Normalization procedure for the Baptista Depression Scale - Adult Version (EBADEP-A): Transferring of norms

Abstract

Regarding the standardization of psychological instruments, that is, the construction of referential interpretations of a test, we can find different procedures performed both by Classical Test Theory and the Theory of Item Response. Especially in this case (IRT), we can admit one test as a default, so to use its standardization and transfer the cut-off point to another instrument. Based on this information, the present study aimed to provide a cutoff score for the Baptista Depression Scale-Adult Version (EBADEP-A) through procedures of norms-transfer based on the Center for Epidemiologic Studies – Depression Scale (CES-D). The EBADEP-A presented good distribution and ability to discriminate depressive symptoms, and the sample, consisting of Brazilian College students, received a cutoff score of 32 points. It is emphasized that this is an exploratory and preliminary study, and it is suggested further analyzes to be performed with clinical samples for which results can be corroborated or confronted.
