Examining the unique and combined effects of grit, trait self-control, and conscientiousness in predicting motivation for academic goals: A commonality analysis

The purpose of the present research was to examine the predicative ability of both the unique and combined components of grit, trait self-control, and conscientiousness in the context of academic goal pursuit. Participants (n1=163, n2=551) were asked to complete assessments of each self-regulatory trait. They also identified three goals that they planned to pursue over the next year and rated their motivation for pursuing them, of which we retained only academic goals. Together, grit, trait self-control, and conscientiousness explained 9.9% of the variance in academic goal motivation across both samples. Using commonality analysis, we found that the overlapping components of grit, trait self-control, and conscientiousness accounted for 49.6% of the explained variance (4.9% of the total variance), with the individual components each accounting for less than 20% (2% of the total variance). Implications and suggestions for subsequent research on self-regulatory traits are discussed.
