Drinking behavior in preadolescence is a significant predictor of both short- and long-term negative consequences. This study examined the psychometric properties of 1 known risk factor for drinking in this age group, alcohol expectancies, within an item response theory framework. In a sample of middle school youths (N = 1,273), the authors tested differential item functioning (DIF) in positive and negative alcohol expectancies across grade, gender, and ethnicity. Multiple-indicator multiple-cause model analyses tested differences in alcohol use as a potential explanation for observed DIF across groups. Results showed that most expectancy items did not exhibit DIF. For items where DIF was indicated, differences in alcohol use did not explain differences in item parameters. Positive and negative expectancies also systematically differed in the location parameter. Latent variable scale scores of both positive and negative expectancies were associated with drinking behavior cross-sectionally, while only positive expectancies predicted drinking prospectively. Improving the measurement of alcohol expectancies can help researchers better assess this important risk factor for drinking in this population, particularly the identification of those with either very high positive or very low negative alcohol expectancies.

The best method currently available for predicting adolescent alcohol consumption is to use the significant relationship that has been found between this variable and demographic/background variables. To assess the theoretical and practical utility of adolescent alcohol expectancies, the present authors pitted these expectancies against important demographic/background variables in the prediction of adolescent drinking. This comparison required 3 procedural steps: (a) factor analytic derivation of 3 adolescent drinking styles, (b) multiple regression prediction of these drinking styles using demographic/background variables, and (c) assessment of the predictive power of alcohol expectancies. Ss were 1,580 12–19 yr olds. Results show that expectancies (as measured by the Alcohol Expectancy Questionnaire for Adolescents) at least equalled and even added to the predictive power of the background variables. Specifically, Ss who drank in a frequent, social manner expected alcohol to enhance their social behavior, whereas Ss who reported alcohol-related problems expected an improvement in their cognitive and motor functioning. Results suggest assessment and treatment strategies for high-risk adolescents and indicate a possible mediator of adolescent drinking problems.

Attempts to understand the mechanism by which alcohol expectancies might influence drinking have related activation of expectancies in memory to alcohol use. Limb of the blood alcohol curve, however, has not been considered. In the present study, 527 undergraduates completed the Anticipated Biphasic Alcohol Effects Scale and a drinking measure. Multidimensional scaling was used to map expectancies into memory network format, and likely activation of expectancies was empirically modeled. Heavier drinkers were most likely to activate positive and arousing expectancies associated with the ascending limb, whereas lighter drinkers were most likely to activate negative and sedating expectancies associated with the descending limb. These findings add to the literature suggesting that activation of expectancies in memory may be an important determinant of drinking behavior and a promising target for intervention strategies.

Drinking in elementary school, despite its low base rate, has been shown to predict alcohol use in middle school (Wilson, Battistich, Syme, & Boyce, 2002), which in turn predicts alcohol abuse or dependence in young adults (Guo, Collins, Hill, & Hawkins, 2000). The authors report 1 of the 1st examinations of the relationship between personality and psychosocial learning risk factors and drinking behavior among elementary school students. Fifth-grade students completed measures of disinhibition, positive and negative alcohol expectancies, and drinking. MIMIC modeling, tests of mediation, and tests of moderation were completed to test these relations. It was found that disinhibition and positive alcohol expectancies were each related to drinking in 5th graders. Disinhibition moderated the relation between positive alcohol expectancies and drinking in some cases. Mediation was not supported.

The current study examined alcohol expectancies and drinking motives as correlates of alcohol involvement among adolescents at high and low risk for future alcoholism. Measures of alcohol expectancies, drinking motives, presumed personality risk for alcoholism, family history of alcoholism, and alcohol involvement were completed by 979 high school students. Alcohol expectancies and drinking motives were found to vary as a function of risk status. More important, the strength of the relations between alcohol expectancies or drinking motives and alcohol involvement varied as a function of risk status. Expectancies of altered social behavior were particularly associated with low-risk drinking. Expectancies of enhanced cognitive and motor functioning, expectancies of tension reduction, expectancies of deteriorated cognitive and behavioral functioning, personal motives, and power motives were particularly associated with high-risk drinking. These expectancies and motives are of potential prognostic significance in the development of alcoholism and may be important targets for modification in primary prevention programs.

Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children's drinking behavior in mid-adolescence are mediated by the children's alcohol expectancies in early adolescence. A sample of 148 initially 9–11 year old boys and their parents from a high-risk population and a contrast group of community families completed measures of drinking behavior and alcohol expectancies over a 6-year interval. We analyzed data from middle childhood (M age = 10.4 years), early adolescence (M age = 13.5 years), and mid-adolescence (M age = 16.5 years). The sample was restricted only to adolescents who had begun to drink by mid-adolescence. Results from zero-inflated Poisson regression analyses showed that 1) maternal drinking during their children's middle childhood predicted number of drinking days in middle adolescence; 2) negative and positive alcohol expectancies in early adolescence predicted odds of any intoxication in middle adolescence; and 3) paternal alcoholism during their children's middle childhood and adolescents' alcohol expectancies in early adolescence predicted frequency of intoxication in middle adolescence. Contrary to predictions, child alcohol expectancies did not mediate the effects of parental alcohol involvement in this high-risk sample. Different aspects of parental alcohol involvement, along with early adolescent alcohol expectancies, independently predicted adolescent drinking behavior in middle adolescence. Alternative pathways for the influence of maternal and paternal alcohol involvement and implications for expectancy models of adolescent drinking behavior were discussed.

Experimental research and popular belief suggest that, among its many effects, alcohol consumption reduces tension and facilitates aggression. Such observations could result from direct, pharmacological effects of alcohol on neural control of behavior but also may be accounted for by positing that drinking behavior activates mental representations of relaxation-related or aggression-related alcohol expectancies in long-term memory. Building on this latter view, in 2 experiments, the authors investigated whether rudimentary drinking-related cues, which presumably activate encoded alcohol expectancies, facilitate tension reduction and hostility in the complete absence of actual or placebo alcohol consumption. In Experiment 1, following contextual exposure to alcohol-related words, individuals with stronger expectancies that drinking reduces tension showed an increased willingness to meet with an opposite-gender stranger under relatively anxiety-provoking circumstances, suggesting that they experienced less apprehension regarding the meeting. Analogously, in Experiment 2, following near-subliminal exposure to alcohol-related words, individuals with stronger expectancies that drinking fosters aggression showed greater hostility toward a target person following an experimentally engineered provocation. Neither of the latter effects was obtained following exposure to nonalcoholic beverage words, which presumably did not activate alcohol outcome expectancy representations in long-term memory. Moreover, the strength of relevant, content-specific expectancies (i.e., for tension reduction or aggression, respectively) moderated alcohol cue exposure effects, but the strength of other expectancies (e.g., for sociability or sexual arousal) did not. Together, these findings demonstrate that exposure to rudimentary alcohol cues independently engenders expectancy-consistent behavior, thereby attesting to the remarkable breadth and subtlety of the behavioral impact of alcohol expectancy activation.

Alcohol-related cognitions, particularly expectancies for drinking and nondrinking and motives for nondrinking, are involved in the initiation, maintenance, and cessation of alcohol use and are hypothesized to play key roles in adolescent decision making. This study explored (a) the relationships between alcohol use expectancies, nondrinking expectancies, and nondrinking motives; (b) the roles of these cognitions across hypothesized developmental stages of adolescent alcohol use; and (c) the relationships between these cognitions and recent or intended future changes in drinking behavior in a cross-sectional sample. Surveys assessing alcohol use behaviors and attitudes were administered to 1,648 high school students. Heavier drinkers reported more positive alcohol use expectancies and fewer nondrinking motives than did lighter drinkers or nondrinkers; however, nondrinking expectancies only differed between nondrinkers and rare drinkers and all subsequent drinking classes. Alcohol use expectancies, nondrinking expectancies, and nondrinking motives differentiated students who recently initiated alcohol from those who had not, while nondrinking expectancies and nondrinking motives differentiated binge-drinking students who had made recent efforts to reduce/stop their drinking from those who had not. Intentions to initiate or reduce drinking in the coming month were also associated with these alcohol-related cognitions. Drinking and nondrinking expectancies and motives for not drinking may play critical roles in decisions to alter alcohol-use behavior during adolescence. Future exploration of temporal relationships between changes in alcohol-related cognitions and behavioral decision making will be useful in the refinement of effective prevention and intervention strategies.

Alcohol-related expectancies covary consistently with consumption patterns; limited research also suggests that expectancies can predict future drinking behavior. However, the ability of expectancies to predict high-risk drinking has not been evaluated among college students. Participants were 140 undergraduates who completed an alcohol use assessment at 2 points in time, separated by. 1 month. Using multiple regression analyses, the author determined that alcohol-related expectancies accounted for a small but significant percentage of variance in each of 2 alcohol consumption variables. Global positive expectancies predicted maximum daily quantity, and sexual enhancement expectancies predicted the frequency of intoxication, even when controlling for baseline levels of both variables. These findings support alcohol abuse prevention efforts designed to modify cognitive expectancies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Assessed common expectancies concerning the effects of alcohol by eliciting expectancy dimensions from 20 undergraduates in a pilot study and then having 253 undergraduates rate the effects they expected from drinking alcohol along these dimensions. Results show that Ss expected moderate drinking (Phase 1) to result in relatively greater stimulation/perceived dominance and pleasurable disinhibition, whereas for heavy drinking they expected a greater degree of behavioral impairment. Stimulation/perceived dominance and pleasurable disinhibition were linearly related to drinking habits for Phase 1 drinking, with heavier drinkers expecting greater stimulation and pleasure. Results suggest that expectancies are important in understanding drinking patterns as well as behavior in drinking situations.

Pregaming is the practice of consuming alcohol prior to going out to a social event. Although pregaming has begun to receive research attention in the college setting, very little is known about this risky drinking behavior in high school students. As pregaming has health implications for both students who are college bound and those who are not, we examined the prevalence of this behavior in a sample of high school students who reported current alcohol use and completed pregaming measures (n = 233). The present study examined the associations of gender, age, alcohol expectancies, motivations for drinking (e.g., social, enhancement, and coping), and engagement in other risky drinking practices (i.e., general hazardous use and drinking game participation) with pregaming. Results indicate that pregaming was significantly associated with being older, being a male, having high levels of hazardous alcohol use, and participating in drinking games frequently. Pregaming also occurred most often before parties and sporting events and it was associated positively with frequency of attendance at parties where alcohol is available, the tendency to use alcohol at these parties, and the amount of alcohol consumed at these parties. We discuss the findings in the context of pregaming research that has been conducted with college students, and make suggestions regarding prevention and intervention efforts focused on this risky drinking practice.

The authors propose that trait urgency (the tendency to act rashly when distressed) is a risk factor for both alcohol abuse and bulimic symptoms, that disorder-specific expectancies influence whether one engages in one behavior or the other, and that expectancies moderate urgency's influence on those behaviors. Cross-sectional findings were consistent with the model. Problems from alcohol use were comorbid with binge eating and purging. Trait urgency was associated with both behaviors. Alcohol expectancies were associated with drinking levels and with problem drinking, but not with eating. Eating expectancies were associated with binge eating, but not with alcohol use or problems. Urgency's effect on binge eating was moderated by expectancies, but its effect on alcohol use and problem drinking was not. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

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.

This study compared the alcohol expectancies of 211 (62 men, 149 women) native Puerto Rican and 167 (54 men, 113 women) U.S. college students. Respondents completed a back-translated alcohol expectancy questionnaire. Results were factor analyzed separately by ethnicity. Comparison of factor structures indicated similarities and differences in expectancy structures. Puerto Rican respondents showed a tendency to associate positive aspects of alcohol effects with an expectancy for increased sociability, whereas for U.S. respondents these dimensions appeared to be independent. Puerto Ricans also had expectations of concurrent positive and negative alcohol effects on sexual behavior. A strong relationship between alcohol expectancies and alcohol consumption patterns was observed in both samples. Positive expectancies were better predictors of drinking than negative expectancies.

The present study investigated whether tension reduction expectancies were uniquely associated with self-reported mood following in-lab alcohol administration, given that little research has addressed this association. We also tested whether level of experience with alcohol, which may influence the learning of expectancies, moderated expectancy-mood associations. Regularly drinking college students (N = 145) recruited through advertisements completed self-report measures of positive alcohol expectancies, alcohol involvement, demographics, and pre- and post-drinking mood, and then consumed alcohol ad libitum up to four drinks in the laboratory. Regression analyses controlling for pre-consumption mood, blood alcohol concentration, and all other positive expectancies showed tension reduction expectancies to be a marginally significant positive predictor of negative mood post-drinking. This association was significant only for those who achieved lower blood alcohol concentrations in lab and those who reported less involvement with alcohol (i.e., lower typical quantity, heavy episodic drinking frequency, and years of regular drinking). Findings suggest that associations between expectations for mood and actual post-drinking mood outcomes may operate differently for less versus more involved drinkers. Clinical implications pertain to early intervention, when expectancies may be less ingrained and perhaps more readily modified. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

There is little question that alcohol plays a role in social situations. Most of the research in this area has used a paradigm designed to understand the effects of consuming alcohol on anxiety and social behavior. Most of the previous studies have looked only at situational factors-with limited focus on personality variables, using confederates to control the social reaction that participants received, with drinking generally occurring in a solitary situation. In the present study we were interested in understanding the interpersonal nature of reactions to alcohol consumption. The focus of this study was on the stimulus value of alcohol rather than anticipated or pharmacological effects of alcohol consumption. In large groups, individuals completed cognitive-personality measures assessing typical alcohol consumption, alcohol expectancies, and social anxiety. In the second part of the study, participants were paired with a member of the opposite sex with whom they had no previous contact: perceptions of their partner and metaperceptions were assessed after 4 and 15 minutes (before and after choosing a beverage--beer, soft drinks, etc.). Results indicate that positive alcohol expectancies interact with partner alcohol selection in predicting changes in metaperceptions of friendliness and relaxation. With friendliness, this result was most pronounced in men. These results are discussed in terms of the role alcohol expectancies may play in filtering alcohol relevant environmental information, and the influence of positive alcohol expectancies in mixed-sex drinking situations.  相似文献

There is a well-established relationship between alcohol expectancies and drinking behavior. The purpose of the present study was to extend the literature by examining the role of alcohol expectancies in determining readiness to change drinking behavior among injured emergency department patients who screened positive for hazardous drinking. Negative expectancies were found to partially mediate the relationships of alcohol-related injuries and injury aversiveness to readiness to change drinking behavior. Results suggest that negative alcohol expectancies are a potential means of increasing patients' readiness to change drinking behavior.

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.

Alcohol expectancies have been statistically modeled as memory networks that influence future consumption. To test the organization of expectancies suggested by these models, a modified Stroop color-naming task incorporated expectancy words associated in past research with heavy and light drinking. Light and heavy drinkers ink-named expectancy targets after being cued with an alcohol beverage word or a nonalcohol beverage word. Consistent with predictions derived from statistical models, heavy drinkers displayed significant interference when arousing expectancy words had been primed by an alcohol beverage word, whereas light drinkers displayed significant interference when sedating expectancy targets had been so primed. These results reinforce the idea that mediation of alcohol use by expectancies may be implicit as well as explicit. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
