This study aimed to evaluate the psychometric properties of the Gratitude Questionnaire (GQ-6) to the Brazilian population. The sample consisted of 1 850 participants with a mean age of 25.13 years (SD = 5.36), 50 % female and 50 % male and the sample represents all Brazilian states. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were run, along with correlations between gratitude (GQ-6) and life satisfaction (SWLS), optimism (LQT-R), hope (AHS), happiness (SHS), positive and negative affects (PANAS), and personality (BFI). The EFA and CFA results indicated a one-dimensional solution with the items loading satisfactorily (λ > 0.39) in the factor and acceptable fit for the one-factor solution (X 2 (9) = 59, p < 0.001; CFI = 0.956, RMSEA = 0.078). Correlations indicate relevant relationships with external variables. In conclusion, the questionnaire shows evidence of validity and reliability for research use in the Brazilian context.
