Scoring & interpretation
The SOPS comprises 19 items divided into four domains: positive, negative, disorganization and general symptoms. Each item is rated from 0 (absent) to 6 (severe and psychotic). The total score and the subscale scores make it possible to describe the patient's symptom profile and to detect a possible risk of transition to psychosis.
