The COVID-19 pandemic caused significant disruption during the spring of 2020. Many college students were told to leave campus at spring break and to complete the semester remotely. This study evaluates effects of this disruption on student well-being. Measures of psychological symptoms, perceived stress, and alcohol use during the pandemic were completed by 148 students in spring 2020 and 352 students in fall 2020 at a university in the southeastern U.S. Results from both cohorts were compared to 240 students who completed the same measures in the fall 2019 semester. Participants in spring 2020 reported more mood disorder symptoms, perceived …

Although the notion that alcohol promotes violence is widespread, not all individuals are aggressive while intoxicated. Genetic variation could be a contributing factor to individual differences in alcohol-heightened aggression. The present study examines the effects of OPRM1C77G genotype on responses to threat in rhesus macaques under normal conditions and following alcohol administration. Prior studies have shown that a low CSF level of 5-HIAA is a trait marker for individuals prone to escalated aggression. We wanted to examine whether the predictive value for this marker on aggression was moderated by OPRM1 genotype. Animals were administered alcohol (BAC 100-200 mg%), were provoked …

The intracellular parasite Toxoplasma gondii (Nicolle et Manceaux, 1908) infects humans resulting in acute toxoplasmosis, an infection that in immunocompetent people is typically mild but results in persistent latent toxoplasmosis. In that T. gondii appears to affect dopamine synthesis and because addicting drugs affect midbrain dopamine transmission, latent toxoplasmosis could influence substance use. Using both the third and continuous National Health and Nutrition Examination Surveys from the US Centers for Disease Control and Prevention, we used logistic regression to test for associations between T. gondii seropositivity and subject self-report of having ever used tobacco, alcohol, marijuana, cocaine, heroin, or methamphetamine. …
Effects Of Exposure To Alcohol-Related Cues On Racial Discrimination, Elena V. Stepanova, Bruce D. Bartholow, J. Scott Saults, Ronald S. Friedman
Effects Of Exposure To Alcohol-Related Cues On Racial Discrimination, Elena V. Stepanova, Bruce D. Bartholow, J. Scott Saults, Ronald S. Friedman

Prior research has shown that exposure to alcohol‐related images exacerbates expression of implicit racial biases, and that brief exposure to alcohol‐related words increases aggressive responses. However, the potential for alcohol cue exposure to elicit differential aggression against a Black (outgroup) relative to a White (ingroup) target—that is, racial discrimination—has never been investigated. Here, we found that White participants (N = 92) exposed to alcohol‐related words made harsher judgments of a Black experimenter who had frustrated them than participants who were exposed to nonalcohol words. These findings suggest that exposure to alcohol cues increases discriminatory behaviors toward Blacks.

Prior research (Stepanova, Bartholow, Saults, & Friedman, 2012) indicates that exposure to alcohol-related cues increases expressions of racial biases. This study investigated whether such effects can be replicated with other tasks assessing racial bias and whether they stem from stereotyping or prejudice. In two experiments participants (N1 = 118; N2 = 152) were exposed to either alcohol-related or neutral advertisements, and then completed a race-priming lexical decision task (LDT, Wittenbrink, Judd, and Park, 1997). Experiment 1 provided weak evidence that exposure to alcohol cues decreases positive attitudes toward Blacks, which was not confirmed in a high-powered replication …

Objective: To explore gender differences regarding weight management behaviors of college drinkers. Participants: Nationally representative sample of college students from the fall 2008 American College Health Association’s National College Health Assessment II (N = 26,062 students). Methods: Structural equation modeling was used to examine potential gender differences in associations among exercise, weight loss behaviors, and alcohol use. Results: Critical ratio tests revealed that associations between exercise and weight loss behaviors were more strongly correlated among females as compared with males. For females, there was a small negative association between exercise and drinking behaviors; in contrast, for males, there was a …

The endogenous opioid system is involved in modulating a number of behavioral and physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. In humans, a functional variant in the OPRM1 gene (OPRM1 A118G) is associated with a number of outcomes, including attenuated HPA axis responses to stress. A nonsynonymous variant (OPRM1 C77G) in the rhesus macaque has been shown to have similar effects in vivo to the human variant. The current study investigated whether OPRM1 C77G influences HPA axis response to stress in rhesus macaques. We analyzed plasma adrenocorticotropic hormone (ACTH) and cortisol levels measured in response to three different stressors: 1) …
