The Mediating Role of Impulsivity Between Psychological Distress and Alcohol Misuse Among College Students at a Historically Black University

Objective: Alcohol misuse is prevalent and clinically significant among college students. Psychological distress is one factor that has been found to predict alcohol misuse in this population. However, relatively few investigations examined the association of psychological distress to alcohol misuse or its underlying mechanisms among students attending historically Black colleges and universities (HBCUs). The present study examined whether impulsivity explains the relation between psychological distress and alcohol misuse in this population using structural equation modeling. Methods: Participants were 287 undergraduate students attending an HBCU in the southern United States (M_age = 22.5, 66.3% female, 93.7% Black). Results: Impulsivity was found to significantly mediate the association of psychological distress to alcohol misuse, such that higher levels of psychological distress were associated with greater impulsivity which, in turn, was related to more alcohol misuse. Further analyses indicated that attentional impulsivity significantly mediated the association of psychological distress to alcohol misuse. Conclusions: These findings suggest the utility of targeting impulsivity in interventions aimed at preventing and reducing alcohol misuse among college students attending HBCUs who experience psychological distress.     

Difficulties regulating positive emotions and alcohol and drug misuse: A path analysis

IntroductionAlcohol and drugs are widely used among college students. Emotion dysregulation has been identified as a key mechanism in the etiology, maintenance, and treatment of alcohol and drug misuse. Yet, research in this area has been limited by its narrow focus on dysregulation stemming from negative emotions. The goal of the current study was to extend past research by examining the relation of difficulties regulating positive emotions to alcohol and drug misuse.MethodsParticipants were 311 college students (M_age = 19.24; 66.1% female; 66.0% White) who completed measures assessing difficulties regulating positive emotions and alcohol and drug misuse.ResultsStructural equational modeling was used to model the relation between difficulties regulating positive emotions and alcohol and drug misuse. In a hypothesized structural model, higher levels of difficulties regulating positive emotions were found to relate to greater alcohol and drug misuse. Moreover, an alternative model provided support for an association of greater drug (but not alcohol) misuse to higher levels of difficulties regulating positive emotions.ConclusionsIf replicated, findings may suggest the utility of targeting difficulties regulating positive emotions in treatments aimed at reducing alcohol and drug misuse among college students.     

The role of gender in the associations among posttraumatic stress disorder symptom,severity, difficulties regulating emotions,and alcohol misuse

IntroductionThe co-occurrence of posttraumatic stress disorder (PTSD) and alcohol misuse is highly prevalent and clinically significant. Delineating mediators (i.e., emotion regulation) and moderators (i.e., gender) of this co-occurrence is critical to understanding underlying mechanisms of such comorbidity and intervention development/refinement.MethodThe present study examined the potential mediating role of difficulties regulating negative and positive emotions in this association as well as the moderating role of gender using a moderated mediation analysis. Participants were 475 trauma-exposed community adults recruited from Amazon's Mechanical Turk (MTurk) platform (M_age = 35.62, 55.4% women, 77.0% White).ResultsDifficulties regulating positive (but not negative) emotions significantly mediated the relation between PTSD symptom severity and alcohol misuse. Further, gender was found to significantly moderate each of the paths in this mediation model.ConclusionsResults highlight gender-specific intervention targets for reducing alcohol misuse among trauma-exposed individuals who experience PTSD symptoms.     

Drinking motives among heavy-drinking veterans with and without posttraumatic stress disorder

Objective: This study examined patterns of drinking motives endorsed by heavy drinking veterans who either did or did not meet criteria for posttraumatic stress disorder (PTSD). Method: Data were collected from 69 veterans of Operations Enduring Freedom or Iraqi Freedom (OEF/OIF) who had screened positive for hazardous drinking. The sample was 91.3% male and 65.2% Caucasian. Based on a structured interview, 58% of the sample met criteria for PTSD. Results: The PTSD group scored higher than the non-PTSD group on scales measuring drinking to cope with anxiety and depression and similarly to the non-PTSD group on scales measuring social, enhancement and conformity motives. Coping and social motives were significantly correlated with adverse alcohol consequences. Overall, the PTSD group showed stronger relations between coping scales and aspects of alcohol misuse, relative to the non-PTSD group. Conclusion: These findings suggest first, that among heavy drinking OEF/OIF veterans there is a high base rate of PTSD. Second, coping motives are frequently reported in this population, and they seem to be related to a more severe pattern of alcohol-related consequences. These findings underscore the importance of assessing the interplay between PTSD and substance abuse in trauma-exposed samples.     

Exploring patterns of alcohol misuse in treatment-seeking UK veterans: A cross-sectional study

AimsTo explore patterns of alcohol misuse in a sample of treatment-seeking veterans compared to the UK Armed Forces personnel population and the general public. Furthermore, the present study investigated which variables were associated with alcohol misuse in this sample, and in particular what factors were associated with increased or decreased severity of alcohol misuse.MethodThe present study investigated alcohol misuse in treatment-seeking veterans and compared it with the UK Armed Forces and the general public. In addition, it explored associations between sociodemographic, physical health and mental health variables and alcohol misuse.ResultsResults suggested that treatment-seeking veterans report different patterns of alcohol misuse compared to the UK Armed Forces and the general public. This group was more likely to report alcohol dependence and alcohol-related harm. They also reported higher levels of overall alcohol misuse than the general public. Mental health problems including PTSD, anxiety and depression, as well as anger, functional impairment and being single were all related to greater alcohol misuse. Being older and not in work were related to reduced alcohol misuse.ConclusionsThese findings add further weight to the importance of ensuring appropriate support is provided to personnel leaving the Armed Forces. Treatment-seeking veterans have specific patterns of alcohol-related needs that should be addressed. Knowing more about the common alcohol-related problems in this group can help inform and improve mental health interventions. Findings on related variables will help in identifying those individuals who may be at most risk of alcohol-related problems.     

Social anxiety and drinking game behaviors among Australian university students

IntroductionThe relationship of social anxiety with alcohol use/problems has been examined among college student samples, but the relevance of findings to drinking game (DG) consumption/gaming consequences is not well understood due to a paucity of research.MethodsA cross-sectional sample of 224 Australian university students aged 18–25 years (M_age = 20.7 years; 63% female) was utilized for analysis. Participants completed an online questionnaire which included measures of social anxiety, DG consumption, DG consequences, and motives for playing drinking games.ResultsSocial anxiety was positively associated with DG consequences, but not DG consumption. However, after controlling for DG motives, social anxiety was no longer associated with DG consequences. Rather, an indirect effect of social anxiety on DG consequences via conformity DG motives was identified.ConclusionsOur findings highlight the vulnerability of socially anxious students to experiencing greater drinking game consequences, but the importance of considering motives specific to playing DGs when examining these relationships.     

Understanding sexual assault risk perception in college: Associations among sexual assault history,drinking to cope,and alcohol use

IntroductionSexual assault history and alcohol use are associated with higher likelihood of subsequent sexual assault. Alcohol use and drinking to cope are associated with re-assault, but it is unclear whether these factors are associated with malleable constructs like sexual assault risk perception. This study examined typical weekly drinking and drinking to cope motive as factors underlying the association between sexual assault history and risk perception.MethodsBoth perceived likelihood of experiencing incapacitated sexual assault and when to leaving a hypothetical sexual assault scenario were assessed as indicators of sexual assault risk perception. 660 female college students recruited from psychology courses completed questionnaires online.ResultsResults revealed that sexual assault history severity was positively associated with perceived incapacitated sexual assault likelihood and when to leave a risky scenario. Drinking to cope with anxiety was positively associated with perceived incapacitated sexual assault likelihood. Among women who reported regular drinking, typical weekly drinking was positively associated with when to leave a risky scenario, such that women who reported more weekly drinks stayed in a potentially risky scenario longer than women who reported fewer weekly drinks.ConclusionsThese findings suggest that alcohol use and drinking to cope with anxiety are associated with risk perception. Sexual assault history was associated with both perceived incapacitated sexual assault likelihood and when to leave a hypothetical scenario. Alcohol use and drinking to cope are two potential points of intervention for sexual assault risk reduction programs, but further examination is needed.     

Maternal and Paternal Alcohol Misuse and Alcohol-Related Outcomes Among College Students

Using a large college student sample (N = 1,095), the present study examined whether the relationship between parental alcohol abuse and offspring alcohol use varied as a function of parent and offspring gender, and whether the relationship to the non-substance-abusing mother or father buffered against the risk associated with being an adult child of an alcoholic (ACOA). Among women, maternal ACOAs (i.e., the mother only was suspected of alcohol misuse) had the greatest risk of problematic alcohol consumption, whereas among men, both parent ACOAs (i.e., both parents were suspected of alcohol misuse) had the greatest risk of problematic alcohol consumption. No support was found for the buffering hypothesis. We discuss implications of our findings and future directions.     

Trauma exposure and heavy drinking and drug use among college students: Identifying the roles of negative and positive affect lability in a daily diary study

Trauma exposure is linked to heavy drinking and drug use among college students. Extant research reveals positive associations between negative affect lability and both trauma exposure and alcohol use. This study aimed to extend past research by using daily diary methods to test whether (a) individuals with (versus without) trauma exposure experience greater negative and positive affect lability, (b) negative and positive affect lability are associated with heavy drinking and drug use, and (c) negative and positive affect lability mediate the relations between trauma exposure and heavy drinking and drug use. Participants were 1640 college students (M age = 19.2, 54% female, 80% European American) who provided daily diary data for 30 days via online surveys. Daily diaries assessed negative and positive affect and substance use (i.e., percent days of heavy drinking, percent days of drug use, total number of drugs used). Individuals with (versus without) a history of trauma exposure demonstrated higher levels of negative and positive affect lability. Negative, but not positive, affect lability was associated with percent days of heavy drinking, percent days of drug use, and total number of drugs used, and mediated the associations between trauma exposure and heavy drinking and drug use outcomes. Findings provide support for the underlying role of negative affect lability in the relations between trauma exposure and heavy drinking and drug use among college students, suggesting that treatments targeting negative affect lability may potentially serve to reduce heavy drinking and drug use among trauma-exposed college students.     

The role of mindfulness skills in terms of anxiety-related cognitive risk factors among college students with problematic alcohol use

Background: The aim of the current study was to examine the associations between the specific mindfulness skills of observing, describing, awareness, nonjudgment, and nonreactivity in terms of anxiety sensitivity (AS), distress tolerance (DT), and intolerance of uncertainty (IU) among college students with problematic alcohol use. Methods: Participants were 202 (69.3% male; M_age = 18.96, SD = 2.24, range = 18–45 years) undergraduate college students with problematic alcohol use who completed self-report measures for course credit. Results: Results indicated that after controlling for the effects of gender, smoking status, marijuana use status, and negative affectivity, greater use of the mindfulness skill of observing was associated with higher AS, greater describing was associated with lower AS and higher DT, greater nonjudgment was associated with lower AS and IU and higher DT, and greater nonreactivity was associated with increased DT. Awareness did not significantly predict any of the examined risk factors. Conclusions: These results suggest that specific mindfulness skills are associated with a greater tolerance of physiological, emotional, and uncertain states. An important next step will be to examine whether mindfulness skills are associated with decreased problematic alcohol use due to improvements in these anxiety-related risk factors.     

Contribution of Alcohol and Nicotine Dependence to the Prevalence of Depressed Mood in Different Ethnic Groups in The Netherlands: The HELIUS Study

Abstract

Objective: Ethnic minorities report different levels of drinking and smoking and higher rates of depression compared to native populations. In this study we aimed to investigate in six ethnic groups whether tobacco and alcohol use were associated with depressive symptoms, which are more prevalent in ethnic minorities.

Methods: Cross-sectional data from the multi-ethnic Healthy Life in an Urban Setting (HELIUS) study sample (N?=?22,471) was used, comprising 4,580 native Dutch participants which were compared with participants from five ethnic minority groups (3,259 South Asian Surinamese, 4,292 African Surinamese, 2,262 Ghanaian, 3,891 Turkish, and 4,187 Moroccan).

Results: Alcohol misuse was positively associated with depressed mood in all ethnic groups except for the Dutch and the Ghanaians. Nicotine dependence was positively associated with depressed mood in all ethnic groups except for the Ghanaian group.

Conclusions: Alcohol misuse and nicotine dependence were significantly associated with depressed mood in most but not all ethnic groups and especially in men. However, across all groups the contribution of alcohol misuse and nicotine dependence to depressed mood was small. Prospective multi-ethnic studies should confirm whether the relations are causal and elucidate their direction.     

Alcohol-Impaired Driving: The Influence of Adverse Rearing Environments,Alcohol, Cannabis Use,and the Moderating Role of Anxiety

Background: The rate of alcohol-impaired driving (AID) increases during the college years and students who have reported adverse rearing environments appear to be at increased risk for the development of alcohol and drug use behaviors. Alcohol and cannabis are the most commonly used drugs by college students, and these substances are particularly predictive of substance-impaired driving. Objectives: The present study aimed to investigate whether adverse rearing environment experiences and level of alcohol and cannabis use are related to the frequency of alcohol-impaired driving and whether anxiety might buffer or accelerate this effect. Methods: Data regarding adversity, drug use, anxiety, and AID were obtained from 1,265 students annually, from first to final year of college, over four waves (Mean Age at wave 1 = 18.5 years). Results: Structural equation modeling supported associations among childhood adversity, alcohol, cannabis, and anxiety symptoms. A significant mediation effect was found such that adversity was predictive of AID via alcohol use and cannabis use. Among men, anxiety symptoms accelerated the path from increased cannabis use and decelerated the path from increased alcohol use to AID frequency. Conclusions/Importance: Childhood adversity is a developmental risk precursor to drug use and AID, whereas anxiety might serve a risk or protective factor to AID, contingent on the drug used.     

Factors Associated With Marijuana use and Problems Among College Students in Colorado

Background: Past studies have shown that heavy marijuana use can impact student outcomes. Frequent use and misuse of marijuana have been associated with a range of psychological and personality factors in young adults, but there has been limited research focused on the college environment in states where marijuana has been legalized for recreational purposes.

Objectives: We examined whether marijuana use and problems were associated with a range of demographic, personality, and psychological variables among college students at a midsized Colorado university. Methods: This cross-sectional study included 300 university students who submitted a urine screen and completed measures on marijuana use, problem marijuana use, anxiety, depression, impulsivity, and openness to experience. Results: Last year and recent marijuana use were high (65%, 29%; respectively), as assessed through self-report and a urine screen. Using logistic regression, male sex and greater openness to experience were associated with greater marijuana use when assessed with a urine screen, while greater openness to experience and impulsivity were associated with greater self-reported marijuana use within the last year. In the final step of a hierarchical linear regression model, male sex and greater impulsivity and depression–but not openness to experience, general anxiety or social anxiety–were associated with greater problem marijuana use. Conclusions: This study extends the literature on psychological and personality correlates of marijuana use among college students. It may be useful to assess these correlates to identify students who are at risk of developing problems and in intervening with students with problem use.     

Low rates of alcohol and tobacco use,strong cultural ties for Native American college students in the Southwest

IntroductionCollege attendance is associated with an increased risk for substance use yet we know little about substance use among Native American college students and its regional variation. This study examined alcohol, tobacco, and drug use and their relation to gender, institution, age, and cultural involvement among Native American college students in the Southwest.MethodsNative American community college and university students in a large Southwest city (N = 347) completed an online survey about past-month and lifetime substance use and involvement in cultural activities.ResultsCultural involvement was related to less past-month substance use. In the past month, 43% drank alcohol, 27% binge drank, 20% used drugs, and 13% were current smokers. Males, community college students, and older individuals were more likely to have a positive CAGE-AID and have used drugs more than 100 times. Younger individuals were more likely to use marijuana in the past month.ConclusionsThese findings highlight cultural strengths and comparatively low rates of tobacco and alcohol use among Native American college students in the Southwest.
