WHAT THE TEST MEASURES

About This Assessment

Scale for the Assessment of Prodromal Symptoms, SOPS Test

Scale of Prodromal Symptoms (SOPS) Test - Symptoms and Signs

psychopathology schizophrenia

This measure is used to structure the assessment of early, subthreshold psychotic-like experiences and related clinical features. The Scale of Prodromal Symptoms (SOPS) provides a standardized way to rate symptom presence and severity in individuals for whom an attenuated psychosis-risk presentation is being considered.

It consists of 19 items and typically takes about 4 minutes to administer. Items are commonly organized across positive, negative, disorganization, and general symptom domains, supporting symptom monitoring over time and informing clinical formulation. Developed by Scott W. Woods and Thomas H. McGlashan, the Scale of Prodromal Symptoms (SOPS) is intended for use by trained clinicians and should be interpreted in the context of clinical interview findings and other relevant information.
