Effects of social anxiety and alcohol expectancies on stress-induced drinking.

The utility of trait social anxiety and alcohol expectancies in predicting increased alcohol consumption under socially stressful conditions was investigated. Forty-two male and 42 female undergraduates participated in a 2-day study, serving as their own controls. In each session, participants consumed their preferred alcoholic beverage during a 30-min drinking period. The lst session established baseline consumption under nonstressful conditions, while in the 2nd session, participants drank while anticipating the required delivery of a speech. Measures of social anxiety and alcohol expectancies were completed. Participants consumed more absolute alcohol during the stressful session, but those with high trait social anxiety and men expecting alcohol to increase assertiveness were most likely to show this effect. These findings suggest specificity in the connection between individual characteristics and stress-induced drinking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Similarities between chronic pain and tinnitus

This study was designed to investigate perceptions and metaperceptions of individuals in a mixed sex dating situation in which they were offered alcohol. Male and female participants who were unfamiliar with one another were brought together in individual sessions and asked to imagine that they were on a blind date. At the outset of the 15-minute interaction, they each had an opportunity to select an alcoholic or nonalcoholic drink; after receiving their drink, they interacted privately. At the conclusion of the interaction, participants completed questionnaires that solicited their view of their partner and their perception of their partner's view of them. Results indicate that alcohol expectancies predicted alcoholic beverage selection. When women selected alcohol, they found their partner more likeable; those men whose partner was drinking believed that their partner found them more likeable. Additionally, when both partners were drinking they perceived each other as more extroverted, although they did not think their partner perceived them as extroverted. These results are discussed in terms of implications for further research on the role of alcohol as a cue in a mixed-sex social/dating environment.     

Sex-related alcohol expectancies among adolescents: II. Prediction of drinking in social and sexual situations.

Used a measure developed by K. H. Dermen and M. L. Cooper (see record 1995-07934-001) to test the relationship between sex-related alcohol expectancies and drinking in social and sexual situations among a representative sample of 874 sexually experienced adolescents (aged 13–19 yrs) who had ever consumed alcohol. Regression analyses (in which demographics and a global measure of drinking were controlled for) revealed that sex-related alcohol expectancies were better predictors of drinking in sexual situations than were general alcohol expectancies, whereas the reverse was true for drinking in social situations. Different expectancies predicted whether respondents drank in these situations as compared with the frequency of drinking to intoxication in the same situations. Results highlight the value of assessing domain-specific alcohol expectancies when predicting alcohol use in particular situations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol expectancy priming and drinking behavior: The role of compatibility between prime and expectancy content.

According to information-processing models of alcohol use, alcohol expectancies constitute representations in long-term memory that may be activated in the presence of drinking-related cues, thereby influencing alcohol consumption. A fundamental implication of this approach is that primed expectancies should affect drinking only for those individuals who possess the specific expectancies primed. To test this notion, in the present study, participants were initially assessed on 3 distinct domains of positive alcohol expectancies. Approximately 1 week later, they completed an ad libitum drinking study during which only a single expectancy domain (sociability) was primed in the experimental condition. Consistent with predictions, following exposure to sociability primes but not control primes, individuals with stronger expectancies that alcohol would enhance sociability uniquely showed increased placebo consumption of nonalcoholic beer. These results, which demonstrate the moderating role of compatibility between the specific content of primes and that of underlying expectancies, offer new, direct support for memory network-based models of drinking behavior.

Effect of anxious affect on drinking self-efficacy in college students.

This study examined the role of anxious affect on drinking self-efficacy in undergraduates. Participants (N?=?73) were blocked on dispositional levels of social anxiety and randomly assigned to a social-anxiety-inducing or control condition in a 2?*?2 design. Results did not show the hypothesized interaction effect between dispositional social anxiety and the anxiety manipulation on self-efficacy for avoiding heavy drinking but did demonstrate a main effect of dispositional social anxiety on self-efficacy in situations characterized by negative affect. Significant correlations were found between alcohol expectancies of social facilitation, social anxiety, and self-efficacy for avoiding heavy drinking. Theoretical implications regarding sources of efficacy and the development of interventions for high-risk drinkers are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gender, Alcohol Consumption, and Differing Alcohol Expectancy Dimensions in College Drinkers.

Examinations of gender differences in alcohol expectancies among college drinkers typically have used self-report measures to assess single expectancy dimensions and often have been confounded by drinking level. This study examined gender differences in alcohol expectancies using 2 assessment methods. College students (N = 88) completed self-report questionnaires, including expectancy likelihood and subjective evaluation endorsements of expectancies, and a computerized expectancy accessibility task. Expectancy accessibility and endorsement were modestly correlated, with higher alcohol consumption and female gender linked to greater accessibility and endorsement of social enhancement expectancies. Gender moderated the relation between consumption and sociability expectancy accessibility; among men, heavier drinking was associated with more rapid activation of expectancies. Findings suggest complexity in associations among these variables and underscore the need to capture the multidimensionality of the expectancy construct and its relationship to alcohol use.

Parents, peers, and prototypes: Antecedents of adolescent alcohol expectancies, alcohol consumption, and alcohol-related life problems in rural youth.

Most research on alcohol consumption has considered the impact of social influences, such as parental and peer factors, separately from more cognitive factors, such as alcohol expectancies. No research to date has prospectively considered the antecedents to alcohol expectancies and how they may relate to other alcohol-related cognitions (e.g., risk images). Using a recently developed model of health behavior in a longitudinal study with a sample of 357 adolescents and their parents, the current study investigated the combined impact of social, parental, and cognitive factors on alcohol expectancies, consumption, and alcohol-related life problems. Results suggest that parental and social factors are antecedents to expectancies and that cognitive factors mediate the impact of parental influence on consumption.

Alcohol use among college students as a function of their typical social drinking context.

This study investigated the relations among frequency of drinking in different social contexts; alcohol consumption, expectancies, and problems; and psychosocial characteristics among college students. Social drinking contexts were defined by the size and gender composition of social groups. Participants were 98 men and 98 women who endorsed current alcohol use. The results showed that typical social drinking contexts were associated with men's average daily number of drinks and frequency of drunkenness but were not associated with women's alcohol consumption. Controlling for alcohol expectancies and personality factors did not obscure significant social context effects for men's alcohol consumption or problems, supporting the importance of considering social context variables in studies of drinking. Future research with regard to alcohol education, intervention, and prevention strategies is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol primes, expectancies, and the working self-concept.

Previous research has shown that alcohol consumption can lead to momentary changes in the self-concept (e.g., Steele & Josephs, 1990). In two studies (n = 150), we examined whether the implicit activation of alcohol expectancies (i.e., sociability-related expectancies) would also lead to changes in self-perception. To test this idea, participants first completed a measure of sociability-related alcohol expectancies. In a subsequent laboratory session, participants were exposed to either alcohol-related primes (i.e., pictures or words associated with alcohol) or neutral primes. After the priming task, participants completed an ostensibly unrelated self-concept survey that contained words related to sociability (e.g., “outgoing”) and nonsociability related words (e.g., “clever”). For both studies, results revealed that sociability-related alcohol expectancies were positively associated with sociability-related self-concept ratings for participants exposed to alcohol primes, but not for participants exposed to the neutral primes. Implications for the role implicit self-concept activation may have on drinking behaviors are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol expectancies and their relationship to actual drinking experiences.

44 undergraduate normal drinkers participated in a social task in drinking and nondrinking conditions and rated their subjective experiences and their perception of experiences of other group members along 7 alcohol expectancy dimensions. In the drinking condition, Ss rated their experiences as being positively enhanced on those dimensions predicted by the expectancy literature, but did not report experiencing the negative cognitive and motor effects associated with alcohol consumption. It is concluded that in social situations, individuals' alcohol expectancies and experiences coincide for socially relevant variables, but do not for variables related to cognitive skills.

Age and drinking-related differences in the memory organization of alcohol expectances in 3rd-, 6th-, 9th-, and 12th-grade children.

To advance the theoretical modeling of the development of alcohol expectancies as a parallel processing memory network, this study assessed expectancies and alcohol consumption of 2,324 children in Grades 3, 6, 9, and 12 from a large suburban-rural school district. Individual-differences scaling (INDSCAL), a variant of multidimensional scaling, mapped expectancies into a hypothetical memory network format, and preference mapping (PREFMAP) modeled hypothetical paths of association within this network. Throughout this age range, older and higher drinking youth appeared to associate positive and arousing effects with alcohol cues, in contrast to lower drinking children, who appeared to mainly associate undesirable effects. These drinking-related differences in the organization of expectancy information are discernible well before onset of regular drinking habits and may influence the development of drinking in adolescence.

ALDH2, ADH1B and alcohol expectancies: Integrating genetic and learning perspectives.

The present study evaluated associations of ALDH2 and ADH1B genotypes with alcohol expectancies and drinking behavior in a sample of Asian American young adults. In addition to assessing global alcohol expectancies, the authors developed a measure of physiological expectancies to evaluate an expectancy phenotype specific to the mechanism by which ALDH2 and ADH1B variations presumably influence drinking behavior. Compared with individuals with the ALDH2*1/*1 genotype, those with the ALDH2*2 allele reported greater negative alcohol expectancies, greater expectancies for physiological effects of alcohol and lower rates of alcohol use. ADH1B was not associated with alcohol expectancies or drinking behavior. Hierarchical models showed that demographic factors, ALDH2 genotype, and expectancy variables explained unique variance in drinking outcomes. Mediation tests showed significant indirect effects of ALDH2 on drinking frequency and peak lifetime consumption through expectancies. These results provide support for influences of genetic factors and alcohol sensitivity on alcohol-related learning and suggest the importance of developing biopsychosocial models of drinking behavior in Asian Americans.

Detection of K-ras point mutations in the supernatants of peritoneal and pleural effusions for diagnosis complementary to cytologic examination

OBJECTIVE: The present study aimed to examine the discriminatory ability of alcohol expectancies and drinking refusal self-efficacy and to identify the differential role of these constructs in social and problem drinkers. METHOD: Drinkers (N = 276) were self-selected from general (n = 185) and clinical (n = 91) populations to complete a 40-minute questionnaire that asked about alcohol expectancies, drinking refusal self-efficacy, consumption, degree of dependence and demographics. RESULTS: The results showed that in social drinkers both the expectancy and self-efficacy constructs were reliably able to discriminate between types of drinker. Expectancy was related to consumption in social drinkers, but did not appear to account for a significant proportion of the variance in problem drinkers. CONCLUSIONS: The findings are discussed in terms of a two-process model of drinking behavior that suggests that expectancies operate differently in social and problem drinkers.     

Effects of a brief motivational intervention with college student drinkers.

This study consisted of a randomized controlled trial of a 1-session motivational intervention for college student binge drinkers. Sixty students who reported binge drinking 2 or more times in the past 30 days were randomly assigned to either a no-treatment control or a brief intervention group. The intervention provided students with feedback regarding personal consumption, perceived drinking norms, alcohol-related problems, situations associated with heavy drinking, and alcohol expectancies. At 6-week follow-up, the brief intervention group exhibited significant reductions on number of drinks consumed per week, number of times drinking alcohol in the past month, and frequency of binge drinking in the past month. Estimates of typical student drinking mediated these reductions. This study replicates earlier research on the efficacy of brief interventions with college students and extends previous work regarding potential mechanisms of change.

Expectancies versus background in the prediction of college drinking patterns.

Examined the alcohol expectancies of 321 17–40 yr old undergraduates as a function of Ss' drinking patterns and Ss' expectancies to demographic/background variables for their ability to predict problematic and nonproblematic drinking patterns. Ss completed a demographic data sheet, alcohol expectancy questionnaire, and customary drinking record. Factor analysis of Ss' self-reported drinking yielded 3 drinking styles: nonproblematic social drinking, frequent drinking with alcohol-related problems, and contextually determined alcohol consumption. Optimal alcohol expectancy and demographic/background predictors of each drinking style were selected and compared via multiple regression procedures. Predictor equation efficiency was then examined in a new cross-validation sample of 176 Ss. Results indicate that alcohol expectancies increased the predictability of college drinking patterns and that alcohol expectancies were differentially related to problematic and nonproblematic features of college drinking.

Correction to Leeman, Toll, Taylor, and Volpicelli (2009).

Reports an error in "Alcohol-induced disinhibition expectancies and impaired control as prospective predictors of problem drinking in undergraduates" by Robert F. Leeman, Benjamin A. Toll, Laura A. Taylor and Joseph R. Volpicelli (Psychology of Addictive Behaviors, 2009[Dec], Vol 23[4], 553-563). The table headings in Table 5, p. 561 should have read “Time 2 alcohol related problems” and “Time 2 heavy episodic drinking”. (The following abstract of the original article appeared in record 2009-24023-001.) Trait disinhibition is associated with problem drinking and alcohol drinking can bring about a state of disinhibition. It is unclear however, if expectancies of alcohol-induced disinhibition are unique predictors of problem drinking. Impaired control (i.e., difficulty in limiting alcohol consumption) may be related to disinhibition expectancies in that both involve issues of control related to alcohol use. Data from a prospective survey of undergraduates assessed during freshman (N = 337) and senior year (N = 201) were analyzed to determine whether subscales of the Drinking-Induced Disinhibition Scale (Leeman, Toll, & Volpicelli, 2007) and the Impaired Control Scale (Heather et al., 1993) predicted unique variance in heavy episodic drinking and alcohol-related problems. In Time 1 cross-sectional models, Dysphoric disinhibition expectancies predicted alcohol-related problems and impaired control predicted both alcohol-related problems and heavy episodic drinking. In prospective models, Time 1 impaired control predicted Time 2 alcohol-related problems and Time 1 Euphoric/social Disinhibition expectancies predicted Time 2 heavy episodic drinking. These findings suggest that expectancies of alcohol-induced disinhibition and impaired control predict unique variance in problem drinking cross-sectionally and prospectively, and that these phenomena should be targeted in early intervention efforts.

Influence of naltrexone on cue-elicited craving among hazardous drinkers: The moderational role of positive outcome expectancies.

This study was designed to elucidate mechanisms by which naltrexone (NTX) influences drinking among hazardous drinkers. Thirty-six hazardous drinkers received 50 mg NTX or placebo on 2 separate occasions before participation in a taste test procedure with low-alcohol beer. Urges to drink before consumption, beer volume consumed, and perceived stimulation and sedation after consumption were assessed. Although NTX did not influence beer consumption, hazardous drinkers who reported high positive reinforcement expectancies rated their urges to drink as significantly lower when they were on NTX compared with placebo. Positive outcome expectancies also moderated the effects of NTX on subjective reports of stimulation following drinking. These findings suggest that naltrexone may be particularly effective at reducing alcohol cue-elicited positive reinforcement for those with high positive alcohol outcome expectancies.

Fitting in and feeling fine: Conformity and coping motives as mediators of the relationship between social anxiety and problematic drinking.

The present research was conducted to clarify the relationships among social anxiety, alcohol consumption, alcohol-related problems, and negative-reinforcement drinking motives among college students. Heavy drinking students (N = 316, 53.80% female) completed self-report measures of social anxiety, alcohol consumption, alcohol-related problems, and drinking motives. Findings indicated that students higher in social anxiety consumed less alcohol but experienced more negative consequences. Moreover, the relationship between social anxiety and negative consequences was mediated by coping and conformity drinking motives in addition to alcohol consumption. In the context of social anxiety, the current research demonstrates the importance of examining problematic drinking as distinct constructs: alcohol consumption and negative consequences. Findings are also discussed in terms of implications for interventions with socially anxious students. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reactivity to Alcohol-Related Cues: Relationship Among Cue Type, Motivational Processes, and Personality.

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray's (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray's model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.
