SIGMA-VB: Validity and reliability of the Brazilian Portuguese version of the Montgomery-Asberg Depression Rating Scale using the Structured Interview Guide for the MADRS.

ABSTRACT:

Objective

The Montgomery-Åsberg Depression Rating Scale (MADRS) is widely used to assess depression severity. The Structured Interview Guide for the MADRS (SIGMA) was created to standardize MADRS assessment. The objective of this study was to translate and validate the original SIGMA into a Brazilian Portuguese version (SIGMA-VB).

Methods

We translated and cross-culturally validated the original SIGMA into the SIGMA-VB, and assessed its psychometric properties using data from 93 adult outpatients enrolled in the Integral Assessment in Unipolar Depression (AIUNI) trial. Participants were assessed by two raters on five visits over 8 weeks. We calculated multiple interrater reliability indexes for the SIGMA-VB and used the Hamilton Depression Hating Scale (HAM-D) for validation
