Abstract
Background. Studies have shown that individuals suffering from Mild Traumatic Brain Injury (MTBI) may display pre-MTBI personality traits- one of the pre-injury factors that are associated with post-concussion symptoms (PCS) and their persistence (Persistent PCS).Aims. Few studies have explored this relationship, especially the employment of the Five-Factor Model (FFM) trait dimensions and exploration of their relations with specific clusters of PCS (somatic-emotional and cognitive). Hence, this essay aims to evaluate the relationships and assess if pre-MTBI personality traits conceptualised under the FFM are predictive of Somatic-Emotional and Cognitive PCS. Demographic factors within three months (Time-1), after three months post-MTBI (Time-2) and severity scores differences between the two time-points (Changed T1-T2) will be controlled for.Methods. Three linear regression and 4 hierarchical multiple regressions analyses were run to assess whether the retrospectively rated pre-injury personality subscales predict PCS Somatic-Emotional and Cognitive at Time-1, Time-2 and Change their change in severity between Time-1 and Time-2 (Change T1-T2) while controlling for demographic factors that had significant correlation or effect size approaching .3 or above (r? .3).Results. In combination, personality traits (Self-Reproach, Negative Affect, Intellectual Interest and Non-antagonistic Orientation) and specific demographic factors were predictive of PCS Cognitive at Time-1 and Time-2, plus PCS Somatic-Emotional at Time-2. However, only trait Intellectual Interest uniquely contributed 10% of PCS Cognitive at Time-2 variance. No other unique individual factors were found.Discussions & Conclusion. Further studies may look into considering demographics
, pre-MTBI, peri-MTBI and post-MTBI factors in a larger sample with a shorter time gap between the individual’s MTBI occurrence and baseline assessment. Additionally,evaluating the cognitive mechanisms where personality traits may influence the PCS experience is also recommended.
