Primary use / Purpose:
The GRAT was designed to measure an individual’s dispositional gratitude.
The authors proposed several traits that that a grateful person would exhibit. A grateful person would not feel deprived in life, they would have a sense of abundance. They would acknowledge the contribution of others to their success and well-being, would appreciate life’s simple pleasures, and would acknowledge the importance of experiencing and expressing gratitude. Their conceptualisation of gratitude was shown to correlate with measures of subjective well-being and positive affect.
The revised Gratitude Resentment and Appreciation Test (GRAT) consists of 44 items measuring these characteristics. The short-form GRAT consists of 16 items. Both scales are rated on a nine point scale from I strongly disagree to I strongly agree with the statement.
The revised GRAT has been shown to have good internal consistency, factorial validity, construct validity, and temporal stability (Watkins et al., 2003)
