Undergraduate freshmen’s self, parent, and peer ratings of Conscientiousness significantly predicted GPA at graduation; the other four five-factor personality domains did not correlate with undergraduate GPA

Prospective prediction of academic performance in college using self- and informant-rated personality traits. Morgan N. McCredie, John E.Kurtz. Journal of Research in Personality, Volume 85, April 2020, 103911. https://doi.org/10.1016/j.jrp.2019.103911

Highlights
•    Undergraduate freshmen’s self, parent, and peer ratings of Conscientiousness significantly predicted GPA at graduation.
•    Only peer ratings of Conscientiousness were significant when self, parent, and peer ratings were examined simultaneously.
•    The other four five-factor personality domains did not correlate with undergraduate GPA for any of the three raters.

Abstract: Five-factor personality ratings were provided by undergraduate freshmen, their parents, and their college peers as predictors of cumulative GPA upon graduation. Conscientiousness ratings were significant predictors of GPA by all three raters; peer ratings of Conscientiousness were the only significant predictor of GPA when self-, parent-, and peer-ratings of Conscientiousness were examined simultaneously. College major was a moderator of this relationship, with self- and parent-ratings of Conscientiousness correlating more strongly with GPA among Social Science majors and parent-ratings of Conscientiousness correlating less strongly with GPA among Science majors. These findings replicate existing research regarding the validity of informant ratings as predictors of behavioral outcomes such as academic performance, while emphasizing the importance of including multiple informants from various life contexts.
