In four studies, the authors examined the correlates of the disposition toward gratitude. Study 1 revealed
that self-ratings and observer ratings of the grateful disposition are associated with positive affect and
well-being, prosocial behaviors and traits, and religiousness/spirituality. Study 2 replicated these findings
in a large nonstudent sample. Study 3 yielded similar results to Studies 1 and 2 and provided evidence
that gratitude is negatively associated with envy and materialistic attitudes. Study 4 yielded evidence that
these associations persist after controlling for Extraversion/positive affectivity, Neuroticism/negative
affectivity, and Agreeableness. The development of the Gratitude Questionnaire, a unidimensional
measure with good psychometric properties, is also described.
