Is Grittiness Next to Happiness? Examining the Association of Triarchic Model of Grit Dimensions with Well-Being Outcomes

The present research explored the link of triarchic model of grit underpinned by three dimensions – perseverance of effort, consistency of interest, and adaptability to situations with well-being outcomes using a cross-cultural design among Filipino, Japanese, and Polish undergraduate students (Study 1), a cross-sectional design including Filipino employees (Study 2), and a longitudinal design involving Filipino high school students (Study 3). Study 1 demonstrated that perseverance was positively correlated with flourishing in Japanese undergraduate students. Adaptability was related to increased flourishing among Filipino, Japanese, and Polish students. Study 2 showed that both adaptability and perseverance positively predicted psychological flourishing in selected Filipino employees. Study 3 demonstrated that T1 perseverance and T1 adaptability positively predicted T2life satisfaction even after controlling for age, gender, previous GPA, and auto-regressor effects. However, all dimensions of grit did not predict T2flourishing. Implications of the results to advancing the extant grit theory are discussed.
