青少年饮酒期望与饮酒行为的关系:追踪研究的证据

通过对1000余名青少年为期一年的追踪调查,探讨了青少年饮酒期望与饮酒行为之间的关系,同时考察了饮酒期望的发展和性别差异。研究结果表明:(1)一年来青少年的饮酒行为、饮酒消极期望和饮酒积极期望都显著增加;女生的饮酒行为和饮酒积极期望的增加都显著高于男生。(2)第二次测查时,青少年的饮酒行为、饮酒积极期望和饮酒消极期望高于一年前原同年级的学生。(3)饮酒积极期望、消极期望和饮酒行为之间的基本关系一年来没有发生变化:消极期望可能降低饮酒行为,积极期望可能增加饮酒行为,消极期望对积极期望与饮酒行为的关系具有显著的调节作用。但是消极期望对饮酒行为的作用降低,积极期望的作用升高。     

Predicting Undergraduate Condom Use with the Fishbein and Ajzen and the Triandis Attitude-Behavior Models: Implications for Public Health Interventions1

The present study used two social-psychological theories of attitude-behavior relationships to investigate condom use by college undergraduates. One purpose of the present research is to provide information for public health practitioners to better design theory-based interventions to reduce the incidence of STD's by increasing the use of condoms. Another purpose is to compare the relative usefulness of two attitude-behavior models in predicting condom use. The Fishbein and Ajzen theory of reasoned action (Ajzen, 1988; Fishbein & Ajzen. 1980) was compared with a version of Triandis' theory of attitude-behavior relations (Triandis, 1977). Of major interest was whether variables in this version of the Triandis model increased the explanatory power of the Fishbein and Ajzen model in the prediction of condom use intention and behavior. In addition, specific outcome beliefs and normative beliefs held by subjects were used to predict condom use. One hundred and ninety college undergraduates were given a questionnaire designed to measure the components of the two models. Three months after completing the questionnaire, subjects were contacted by phone to record the subject's frequency of condom use (if the subject reported having had intercourse) during the 3-month period between initial assessment and follow-up. In the prediction of intention to use a condom, results indicate that one variable from the Triandis model, personal normative beliefs, increases the explanatory power offered by the expectancy value and normative belief components of the Fishbein and Ajzen model. In the prediction of reported condom use during the 3-month follow-up period, two variables from the Triandis model—perceived susceptibility and AIDS fear—significantly increased the predictive power of the Fishbein and Ajzen model. Based on these results, the authors propose an alternative model to explain undergraduate condom use. The implications of these findings for public health interventions to encourage the use of condoms is discussed.     

Alcohol expectancies and context-specific drinking behaviors among female college athletes

Alcohol expectancies have been associated with drinking behaviors among college students. Few studies, however, have focused on researcher-labeled "positive" and "negative" expectancies as well as the valuations (i.e., desirability) of these expectancies. Moreover, research on the correlates of heavy drinking among female college athletes remain relatively sparse, despite the prevalence of elevated alcohol use in this population. We examined the associations of expectancies and valuations with frequency of heavy drinking and context-specific drinking behaviors. The sample consisted of 145 female college athletes (mean age=19.6; range=17 to 22) who completed self-report surveys and indicated alcohol use in the past 30 days. Regression analyses indicated that favorable valuations of negative expectancies were related to heavy drinking, and that valuations accounted for significant proportions of variance in the model. Elevated endorsement of negative expectancies was also associated with the perceived likelihood of heavy use in convivial and personal-social drinking contexts, and favorable valuations of these expectancies accounted for significant variance in these models. These findings highlight the relevance of negative expectancies and valuations with respect to heavy drinking and context-specific drinking behaviors among female college athletes. The perception of "negative" effects of alcohol as "positive" could help explain the high rates of problematic drinking among female athletes. Future research considerations and potential implications for assessment and prevention efforts are discussed.     

The influence of alcohol expectancy priming and mood manipulation on subsequent alcohol consumption

Studies showing that verbal priming can implicitly affect alcohol consumption have been used to support cognitive models of expectancies. However, because expectancy words reflect affective states as well as drinking outcomes, mediation through an affective pathway remains theoretically plausible (i.e., such words inadvertently may affect mood, which in turn influences drinking). The primary pathway was identified (and expectancy theory was tested) by comparing memory priming (using alcohol expectancy or neutral words) with mood induction (using positive or neutral music); an unrelated experiment paradigm allowed the priming manipulation to implicitly affect drinking. Men in the alcohol priming group drank significantly more than men in each of the other conditions, and, consistent with theory, men with histories of heavier drinking drank the most when primed with alcohol expectancies, indicating that expectancies can function as automatic memory processes.     

When the party for some becomes a problem for others: the effect of perceived secondhand consequences of drinking behavior on drinking norms

The authors examined the influence of fraternity men's expectancies regarding secondhand consequences of excessive drinking behavior on normative standards regarding alcohol use and consumption levels. Participants were 381 men from 26 chapters of 2 national fraternities. One organization participated in a brief intervention involving discussion of secondhand consequences of excessive drinking. Immediate influence of the intervention on perceived secondhand consequences of alcohol use was assessed using a posttest-only, randomized groups design. Results supported a hypothesized measurement model with 1 overall secondhand consequence expectancy construct and 4 subfactors: (a) Noise Disruptive of Sleep and Study, (b) Violence, (c) Sexual Assault, and (d) Property Damage. Cross-sectional analysis at the chapter and individual levels demonstrated that secondhand expectancies had an indirect effect on alcohol consumption, mediated by personal consumption standards for limiting alcohol consumption. The intervention had an effect on secondhand expectancies. Findings suggest that interventions with intact groups can increase secondhand expectancies regarding excessive drinking and may lead to a reduction in excessive alcohol consumption.     

Counselling of alcohol-dependents based on a model of change to abstinence

A model of change to abstinence in alcohol-dependents is presented based on the theory of reasoned action of Ajzen & Fishbein. The model includes attitudes, defence mechanisms and norms about aspects of alcohol consumption. An empirical study supports elements of the model. Conclusions pertinent to the counselling process are drawn.     

Comorbid interpretation and expectancy bias in social anxiety and alcohol use

Background: In two studies, the present research examined whether being high in both social anxiety and alcohol use disorder symptoms is associated with a comorbid interpretation and expectancy bias that reflects their bidirectional relationship.

Design: Cross-sectional, quantitative surveys.

Methods: Measures of social anxiety and alcohol use disorder symptoms, as well as an interpretation and expectancy bias task assessing biases for social anxiety, drinking, and comorbid social anxiety and drinking.

Results: In Study 1 (N?=?447), individuals high (vs. low) in social anxiety had stronger social threat bias and individuals high (vs. low) in alcohol use disorder symptoms had stronger drinking bias. Those high in both social anxiety and alcohol use disorder symptoms endorsed interpretations and expectancies linking social interaction with alcohol use. Comorbid bias predicted membership into the high social anxiety/drinking group, even after taking into account single-disorder biases. In Study 2 (N?=?325), alcohol use disorder symptoms predicted drinking bias and social anxiety symptoms predicted social anxiety bias. Alcohol use disorder symptoms, social anxiety symptoms, and their interaction predicted comorbid interpretation and expectancy bias.

Conclusion: Results indicate unique cognitive vulnerability markers for persons with comorbid social anxiety and alcohol use disorder symptoms, which may improve detection and treatment of this serious comorbidity.     

Efficacy of expectancy challenge interventions to reduce college student drinking: A meta-analytic review

Interventions challenging alcohol expectancies may lead to reductions in alcohol consumption. We conducted a meta-analysis to examine the efficacy of alcohol expectancy challenge (EC) interventions for college alcohol abuse prevention. Included were 14 studies (19 EC interventions) that measured alcohol expectancies and consumption, provided sufficient information to calculate effect sizes, and were available as of June 2010 (N = 1,415; M age = 20 years; 40% women; 88% White). Independent raters coded participant characteristics, design and methodological features, and intervention content, and calculated weighted mean effect sizes at first follow-up, using both fixed and random effects models. Compared with controls, EC participants reported lower positive alcohol expectancies, reduced their alcohol use, and reduced their frequency of heavy drinking (d+s ranged from 0.23 to 0.28). Within-group improvements in alcohol expectancies and consumption emerged for the EC group only; relative to their own baseline, EC participants reported lower positive alcohol expectancies, reduced their alcohol use, and reduced their frequency of heavy drinking (d+s ranged from 0.13 to 0.36). Supplemental analyses found improvements in specific alcohol expectancies (social, sexual, tension, and arousal) both between groups and within group. The short-term effects of EC interventions on college student drinking are not maintained at follow-ups greater than 4 weeks. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Lasting effects of alcohol: Subliminal alcohol cues,impairment expectancies,and math performance

Many people believe that drinking alcohol reduces cognitive performance, and prior research has shown such expectancy‐related impairment even when people merely thought that the (non‐alcoholic) drink they consumed contained alcohol. This study tested whether subliminal priming with alcohol‐related cues would similarly result in expectancy‐consistent cognitive performance decrements. Additionally, the moderating role of alcohol use was examined. After assessing participants' baseline math performance, participants were primed with alcohol‐related or neutral words and then completed a post‐treatment math task. Whereas impairment expectancies had no influence on math performance in control participants, expectancies predicted math performance for participants primed with alcohol‐related words. As hypothesized, expectancy‐consistent impairment in performance was only observed among high alcohol users. The current findings suggest that, in the presence of alcohol‐related cues in the environment, some people may perform less on cognitive tasks even in the absence of actual or assumed alcohol consumption and without being aware of it.

Further examination of the psychometric properties of the comprehensive effects of alcohol questionnaire

Although the expectancies component of the Comprehensive Effects of Alcohol Questionnaire has previously been shown to be factorially valid, the factor structure of its valuations component has not previously been examined. The aims of this paper were: (i) to replicate the factor structure of the expectancies items; (ii) to explore the factor structure of the valuations items; and (iii) to investigate the utility of using the Comprehensive Effects of Alcohol Questionnaire to predict drinking behavior. The questionnaire was administered to 1004 university students along with measures of quantity and frequency of alcohol consumption. Fromme, Stroot, and Kaplan's (1993) factor structure of the expectancies scales was replicated. The factor structures of the negative valuations scales were characterized by 2 rather than 3 factors. Negative expectancies improved upon the prediction of drinking quantity and frequency over-and-above positive expectancies, and valuations further improved prediction over-and-above expectancies. Theoretical and clinical implications are discussed.     

Perceived Norms,Outcome Expectancies,and Collegiate Drinking: Examining the Mediating Role of Drinking Motives

The authors examined the mediational role of drinking motives in explaining the associations among psychosocial antecedents and collegiate drinking. Results indicated that drinking motives partially mediated the relationships between outcome expectancies, perceived norms, alcohol use intensity, and alcohol‐related negative consequences.     

Mediators in the Relationship Between Parental and Peer Characteristics and Beer Drinking by Early Adolescents1

Social learning theory suggests that parents and peers influence adolescent drinking directly by providing social reinforcement and models for imitation, and indirectly by first influencing various expectations adolescents form about drinking. In this study, longitudinal data were used to investigate several mediators that could account for the relationships between adolescent beer drinking and parent and peer drinking behaviors and attitudes. The results show that peer drinking indirectly influences adolescent drinking by shaping adolescents' norms on drinking, drinking preferences, and expected consequences of drinking related to friends and problem behavior, whereas parental alcohol use and peer attitude toward alcohol largely directly influence adolescent beer drinking. The results suggest that influence is in large part direct or indirect depending on the source of the influence. In addition, different types of mediators may account for different relationships.     

Cross-Sex Best Friendship Influences on Early Adolescent Cigarette and Alcohol Expectancies and Use

In this study, the author investigates the influences of cross-sex best friends in early adolescence in regard to cigarettes and alcohol. Specific goals include determining the prevalence of cross-sex best friendships, investigating expectancies and perceived approval of the use of cigarettes and alcohol, and examining substance use levels. A group of urban sixth, seventh, and eighth graders completed a survey that addressed these issues. Results indicate the presence of cross-sex best friendships in the sample. Significant findings on cross-sex best friends' influence include positive expectancies for alcohol in sixth (p = .006) grade, the perception of seventh graders that the best friend's attitudes about smoking (p = .003) and drinking (p = .001) are less negative, and higher levels of cigarette use in sixth (p = .001) and eighth (p = .024) grade and alcohol use in sixth (p = .008), seventh (p = .002), and eighth grades (p = .039).     

The relationship between viewing US-produced television programs and intentions to drink alcohol among a group of Norwegian adolescents

The aim of this study was to examine the influence of exposure to US-produced television programs and family rules prohibiting alcohol use on the development of normative beliefs, expectancies, and intentions to drink alcohol in the next 12 months among a group of Norwegian adolescents who reported that they had not previously consumed alcohol. Data were collected via a survey administered to 622 eighth and ninth graders enrolled at ten junior highs in southeastern Norway. To examine these relationships we tested the fit of a structural equation model which was based on the Theory of Planned Behavior (Ajzen, 1988). Data from the non-drinkers (n= 392, 63% of the respondents) were used. To control for the influence of peer drinking on behavioral intentions, our model was tested under two group conditions: (1) those subjects reporting that they have no friends who drink alcohol and (2) those subjects reporting that they have one or more friends who drink. The findings indicate that the influence of TV exposure was a significant predictor (directly) of normative beliefs, expectancies (indirectly) and intentions to drink (both directly and indirectly) only for those subjects who reported having no friends who drink. For the group with non-drinking friends, family rules constrain intentions only indirectly by influencing normative beliefs. For those with friends who drink, however, family rules have a direct (inverse) effect on intentions. It is concluded that exposure to US-produced television programs functions as a limited knowledge source only for those subjects who had little or no personal experience with alcohol while the presence of family rules have limited impact on behavioral intentions.     

The Role of Beliefs in Mother-Adolescent Conflict: An Application of the Theory of Planned Behavior

This mixed method study applies components of the theory of planned behavior (Ajzen and Fishbein 1980) to mother-adolescent conflict. We examine if three kinds of beliefs—behavioral, control, and normative—predict patterns of family conflict. Forty mother-adolescent dyads completed an open-ended interview, self-report measures of conflict, and an observational measure of family interaction. Hierarchical multiple regressions revealed that mothers’ and adolescents’ beliefs about the costs and benefits of conflict significantly predicted how they interacted and perceived conflict within dyads. Sex differences and differences between mothers and adolescents were identified. This work contributes to our understanding of the role of both general and specific beliefs in family conflict.     

Evaluation of a single-session expectancy challenge intervention to reduce alcohol use among college students

In this study, the authors developed and evaluated a single-session experiential expectancy challenge (EC) intervention, seeking to reduce alcohol use by changing key positive expectancies among moderate to heavy drinking male and female college students. Participants (N=217) were randomly assigned to attend a 90- to 120-min EC session, CD-ROM alcohol education, or assessment only. Participants were assessed at pretest, posttest, and 1-month follow-up. Exposure to the EC intervention led to significant decreases in alcohol expectancies and subsequent alcohol consumption in both genders at follow-up. No significant changes were evident in either control condition. This study is the first to effectively decrease expectancies and drinking in college students with a single-session EC intervention. Further, although several studies have demonstrated the utility of the intervention with men, it is the first to do so with women. This study represents a critical step in the process of translating an innovative, theory-based intervention into a more practical format that makes it more accessible to those who seek effective drinking-reduction strategies for college campuses.     

Children's alcohol cognitions prior to drinking onset: discrepant patterns from implicit and explicit measures

Prior to drinking onset, children report stronger negative versus positive beliefs on self-report alcohol expectancy questionnaires, with some attenuation of this negativity as they transition into adolescence. Traditional alcohol expectancy assessments, however, capture endorsement of deliberative propositions about drinking outcomes. Measurement of implicit alcohol associations may elucidate automatic evaluations, clarifying the role of nondeliberative cognition in the initiation of alcohol use among youth. Few studies have assessed implicit alcohol cognition among children and younger adolescents, with inconsistent findings regarding the nature of these automatic associations within and between age groups. Eighty-nine 3rd and 4th graders and 91 7th and 8th graders completed an alcohol expectancy measure and two unipolar alcohol Implicit Association Tests (IAT) measuring positive and negative alcohol associations independently. On the explicit measure older compared with younger participants rated positive drinking outcomes as more likely and negative outcomes as less likely. Older compared with younger students were also more neutral/moderate in their evaluations of positive drinking outcomes. On the IATs, scores for the full sample indicated negative alcohol associations, and Negative IAT scores were higher for older compared with younger participants. However, the valence of implicit alcohol associations was qualified by the order of explicit versus implicit assessment; for those who completed the IATs prior to the explicit expectancy measure, alcohol associations were positive. Findings replicate and extend prior research conducted with preonset youth. Implications regarding the role of automatic and controlled processes in drinking onset and directions for future work on children's alcohol cognition are discussed.
