Prototype perception and smoking: are negative or positive social images more important in adolescence?

It is suggested that a more profound understanding of cigarette smoking among adolescents should include the social images they have of smokers. The main goal of the present study was to investigate the role of smoker prototypes in adolescents' smoking status and to compare the role of negative and positive smoker images. Data were collected from high school students in two counties of the Southern Plain Region of Hungary (N=548; ages between 14 and 21 years). The self-administered questionnaires contained items on sociodemographics, smoking occurrence, and smoker prototypes. Factor analysis revealed three smoker prototypes: a negative prototype (e.g., dull, childish), a positive social appearance prototype (e.g., cool, popular), and a positive individual competence prototype (such as smart, independent) all with satisfactory reliability. Odds ratios suggest that the role of the negative prototypes for nonsmokers is greater than the role of positive prototypes for smokers. For boys, positive individual competence prototype also seems to be important. Health promotion programs should focus on fostering negative social images in prevention.

Ethnic pride and self-control related to protective and risk factors: test of the theoretical model for the strong African American families program.

OBJECTIVE: To test a theoretical model of how ethnic pride and self-control are related to risk and protective factors. DESIGN: A community sample of 670 African American youth (mean age = 11.2 years) were interviewed in households. MAIN OUTCOME MEASURES: Measures of cigarette smoking, alcohol use, and sexual behavior (lifetime to past month). RESULTS: Structural modeling analyses indicated parenting was related to self-control and self-esteem, and racial socialization was related to ethnic pride. Self-control and self-esteem variables were related to levels of deviance-prone attitudes and to perceptions of engagers in, or abstainers from, substance use and sexual behavior. The proximal factors (behavioral willingness, resistance efficacy, and peer behavior) had substantial relations to the criterion variables. Participant gender and parental education also had several paths in the model. Results were generally similar for the 2 outcome behaviors. CONCLUSIONS: In this population, self-esteem and self-control are related to parenting approaches and have pathways to attitudes and social perceptions that are significant factors for predisposing to, or protecting against, early involvement in substance use and sexual behavior.

The Strong African American Families Program: a cluster-randomized prevention trial of long-term effects and a mediational model.

The Strong African American Families Program, a universal preventive intervention to deter alcohol use among rural African American adolescents, was evaluated in a cluster-randomized prevention trial. This 7-week family skills training program is based on a contextual model in which intervention effects on youth protective factors lead to changes in alcohol use. African American 11-year-olds and their primary caregivers from 9 rural communities (N = 332 families) were randomly selected for study participation. Communities were randomized to prevention and control conditions. Intent-to-treat analyses indicated that fewer prevention than control adolescents initiated alcohol use; those who did evinced slower increases in use over time. Intervention-induced changes in youth protective factors mediated the effect of group assignment on long-term changes in use.

A theory-based dual-focus alcohol intervention for preadolescents: the Strong African American Families Program.

This study examined mediators of the Strong African American Families Program, a randomized, dual-focus prevention trial intended to delay the onset of alcohol use and reduce alcohol consumption among rural African American youths. More specifically, it demonstrated that changes in consumption 2 yrs after the intervention were mediated through 2 different paths, a social reaction path and a reasoned/intention path. The social reaction path provided evidence that relative to the control condition, the intervention decreased children's willingness to drink by making their images of drinkers less favorable. The reasoned/intention path provided evidence that the intervention influenced the children's intentions to drink by increasing targeted parenting behaviors related to alcohol. Furthermore, the data demonstrate that these changes in willingness and intentions were independently associated with alcohol consumption at the follow-up, and they suggest that a dual-process model approach that targets both intentions and willingness can be more successful than either approach alone.

Pubertal maturation and early substance use risks among African American children.

Using 2 waves of longitudinal data collected from approximately 870 African American adolescents, this study examined (a) changes in early risk factors for substance use during transition to early adolescence, including perceived prototypes of substance-using peers, willingness and intention to use substances, number of substance-using peers, and youths' own actual substance use; (b) the relationship between pubertal timing and these substance use risks; and (c) the interaction between pubertal timing and peer substance use in predicting the risks. Results showed that, first, risks for substance use increased, particularly among girls, during the transition to early adolescence. Children's prototypic images of substance users became increasingly favorable during this transitional period; a greater number of them were willing and intended to use substances during the transition to early adolescence; and an increased number of early adolescents and their friends began to use substances. Second, these changes were significantly more likely to occur among early maturing girls. Third, early physical maturation interacted with peer substance use to affect these changes.

The strong African American families program: prevention of youths' high-risk behavior and a test of a model of change.

In this study, the efficacy of the Strong African American Families Program (SAAF) was tested. The trial, which included 332 families, indicated that families who participated in SAAF experienced increases over time in regulated, communicative parenting; increases in targeted parenting behaviors, according to youths' reports; and low rates of high-risk behavior initiation among youths. Changes in regulated, communicative parenting mediated the intervention's impact on youths' recognition of changes in parenting, which in turn was linked to changes in youths' high-risk behavior.

Alcohol use in motion pictures and its relation with early-onset teen drinking.

OBJECTIVE: Little is known about the impact of viewing depictions of alcohol in entertainment media on adolescent drinking behavior. Our aims were to assess drinking in a sample of popular contemporary movies and to examine the association of movie alcohol exposure with early-onset drinking in an adolescent sample. METHOD: We conducted a school-based cross-sectional survey (N=4655) with longitudinal follow-up of never-drinkers (N=2406) involving adolescents ages 10-14 years and recruited from 15 New Hampshire and Vermont schools. Screen depictions of alcohol use were timed for each of 601 popular contemporary movies. Each adolescent was asked if he/she had seen a unique list of 50 movie titles, randomly selected from the larger pool. Movie alcohol use was summed for movies the adolescent had seen, adjusted to reflect exposure to the larger pool and modeled as a continuous variable. RESULTS: Ninety-two percent of the movies in the sample depicted drinking; median screen time for movie alcohol use was 2.5 minutes (interquartile range [IQR]: 0.9-5.0 minutes). Median exposure to movie alcohol use from the 601 movies was 8.6 hours (IQR: 4.6-13.5 hours). Overall 23.1% of the cross-sectional sample had tried alcohol, and 14.8% of initial nondrinkers had tried alcohol at the follow-up assessment. We found statistical evidence to support a curvilinear association between higher exposure to movie alcohol use and increased risk of prevalent and incident alcohol use, with a statistically significant linear and quadratic effect, and suggesting a higher dose-effect relationship at lower movie alcohol exposure levels compared to higher levels. The linear and the quadratic associations remained strong and significant in cross-sectional and prospective models after controlling for sociodemographics (grade in school, school, gender, parent education), personality characteristics of the adolescent (sensation seeking, rebelliousness, self-esteem), school performance, parenting style, and smoking experimentation, suggesting that exposure to movie alcohol use is an independent risk factor for early-onset alcohol use. CONCLUSIONS: This study provides the first evidence for an association between exposure to movie alcohol use and early-onset teen drinking. The association is moderate in effect size and independent of a number of potential confounders. Because exposure to movie alcohol use is common, it may have important population implications as a potentially modifiable risk factor.

A culture-based study of personal and social influences of adolescent smoking.

BACKGROUND: A range of factors have been found to influence the onset and maintenance of smoking among adolescents. The aim was to explore interrelationships among adolescent smoking and certain personal influences (academic achievement, life satisfaction and future-orientedness) and social influences (hostility, social comparison and perceived friends' smoking) using a cultural perspective. METHODS: The study surveyed high school students aged 13-20, a total sample of 2387 adolescents from randomly selected classes in urban and metropolitan areas from Szeged (Hungary), Lublin and Warsaw (Poland), Izmir (Turkey) and Ames, Iowa (USA). The self-administered questionnaire contained items on smoking, sociodemographics, life satisfaction, future-orientedness, academic achievement, hostility, social comparison and perceived friends' smoking. RESULTS: The frequency of smoking proved to be the highest among Hungarian (58.7%) and Polish (57.6%) adolescents, while the occurrence was 22.1% among US and 23.6% among Turkish adolescents. Across the countries, high life satisfaction, academic achievement, future orientedness and social comparison were related to lower rates of smoking. Perceived friends' smoking was a strong influence of adolescent smoking in all samples. Only paths from academic achievement and perceived peers' smoking differed across the countries. CONCLUSION: Findings suggest that interrelationships between adolescents' smoking and its social and personal influences are similar across all countries as a part of the developmental processes of adolescence. These findings point to the importance of both personal and social influences of adolescent smoking, which interact in a complex model, regardless culture or smoking rates.

Images of smokers and willingness to smoke among African American pre-adolescents: an application of the prototype/willingness model of adolescent health risk behavior to smoking initiation.

OBJECTIVE: This study used the prototype/willingness model of adolescent health risk behavior to examine factors related to onset of smoking. METHODS: Two waves of data were collected from a panel of 742 African American children (mean age=10.5 at Wave 1) and their primary caregivers. Measures included cognitions outlined by the prototype model as well as self-reports of smoking by the parent and child. RESULTS: Structural equation modeling revealed a pattern consistent with expectations generated by the prototype model. The relation between contextual, familial, and dispositional factors-including neighborhood risk, parental smoking, and children's academic orientation-and the initiation of smoking at Wave 2, two years later, was mediated by the children's cognitions. Primary among these cognitions were the children's images of smokers and children's willingness to smoke. CONCLUSIONS: Smoking cognitions mediate the impact of important distal factors (such as context, family environment, and disposition) on the onset of smoking in children. Perhaps more important, it is possible to predict onset of smoking in African American children as young as age 10 by assessing the cognitive factors suggested by the prototype model.

Effects of UV photographs, photoaging information, and use of sunless tanning lotion on sun protection behaviors.

OBJECTIVES: To examine the efficacy of UV photographs and information about photoaging (eg, wrinkles and age spots) for increasing the sun protection intentions and behaviors of young adults and to determine whether any effects of this appearance-based intervention could be enhanced by providing a non-UV alternative for achieving a tan (ie, sunless tanning lotion). DESIGN: Randomized control trial with 1-month follow-up. SETTING: Two universities in Southern California. PARTICIPANTS: A volunteer sample of 146 college students, 91.1% of whom completed the "surprise" 1-month follow-up. INTERVENTION: A UV facial photograph and a brief videotape describing the causes and consequences of photoaging. The study tested the effects of the photoaging information/UV photographic intervention only, the intervention plus use of sunless tanning lotion, and a control condition. MAIN OUTCOME MEASURES: Participants sun protection intentions as assessed immediately after the intervention and sun protection behaviors during the month after the intervention as assessed during a surprise telephone follow-up. RESULTS: The intervention resulted in significantly stronger sun protection intentions (P<.001) and greater sun protection behaviors (P<.05) relative to controls. Furthermore, the group that also used sunless tanning lotion tended to engage in greater sun protection behaviors than the group that received the intervention alone (P<.08). CONCLUSION: The UV photographic intervention holds promise as a cost-effective approach to motivate practices that may ultimately result in health benefits (ie, reduced skin cancer rates).

Using UV photography to reduce use of tanning booths: a test of cognitive mediation.

Two laboratory studies were conducted in which a new type of intervention was used to reduce ultraviolet radiation (UV) exposure from tanning booth use among college students (Time 1 Ns=70 and 134). The intervention uses UV photography to highlight the damage to facial skin caused by previous UV exposure. When the authors controlled for baseline measures of booth use, students in both studies who viewed their UV photographs reported less booth use at a follow-up session 3-4 weeks later than did students not shown a copy of their photograph. Also, in both studies, the decline in use was significantly mediated by a Tanning Cognition Index composed of variables suggested by the prototype-willingness (prototype) model of health risk: tanning attitudes, tanner prototypes, and willingness to engage in risky UV exposure.

Smoking cessation: social comparison level predicts success for adult smokers.

The affiliation preferences of 151 adult heavy smokers who joined smoking cessation groups were assessed at the 1st group session and were then used to predict their smoking status 6 and 12 months later. Those who preferred to be in groups with other smokers who were having relatively little trouble quitting were more likely to be successful than were those who preferred others who were having more difficulty quitting. This prospective effect was mediated by psychological distancing from the image of the typical smoker: Preference for others who were doing well was associated with a decrease in perceived similarity to the typical smoker, which, in turn, was associated with successful cessation. Implications of these findings for cessation groups and social comparison theory are discussed.

Families and risk: prospective analyses of familial and social influences on adolescent substance use.

Parental, peer, and older siblings' contributions to adolescents' substance use were investigated with 2 waves of panel data from 225 African American families. Structural equation modeling showed that older siblings' behavioral willingness (BW) to use substances at Time 1 (T1) predicted target adolescents' Time 2 (T2) use, controlling for other T1 variables. Regression analyses revealed an interaction between targets' and siblings' BW, such that targets were more likely to use at T2 if both they and their siblings reported BW at T1. This interaction was stronger for families living in high-risk neighborhoods. Finally, siblings' willingness buffered the impact of peer use on targets' later use: Low sibling BW was associated with less evidence of peer influence.

Using images to increase exercise behavior: prototypes versus possible selves.

This study investigated the impact of health-related prototypes and possible selves on exercise behavior. In addition, this study examined if these effects might be moderated by individual differences-specifically social comparison (SC) and consideration of future consequences (CFC). One hundred and fifty-two students participated in all three waves of the study-premanipulation, manipulation, and follow-up. As expected, results indicated that individuals who were high on SC and exposed to a prototype manipulation increased their exercise behavior at follow-up. Furthermore, individuals who were future-oriented and exposed to a possible selves manipulation increased their exercise behavior at follow-up. Overall, results revealed that health images have an important impact on health behavior. Implications for behavior change are discussed.

Perceived discrimination and substance use in African American parents and their children: a panel study.

The relation between perceived racial discrimination and substance use was examined in a panel of 684 African American families, using the prototype-willingness model of adolescent health risk (F. X. Gibbons, M. Gerrard, & D. Lane, 2003). Discrimination was concurrently and prospectively related to use in the parents and the children (mean age=10.5 years at Wave 1). The discrimination-->use relation in the parents was mediated by distress (anxiety and depression). Among the children, the relation was mediated by distress as well as their risk cognitions (favorability of their risk images and their willingness to use) and the extent to which they reported affiliating with friends who were using substances. Each of these relations with discrimination was positive. In contrast, effective parenting was associated with less willingness and intention to use. Theoretical and applied implications of the results are discussed.

Context and cognitions: environmental risk, social influence, and adolescent substance use.

This study examined the cognitions thought to mediate the impact of context on adolescent substance use and also the extent to which context moderates the relations between these cognitions and use. Risk cognitions and behaviors were assessed in a panel of 746 African American adolescents (M age 10.5 at Wave 1, 12.2 at Wave 2). Results indicated that adolescents living in high-risk neighborhoods were more inclined toward substance use and more likely to be using at Wave 2. These context effects were mediated by the adolescents' risk cognitions: their risk images, willingness to use, and intentions to use. Also, context moderated the relation between willingness and use (the relation was stronger in high-risk neighborhoods) but it did not moderate the intentions to use relation.

Effects of appearance-based interventions on sun protection intentions and self-reported behaviors.

Two appearance-based interventions designed to increase sun protection intentions and behaviors were evaluated. Sixty-eight college students in Experiment 1 and 76 beachgoers in Experiment 2 were randomly assigned to receive or not receive a photoaging (premature wrinkling and age spots) information intervention and, separately, to receive or not receive a novel ultraviolet (UV) photo intervention that makes the negative-appearance consequences of UV exposure more salient. Both experiments indicated that the UV photo intervention significantly increased intentions to use sunscreen in the future. A follow-up conducted with the beach sample indicated that UV photo information also produced greater protective behaviors for incidental sun exposure and that the combination of UV photo and photoaging information resulted in substantially lower reported sunbathing.

It's about timing and change: pubertal transition effects on symptoms of major depression among African American youths.

Effects of early physical maturation and accelerated pubertal changes on symptoms of major depression were examined in 639 African American children. Three rival hypotheses, early timing, off-time, and stressful change, were tested using 2 waves of data (mean ages = 11 and 13 years). The pubertal effect operates differently according to children's gender and age. For girls, early maturation was consistently associated with elevated levels of depressive symptoms. For boys, early maturers manifested elevated levels of depression only at age 11, but these symptoms subsided by age 13. Boys who experienced accelerated pubertal growth over time displayed elevated symptom levels. Results support the early timing hypothesis for girls and the stressful change hypothesis for boys. Time at assessment is critical when examining boys' pubertal transition.
