BERNABE VALERO, Gloria; GARCIA-ALANDETE, Joaquín  and  GALLEGO-PEREZ, José Francisco. Comparative Analysis of two models of the Gratitude Questionnaire - Six Items Form. rev.latinoam.psicol. [online]. 2013, vol.45, n.2, pp.279-288. ISSN 0120-0534.

The aim of this study was to compare two models of the Gratitude Questionnaire - Form Six Items (GQ-6) by means of Confirmatory Factor Analysis: the 6 items originally proposed by its builders, and a 5-item validated by other authors. Both models showed fit indices, thereby suggesting adequacy thereof to the data; therefore the decision on choosing the best model was one of a theoretical nature. The 5-item approach was the most parsimonious, so it was chosen as the most appropriate approach as a valid and reliable scale was obtained with less reactives. We analyzed descriptive characteristics, internal consistency and convergent and discriminant validity of this model. The sample included 330 Spanish undergraduates (242 women, 88 men), aged 18-43, M_age = 23.33, SD = 4.87. Results showed an appropriate reliability, convergent validity, and discriminant validity of the 5 items scale.

Keywords : Gratitude; Factor Analysis; Test Reliability; Test Validity; Spanish Undergraduates.
