“Predicting Academic Success: General Intelligence, ‘Big Five’ Personality Traits, and Work Drive”, Susan D. Ridgell, John W. Lounsbury2004-12 (, )⁠:

General intelligence, Big 5 personality traits, and the construct Work Drive were studied in relation to two measures of collegiate academic performance: a single course grade received by undergraduate students in an introductory psychology course, and self-reported GPA.

General intelligence and Work Drive were found to be statistically-significantly positively related to both course grade and GPA, while one Big Five trait (Emotional Stability [Neuroticism]) was related to course grade only.

Hierarchical multiple regression analysis revealed the incremental validity of Work Drive beyond Emotional Stability and over and above general intelligence: Work Drive accounted for 7% and 14% of unique course grade and GPA variance, respectively, when Emotional Stability was entered last; and Work Drive accounted for 6% and 13% of unique course grade and GPA variance, respectively, when Work Drive was entered last. In both cases, Emotional Stability did not provide statistically-significant unique variance.

​Findings are presented and discussed in the context of examining how cognitive and noncognitive variables predict academic performance, and in terms of implications for using course grade versus GPA as a criterion for collegiate academic performance.
