FILGUEIRAS, Alberto et al. Development and psychometric properties of a novel depression measure. Temas psicol. [online]. 2014, vol.22, n.1, pp.249-269. ISSN 1413-389X.  https://doi.org/10.9788/TP2014.1-19.

The Filgueiras Depression Inventory is proposed as a new instrument, created specifically for the Brazilian culture, for screening of Major Depressive Episodes according to the categories of the DSM-V. Two studies were conducted for this purpose. Study's 1 sample consisted of 326 undergraduate psychology students. Single words or expressions were asked to represent overall depressive symptoms. The most cited formed the first version of the Filgueiras Depression Inventory. Study 2 reported the psychometric properties of this new scale. The sample consisted of 471 volunteers recruited on the Internet and 238 volunteers undergraduate students. Factor analyses, convergent and discriminant validity and other Classical Test Theory indices revealed results consistent to expectations in the present study. Andrich's Rating Scale Modeling was used as an Item Response Theory method of analysis. The overall psychometric properties of the Filgueiras Depression Inventory were shown to be good, and this study supports the effectiveness of this scale as a new instrument that measures depressive episodes in the Brazil.
