Attentional bias toward negative social cues is thought to serve an etiological and/or maintaining role in social anxiety disorder (SAD). The current study tested whether training patients to disengage from negative social cues may ameliorate social anxiety in patients (N = 36) with a primary diagnosis of generalized SAD. Patients were randomly assigned to either an attention training condition (n = 18), in which patients completed a modified dot-probe task designed to facilitate attentional disengagement from disgusted faces, or a control dot-probe task condition (n = 18). As predicted, patients in the attention training condition exhibited significantly greater reductions in social anxiety and trait anxiety, compared with patients in the control condition. At termination, 72% of patients in the active treatment condition, relative to 11% of patients in the control condition, no longer met Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for SAD. At 4-month follow-up, patients in the attention training condition continued to maintain their clinical improvement, and diagnostic differences across conditions were also maintained. Results support attention-based models of anxiety and suggest that attention training is a promising alternative or complementary intervention.
Social anxiety disorder (SAD) is highly comorbid with alcohol use disorders (AUDs) and cannabis dependence. However, the temporal sequencing of these disorders has not been extensively studied to determine whether SAD serves as a specific risk factor for problematic substance use. The present study examined these relationships after controlling for theoretically-relevant variables (e.g., gender, other Axis I pathology) in a longitudinal cohort over approximately 14 years. The sample was drawn from participants in the Oregon Adolescent Depression Project. After excluding those with substance use disorders at baseline, SAD at study entry was associated with 6.5 greater odds of cannabis dependence (but not abuse) and 4.5 greater odds of alcohol dependence (but not abuse) at follow-up after controlling for relevant variables (e.g., gender, depression, conduct disorder). The relationship between SAD and alcohol and cannabis dependence remained even after controlling for other anxiety disorders. Other anxiety disorders and mood disorders were not associated with subsequent cannabis or alcohol use disorder after controlling for relevant variables. Among the internalizing disorders, SAD appears to serve as a unique risk factor for the subsequent onset of cannabis and alcohol dependence.
Given the high rates of co-occurring marijuana use and social anxiety, the present investigation examined the relations among marijuana use motives, marijuana use and problems, and social anxiety in 159 (54.7% female) young adults (M(age)=18.74, SD=1.20). As expected, after covarying for a number of variables related to both marijuana use and social anxiety (e.g. gender, alcohol use problems, anxiety sensitivity), social anxiety predicted greater numbers of marijuana use problems. Interestingly, social anxiety was not related to marijuana use frequency. Also consistent with prediction, social anxiety was a significant predictor of coping and conformity motives for marijuana use above and beyond relevant variables. Finally, coping motives for marijuana use mediated the relation between social anxiety and marijuana use problems. These data provide novel evidence for the unique effects of coping-motivated marijuana use in the link between marijuana-related impairment and social anxiety.
Problematic substance use is associated with depression. Clarifying the relationship between substance use and depression remains an important research goal, with implications for prevention and treatment. Individual differences in the ability to tolerate negative physical and emotional sensations were hypothesized to play a role in substance use behaviors among depressed individuals. The present study investigated the roles of discomfort and distress tolerance in the relationship between alcohol and cannabis problems and depression among undergraduates (N = 265). Consistent with other reports, depression was correlated with alcohol and cannabis problems. As predicated, distress tolerance mediated the relationships between depression and alcohol and cannabis problems. Interestingly, discomfort intolerance moderated the relationship between depression and cannabis problems such that depressed individuals with high discomfort tolerance were most vulnerable to cannabis problems. These data suggest that distress intolerance may at least partially account for alcohol and cannabis problems among depressed young adults whereas discomfort intolerance may actually serve a protective role in the development of cannabis problems. KeywordsMarijuana; Cannabis; Alcohol; Depression; Distress Intolerance; Discomfort Intolerance Alcohol use disorders (AUD) and illicit substance use disorders (SUD) are associated with high rates of depression (Grant et al., 2003). Depression is associated with a two-fold increase in the rate of AUD (Grant et al., 2004;Grant et al., 2003) and a six-fold increase in the rate of cannabis use disorder (Grant, 1995). Despite the high rates of AUD and SUD among depressed individuals, the mechanisms underlying these relations remain unclear. Individual differences in the ability to tolerate negative emotional and physical sensations could help explain these linkages. Distress intolerance is a decreased capacity to withstand negative emotional states and has been linked to substance misuse . There is good reason to believe distress intolerance may at least partially account for substance problems in depressed individuals. To illustrate, using alcohol to cope with psychological distress mediates the link between negative affect regulation expectancies and alcohol use (Galen, Henderson, & Coovert, 2001). Comparable relations have been found for cannabis use (Simons, Gaher, Correia, Hansen, & Christopher, 2005).* Correspondence concerning this article should be addressed to Norman B.

High social anxiety is related to marijuana problems, yet the nature of this relation remains unclear. We examined relations between marijuana effect expectancies, social anxiety, and marijuana among undergraduates (N=337). Social anxiety was related positively to negative expectancies and negatively to Tension Reduction Expectancies. Among socially anxious individuals, greater belief that marijuana produces cognitive/behavioral impairment was associated with greater marijuana use rates. Negative expectancies mediated the social anxiety-marijuana problems link. These data provide new insight into problematic marijuana use among this high-risk group.
Background and Objectives Marijuana remains the most commonly used illicit substance. Marijuana craving, anxiety, and peer marijuana use are thought to play important roles in the etiology and maintenance of marijuana use. The present study aimed to identify patterns between marijuana use and these affective and situational risk factors in the natural environment. Methods The sample consisted of 49 current marijuana users (38.8% female), 63.2% of whom evinced a current cannabis use disorder. Ecological momentary assessment was used to collect multiple daily ratings of marijuana craving, state anxiety, and peer marijuana use over two weeks. Mixed effects linear models were used to examine within- and between-day antecedents, correlates, and consequences of marijuana use. Results Between-day analyses indicated that marijuana use days were associated with higher marijuana craving but lower state anxiety. Within-day analyses confirmed that marijuana craving was higher prior to marijuana use and lower following use. Anxiety was related to marijuana craving. Although anxiety was somewhat higher prior to marijuana use, it did not decrease significantly following use. The vast majority of marijuana use occurred when others were also using marijuana. Limitations The sample was comprised of college students, a group at particular risk for marijuana use and use-related problems. Future work is necessary to determine whether results generalize to other populations. Conclusions These data support the contention that marijuana craving, anxiety, and peer use play important roles in the maintenance of marijuana use.
Emerging evidence suggests that elevated anxiety sensitivity (AS) is associated with substance use disorders. However, prospective evidence regarding this association is currently lacking. The primary aim of the present study was to determine whether AS is involved in the pathogenesis of substance-related psychopathology. A large, nonclinical sample of young adults (N = 404) was prospectively followed for approximately 2 years. AS (i.e., 16-item Anxiety Sensitivity Index total scores) at study entry and gender served as the primary predictor variables. Findings indicated that AS was uniquely associated with the later development of alcohol use disorder diagnoses. Data indicated that gender and AS did not act synergistically to predict alcohol use disorders. These data provide novel evidence for the unique effects of AS as a prospective risk factor in the development of alcohol-related disorders.
