RESUMO

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.

RESUMO

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.

RESUMO

Introduction: This study examined the relationship between stress and pre-gaming (i.e., drinking prior to going out to an event) in female college students. Methods: Thirty-four female college students were grouped as pre-gamers or non-pre-gamers based on self-reported drinking patterns. They completed surveys about alcohol use and mental health and provided a set of salivary cortisol samples upon waking, 30 min later, and at 10am on the same day. Results: Pre-gamers and non-pre-gamers did not differ on demographics or psychosocial variables. Pre-gamers reported riskier drinking overall and had greater endorsement of social, coping, and enhancement drinking motives. Pre-gamers also had lower cortisol levels 30 min after waking and exhibited attenuated CAR. Conclusions: Female collegiate pre-gamers may differ from their peers not only in terms of alcohol consumption and drinking motives, but also on attenuated CAR, a physiological biomarker associated with stress dysregulation and vulnerability to addictive behaviors.

RESUMO

OBJECTIVE: This study explores how adverse childhood experiences (ACEs) relate to race/ethnicity and academic achievement among a sample of college students. PARTICIPANTS: Participants were students attending a large public university in the Southwest (n = 404). Methods: Online surveys captured ACE scores, demographics, and self-reported GPA. RESULTS: Students of Color had higher ACE scores and lower GPAs than White students. Regression analyses also revealed that an ACE score of 4 or higher is associated with lower GPAs, but only for Students of Color (Black and Hispanic students), not for White students. CONCLUSIONS: There are race/ethnic differences in the incidence and impact of adverse childhood experiences on post-secondary academic achievement. Thus, it is important for colleges and universities to create a trauma-informed campus culture and holistic mental health support system, particularly for Students of Color, who may not have had access to high quality care before attending college.

RESUMO

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.

RESUMO

Objective: We investigated psychological factors that might predispose individuals to sad-fish or exaggerate their emotional state online to generate sympathy. Participants: Participants (N = 347) were collegiate social media users from a large university in the Southcentral United States. Methods: Participants completed an anonymous online survey and were categorized as sad-fishers or non-sad-fishers. Groups were compared on attachment style and levels of interpersonal and online social support. Results: Sad-fishers trended toward anxious attachment. Groups did not differ on perceived interpersonal or online social support. Anxious attachment was significantly negatively associated with interpersonal support. Conclusions: Sad-fishing may not be triggered by an acute perceived lack of social support, but rather, may be more strongly related to the persistent trait of anxious attachment. This is a starting-point for understanding the relatively new phenomenon of sad-fishing and may aid in discerning how best to clinically intervene with those who sad-fish.

RESUMO

Overnight sleep can reduce perceived stress, and improve associated cognitive disruptions and negative affect after an acute stressor. Whether a brief nap can also bestow these benefits in a non-sleep-restricted population is currently unknown. In this study that used a between-subjects design, stress was triggered by administering a modified Trier Social Stress Test to two groups of participants (nap [n = 29], wake [n = 41]). All participants were instructed they would give a speech during the study but the topic would be withheld until later, and then completed a math task. After a 40-min break in which participants watched a neutral video or took a nap monitored with electroencephalography, stress was reinforced by presenting the speech topics and giving participants a 10-min preparation period. Next, instead of giving a speech, the study ended and participants were debriefed. Negative affect, perceived stress and working memory were measured at multiple time points before and after the break. Both groups showed lower perceived stress and improved working memory after the break than before, but a nap did not confer additional benefits for perceived stress or working memory beyond taking a break. However, the nap group exhibited lower negative affect after the break than the wake group, and only the nap group showed a reduction in negative affect compared with initial negative affect levels. These results indicate a nap can improve negative emotions accompanying a stressor to a greater extent than taking a break, and suggest that brief naps may be a useful way to improve mood while experiencing an acute stressor.

RESUMO

ObjectiveThis study investigates the association between adverse childhood experiences (ACEs) and mental health among a sample of college students. It also explores whether health behaviors and social support may help to explain the link between ACEs and mental health. Participants: Participants were students at a large public university in the Southwest (n = 404). Methods: A survey captured ACEs, diet, exercise, smoking, binge drinking, perceived social support, depression, anxiety, and demographics. Results: Respondents with four or more ACEs had significantly higher rates of depression and anxiety than respondents with lower ACE scores. We found significant differences in social support, but not health behaviors for the two groups. Finally, social support emerged as a strong predictor of depression/anxiety and a mediator between childhood adversity and mental health outcomes. Conclusions: Our findings confirm the importance of adverse childhood experiences for college student health and indicate a need for interventions for socially isolated students.

RESUMO

It is well established that adverse childhood experiences (ACEs) contribute to the development of mental disorders in adulthood. However, less is known about how childhood trauma impacts the mind and the body, whether the resulting mental disorders have different characteristics than those occurring without these antecedent conditions, and if treatment modalities need to reflect the unique nature of mental disorders rooted in trauma. Survey and biomarker data were gathered from a sample of college students (n = 93) to explore the relationship between childhood trauma and mental health. We examine how neuroimmune systems (inflammation and neuroplasticity) relate to depression and anxiety and whether these associations vary for those with and without a history of childhood trauma. Findings reveal that students with 4 or more ACEs are more likely to have depression and anxiety than students without these experiences. In addition, we find that inflammation (CRP) and neuronal health (BDNF) are associated with mental health disorders among students with four or more ACEs, but not for students without this history. These findings suggest that mental disorders associated with four or more ACEs may be uniquely tied to physiological processes, and consequently, warrant tailored treatments. The implications for mental health intervention include, 1) screening for childhood trauma, inflammation, and neuronal health and 2) referral to treatments which are theoretically and empirically tied to the root causes of mental disorders rather than those designed merely to suppress their symptoms.

RESUMO

Despite the growing interest in adverse childhood experiences and biomarkers, less attention has been paid to multiple biomarkers as representing interrelated systems among college students. Guided by the neuroinflammatory pathway hypothesis, the current project takes the initial step in examining the link between three types of childhood adversity and biomarkers of neuroplasticity (brain-derived neurotropic factor [BDNF]) and low-grade inflammation (C-reactive protein [CRP]) in an overarching model and whether this link may differ in men and women. Undergraduate students (n = 85) were recruited through multiple departments from a state university. The participants responded to the detailed online survey questionnaire on childhood adversity and provided one blood sample via venous blood draw. Given that CRP and BDNF represent two interrelated systems, structural equation models were considered the most suitable for the analyses. The findings partially support neural and inflammatory pathways, such that childhood adversity and particularly family dysfunction have a significant positive effect on BDNF (b = 30.41, p < .01). The link between family dysfunction and CRP was stronger in female students (b = 0.57, p < .05). Results suggest that interventions for college students with family dysfunctions may need to target different physiological and behavioral outcomes for male and female students.

RESUMO

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.

RESUMO

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.

RESUMO

Previous studies have shown alcohol-related attentional biases in social drinkers; however, the temporal dynamics of these biases are not well understood. The current study examined this issue in 94 participants (27 male) categorized as binge drinkers (BD) or non-binge drinkers (NBD). Two versions of an alcohol-related attentional blink (AB) paradigm were used: one with words and one with images. It was predicted that BDs (versus NBDs) would exhibit reduced AB for alcohol cues, which would be enhanced for the pictorial version of the task (versus words). The relationships between AB and alcohol craving, quantity and frequency of alcohol consumption, symptoms of alcohol use disorder, and family history of alcohol use disorder (AUD) were also examined. While an AB was observed for both alcohol and non-alcohol targets in the NBD group, no AB was found for alcohol targets in the BD group. Furthermore, the magnitude of the AB was related to drinking, such that higher self-reported hazardous drinking was associated with smaller ABs to alcohol-related targets. However, AB was not related to craving or family history of AUD. These results suggest that alcohol-related stimuli are processed more efficiently by BDs, especially those with hazardous alcohol consumption patterns. These results may inform treatment and prevention efforts targeting binge drinkers.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

The assessment, treatment and management of aggressive youth represent a major clinical challenge facing pediatric mental health professionals today. Although a number of studies have examined physiological differences among aggressive patients vs. controls, the current literature lacks a comprehensive examination of the electroencephalographic activity of impulsively aggressive juveniles. The current study was designed to fill this void in the literature via a retrospective chart review of 80 male and female juveniles undergoing inpatient treatment for pathologically impulsive aggression. Clinical reports for mid- and late-latency event-related potentials (ERPs) were examined to determine their correlations with aggression characteristics, as well as any differential predictive utility of hemispheric differences and auditory vs. visual potentials. Results indicated that decrements of mid-latency potentials and ERPs evoked by auditory stimuli (vs. late-latency components and visual ERPs) were more highly predictive of aggressive behavior. No significant hemispheric differences were noted. Taken together, these results have theoretical significance for the etiology of impulsive aggression, and perhaps also clinical relevance for the treatment of this condition.
