Evaluations and expectancies of alcohol and marijuana problems among college students.

Two studies examined the associations between evaluations (good-bad) and expected likelihood (likely-unlikely) of alcohol- and marijuana-related problems and hazardous consumption and problems among college students. Participants provided data on alcohol use, alcohol-related problems, and expectancies and evaluations of alcohol problems; marijuana use indices, marijuana-related problems, marijuana effect expectancies, and likelihood and evaluations of marijuana problems. Evaluations of alcohol problems were positively related to the number of binge drinking occasions and alcohol-related problems. The interaction between evaluations and expectancies was significant in predicting the number of binge drinking occasions. Expectancies demonstrated a curvilinear relationship with binge drinking and alcohol-related problems. Marijuana users evaluated marijuana-related problems as less negative and less likely to occur than did nonusers. Expectancies, but not evaluations, of negative consequences were significantly associated with marijuana use intensity. Expectancies of problems demonstrated a curvilinear relationship with marijuana-use intensity and marijuana problems. Men evaluated alcohol and marijuana problems less negatively than did women. In summary, the expected likelihood of alcohol-marijuana problems and the evaluation of such problems represent a vulnerability factor associated with increased liability for hazardous alcohol and marijuana use.     

Alcohol-aggression expectancies and dispositional rumination moderate the effect of alcohol consumption on alcohol-related aggression and hostility

Alcohol consumption increases aggression, but only in some drinkers. This study extends previous work to show how expectancies for alcohol-induced aggression and dispositional rumination moderate the link between alcohol consumption and alcohol-related aggression and hostility in a sample of 285 men and women. Alcohol-aggression expectancies and quantity of alcohol interacted to predict alcohol-related hostility and aggression. Trait rumination moderated the effect of alcohol consumption on aggressive acts. Finally, women who ruminated were more likely to report alcohol-related aggression than were men who ruminated. These results suggest that alcohol expectancies for aggression and rumination constitute two important cognitive facilitators of alcohol-related aggression and hostility, and that gender plays an important role in these relations.     

Alcohol-specific parenting,adolescent alcohol use and the mediating effect of adolescent alcohol-related cognitions

Objectives : Previous research indicated that alcohol-specific parenting is an important precursor of adolescent alcohol use, but failed to define the underlying mechanism. Based on social cognitive theory, alcohol-related cognitions such as alcohol refusal self-efficacy and alcohol-related expectancies were hypothesised to mediate this link.

Design : A cross-sectional survey included 1349 mothers and their sixth grade (11–12?years old) adolescent offspring. Structural equation modelling was employed to test the association between alcohol-specific parenting and adolescent alcohol use, mediated by adolescent alcohol-related cognitions.

Main outcome measures : Adolescent alcohol use, drinking refusal self-efficacy and alcohol expectancies.

Results : The associations between frequency of communication, maternal alcohol use and adolescent alcohol use were mediated by negative alcohol-related expectancies. The associations between quality of communication, rules and disclosure and adolescent alcohol use were mediated by self-efficacy.

Conclusions : The present study provides a first indication that the underlying mechanism of the association between the most important alcohol-specific parenting practices and adolescent alcohol use can be contributed to the mediating effect of alcohol-refusal self-efficacy.     

Protective behavioral strategies as a mediator and moderator of the relationship between self-regulation and alcohol-related consequences in first-year college students

This study examined protective behavioral strategies (PBS) as a potential mediator and moderator of the relationship between self-regulation and alcohol-related consequences. Participants were 249 first-year undergraduate men and women. The use of PBS partially mediated the relationship between self-regulation and alcohol-related problems (i.e., supporting the "self-control equals drinking control" hypothesis). However, use of PBS appeared more important for those with poorer self-regulation abilities (supporting the "PBS protect the impaired" hypothesis). Because both mediation and moderation were supported, a moderated mediation model was tested. The moderated mediation model demonstrated that the negative relationship between self-regulation and alcohol-related consequences could be explained by use of PBS for individuals with poor-to-average self-regulation but not for individuals with above-average, self-regulation abilities. Implications of the study's findings are discussed.     

Understanding the Relationship Between Religiousness, Spirituality, and Underage Drinking: The Role of Positive Alcohol Expectancies

Research has consistently found that religiousness and spirituality are negatively associated with underage drinking. However, there is a paucity of research exploring the mechanisms by which these variables influence this important outcome. With 344 underage young adults (ages 18–20; 61 % women), we investigated positive alcohol expectancies as a mediator between religiousness and spirituality (measured separately) and underage alcohol use. Participants completed the Religious Commitment Inventory-10, Daily Spiritual Experiences Scale, Alcohol Expectancies Questionnaire, and Drinking Styles Questionnaire. Results indicate less positive alcohol expectancies partially mediate the relationship between both religiousness and spirituality and underage alcohol use. This suggests religiousness and spirituality’s protective influence on underage drinking is partly due to their influence on expectations about alcohol’s positive effects. Since underage drinking predicts problem drinking later in life and places one at risk for serious physical and mental health problems, it is important to identify specific points of intervention, including expectations about alcohol that rise from religious and spiritual factors.     

Alcohol expectancies, alcohol use, and hostility as longitudinal predictors of alcohol-related aggression

The direct and interactive effects of alcohol expectancies for aggression, dispositional hostility, and heavy alcohol consumption on alcohol-related physical aggression were examined across the first four years of marriage in a sample of 634 newlywed couples. For husbands, alcohol aggression expectancies predicted increases in alcohol-related aggression; across husbands and wives, however, aggression expectancies were not found to interact with hostility or alcohol consumption to predict physical aggression. Consistent with previous research, hostility and alcohol consumption interacted with each other to predict alcohol-related aggression. Specifically, for both husbands and wives high in dispositional hostility, heavy alcohol consumption was positively associated with the occurrence of alcohol-related aggression; for those low in dispositional hostility, however, there was no association between alcohol consumption and alcohol-related aggression. Findings are contrasted with previous longitudinal research on alcohol aggression expectancies and physical aggression in married couples. The article discusses the extent to which findings may vary depending on whether expectancies are assessed in relation to alcohol's effect on one's own behavior versus alcohol's effect on others' behavior.     

An Empirical Analysis of Fraternity and Sorority Individual-Environmental Interactions With Alcohol

Hierarchical linear modeling was used to analyze fraternity and sorority individual-environmental interactions for 3,756 Greek undergraduate students at a large public university. Alcohol expectancies were measured with items used to assess the degree to which people believe alcohol has positive effects. For sorority students, expectancies were negatively related to chapter culture emphasizing service and civic responsibility. Expectancies were positively associated with chapter culture emphasizing glorification of alcohol use in both fraternity and sorority chapters. Among sorority students, consumption was predicted by group-level service orientation, holding expectancies constant. The strength of the relationship between alcohol expectancies and consumption level increased among fraternity and sorority members, according to chapters' progressive exaltation of the role of alcohol. The implications of the findings are discussed for observed gender differences, the role of self-selection into these unique student organizations, and current efforts to recalibrate Greek chapters toward greater personal safety and control.     

The effects of familial risk, personality, and expectancies on alcohol use and abuse

This study tested a structural model of the association between familial risk, personality risk, alcohol expectancies, and alcohol abuse in a sample of 224 young adult offspring of alcoholics and 209 offspring of nonalcoholics. The results provided support for 2 personality-risk pathways, a social deviance proneness and an excitement/pleasure seeking path, that accounted for a significant portion of the association between a familial alcoholism and alcohol abuse. The path from familial alcoholism to social deviance proneness lead directly to alcohol problems. The path from familial alcoholism to excitement/pleasure seeking was associated with increased drinking, which, in turn, was associated with alcohol problems. Positive alcohol expectancies accounted for part of the association between excitement seeking and alcohol use. The results suggest 2 different biopsychosocial mechanisms that elevate risk for abuse in the offspring of alcoholics.     

NEO PI-R predictors of alcohol use and alcohol-related problems

We investigated the relationships between Five-factor model domains and facets and drinking and alcohol-related problems. We also examined the moderating effects of gender. Two hundred students (99 men and 101 women) who had used alcohol in the past year completed self-report and interview assessments. Bivariate analyses demonstrated some significant relationships. In the multivariate analyses that controlled for gender, Neuroticism and Conscientiousness were linked to drinking, but only some of the facets from these domains had significant relationships to drinking. Facets of Extraversion and Agreeableness, but not these domains, were associated with drinking. Neuroticism and Conscientiousness and most of their facets were related to alcohol-related problems in the multivariate analyses. The interactions between gender and traits were not significant.     

Using a modified Stroop task to implicitly discern the cognitive organization of alcohol expectancies

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 o falcohol use by expectancies may be implicit as well as explicit.     

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.     

Impact of experimentally induced positive and anxious mood on alcohol expectancy strength in internally motivated drinkers

The effects of musically-induced positive and anxious mood on explicit alcohol-related cognitions (alcohol expectancy strength) in 47 undergraduate students who consume alcohol either to enhance positive mood states (for enhancement motives) or to cope with anxiety (for anxiety-related coping motives) were investigated. Pre- and post-mood induction, participants completed the emotional reward and emotional relief subscales of the Alcohol Craving Questionnaire - Now. The hypothesis that anxiety-related coping motivated drinkers in the anxious mood condition (but not those in the positive mood condition) would exhibit increases in strength of explicit emotional relief alcohol expectancies after the mood induction was supported. An additional, unanticipated finding was that enhancement-motivated drinkers in the anxious condition also showed significant increases in strength of explicit emotional relief (but not emotional reward) alcohol expectancies. The hypothesis that enhancement-motivated (but not anxiety-related coping motivated) participants would exhibit increases in explicit emotional reward expectancies following exposure to the positive mood induction procedure was not supported. Taken together with past research findings, the current results highlight the importance of distinguishing between subtypes of negative affect (i.e., anxious and depressed affect) in exploring the affective antecedents of explicit alcohol outcome expectancies.     

Prospective analysis of comorbidity: tobacco and alcohol use disorders

Alcohol use disorders (AUD) and tobacco use disorders (TD) frequently co-occur. The authors examined AUD-TD comorbidity over time using a state-trait (ST) model. The ST model represents variance in AUD/TD as a traitlike factor that spans measurement occasion and identifies distinct sources of variance in AUD-TD comorbidity. The ST model was evaluated on 450 young adults (baseline age = 18.5 years; 51% with family history of alcoholism) assessed 5 times over 7 years. The ST model demonstrated superior fit over a first-order autoregressive model. The tendency to diagnose with AUD and TD was partially explained by family history of alcoholism; this relationship was mediated by childhood stressors, alcohol expectancies, and behavioral undercontrol. Results supported a common third-variable influence (vs. directional) model of comorbidity. The ST model is an important conceptual and methodological approach to the prospective study of comorbidity in general.     

Self-construal and social anxiety: Considering personality

Self-construal has been identified as a potential means to explain cultural differences in social anxiety. Yet, research findings suggest that self-construal is an individual difference as much as a cultural difference. We tested for mediation and moderation regarding self-construal, social anxiety, and other primary individual difference constructs. Our results indicated that the relation of extraversion and neuroticism to social anxiety was partially mediated by independent self-construal. In addition, the relationship between social anxiety and interdependent self-construal was moderated by neuroticism. These results suggest that personality traits play an important role in the relationship between social anxiety and self-construal. Clinical interventions that consider the interplay between self-construal and personality may be helpful in decreasing social anxiety.     

A message in a bottle: Extrapharmacological effects of alcohol on aggression

The physiological and expectancy effects of alcohol consumption on the aggressive behavior of 116 general-population males aged 18-45 years were analyzed separately in a naturalistic field experiment using a 3 × 3 Balanced Placebo Design (BPD). Participants were given a non-alcoholic drink, a drink targeting a Blood Alcohol Concentration (BAC) of .05%, or a drink targeting a BAC of .1%. Within these three groups, three expectancy levels were induced regarding the quantity of alcohol ingested. Aggressive behavior was measured as retaliation against an aggressive confederate, in the form of amounts of hot sauce and salt administered in a taste test. Expectancies significantly increased aggressive behavior, whereas actual quantity of alcohol ingested was unrelated to aggression. Aggressive dispositions also predicted aggressive behavior.     

An examination of mood effects on positive alcohol expectancies among undergraduate drinkers

Alcohol expectancies have been found to be related to both alcohol use and abuse. To date, very little research has examined whether state biases known to affect the recall and endorsement of other types of information can influence alcohol expectancies. Mood-congruent memory theory and coping theory are reviewed, and are found to make opposing predictions regarding the relationship between state negative and positive affect and endorsement of positive alcohol expectancies. Study 1 (n = 121 undergraduate drinkers) used a correlational approach to show that negative affect predicted increased endorsement of positive alcohol expectancies. Study 2 (n = 55 undergraduate drinkers) used an experimental approach to show that participants assigned to a negative mood induction endorsed more positive alcohol expectancies than participants assigned to a positive mood induction. Together, these findings suggest that state negative affect can produce transient changes making alcohol use appear to be an attractive coping strategy.     

Alcohol‐aggression expectancies and dispositional aggression moderate the relationship between alcohol consumption and alcohol‐related violence

Alcohol consumption increases aggression, but only in some drinkers. This study examines how expectancies for alcohol‐induced aggression and dispositional aggression moderate the link between alcohol consumption and alcohol‐related violence, building on previous studies that have employed limited measures of alcohol‐related violence and included few women. A sample of 212 men and women reported their alcohol consumption, alcohol‐aggression expectancies, dispositional aggression, and incidents of alcohol‐related aggressive acts. Alcohol‐aggression expectancies and quantity of alcohol consumed interacted to predict alcohol‐related aggression. Alcohol‐aggression expectancies covaried with alcohol‐related aggressive acts, particularly in heavier drinkers. Dispositional aggression also correlated with alcohol‐related aggression among heavier drinkers. These results help identify that alcohol might increase aggression only among heavy drinkers who expect alcohol to increase aggression or who are dispositionally aggressive. Aggr.

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.     

Social Anxiety and Specificity of Positive Alcohol Expectancies: Preliminary Findings

This preliminary study examined the relationship between social anxiety and specificity of positive alcohol outcome expectancies (AOE) in a community sample of 62 drinking adults. The sample was divided into subsets of socially anxious (n = 17) and nonsocially anxious (n = 45) men and women. The Drinking Expectancy Questionnaire (DEQ) and Alcohol Expectancies in Social Evaluative Situations Scale (AESES) were used to determine if groups differed in the general positive AOE they hold, or only in AOE specific to social situations. ANOVAs revealed that socially anxious individuals had greater positive AOE specific to social situations (DEQ—Assertion scale and AESES) than nonsocially anxious individuals, with no differences in other positive AOE. Partial correlations controlling for social anxiety revealed that AOE specific to social situations correlated with greater drinking and alcohol dependency levels. Findings indicate that identification of AOE specific to social situations may be useful in classifying socially anxious individuals at risk for alcoholism and as a focus of expectancy challenge strategies for individuals with co-occurring social anxiety and drinking problems.     

Protective behavioral strategies and the relationship between depressive symptoms and alcohol-related negative consequences among college students

Approximately 40% of college students reported engaging in heavy episodic or "binge" drinking in the 2 weeks prior to being surveyed. Research indicates that college students suffering from depression are more likely to report experiencing negative consequences related to their drinking than other students are. The reasons for this relationship have not been well-studied. Hence, the purpose of this study was to determine whether use of protective behavioral strategies (PBS), defined as cognitive-behavioral strategies an individual can use when drinking alcohol that limit both consumption and alcohol-related problems, mediated the relationship between depressive symptoms and alcohol-related negative consequences among college students. Data were obtained from 686 participants from a large, public university who were referred to an alcohol intervention as a result of violating on-campus alcohol policies. Results from structural equation modeling analyses indicated that use of PBS partially mediated the relationship between depressive symptoms and alcohol-related negative consequences. Implications for clinicians treating college students who report experiencing depressive symptoms or consuming alcohol are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved).
