This study evaluated the factorial validity and internal consistence of the Brazilian version of the 28-item Goldberg General Health Questionnaire (QSG-28), comparing the four, three and five factor adjustments of its factorial structure. A reverse translation procedure (English-Portuguese-English) of the instrument was carried out. We applied the QSG-28 with 878 students from two colleges in Belo Horizonte/MG. Exploratory factorial analysis, Smallest Space Analysis and confirmatory factorial analysis (CFA) were performed. In the CFA, none of the models presented a good fit. The three-factor model of the QSG-28 was more appropriate than the four- and five-factor models for the evaluation of college students, although the four-factor model could be adopted. It was concluded that the instrument is an alternative for screening for changes in mental health in non-clinical individuals and can be used in occupational studies.

Keywords : GHQ-28; confirmatory factor analysis; college students.
