Abstract

The present study aimed to find  evidences of validity (based on the internal structure) for the Baptist Depression Scale Hospital-Ambulatory Version (EBADEP-HOSP-AMB), using exploratory factor analysis and Item Response Theory (IRT). Two hundred and ten patients with chronic renal disease (CRD) on hemodialysis, of both sexes, aged 18-82 years, participated in the study. Using exploratory factor analysis, the instrument was reduced from 43 to 20 items, in two factors initially named "Negative Aspects" (14 items) and "Positive Aspects" (6 items), which explain 56% of item variance. Reliability indexes for those factors were 0.95 and 0.89, respectively. Using IRT, the parameters of both items and persons were verified, and good adjustment indexes were obtained for the two factors of EBADEP-HOSP-AMB. We conclude that the instrument had good psychometric properties and could be a tool for screening depressive symptomatology in hospital / outpatient settings; other studies with more representative samples are necessary to carry out new analyzes.
