BACKGROUND Several hypotheses exist to account for the higher than normal rate of alcoholism in individuals with high trait anxiety (or anxiety disorders). Most of these suggest that the practice of drinking alcohol to reduce anxiety leads to an increased risk of alcoholism in vulnerable individuals. The first assumption of the hypothesis is that anxious individuals use alcohol to cope with their anxiety. Few studies have examined this issue systematically, and none have used a nonanxious matched control group. METHODS Twenty-three individuals with high social anxiety and 23 nonsocially anxious matched controls were included in the study. Groups were similar on demographic variables and alcohol use. All participants were queried regarding the use of alcohol to cope, the practice of avoiding social situations if alcohol was not available, and the degree of relief attained by alcohol. Participants also were asked about using alcohol in 11 specific situations. RESULTS The socially anxious group was significantly more likely than controls to report using alcohol to feel more comfortable in social situations and to avoid social situations if alcohol was unavailable. They also reported a greater degree of relief of anxiety from alcohol. Exploratory analyses revealed that socially anxious individuals reported using alcohol more to cope with social interactions than with social performance situations. CONCLUSIONS Individuals high in social anxiety deliberately drink alcohol to cope with their social fears. They report that alcohol is moderately effective at reducing their anxiety, which is seemingly sufficient to allow them to endure social situations. The data support the first assumption of the self-medication hypothesis-that alcohol is used to reduce social discomfort in socially anxious individuals; however, the study was not designed to address the veracity of the self-medication hypothesis as a whole. Results can help guide future studies that examine the relationship between social anxiety and alcohol.

Opiate antagonist medications have been shown to improve alcoholism treatment, but few human laboratory-based studies investigating mechanisms for these effects have been conducted on alcohol dependent persons. The present study was designed to determine the impact of two opiate antagonists on alcohol consumption among nontreatment-seeking alcoholics (n=125) and social drinkers (n=90). Participants were randomly assigned to receive placebo, naltrexone (titrated to 50 mg/day), or nalmefene (titrated to 40 mg/day) for 8 days with an alcohol laboratory session on the final day. Alcohol consumption was monitored in the natural environment during the first 5 medication days, and during a choice consumption paradigm following a standard ‘priming’ alcohol dose in a bar–laboratory setting. Social drinkers consumed less alcohol than alcoholics during the prelab medication period and the laboratory choice consumption paradigm, and they attained lower blood alcohol levels than alcoholics following the priming drink. Both opiate antagonist medications equally reduced drinking amounts and frequency among alcoholics but not social drinkers, relative to placebo, during natural environment and bar–lab alcohol consumption evaluations. Greater medication side effects, mostly mild in nature, were observed in participants taking nalmefene. These findings demonstrate that both naltrexone and nalmefene can lead to reductions in alcohol consumption among alcoholics who are not attempting to reduce drinking. Similar laboratory paradigms may offer substantial advantages for observing these effects during evaluation of other medications as well.

Repeated use of alcohol as a coping strategy to reduce anxiety or discomfort increases ones risk of developing alcohol dependence. Previous studies have found alcohol outcome expectancies (AOE) strongly predict drinking behavior, in general, and also are related to drinking to cope. The purpose of the current study was to examine AOE that may be related to drinking to cope with discomfort in social situations. It was hypothesized that positive AOE, especially related to assertion and tension reduction, would be most associated with drinking to cope with social situations. Fifty-six community volunteers from a larger study on attentional bias and drinking to cope were divided into high (n=36) and low (n=20) drinking to cope groups following completion of a questionnaire battery. Findings indicated AOE were well able to classify drinking to cope status, with 91% of cases correctly classified. As hypothesized, assertion and tension reduction AOE uniquely contributed to the discriminant function in classifying drinking to cope groups. These findings have implications for the prevention and treatment of alcohol use disorders and suggest that AOE should be further investigated as potential moderators of the relationship between social anxiety and alcohol use disorders.

The present study was conducted to test the hypothesis that socially phobic alcoholics treated with Cognitive Behavioral therapy (CBT) will have better drinking outcomes than those treated with Twelve-Step Facilitation therapy (TSF). Three hundred ninety-seven treatment-seeking alcoholics with concurrent social phobia were compared retrospectively to a matched sample of 397 alcoholics without social phobia. Treatment was delivered in an outpatient setting, and patients were randomized to either CBT, TSF, or Motivational Enhancement therapy (MET). The groups were compared on self-reported drinking measures (e.g., quantity and frequency of drinking, and time-to-event measures) during treatment period and monthly for 1 year following treatment. Survival analyses revealed that female outpatients with social phobia showed delayed relapse to drinking when treated with CBT rather than TSF; the reverse was true for female outpatients without social phobia. Survival analyses in male outpatients with and without social phobia revealed an opposite trend, though it was not statistically significant. These data suggest that Cognitive Behavioral therapy is superior to Twelve-Step Facilitation therapy for the treatment of alcohol problems in specific populations. namely socially phobic women seeking outpatient treatment.

RationaleCue-elicited craving and stress responses have been identified as predictors of relapse in drug dependence, but little research exists on the contribution of these factors to marijuana use specifically.ObjectivesThe aims of the present study were to evaluate (1) responses to a psychological stressor, (2) responses to marijuana-related cues, and (3) if an exposure to a psychological stressor augmented craving subsequently elicited by marijuana-related cue exposure in marijuana-dependent individuals.MethodsSubjective (craving, stress), neuroendocrine (adrenocorticotropic hormone (ACTH), cortisol), and physiologic responses to the presentation of neutral and marijuana cues were assessed after randomization to a stress (Trier Social Stress Task (TSST)) or non-stress control condition in marijuana-dependent individuals. Outcome measures were assessed at baseline, post-stressor/pre-neutral cue, post-neutral cue, and post-marijuana cue.ResultsEighty-seven participants completed procedures (stress group, n = 45; non-stress group, n = 42). The stress group had a significant increase over the non-stress group in stress rating (p < 0.001), craving (p = 0.028), cortisol (p < 0.001), and ACTH (p < 0.001) after the completion of the TSST. An increased craving response for all participants was seen following the presentation of the marijuana cues (p = 0.005). Following the TSST or non-stress condition, the non-stress group had an increase in craving to marijuana cues as compared to neutral cues (p = 0.002); an increase in craving was not observed in the stress group (p = 0.404).ConclusionsMarijuana cue exposure and a social stressor increased craving in marijuana-dependent individuals. Completion of the TSST did not increase craving response to subsequent marijuana cue exposure.

Individuals with social anxiety have difficulty participating in group settings. Although it makes intuitive sense that social anxiety could present a challenge in addiction treatment settings, which often involve small groups and encouragement to participate in self-help groups like Alcoholics Anonymous (AA) and Narcotics Anonymous (NA), to our knowledge no study has yet assessed the impact of shyness on the treatment experience. Assessment surveys were given to 110 individuals seeking intensive outpatient substance abuse treatment at three community treatment programs. Established cut-offs for presence of clinically-significant social anxiety indicated a prevalence of 37%. Controlling for depression and worry, social anxiety was a unique predictor of endorsement that shyness interfered with willingness to talk to a therapist, speak up in group therapy, attend AA/NA, and ask somebody to be a sponsor. Socially anxious substance abusers were 4-8 times more likely to endorse that shyness interfered with addiction treatment activities. These findings have clinical and research implications.

BACKGROUND Relapse risk factors, such as psychological stress and alcohol cues, are often encountered together. Understanding how they interact has the potential to improve alcoholism treatments. This study was conducted to examine whether an acute psychosocial stressor enhanced alcohol cue reactivity in non-treatment-seeking alcoholics. METHODS Seventy-nine alcohol-dependent individuals (39 women) randomly received either the Trier Social Stress Test or a no-stress control condition. Stress reactivity was measured with serum adrenocorticotropic hormone and cortisol, mean arterial blood pressure, and subjective distress. Immediately following the stress manipulation, participants held and sniffed a neutral cue then their preferred alcoholic beverage. Cue reactivity was measured by 2 subjective measures of craving following each cue. Additionally, general craving was assessed with the Alcohol Urge Questionnaire at the beginning and end of the laboratory procedure. RESULTS The stress manipulation showed internal validity on all measures of stress reactivity. There was not a main effect of stress nor a stress × cue interaction on either cue reactivity measure. As expected, there was a main effect of cue (alcohol > neutral cue) on both measures of cue reactivity. General craving increased during the challenge, but not differently by stress group. Magnitude of stress reactivity was not associated with magnitude of cue reactivity, and all results were independent of gender. CONCLUSION In this well-controlled clinical laboratory study of non-treatment-seeking alcoholics, an acute psychological stressor did not make an alcohol cue a more potent urge-inducing stimulus, and stress had no effect on general alcohol craving.

Using alcohol to cope (i.e., coping motivation) and general coping style both are theorized and demonstrated empirically to lead to problematic drinking. In the present study, we sought to examine whether these factors interact to predict alcohol use, both retrospectively reported and in the lab following a stressor task. Social drinkers (N=50, 50% women) received the Trier Social Stress Test (TSST), and then consumed beer under the guise of a taste test. A Timeline Followback interview to assess past month alcohol use, the Drinking Motives Questionnaire (DMQ), and the COPE (to assess adaptive coping) were administered prior to the laboratory challenge. Multiple regression models were used to examine DMQ coping motives, adaptive coping, and their interaction as predictors of milliliters (mls) of beer consumed in a clinical laboratory setting. The association between coping motives and mls beer was positive at both high and low levels of adaptive coping, but at low levels of adaptive coping, this association was stronger. In contrast, there was no interaction between adaptive coping and coping motives in predicting quantity and frequency of drinking in the prior month. Findings suggest that stronger coping motives for drinking predict greater alcohol consumption following a stress provocation to a greater extent when an individual is lacking in adaptive coping strategies. As both general coping skills and coping motives for alcohol use are responsive to intervention, study of the conditions under which they exert unique and interactive effects is important.

Differences on demographics and seven measures of social support between matched, treatment-seeking alcoholics with and without social phobia (SP and NSP groups, respectively) were examined. The groups did not differ on most demographic variables, although the SP group (n = 397) had a lower occupational status and had fewer years of education (both ps <.01) than the NSP group (n = 397). On social support measures, the SP group had less perceived social support from friends and had a lower performance on the social behavior role scale than the NSP group (both ps <.001). The two groups were unexpectedly more similar than different on the measures of interest in this study; however, the differences identified are meaningful for treatment planning. It is important to ascertain the quantity and sources of social support which are available to these clients in order to maximize positive treatment outcomes.

Alcoholism pharmacotherapies are underused in community addiction treatment settings, in part because individuals who practice in these settings--nonmedical addiction counselors and administrators--lack knowledge about and confidence in the value of adjunctive alcohol pharmacotherapies. We developed and tested an intervention to improve knowledge and attitudes about naltrexone. A team of researchers, physicians, addiction treatment counselors, and administrators collaborated to develop a naltrexone educational intervention designed for nonmedical addiction professionals. The intervention was compared with a control condition in a pilot study with 6 addiction treatment agencies (3 agencies per group). Participants (counselors and administrators, N = 84) were assessed before and 6 months after the intervention. Results revealed that the intervention significantly improved naltrexone knowledge, and participants who received the intervention reported greater satisfaction with the education they received, as well as greater use of the information. The effect of the intervention on attitudes about naltrexone was encouraging but did not to reach statistical significance. This study is the first reported attempt to develop and test an intervention specifically to improve acceptance of adjunctive medications for alcoholism among nonmedical addiction professionals.
