Personality traits and general intelligence as predictors of academic performance: A structural equation modelling approach

Abstract

The aim of the present study was to investigate the extent to which personality traits, after controlling for general intelligence, predict academic performance in different school subjects. Upper secondary school students in Sweden (N=315) completed the Wonderlic IQ test (Wonderlic, 1992) and the IPIP-NEO-PI test (Goldberg, 1999). A series of hierarchical structural equation models showed that general intelligence, Conscientiousness, Extraversion and Neuroticism were significantly linked to overall academic performance. There were also different findings for a lower level of personality traits, e.g. different personality traits were associated with different subjects. The findings are discussed with regard to previous results on personality traits as determinants of academic performance in different school subjects and the fact that lower level traits may facilitate achievement in particular subjects.
