Subclaims¶

q3 i? Trait self-control and conscientiousness share 34% of variance, and conscientiousness showed slightly stronger associations with mGPA than trait self-control in the final model. → Schmidt FTC 2020

Evidence¶

Schmidt FTC 2020¶

Schmidt FTC, Lindner C, Etzel JM and Retelsdorf J (2020) Self-Control Outdoes Fluid Reasoning in Explaining Vocational and Academic Performance—But Does It? Front. Psychol. 11:757. https://doi.org/10.3389/fpsyg.2020.00757

q3 · i? · associational · r3

Correlational and regression results for N = 3,146 trainees; Table 1 prints a TSC–conscientiousness correlation of 0.58 ("shared variance 34%"), and the discussion notes conscientiousness "showed overall slightly stronger associations with mGPA".

"The relationship between trait self-control and conscientiousness was substantial (shared variance 34%)."
