Emergence of alcohol expectancies in childhood: a possible critical period

Adolescent drinking and driving: etiology and interpretation

In the adolescent population, drinking and driving is an important cause of injury, disability and premature death. A literature review of the demographics and etiology of drinking and drinking/driving reveals: 1) which subgroups of the adolescent population are more likely to drink and drink/drive; 2) where and why adolescents drink and drink/drive; 3) peer and family issues associated with adolescent drinking and drinking/driving; and 4) adolescent expectancies and perceived efficacies associated with drinking and drinking/driving. A discussion of the role of theory and the use of etiologic data in intervention research precedes an overview of several types of school-based alcohol-prevention programs and recommendations for more theory based interventions.

Psychological mechanisms of enhanced risk of addiction in children of alcoholics: a dual pathway?

The background and rationale of a recently started project of the Amsterdam Institute for Addiction Research are outlined. This project is aimed at the psychological mechanisms underlying an enhanced risk of (later) addiction in children of alcoholics and the relationship with childhood psychopathology. A dual pathway mechanism is proposed, in which the type of alcoholism of the parent plays a major role. The child of a multigenerational primary alcoholic parent may suffer from an inherited mild dysfunction of the prefrontal cortex, expressed in neuropsychological and personality characteristics similar to those of the alcoholic parent. These are impulsive, aggressive and reward-seeking behaviour, response perseveration and, in some children, related psychopathology such as conduct disorders. For a child of a secondary alcoholic parent, another mechanism is proposed. In these children, stress and social learning may lead to negative affectivity and repressive coping style, with emotional problems at a later age, and the risk of falling into the "circle of secondary alcoholism". In both pathways, alcohol-related expectancies are suggested to constitute a "final common pathway" between different risk factors and later alcohol abuse. Specific expectancies might be related to different pathways and to gender differences in later drinking patterns.

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 significant 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 U.S. students as compared with the Japanese students.

Television beer advertising and drinking knowledge, beliefs, and intentions among schoolchildren

OBJECTIVES

The relationships between television beer advertising and drinking knowledge, beliefs, and intentions were investigated in a survey of schoolchildren. The research was guided by a theoretical model specifying that awareness of advertising, and not mere exposure, is necessary for it to have an effect on beliefs or behaviors.

METHODS

Participants were a random sample of 468 fifth- and sixth-grade schoolchildren from a northern California community. Data were collected in the home with a combination of self-administered questionnaires and structured interviews.

RESULTS

Nonrecursive statistical modeling indicated that awareness of television beer advertising was related to more favorable beliefs about drinking, to greater knowledge of beer brands and slogans, and to increased intentions to drink as an adult. The effects of advertising awareness on knowledge, beliefs, and intentions were maintained when the reciprocal effects of beliefs, knowledge, and intentions on awareness were controlled.

CONCLUSIONS

The findings suggest that alcohol advertising may predispose young people to drinking. As a result, efforts to prevent drinking and drinking problems among young people should give attention to countering the potential effects of alcohol advertising.

Alcohol expectancies, problem drinking, and adverse health consequences

This study evaluated a measure of positive and negative expected effects of alcohol and their subjective evaluation in the identification of college freshmen at high risk for problem drinking and associated morbidities. It was hypothesized that greater expectations of positive outcomes and fewer negative evaluations of negative outcomes would be associated with reports of heavier drinking and more alcohol-related health problems. College freshmen (n = 328) completed a standardized measure of expectations and subjective evaluations of positive and negative outcomes associated with drinking, and a questionnaire assessing drinking patterns and common alcohol-related health problems. Fifty-two percent of students were male and the mean age was 17.9 years (SD = 0.5). Students' expectations of positive outcomes and their subjective evaluations of both positive and negative outcomes from drinking were significantly correlated with drinking and alcohol-related health problems indices (p < 0.001). Gender, expectation of positive outcomes, and evaluation of negative outcomes explained 29% of the variance in drinking and 15% of the variance in alcohol-related health problems indices. Heavier-drinking students and those reporting more health problems expected more positive effects on their sociability and sexuality (p < 0.03) and were less concerned about cognitive and behavioral impairment as a result of drinking (p < 0.001). Students with more health problems were less concerned that drinking would lead to risk-taking or aggressive behavior (p < 0.003). Positive and negative outcome expectancies and their subjective evaluations accounted for a significant portion of the variability in drinking and alcohol-related health problems.(ABSTRACT TRUNCATED AT 250 WORDS)

Children and alcohol

The literature on what, when, and how young children learn about alcohol and drinking is critically reviewed and key issues are highlighted. Available evidence points to recognition of alcohol, identification of drinking norms and rules, formation of attitudes toward drinking and drinkers, and appreciation of some of the consequences of alcohol consumption as early as the preschool years. Understanding of drinking motives appears to require a level of cognitive development that is not present until about 10 to 12 years of age, although there is a dearth of research on this probably crucial determinant of later decisions to drink. Among the factors involved in the acquisition of alcohol cognitions and dispositions are observational learning via families, media, and peers as well as personal drinking experience. Salience of alcohol and its management in the child's immediate environment appears to be an important moderator/mediator of learning. Application of relevant theory to understanding the development of the meaning of alcohol and drinking in preadolescent children is seen as underdeveloped at this time. However, there are a number of potentially fruitful avenues to pursue which could have important implications for future education and prevention efforts.

The development of alcohol-related expectancies from the age of 12 to the age of 15 for two Swedish adolescent samples

Two hundred seventy-four Swedish students from grades six through nine participated in the first study. The purpose was to explore whether 12-year-old Swedish students (grade six) have formed alcohol-related expectancies prior to any own extensive drinking experience and whether alcohol-related expectancies change from the age of 12 to the age of 15 (grade nine). Results indicated that expectancies are formed at the age of 12 and that most of the expected effects are positive in nature. From the age of 12 to the age of 15 expectancies develop further in a positive direction. Background variables did not affect the results to any major degree. The results from a second, more heterogeneous sample of 146 students from grade six and grade nine, confirmed the general picture. It was concluded that adolescents do hold positive alcohol-related expectancies and that these expectancies become more positive with increasing age.

Alcohol expectancies and behavioral and emotional responses to placebo versus alcohol administration

Forty normal drinking males were recruited for a study of "responses to alcohol." Following the completion of an alcohol use questionnaire that included measures of expectancies of alcohol effects, subjects were randomly assigned to either receive the actual 0.6 g/kg dose of ethanol to bring their peak blood alcohol concentration (BAC) to near 0.075 g/dl or to receive a placebo dose. Neither the subject nor the tester was aware of the condition to which the subject has been assigned. Prior to dosing and at repeated 1/2-hr intervals following dosing, subjects were tested on a battery of motor coordination, perceptual speed, reaction time, and mood measures. Significant alcohol effects were found for several measures, but the only significant interaction of individual differences in expectancies of alcohol effects with alcohol dosing occurred for self-perceived intoxication. Subjects who expected more disinhibition after alcohol dosing and who were administered alcohol reported more intoxication than those expecting less disinhibition, while no expectancy effect was found for subjects administered the placebo.

Alcohol and outcome expectancies: tolerance for socially nonacceptable behaviors

A questionnaire was administered to 200 college men and women. The instrument contained two identical sets of 45 items, each one describing a socially nonacceptable behavior. Subjects indicated whether their tolerance for the described behaviors was altered if they knew that the person was moderately intoxicated and whether they expected changed tolerance from others for inappropriate social behaviors when they themselves acted under moderate influence of alcohol. The general result indicated both reduced expected and displayed tolerance for alcohol-related social transgressions. This was interpreted as nonsupportive of the "time-out" hypothesis, according to which alcohol intoxication functions as an "excuse" for socially unacceptable behaviors. A minority of the respondents, however, both showed and expected extreme tolerance under alcohol and for this minority the "time-out" hypothesis might be valid.
