| Description | The Brief Psychiatric Rating Scale (BPRS; Overall & Gorham, 1962) is a 16-item tool designed for efficient evaluation of psychiatric symptoms and the efficacy of pharmacologic treatments. Derived from longer scales like the Lorr Multidimensional Scale for Rating Psychiatric Patients (MSRPP) and the Lorr Inpatient Multidimensional Psychiatric Scale (IMPS), the BPRS provides a concise yet comprehensive assessment of major psychiatric symptoms. It supports structured interviews, with recommended timing: 3 minutes for rapport, 10 minutes for non-directive interaction, and 5 minutes for direct questioning. Trained raters can complete evaluations in 2–3 minutes. Reliability was assessed through inter-rater correlations ranging from .56 (Tension) to .87. |
