ABSTRACT
Background: The Theory of Triadic Influence (TTI) provides a comprehensive framework for understanding adolescent substance use. Objectives: We examined mechanisms by which a TTI-guided social-emotional and character development program, Positive Action (PA), influences adolescent substance use. Study data come from the PA-Chicago, longitudinal matched-pairs cluster-randomized control trial. A diverse, dynamic cohort of approximately 1,200 students from 14 low-performing schools were assessed at eight points of time, between grades 3-8, across a six-year period. Students completed scales related to substance use, self-control, deviant peer affiliation, and school attachment, adapted from the Risk Behavior Survey, Social-Emotional and Character Development Scale, Conventional Friends Scale, and People in My Life Scale. After testing the overall effect of PA on substance use, we used latent growth modeling to assess whether effects on each outcome were mediated by longitudinal changes in three composite measures aligning with the TTIs three streams. Results: Students in PA schools reported fewer experiences with drinking, getting drunk, and overall substance use. In the multiple mediator models, significant indirect effects of PA on substance use via changes in self-control were evident. Conclusions/Importance: Findings are consistent with theory and past research suggesting the influence of self-control on youth substance use. Future studies should include implementation in different settings and additional theory-based measures.Trial RegistrationThis trial is registered at ClinicalTrials.gov NCT01025674.

INTRODUCTION: Experiencing relational victimization (e.g., peer exclusion, untrue rumors) during adolescence can have negative social-emotional consequences, including increased antisocial behavior and substance use. The negative impact of relational victimization may be lessened by spending time with supportive, prosocial peers. METHODS: This study examined the concurrent and predictive associations between relational victimization and peer affiliates' prosocial behaviors in 244 predominately African American adolescents (ages 13-14) living in U.S. urban neighborhoods. Questionnaires were collected every six months for two years. Overt victimization was controlled for in the analysis and the moderation of gender and antisocial behaviors were tested. RESULTS: Peer affiliates' prosocial behavior was stable across the two years. Relational victimization was not associated with peers' prosocial behavior at baseline or across time. Gender did not moderate the association between relational victimization and peers' prosocial behavior. Moderating effects were found for antisocial behavior; relational victimization was positively associated with peer affiliates' prosocial behavior but only for adolescents who were low on antisocial behavior at baseline. CONCLUSIONS: For African American youth, efforts to reduce relational aggression and increase peer support in prosocial activities prior to adolescence may be useful for preventing social-emotional problems.

Prior research has yet to elucidate how constellations of protective factors in childhood and prevention efforts simultaneously may influence youth involvement in problem behaviors across different points in development. The current study examines how latent classes of social and emotional learning (SEL) skills, parent-child relationships, and peer influences in third grade and receipt of an ongoing SEL intervention predict substance use and violence in fifth and eighth grade. The urban, predominantly low-income, sample (N = 1,169) was nested in 14 schools that were randomly assigned to the Positive Action program or business-as-usual. Membership in a latent class reflecting protective childhood factors predicted less substance use and violence in fifth grade; however, the SEL program predicted less substance use and violence in eighth grade. Findings generally support that SEL interventions can successfully target and boost developmentally appropriate positive behaviors and can prevail over initial risk factors with enough time and exposure.
ABSTRACT
Sensation seeking has been identified as a significant risk factor for adolescent alcohol use. Little is known, however, about the process by which sensation seeking impacts heavy alcohol use. The current study used structural equation modeling (SEM) to examine the relationships among sensation seeking, age of drinking initiation, and heavy alcohol use in a sample of high school seniors (N = 221). Results supporting age of drinking initiation as a mediator of the relationship between sensation seeking and heavy alcohol use. Implications include providing personality-targeted prevention to adolescents who display sensation seeking traits to delay drinking initiation among these students.
ABSTRACT
The school environment is extremely salient in young adolescents' lives. Adolescents who have unfavorable attitudes toward school and teachers are at elevated risk for dropping out of school and engaging in behavioral health risks. Peer network health-a summation of the positive and negative behaviors in which one's close friend group engages-may be one way by which attitudes toward school exert influence on youth substance use. Utilizing a sample of 248 primarily African-American young urban adolescents, we tested a moderated mediation model to determine if the indirect effect of attitude to school on cannabis involvement through peer network health was conditioned on gender. Attitude toward school measured at baseline was the predictor (X), peer network health measured at 6 months was the mediator (M), cannabis involvement (including use, offers to use, and refusals to use) measured at 24 months was the outcome (Y), and gender was the moderator (W). Results indicated that negative attitudes toward school were indirectly associated with increased cannabis involvement through peer network health. This relationship was not moderated by gender. Adolescents in our sample with negative attitudes toward school were more likely to receive more offers to use cannabis and to use cannabis more frequently through the perceived health behaviors of their close friends. Implications from these results point to opportunities to leverage the dynamic associations among school experiences, friends, and cannabis involvement, such as offers and use.

Behavioral trajectories during middle childhood are predictive of consequential outcomes later in life (e.g., substance abuse, violence). Social and emotional learning (SEL) programs are designed to promote trajectories that reflect both growth in positive behaviors and inhibited development of negative behaviors. The current study used growth mixture models to examine effects of the Positive Action (PA) program on behavioral trajectories of social-emotional and character development (SECD) and misconduct using data from a cluster-randomized trial that involved 14 schools and a sample of predominately low-income, urban youth followed from 3rd through 8th grade. For SECD, findings indicated that PA was similarly effective at improving trajectories within latent classes characterized as "high/declining" and "low/stable". Favorable program effects were likewise evident to a comparable degree for misconduct across observed latent classes that reflected "low/rising" and "high/rising" trajectories. These findings suggest that PA and perhaps other school-based universal SEL programs have the potential to yield comparable benefits across subgroups of youth with differing trajectories of positive and negative behaviors, making them promising strategies for achieving the intended goal of school-wide improvements in student outcomes.

Preventing the illicit use of prescription stimulants, a particularly high-risk form of substance use, requires approaches that utilize theory-guided research. We examined this behavior within the context of a random sample of 554 undergraduate students attending a university in northern California. Approximately 17% of students self-reported engaging in this behavior during college; frequency of misuse per academic term ranged from less than once to 40 or more times. Although most misusers reported oral ingestion, a small proportion reported snorting and smoking the drug. The majority of misusers reported receiving the drug at no cost, and the primary source of the drug was friends. Misusers were motivated by both academic (e.g., to improve focus) and non-academic (e.g., to experiment) reasons. Our thematic analyses of an open-end question revealed that students abstaining from illicit use of prescription stimulants did so primarily for reasons related to health risks, ethics, and adherence regulations. Results from adjusted logistic regression analyses showed that correlates of the behavior were intrapersonal, interpersonal, and environmental in nature. We conclude that characteristics of misuse are a cause for concern, and correlates of the behavior are multifaceted. These findings, in addition to insights provided by students who choose not to engage in this behavior, suggest that a number of prevention approaches are plausible, such as a social norms campaign that simultaneously corrects exaggerated beliefs about prevalence while also illustrating why abstainers, in their own words, choose to abstain.

There is considerable research that suggests that school-based social-emotional programs can foster improved mental health and reduce problem behaviors for participating youth; in contrast, much less is known about the impact of these programs on physical health, even though some of these programs also include at least limited direct attention to promoting physical health behaviors. We examined the effects of one such program, Positive Action (PA), on physical health behaviors and body mass index (BMI), and tested for mediation of program effects through a measure of social-emotional and character development (SECD). Participating schools in the matched-pair, cluster-randomized trial were 14 low-performing K-8 Chicago Public Schools. We followed a cohort of students in each school from grades 3 to 8 (eight waves of data collection; 1170 total students). Student self-reports of health behaviors served as the basis for measures of healthy eating and exercise, unhealthy eating, personal hygiene, consistent bedtime, and SECD. We collected height and weight measurements at endpoint to calculate age- and gender-adjusted BMI z-scores. Longitudinal multilevel modeling analyses revealed evidence of favorable program effects on personal hygiene [effect size (ES) = 0.48], healthy eating and exercise (ES = 0.21), and unhealthy eating (ES = -0.19); in addition, BMI z-scores were lower among students in PA schools at endpoint (ES = -0.21). Program effects were not moderated by either gender or student mobility. Longitudinal structural equation modeling demonstrated mediation through SECD for healthy eating and exercise, unhealthy eating, and personal hygiene. Findings suggest that a SECD program without a primary focus on health behavior promotion can have a modest impact on outcomes in this domain during the childhood to adolescence transition.

We comment on the 2015 Society for Prevention Research standards of evidence document, summarizing major changes from the previous 2005 Standards, and point to ways in which the Standards could be further improved. We endorse important new standards, such as those on testing the causal theory and mechanisms of the intervention, improved trial reporting standards, and added attention to scale-up research and cost analyses. Despite discussion of replication in the new Standards, we are concerned about the lack of stand-alone replication standards, and the deletion of an explicit requirement for replication before an intervention is considered efficacious. Finally, we are deeply concerned about the lack of attention to the unit or level of aggregation of the intervention target. It is a major conceptual oversight. The unit targeted by an intervention (whether a cell, person, organization, community, state, nation) is a fundamental feature shaping intervention theory, research design, data collection, analyses, effect sizes, diffusion possibilities and patterns, and scale-up issues. Future Standards updates should eliminate the implicit assumption in the current text that effective preventive interventions inherently target individual persons.

Organizational climate has been proposed as a factor that might influence a school's readiness to successfully implement school-wide prevention programs. The aim of this study was to evaluate the influence of teachers' perceptions of three dimensions of school organizational climate on the dosage and quality of teacher implementation of Positive Action, a social-emotional and character development (SECD) program. The dimensions measured were teachers' perceptions of (a) the school's openness to innovation, (b) the extent to which schools utilize participatory decision-making practices, and (c) the existence of supportive relationships among teachers (teacher-teacher affiliation). Data from 46 teachers in seven schools enrolled in the treatment arm of a longitudinal, cluster-randomized, controlled trial were analyzed. Teacher perceptions of a school's tendency to be innovative was associated with a greater number of lessons taught and self-reported quality of delivery, and teacher-teacher affiliation was associated with a higher use of supplementary activities. The findings suggest that perceptions of a school's organizational climate impact teachers' implementation of SECD programs and have implications for school administrators and technical assistance providers as they work to implement and sustain prevention programs in schools.

BACKGROUND: Researchers regularly must decide what information is necessary to understand school climate and how to include climate in a study. For example, which factors and/or scales should be used, is using just 1 scale for school climate sufficient, and to what extent does the selection of a single scale influence the research findings? AIMS: Understanding what factors to consider and which available scales to review will assist those interested in measuring school climate. METHODS: This study explores 8 validated scales related to school climate. Data used are from a previous study (Social and Character Development cooperative agreement funded by IES #R305L030072 and #R305A080253) that looked at Positive Action, a social emotional and character development program for elementary-, middle-, and high-school students. RESULTS AND CONCLUSION: Scale correlations and factor analyses show how these scales work together to measure overall middle school climate.

A theory-guided instrument for examining prescription stimulant misuse in the college population was developed and its psychometric properties were evaluated from 2011 to 2012 at one Pacific Northwest (United States) university. Study methods included instrument development, assessment by five health and measurement professionals, group interviews with six college students, a test-retest pilot study, and a paper-based, in-classroom, campus study using one-stage cluster sampling (N = 520 students, 20 classrooms, eligible student response rate = 96.30%). The instrument demonstrated reliability (i.e., internal consistency and stability) and validity (i.e., face, content, and predictive). Limitations and implications are discussed.

Most youth cessation treatment research consists of efficacy studies in which treatments are evaluated under optimal conditions of delivery. Less is known about the effectiveness of youth cessation treatments delivered in real-world, community based settings. A national sample of 41 community-based youth cessation programs participated in a longitudinal evaluation to identify site, program, and participant characteristics associated with successful cessation. Validated quit rates were comparable to those in randomized controlled trials; 7-day abstinence at the end of program averaged 14% and 30-day abstinence at 12 months averaged 12%. Multivariate GEE models explored predictors of smoking cessation at the end of the programs and at 12 months. Results showed correlates of both short- and long-term cessation. Findings point to the importance of both individual and community-level variables, including motivation, opportunities for and encouragement to engage in activities outside of academics, having youth participate in treatment before they become highly dependent smokers, and community norms and ordinances that discourage youth purchase, use and possession of tobacco. Providing evidence-based treatment to youth in community-based settings results in successful cessation.

This article presents an adapted version of an established model for assessing community readiness along with an illustrative case example from the evaluation of Positive Action, a school-based social and character development intervention, implemented as part of a randomized controlled trial in Chicago Public Schools from 2004 through 2010. Community readiness is an emerging assessment approach that can be used to gauge the level of understanding, desire, and ownership that community members have regarding a community problem and/or intervention. This approach is useful in engaging the community and leveraging particular aspects of readiness that the community may exhibit in order to maximize an intervention's successful implementation. The article concludes with a discussion of ways in which a community readiness model may be useful in health promotion practice, both in schools and in other community settings.

Person mobility is an inescapable fact of life for most cluster-randomized (e.g., schools, hospitals, clinic, cities, state) cohort prevention trials. Mobility rates are an important substantive consideration in estimating the effects of an intervention. In cluster-randomized trials, mobility rates are often correlated with ethnicity, poverty and other variables associated with disparity. This raises the possibility that estimated intervention effects may generalize to only the least mobile segments of a population and, thus, create a threat to external validity. Such mobility can also create threats to the internal validity of conclusions from randomized trials. Researchers must decide how to deal with persons who leave study clusters during a trial (dropouts), persons and clusters that do not comply with an assigned intervention, and persons who enter clusters during a trial (late entrants), in addition to the persons who remain for the duration of a trial (stayers). Statistical techniques alone cannot solve the key issues of internal and external validity raised by the phenomenon of person mobility. This commentary presents a systematic, Campbellian-type analysis of person mobility in cluster-randomized cohort prevention trials. It describes four approaches for dealing with dropouts, late entrants and stayers with respect to data collection, analysis and generalizability. The questions at issue are: 1) From whom should data be collected at each wave of data collection? 2) Which cases should be included in the analyses of an intervention effect? and 3) To what populations can trial results be generalized? The conclusions lead to recommendations for the design and analysis of future cluster-randomized cohort prevention trials.

The effects of a school-based social-emotional and character development program, Positive Action, on the developmental trajectory of social-emotional and character-related behaviors was evaluated using data from three school-based randomized trials in elementary schools. Results come from 1) 4 years of data from students in 20 Hawai'i schools, 2) 3 years of data from students in 14 schools in Chicago and 3) 3 years of data from students in 8 schools in a southeastern state. Random intercept, multilevel, growth-curve analyses showed that students in both control and Positive Action schools exhibited a general decline in the number of positive behaviors associated with social-emotional and character development that were endorsed. However, the Positive Action intervention significantly reduced these declines in all three trials. Taken together, these analyses 1) give insight into the normative trajectory of behaviors associated with social-emotional and character development and 2) provide evidence for the effectiveness of Positive Action in helping children maintain a relatively beneficial developmental trajectory.

Replication research is essential for the advancement of any scientific field. In this paper, we argue that prevention science will be better positioned to help improve public health if (a) more replications are conducted; (b) those replications are systematic, thoughtful, and conducted with full knowledge of the trials that have preceded them; and (c) state-of-the art techniques are used to summarize the body of evidence on the effects of the interventions. Under real-world demands it is often not feasible to wait for multiple replications to accumulate before making decisions about intervention adoption. To help individuals and agencies make better decisions about intervention utility, we outline strategies that can be used to help understand the likely direction, size, and range of intervention effects as suggested by the current knowledge base. We also suggest structural changes that could increase the amount and quality of replication research, such as the provision of incentives and a more vigorous pursuit of prospective research registers. Finally, we discuss methods for integrating replications into the roll-out of a program and suggest that strong partnerships with local decision makers are a key component of success in replication research. Our hope is that this paper can highlight the importance of replication and stimulate more discussion of the important elements of the replication process. We are confident that, armed with more and better replications and state-of-the-art review methods, prevention science will be in a better position to positively impact public health.

Sexual assault is a major public health issue. Bystander engagement programs are becoming widely used to combat sexual assault on college campuses. The purpose of this study was to examine students' intervention norms, intentions, opportunities, and behaviors as bystanders to sexual assault. Undergraduate students (N = 779) completed the Sexual Assault Bystander Behavior Questionnaire in the fall of 2014. The t tests revealed differences in students' intervention norms, intentions, opportunities, and missed opportunities based on sex, race/ethnicity, athletic participation, and fraternity/sorority membership. The findings support the use of additional measures to assess bystander behavior and to identify student subpopulations that may benefit from programs aimed at increasing prosocial intervention.

Despite the escalation of alcohol use through high school, the majority of research on school-based alcohol interventions has been conducted with junior high students or first and second year high school students. Preliminary research indicates a brief, web-based personalized feedback intervention developed for college students (eCHECKUP TO GO) may be a promising program for high school seniors. Although these studies demonstrate positive intervention effects, there is some evidence for greater program efficacy for females in this age group. The current study investigates sex differences in program acceptability of the eCHECKUP TO GO and its relationship to short-term alcohol outcomes among high school seniors (N = 135). Overall, the majority of students reported they found the program to be acceptable (i.e., user-friendly and useful). However, contrary to our hypothesis, results indicated that male students reported significantly higher perceptions of program acceptability than females. Although, we did not find sex differences in alcohol outcomes, program user-friendliness was related to reductions in alcohol use for males. Results of this study add to the literature supporting the eCHECKUP TO GO for high school seniors and highlight the importance of program user-friendliness for males. Implications for implementing the program as a school-based intervention are discussed.
ABSTRACT
OBJECTIVE: The purpose of this randomized controlled study was to examine sex as a moderator of the efficacy of a brief, web-based personalized feedback intervention (eCHECKUP TO GO) on decreasing cognitive risk factors for alcohol use, increasing protective behavioral strategies, and reducing alcohol use among high school seniors. METHOD: Participants (n = 311) were high school seniors randomized by class period to the eCHECKUP TO GO intervention or assessment-only control group. Participants completed online surveys at baseline and 30-day follow-up (91.0%; n = 283). RESULTS: Students in the intervention group reported a significant reduction in normative perceptions of peer drinking, positive alcohol expectancies, and alcohol use relative to those in the control group. Intervention effects for perceptions of frequency of peer drunkenness and frequency of alcohol use were moderated by sex, with results favoring females. In contrast, we did not find evidence for sex as a moderator of intervention effects for normative perceptions of peer drinking frequency, sex-specific perceptions of peer heavy episodic drinking, positive alcohol expectancies, or peak drinking quantity. Further, we did not find significant intervention or moderator effects for protective behavioral strategies. CONCLUSIONS: Results of this study extend the literature by demonstrating the efficacy of the eCHECKUP TO GO for both males and females on reducing cognitive risk factors and alcohol use, although results were significant for a broader range of variables for females. Results also indicate that program content regarding normative feedback and protective behavioral strategies may need modification to be more effective for this age group.
