T wo-year longitudinal study expectancies and drinking adolescents of alcohol am ong Norwegian

A bstract A im s. The potential importance of alcohol outcome expectancies in the initiation and maintenance of drinking has been supported by studies showing that these expectancies are present before drinking begins, and that they predict drinking both cross-sectionally and longitudinally. Although initiation of drinking behavior may be influenced by expectancy, subsequent drinking experience may modify expectations. We used structural modeling techniques to investigate the relative influence of expectancy and drinking in a three-wave longitudinal study of Norwegian adolescents . D esign. Survey incorporating self-administered questionnaires . Setting. Twenty-two schools in Hordaland County on the west coast of Norway . Participants. Nine hundred and twenty-four seventh-grade students; 45.7% female . M easurem ents. Alcohol use (frequency, quantity, drunkenness); the Norwegian version of the Alcohol Expectancy Questionnaire for adolescents . Findings. Among students who were already drinkers upon entry into the study, expectations of positive social effects of alcohol predicted drinking longitudinally. Among those who began drinking during the study, these social expectancies predicted drinking initiation, but drinking also influenced subsequent expectancy in the early stages of drinking . C onclusions. These results support a reciprocal relationship of drinking to positive expectancy, highlighting the importance both of expectancies on influencing drinking, and of early drinking experiences on the development of positive expectancies.     

Relationship Between Age and Drinking Patterns and Drinking Problems Among Japanese, Japanese-Americans, and Caucasians

Comparing alcohol consumption patterns by age and gender among Japanese in Japan and Japanese-Americans and Caucasians in the United States, this study examined the associations between age and both heavy drinking and social problems using logistic regression for each ethnic group of male current drinkers. As reported in previous studies of Caucasians, men drink more alcohol than women, older respondents are more likely than younger ones to be abstainers, and the percentages of heavier drinkers and problem drinkers are higher among the young than among older people. Although Japanese-Americans reported consuming less alcohol than Caucasians, their drinking patterns by age were similar:among both United States populations, younger respondents are at higher risk for drinking problems than older respondents, even when alcohol consumption and sociodemographic variables are controlled by logistic regression. However, this association of age and drinking patterns and drinking problems is not universal. Japanese men consumed more alcohol and had a higher proportion of heavier drinkers in the middle age groups; the association between age and drinking problems also varied in this group. In addition to aging, sociocultural factors such as drinking norms probably account for the differences in drinking behavior among different age groups. This study may stimulate further cross-cultural comparison of drinking patterns and problems.     

Socio-environmental influences on adolescents' alcohol outcome expectancies: a prospective analysis

AIMS: To investigate the prospective influence of social influence and social bonding variables on the development of alcohol outcome expectancies among adolescents with and without drinking experience. DESIGN: Longitudinal data from students in the control schools of a field trial designed to evaluate a school-based drug prevention program. SETTING: A total of 19 middle schools in South Dakota, USA. MEASUREMENTS: An alcohol outcome expectancy scale administered to 1410 students in grades 8 and 9. After using confirmatory factor analysis (CFA) to develop an expectancies measure, multiple-group (grade 8 drinkers versus grade 8 non-drinkers) path analysis was used to model 9th grade alcohol expectancies. Grade 8 social influence and bonding variables were used as predictors, controlling for grade 8 expectancies. FINDINGS: At the bivariate level, peer and adult influences and social bonding variables were related consistently to alcohol outcome expectancies among drinkers and non-drinkers. A bivariate relationship between alcohol advertising and alcohol expectancies was found among drinkers only. In the multivariate model, greater alcohol use by important adults predicted independently increased alcohol positivity among drinkers; greater perceived approval of alcohol use by parents and peers predicted diminished perceived potency of alcohol among non-drinkers. Advertisement exposure and social bonding variables were not independent predictors of alcohol expectancies in the multivariate model. CONCLUSIONS: These findings suggest that attempts to alter adolescents' alcohol expectancies are likely to fail unless they address the influence of immediate social models on these beliefs.     

The alcohol-related problems survey: identifying hazardous and harmful drinking in older primary care patients

OBJECTIVES: Older adults can incur problems at low levels of alcohol consumption because of age-related physiological changes, declining health and functional status, and medication use. We have developed and tested a screening measure specifically for older people, the Alcohol-Related Problems Survey (ARPS), to identify older adults with these risks. DESIGN: Survey. SETTING: Academic and community primary care clinics. PARTICIPANTS: Five hundred forty-nine current drinkers aged 65 and older, mostly white with high school or more education. MEASURES: Alcohol use was classified as harmful, hazardous, or nonhazardous depending upon consumption alone or combined with selected comorbidities and medication use. Harmful drinking (including alcohol abuse or dependence) means the presence of problems (e.g., hypertension, adverse drug events, legal problems) due to drinking. Hazardous drinking means risks for problems are likely. Nonhazardous drinking poses no known risks for problems. RESULTS: Eleven percent of subjects were harmful drinkers and 35% were hazardous drinkers. Harmful drinking was more common in men than women and in persons younger than 75 than those aged 75 and older. Similar proportions of men and women and younger and older age groups were hazardous drinkers. Most harmful drinkers were identified by their use of alcohol with their comorbidity, whereas most hazardous drinkers were identified by their use of alcohol with medications. Test-retest reliability was substantial (kappa = 0.65). CONCLUSION: Physicians are urged to screen for alcohol-related problems in older persons. The ARPS reliably identifies harmful, hazardous, and nonhazardous drinking in older adults resulting most often from the interaction between alcohol and disease and medication use.     

Projected Alcohol Dose Influences on the Activation of Alcohol Expectancies in College Drinkers

Background:  Alcohol expectancies have been linked to drinking behavior in college students, and vary according to a number of factors, including projected dose of alcohol. Research using Multidimensional Scaling (MDS) suggests that drinking may be influenced by activation of differing expectancy dimensions in memory, yet studies have not examined expectancy activation according to projected alcohol doses.
Methods:  The present study used Individual Differences Scaling (INDSCAL) to map expectancy networks of college students ( n  = 334) who imagined varied drinking at high and low alcohol doses. Expectancy activation was modeled by dose, as well as by gender and by drinking patterns (typical quantity, blood alcohol content, heavy episodic drinking, and alcohol consequences). Expectancies were organized along positive–negative and arousal–sedation dimensions. Anticipation of a high dose of alcohol was associated with greater emphasis on the arousal–sedation dimension, whereas anticipation of a lower dose was associated with greater emphasis on the positive–negative dimension.
Results:  Across heavy, medium, and light drinkers, expectancy dimensions were most distinguishable at higher doses; activation patterns were more similar across drinking groups at lighter doses. Modest evidence for the influence of gender on activation patterns was observed. Findings were consistent across alcohol involvement indices.
Conclusions:  These data suggest that both dimensionality and context should be considered in the refinement of interventions designed to alter expectancies in order to decrease hazardous drinking.     

Validation of multidimensional scaling-based modeling of alcohol expectancies in memory: age and drinking-related differences in expectancies of children assessed as first associates

BACKGROUND: As evidence has accumulated that alcohol expectancies mediate the effects of other drinking antecedents, attempts to understand the mechanism by which expectancies influence behavior have focused on modeling memory processes. Previous expectancy work, however, has used relatively indirect approaches to retrieve and model information stored in memory. By using the method most recommended by memory researchers for directly obtaining uncontaminated memory contents, we assessed children's expectancies and related findings to empirically modeled organization and activation of expectancies in memory based on scaled instruments. METHODS: Individual interviews were conducted with 462 children in 2nd through 5th grades, and surveys were completed by 1,003 children in 3rd, 6th, 9th, and 12th grades. Interviews and surveys consisted of a measure designed to retrieve participants' first expectancy associate to an alcohol prompt and several drinking quantity/frequency questions. RESULTS: Older and higher drinking children were more likely to report positive expectancies as their first associate to an alcohol prompt. Age and drinking-based findings were consistent with organizational structure, dimension emphasis shift, and paths of association identified by prior multidimensional scaling techniques. CONCLUSIONS: Consumption of alcohol among children corresponded to accessibility of positive expectancies in memory. In addition, the use of multidimensional scaling to study the organization and activation of alcohol expectancies in memory was validated.     

Gender and alcohol consumption: patterns from the multinational GENACIS project

Aims   To evaluate multinational patterns of gender- and age-specific alcohol consumption.
Design and participants   Large general-population surveys of men's and women's drinking behavior ( n 's > 900) in 35 countries in 1997–2007 used a standardized questionnaire (25 countries) or measures comparable to those in the standardized questionnaire.
Measurements   Data from men and women in three age groups (18–34, 35–49, 50–65) showed the prevalence of drinkers, former drinkers, and lifetime abstainers; and the prevalence of high-frequency, high-volume, and heavy episodic drinking among current drinkers. Analyses examined gender ratios for prevalence rates and the direction of changes in prevalence rates across age groups.
Findings   Drinking per se and high-volume drinking were consistently more prevalent among men than among women, but lifetime abstention from alcohol was consistently more prevalent among women. Among respondents who had ever been drinkers, women in all age groups were consistently more likely to have stopped drinking than men were. Among drinkers, the prevalence of high-frequency drinking was consistently greatest in the oldest age group, particularly among men. Unexpectedly, the prevalence of drinking per se did not decline consistently with increasing age, and declines in high-volume and heavy episodic drinking with increasing age were more typical in Europe and English-speaking countries.
Conclusions   As expected, men still exceed women in drinking and high-volume drinking, although gender ratios vary. Better explanations are needed for why more women than men quit drinking, and why aging does not consistently reduce drinking and heavy drinking outside Europe and English-speaking countries.     

Increased drinking in a metropolitan city in China: a study of alcohol consumption patterns and changes

AIMS: To investigate alcohol drinking among urban Chinese and any changes between 2002 and 2005. DESIGN: Two identical face-to-face interviews were carried out with two random samples with 2327 and 2613 respondents, respectively. SETTING: Respondents were selected randomly from Wuhan City, Hubei province, China, between May and June 2002, and June and August 2005. PARTICIPANTS: Fifteen to 65-year-old urban Chinese adults. MEASUREMENTS: Prevalence of drinking, frequency of drinking, typical occasion quantity, volume of annual consumption and heavier drinking were the main measures. FINDINGS: Nearly three-quarters (90% for men and 55% for women) were current alcohol drinkers in 2005, and the prevalence of drinking alcohol had increased significantly since 2002 among both men and women; the largest increases occurred in the younger group (18-19 years) and among older women. There was no change in the frequency of drinking, the average quantities consumed by drinkers and the volume of absolute alcohol consumed by drinkers over this 3-year period. However, reflecting the increased prevalence of drinkers, the median volumes of absolute alcohol consumed in the sample as a whole had increased significantly. Older males were more likely to be categorized as larger-quantity drinkers: 30-65-year-old men accounted for 63%. There was also an increase over time in the proportion of larger-quantity drinkers: the proportion of male larger-quantity drinkers increased from 27% in 2002 to 35% in 2005. CONCLUSIONS: In the urban setting of Wuhan, over the time-period 2002-05, there was an increase in prevalence of drinkers, particularly among younger people and older women. The average frequency and quantities consumed by drinkers did not change over this period; among drinking men the volumes of alcohol consumed were comparable to those in much more saturated commercial alcohol markets. The results did, however, show an increase over time in the proportion of older men who were engaged in heavier drinking and, in 2005, the proportion exceeded that in more saturated markets. These data suggest that, given the relatively high levels of consumption among established drinking groups, increases in the prevalence of drinkers over time may result in increases in harm if effective policies are not implemented.     

A view through the gateway: expectancies as a possible pathway from alcohol to cannabis

Aim. The aim of this study was to test the hypothesis that cannabis outcome expectancies would be more positive in adolescents who drink alcohol than in non-drinkers. Participants and setting. The participants in the study were 4544 11-16-year-olds attending eight secondary schools located in the north-west midlands of England. Procedure. Participants completed an anonymous self-report questionnaire that incorporated sections designed to tap adolescents' expectancies of positive and negative outcomes of alcohol and cannabis use, together with other questions relating to substance use and associated issues. Results. Four reliable six-item scales were derived, and used to measure positive and negative alcohol and cannabis outcome expectancies. Negative expectancies were relatively stable across age and frequency of substance use, particularly for alcohol. However, positive expectancies for both substances increased markedly with age and, independently, with frequency of use. Positive alcohol and cannabis outcome expectancies were meaningfully related to expectancies of future substance use, and to measures of problem drug use and resistance to peer influence, supporting the validity of these expectancy measures, and their possible value as diagnostic screening instruments. The main hypothesis of the study was supported: among respondents who reported never using cannabis, positive cannabis outcome expectancies increased and negative cannabis outcome expectancies decreased with increasing frequency of alcohol use. Conclusions. The results are consistent with a version of the 'gateway hypothesis' for the relationship between alcohol and cannabis use (alcohol use leads to changes in cannabis expectancies and thereby to cannabis use), but a proper test of the hypothesis requires a longitudinal study.     

The Hispanic Americans Baseline Alcohol Survey (HABLAS): Predictors of Alcohol Attitudes and Expectancies in Hispanic National Groups

Background: Multiple theoretical frameworks identify attitudes and expectancies as important predictors of alcohol behavior. Few studies have examined demographic predictors of these evaluative and belief‐based cognitive mediators in the general population, and none have examined them in large‐scale studies of Hispanics, a group at higher risk for drinking behavior and problems. This study probes the extent to which dimensions of attitudes and expectancies share common demographic predictors in a large sample of Puerto Ricans, Cuban‐Americans, Mexican‐Americans, and South/Central Americans. Methods: The 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS) used a multistage cluster sample design to interview 5,224 individuals randomly selected from households in Miami, New York, Philadelphia, Houston, and Los Angeles. This study focused on 2,773 respondents self‐identified as current drinkers. Multiple linear regression was used to identify predictors of positive and negative dimensions of attitudes and expectancies, controlling for various background variables. Results: Religious affiliation selectively predicted alcohol attitudes, with Catholics having more positive and fewer negative attitudes than other religious groups. Hispanic group selectively predicted alcohol expectancies, with Cuban‐Americans having less positive and less negative expectancies than other groups. Being U.S.‐born or male predicted more positive attitudes and expectancies, but birthplace and gender did not predict negative dimensions of attitudes or expectancies. Higher acculturation and more education were linked to a decreased tendency to agree with any item. Age was positively and negatively associated with negative expectancies and positive attitudes, respectively, and having never been married, higher income, and unemployment were each linked to fewer negative attitudes. Conclusions: Although there is some overlap, attitudes and expectancies are influenced by different sociodemographic variables. Positive and negative dimensions of those constructs also show distinct patterns of relations. Prevention and treatment programs targeting cognitive mediators of behavior should be mindful of these differential determinants and future modeling endeavors should incorporate them.     

Are older hazardous and harmful drinkers less likely to participate in health-related behaviors and practices as compared with nonhazardous drinkers?

OBJECTIVES: To describe the (1) prevalence of at-risk drinking and participation in health-related behaviors and practices and (2) associations of at-risk drinking with other health-related behaviors and practices among older persons completing a health-risk appraisal for the elderly (HRA-E). DESIGN: Cross-sectional study using data from a self-administered, mailed survey sample. SETTINGS: Persons from three organizations were surveyed: (1) the American Association of Retired Persons; and (2) a large medical group and (3) a community-based senior health center in southern California. PARTICIPANTS: 1,889 persons age 55 years and older. MEASUREMENTS: The HRA-E included items on health characteristics, drinking behaviors (including amount of alcohol use and two alcoholism screening measures: the CAGE (Cut down, Annoyed, Guilty, Eye opener) and Short Michigan Alcoholism Screening Test-Geriatric version (SMAST-G), and participation in selected health-related behaviors and practices. Social drinkers were defined as those who drank fewer than 14 drinks weekly and screened negative on the CAGE (defined as two or more "no" responses) and SMAST-G. Hazardous drinkers drank fewer than 14 drinks weekly and screened negative. Harmful drinkers drank fewer than 14 drinks weekly and screened positive. Possible at-risk drinkers drank 14 or more drinks weekly and screened positive. Least squares regression models were used to assess the effects of hazardous, harmful, and possible at-risk drinking on each of the health-related practices and behaviors. We also conducted these analyses using three other definitions of social, possible at-risk, hazardous, and harmful drinking. RESULTS: Of all respondents, 40% were social drinkers, 3% were harmful drinkers, 2% were hazardous drinkers, and 11% were possible at-risk drinkers. Hazardous, harmful, and possible at-risk drinkers commonly reported driving after drinking or being driven by someone who had been drinking (67%, 76%, and 64% respectively). Harmful and possible at-risk drinkers were more likely than social drinkers to smoke and were less likely to use seatbelts regularly. These findings were observed regardless of how the drinking groups were defined. CONCLUSION: All groups of at-risk drinkers more commonly engaged in selected adverse health-related behaviors and practices than did social drinkers.     

From the Eyes of the Beholder: Alcohol Expectancies and Valuations as Predictors of Hazardous Drinking Behaviors among Female College Students

Research has shown that drinking expectancies are associated with alcohol use among college students; however, the bulk of these studies have focused exclusively on researcher-labeled “positive” or “negative” expectancies rather than on the student's valuation (i.e., rating of desirability) of these expectancies. The present study examined the utility of expectancies and valuations in predicting hazardous alcohol use in a sample of 330 female college students (mean age = 20.0; 18–25). Hierarchical regression analyses revealed that negative expectancies and favorable valuations of negative and positive expectancies were predictive of elevated hazardous use (controlling for age, athletic membership, and peer use). Expectancy valuations accounted for additional variance in the model beyond that of expectancies. The present findings shed light on the utility of expectancies and valuations of expectancies in predicting hazardous alcohol use among female college students. Future research directions and potential implications for prevention efforts are discussed.     

The roles of alcohol-related self-statements in social drinking

Recent literature showed that expectancies or cognitions have been proposed as a major factor in influencing the amount of alcohol an individual consumes and the behavioral consequences following consumption. However, how alcohol expectancies influence alcohol consumption is unclear; this paper reports two studies of the relationship. Study I examined the relationship between alcohol consumption and alcohol-related positive and negative self-statements in 110 social drinkers. The results showed that, in a nondrinking situation, the alcohol expectancies and variables measuring consumption and alcohol-related problems were correlated. Also, subjects who perceived their "alcoholic sets" as negative consumed more than those who perceived theirs as positive. Study II investigated changes in self-statement responding in 8 light and 8 heavy drinkers in a "normal" pub drinking situation. The results showed that alcohol-dependent self-statements in the light drinkers were relatively stable across time and between drinking and nondrinking environments. However, the alcohol-dependent self-statements of heavy drinkers became more negative during the drinking session. Furthermore, the degree and nature of such changes appeared to be related to alcohol-associated problems and consumption.     

Public opinion on the health benefits of moderate drinking: results from a Canadian National Population Health Survey

Aims. To explore beliefs about the health benefits of drinking alcohol in the Canadian population. Design. Secondary analysis of data from a national population health survey. Participants. Canadians age 12 or older (weighted n = 72375) in all provinces but Alberta excluding those living in remote regions, native reserves and armed forces bases. Measures. Responses to questions concerning the definition of moderate drinking and the belief that moderate drinking can be good for health. Self-reports of age, gender, province of residence, quantity and frequency of drinking, health problems and indicators of alcohol dependence. Findings. Fifty-seven per cent of respondents believed that moderate drinking has health benefits. Forty-seven per cent defined moderate drinking as drinking less than one drink a day and believed this to be good for health. Twelve per cent defined moderate drinking as one or more drinks a day and believed this is good for health. Belief in the health benefits of moderate drinking was more common among men, those age 45 or older, residents of Ontario and Quebec, more frequent drinkers and those with ischaemic heart disease. Those who believed in the health benefits of at least one drink a day were more often males, older persons and frequent, heavy drinkers. Conclusions. Belief in the health benefits of moderate drinking is generally associated with a conservative definition of moderate drinking. However, some drinkers at risk for alcohol problems may be influenced to drink by the belief that this can have health benefits or use this belief as an excuse for drinking.     

Drinking expectancies and motives: a genetic study of young adult women

BACKGROUND: Constructs such as drinking expectancies (beliefs regarding the effects of alcohol) and motives (drinking alcohol to achieve a valued end) have been shown to be associated with various stages of alcohol use behaviors. However, little is known of the extent to which genetic and environmental influences contribute to individual differences in expectancies and motives. METHODS: Using data from 3,656 young adult same-sex female twins, we examined the association between measures of drinking expectancies and motives and drinking behaviors. Using twin models, we estimated the extent to which genetic, shared and non-shared environmental factors influenced individual differences in expectancies and motives and also tested whether the extent of the genetic and environmental contributions on expectancies varied across abstainers and users of alcohol. RESULTS: Expectancies predicted initiation of alcohol use. Both motives and expectancies were associated with frequency and quantity of alcohol consumption and drinks-to-intoxication. There was no evidence for heritable influences on expectancies and enhancement motives, with familial similarity for these traits being due to shared environment. Heritable influences on social, coping and conformity motives ranged from 11% to 33%. When expectancies were stratified by alcohol use, significant heritable influences (31-39%) were found for cognitive-behavioral impairment and risk-taking/negative self-perception (RT/NSP) in abstainers only, while environmental influences contributed to familial variance for other measures of expectancies in alcohol users. CONCLUSIONS: Environmental influences (both familial and individual-specific) shape alcohol expectancies, while heritable influences may predispose to motives for drinking. Individual differences in expectancies are moderated by alcohol use, suggesting that sources of individual differences in expectancies may vary in drinkers versus abstainers.     

Measuring average alcohol consumption: the impact of including binge drinks in quantity-frequency calculations

AIMS: Average daily alcohol consumption is usually calculated based on self-reports of the quantity (number of drinks consumed per drinking-day) and frequency (number of drinking-days) of alcohol consumption within a given time period. However, this method may underestimate average daily alcohol consumption (and in turn, the prevalence of heavy drinking), because studies demonstrate that respondents do not typically include binge drinking occasions in estimates of their 'usual' or 'average' daily alcohol consumption. DESIGN: We used the Behavioral Risk Factor Surveillance System (BRFSS), an annual random-digit telephone survey of US adults aged 18 years or older, to estimate average daily alcohol consumption using standard quantity-frequency questions, and then recalculated this measure by including self-reports of binge drinking. The proportion of respondents who met a standard, sex-specific definition of heavy drinking based on average daily alcohol consumption was then assessed nationally and for each state. FINDINGS: Compared to standard quantity-frequency methods, including binge drinks in calculations of average daily alcohol consumption increased the relative prevalence of heavy drinking among all adults by 19% to 42% (depending on the method used to estimate the number of drinks per binge). Among binge drinkers, the overall prevalence of heavy drinking increased 53% relative to standard quantity-frequency methods. As a result, half of women binge drinkers and half of binge drinkers aged 55 or older met criteria for heavy drinking. CONCLUSIONS: Including binge drinks (especially the application of age- and sex-specific estimates of binge drinks) in the calculation of average daily alcohol consumption can improve the accuracy of prevalence estimates for heavy drinking among US adults, and should be considered to increase the usefulness of this measure for alcohol surveillance.     

Alcohol Norms, Expectancies, and Reasons for Drinking and Alcohol Use in a U.S. Versus a Japanese College Sample

Two hundred eighty-two students at Arizona State University in the U.S. and 339 students at Okayama University in Japan completed a questionnaire on their alcohol use, expectancies of the effects of alcohol on their own and others' moods and behaviors, the desirability of these effects, norms of signifiant others for levels of alcohol use and the subject's desire to comply with these norms, and reasons for drinking and not drinking alcohol. Although frequencies of current drinkers versus abstainers did not differ between the two samples, the U.S. students began regular alcohol use at a significantly earlier age, currently drank more alcohol, had higher alcohol expectancies for emotional responses, and endorsed more celebratory reasons for drinking than their Japanese counterparts. U.S. students, however, had lower expectancies for flushing and lower perceived norms for drinking. Hierarchical multiple regressions performed using data from the current drinkers indicated that expectancies of disinhibition and especially aggressiveness after alcohol use, alcohol norms, celebratory (but not pathological) reasons for drinking, and reasons for not drinking were more predictive of reported levels of alcohol use among the US. students as compared with the Japanese students.     

Desire for alcohol and outcome expectancies as measures of alcohol cue-reactivity in social drinkers

Aims. To assess the responsiveness of questionnaire measures of desire to drink and alcohol outcome expectancies. Design. A subjective alcohol cue-reactivity paradigm (alcohol cue: sight, smell, taste) was used with a 2 X 2 between-subject design (n = 88), drink type (soft/alcoholic) and order of assessment (desire-expectancy/expectancy-desire). Covariance analysis controlled for quantity of recent alcohol consumption. Setting. A quiet alcohol research suite. Participants. Eighty-eight male and female social drinking students, recruited for a 'taste preference' survey. Measures. Three composite measures using questionnaire totals and subscales: of desire (DAQ), positive expectancy (AEQ) and negative expectancy (NAEQ). Timeline Follow-back procedure for recent consumption . Findings. Subjective cue-reactivity was found for the DAQ total score and the subscales 'strong intentions and desires' and 'negative reinforcement'. Expectancies did not demonstrate alcohol cue-reactivity. Conclusion. The DAQ and subscales are sensitive measures of alcohol cue-reactivity in social drinkers. Potential uses of the subjective cue-reactivity procedure with multi-factorial representations of cue reaction are identified.     

Cognitive processes in adolescent drug use: the role of positivity bias and implications for prevention policy

Recent investigations of the role of expectations about the effects of alcohol in drinking behavior suggest that there is a functional relationship between expectancies and alcohol use. Specifically, greater positive expectancies are related to heavier drinking patterns. In contrast, expectations about the negative consequences of alcohol use seem to be unrelated to drinking behavior. These differential roles of positive and negative expectancies as mediators of alcohol use reflect the robust phenomenon of positivity bias in human information processing. The theoretical and clinical implications of this phenomenon with respect to adolescent drug use are discussed.
