LIMA-CASTRO, Sandra et al. Adaptation and Validation of the Gratitude Questionnaire GQ-6 for the Ecuadorian Context. Aval. psicol. [online]. 2019, vol.18, n.2, pp. 129-137. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2019.1802.15689.03.

This paper evaluates the factor structure, reliability and validity of the gratitude scale (GQ-6) of McCullough, Emmons and Tsang (2002) and the five-item version proposed by Chen et al. (2009). Results of a sample of 1112 adults show that the five-item version has excellent internal consistency (α = .926; ω = .891; GLB = .913); high and significant factor loadings (greater than .8; p <.01), and excellent goodness of fit indexes (χ² (5) = 23.837, p <.001; CFI = .997; TLI = .995; RMSEA =. 082, p = .045; SRMSR = .035; WRMSR = .837). The criterion validity was evaluated applying subscales of the PERMA-Profiler: positive emotions (ρ = .5702, p = .021) and negative emotions (ρ = -.1786, p = .0316). Finally, we find psychometric equivalence between the sex of the participants. In conclusion, the five-item questionnaire is valid and reliable in the Ecuadorian context.
