Fast food and anxiety symptoms of Chinese multi-ethnic adolescents: The moderating role of regulatory emotional self-efficacy

BACKGROUND

Although previous studies demonstrated an association between fast food intake and anxiety symptoms in adolescents, this relationship has not been studied in Chinese multi-ethnic adolescents. The purpose of this study is to investigate the aforementioned association and the potential moderating effect of regulatory emotional self-efficacy (RESE) among Chinese multi-ethnic adolescents.

METHODS

A cluster random sampling of 8500 middle school students from 11 counties in Yunnan province was conducted. The Depression Anxiety Stress Scale-21 was utilized to assess anxiety symptoms, while the food frequency questionnaire was employed to gather data on eating behaviors. The association between fast food intake, RESE, and anxiety symptoms was analyzed using generalized linear models. The moderating effect of RESE on the association between fast food intake and anxiety symptoms was examined using structural equation models.

RESULTS

The positive rate of anxiety symptoms in middle school students was 48.5 % (4120/8500). The positive rate of depressive symptoms in females (53.3 %, 2301/4316) was higher than that in males (43.5 %, 1819/4184). Chinese fast food intake (males vs females: β = 0.26, 95%CI:0.14-0.39; β = 0.16, 95%CI:0.02-0.29), expressing positive affect (β = -0.04, 95%CI:-0.07-0.01; β = -0.06, 95%CI:-0.10-0.03) and managing anger/irritation affect (β = -0.11, 95%CI:-0.14-0.08; β = -0.16, 95%CI:-0.19-0.12) was associated with anxiety symptoms in males and females (all P < 0.05). Takeaway fast food intake (β = 0.19, 95%CI:0.02-0.35) and managing despondency/distress affect (β = -0.08, 95%CI:-0.12-0.04, P < 0.001) was associated with anxiety symptoms in females (all P < 0.05). RESE significantly inversely moderated the association between fast food intake and anxiety symptoms (all participants: β = -0.11; males: β = - 0.08; females: β = - 0.14; all P < 0.01).

LIMITATIONS

Association observed in the cross-sectional study is uncertain and need to be confirmed in cohort studies.

CONCLUSION

Our findings suggest that fast food intake may be associated with an increased risk of anxiety symptoms among Chinese multi-ethnic adolescents, while good RESE can potentially mitigate this risk.

Sexism and alcohol-related problems among women: The role of social anxiety and coping motivated drinking

BACKGROUND AND OBJECTIVES

Experiencing sexism is related to more alcohol-related problems, presumably via drinking to cope with negative affect associated with experiencing sexism. Yet no known studies have directly tested whether the relation of sexism to alcohol problems occurs via relevant negative emotions and drinking to cope with negative emotions. Given that sexism is a type of negative evaluation, social anxiety may be one type of negative affect that plays a role in sexism's relation with drinking behaviors.

METHOD

This study tested whether sexism was related to alcohol-related problems via the serial effects of social anxiety and coping-motivated alcohol use among 836 cis-female undergraduates who endorsed past-month alcohol use.

RESULTS

Past-year experiences with sexism were positively correlated with coping and conformity-motivated alcohol use, alcohol problems (but not peak estimated blood alcohol content, eBAC), social anxiety, and depression. After statistically controlling for depression and peak eBAC, sexism was indirectly related to alcohol problems via the serial effects of social anxiety and drinking motives (coping, conformity).

DISCUSSION AND CONCLUSIONS

Results highlight the important role of social anxiety and drinking to cope with negative emotions and to fit in with peers who drink in relation of sexism with alcohol-related problems.

SCIENTIFIC SIGNIFICANCE

This is the first known study to find that experiences of sexism are related to alcohol problems via the serial effects of social anxiety and coping and conformity-motivated drinking. This is also the first known study to find that sexism is related to more conformity-motivated drinking.

Late-stage borreliosis and substance abuse

Background

Infectious diseases can contribute to substance abuse. Here, a fatal case of borreliosis and substance abuse is reported. This patient had a history of multiple tick bites and increasing multisystem symptoms, yet diagnosis and treatment were delayed. He experimented with multiple substances including phencyclidine (PCP), an N-methyl-d-aspartate (NMDA) receptor antagonist that opposes NMDA agonism caused by Borrelia infection. During PCP withdrawal, he committed one homicide, two assaults, and suicide.

Methods

Brain tissue was obtained from autopsy and stained for microglial activation and quinolinic acid (QA). Immunoflouresence (IFA) and fluorescence in situ hybridization (FISH) were used to identify the presence of pathogens in autopsy tissue.

Results

Autopsy tissue evaluation demonstrated Borrelia in the pancreas by IFA and heart by IFA and FISH. Activated microglia and QA were found in the brain, indicating neuroinflammation. It is postulated that PCP withdrawal may exacerbate symptoms produced by Borrelia-induced biochemical imbalances in the brain. This combination may have greatly increased his acute homicidal and suicidal risk. Patient databases also demonstrated the risk of homicide or suicide in patients diagnosed with borreliosis and confirmed multiple symptoms in these patients, including chronic pain, anxiety, and anhedonia.

Conclusions

Late-stage borreliosis is associated with multiple symptoms that may contribute to an increased risk of substance abuse and addictive disorders. More effective diagnosis and treatment of borreliosis, and attention to substance abuse potential may help reduce associated morbidity and mortality in patients with borreliosis, particularly in endemic areas.

A latent profile analysis of social anxiety, depression, and pregaming motives among heavy-drinking college students

BACKGROUND

Pregaming is a high-risk drinking behavior that is associated with heavy drinking and negative alcohol-related consequences. College students may engage in pregaming for several reasons, including to enhance social experiences or cope with negative affect. Research shows that associations between drinking, social anxiety, and depression are multifaceted. However, our understanding of the complex associations of mental health symptoms with pregaming motives and behaviors remains limited.

METHODS

This study examined heterogeneity in how pregaming motives, social anxiety, and depression associate with past 30-day pregaming variables (quantity, frequency, and negative consequences). We used latent profile analysis (LPA) in a sample of heavy-drinking university students (N = 479).

RESULTS

LPA results indicated four profiles: mild/moderate social anxiety and depression symptoms, moderate motives (n = 285), minimal social anxiety and depression symptoms, low motives (n = 61), subclinical/elevated social anxiety and depression symptoms, high motives (n = 75), and clinically elevated social anxiety and depression symptoms, moderate motives (n = 58). The subclinical/elevated symptoms, high motives profile reported the highest pregaming frequency and consequences, including blackouts. Individuals in the clinically elevated symptoms, moderate motives profile reported more consequences than those in the minimal symptoms, low motives and mild/moderate symptoms, moderate motives profiles. Individuals in the minimal symptoms, low motives profile reported the fewest consequences.

CONCLUSIONS

Among these students, social anxiety and pregaming motives were associated with more frequent pregaming and social anxiety and depression were associated with greater negative consequences. Interventions that target pregaming-specific motives among students with mental health symptoms may be warranted to reduce this risky behavior and associated drinking-related harm.

Social concerns about anxious arousal explain the association between neural responses to anxious arousal pictures and social anxiety

Cognitive theories propose that social anxiety disorder involves heightened attention to anxious arousal symptoms due to worries that they may evoke rejection from others. Supporting this, studies have shown that social anxiety is related to greater attention to representations of anxious arousal and to anxiety sensitivity social concerns, which refers to sensitivity to feelings of anxious arousal during social situations. However, this has not yet been tested using neural indices of attention to images depicting anxious arousal. To examine these associations, the current study examined early and sustained attentional bias to anxious arousal images using the P2 and the late positive potential (LPP), respectively. Electroencephalogram data were collected while a non-clinical sample of undergraduate students (N = 106) viewed images of people exhibiting anxious arousal in addition to blocks of negative and neutral images from the IAPS. The neural response to anxious arousal images was isolated using residual scores (e.g., using linear regression to predict the P2 elicited by anxious arousal images from the P2 elicited by neutral images (P2neutral→AA) or negative images (P2negative→AA), then saving the unstandardized residuals). There was an indirect effect of the P2neutral→AA and P2negative→AA waveforms that was explained by anxiety sensitivity social concerns. Additionally, there was an indirect effect of both LPP waveforms on social anxiety symptoms during the early time window of the LPP (400-700 ms). At the later time window of the LPP (700-1000 ms), there was an indirect effect of the LPPneutral→AA residual waveform, but not the LPPnegative→AA, on social anxiety symptoms.

Motivations for Cannabis Use in Individuals with Social Anxiety Disorder (SAD)

Social anxiety disorder (SAD) is a debilitating psychiatric condition. Consequently, it is common for those affected to resort to cannabis to cope with their symptoms. The primary objective of this study was to understand the differences between motivations for cannabis use in adults with and without SAD. We employed convergent, mixed methods to collect the data. Twenty-six individuals (age: 27.9 ± 7.3 years; 54% female) with and twenty-six (age: 27.4 ± 6.7 years; 50% female) without SAD were administered Marijuana Motives Measure (MMM). Motivations to initiate, continue, and maintain cannabis use were assessed in 12/26 participants in both groups using in-depth interviews. Cannabis weekly consumption was 3.8-fold and frequency 1.3-fold higher in the SAD group. Coping (F = 10.02; p <0.001; η2 = 0.46) and social (F = 2.81; p = 0.036; η2 = 0.19) motivations were also higher in the SAD group, after controlling for age, sex, and current CUD. The need to cope with symptoms of SAD may have been the driving force for repeated cannabis consumption. Psychoeducational programs educating children about the risk of using cannabis to cope with SAD should be implemented in vocational settings early on.

Psychostimulant Misuse Among American Indian, Alaskan Native, or Native Hawaiian College Students in the U.S. From 2015 to 2019

Introduction

This study examines factors associated with psychostimulant misuse, including polysubstance use and social factors, among the understudied American Indian/Alaska Native/Native Hawaiian (AI/AN/NH) college student population.

Methods

Data were from the 2015 to 2019 American College Health Association-National College Health Assessment IIc (ACHA-NCHA IIc) survey. Multivariable logistic regression models and odds ratios were used to estimate associations between psychostimulant misuse and potential risk and protective factors among AI/AN/NH college students, including licit and illicit substance use, social support, relationship factors, exposure to violence or abuse, mental health symptoms, drug and alcohol education, and sample demographics.

Results

Opioid misuse among AI/AN/NH college students significantly increased the odds of using psychostimulants. Specifically, for cocaine use, the adjusted odds ratio (aOR) was 3.17 with a 95% confidence interval (C.I.) of 2.17 to 4.63; for methamphetamine use, the aOR was 38.87 (95% C.I. 19.24-78.52). For amphetamine misuse among non-Tobacco users, the aOR was 5.47 (95% C.I. 3.49-8.55), while among Tobacco users, the aOR was 2.65 (95% C.I. 2.07-3.41). For cocaine and other stimulant misuse, the aOR was 3.64 (95% C.I. 2.30-5.67). Additionally, the use of other types of licit and illicit substances was associated with greater odds of psychostimulant use and misuse. Conversely, factors such as age, living on campus, and residing in parental/guardian housing were linked with lower odds of psychostimulant use and misuse.

Conclusion

Substance use prevention and treatment interventions targeting AI/AN/NH college students should address polysubstance use, including the combined use of opioids and psychostimulants. Substance use interventions should not be siloed to focus narrowly on single substances but rather should leverage potential protective factors against substance use, such as promoting supportive campus and family living conditions and other social support networks, in broad efforts to reduce multiple forms of substance use among AI/AN/NH students.

Implications of Social Anxiety Symptoms in Adults with Autism Spectrum Disorder: Is There a Predictive Role of Interpersonal Sensitivity and Substance Abuse?

Social anxiety disorder (SAD) has been frequently reported by subjects with Autism Spectrum Disorder (ASD). However, interestingly, the overlap between social anxiety and autistic traits may sometimes impede ASD diagnosis in subjects without intellectual or language impairment. The aim of the present work was to evaluate the presence and correlates of social phobic features among subjects with ASD, with a specific focus on evaluating which social anxiety symptoms may be statistically predictive of an ASD diagnosis. With this purpose, 48 subjects with ASD and 48 gender- and age- matched healthy controls (HCs) were recruited and assessed with the SHY-SV and the AdAS Spectrum questionnaires. Results highlighted higher scores in all SHY-SV Spectrum domains and total scores for the ASD group. Moreover, AdAS Spectrum scores were significantly correlated with all SHY-SV domain and total scores. A logistic regression analysis highlighted the SHY-SV Interpersonal sensitivity and Substance Abuse domains scores as significant positive predictors of an ASD diagnosis. These results confirm the link between ASD and SAD. Because of this association, particular attention should be paid to subjects with high interpersonal sensitivity traits and substance abuse problems.

Towards a New Dynamic Interaction Model of Adolescent CUD Manifestation, Prevention, and Treatment: A Narrative Review

Background

Cannabis is one of the most popular drugs of the 21st century, especially among adolescents and young adults. Evidence of a variety of lasting neuropsychological deficits as a result of chronic cannabis use has increased. Furthermore, regular cannabis use is found to be a predictor of mental health problems, less motivation in school, and school dropout.

Aim

Our goal is to propose a theoretical model of adolescent cannabis use disorder (CUD) based on Zinberg's drug, set, and setting model and explicated by a review of the literature on adolescent cannabis use to improve the prevention and treatment of CUD for adolescents.

Methods

PubMed and Web of Science were searched for relevant publications as part of a hypothesis-based and model-generating review.

Results

Individual (set) and environmental (setting) risk factors play important roles in the development of CUD in adolescents. School performance, motivation, and attendance can be negatively influenced by persistent cannabis use patterns and adolescent brain development can consequently be impaired. Thus, cannabis use can be understood as both being the cause of poor school performance but also the consequence of poor school performance. To prevent and reduce adolescent CUD the drug, set, and setting must all be considered. It is important to notice that the multiple feedback loops (indicated in our dynamic interaction model) are not mutually exclusive, but offer important intervention focus points for social workers, addiction professionals, parents, and other care takers.

Conclusion

We argue that the three dimensions of drug, set, and setting contribute significantly to the eventual manifestation of CUD. Based on our dynamic interaction model, recommendations are made for possible preventive and therapeutic interventions for the treatment of adolescents and young adults with CUD.

Preexisting mental health disorders and risk of opioid use disorder in young people: A case-control study

AIM

Opioid use disorder (OUD) is a leading cause of preventable mortality amongst young people worldwide. Early identification and intervention of modifiable risk factors may reduce future OUD risk. The aim of this study was to explore whether the onset of OUD is associated with preexisting mental health conditions such as anxiety and depressive disorders in young people.

METHODS

A retrospective, population-based case-control study was conducted from 31 March 2018 until 01 January 2002. Provincial administrative health data were collected from Alberta, Canada.

CASES

Individuals 18-25 years on 01 April 2018, with a previous record of OUD.

CONTROLS

Individuals without OUD were matched to cases, on age/sex/index date. Conditional logistic regression analysis was used to control for additional covariates (e.g., alcohol-related disorders, psychotropic medications, opioid analgesics, and social/material deprivation).

RESULTS

We identified N = 1848 cases and N = 7392 matched controls. After adjustment, OUD was associated with the following preexisting mental health conditions: Anxiety disorders, aOR = 2.53 (95% CI = 2.16-2.96); depressive disorders, aOR = 2.20 (95% CI = 1.80-2.70); alcohol-related disorders, aOR = 6.08 (95% CI, 4.86-7.61); anxiety and depressive disorders, aOR = 1.94 (95% CI = 1.56-2.40); anxiety and alcohol-related disorders, aOR = 5.22 (95% CI = 4.03-6.77); depressive and alcohol-related disorders, aOR = 6.47 (95% CI = 4.73-8.84); anxiety, depressive and alcohol-related disorders, aOR = 6.09 (95% CI = 4.41-8.42).

DISCUSSION

Preexisting mental health conditions such as anxiety and depressive disorders are risk factors for future OUD in young people. Preexisting alcohol-related disorders showed the strongest association with future OUD and demonstrated an additive risk when concurrent with anxiety/depression. As not all plausible risk factors could be examined, more research is still needed.

Understanding the Dimensions of Post-Event Processing: Applying a Bifactor Modeling Approach to the EPEPQ-15

Social anxiety disorder is maintained in part by rumination about past social experiences, known as post-event processing. The Extended Post-Event Processing Questionnaire (EPEPQ-15) assesses post-event processing as three correlated factors. Competing against this structure is a bifactor model that has not yet been evaluated for the EPEPQ-15. These models were tested for the conventional state version of the EPEPQ-15 and a new trait version in two separate samples (Ns = 327 and 351). In both samples, the fit of the bifactor model was better than that of correlated factor models. Moreover, the results did not support the group factors, indicating that a unidimensional interpretation of the EPEPQ-15 is most appropriate. The general dimension of the EPEPQ-15 was highly correlated with social interaction anxiety, beliefs related to social anxiety, anticipatory processing, and safety behaviors. These results overall suggest post-event processing is best conceptualized as a unitary construct.

The Nonlinear Relationship Between Body Mass Index (BMI) and Perceived Depression in the Chinese Population

Purpose

Existing studies on the association between BMI and depression report conflicting results with some demonstrating a positive relationship, while others a negative link or insignificant correlation. Very limited research on the nonlinear relationship between BMI and depression has yet to clarify the reliability and robustness of the potential nonlinearity and whether a more complex association exists. This paper aims to systematically investigate the nonlinear relationship between the two factors applying rigorous statistical methods, as well as explore the heterogeneity of their association.

Materials and Methods

A large-scale nationally representative dataset, Chinese General Social Survey, is used to empirically analyze the nonlinear relationship between BMI and perceived depression. Various statistical tests are employed to check the robustness of the nonlinearity.

Results

Results indicate that there is a U-shaped relationship between BMI and perceived depression, with the turning point (25.718) very close to while slightly larger than the upper limit of the range of healthy weight (18.500 ≤ BMI < 25.000) defined by World Health Organization. Both very high and low BMIs are associated with increased risk for depressive disorders. Furthermore, perceived depression is higher at almost all BMI levels among individuals who are older, female, lower educated, unmarried, in rural areas, belonging to ethnic minorities, non-Communist Party of China members, as well as those with lower income and uncovered by social security. In addition, these subgroups have smaller inflection points and their self-rated depression is more sensitive to BMI.

Conclusion

This paper confirms a significant U-shaped trend in the association between BMI and depression. Therefore, it is important to account for the variations in this relationship across different BMI categories when using BMI to predict depression risk. Besides, this study clarifies the management goals for achieving an appropriate BMI from a mental health perspective and identifies vulnerable subgroups at higher risk of depression.

Social anxiety disorder is a risk factor for alcohol use problems in the National Comorbidity Surveys

BACKGROUND

According to the self-medication and biopsychosocial models, individuals with social anxiety disorder (SAD) are at increased risk of developing an alcohol use disorder (AUD) as alcohol represents a maladaptive coping mechanism for some sufferers of SAD. The SAD-to-AUD causation was earlier supported in Norwegian longitudinal twin data and later questioned using longitudinal data from the USA.

METHODS

We re-analyzed partly the same USA-based data (National Comorbidity Surveys, n = 5001), conducting theoretical and simulation analyses on different formulations of temporality and using real-data Logistic regression analysis to investigate whether baseline SAD was associated with AUD at the follow-up.

RESULTS

Upon proper analysis of temporality, SAD preceded AUD. Specifically, SAD was the only one of the seven anxiety disorders that predicted 10-year later AUD after adjusting for all other anxiety disorders and AUD at the baseline (odds ratio was 1.70% and 95% confidence interval 1.12-2.57). SAD was also associated with incident AUD (OR = 1.64, 95% CI = 1.14-2.37). We provide formal, simulation-based, and data-based arguments on how certain flawed models of incidence attenuate the temporal association.

CONCLUSIONS

We demonstrated temporality and specificity in SAD-to-AUD association, which are considered signs of causation. We further identified and discussed problems in previous statistical analyses with different conclusions. Our findings add support for models positing causal effects of SAD on AUD, such as the self-medication and biopsychosocial models. The available evidence suggests that treating SAD should incur better chances of preventing AUD compared to treating other anxiety disorders, which lack comparable evidence on causation.

Opioid and cannabis co-use: The role of opioid use to cope with negative affect

INTRODUCTION

The opioid epidemic is a significant public health concern, particularly among adults with chronic pain. There are high rates of cannabis co-use among these individuals and co-use is related to worse opioid-related outcomes. Yet, little work has examined mechanisms underlying this relationship. In line with affective processing models of substance use, it is possible that those who use multiple substances do so in a maladaptive attempt to cope with psychological distress.

METHOD

We tested whether, among adults with chronic lower back pain (CLBP), the relation between co-use and more severe opioid-related problems would occur via the serial effects of negative affect (anxiety, depression) and more coping motivated opioid use.

RESULTS

After controlling for pain severity and relevant demographics, co-use remained related to more anxiety, depression, and opioid-related problems (but not more opioid use). Further, co-use was indirectly related to more opioid-related problems via the serial effect of negative affect (anxiety, depression) and coping motives. Alternative model testing found co-use was not indirectly related to anxiety or depression via serial effects of opioid problems and coping.

CONCLUSIONS

Results highlight the important role negative affect may play in opioid problems among individuals with CLBP who co-use opioid and cannabis.

Posttraumatic Stress, Alcohol Use, and Alcohol Use Motives among Non-Hispanic Black/African American College Students: The Role of Emotion Regulation

OBJECTIVE

The associations between posttraumatic stress disorder (PTSD) symptom severity, alcohol use, and alcohol use motives are well-established. Emotion regulation difficulties have been implicated in the association between PTSD symptoms and alcohol use. A dearth of empirical work, however, has examined these associations among Black/African American college students, a population with high prevalence of exposure to potentially traumatic events, PTSD symptomatology, and alcohol-related consequences.

METHODS

This study examined PTSD symptoms, emotion regulation difficulties, and alcohol use severity and motives among a sample of Black/African American trauma-exposed college students (N = 282; 77.4% identified as female; M age = 22.36, SD = 4.71).

RESULTS

PTSD symptom severity was related to alcohol use and coping and conformity motives for alcohol use through heightened emotion regulation difficulties. Findings were significant above and beyond the effects of trauma load (i.e., number of potentially traumatic event types experienced).

CONCLUSIONS

This study extends past work to an understudied population and contributes to groundwork for culturally informed interventions.

Feasibility, Acceptability, and Efficacy of Mindfulness Training in People With Upper Motor Neuron Disorders: A Systematic Review

OBJECTIVES

This systematic review aims to gain a comprehensive understanding of the feasibility, acceptability, and efficacy of mindfulness-based interventions (MBIs) on depression, anxiety, fatigue, and health-related quality of life among individuals with upper motor neuron disorders (UMNDs).

DATA SOURCES

PubMed, PsycINFO, Excerpta Medica Database, and Cumulative Index to Nursing and Allied Health Literature were searched for relevant studies published between January 2001 and June 2021.

STUDY SELECTION

Clinical trials published in English evaluating MBIs in adults with the 4 most common UMNDs (multiple sclerosis, brain injury including stroke, spinal cord injury, amyotrophic lateral sclerosis) were included.

DATA EXTRACTION

Two reviewers independently performed the risk of bias assessment using standardized tools and extracted desired data electronically.

DATA SYNTHESIS

A total of 44 studies were included: 26 randomized controlled trials, 10 nonrandomized controlled trials, and 8 pre-post intervention studies. The average ± SD duration of MBIs was 8±2 weeks. On average, 85%±14% of participants completed the MBI, and the retention rate at follow-up was 80%±16%. Only 14% of the studies delivered MBIs virtually, and feasibility metrics were similar to in-person studies. Among studies reporting acceptability data, most participants reported satisfaction with the MBI. Randomized controlled trials that evaluated the effects of MBI on depression, anxiety, fatigue, and quality of life revealed greater relative improvement in these outcomes among MBI participants compared with controls, with differences greater when compared with passive control than active control participants. None of the studies included in this review studied dose response.

CONCLUSIONS

Based on current data, MBIs are feasible and offer a promising approach to address the biopsychosocial needs of individuals with UMNDs. MBIs are associated with a high acceptance rate among participants, with notable improvements in depression, anxiety, fatigue, and quality of life post intervention. Future studies are needed to evaluate alternate models of delivery of MBIs and the dose-response relationship.

Motives and Consequences of Alcohol Use in People With Social Anxiety Disorder: A Daily Diary Study

People with social anxiety disorder (SAD) are at increased risk for alcohol-related problems. Most research exploring social anxiety and alcohol use has examined negative drinking consequences, with less consideration of positive consequences-namely positive social experiences-that may reinforce alcohol use. In this daily diary study, we examined how adults diagnosed with SAD (N = 26) and a psychologically healthy control group (N = 28) experienced positive drinking consequences in naturally occurring drinking episodes during the study period. For 14 consecutive days, participants answered questions about alcohol use, motives for drinking, and positive consequences of drinking. On days when participants drank, those with SAD were more likely than healthy controls to perceive a reduction in anxiety, but the two groups did not differ in their likelihood of experiencing positive social drinking consequences. For both groups, on days when they were more motivated to drink to enhance social experiences (affiliation motives) or cope with distress (coping motives), they were more likely to obtain positive consequences from drinking. Compared to controls, participants with SAD endorsed stronger trait and daily coping motives (anxiety-coping, social anxiety-coping, and depression-coping). Results are discussed in the context of reinforcement mechanisms that may maintain social anxiety and alcohol use.

Racial Discrimination and Hazardous Drinking among Black Drinkers: The Role of Social Anxiety in the Minority Stress Model

Objective: Black Americans who consume alcohol experience worse alcohol-related outcomes. Thus, identifying psycho-sociocultural factors that play a role in hazardous drinking among Black individuals is vital to informing prevention and treatment efforts to reduce these disparities. Racial discrimination is related to hazardous drinking among Black adults, suggesting that some may drink (and continue to drink despite drinking-related problems) to alleviate negative affect (e.g., depression, anxiety) associated with discrimination. Yet, despite the social nature of both racial discrimination and drinking, no known research has examined the role of social anxiety in the relations among racial discrimination experiences and hazardous drinking. Method: Participants were 164 Black current drinking undergraduates. Results: Racial discrimination was significantly, positively correlated with hazardous drinking, depression, and social anxiety. Discrimination was indirectly related to hazardous drinking via social anxiety, but not depression. Further, discrimination was indirectly related to hazardous drinking via social anxiety alone and via the sequential effects of social anxiety and drinking to cope, but not via coping motives alone. It was also related to hazardous drinking via the sequential effects of depression and drinking to cope but not depression alone. Alternative model testing indicated that social anxiety was not related to hazardous drinking via discrimination, strengthening confidence in directionality of proposed relations. Conclusions: Negative affect (social anxiety, depression) appears to be related to hazardous drinking among those who experience more discrimination due in part to drinking to cope. Social anxiety plays an important role in the relation between discrimination and hazardous drinking among Black adults.
