A revised anchored version of the BPRS-C for childhood psychiatric disorders.

The Brief Psychiatric Rating Scale for Children (BPRS-C) is increasingly used as an outcome measure in research, managed care, and public sector child/adolescent clinical settings. The BPRS-C was developed to provide a descriptive profile of symptoms applicable to a broad range of child and adolescent psychiatric disorders. Its use frequently includes trained and untrained clinician raters with differing degrees of experience and training in child and adolescent disorders. Unfortunately, this latter approach leads to a large amount of variability in scores and consequently reduces its overall reliability. This study reports on a revised BPRS-C with the addition of clinical descriptive anchors designed to improve reliability and validity for both trained and untrained raters. A sample of 4,733 children and adolescents seen in 10 public sector facilities was administered the BPRS-C along with other standard clinical measures (Child Behavior Checklist and Global Assessment of Functioning). Additional reliability data were gathered in a University Medical Center child and adolescent research site with both trained and untrained raters. The data indicated improvement in overall reliability and validity scores, good internal consistency, and improved factor scores. The addition of an overall total severity score may prove to be a useful outcome measure for assessment of treatment response.
