University Student Depression Inventory, Brazilian Version, Construct Assessment

Abstract

Objectives: to assess the University Student Depression Inventory, Brazilian version (USDI-BR), construct. Methods: a methodological study carried out with a snowball probabilistic sample, consisting of 334 undergraduate and graduate students. Confirmatory factor analysis, reliability using McDonald’s omega coefficient and Cronbach’s alpha were performed. Principal component analysis was performed using the varimax rotation and oblimin rotation, using the Kaiser-Meyer-Olkin criteria, Bartlett’s test of sphericity and scree plot. Results: the USDI-BR presented an internal consistency of items of ω = 0.95 and remained with 30 items, with the addition of 1 factor (Death wish and social withdrawal), totaling 4 factors. Conclusions: the USDI-BR has evidence that points to its validity and also its internal consistency, deserving that new studies be carried out to expand the evidence of its psychometric properties.
