BPRS - Brief Psychiatric Rating Scale 18-item
The Brief Psychiatric Rating Scale is an 18-item, provider-administered measure designed to assess positive, negative, and affective symptoms of individuals who have psychotic disorders.
The highest applicable rating is always assigned, even if the patient meets criteria for lower points as well. The rater must use a holistic perspective in deciding which anchoring point best characterizes the patient's functioning and rate accordingly, whether or not all elements of the description are observed.
