Studies suggest that gratitude contributes to the development of prosocial behaviors and strengthens interpersonal relationships. Research has suggested that grateful people are happier, more energetic, and have a higher hope of having positive experiences. There are currently several instruments available to measure gratitude, with the Gratitude Questionnaire-6 (GQ-6) being the most widely used. The GQ-6 is a self-report questionnaire with the objective of evaluating the willingness to experience gratitude, which is available in several languages and has been validated in different countries around the world. Its original six-item unifactorial structure has been replicated in several countries; however, a five-item unifactorial solution was more appropriate in some studies in the adult population. Despite the above, the factorial structure of the GQ-6 has not been explored in the Mexican population, so the objective of this study was to evaluate the psychometric properties of the GQ-6 in a Mexican sample. It was an instrumental study through non-probability sampling. The sample consisted of men and women aged 18 to 67 years. Participants were 566 adults of the general population (64.6% women and 35.5% men) from different states of Mexico. The GQ-6 was administered together with the Positive Affect and Negative Affect Scale (PANAS) and the Life Orientation Test (LOT-R). For the performance of EFA, the sample was divided in half randomly (N = 280). The analysis indicated a unifactorial structure with six indicators which explained 48.58% of the variance, which was maintained according to the sex of the participants (46.47% women and 46.66% men). Using the other half of the participants (N = 286), the CFA and the multigroup analysis were performed in relation to sex. The GQ-6 showed good fit and adequate internal consistency (α = .79) for both women (α = .77) and men (α = .76). Data on the convergent and divergent validity of GQ-6 showed a positive association with LOT-R (rs = .456, p < .001), Positive Affect (rs = .253, p < .001), and Negative Affect (rs = - .186, p < .001). Therefore, it can be concluded that GQ-6 is an instrument with good psychometric properties to evaluate the willingness to experience gratitude in the Mexican population.
