The influence of social environment and social image on adolescent smoking.

This purpose of this article is to explore differences by gender and school grade in patterns of association among social influences and tobacco use. Data from the 1999 (N = 15,038) and 2000 (N = 35,828) National Youth Tobacco Survey (American Legacy Foundation, 1999, 2000), a nationally representative, repeated cross-sectional survey, were used in the analysis. The authors compared effects on adolescent smoking. Direct paths from social environment to current smoking increased from middle school to high school. Indirect paths with social image mediating this relationship revealed a smaller increase. The pattern was constant across subsamples. Social image of smokers mediated the influence of social environment on adolescent smoking. Social image had a greater effect on smoking among middle school boys and high school girls.     

Relationship between stages of smoking acquisition and environmental factors among junior high school students

To study the relationship of stages of smoking acquisition and environmental factors, 757 Japanese junior high school students (390 boys and 367 girls) anonymously answered a questionnaire regarding the four stages of smoking acquisition (precontemplation, contemplation, preparation, and action stages) and environmental factors of smoking behavior. Analysis showed that the influence of advertising and students' interpersonal situations on smoking behavior increased from the precontemplation stage to the action stage.     

Immediate antecedents of cigarette smoking: an analysis of unrestricted smoking patterns

Theory suggests that cigarette smoking is under stimulus control and that affect is a key trigger for smoking. A previous study (S. Shiftman et al., 2002) showed little relationship between affect and smoking, but this relationship could have been suppressed by the impact of smoking restrictions. The study evaluated these associations in a 1988 sample that was subject to few smoking restrictions. Smokers (N = 28) not seeking treatment used palmtop computers to record context and affect prior to smoking (n = 2217 observations) and also at random times when not smoking (n = 2,380). Comparisons showed little relationship between smoking and affect. Smoking was associated with particular activities and locations. Urge to smoke was the strongest predictor of smoking. The results replicated the findings of S. Shiffman et al. (2002).     

Parental and school effects on students' occupational exploration: A longitudinal and multilevel analysis

The study examines school and parental influences on adolescents' occupational exploration. Analyses of data from 859 6th, 8th, and 10th graders attending high- and lower-track high schools in the German federal state of Thuringia suggested more extensive exploration among students closer to the school-to-work transition. Besides cross-sectional effects of parenting and achievement orientation at school, acceptance and openness students experienced in class predicted increases of their exploratory behaviors. Multilevel analyses showed, however, that school effects operated on the level of subjective perceptions (individual level), but not on the level of intersubjective reality (classroom level). Implications for attempts to foster and facilitate exploration are discussed.     

The effects of self-modeling on cigarette smoking behavior

Two studies of self-modeling are described. Study 1 investigated whether self-modeling would inhibit cigarette smoking behavior. Fourteen cigarette smokers (four males and 10 females) served as subjects for a repeated-measures design. In the self-modeling condition, the subjects watched themselves on a television monitor while smoking; in the control condition, they watched a short cartoon film on the same monitor, also while smoking. The following were measured: (1) the amount of tobacco consumed, (2) the amount of time lit cigarettes were in contact with the subjects’ lips, and (3) the subjects’ physiological responses (GSRs). Study 2 investigated the role of cognitive factors in self-modeling. It followed much the same self-modeling procedures as Study 1. However, unlike Study 1, it incorporated a manipulated cognitive variable: attitudes toward cigarette smoking. Self-modeling reduced the amount of smoking relative to the control condition in Study 1. In Study 2 it was found that cognitive factors influenced the amount of smoking. Smoking increased in subjects supplied with information favorable to smoking, whereas it decreased in those supplied with information unfavorable to smoking. These findings and additional research on the efficacy of self-modeling relative to other procedures suggest the importance of cognitive factors in self-modeling.     

The natural history of cigarette smoking: predicting young-adult smoking outcomes from adolescent smoking patterns

Assessed the magnitude of risk that adolescent cigarette smoking carries for adult smoking. Using a longitudinal, prospective design, results indicate that even infrequent experimentation in adolescence significantly raises the risk for adult smoking and that regular (at least monthly) adolescent smoking raises the risk for adult smoking by a factor of 16 compared to nonsmoking adolescents. Relative risk was also increased by an early onset of smoking and by a stable, uninterrupted course from experimentation to regular smoking. Relative risk did not significantly vary by age or sex. The continuity of smoking behavior between adolescence and adulthood supports the importance of primary prevention programs directed at adolescent populations.     

The effects of shock as a punisher for cigarette smoking

An attempt was made to reduce the cigarette smoking of three subjects by means of a special cigarette case that delivered aversive shock when opened. The number of cigarettes smoked was recorded by a counter in the cigarette case. The validity of the counter readings as a measure of smoking was obtained by a specially designed participant-observer technique. It was found that the rate of smoking decreased as a function of the intensity of the shock. Also, the smoking returned to its previously unpunished level after the shock punisher was discontinued. Both of these findings confirm the results of laboratory studies of punishment of simpler responses and extends them to more complex responses in a naturalistic situation. Surprisingly, the duration for which the apparatus was worn also decreased as a function of the intensity of the shock. This finding reveals that this aversive shock technique produced avoidance behavior that prevents the technique from having extensive applicability for eliminating smoking. The same limitation may apply to the use of aversive shock for eliminating other undesirable behaviors.     

Immediate antecedents of cigarette smoking: an analysis from ecological momentary assessment

The authors assessed the association between smoking and situational cues, including affect, in real-world contexts. Using ecological momentary assessment, 304 smokers monitored ad-lib smoking for 1 week, recording each cigarette on palm-top computers. Generalized estimating equations contrasted 10,084 smoking and 11,155 nonsmoking situations. After controlling for smoking restrictions, smoking was strongly related to smoking urges and modestly related to consumption of coffee and food, the presence of other smokers, and several activities. Smoking was unrelated to negative or positive affect or to arousal, although it was associated with restlessness. Thus, in daily life, affect appears to exert little influence over ad-lib smoking in heavy smoking adults.     

Behavioral economics of drug self-administration. II. A unit-price analysis of cigarette smoking.

In behavioral economics, the ratio of response requirement to reinforcer magnitude is referred to as unit price. Previous research with nonhuman subjects has demonstrated that (a) comparable amounts of food are consumed at the same unit price even though different response requirements and reinforcer magnitudes comprise that unit price and (b) increases in unit price decrease food consumption in a positively decelerating fashion. The present study assessed the generality of these findings to the cigarette smoking of 5 human volunteers. During approximately 18 3-hr sessions, various combinations of response requirement (fixed-ratio 200, 400, and 1,600) and reinforcer magnitude (1, 2, and 4 puffs per bout) were arranged. Consumption (i.e., the number of puffs) generally was comparable at the same unit price independent of the response requirement and reinforcer magnitude comprising that unit price. In addition, increasing unit price generally decreased consumption in a positively decelerating fashion. These results extend the generality of the unit-price analysis to human cigarette smoking. Moreover, these results further support the position that reinforcer magnitude and response requirement are functionally equivalent and interact to determine consumption. The concept of unit price, by integrating and summarizing the effects of those two operations, provides a more parsimonious explanation of the results than do separate evaluations of the effects of response requirement and reinforcer magnitude.     

Hungry for love: the influence of self-regulation on infidelity

The current research examines the effect of self-regulation on the likelihood of committing infidelity. Thirty-two college students in exclusive romantic relationships interacted through a private chat room with an opposite-sex confederate. Prior to this interaction, a food-restriction task depleted half the participants of self-control. As predicted, depleted levels of self-regulation increased the likelihood of infidelity. Specifically, depleted participants were more likely to both accept a coffee date from and supply a personal telephone number to the confederate than non-depleted participants. Weakened self-control may be one potential cause for the levels of infidelity occurring in romantic partnerships today.     

Radon and cigarette smoking: perceptions of this synergistic health risk.

Past approaches to the measurement of the perceived risk of combined hazards have failed to demonstrate awareness of synergy (S. E. Hampson et al., 1998; D. Hermand, E. Mullet, & B. Coutelle, 1995; D. Hermand, E. Mullet, & S. Lavieville, 1997). Respondents (N = 650) were provided with information about the synergistic risk of lung cancer from the combination of smoking and radon, and their risk perceptions were assessed on two occasions. At Time 1, using Likert-type scales, there was no evidence of synergistic risk perception. At Time 2, using a scale based on the appraisal of relative risk with anchors allowing for the expression of synergy, the combined hazard of radon and smoking was rated as significantly more of a health risk than the single hazards. The findings are discussed in terms of methodological issues in assessing synergistic risk.     

Preventing smoking: evaluating the potential effectiveness of cigarette warnings.

We examined the potential effectiveness of U.S. government cigarette warnings in preventing adolescent smoking. In Study 1, 112 seventh graders rated the effectiveness of four currently required warnings and four possible other warnings and answered questions about the meaning of certain words in the warnings. In Study 2, 115 seventh graders attempted to recall the four current warnings; in Study 3, 103 eighth and ninth graders read all eight warnings one day and tried to recall them the next day. In Study 4, 25 seventh graders participated in a focus session in which they discussed the effectiveness of each of the eight warnings. The results of the studies showed that the four different evaluation strategies had convergent validity and that two current warnings and two proposed warnings are significantly more potentially effective than the other two current warnings. Our results also provided information about why some warnings are more potentially effective than others.     

Food reinforcement and eating: a multilevel analysis

Eating represents a choice among many alternative behaviors. The purpose of this review is to provide an overview of how food reinforcement and behavioral choice theory are related to eating and to show how this theoretical approach may help organize research on eating from molecular genetics through treatment and prevention of obesity. Special emphasis is placed on how food reinforcement and behavioral choice theory are relevant to understanding excess energy intake and obesity and how they provide a framework for examining factors that may influence eating and are outside of those that may regulate energy homeostasis. Methods to measure food reinforcement are reviewed, along with factors that influence the reinforcing value of eating. Contributions of neuroscience and genetics to the study of food reinforcement are illustrated by using the example of dopamine. Implications of food reinforcement for obesity and positive energy balance are explored, with suggestions for novel approaches to obesity treatment based on the synthesis of behavioral and pharmacological approaches to food reinforcement.     

Adolescent personality antecedents of adult cigarette smoking: a longitudinal study

Comprehensive personality assessments, made independently for early and late adolescence, were employed to predict smoking onset and maximum number of cigarettes smoked per day as reported by adult smokers. Also, comparisons were made between adult smokers and nonsmokers. The results indicate that men who had been more sexually active as adolescents smoked more but that women who had been more emotionally constricted and under more conflict as adolescents were heavier smokers. Smoking started earlier for men who had showed little self-awareness and a rather macho orientation during their adolescence; early-smoking women tended to have been conventionally feminine. Personality differences between future smokers and nonsmokers were few but showed similar sex differences. The results suggest that manifesting once traditional sex-role characteristics for both adolescent boys and girls presages early onset and heavier adult cigarette smoking. Preventive antismoking educational campaigns aimed at youth might be guided by these findings because they suggest some motivational bases that may find later expression in smoking practices.     

Measurements of lip pressure exerted on a cigarette during normal smoking

Measurements were made of the pressure exerted by human lips on the filter of a cigarette during normal smoking conditions using a small, fluid-filled bulb attached to a low-compliance pressure transducer. In two series of measurements, the mean lip pressure and standard error were 34.2 (±2.6) and 35.8 (±3.1) torr respectively. These pressures compared favorably with those applied by the Cambridge holder (used in the standard FTC testing procedure), but were much lower than the pressures exerted by the Filtrona and Borgwaldt holders, both of which are constructed from a rigid cylindrical housing with a segment of latex tube mounted inside. Pressures measured by these two holders were in close agreement with the pressures predicted by a nonlinear theoretical model for the distention of latex rubber tubes.     

Impact of a social influence intervention on condom use and sexually transmitted infections among establishment-based female sex workers in the Philippines: a multilevel analysis.

The authors assessed the relative impact of structural and social influence interventions on reducing sexually transmitted infections (STIs) and HIV risk behavior among female sex workers in the Philippines (N = 897). Four conditions included manager influence, peer influence, combined manager-peer influence, and control. Intervention effects were assessed at the establishment level in multilevel models because of statistical dependencies among women employed within the same establishments. Control group membership predicted greater perceived risk, less condom use, less HIV/AIDS knowledge, and more negative condom attitudes. Combination participants reported more positive condom attitudes, more establishment policies favoring condom use, and fewer STIs. Manager-only participants reported fewer STIs, lower condom attitudes, less knowledge, and higher perceived risk than peer-only participants. Because interventions were implemented at the city level, baseline and follow-up city differences were analyzed to rule out intervention effects due to preexisting differences.

Multiple victimization of Spanish adolescents: a multilevel analysis

Multiple victimization in adolescence is an issue that has received little research attention. Furthermore, adolescents are particularly vulnerable to victimization in different contexts. The aim of this study is to analyze correlates of multiple victimization in three contexts (home, school, and street). The following forms of victimization were considered: stealing, hitting, insulting, threatening, blackmailing, and weapon intimidation. Multiple victimization correlates explored were: sex, age, public/private school, socioeconomic status, quality of family relationships, and antisocial behavior. A probabilistic sample of 1,908 adolescents (ages 13 to 18) was used. Multilevel analyses were conducted to separate correlates at the individual level from those operating at the contextual level. Results show that gender, quality of family relationships, and deviant behavior were related to multiple victimization in adolescence.     

The impact of school transitions: A focus for preventive efforts

The relationship between cumulative or single school transfers and a student's academic adjustment was explored. The school records of 250 high school students were examined and school transfers due to either residential mobility or the normative school change from eighth to ninth grade were identified. Correlations between the cumulative number of school transfers in a student's history and their ninth-grade academic performance and attendance record were computed for both ethnic and sex subgroups. Analyses of variance for repeated measures were performed to assess the impact of any single school transition occurring at different points in the child's development. Correlational analyses indicated that high rates of school mobility were significantly related to poor academic performance, particularly for black and Hispanic students. Analyses of variance revealed that while no single school transition due to residential mobility in Grades 1 through 8 had a significant impact on the student's posttransfer adjustment, the normative transition to high school was significantly related to lowered school performance and increased absences, particularly for students with a history of repeated school transfers and for black students.
