Personality Predictors of Sports-Related Concussion Incidence: Analysis of Data from a Large, Heterogeneous Undergraduate Sample

Am J Phys Med Rehabil. 2021 Sep 28. doi: 10.1097/PHM.0000000000001901. Online ahead of print.


OBJECTIVE: Studies investigating the associations between personality and sports-related concussion (SRC) are limited. The current study aims to address this gap by examining if specific personality dimensions predicted self-reported SRC outcomes.

DESIGN: This study included 1141 undergraduate students (Mage = 19.47, SD = 2.14, female = 64.5%) who completed a battery of online personality measures and self-reported SRC items. The self-reported SRC outcomes included a single diagnosed SRC incident (i.e. “diagnosed SRC incidence”) and incidents of multiple diagnosed SRCs (i.e. “multiple diagnosed SRC incidents”). Analyses included splitting data randomly into training and validation datasets. Multivariate logistic regression models were then fit to each dataset to determine predictors of SRC.

RESULTS: In both training and validation datasets, extraversion and experience seeking were found to be positively and most strongly associated with both SRC outcomes, while motor inhibition was found to be negatively associated with both outcomes. Additional personality dimensions showed differential relations with each SRC outcome.

CONCLUSION: The current study highlights the importance of considering personality dimensions in the context of self-reported SRC outcomes, as there are differential relations between personality dimensions and these outcomes. Thus, prevention efforts for SRC may benefit from evaluating additional athlete factors, like personality traits.
