Results: The mTBI group showed a trend-level negatively correlation with dominance (r_mTBI= -0.141, p=0.092), while the healthy control group was weakly positively correlated (r_HC= 0.229, p=0.166), but directionality was different between the groups (Fisher’s r-to-z comparison, z=-2.02, p=.04). Conclusions: In the mTBI group, dominance, a trait described as a confident and assertive personality, had a trend level inverse association with attention performance. However, this was not observed in the HC group (although the healthy control group was much smaller and weakly powered). This analysis suggests that mTBI patients may be more vulnerable to these cognitive biases, or more likely to have poor judgement and awareness of their own abilities. The relationship between dominance and scores on attention indexes should be explored with larger sample sizes from mTBI populations. Future research should include a larger control group and look at other cognitive domains frequently impacted by mTBI to determine if this pattern persists in domains outside of attention only.

Objective:

Mild traumatic brain injury (mTBI) contributes to cognitive deficits post-injury. It is well established that domains such as memory, attention, and decision-making can be impacted severely. Here, we investigate attention abilities in those with mTBI, and how personality may play a role. The Dunning-Kruger effect describes a cognitive bias in which those who have little experience in a task tend to be overconfident and overestimate their performance. We hypothesized that the trait of dominance would be more greatly associated with performance on attention tasks in the healthy control (HC) group compared to those diagnosed with mTBI.

Participants and Methods:

There were 151 adults with mTBI between the ages of 18 and 45 that completed this study (M_age= 24.5 years, SD=7.7), including 56 males and 95 females (62.9% female). There were also 39 healthy adults that completed this study, made up of 15 males and 24 females (61.5% female) between the ages of 19 and 45 (M_age=24.3 years, SD=5.7). All participants completed several questionnaires, neurocognitive assessments, and neuroimaging sessions. In this analysis, we examined at the dominance subscale in the Personality Assessment Inventory (PAI) and the attention index of the Repeated Battery for Assessment of Neuropsychological Status (RBANS). Initially, a Pearson correlation was conducted to determine if there was a difference in the strength of association between PAI dominance scores and RBANS attention index scores for the mTBI and healthy control (HC) groups and compared the strength and directionality between the two groups using a Fisher’s r-to-z transform and z-test.

Results:

The mTBI group showed a trend-level negatively correlation with dominance (r_mTBI= -0.141, p=0.092), while the healthy control group was weakly positively correlated (r_HC= 0.229, p=0.166), but directionality was different between the groups (Fisher’s r-to-z comparison, z=-2.02, p=.04).

Conclusions:

In the mTBI group, dominance, a trait described as a confident and assertive personality, had a trend level inverse association with attention performance. However, this was not observed in the HC group (although the healthy control group was much smaller and weakly powered). This analysis suggests that mTBI patients may be more vulnerable to these cognitive biases, or more likely to have poor judgement and awareness of their own abilities. The relationship between dominance and scores on attention indexes should be explored with larger sample sizes from mTBI populations. Future research should include a larger control group and look at other cognitive domains frequently impacted by mTBI to determine if this pattern persists in domains outside of attention only.
