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 and reported their motivation for an academic goal. 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 for research on self-regulatory traits are discussed.
