Abstract from the research paper: 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.




For simplicity, only the mother's and father's ratings for the student are given. The variable name indicates whose rating and on what scale, e.g. m_extra is the mothers rating on the extraversion scale. Other variables are:

  • subjid: Unique ID for the student

  • age: The student's age when the ratings were collected

  • GPA: The student's eventual 4-year grade-point average

  • sex: The student's sex

  • field: What field the student ended up studying
