Abstract
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.
