Scale for the Assessment of Positive Symptoms (SAPS) Test

psychopathologyschizophrenia

This clinician-rated instrument is used to quantify the severity of positive psychotic symptoms through interview and behavioral observation. The Scale for the Assessment of Positive Symptoms (SAPS) provides a structured approach to documenting symptom presence and intensity in domains commonly associated with psychosis.

The measure includes 34 items and typically requires about 7 minutes to administer and score, depending on clinical complexity and the amount of collateral information available. It is commonly used in clinical and research settings to support baseline characterization and longitudinal monitoring of symptom change; the original measure was developed by Nancy C. Andreasen.

The Scale for the Assessment of Positive Symptoms (SAPS) is intended to complement broader diagnostic and clinical evaluation rather than function as a stand-alone diagnostic tool, and interpretation should be integrated with the full clinical picture, including mental status findings and relevant history.
