Primary use / Purpose:
Cronbach’s alpha estimates for the six-item totals have ranged from .76 to .84. Scores on the GQ-6 correlate substantially with other measures hypothesized to assess the extent to which people experience gratitude in daily life. McCullough, Emmons, & Tsang (2002) correlated the GQ-6 with a self-report measure that instructed participants to indicate how well each of three gratitude-related words (i.e., grateful, thankful, appreciative) described them. Scores on the two measures were correlated at r (N = 1182) = .65, p < .001. Using structural equation modeling to control measurement error, the correlation increased to r (N = 1182) = .75, p < .001. Scores on the GQ-6 also correlated with peers’ ratings of targets’ amounts of dispositional gratitude at r = .33, p< .01. Finally, people with high scores on the GQ-6 report feeling more “grateful,” “thankful,” and “appreciative” for benefits or gifts they have received than do people who score below the median on the GQ-6 (Gray, Emmons, & Morrison, 2002).
