Eye-Tracking and Adolescent Interest in Alcohol Responsibility Messages: The Message Matters.

OBJECTIVE: Through the use of eye-tracking technology, this study explores the efficacy of current alcohol responsibility messages viewed by adolescents and proposes the development of new alcohol warning message design. METHOD: An adolescent sample (N = 121; 72 males) was shown 14 advertisements (4 alcohol, 10 non-alcohol) in randomized order featuring messages modified by type size, type contrast, and message content (a 2 × 2 × 2 factorial design). RESULTS: Results suggested that modifying message content to include direct language and a consequence enhances recall and attention to alcohol responsibility messages among adolescents. No significant differences in attentional outcomes were observed for messages that included variances in type size or type contrast. CONCLUSIONS: Overall, to increase attention to and recall of alcohol responsibility messages, the greatest efficacy lies in varying the message itself, irrespective of size or contrast.

Adolescents' attention to responsibility messages in magazine alcohol advertisements: an eye-tracking approach.

PURPOSE: To investigate whether adolescent readers attend to responsibility or moderation messages (e.g., "drink responsibly") included in magazine advertisements for alcoholic beverages and to assess the association between attention and the ability to accurately recall the content of these messages. METHODS: An integrated head-eye tracking system (ASL Eye-TRAC 6000) was used to measure the eye movements, including fixations and fixation duration, of a group of 63 adolescents (ages 12-14 years) as they viewed six print advertisements for alcoholic beverages. Immediately after the eye-tracking sessions, participants completed a masked-recall exercise. RESULTS: Overall, the responsibility or moderation messages were the least frequently viewed textual or visual areas of the advertisements. Participants spent an average of only .35 seconds, or 7% of the total viewing time, fixating on each responsibility message. Beverage bottles, product logos, and cartoon illustrations were the most frequently viewed elements of the advertisements. Among those participants who fixated at least once on an advertisement's warning message, only a relatively small percentage were able to recall its general concept or restate it verbatim in the masked recall test. CONCLUSIONS: Voluntary responsibility or moderation messages failed to capture the attention of teenagers who participated in this study and need to be typographically modified to be more effective.

An objective means of diagnosing anorexia nervosa and bulimia nervosa using 15N/14N and 13C/12C ratios in hair.

An objective means based on the carbon and nitrogen stable isotope analysis of five hairs per individual is presented for distinguishing between individuals with anorexia nervosa and/or bulimia nervosa from non-clinical individuals (i.e. clinically normal controls). Using discriminant analysis, an algorithm has been developed that provides both sensitivity and specificity of 80% in making diagnoses of individuals with these eating disorders. With further refinements, the results suggest that it may be also possible to distinguish between individuals with anorexia or bulimia. Finally, the study shows the value of conducting blind tests and using larger sample sizes of both control and treatment groups. Both groups are needed to validate the diagnostic value of a method and to provide measures of sensitivity and specificity of any diagnostic test.

Entertainment and music magazine reading and binge drinking among a group of juvenile offenders.

This study examines the relative contribution of exposure to entertainment and music magazines on binge drinking among a group of teenagers under the supervision of a juvenile court system in a medium-sized western United States community. Despite having a large proportion of adolescent readers, entertainment and music magazines typically include a substantial number of advertisements for alcoholic beverages in each issue. Data were collected via a self-report questionnaire administered to 342 juvenile offenders (ages 12-18 years). Three-quarters of our respondents reported they have used alcohol and about 37% indicated they were binge drinkers. As anticipated, binge drinkers were more frequent readers of entertainment and music magazines than non-binge drinkers. Binge drinkers also estimated that larger portions of their classmates used alcohol and would be more accepting of regular drinking than non-binge drinkers. Results of a multivariate logistic regression analysis to predict whether our subjects typically consumed five or more drinks during a drinking episode indicated that perceived ease of access, age, gender, the number of best friends who drink, parental drinking (inversely), and entertainment and music magazine reading frequency were significant predictors of binge drinking. We conclude that the predictive influence entertainment and music magazine reading frequency may actually reflect a selectivity bias among a segment of the youth sub-culture already inclined toward alcohol use and abuse. We recommend that entertainment and music magazine reading should be considered only within the constellation of other risk factors when assessing risk for potential alcohol abuse.

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.

Using "Bud World Party" attendance to predict adolescent alcohol use and beliefs about drinking.

This study explored the association between attendance at the "Bud World Party," a family entertainment venue created by Anheuser-Busch for the 2002 Winter Olympics, and alcohol-related beliefs and current drinking behaviors for a group of 7th and 8th graders who attend a middle school in close proximity to the downtown Salt Lake City plaza where the exhibit and related events were located. Data were collected via a questionnaire administered to 283 students 30 days after the closing ceremonies.. Logistic regression was used to predict recent alcohol consumption. Significant predictors were race (non-white) (OR = 3.9), religiosity (OR = .72), having a parent who drinks (OR = 4.8), the number of best friends who drink (OR = 2.5), and the interaction for "Bud World Party" attendance and gender (OR = 33.2). Post-hoc analysis of the interaction effect indicated that the relationship between "Bud World Party" attendance and recent alcohol consumption is moderated by gender. Girls who visited "Bud World Party" were more likely than the boys to have consumed alcohol in the past 30 days. In addition, the girls who visited "Bud World Party" were more likely to believe that drinking would increase their chances of popularity at school than the students who did not.

Looking for an accurate mirror: a model for the relationship between media use and anorexia.

Quantitative research suggests a relationship exists between anorexia and media messages which depict a "thin-ideal" female stereotype. Despite growing support for that relationship, little is known about the psychological processes and mechanisms involved in that relationship. This study used qualitative methods to explore those processes and mechanism to create a model for understanding the relationship between anorexia and media use. Interviews from 28 female participants were analyzed and coded for temporal, situational, and motivational relationships between the anorexic behaviors and media use. Results suggest an interactive, circular model similar to models used to explain other compulsive and addictive processes.

The relationship between reading beauty and fashion magazines and the use of pathogenic dieting methods among adolescent females.

This study examined the relationship between reading women's beauty and fashion magazines and the use of pathogenic dieting methods (laxatives, appetite suppressants/diet pills, skipping two meals a day, intentional vomiting, and restricting calories to 1,200 or less each day) among 502 high school females. Weak to moderate positive associations were found between reading frequency and each of these unhealthful practices except the use of laxatives. When controlling for anxiety about weight and frequency of regular exercise, however, the original bivariate relations between reading frequency and skipping two meals a day, and reading and intentional vomiting, disappeared. Replication and weak specification effects were found when examining the relationships between reading and taking appetite suppressant/weight control pills, and reading and restricting calories, under the control conditions. These findings suggest that two of the most common adolescent dieting methods--restricting calories and taking diet pills--appear to be influenced by the reading of women's beauty and fashion magazines.
