Denial, Attention-Seeking, and Posting Online While Intoxicated: Three Key Predictors of Collegiate Sadfishing.

Sadfishing, or the exaggeration of one's emotional state online to generate sympathy, is a maladaptive behavior that can negatively affect mental health. A better understanding of the characteristics of individuals who sadfish could inform tailored interventions to decrease sadfishing and improve quality of life. However, to date, the phenomenon of sadfishing remains understudied. Thus, the current project was designed to identify some of the key psychological and behavioral characteristics that may be associated with sadfishing. Undergraduate college students (N = 374) recruited from introductory psychology courses at a large, Hispanic-serving institution completed an anonymous online survey assessing sadfishing and other online behaviors, psychological characteristics (coping, stress, resilience, and social support), and alcohol use. Both univariate and multivariate statistical analyses were conducted. Results of the binary logistic regression analysis found that students who reported using denial as a coping strategy (p = 0.005), who endorsed the attention-seeking behaviors associated with histrionic personality disorder (p = 0.021), and who used social media while intoxicated (p = 0.017) were most likely to report sadfishing. This study furthers our knowledge of the maladaptive online behavior of sadfishing and identifies several key predictors that could become targets for tailored interventions. In particular, our results highlight the importance of coping skills training for individuals who sadfish.

The Influence of Adverse Childhood Experiences on Malevolent Creativity in Young Adulthood.

BACKGROUND: Childhood trauma may increase the risk of antisocial behavior in young adulthood. Our study examined the relationship between Adverse Childhood Experiences (ACEs) and the specific antisocial behavior of malevolent creativity (MC), the application of original ideas to purposely harm others, often to gain an unfair advantage through manipulation, threat, or harm. METHODS: We surveyed college students (N = 524; 78% women) on demographics, ACEs, empathy, social support, coping, general creativity, and malevolent creativity. The data were analyzed via sequential linear regression models. RESULTS: Reporting ≥ 4 ACEs was associated with increased MC, which remained significant when general creativity and demographics were controlled. The association between higher ACEs and MC was no longer significant when psychosocial control variables (social support, empathy, and coping) were included in the statistical model. Social support and empathy were negatively associated with MC, while coping and MC were positively associated. CONCLUSIONS: ACEs may increase the likelihood of malevolent creativity in young adulthood, but empathy and social support may disrupt this trajectory. Care should be taken that coping skills, while typically viewed as a positive addition to one's behavioral repertoire, do not push individuals toward over-reliance on themselves, which may reduce prosocial behaviors and increase MC.

Blackouts and hangover experiences among Hispanic and Non-Hispanic White college students.

Blackouts and hangovers may negatively impact college students' health and productivity. However, few studies have considered the impact of cultural differences on students' individual experiences with blackouts and hangovers. To address this issue, the current study explored the potential relationships of shame and resilience with Hispanic (n = 381) and non-Hispanic White (NHW, n = 332) students' self-reported blackouts and hangover experiences. Students completed an online survey measuring shame, resilience, presence of lifetime blackout experiences preceding a hangover, and past-year hangover severity. Analyses included separate path models examining shame and resilience, and the interaction between shame and resilience with Hispanic ethnicity in relation to blackouts and hangover experiences. Significant pathways emerged between resilience, but not shame, and blackouts and hangover experiences. A subscale of resilience reflecting personal competence and tenacity was related to greater likelihood of reporting blackouts and greater hangover severity for Hispanics but not NHW students. Conversely, a dimension of resilience characterized by trusting one's instincts and tolerance of negative affect was related to a lower likelihood of reporting a blackout preceding a hangover for Hispanics but not NHW students. Finally, a resilience subscale associated with spiritual influences was positively related to blackouts in the participant population as a whole. These results reinforce the notion that resilience is an important target for intervention and prevention of hazardous drinking, but reveal that it may have both positive and negative effects in college students, which may differ by ethnicity.

Collegiate Binge Drinking and Social Media Use Among Hispanics and Non-Hispanics.

OBJECTIVE: College students' reliance on social media is both a risk factor for alcohol-related problems and a possible avenue for intervention. Greater understanding of students' social media habits in relation to drinking may lead to more effective prevention efforts. This study examined the use of alcohol and social media in Hispanic and non-Hispanic college students with and without a history of binge drinking. METHOD: Participants (N = 424; age 18-25; 84% female) completed online surveys of alcohol use, intensity of use for Snapchat, Instagram, Facebook, and Twitter, social media addiction, and retrospective frequency of social media use while drinking and after intoxication. RESULTS: Historical binge drinkers had greater intensity scores for Snapchat, Instagram, and Twitter, and were more likely to report using social media and alcohol concurrently, even while intoxicated (ps < .05). Compared with Hispanics, non-Hispanics exhibited greater intensity of use for Instagram (ps = .001). Quantity and frequency of alcohol use was positively correlated with intensity scores for Snapchat, Instagram and Twitter (ps < .001), as well as social media addiction (p < .001), and use of social media while drinking and after intoxication (ps < .001). Age at first alcohol use and first intoxication were negatively correlated with use of social media while drinking and after intoxication (ps < .001). CONCLUSIONS: The results of this study may inform intervention efforts aimed at curbing hazardous college drinking by highlighting a context in which students could be exposed to harm-reduction messages presented through social media.

Alcohol Preferences and Event-Related Potentials to Alcohol Images in College Students.

OBJECTIVE: Research on attentional biases to alcohol images has used heterogeneous sets of stimuli (e.g., an isolated beer can or a group of people drinking). However, alcoholic beverage preferences play an important part in determining an individual's alcohol use pattern and may influence attentional biases, especially for inexperienced drinkers. The current study examined whether alcoholic beverage preferences affect event-related potential (ERP) indices of cue reactivity to different types of alcohol images (e.g., beer, wine, and distilled spirits) in heavy episodic drinkers. METHOD: ERPs were recorded in 14 heavy episodic drinkers (7 male) who completed a Go/No-Go task using preferred and nonpreferred alcohol images with nonalcoholic beverage images as controls. RESULTS: Larger N2 amplitudes for preferred alcohol images were observed relative to control images and to nonpreferred alcohol images, indicating increased attentional capture by preferred beverages. P3 amplitudes and latencies were not sensitive to preferences, but latencies were delayed and amplitudes were enhanced on No-Go trials (i.e., trials requiring response inhibition). CONCLUSIONS: These results suggest that alcoholic beverage preference is a factor influencing alcohol cue reactivity in heavy-episodic-drinking college students. This information has methodological significance and may also be applied to improve treatment and prevention programs that focus on attentional bias modification and inhibitory control training.

Stress-induced change in serum BDNF is related to quantitative family history of alcohol use disorder and age at first alcohol use.

Previous research in animal models suggests that brain-derived neurotrophic factor (BDNF) is involved in stress-modulated alcohol consumption. However, relatively few studies have investigated this issue in humans, and results of existing studies have been heterogeneous. The primary aim of the current study was to examine the within-subjects effect of acute stress (timed math plus cold pressor) on serum BDNF levels (ΔBDNF: post- minus pre-stress) in healthy social drinkers (N=68, 20 male). A secondary aim was to explore which heritable and environmental factors in our limited sample might exert the greatest influences on ΔBDNF. Importantly, presence versus absence of the BDNF Val66Met polymorphism (rs6265), which has often been discounted in studies of human serum BDNF, was included as a between-subjects control variable in all statistical analyses. Our results indicated that acute stress decreased serum BDNF. Further, multiple regression analyses revealed that quantitative family history of alcohol use disorder (qFH) and age at first alcohol use together accounted for 15% of the variance in ΔBDNF. Thus, the influences of qFH and age at first alcohol use may explain some of the heterogeneity that exists in previous studies of human serum BDNF. These results parallel findings in animal models and suggest that stress-related changes in serum BDNF are influenced by both heritable (qFH) and environmental (early alcohol consumption) factors.

Stress, Immune Function and Collegiate Holiday Drinking: A Pilot Study.

BACKGROUND/AIMS: Social aspects of collegiate holiday drinking have been studied frequently, but physiological consequences are often overlooked. This study examined self-reported stress, endocrine and immune indicators in students at an American university before and after their week-long spring break (SB) holiday. METHODS: Participants (n = 27; 9 males) provided saliva samples and completed surveys pre- and post-SB. Based on their cortisol reaction to SB, participants were grouped as cortisol nonresponders (CNR; n = 14) or increasers (CI; n = 13). Groups were matched on demographics, baseline alcohol use, family history of alcoholism, and SB plans. Differences over time and between groups were examined for α-amylase, quantity/frequency of alcohol use (quantity/frequency index, QFI) and the immunoglobulin A (IgA) to albumin ratio (IgA:albumin). RESULTS: α-Amylase decreased over time. A time × group interaction was noted for QFI, in which CNRs increased drinking over SB, but CIs did not. Time and time × group effects occurred for IgA:albumin. CIs decreased IgA:albumin over SB, whereas CNRs did not. Pre-SB QFI and pre-/post-SB QFI changes were correlated with changes in IgA:albumin. CONCLUSION: These findings support previously published relationships between blunted cortisol responses and risk for problem drinking, as well as elevated cortisol and decreased immune response. These data also highlight the importance of physiological measures in the study of collegiate holiday drinking.

Neural and genetic correlates of binge drinking among college women.

Ninety-seven female students were assigned to groups consisting of 55 infrequent and 42 frequent binge drinkers. The groups were compared on self-report measures of impulsivity, sensation seeking, and alexithymia, as well as several measures relevant to neural and genetic mechanisms, such as brain activation during a time estimation task and selected genotypes. Analyses of stimulus-locked brain activity revealed a slow cortical potential over the right parietal cortex during time estimation that was more negative among frequent binge drinkers. This group also showed a greater prevalence of a CHRM2 genotype previously associated with substance dependence and Major Depressive Disorder as well as a modest elevation on a non-planning impulsiveness scale. We conclude that the enhanced brain activation shown by binge drinkers compensates for an underlying deficit. That deficit may be reflected in poor planning skills and a genetic difference indicating increased risk for problems in later life.

College drinking among Latinos(as) in the United States and Mexico.

BACKGROUND AND OBJECTIVES: Existing studies of Latino(a) college students in the United States suggest that self-reported alcohol consumption tends to be higher among males, and that drinking among Latinas is often influenced by social and contextual factors. The current study extended this work by examining both self-reported drinking levels and predictors of drinking among Latino(a) college students in the United States and Mexico (MX). METHODS: Latino(a) college students (N = 376) from three universities in the South Central United States and Northern Mexico completed pencil-and-paper surveys about alcohol. RESULTS: US Latino students (vs. MX males), reported drinking more frequently and had more positive expectancies about alcohol. Latinas in the United States (vs. MX females) were more likely to report regular drinking. Across countries, both female gender and the Mexican orientation component of acculturation predicted lower reported alcohol consumption. Positive expectancies about drinking predicted increased drinking. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Self-reported college drinking and expectancies about alcohol may differ subtly among individuals in the United States and Mexico based on gender and endorsement of traditional Mexican values. These findings could ultimately be applied to the development of more tailored programs for the treatment and prevention of alcohol abuse on college campuses.

Acute stress and event-related potential correlates of attention to alcohol images in social drinkers.

OBJECTIVE: The use of alcohol to cope with stress is a major health concern, yet the neurophysiological mechanisms underlying the effects of stress on alcohol-related cognition are not well understood. This study examined changes in event-related potentials (ERPs) elicited by alcohol-related images before and after a stressor compared with a control condition. METHOD: Social drinkers (N = 75; 38 male) were assigned to one of two target subgroups for completion of an oddball task: (a) to detect alcohol targets while ignoring household object distracters and frequently presented nonsense shapes or (b) to detect object targets while ignoring alcohol distracters and nonsense shapes. ERPs were recorded before and after one of two conditions: a stressor or a nonstressful control task. RESULTS: N200 latency and amplitude changes were modulated by stress. Similarly, stress reduced P300 latencies beyond practice effects. For P300 amplitude, the target subgroup interacted with the condition such that the standard "oddball" effect was observed in the control condition but was absent in the stress condition, suggesting that stress may have interfered with the participants' cognitive efficiency, or the ability to ignore task-irrelevant stimuli. CONCLUSIONS: These findings suggest that stress influences the early stages of alcohol-related processing, an effect that may be particularly apparent in ERP latencies. These findings have implications for understanding the neural mechanisms involved with stress and alcohol cue reactivity.

Body mass index moderates gaze orienting biases and pupil diameter to high and low calorie food images.

The primary goal of this study was to examine eye gaze behavior to different kinds of food images in individuals differing in BMI status. Eye-tracking methods were used to examine gaze and pupil responses while normal weight and overweight women freely viewed pairs of different food images: high calorie sweet foods, high calorie savory foods, and low calorie foods. Self-report measures of hunger, state and trait cravings, and restrained eating were also obtained. Results revealed orienting biases to low calorie foods and decreases in pupil diameter to high calorie sweet foods relative to low calorie foods in the overweight group. Groups did not differ in the average amount of time spent gazing at the different image types. Furthermore, increased state cravings were associated with larger pupil diameters to high calorie savory foods, especially in individuals with lower BMIs. In contrast, restrained eating scores were associated with a decreased orienting bias to high calorie sweet foods in the high BMI group. In conclusion, BMI status appears to influence gaze parameters that are less susceptible to cognitive control. Results suggest that overweight individuals, especially those who diet, have negative implicit attitudes toward high calorie foods, especially sweets.

Ocular imaging of attentional bias among college students: automatic and controlled processing of alcohol-related scenes.

OBJECTIVE: Heavy episodic drinking in college is an issue of major concern in our society. In the college setting, where alcohol misuse is prevalent, alcohol-related perceptions and automatic attentional biases may be important determinants in students' decisions to engage in risking drinking behaviors. The current study examined college students' attention to alcohol-related beverages in real time using ocular-imaging techniques. The authors hypothesized that alcohol-consumption characteristics such as quantity-frequency of alcohol consumption would predict ocular-imaging indices of attentional bias to alcohol-related images. METHOD: Twenty-six college students successfully completed questionnaires assessing basic demographics and alcohol-consumption characteristics, followed by an eye-tracking task in which they viewed pictorial stimuli consisting of photographs of alcohol-related scenes, household objects, or a combination of these items. RESULTS: Quantity-frequency index (QFI) of alcohol consumption was positively related to the percentage of initial ocular fixations on the alcohol-related items (r = .62, p = .001), whereas QFI negatively predicted the percentage of initial ocular fixations on the control images (r = -.60, p = .002). In addition, QFI positively predicted participants' dwell time on alcohol-related images (r = .57, p = .005), and negatively predicted dwell time on control images (r = -.41, p = .05). Age at first drink and days since last alcohol consumption were not related to eye-tracking metrics. CONCLUSIONS: Ocular-imaging methods are a valuable tool for use in the study of attentional bias to alcohol-related images in college drinkers. Further research is needed to determine the potential application of these methods to the prevention and treatment of alcohol misuse on college campuses.

Sex-specific associations of body mass index with mood disturbance during smoking abstinence.

OBJECTIVE: Previous reports have suggested an inverse relationship between body mass index (BMI) and negative mood in women. However, little is known about the potential association of these variables under stressful conditions, such as those experienced during smoking cessation. The current investigation examined the relationship of BMI and various indices of mood in a sample of male and female cigarette smokers undergoing cessation. METHODS: Along with baseline assessments of variables such as depression and anxiety, total mood disturbance and perceived stress were assessed via self-report during both baseline (e.g. the smoking period) and the early phases of smoking cessation. RESULTS: Among female participants, higher BMI was associated with lower levels of mood disturbance, perceived stress and depression. Similar analyses in male participants were non-significant. CONCLUSIONS: The results of the current study confirm previous reports regarding the relationship of BMI and mood in women and extend these findings to the early stages of smoking cessation.

Recent EEG and ERP findings in substance abusers.

Research on electroencephalographic (EEG) correlates of substance use has a long history. The present paper provides a review of recent studies--2001 to the present--with a focus on EEG findings in human participants characterized by a history of chronic substance use, abuse or dependence. In some areas (e.g., alcohol and cocaine dependence), the field has attempted to build upon earlier work by incorporating different methodologies or pursuing research questions of a transdisciplinary nature. New areas of inquiry, such as the investigation of EEG differences among users of ecstasy (MDMA) and methamphetamine, have emerged, primarily as a result of an alarming rise in popularity of these drugs.

Effects of acute alcohol consumption in older and younger adults: perceived impairment versus psychomotor performance.

OBJECTIVE: Perceived impairment and psychomotor performance following acute alcohol administration in older (ages 50-74, n=42; 22 male) and younger (ages 25-35, n=26; 12 male) adults were investigated in this study. METHOD: Double-blind, placebo-controlled alcohol administration techniques were designed to produce peak levels of breath alcohol concentration consistent with an episode of social drinking (40 mg/100 ml). Behavioral measures (Trail Making Test, Forms A and B), as well as measures of self-reported perceived intoxication and impairment, were administered on the ascending and descending limbs at common time points after beverage ingestion. RESULTS: Results indicated that psychomotor performance differences did not parallel self-reported levels of perceived impairment. Relative to younger adults, older adults exhibited performance deficits on the ascending limb while simultaneously reporting less perceived impairment. Conversely, on the descending limb, older adults who received alcohol reported more perceived impairment than did those who received placebo, although psychomotor performance between these two groups of older drinkers did not differ. For younger participants, a moderate dose of alcohol facilitated performance on the ascending limb; however, these differences were not reflected on the descending limb. CONCLUSIONS: These results reinforce the common knowledge that self-reported measures may not provide an accurate reflection of performance outcomes and, importantly, that older adults may be impaired even under a moderate dose of alcohol, although they may not be aware (i.e., report) of this impairment.

Alcohol and estrogen replacement therapy in postmenopausal women. Direct and mediated effects on cognitive component processes.

The literature remains contentious regarding the separate and combined effects of moderate drinking and estrogen replacement therapy (ERT) on cognition. In the current study, the authors sought to disentangle the predictive utility of alcohol use, ERT and their interaction on the episodic and semantic memory stores of postmenopausal women. It was predicted that relationships between moderate drinking, ERT and cognition would be attenuated by demographic and health-related factors. Postmenopausal women (n = 298) completed a battery of cognitive tests designed to assess speed and accuracy of episodic and knowledge-based cognitive processing. Potentially confounding variables were categorized and tested as mediators in hierarchical regression analyses. Moderate drinking was a weak predictor of episodic availability prior to removal of potential mediators. ERT use was a significant predictor of episodic and knowledge-based availability; no mediators were identified. Alcohol moderated ERT, as a combined alcohol/ERT variable was shown to be related to cognition. Neither moderate drinking nor ERT use was associated with cognitive speed. These findings suggest that positive relationships between alcohol and cognition are likely mediated by other variables, and should not be regarded as a benefit of drinking. Further, results support ERT as a predictor of knowledge-based and episodic availability, independent of mood stabilization or socioeconomic influences. Finally, alcohol and ERT appear to interact to impact both episodic and knowledge-based performance.

Transdermal nicotine administration and the electroencephalographic activity of substance abusers in treatment.

OBJECTIVES: It is widely recognized that individuals with alcohol or illicit substance abuse disorders often smoke cigarettes. However, few studies have examined the direct effects of nicotine among substance abuse subgroups. The current study examined patterns of electroencephalographic (EEG) activity in alcohol-dependent (AD), stimulant-dependent (StimD), alcohol- and stimulant-dependent (ASD) participants, as well as community controls (CC). All participants were regular smokers. METHODS: After overnight nicotine abstinence, subjects were administered either a high (14 or 21 mg) or low (7mg) dose transdermal nicotine patch. EEG data were collected during a 2 minute eyes open and 5 minute eyes closed baseline recording session, which occurred as part of a larger study of brain electrophysiology. RESULTS: The most interesting finding was a differential pattern of nicotine dose effects by group. EEGs of Controls and ASD participants did not distinguish between high and low nicotine doses; whereas, nicotine administration in the AD and StimD groups resulted in opposite findings across a range of spectral bands. CONCLUSIONS: Although further research is warranted, these results may have implications for the study of smoking cessation and attentional functioning among substance abusers in treatment. These data suggest that nicotine-related changes in neurophysiology may be associated with specific brain areas and/or specific drug histories and reinforce the need for caution in generalizing among such groups.

Are smokers' reasons for smoking related to their body mass indices?

The current analyses addressed the relationship between body mass index and reasons for smoking in 69 cigarette smokers (39 male) enrolled in a smoking cessation study between 2000 and 2003 in a Midwestern metropolitan area. Multivariate analyses of variance were applied. Normal weight and overweight smokers exhibited differential patterns of responding on a questionnaire assessing reasons for smoking. Compared to the overweight group, the normal weight group endorsed smoking for relaxation as well as the sensation of having something to do with one's hands. While preliminary, pursuing body mass index (BMI) in relation to smokers' reasons for smoking may help tailor smoking cessation programs to the needs of these smokers. The study's limitations are noted.

Influence of naltrexone administration on dehydroepiandrosterone sulfate levels in male and female participants.

Dehydroepiandrosterone sulfate (DHEAS) is an excitatory neurosteroid with anti-glucocorticoid properties. Endogenous opioid system blockade is known to activate the hypothalamic-pituitary-adrenal axis and other hormonal systems. However, the literature is sparse regarding the extent to which this blockade acutely influences DHEAS activity. Further, the stability of DHEAS concentrations across short term laboratory studies is not well established. The current study examined these issues in human participants. Using a double-blind, counterbalanced design, 50mg of naltrexone and placebo were administered. Repeated salivary samples were then obtained over a 3h period while participants completed a nociceptive testing paradigm. DHEAS and cortisol concentrations were determined. Naltrexone administration was associated with an increase in cortisol concentrations; however, DHEAS was unaffected by naltrexone and did not vary across the course of the study. This finding is an important contribution to the methodological literature, and may be used to verify the stability of DHEAS for future investigations.

Tobacco use, alcohol dependence, and cognitive performance.

Chronic alcohol abuse has long been associated with a mild, generalized pattern of cognitive decrements. However, it is important to note that problem drinking rarely occurs in isolation from abuse of other drugs. For people dependent upon alcohol, tobacco is one of the mostly commonly coabused substances. Recent research suggests that individuals with alcohol dependency may gravitate toward tobacco use, in part, because of the positive effects of nicotine on aspects of cognitive performance that may be compromised as a consequence of chronic alcohol misuse. In this article, the author focuses on the effects of nicotine on behavioral and electrophysiological indexes of cognitive performance, and the impact of these effects on alcohol-related cognitive decrements. The author discusses implications of these findings in the context of treatment and recovery of people with alcoholism.
