The purpose of this study was to examine whether higher-order gratitude consisting of multiple components (i.e., thanking others, thanking God, cherishing blessings, appreciating hardship, and cherishing the moment) explains variances in integrated mental well-being, including depression, self-esteem, and psychological well-being after controlling for gender, age, religion, the Big Five personality traits (i.e., openness, conscientiousness, extraversion, agreeableness, and neuroticism), and unifactorial gratitude (GQ). A total of 231 participants were recruited to complete questionnaires measuring the variables of interest. The results indicated that higher-order gratitude made a significant unique contribution to psychological well-being, self-esteem, and depression (3 % to 5 % of the variance, p < .05) above the effects of demographic variables, personality traits, and unifactorial gratitude. These findings suggested that higher-order gratitude is more than just personality traits or unifactorial gratitude, and it is important in its own right for integrated mental well-being.
