Background: The purpose of this study was to examine the interrelationships between personality, executive function (EF) and physical activity. Methods: Multivariable regression analyses examined the association between personality, executive function, and physical activity. Results: The personality trait agreeableness was positively associated with the percent of correct target detection for the Repeating Rule (β = 0.57; 95% CI: 0.09-1.04; P=0.01) and Stop Sign Rule (β = 0.57; 95% CI: 0.10-1.05; P=0.01) from an EF assessment. Mean reaction time for the Repeating Rule was inversely associated with moderate-to-vigorous physical activity (MVPA) (β = -1.90; 95% CI: -3.3, -0.4; P=0.01). Conclusion: The personality trait agreeableness was associated with greater EF, and greater EF, in turn, was associated with more MVPA.
