Validity of the Brief Psychiatric Rating Scale Within a Forensic Inpatient Hospital

Abstract

Although the Brief Psychiatric Rating Scale(BPRS) has been utilized across several clinical settings, its potential utility within forensic psychiatric hospitals has not yet been investigated. Given the diversity of training and background among correctional mental health workers (i.e., psychiatrists, psychiatric nurses, occupational therapists, recreation therapists, psychologists, social workers,etc.) it is possible that the uniform use of the BPRS among the correctional staff would require extensive training and that substantial “refresher” training may be required to maintain the integrity of rater practices. The present study examined the ability of previously trained forensic mental health professionals to accurately assess psychopathology using the BPRS. Overall,experienced raters demonstrated relatively high concordance rates with “gold standard” ratings across three BPRS training videos (Case 1, Case2 and Case 3). No overall “rater drift” was apparent. However, raters were found to make significantly more errors when rating behavioral observation ratings than for ratings based on self-report patient statements. Findings suggest that ratings done by forensic mental health workers are relatively accurate when compared to “gold standard” ratings established for assessment of community and forensic psychiatric patients.
