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.

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.

Using an in vivo manipulation, this study examined whether alcohol outcome expectancies (AOEs) vary across environmental settings. Two hundred twenty-one undergraduates were randomly assigned to 1 of 4 conditions in which environmental context (an on-campus bar vs. a laboratory) and instructed phase of intoxication ("just enough to begin to feel intoxicated" vs. "too much to drink") were manipulated. AOEs were assessed with a revised version of the Effects of Alcohol Scale (L. Southwick, C. Steele, A. Marlatt, & M. Lindell, 1981). Compared with participants tested in the laboratory, individuals exposed to the on-campus bar expected greater alcohol-related stimulation/perceived dominance and pleasurable disinhibition. Women expected more behavioral impairment during the latter stage of intoxication. These findings highlight the importance of ecologically valid research in this area, as well as cue-exposure assessment and treatment approaches.

Assessed the ability of the theory of planned behavior (TPB) to account for drivers' intentions to commit 4 specific driving violations: drinking and driving, speeding, close following, and overtaking in risky circumstances. A stratified sample of drivers (N?=?881) was surveyed with a questionnaire constructed to measure attitudes toward behaviors, subjective norms, perceived behavioral control, and behavioral intentions, the key constructs in TPB. Results showed that the addition of perceived behavioral control led to significant increments in the amount of explained variance in intentions, thereby supporting the theory. The relation between subjective norms and behavioral intentions was consistently stronger than that between attitudes toward behaviors and behavioral intentions. Analyses of variance (ANOVAs) differentiated demographic subgroups of drivers in terms of behavioral beliefs, outcome evaluations, normative beliefs, motivation to comply, and control beliefs.

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.

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.

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.

A laboratory experiment and 2 field studies tested the hypothesis that alcohol affects attitudes and intentions toward drinking and driving. Sober and intoxicated participants completed a questionnaire assessing their attitudes and intentions to drink and drive in a number of situations. Results indicated that when asked general or noncontingent questions, sober and intoxicated participants were equally negative about this behavior. However, when a contingency was embedded in the question (e.g., "would you drink and drive only a short distance?"), intoxicated participants were significantly less negative about drinking and driving. These results are consistent with alcohol myopia (C. M. Steele & R. A. Josephs, 1990)—the notion that alcohol intoxication decreases cognitive capacity so that people are more likely to attend to only the most salient cues.

This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge, behavioral skills, or condom use. Results indicated that across the sample of studies, communications taught recipients about facts related to HIV and also induced favorable attitudes and expectancies, greater control perceptions, and stronger intentions to use condoms in the future. Moreover, messages that presented attitudinal information and modeled behavioral skills led to increased condom use. Results are discussed in the context of theories of human behavior and change and in reference to HIV-prevention interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

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

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.

This study experimentally tested the effects of a drinking event on HIV-related behavioral skills and condom attitudes. Sixty unmarried, heterosexual men were assigned to 1 of 3 conditions (sober, placebo, or alcohol). Participants who consumed alcohol demonstrated lower skill to negotiate for condom use relative to sober controls. More negative condom attitudes were expressed by participants with stronger sex-related alcohol expectancies, especially when these expectancies were triggered by subjective intoxication. Hierarchical regression analyses revealed that the experimental factors accounted for variance in behavioral skills and condom attitudes beyond that explained by known predictors of sexual risk.

288 adults and 265 university students responded to a questionnaire concerning beliefs about the effects of alcohol, which included a measure of evaluation of alcohol effects. Analyses were performed with measures of frequency of drinking episodes, usual quantity consumed/episode, frequency of intoxication and consumption of 8 or more drinks at one sitting, and estimated number of drinks per year. Evaluation of the undesirable consequences of drinking added significantly to the prediction of quantity-based drinking variables. It is suggested that perceived desirability of alcohol effects is an important factor in understanding the relationship of expectancies to drinking.

The authors tested a restraint-based model that binge drinking is a function of being tempted to drink alcohol while also being concerned about avoiding excessive alcohol intake. Underage (18-to 20-year-olds, 204 men and 225 women) college student drinkers completed measures that assessed the attraction to alcohol (e.g., temptation to drink, alcohol expectancies), concern about regulating alcohol intake (e.g., restriction of alcohol intake, reasons for limiting drinking), and alcohol-related outcomes (binge drinking, alcohol problems). In separate hierarchical multiple regressions, the attraction to alcohol accounted for significant amounts of additional variance in each of the alcohol outcomes. Concern about regulating alcohol intake accounted for additional variance, above that explained by attraction to alcohol. The results suggest that interventions for underage binge drinking should include training in the skills for regulating alcohol intake.

AIMS: The chief purpose of the current study was to assess whether young children endorse expectancies specific to alcohol. DESIGN: In order to accomplish this aim, a 2 (gender of child) by 2 (gender of adult drinker) by 2 (grade level) by 2 (beverage type) repeated measure design was employed with beverage type as the repeated measure. SETTING: Data were collected within elementary schools located in two Midwestern states. PARTICIPANTS: One hundred and twenty-four second and third graders (42% male) participated in individually structured interviews. MEASUREMENTS: The expectancy interview was based on the Children's Alcohol-Related Expectancy Questionnaire and assessed each child's beliefs about the desirable and undesirable consequences which adult men and women might experience after drinking alcohol (beer) and a control beverage (iced tea). FINDINGS: The results indicated that children endorsed significantly more undesirable expectancies for beer than for iced tea, and more desirable expectancies for iced tea than for beer. In addition, children's expectancies varied as a function of the gender of the drinker. Specifically, both second- and third-graders expected more undesirable outcomes for women than for men, and second graders expected fewer desirable outcomes for women than for men, regardless of beverage. CONCLUSIONS: Prior to substantial experience with alcohol consumption, children have already developed expectancies for alcohol. Specifically, young elementary children endorse predominantly undesirable expectancies for beer.  相似文献

Among a sample of 180 male and 226 female undergraduates, 84.2% reported a heavy drinking episode (5+ drinks for men, 4+ for women) within the previous 90 days. Principal-components analysis revealed 3 alcohol-related problem factors among the heavy drinkers (Careless Behavior, Risky/Reckless Behavior, and Authority Problems). Nearly all heavy drinkers experienced a careless behavior that was due to drinking (92.7%), and many reported a risky/reckless behavior (60.2%), yet only one third (33.9%) experienced an authority problem. Guttman scaling procedures revealed a progression from Careless Behavior to Reckless/Risky Behavior to an Authority Problem. Heavy drinkers with an authority problem drank more frequently, consumed more when drinking, endorsed more alcohol expectancies, and reported earlier ages of initial and regular drinking than other groups.

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)  相似文献

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.

Gambling is an important public health concern. To better understand gambling behavior, we conducted a classroom-based survey that assessed the role of the theory of planned behavior (TPB; i.e., intentions, subjective norms, perceived behavioral control, and attitudes) in past-year gambling and gambling frequency among college students. Results from this research support the utility of the TPB to explain gambling behavior in this population. Specifically, in TPB models to predict gambling behavior, friend and family subjective norms and perceived behavioral control predicted past-year gambling, and friend and family subjective norms, attitudes, and perceived behavioral control predicted gambling frequency. Intention to gamble mediated these relationships. These findings suggest that college-based responsible gambling efforts should consider targeting misperceptions of approval regarding gambling behavior (i.e., subjective norms), personal approval of gambling behavior (i.e., attitudes), and perceived behavioral control to better manage gambling behavior in various situations.
