The contribution of influence and selection to adolescent peer group homogeneity: The case of adolescent cigarette smoking

Understanding the homogeneity of peer groups requires identification of peer groups and consideration of influence and selection processes. Few studies have identified adolescent peer groups, however, or examined how they become homogeneous. This study used social network analysis to identify peer groups (cliques), clique liaisons, and isolates among adolescents in 5 schools at 2 data collection rounds (N = 926). Cigarette smoking was the behavior of interest. Influence and selection contributed about equally to peer group smoking homogeneity. Most smokers were not peer group members, however, and selection provided more of an explanation than influence for why isolates smoke. The results suggest the importance of using social network analysis in studies of peer group influence and selection.

An evaluation of Safe Dates, an adolescent dating violence prevention program.

OBJECTIVES This study assessed the effects of the Safe Dates program on the primary and secondary prevention of adolescent dating violence. METHODS Fourteen schools were randomly allocated to treatment conditions. Eighty percent (n=1886) of the eighth and ninth graders in a rural county completed baseline questionnaires, and 1700 (90%) completed follow-up questionnaires. RESULTS Treatment and control groups were comparable at baseline. In the full sample at follow-up, less psychological abuse, sexual violence, and violence perpetrated against the current dating partner were reported in treatment than in control schools. In a subsample of adolescents reporting no dating violence at baseline (a primary prevention subsample), there was less initiation of psychological abuse in treatment than in control schools. In a subsample of adolescents reporting dating violence at baseline (a secondary prevention subsample), there was less psychological abuse and sexual violence perpetration reported at follow-up in treatment than in control schools. Most program effects were explained by changes in dating violence norms, gender stereotyping, and awareness of services. CONCLUSIONS The Safe Dates program shows promise for preventing dating violence among adolescents.

Assessing the Long-Term Effects of the Safe Dates Program and a Booster in Preventing and Reducing Adolescent Dating Violence Victimization and Perpetration

OBJECTIVES This study determined 4-year postintervention effects of Safe Dates on dating violence, booster effects, and moderators of the program effects. METHODS We gathered baseline data in 10 schools that were randomly allocated to a treatment condition. We collected follow-up data 1 month after the program and then yearly thereafter for 4 years. Between the 2- and 3-year follow-ups, a randomly selected half of treatment adolescents received a booster. RESULTS Compared with controls, adolescents receiving Safe Dates reported significantly less physical, serious physical, and sexual dating violence perpetration and victimization 4 years after the program. The booster did not improve the effectiveness of Safe Dates. CONCLUSIONS Safe Dates shows promise for preventing dating violence but the booster should not be used.

Family Structure as a Predictor of Initial Substance Use and Sexual Intercourse in Early Adolescence.

Research on the relationship between family structure and the use of controlled substances by children has produced inconsistent results. Furthermore some authors have suggested that the confounding influence of socioeconomic characteristics may be largely responsible for the positive associations that have been observed. A 2-year prospective study of 2102 US young adolescents in 10 southeastern cities was used to assess the relationship between family structure (intact single- parent or stepparent) and whether cigarettes alcohol marijuana and sexual intercourse had ever been tried. Logistic regression results show significantly higher levels of ever-usage for children of nonintact families. These differences are not diminished when age sex race and mothers education are controlled. The results imply that children of disrupted families are at a higher risk of initiating the use of controlled substances and engaging in sexual intercourse and that a firmer understanding of the mechanisms that underlie this association is needed.

Assessing the Effects of the Dating Violence Prevention Program “Safe Dates” Using Random CoefficientRegression Modeling

The Safe Dates Project is a randomized trial for evaluating a school-based adolescent dating violence prevention program. Five waves of data were used to examine the effects of Safe Dates over time including primary and secondary prevention effects, moderators, and mediators of program effects. Using random coefficients models, with multiple imputation of missing data, significant program effects were found at all four follow-up periods on psychological, moderate physical, and sexual dating violence perpetration and moderate physical dating violence victimization. Marginal effects were found on sexual victimization. Effects on severe physical perpetration at all four follow-up periods were moderated by prior involvement in that type of violence. Primary and secondary prevention effects were found and the program was equally effective for males and females and for whites and non-whites. Program effects were mediated by changes in dating violence norms, gender-role norms, and awareness of community services.

Typologies of Adolescent Dating Violence Identifying Typologies of Adolescent Dating Violence Perpetration

Acts scales, the most common way of measuring partner violence, have been criticized for being too simplistic to capture the complexities of partner violence. An alternative measurement approach is to use typologies that consider various aspects of context. In this study, the authors identified typologies of dating violence perpetration by adolescents. They conducted in-depth interviews with 116 girls and boys previously identified by an acts scale as perpetrators of dating violence. They provided narrative descriptions of their dating violence acts. For boys and girls, many acts considered violent by the acts scale were subsequently recanted or described as nonviolent. From the narratives, they identified four types of female perpetration that were distinguished by motives, precipitating events, and the abuse history of the partners. One type of perpetration accounted for most acts by boys. The findings are discussed relative to dating violence measurement, prevention and treatment, and development of theory.

Effect of parental smoking classification on the association between parental and adolescent smoking

Prior studies of the relationship between smoking by parents and their children have considered only current smoking by parents. In this study of 12- to 14-year-old adolescents, however, lifetime parental smoking was more strongly correlated with adolescent smoking than was current parental smoking. Indeed, lifetime parental smoking was as strongly correlated as peer smoking with adolescent smoking, and peer smoking is often considered to be the main determinant of adolescent smoking. These findings suggest that the relative role of parent smoking in adolescent smoking has been underestimated, and that new explanations for the association between parental and adolescent smoking are necessary.

Are the correlates of cigarette smoking initiation different for black and white adolescents

BACKGROUND Studies of adolescent smoking suggest that the causes of smoking initiation may differ for Blacks and Whites. METHODS Correlates of smoking initiation were examined among 1,277 nonsmokers, ages 12-14, who completed questionnaires in their homes. The analyses examined relationships between smoking initiation and 11 explanatory variables using logistic regression with the combined sample and with Black and White samples. RESULTS Over two years, 24 percent of Whites and 14 percent of Blacks started to smoke. Whites were more likely to start smoking at age 12 and Blacks at age 14. Having a best friend who smoked increased the odds of initiating smoking over twofold for Whites but had no effect on the odds of smoking for Blacks. CONCLUSIONS Whites initiate smoking earlier than Blacks and are more likely to be influenced by friend behavior.

The Social Ecology of Adolescent Alcohol Misuse.

A conceptual framework based on social ecology, social learning, and social control theories guided identification of social contexts, contextual attributes, and joint effects that contribute to development of adolescent alcohol misuse. Modeling of alcohol use, suggested by social learning theory, and indicators of the social bond, suggested by social control theory, were examined in the family, peer, school, and neighborhood contexts. Interactions between alcohol modeling and social bond indicators were tested within and between contexts. Data were from a longitudinal study of 6,544 students, 1,663 of their parents, and the U.S. Census. All contexts were uniquely implicated in development of alcohol misuse from ages 11 through 17 years, and most alcohol modeling effects were contingent on attributes of social bonds.

Parental and peer characteristics as modifiers of the bond-behavior relationship: an elaboration of control theory.

Three bonds are at the core of Hirschis control theory: attachment to parents, commitment to conventional activities, and belief in the conventional rules of society. Control theory does not include parental and peer attitudes and behaviors, variables that frequently are implicated in adolescent behavior. This study examines whether parental and peer behaviors and attitudes modify bond/behavior relationships. Adolescent cigarette smoking is the behavior of interest. Panel data from a probability sample of 685 adolescents shows that the relationship between attachment and adolescent smoking is modified by parental smoking; the relationship between commitment to conventional activities and adolescent smoking is modified by fathers smoking; but the relationship between belief in conventional rules and adolescent smoking is not modified by parental or peer variables. We conclude that control theory needs to encompass parental behavior when considering adolescent smoking behavior.
