Description

PSRS is a psychiatric assessment that has been modified from a longer form of the BPRS (Brief Psychiatric Rating Scale) to assess temporal paranoia or agitation. The PSRS consists of a 4-item Positive Symptom Rating Scale (1. Suspiciousness; 2. Unusual Thought Content; 3. Hallucinations; 4. Conceptual Disorganization). It is an interviewer-administered assessment. The responses for the Positive Symptom Rating Scale are rated on a 7-point scale (1. Not Present; through 7. Extremely Severe).
