The Posttraumatic Growth Inventory (PTGI) is a self-report instrument used to evaluate positive changes arising from coping with adversity. The current study aimed to investigate the factor structure of the Brazilian version of the instrument (PTGI-Br). A total of 321 subjects, who had experienced a variety of adverse events, participated in the study. Five different factor structure models of the PTGI-Br were tested through the confirmatory factor analysis method. The conventional five-factor model (relating to others, new possibilities, personal strength, appreciation of life and spiritual change) showed better fit indexes when compared to the other models. The factor structure of five first order factors organized around a global hi-order factor was also adequate. The result replicates the PTGI original structure. In addition, it allows the five dimensions of the PTGI-Br, as well as the global higher order dimension, to be used in statistical analysis.

Keywords : Posttraumatic Growth Inventory; validity evidence; confirmatory factor analysis; factor structure.
