Abstract

The Brief Bipolar Disorder Symptom Scale (BDSS) is a 10-item measure of symptom severity that was derived from the 24-item Brief Psychiatric Rating Scale (BPRS24). It was developed for clinical use in settings where systematic evaluation is desired within the constraints of a brief visit. The psychometric properties of the BDSS were evaluated in 409 adult outpatients recruited from 19 clinics within the public mental health system of Texas, as part of the Texas Medication Algorithm Project (TMAP). The selection process for individual items is discussed in detail, and was based on multiple analyses, including principal components analysis with varimax rotation. Selection of the final items considered the statistical strength and factor loading of items within each of those factors as well as the need for comprehensive coverage of critical symptoms of bipolar disorder. The BDSS demonstrated good psychometric properties in this preliminary investigation. It demonstrated a strong association with the BPRS24 and performed similarly to the BPRS 24 in its relationship to other symptom measures. The BDSS demonstrated superior sensitivity to symptom change, and an excellent level of agreement for classification of patients as either responders or non-responders with the BPRS24.
