“…In line with previous investigations ( Gallant, Barry, & Good, in press ), the primary sport listed for current participation in university athletics was used as a means of classifying athletic status, such that 26 individuals self-identified as non-athletes (63%), 7 as low-risk athletes (17%), and 8 as high-risk athletes (20%). Of the 15 self-reported athletes, 10 (67%) currently participated in a recreational sports league and 5 (33%) participated in a competitive sports league.…”

IntroductionThis study investigated concussion as a potential risk factor for increased alcohol consumption in university athletes.MethodsUsing a cross-sectional design, 41 university students (37% with a history of concussion) completed self-report measures, while electrodermal activation (EDA) was recorded for each participant to capture baseline physiological arousal.ResultsAs expected, concussion status significantly predicted alcohol consumption over and above athletic status, b = 0.34, p = 0.034, 95% CI [0.195, 4.832], such that those with a prior concussion history engaged in greater alcohol consumption. Importantly, concussion status also significantly predicted baseline physiological arousal, b = −0.39, p = 0.014, 95% CI [−0.979, −0.120], such that those with a history of concussion exhibited lower EDA.ConclusionsElevated alcohol consumption among athletes is a pronounced associate of concussion in sports and may be a behavioral reflection of disruption to the orbitofrontal cortex – an area implicated in inhibition.

“…To capture possible differences in premorbid personality, participants were categorized into one of three categories (high‐risk, low‐risk, or nonathlete) based on the primary sport listed for current participation in university athletics (recreational or competitive). Specifically, in accordance with previous investigations (Gallant, Barry, & Good, 2018), high‐risk sports (e.g., Noble & Hesdorffer, 2013) were defined as those that pose a greater risk of sustaining an injury due to the inherent nature of the sport. High‐risk sports included ice hockey, rugby, soccer, wrestling, lacrosse, gymnastics, powerlifting, martial arts/karate, and cheerleading, while low‐risk sports included basketball, volleyball, rowing/kayaking, swimming, track and field, baseball, curling, ultimate frisbee, fencing, and flag football.…”

“…Based on the criteria outlined in Gallant et al. (2018), 18 participants self‐identified as nonathletes, 24 as low‐risk athletes, and 24 as high‐risk athletes. Twenty‐seven participants (41% of sample) reported a history of concussion—the majority of which were athletes (see Table 1)—and the average time since injury was 2.75 years ( M months = 32.96).…”

IntroductionResearch has indicated that athletes who engage in high‐risk athletic activities, such as football and hockey, have riskier personalities than their low‐risk and nonathlete counterparts (Ahmadi et al., 2011, Procedia Soc Behav Sci, 30 and 247–251; Zuckerman, 1983, Biological bases of sensation seeking, impulsivity, and anxiety, Lawrence Erlbaum Assoc Inc.). For instance, increased sensation‐seeking and aggression are common in high‐risk athletes, rendering these individuals more likely to sustain a subsequent injury, such as concussion. Elevated levels of certain personality traits, including impulsivity and aggression, have also been observed after concussion (Goswami et al., 2016, Brain Struct Funct, 221 and 1911–1925). The purpose of this study therefore was to determine whether aggressive behavior in university athletes may be accounted for, in part, by a history of concussion, rather than exclusively athletic status.MethodsUsing a quasi‐experimental design, 66 university students (n = 18 nonathletes, n = 24 low‐risk athletes, n = 24 high‐risk athletes) with (n = 27) and without a history of concussion (n = 39) completed the Buss & Perry Aggression Questionnaire (BPAQ; Buss & Perry, 1992, J Pers Soc Psychol, 63 and 452) and provided electrodermal activation (EDA) as an index of physiological arousal.ResultsIt was found that decreased physiological arousal among students with a history of concussion was associated with greater endorsement of physical aggression. Moreover, athletic status did not account for this pattern of aggression, as athletes and nonathletes did not differ in terms of self‐reported aggressive tendencies.ConclusionsPhysiological compromise after concussive injury may act as an independent mechanism of aggressive behavior in athletes beyond factors, such as athletic status.
