RESUMEN
In a quasi-experiment, we examine whether changing schools during the transition from 8th to 9th grade influences adolescent delinquency, using a sample of more than 14,000 students in 26 public school districts (PROSPER study). The dataset follows students for eight waves from 6th through 12th grade and facilitates a unique, direct comparison of students who change schools with those who remain in the same school during this period. Results show that students who transition between schools report significantly less delinquency after the shift than those who do not, and that this difference persists through 10th grade. This decline is most pronounced when adolescents from multiple middle schools move to a single high school (i.e., multifeeder transitions). Students who transition between schools have fewer delinquent friends and participate in less unstructured socializing following the change in school environment, which partially mediates their reduced delinquency. Results provide some support for theories of differential association and routine activities. Our findings highlight the role of a crucial, yet understudied, life transition in shaping adolescent delinquency. The results from this quasi-experiment underscore the potential of alterations in social context to significantly dampen juvenile delinquency throughout high school.
RESUMEN
We examine gender differences in the extent to which the social network processes of peer influence and friend selection explain why adolescents tend to exhibit similar risky behaviors as their friends for three problem behaviors (smoking, drinking, and delinquency). Using dynamic Stochastic Actor-Oriented Models (SAOMs), we analyze five waves of data on a large sample of 13,214 adolescents from 51 friendship networks. While both processes explain patterns of risky activities for girls and boys, the delinquent behavior of girls is more susceptible to influence and girls are especially likely to select friends who have similar smoking behaviors to their own.
RESUMEN
This randomized trial tested a strategy originally developed for school settings, the Pax Good Behavior Game (PAX GBG), in the new context of afterschool programs. We examined this approach in afterschool since 70% of all juvenile crime occurs between the hours of 3-6 pm, making afterschool an important setting for prevention and promotion. Dual-career and working families need monitoring and supervision for their children in quality settings that are safe and appropriately structured. While substantial work has identified important features of afterschool programs, increasing attention is being given to how to foster quality. PAX GBG, with its focus on shared norms, cooperative teams, contingent activity rewards, and liberal praise, could potentially enhance not only appropriate structure and supportive relationships, but also youth self-regulation, co-regulation, and socio-emotional development. This study examined the PAX GBG among 76 afterschool programs, serving 811 youth ages 5-12, who were diverse in race-ethnicity, socio-economic status, and geographic locale. Demographically matched pairs of afterschool programs were randomized to PAX GBG or treatment-as-usual. Independent observers conducted ratings of implementation fidelity and program quality across time; along with surveys of children's problem and prosocial behavior. Interaction effects were found using hierarchical linear models such that experimental programs evidencing higher implementation fidelity demonstrated better program quality than controls, (i.e., less harshness, increased appropriate structure, support, and engagement), as well as reduced child-reported hyperactivity and intent-to-treat effects on prosocial behavior. This study demonstrates that best practices fostered by PAX GBG and implemented with fidelity in afterschool result in higher quality contexts for positive youth development.

This article expands research on normative school transitions (NSTs) from elementary to middle school or middle to high school by examining the extent to which they disrupt structures of friendship networks. Social network analysis is used to quantify aspects of connectedness likely relevant to student experiences of social support. Data were drawn from 25 communities followed from sixth to ninth grades. Variability in timing of NSTs permitted multi-level longitudinal models to disentangle developmental effects from transition effects. Results indicated that friendship networks were most interconnected in smaller schools and among older students. Beyond these effects, transitions from a single feeder school to a single higher level school were not associated with changes in friendship patterns. Transitions from multiple feeder schools to a single higher level school were associated with diminished friendship stability, more loosely connected friendship networks, increased social distance between students, and friendship segregation between students who formerly attended different schools.
RESUMEN
Positive youth development (PYD) deserves more empirical attention, particularly among children of diverse racial-ethnic backgrounds. Given the need among families for monitoring and supervision during out-of-school time, community-based afterschool is a potentially promotive ecological setting. This study explores the quality of afterschool experiences upon PYD. This multimethod study includes over 500 elementary school children in Grades 2-5 (Mage = 8.80, SD = 1.12). The sample comprises of 49% White, 27% African American, 7% Latino, and 17% mixed race/others with 45% free/reduced lunch eligible children. In multilevel models, independently observed quality across time positively impacted competence, connection, caring for all youth, and cultural values for racial-ethnic minority youth. Afterschool fosters PYD, including sociocultural dimensions, when comprised of appropriately structured, supportive, and engaging interactions.

Many evaluation studies assess the direct effect of an intervention on individuals, but there is an increasing interest in clarifying how interventions can impact larger social settings. One process that can lead to these setting-level effects is diffusion, in which intervention effects spread from participants to non-participants. Diffusion may be particularly important when intervention participation rates are low, as they often are in universal family based prevention programs. We drew on socialization and diffusion theories to articulate how features of peer networks may promote the diffusion of intervention effects. Then, we tested the measurement properties of ten social network analytic (SNA) measures of diffusion potential. Data were from 42 networks (n = 5,784 students) involved in the PROSPER intervention trial. All families of sixth-grade students were invited to participate in a family based substance use prevention program, and 17 % of the families attended at least one session. We identified two dimensions of network structure--social integration and location of intervention participants in their peer network--that might promote diffusion. Analyses demonstrated that these SNA measures varied across networks and were distinct from traditional analytic measures that do not require social network analysis (i.e., participation rate, how representative participants are of the broader population). Importantly, several SNA measures and the global network index predicted diffusion over and above the effect of participation rate and representativeness. We conclude by recommending which SNA measures may be the most promising for studying how networks promote the diffusion of intervention effects and lead to setting-level effects.

Seeking to reduce problematic peer influence is a prominent theme of programs to prevent adolescent problem behavior. To support the refinement of this aspect of prevention programming, we examined peer influence and selection processes for three problem behaviors (delinquency, alcohol use, and smoking). We assessed not only the overall strengths of these peer processes, but also their consistency versus variability across settings. We used dynamic stochastic actor-based models to analyze five waves of friendship network data across sixth through ninth grades for a large sample of U.S. adolescents. Our sample included two successive grade cohorts of youth in 26 school districts participating in the PROSPER study, yielding 51 longitudinal social networks based on respondents' friendship nominations. For all three self-reported antisocial behaviors, we found evidence of both peer influence and selection processes tied to antisocial behavior. There was little reliable variance in these processes across the networks, suggesting that the statistical imprecision of the peer influence and selection estimates in previous studies likely accounts for inconsistencies in results. Adolescent friendship networks play a strong role in shaping problem behavior, but problem behaviors also inform friendship choices. In addition to preferring friends with similar levels of problem behavior, adolescents tend to choose friends who engage in problem behaviors, thus creating broader diffusion.

As the importance of afterschool hours for youth development is widely acknowledged, afterschool settings have recently received increasing attention as an important venue for youth interventions. A range of intervention programs have been in place, generally aiming at positive youth development through enhancing the quality of programs. A growing need has thus arisen for reliable and valid measures of afterschool quality. This study examined the extent to which the two observational tools, i.e., Caregiver Interaction Scales (CIS) and Promising Practices Rating Scales (PPRS), could serve as reliable and valid tools for assessing the various dimensions of afterschool setting quality. The study shows the potential promise of the instruments, on the one hand, and suggests future directions for improvement of measurement design and development of the field, on the other hand. In particular, our findings suggest the importance of addressing the effect of day-to-day fluctuations in observed afterschool quality.
RESUMEN
BACKGROUND: Meeting potential sexual/romantic partners for mutual pleasure is one of the main reasons young adults go to bars. However, not all sexual contacts are positive and consensual, and aggression related to sexual advances is a common experience. Sometimes such aggression is related to misperceptions in making and receiving sexual advances while other times aggression reflects intentional harassment or other sexually aggressive acts. This study uses objective observational research to assess quantitatively gender of initiators and targets and the extent that sexual aggression involves intentional aggression by the initiator, the nature of responses by targets, and the role of third parties and intoxication. METHODS: We analyzed 258 aggressive incidents involving sexual advances observed as part of a larger study on aggression in large capacity bars and clubs, using variables collected as part of the original research (gender, intoxication, intent) and variables coded from narrative descriptions (invasiveness, persistence, targets' responses, role of third parties). Hierarchical linear modeling analyses were used to account for nesting of incidents in evening and bars. RESULTS: Ninety percent of incidents involved male initiators and female targets, with almost all incidents involving intentional or probably intentional aggression. Targets mostly responded nonaggressively, usually using evasion. Staff rarely intervened; patron third parties intervened in 21% of incidents, usually to help the target but sometimes to encourage the initiator. initiators' level of invasiveness was related to intoxication of the targets, but not their own intoxication, suggesting intoxicated women were being targeted. CONCLUSIONS: Sexual aggression is a major problem in bars often reflecting intentional sexual invasiveness and unwanted persistence rather than misperceptions in sexual advances. Prevention needs to focus on addressing masculinity norms of male patrons and staff who support sexual aggression and better management of the highly sexualized and sexist environments of most bars.

OBJECTIVES: This study examines the effects of young adult transitions into marriage and cohabitation on criminal offending and substance use, and whether those effects changed since the 1970s as marriage rates declined and cohabitation rates rose dramatically. It also examines whether any beneficial effects of cohabitation depend on marriage intentions. METHODS: Using multi-cohort national panel data from Monitoring the Future (N = 15,875), the authors estimated fixed effects models relating within-person changes in marriage and cohabitation to changes in criminal offending and substance use. RESULTS: Marriage predicts lower levels of criminal offending and substance use, but the effects of cohabitation are limited to substance use outcomes and to engaged cohabiters. There are no cohort differences in the associations of marriage and cohabitation with criminal offending, and no consistent cohort differences in their associations with substance use. There is little evidence of differences in effects by gender or parenthood. CONCLUSIONS: Young adults are increasingly likely to enter romantic partnership statuses that do not appear as effective in reducing antisocial behavior. Although cohabitation itself does not reduce antisocial behavior, engagement might. Future research should examine the mechanisms behind these effects, and why non-marital partnerships reduce substance use and not crime.
RESUMEN
This study examines the effect of situational variables on whether third parties intervene in conflicts in barroom settings, and whether they are aggressive or not when they intervene. Based on research on bystander intervention in emergencies, we hypothesized that third parties would be most likely to become involved in incidents with features that convey greater danger of serious harm. The situational variables indicative of danger were severity of aggression, whether the aggression was one-sided or mutual, gender, and level of intoxication of the initial participants in the conflict. Analyses consist of cross-tabulations and three-level Hierarchical Logistic Models (with bar, evening, and incidents as levels) for 860 incidents of verbal and physical aggression from 503 nights of observation in 87 large bars and clubs in Toronto, Canada. Third party involvement was more likely during incidents in which: (1) the aggression was more severe; (2) the aggression was mutual (vs. one-sided) aggression; (3) only males (vs. mixed gender) were involved; and (4) participants were more intoxicated. These incident characteristics were stronger predictors of non-aggressive third party involvement than aggressive third party involvement. The findings suggest that third parties are indeed responding to the perceived danger of serious harm. Improving our knowledge about this aspect of aggressive incidents is valuable for developing prevention and intervention approaches designed to reduce aggression in bars and other locations.

Collective efficacy refers to a perceived sense of connectedness and willingness to intervene among youth, and is a potential aspect of positive youth development (Larson in Am Psychol 55:170-183, 2000; Lerner et al. in Child Dev 71:11-20, 2000; Sampson et al. in Science 277:918-924, 1997). Theoretically, those who feel connected to a group that is empowered to positively influence the behavior of their peers may demonstrate fewer problem behaviors. Few studies, however, have measured the impact of youth perceptions of collective efficacy. As a relatively new child-related research topic, there is much to be learned. One contribution to the foundation of this research agenda begins by evaluating the reliability and validity of a measure of collective efficacy with elementary children attending community-based afterschool programs. This paper describes the internal consistency reliability and various indicators of construct and concurrent validity of the Collective Efficacy Among Children Scale. The measure was found to have high internal consistency reliability. Construct validity was tested using exploratory factor analyses of collective efficacy including the dimensions of willingness to intervene and cohesion found in previous research (Sampson et al. in Science 277:918-924, 1997). Concurrent validity assessed relations between the scale and other measures in theoretically congruent ways. Using Hierarchical Linear Models to account for children's nestedness in after-school programs, connectedness was found to be more related to emotional adjustment, particularly children's prosocial attitudes (caring about others and sharing). Children's perception of the willingness of the group to intervene was found to be related to less problem behavior, (i.e. smoking tobacco, drinking alcohol, vandalism, and stealing). The implications suggest that future research should further explore children's collective efficacy, and ways to foster its development in youth-serving afterschool settings.

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships. We investigated change in the correlation between friends across 12 attributes covering demographics, orientations to key institutions (family, school, religion), and problem behavior, and we expected that the link between similarity and friendship would increase during adolescence for most attributes other than gender. We also predicted that the social ecological factors of school size and attribute variability would be associated with stronger correlations between friends and partially mediate developmental change. Data are from two grade cohorts of 27 small school districts, followed from sixth through 11th grades (N = 454 time-specific networks and over 65,000 person/waves of data; 84.2% White, 6.8% Hispanic/Latino, 3.2% African American, 1.3% Asian, .5% Native American, 3.9% other or multiple). The data analysis takes the form of a three-level random effects meta-analysis of network level correlations between friends (Moran's I). As expected, declining dominance of gender was offset by the emergence of moderate correlations across a broader profile of attributes. The ecological opportunity factors of grade cohort size and attribute variability significantly mediated these increases in correlations between friends, accounting for 23 to 73% of age-related change for 10 of the 11 attributes other than gender.

This paper introduces new longitudinal network data from the "Promoting School-Community-University Partnerships to Enhance Resilience" or "PROSPER" peers project. In 28 communities, grade-level sociometric friendship nominations were collected from two cohorts of middle school students as they moved from 6(th), to 9(th) grade. As an illustration and description of these longitudinal network data, this paper describes the school popularity structure, changes in popularity position, and suggests linkages between popularity trajectory and substance use. In the cross-section, we find that the network is consistent with a hierarchical social organization, but exhibits considerable relational change in both particular friends and position at the individual level. We find that both the base level of popularity and the variability of popularity trajectories effect substance use.
RESUMEN
A majority of school-based prevention programs target the modification of setting-level social dynamics, either explicitly (e.g., by changing schools' organizational, cultural or instructional systems that influence children's relationships), or implicitly (e.g., by altering behavioral norms designed to influence children's social affiliations and interactions). Yet, in outcome analyses of these programs, the rich and complicated set of peer network dynamics is often reduced to an aggregation of individual characteristics or assessed with methods that do not account for the interdependencies of network data. In this paper, we present concepts and analytic methods from the field of social network analysis and illustrate their great value to prevention science--both as a source of tools for refining program theories and as methods that enable more sophisticated and focused tests of intervention effects. An additional goal is to inform discussions of the broader implications of social network analysis for public health efforts.

Using data from the Monitoring the Future study, this paper presents historical trends in U.S. high school seniors' work values across 30 years (1976 to 2005. Adolescents across three decades highly valued most aspects of work examined. Recent cohorts showed declines in the importance of work, values for job security, and various potential intrinsic rewards of work. After increasing until 1990, adolescents remained stable in their values for extrinsic and materialistic aspects of work until 2005. The value of work that allows for leisure time has steadily increased. Stable level differences in work values emerged for adolescents by gender, race, parents' education, and college aspirations. Findings have implications for understanding the changing meaning of work for the future workforce.
RESUMEN
Despite the public health importance of alcohol-free social programs for college students, the majority of existing campus strategies have not been empirically evaluated. This study utilized repeated daily reports to examine the association between attendance at campus-led alcohol-free programming and alcohol use on specific days while controlling for individuals' typical rates of use. The current study assessed students' participation in the LateNight Penn State (LNPS) alcohol-free programming and amount of alcohol use at a daily level, in order to determine whether students consumed less alcohol on days they attended LNPS compared to weekend days they did not attend. First-year college students reported their daily social activity involvement and alcohol use via 14 consecutive daily web-based surveys. Multilevel regression analyses modeled variation in alcohol use on weekend days (N = 3,350) nested within people (N = 689 people, 51% women). Analyses focused on within-individual differences between nights attending and not attending LNPS, thereby controlling for stable individual differences, measured and unmeasured. Results indicated that students drank less on days they attended LNPS and on days they stayed in (rather than going to bars/parties, other campus events, or entertainment), both especially among women. These results suggest that alcohol-free social programs may be an effective strategy for decreasing alcohol use on days when students attend alcohol-free events rather than going to other events or gatherings.

Despite the public health burden of adolescent substance use, delinquency, and other problem behavior, few comprehensive models of disseminating evidence-based prevention programs to communities have demonstrated positive youth outcomes at a population level, capacity to maintain program fidelity, and sustainability. We examined whether the Communities That Care (CTC; Hawkins and Catalano 1992) model had a positive impact on risk/protective factors and academic and behavioral outcomes among adolescents in a quasi-experimental effectiveness study. We conducted a longitudinal study of CTC in Pennsylvania utilizing biannual surveillance data collected through anonymous in-school student surveys. We utilized multilevel models to examine CTC impact on change in risk/protective factors, grades, delinquency, and substance use over time. Youth in CTC communities demonstrated less growth in delinquency, but not substance use, than youth in non-CTC communities. Levels of risk factors increased more slowly, and protective factors and academic performance decreased more slowly, among CTC community grade-cohorts that were exposed to evidence-based, universal prevention programs than comparison grade cohorts. Community coalitions can affect adolescent risk and protective behaviors at a population level when evidence-based programs are utilized. CTC represents an effective model for disseminating such programs.

Most criminological theories predict an inverse relationship between employment and crime, but teenagers' involvement in paid work during the school year is positively correlated with delinquency and substance use. Whether the work-delinquency association is causal or spurious has long been debated. This study estimates the effect of paid work on juvenile delinquency using longitudinal data from the national Monitoring the Future project. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in juvenile delinquency and substance use to those in paid work and other explanatory variables. We also disentangle effects of actual employment from preferences for employment to provide insight about the likely role of time-varying selection factors tied to employment, delinquency, school engagement, and leisure activities. Whereas causal effects of employment would produce differences based on whether and how many hours respondents worked, we found significantly higher rates of crime and substance use among non-employed youth who preferred intensive versus moderate work. Our findings suggest the relationship between high-intensity work and delinquency results from preexisting factors that lead youth to desire varying levels of employment.
RESUMEN
Since the Environmental Movement began, adolescents' views have been largely ignored in studies of public opinion. The article presents a descriptive analysis of trends in the environmental attitudes, beliefs, and behaviors of high school seniors from 1976 to 2005 using data from the Monitoring the Future study. Across a range of indicators, environmental concerns of adolescents show increases during the early 1990s and declines across the remainder of the three decades. Declining trends in reports of personal responsibility for the environment, conservation behaviors, and the belief that resources are scarce are particularly noteworthy. Across all years, findings reveal that youth tended to assign responsibility for the environment to the government and consumers rather than accepting personal responsibility. Recent declines in environmental concerns for this nationally representative sample of youth signal the need for a renewed focus on young people's views and call for better environmental education and governmental leadership.
