Vobejda C, Fromme K, Samson W, and Zimmermann E
- Abstract
The aim of the present study was to investigate the accuracy of the maximal constant heart rate method for predicting anaerobic threshold (AnT) in running. This method only requires a common heart rate (HR) monitor and is based on the identification of the maximal constant HR maintainable for 30 min (HRMC). HRMC, 4-mmol threshold, and maximal lactate steady state (MLSS) were determined in 31 probands. 17 probands underwent an additional MLSS retest within 2 weeks. The correlation between HR at MLSS and at MLSS retest was very close (r = 0.807; SEE = 5.25 beats x min(-1); p < 0.001). So were the correlations between HR at 4-mmol threshold and MLSS (r = 0.844; SEE = 6.43 beats x min(-1); p < 0.001) and between HRMC and HR at MLSS (r = 0.820; SEE = 6.73 beats x min(-1); p < 0.001). Mean velocities at maximum constant HR trials and MLSS (r = 0.895; SEE = 0.185 m x s(-1); p < 0.001) as well as 4-mmol threshold and MLSS (r = 0.899; SEE = 0.186 m x s(-1); p < 0.001) were highly correlated. In conclusion, data presented in this study confirm that the determination of HRMC is a manageable method giving a highly accurate estimation of both HR and velocity at MLSS in running.

- Abstract
This article summarizes a symposium organized by Dr. Elizabeth D'Amico and presented at the 2004 Annual Meeting of the Research Society on Alcoholism in Vancouver, Canada. The four presentations illustrate the importance of creating substance use interventions that are developmentally appropriate for youth. They represent innovative approaches to working with preteens, teenagers, and young adults. Dr. D'Amico's paper describes her research on the development of a voluntary brief intervention targeting alcohol use among middle school students. Findings indicated that by using school and community input, she was able to obtain a diverse a sample of youth across grades, sex, ethnicity, and substance use status. Dr. Ellickson's paper describes her research on Project ALERT, a school-based prevention program for middle school youth. Her findings indicate that Project ALERT worked for students at all levels of risk (low, moderate, and high) and for all students combined. Dr. Wagner's Teen Intervention Project was a randomized clinical trial to test the efficacy of a standardized Student Assistance Program for treating middle and high school students with alcohol and other drug problems. The study provided a unique opportunity to begin to examine how development may impact response to an alcohol or other drug intervention. Dr. Turrisi's paper examined processes underlying the nature of the effects of a parent intervention on college student drinking tendencies. Findings suggested that the parent intervention seems to have its impact on student drinking by reducing the influence of negative communications and decreasing the susceptibility of influences from closest friends. Dr. Kim Fromme provided concluding remarks. [ABSTRACT FROM AUTHOR]

- Abstract
This article summarizes a symposium that was organized by Dr. Kim Fromme and presented at the 2003 annual meeting of the Research Society on Alcoholism in Ft. Lauderdale, Florida. The four presentations illustrate the emerging technologies and methods that are now being used to investigate the genetic basis of differential sensitivity to alcohol and their behavioral manifestations. Combining human genotyping with laboratory measures of behavior and subjective reports, these presentations represent state-of-the-art approaches to crossing the bridge from the Decade of the Brain to the Decade of Behavior. Dr. De Wit's paper describes her research on the neurobiological basis for individual differences in sensitivity to the stimulant and sedative effects of alcohol. Evidence suggests that activity of the dopaminergic and GABAergic neurotransmitters underlie these stimulant and sedative effects, respectively. Both Drs. Hutchison's and Corbin's papers describe their research on polymorphisms for the serotonin transporter (SLC6A4) as a determinant of the subjective effects of alcohol challenge. Dr. Hutchinson's and Ms. Ray's findings indicate that individuals with the short form of the SLC6A4 alleles (S) demonstrated a low level of response to alcohol, thus supporting previous research that the S allele may be associated with increased risk for alcohol dependence. In contrast, Dr. Corbin did not find a reliable association between the SLC6A4 genotype and subjective response to alcohol. Mr. Cook's and Dr. Wall's paper adds another dimension to this article by presenting research on both the aldehyde dehydrogenase (ALDH2) and alcohol dehydrogenase (ADH2) genetic variants and their association with the alcohol-related flushing response that is prevalent in Asian populations. Dr. David Goldman provides concluding remarks. [ABSTRACT FROM AUTHOR]

24. Heavy episodic drinking and college entrance.
- Author

Hartzler B and Fromme K
- Abstract
The college environment appears to encourage heavy drinking. Consequently, correlates of student drinking were assessed at college entrance. First-semester freshmen (N = 520, 54 percent women) completed self-report measures of social affiliation and self/peer drinking for high school and college. Analyses indicated that: 1) increased drinking at college entrance mirrored perceived increases by peers, 2) perceptions of peer drinking were robustly overestimated with women displaying the larger overestimation bias; and 3) social affiliation was associated with men's drinking and moderated its relation to perceived peer drinking at college entrance. These results advance understanding of the manner in which heavy drinking patterns emerge as men and women enter college, and campus programs that consider these factors may better promote health and reduce the harms associated with heavy drinking among college students.

- Abstract
Objective: We evaluated selection and socialization processes associated with perceived descriptive norms and drinking from high school through the first 2 years of college.Method: Participants (n = 2,247; 61.6% female) completed measures of high school drinking and descriptive drinking norms for their social group and the typical student at the university they were entering, as well as alcohol use and social-group norms through their sophomore year of college. We conducted structural equation models by gender and ethnicity to test high school drinking and drinking norms as predictors of collegiate drinking and social-group norms.Results: Perceptions of typical-college-student drinking during high school predicted freshman-year drinking for men but not women and for White but not Asian or Hispanic students. High school social-group norms predicted freshman drinking for White but not Asian or Hispanic students, whereas freshman social-group norms predicted sophomore drinking for all participants.Conclusions: Selection and socialization processes co-occur during this transitional time. Heavy drinkers in high school who perceive their friends to be heavy drinkers select into college social groups with perceived heavy drinking. Men and White students who perceive heavy drinking by the typical college student tend to drink heavily in college and choose social groups with perceived heavy drinking. These results support the importance of interventions that are tailored to the individual and that target perceptions of typical-college-student and social-group drinking before entering college for Whites and men but after matriculation for women, Asian, and Hispanic students.

- Abstract
Bipolar disorder co-occurs with alcohol use disorder at a rate 3-5 times higher than the general population. We recently reported that individuals with bipolar disorder differ in the positive stimulating and anxiolytic effects of alcohol compared with healthy peers. This study used a randomized, placebo-controlled, cross-over, within-subject alcohol administration design to investigate neurobiological mechanisms within ventral prefrontal cortical (vPFC) systems that may underlie altered sensitivity to alcohol in bipolar disorder (NCT04063384). Forty-seven young adults (n = 23 with bipolar disorder, 64% women) completed clinical assessment and two beverage administration sessions (alcohol and placebo, counter-balanced). Participants were dosed to 0.08 g% breath alcohol concentration during the alcohol condition and completed measures of subjective response to alcohol and an emotional processing fMRI task during the ascending limb. Timing during the placebo condition mirrored the alcohol session. Acute alcohol was associated with reduced functional connectivity between the insula - subcallosal cingulate cortex, and increased connectivity between the left nucleus accumbens - ventromedial PFC in bipolar disorder, but with no change in functional connectivity between these regions in healthy peers. Alcohol-related increases in nucleus accumbens - ventromedial PFC functional connectivity was associated with greater positive stimulating effects of alcohol in bipolar disorder and heavier recent alcohol use. Results suggest vPFC brain systems respond differently to acute alcohol during emotional processing in young adults with bipolar disorder compared with healthy peers, and that vPFC system responses relate to the subjective experience of intoxication and recent alcohol use., (© 2023.

- Abstract
Early life stress, specifically childhood maltreatment, and parental risk for mood and substance use disorders (SUDs) are associated with increased risk for alcohol use disorder (AUD). There is limited data on how these factors interact to contribute to alcohol-related outcomes. Prior work has suggested early life stress may increase sensitivity to psychostimulants and that subjective response to alcohol is heritable. It is unclear if early life stress alters sensitivity to alcohol and interacts with parental risk for mood/SUDs, which in turn may act as a risk factor for AUD. The current study uses within-subjects placebo-controlled alcohol administration methods to investigate the effects of childhood maltreatment on subjective response to alcohol in young adults with and without parental risk of mood/SUDs. Additionally, we explored interactions with drinking context (i.e., drinking in a bar vs. non-bar context). Within individuals with parental risk for mood/SUDs, there was a positive relation between total Childhood Trauma Questionnaire (CTQ) score and how drunk individuals reported feeling across both alcohol and placebo conditions (parental risk group-by-CTQ interaction p = .01; main effect of CTQ within individuals with parental risk for mood/SUDs p = .005). When exploring interactions with drinking context (bar vs. non-bar context), we observed a significant drinking context-by-parental risk-by-CTQ interaction (p = .03), with CTQ score positively associated with greater positive valence/positive arousal feelings in the parental risk group if they consumed their beverages in the bar context (p = .004) but not if they consumed their beverages in the non-bar context. Results suggest childhood maltreatment may contribute to variation in subjective response to the positive effects of alcohol-possibly mediated by alcohol cues and/or expectancies-in young adults with parental risk for mood/SUDs., Competing Interests: Declaration of competing interest We do not believe this relationship could influence the reported results, but we report them for transparency.

- Abstract
Limited data exists on mechanisms contributing to elevated risk for alcohol use disorder (AUD) in bipolar disorder. Variation in subjective response to alcohol may relate to alcohol use and risk for AUD. This study used a randomized, placebo-controlled, cross-over, within-subjects design to investigate differences in subjective response to alcohol in 50 euthymic young adults (n = 24 with and n = 26 without bipolar disorder type I). Eighty-three percent of participants with bipolar disorder were medicated. Participants completed assessments of clinical history, alcohol expectancies, and recent alcohol use. Participants were dosed to a .08 g% breath alcohol concentration. The placebo condition occurred on a separate counter-balanced day. Subjective response to alcohol was investigated at similar time points during both conditions. Group, condition, and group-by-condition interactions were modeled, with condition and time of subjective response assessment as repeated within-subject variables, and subjective response to alcohol as the dependent variable. Greater stimulating effects and liking of alcohol were reported in people with bipolar disorder (group-by-condition interactions, p < .05) than healthy young adults. While young adults with bipolar disorder reported anticipating feeling less "mellow/relaxed" when drinking (p = .02), during both beverage conditions they reported feeling more "mellow/relaxed" (main effect of group, p = .006). Feeling more "mellow/relaxed" during the alcohol condition related to greater recent alcohol use in bipolar disorder (p = .001). Exploratory analyses suggested anticonvulsants and sedatives/antihistamines may relate to differences in subjective response to alcohol in bipolar disorder. Results suggest young adults with bipolar disorder may differ in alcohol expectancies and experience alcohol intoxication differently-with distinct relations between subjective response to alcohol and alcohol use-compared to healthy young adults., (© 2023.

- Abstract
Objective: College athletes are a high-risk group for heavy drinking and related risky behaviors and consequences. However, most prior work examining drinking behavior in college athletes has been cross-sectional. Drinking norms predict drinking among athletes, but other potential risk factors, including personality traits have received limited attention., Method: Using data from a large sample ( n = 2,245) of college students, we examined athletic participation, high-risk personality traits (i.e., impulsivity, sensation seeking), and perceptions of peer drinking behavior (descriptive and injunctive norms) as predictors of binge drinking from prior to college entry through 2 years postcollege. Negative binomial latent growth models were used to examine these predictors of patterns of drinking across the college years., Results: Binge drinking increased through the first 3 years of college before leveling off and decreasing postcollege. Controlling for significant effects of sensation seeking and perceptions of peer attitudes and drinking behaviors, athletic participation at T1 was associated with greater binge drinking at matriculation and greater athletic participation was associated with greater risk across the college years. Normative perceptions and sensation seeking also predicted concurrent drinking in Year 4 of college and impulsivity emerged as an additional predictor. Sensation seeking emerged as a significant predictor of greater postcollege binge drinking. Athletic participation in Year 4 of college indicated no significant risk for greater binge drinking during Year 4 or following graduation., Conclusions: Early participation in competitive athletics was associated with risk for binge drinking, even when accounting for several social and personality factors. Future studies using momentary assessment may be fruitful for identifying within-subject pathways of risk, including athlete specific factors.

- Abstract
Background: Rates of alcohol use disorders in individuals with bipolar disorder are 3 to 5 times greater than in the general population and exceed rates of alcohol use disorders reported in other affective and anxiety disorders. Despite this high rate of comorbidity, our understanding of the psychosocial and neural mechanisms that underlie the initiation of alcohol misuse in young adults with bipolar disorder remains limited. Prior work suggests that individuals with bipolar disorder may misuse alcohol as a coping mechanism, yet the neural correlates of coping drinking motives and associated alcohol use have not been previously investigated in this population., Methods: Forty-eight young adults (22 bipolar disorder type I, 26 typically developing; 71% women; average age ± standard deviation = 22 ± 2 years) completed the Drinking Motives and Daily Drinking Questionnaires, and a Continuous Performance Functional magnetic resonance imaging (fMRI) Task with Emotional and Neutral Distracters. We calculated the relative difference in anterior cingulate cortex (ACC) functional coupling with the anterior insula and amygdala in response to emotional distracters compared with neutral stimuli and investigated the relations with coping drinking motives and alcohol use., Results: Across all participants, coping drinking motives were associated with greater quantity of recent alcohol use. In individuals with bipolar disorder, greater ACC-anterior insula functional coupling was associated with greater coping drinking motives, and greater quantity and frequency of recent alcohol use. The relative difference in ACC-anterior insula functional coupling was not associated with coping drinking motives or alcohol use in the typically developing group. Greater ACC-anterior insula functional coupling in individuals with bipolar disorder was also associated with greater anxiety symptoms and recent perceived psychological stress. Exploratory analyses suggest that the relations between ACC-anterior insula functional coupling and coping drinking motives may be confounded by anticonvulsant use., Conclusion: Results suggest that a difference in ACC-anterior insula functional coupling during emotion processing may underlie alcohol use as a maladaptive coping mechanism in young adults with bipolar disorder., (© 2022 Research Society on Alcoholism.)

- Abstract
(1) Background: Alcohol use in the course of mood disorders is associated with worse clinical outcomes. The mechanisms by which alcohol use alters the course of illness are unclear but may relate to prefrontal cortical (PFC) sensitivity to alcohol. We investigated associations between alcohol use and PFC structural trajectories in young adults with a mood disorder compared to typically developing peers. (2) Methods: 41 young adults (24 with a mood disorder, agemean = 21 ± 2 years) completed clinical evaluations, assessment of alcohol use, and two structural MRI scans approximately one year apart. Freesurfer was used to segment PFC regions of interest (ROIs) (anterior cingulate, orbitofrontal cortex, and frontal pole). Effects of group, alcohol use, time, and interactions among these variables on PFC ROIs at baseline and follow-up were modeled. Associations were examined between alcohol use and longitudinal changes in PFC ROIs with prospective mood. (3) Results: Greater alcohol use was prospectively associated with decreased frontal pole volume in participants with a mood disorder, but not typically developing comparison participants (time-by-group-by-alcohol interaction; p = 0.007); however, this interaction became a statistical trend in a sensitivity analysis excluding one outlier in terms of alcohol use. Greater alcohol use and a decrease in frontal pole volume related to longer duration of major depression during follow-up (p’s < 0.05). (4) Conclusion: Preliminary findings support more research on alcohol use, PFC trajectories, and depression recurrence in young adults with a mood disorder including individuals with heavier drinking patterns.

- Abstract
Objective: The current project aims to enhance our understanding of the well-established relation between fraternity membership and sexual aggression on college campuses. Most prior research has been cross-sectional and unable to distinguish selection and socialization accounts of the relation, and only one prior longitudinal study has simultaneously examined selection and socialization effects., Method: Fraternity membership, sexual aggression, binge drinking, sociosexual attitudes and behaviors, and perceived peer sexual aggression were assessed for 772 male participants ( n = 116 fraternity members) in a longitudinal survey study from the summer prior to college through Year 2 of college., Results: Longitudinal path analyses revealed three key findings. First, fraternity membership was prospectively correlated with sexual aggression in Years 1 and 2 of college (socialization effect), controlling for selection effects, when the two prospective paths were constrained to be equivalent. Second, more frequent binge drinking and sociosexual attitudes prior to college prospectively correlated with an increased likelihood of joining a fraternity (selection effect), and both selection variables indirectly correlated with future sexual aggression via fraternity membership. Third, fraternity membership was associated with increased binge drinking and perceived peer sexual aggression (socialization effects)., Conclusions: These findings identify critical targets for the prevention of sexually aggressive behavior that are linked to fraternity membership: Binge drinking and sociosexual attitudes.

- Abstract
Prior research demonstrates contextual influences on drug responses in both animals and humans, although studies in humans typically focus on only one aspect of context (e.g., social) and examine a limited range of subjective experiences. The current study sought to address these limitations by examining the impact of both social and physical context on the full range of subjective alcohol effects. The sample included 448 young adult social drinkers (57% male, 66.5% White) randomly assigned to consume alcohol (target blood alcohol concentration of .08 g%) or placebo in 1 of 4 contexts (solitary lab, group lab, solitary bar, group bar). Results indicated that high arousal positive (HAP) effects of alcohol (e.g., talkative, lively) were stronger in nonbar relative to bar contexts and that low arousal positive (LAP) effects (e.g., relaxed, calm) were only present in the group lab context. There were also main effects of social context such that high arousal effects (both positive and negative) were stronger in group contexts, regardless of beverage condition. These findings highlight the importance of considering context when examining alcohol effects. Studies designed to isolate pharmacological HAP effects may benefit from a nonbar setting, and studies of LAP effects might be most effective in a simulated living room or home environment, although future studies are needed to directly address this possibility. Further, studies with an explicit focus on expectancies or that need strong control for expectancies might benefit from a group context, particularly when studying high arousal effects.

- Abstract
There are startling rates of sexual coercion across college campuses, underscoring the importance of identifying risk factors and intervening early to prevent perpetration of these unwanted sexual events. The aim of this study was to examine the effects of impulsivity, sensation seeking, and alcohol use on the odds of perpetrating unwanted sexual advances (i.e., forced fondling, kissing, or petting) and sexual coercion (i.e., sexual intercourse through arguments, pressure, or physical force) during the subsequent 6 years. Male participants ( N = 901) were part of a 6-year longitudinal study, which explored alcohol use and associated behavioral risks throughout emerging adulthood. Participants provided self-reported surveys across 6 years, starting the summer before their start of college. Using logistic regression models, these analyses examined the main effects and interactions of impulsivity, sensation seeking, and alcohol use, measured during the summer before the start of college, on the odds of perpetrating one or multiple instances of unwanted sexual advances and sexual coercion across the subsequent 6 years. Results indicated that higher levels of sensation seeking and heavier drinking on drinking days during high school contributed to greater odds of being a one-time perpetrator of unwanted sexual advances during the next 6 years. Conversely, impulsivity, but not alcohol use, was associated with greater risk of perpetrating multiple instances of both unwanted sexual advances and sexual coercion. Alcohol use did not significantly moderate the influence of personality on perpetration. These results underscore the importance of early intervention and using impulsivity and sensation seeking to tailor current prevention efforts to decrease the likelihood of sexual coercion perpetration during college.

- Abstract
Background: Alcohol use disorders (AUDs) are highly prevalent in bipolar disorder, however the developmental etiology of this comorbidity remains unknown. Structural differences in the orbitofrontal cortex (OFC) have been linked to problematic drinking in bipolar disorder and typically developing youth, with evidence implicating variations in OFC in differential subjective response to alcohol in typical development., Methods: Subjective response to alcohol, recent alcohol use, impulsivity, and variation in OFC gray matter volume were investigated in 48 emerging adults (24 with bipolar disorder, 24 typically developing). On average 1.5 years later, drinking patterns were reassessed and relations between subjective response and changes in alcohol use were explored., Results: Groups did not differ in baseline alcohol use or subjective response. At baseline, decreased subjective response to alcohol was associated with increased alcohol use in both groups. Lower gray matter volume in medial OFC in bipolar disorder was associated with increased subjective response to alcohol, whereas lower gray matter volume in OFC in typically developing participants was associated with decreased subjective response to alcohol. Increase in alcohol use (baseline to follow-up) was associated with increased baseline subjective response to alcohol in bipolar disorder, and decreased baseline subjective response in the typically developing group., Limitations: Preliminary study with a small sample size., Conclusion: Underlying OFC biology may contribute to differences in alcohol sensitivity in bipolar disorder which may also relate to prospective changes in alcohol use patterns. Future studies are needed to examine how these factors prospectively relate to development of AUDs in bipolar disorder., (Copyright © 2020. Published by Elsevier B.V.)

- Abstract
Childhood maltreatment is associated with adverse effects on the brain, and an increased risk for psychopathology, including mood and substance use disorders. Individuals vary on the degree to which they exhibit neurobiological and clinical differences following maltreatment. Individuals with bipolar disorder exhibit greater magnitude of maltreatment-related prefrontal-paralimbic gray matter volume (GMV) deficits compared to typically developing individuals. It is unclear if greater structural differences stem from greater neural vulnerability to maltreatment in bipolar disorder, or if they relate to presence of other clinical features associated with childhood maltreatment, e.g., elevated prevalence of comorbid substance use disorders. To investigate this, we compared young adults with a family history of bipolar disorder (n = 21), but who did not fulfill diagnostic criteria for bipolar disorder, with typically developing young adults without a family history of bipolar disorder (n = 26). Participants completed structural neuroimaging, clinical and family history interviews, and assessment of childhood maltreatment and recent alcohol and cannabis use patterns. We examined relations between childhood maltreatment and prefrontal-paralimbic GMV by modeling main effects of maltreatment and family history group by maltreatment interactions on prefrontal-paralimbic GMV. We also examined relations between maltreatment and associated GMV changes with recent alcohol and cannabis use. Childhood maltreatment correlated with lower ventral, rostral and dorsolateral prefrontal and insular cortical GMV across all participants regardless of the presence or absence of familial history of bipolar disorder. However, exploratory analyses did reveal greater maltreatment-related GMV differences in individuals with prodromal symptoms of depression. Lower insula GMV was associated with greater frequency of cannabis use across all participants and greater quantity of alcohol use only in those with familial risk for bipolar disorder. Results suggest familial risk for bipolar disorder, and presumably genetic risk, may relate to outcomes following childhood maltreatment and should be considered in prevention/early intervention strategies.

- Abstract
Dating violence presents a serious threat for individual health and well-being. A growing body of literature suggests that starting in adolescence, individuals with sexual minority identities (e.g., individuals who identify as gay, lesbian, or bisexual) may be at an increased risk for dating violence compared with heterosexuals. Research has not, however, identified the mechanisms that explain this vulnerability. Using a diverse sample of young adults ( n = 2,474), the current study explored how minority stress theory, revictimization theory, sex of sexual partners, and risky sexual behavior explained differences in dating violence between sexual minority and heterosexual young adults. Initial analyses suggested higher rates of dating violence among individuals who identified as bisexual, and individuals who identified as gay or lesbian when compared with heterosexuals, and further found that these associations failed to differ across gender. When mediating and control variables were included in the analyses, however, the association between both sexual minority identities and higher levels of dating violence became nonsignificant. Of particular interest was the role of discrimination, which mediated the association between bisexual identity and dating violence. Other factors, including sex and number of sexual partners, alcohol use, and childhood maltreatment, were associated with higher rates of dating violence but did not significantly explain vulnerability among sexual minority individuals compared with their heterosexual peers. These findings suggest the importance of minority stress theory in explaining vulnerability to dating violence victimization among bisexuals in particular, and generally support the importance of sexual-minority specific variables in understanding risk for dating violence within this vulnerable population.

- Abstract
The present study examined the acute effect of alcohol and its cues on autonomic and cardiovascular physiology, as indexed by changes in heart rate (HR), in a relatively large sample of healthy young adult men and women. Participants (27-31 years old, final N = 145) were administered an alcoholic beverage ( n = 88; 52 women) or a placebo beverage ( n = 57; 35 women) in a simulated bar. Target breath alcohol concentration (BrAC) was .08 g%. HR was recorded while participants were seated alone during an initial baseline assessment in a lab room; seated with others during preparation and administration of 2 beverages in a simulated bar; and seated alone in the lab room at ascending, peak, and descending BrAC. HR increased over time for participants in both beverage groups during beverage preparation. During beverage consumption, HR decreased over time in those who drank placebo whereas HR increased over time in those who drank alcohol, increasing at a faster rate in women compared to men. HR remained elevated at the ascending, peak, and descending limb assessments only in participants who drank alcohol with HR increasing over time at ascending BrAC in the women but not men. Sex differences in HR under alcohol were not explained by sex differences in body mass index, BrAC, recent alcohol use, or subjective stimulation. Our findings suggest that women may be more sensitive to alcohol-induced increases in HR, especially in environments where alcohol cues are abundant. This may have implications for cardiovascular risks associated with alcohol. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

- Abstract
Objective: The beginning of college is a period in which increased alcohol use often coincides with greater involvement in romantic relationships. Existing literature yields inconsistent findings regarding the influence of relationship types on drinking behavior, perhaps because these studies have not accounted for recent changes in the way college students engage in dating/sexual relationships., Methods: The present study sought to address this issue using a longitudinal study design by examining the effects of both relationship type and sexual activity on heavy episodic drinking (HED) among 1,847 college students over the course of the first 3 semesters of college., Results: Results indicated that the effects of relationship type depended on whether an individual was sexually active. Nondating but sexually active students reported rates of HED comparable to students who defined themselves as casual daters. Conversely, nondating students who were not sexually active reported drinking behavior similar to those involved in exclusive relationships. Further, transitions between low- and high-risk relationship/sexual activity types were associated with corresponding changes in HED. Transitioning into a high-risk relationship was associated with significant increases in levels of HED, whereas transitioning into a low-risk relationship was associated with significant decreases in HED., Conclusions: Together, results indicate that engaging in nonexclusive dating or casual sexual relationships may play an important role in the development of problematic patterns of alcohol use during the early college years. These findings have potentially important implications both for future research and for prevention and intervention efforts targeting high-risk college drinkers., (© 2020 by the Research Society on Alcoholism.)

- Abstract
Research indicates that lesbian, gay, and bisexual (LGB) youth are at increased risk for heavy drinking relative to their heterosexual peers. One possible contributing factor is that religiosity fails to provide the significant protection for LGB youth that it provides in general population samples. Although prior studies provide some support for this hypothesis, there is little research on the reasons that religiosity may fail to protect against heavy drinking among LGB youth. The current study addressed this question by examining relations among religiosity, age of self-identification as LGB, and alcohol use in a sample of 162 young adults self-identified as lesbian, gay, bisexual, or questioning. Age of self-identification was conceptualized as an indicator of stress or internal conflict between religious beliefs and self-identification. We hypothesized that higher levels of religiosity would be associated with a later age of identification as LGB, which, in turn, would contribute to heavier drinking. Path analyses conducted in Mplus provided support for this hypothesis, with higher levels of religiosity indirectly contributing to increased alcohol use through later age of self-identification. Whereas additional studies directly assessing stress associated with the self-identification process are needed, the results of this study suggest that religiosity may serve as a risk, rather than protective, factor among LGB youth. The development of religious support groups specifically for LGB youth may help these individuals reconcile their religious beliefs with their emerging sexual identities, thereby allowing them to derive some of the same benefits that heterosexual youth derive from religious beliefs and practices.

- Abstract
Background: Emerging adulthood is a peak period of risk for alcohol and illicit drug use. Recent advances in psychiatric genetics suggest that the co-occurrence of substance use and psychopathology arises, in part, from a shared genetic etiology. We sought to extend this research by investigating the influence of genetic risk for schizophrenia on trajectories of four substance use behaviors as they occurred across emerging adulthood., Method: Young adult participants of non-Hispanic European descent provided DNA samples and completed daily reports of substance use for 1 month per year across 4 years (N = 30 085 observations of N = 342 participants). A schizophrenia polygenic score was included in two-level hierarchical linear models designed to test associations between genetic risk for schizophrenia, participant age, and four substance use phenotypes., Results: Participants with a greater schizophrenia polygenic score experienced greater age-related increases in the likelihood of using substances across emerging adulthood (p < 0.005). Additionally, our results suggest that the polygenic score was positively associated with participants' overall likelihood to engage in illicit drug use but not alcohol-related substance use., Conclusions: This study used a novel combination of polygenic prediction and intensive longitudinal methods to characterize the influence of genetic risk for schizophrenia on patterns of age-related change in substance use across emerging adulthood. Results suggest that genetic risk for schizophrenia has developmentally specific effects on substance use behaviors in a non-clinical population of young adults.

- Abstract
The development of online dating has created a cultural shift in how emerging adults approach dating. The present study examined retrospective and event-level associations between alcohol, online dating, and sexual hookups among a sample of single, postcollege women. Participants completed baseline and 24 electronic daily diary surveys on alcohol use, sexual behavior, and method for meeting their sexual partners. We examined the influence of alcohol on sexual hookups, and how method of meeting a partner, and location prior to the hookup influenced level of intoxication during a sexual hookup. There was a within-person effect of alcohol on likelihood of engaging in a sexual hookup whereby hookups were more likely on days when women reported higher levels of intoxication relative to their average drinking. Spending time at bar/party prior to a sexual hookup was associated with higher levels of intoxication prior to a sexual hookup relative to being at other locations. Measured in the daily diary surveys, meeting a sexual hookup partner online was associated with lower levels of intoxication during the hookup relative to when meeting at bars/parties, even when including location just prior to the hookup in the model. The baseline retrospective analyses also indicated that meeting a partner online was associated with drinking less frequently before a sexual hookup relative to meeting a partner at a bar/party. Interventions to address alcohol use, method for meeting a partner, and location prior to hookups could be effective in decreasing potential negative consequences of alcohol-related sexual behavior in emerging adult women.

- Abstract
Sexual assault is a troubling epidemic that plagues college campuses across the United States, and is often proceeded by drinking by the perpetrator and/or victim. The goal of this study was to examine the effect of level of intoxication, history of alcohol-related blackouts, and childhood sexual abuse (CSA) on the likelihood of being a victim or perpetrator of coercive sexual activities. Participants (N = 2,244) were part of a 6-year longitudinal study which explored alcohol use and associated behavioral risks during college. A subsample (N = 1,423) completed 30 days of daily diary surveys across four years of college. Participants provided daily reports of their alcohol consumption, sexual coercion perpetration, and sexual coercion victimization. Using hierarchical linear models, results indicated that increases in daily estimated blood alcohol concentration (eBAC) were associated with a greater likelihood of being a victim and a perpetrator of sexual coercion. In addition, main effects of CSA and history of blackouts predicted a greater likelihood of being coerced into sexual activity, but blackouts were not associated with being a perpetrator. A significant interaction between blackouts and event-level eBAC indicated that individuals with a history of blackouts had a greater likelihood of sexual coercion victimization relative to those without prior blackouts. Finally, having a history of blackouts and CSA was predictive of a lower likelihood of being a perpetrator of sexual coercion at higher eBACs relative to those without a history of blackouts. Thus, prevention efforts should integrate the impact of blackouts and CSA on sexual coercion victimization and perpetration. (PsycINFO Database Record, ((c) 2018 APA, all rights reserved).)

- Abstract
Objective: We prospectively examined whether subjective intoxication serves as a risk factor for experiencing alcohol-induced blackouts. We then examined whether subjective intoxication and/or blackouts predicted motivation to decrease their drinking, and whether this motivation to change would promote future changes in drinking behavior., Method: Participants (N=1854, 62.1% female, 53.2% Caucasian, M
age =21.8) were recruited the summer prior to matriculating into a large, public university to complete a 6-year longitudinal study. Self-reported motivation to decrease their drinking behavior, their frequency of blackouts, quantity of alcohol consumption, and subjective intoxication (i.e., feeling drunk) were assessed annually during the transition out of college (Years 4-6)., Results: In a cross-lagged model, subjective intoxication (i.e., feeling drunk) prospectively predicted experiencing blackouts (p<0.001). Controlling for both objective (e.g., quantity) and subjective intoxication, blackouts at Year 4 predicted greater motivation to decrease drinking behavior at Year 5 (p<0.01), but this motivation did not predict less quantity of alcohol use by Year 6 (p=0.076)., Conclusions: Subjective intoxication is a robust predictor of blackouts across time. Additionally, blackouts are modest, developmentally-limited predictors of motivation to change drinking behavior, but blackouts do not predict future behavior change., (Copyright © 2018 Elsevier Ltd.

- Abstract
GABRA2, the gene encoding the α2 subunit of the GABAA receptor, potentially plays a role in the etiology of problematic drinking, as GABRA2 genotype has been associated with subjective response to alcohol and other alcohol-related reward processes. The GABRA2 gene has also been associated with illicit drug use, but the extent to which associations with drug use are independent of associations with alcohol use remains unclear, partly because most previous research has used a cross-sectional design that cannot discriminate comorbidity at the between-person level and co-occurrence within-persons. The present study used a daily monitoring method that assessed the effects of GABRA2 variation on substance use as it occurred in the natural environment during emerging adulthood. Non-Hispanic European participants provided DNA samples and completed daily reports of alcohol and drug use for 1 month per year across 4 years (N = 28,263 unique observations of N = 318 participants). GABRA2 variants were associated with illicit drug use in both sober and intoxicated conditions. Moreover, the effect of GABRA2 variation on drug use was moderated by an individual's degree of intoxication. These findings are consistent with recent genetic and neuroscience research, and they suggest GABRA2 variation influences drug-seeking behavior through both alcohol-related and alcohol-independent pathways.

- Abstract
Objective: Previous studies have found preliminary evidence for associations between common single-nucleotide polymorphisms (SNPs) in the cannabinoid receptor gene CNR1 and cannabis use and dependence. The present study examined a set of eight independent SNPs in or near CNR1 in relation to cannabis use measured longitudinally across emerging adulthood., Method: Using latent growth curve modeling of 10 waves of longitudinal data spanning mean ages 18.4-23.8 years in a sample of non-Hispanic White individuals (n = 334), we tested if genotype at each CNR1 SNP was associated with both level and growth of cannabis use over time. Peer group drug use, a known correlate of individual use, was evaluated as a time-varying predictor of cannabis use and as a moderator of the relationship between SNPs and individual use., Results: After correction for multiple comparisons, one SNP, rs806374, was significantly associated with individual differences in level-but not growth-of cannabis use over time, such that C carriers were more likely to use cannabis more frequently at study onset (around age 18). Peer drug use was a predictor of individual cannabis use that grew in terms of effect size with time, but did not significantly moderate the effect of rs806374 genotype., Conclusions: C carriers at rs806374 may be at specific risk for increased odds of use during the transition out of high school (around age 18). Future studies should investigate potential mechanisms at this developmental stage, including individual differences in subjective response, innate tolerance, reinforcement mechanisms, or general liability for substance misuse.

- Abstract
Objective: This study examined how freshman year substance use prospectively predicted time to college graduation, and whether delayed graduation predicted postponed adoption of adult roles and future substance use., Participants: Participants were part of a longitudinal study that began in 2004. The first analyses focused on freshman year (N = 2,050). The second analyses corresponded to a subset of participants at age 27 (N = 575)., Methods: Measures included self-reported substance use, adult role adoption, and university reported graduation dates., Results: Results indicated that frequent binge drinking and marijuana use during freshman year predicted delayed college graduation. Those who took longer to graduate were more likely to have lower incomes and were less likely to obtain a graduate degree. Taking 5-6 years to graduate was associated with greater likelihood of alcohol-related problems., Conclusions: Findings support the importance of interventions during freshman year of college to decrease substance use and promote timely graduation.
