Development and validation of a new scale to measure gratitude

A scale measuring the disposition of gratitude was designed and validated. The construct validity, convergent validity, internal convergent validity, discriminant validity, unidimensionality, internal consistency, construct reliability, and temporary stability of the scale were evaluated. The first study included 300 university students at different college programs; the second one included 118 undergraduate psychology students. The average age of the first group was Mean (Mage) = 20.29, Standard Deviation (SD) = 2.19, and 66.00% were women. The second group was Mage = 19.25 years old, SD = 1.54, and 65.30% were women. A good goodness of fit was obtained in both samples. The studies described here offer data about a new and brief scale to measure gratitude. This scale is recommended to be used by psychologists when they want to corroborate their clients are weak in gratitude or lacking on it, and/or to evaluate the effects of their interventions to enhance gratitude.
