Alcohol expectancies and drinking characteristics in parents of children with attention deficit hyperactivity disorder.

Alcohol expectancies, drinking characteristics, and their association were examined in 587 adults: 431 parents of children with attention deficit hyperactivity disorder (ADHD) and 156 parents of children without ADHD. In addition to examining both traditional and parenting-specific alcohol expectancies for these adults, risk variables cutting across the two groups were considered: single parenthood and male gender. Few differences in mean expectancy levels were found between parents of children with and without ADHD, between single and married mothers, and between men and women. Furthermore, expectancies did not predict drinking differently across groups. However, there was some support for the utility of assessing parental expectations of alcohol's effects on interactions with children, and there were robust and interesting effects of socioeconomic status on expectancies and drinking. Single mothers also reported consuming higher quantities of alcohol than married mothers. Findings are discussed in terms of the link between ADHD and alcoholism, the ability of alcohol expectancies to explain drinking differences between high risk groups, the effect of socioeconomic status on these variables, and single motherhood as a vulnerability factor for increased drinking.

Beyond stress and arousal: a reconceptualization of alcohol-emotion relations with reference to psychophysiological methods.

In this review, the authors examine how psychophysiological research might better contribute to understanding the effects of alcohol on human emotion. They propose that future studies would benefit from greater use of contemporary theories of emotion that emphasize a dimensional structure of affective expression, incorporating the parameters of emotional arousal and emotional valence. Evidence suggests that, although alcohol exerts an overall dampening effect on arousal, it appears to modulate emotional response through its effects on higher order associative processes rather than at the level of primary brain motivational systems. They discuss methodological implications of this multidimensional, multilevel approach and suggest that alcohol-induced physiological changes need to be investigated as dynamic response patterns rather than isolated events tied to solitary measures.

Alcohol and human emotion: a multidimensional analysis incorporating startle-probe methodology.

The effect of alcohol intoxication on emotional response was investigated using a model of emotion that includes both arousal and valence dimensions. Thirty-six university students were exposed to multiple presentations of photographic slides selected to elicit distinctive emotional reactions ranging from very pleasant to very unpleasant; half of them received a moderate (approximately .75 ml/kg) dose of ethanol. The students' psychophysiological responses indicated that both general startle reactivity and autonomic indices specific to emotional arousal were diminished by alcohol. However, the affective modulation of startle, occurring with emotional states manipulated by slides with distinct valences, remained intact. These findings suggest that "stress-response dampening" by alcohol may involve a nonspecific attenuation of arousal reactions evident for positive as well as negative stimuli and that theories of motivation for drinking that are based on mood alteration may need refinement.

The alcohol-aggression stereotype: a cross-cultural comparison of beliefs.

University students (N = 1,008) in eight countries participated in a survey aimed at mapping cross-cultural alcohol expectancies. Multisample structured means analysis was applied to compare changes in aggressive behaviors believed to occur in connection with drinking after "many" alcoholic drinks. Most subjects expressed the belief that intoxication was associated with greater aggressiveness, but there were significant national differences unrelated to self-reported alcoholic beverage preference, frequency of drinking to intoxication, or rates of personal involvement in episodes of alcohol-related aggression. Thus, the expectation that drinking leads to aggression may be determined to a significant extent by contextual factors and cultural traditions related to alcohol use.

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.

Aggression in boys with attention deficit-hyperactivity disorder: methylphenidate effects on naturalistically observed aggression, response to provocation, and social information processing.

High and low-aggressive boys with attention deficit-hyperactivity disorder (ADHD) were compared and the effects of methylphenidate were examined on measures from three domains of aggression: (1) directly observed verbal and nonverbal aggressive behaviors exhibited in the context of a day treatment program, (2) aggressive responding when provoked during a laboratory task, and (3) social information processing patterns exhibited on tasks designed to tap the putative cognitive components of aggression. The high-aggressive (HA) and low-aggressive (LA) subgroups differed significantly on observational measures of aggression and on the laboratory provocation task, but the HA group showed more deviant cognitions on only one of the numerous measures of social information processing. Regarding medication effects on the direct observation measures, methylphenidate decreased aggression for both subgroups. On the laboratory provocation task, methylphenidate had only minimal effects. Significant drug effects were obtained on only two recall social information processing measures.

Person perception as a function of drinking behavior, gender and sex role stereotypes.

Gender and the level of drinking of the protagonist in a vignette were systematically varied to examine the effects of these variables on the inferences 400 undergraduates drew about the personal attributes and future of the character. Results showed that gender of the target did not significantly affect judgments about the protagonist, but perceptions of the character were strongly influenced by the alcohol-related behaviors attributed to him or her in the vignette. Evaluations of the protagonist generally became less favorable as drinking level increased. Abstainers were also viewed more positively than at least some comparison groups of drinkers on most measures. Although heavier drinkers were often stigmatized, they were also seen as having more fun. Subject gender, sex role attributes and attitudes toward women failed to influence judgments about the protagonists, but raters' own drinking habits did have an impact. Heavier drinkers showed a tendency to rate heavier drinking protagonists more favorably than did lighter drinkers. Implications of these results for prevailing theories about norms and evaluations affecting drinkers are discussed.

Beverage preference, beverage type and subject gender as determinants of alcohol consumption in the laboratory.

Effects of beverage preference, beverage type and subject gender on ad libitum consumption of alcoholic beverages in the laboratory were evaluated. Undergraduate social drinkers (18 male, 18 female), with equal numbers of each gender stating a preference for beer, wine or mixed drinks, were selected. Subjects participated in three separate 30-minute ad lib drinking sessions and were presented with one of the three types of alcoholic beverage at each session. Data on total volume of beverage and of absolute ethanol consumed as well as blood alcohol concentration (BAC) attained were collected in each session. Subjects preferring wine or mixed drinks drank more alcohol and reached higher BACs when imbibing their beverage of choice than when drinking non-preferred beverages. Subjects preferring beer, however, showed no differences on these drinking measures as a function of beverage type. Men's reports of routine alcohol use had a high positive correlation with actual alcohol consumption observed in the laboratory, whereas for female subjects the correlation was near zero. Implications for interpretation of past ad lib drinking studies and the planning of future ones are discussed.

Disturbances in sexual role performance of chronic alcoholics: an analysis using Roy's adaptation model.

Scientific evidence that sheds light on the disturbances in sexual role performance experienced by chronic alcoholics is discussed within the framework of Roy's adaptation model of nursing. The multiple etiologic factors contributing to disturbed sexual role performance are identified within each adaptation mode, with emphasis on the interrelationships between them. Nursing diagnoses are then suggested.

Levels of adult alcohol consumption induced by interactions with child confederates exhibiting normal versus externalizing behaviors.

Investigated levels of distress and alcohol consumption in Ss interacting with problematic vs non-problematic child confederates. Social drinkers were randomly assigned to interact with boys trained to enact behaviors characteristic of either normal or attention-deficit disorder/conduct disorder (ADD/CD) children. Mood data were collected before and after the interaction. Ss engaged in ad lib beer consumption for 20 min, while anticipating another interaction with the same boy. Children in the ADD/CD role produced comparably distressed moods for both male and female Ss. However, only men drank to higher blood-alcohol levels in the ADD/CD vs. normal child condition. Results suggest that higher rates of drinking observed in fathers of ADD/CD children may be partly a function of their particular response to the distress associated with interactions with such children.

Drinking and creativity: objective and subjective effects.

A literature characterized by considerable speculation but a paucity of empirical studies prompted this experiment on the relation between drinking and creativity. After being queried about how they believed alcohol would affect their creative performance, 40 male undergraduate social drinkers were assigned to one of four treatments in a balanced placebo design. Those actually receiving alcohol consumed a mixture containing .6 g of ethanol per kg of body weight. All subjects then completed the entire Figural portion and the Unusual Uses subtest of the Verbal portion of the Torrance Tests of Creative Thinking. Posttesting explored subjects' own evaluations of their creative products and the kinds of attributions they made about factors contributing to the outcomes. Results showed minimal effects of beverage manipulations on measured creativity even when a priori belief and concurrent mood scores were covaried. However, those individuals who thought they had received alcohol gave significantly more positive evaluations of their creative performances than did subjects who believed they were in the non-alcohol treatments. Subjects did not attribute changes in creativity to drinking. Theoretical and practical implications of these findings were discussed.
