The Validation of the Factor Structure of the Brief Psychiatric Rating Scale-Expanded Version (BPRS-E) with Geriatric and Nongeriatric Psychiatric Inpatients
The Brief Psychiatric Rating Scale-Expanded (BPRS-E) is a widely used outcome measure that assesses change in psychiatric symptoms. The focus of the present study was to clarify and determine the factor structure of the BPRS-E with geriatric and nongeriatric psychiatric inpatients. Two previous studies found different factor structures for the BPRS-E, raising questions regarding appropriate subscore interpretations. To carry out this exploratory study, factor analyses were conducted on the BPRS-E ratings of 564 adult patients (54 geriatric and 510 nongeriatric) at a state psychiatric hospital. Obtained results suggest that there is a stable factor structure within the BPRS-E that allows for the reliable and valid interpretation of subscores for geriatric and nongeriatric psychiatric inpatients by social work researchers and treatment providers.
