying psychotic symptom severity in clinical trials and treatment documentation. It rates 30 items across three subscales: positive symptoms, negative symptoms, and general psychopathology. In behavioral health editorial work, the PANSS appears in research summaries, medication review documents, utilization management letters, and grant applications. Editors should ensure the acronym is defined at first use and that subscale scores are reported consistently. Score interpretation conventions (e.g., 'mild,' 'moderate,' 'severe') should follow the scale's published anchor definitions.
Usage
Usage note: Always spell out in full at first use. Report subscale scores (positive, negative, general psychopathology) separately when included in clinical summaries.
