Abstract
Rationale The expanded version of the Brief Psychiatric Rating Scale (BPRS-E) has improved the instrument's coverage and interrater reliability, but there is little knowledge on its subsyndromes. Objectives To assess: (1) whether there are common underlying BPRS-E subscales in patients living in different countries and (2) if this is the case, whether these subscales behave the same in all populations and, if not, what are the differences over these populations.
