Mechanisms of Influence on Youth Substance Use for a Social-Emotional and Character Development Program: A Theory-Based Approach.

The Theory of Triadic Influence (TTI) provides a comprehensive framework for understanding adolescent substance use. We examined mechanisms by which a TTI-guided social-emotional and character development program, (), influences adolescent substance use. Study data come from the -Chicago, longitudinal matched-pairs cluster-randomized control trial.

Relational victimization and peer affiliate prosocial behaviors in African American adolescents: Moderating effects of gender and antisocial behavior.

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.

Students as Prosocial Bystanders to Sexual Assault: Demographic Correlates of Intervention Norms, Intentions, and Missed Opportunities.

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.

A longitudinal study predicting adolescent tobacco, alcohol, and cannabis use by behavioral characteristics of close friends.

Few studies have examined in detail how specific behaviors of close friends put adolescents at risk for specific types of substance use. Using a prospective, longitudinal design, we examined how well the substance use of 248 young urban adolescents was predicted by perceptions of their 3 closest friends' problematic behaviors: (1) using substances, (2) offering substances, and (3) engaging with friends in risky behavior (substance use, illegal behavior, violent behavior, or high-risk sexual behavior). Longitudinal multivariate repeated measures models were tested to predict tobacco, alcohol, and cannabis use and perceived closeness was tested as a moderator of the effects of perceptions of problematic peer behavior.

School, Friends, and Substance Use: Gender Differences on the Influence of Attitudes Toward School and Close Friend Networks on Cannabis Involvement.

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.

Neighborhood disorder, peer network health, and substance use among young urban adolescents.

Background: The current study investigated the moderating effect of peer networks on neighborhood disorder's association with substance use in a sample of primarily African American urban adolescents.

Methods: A convenience sample of 248 adolescents was recruited from urban health care settings and followed for two years, assessing psychological, social, and geographic risk and protective characteristics. A subset of 106 substance using participants were used for the analyses.

A Mixed-Methods Approach Examining Illicit Prescription Stimulant Use: Findings From a Northern California University.

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.

Meeting the Challenges of Longitudinal Cluster-Based Trials in Schools: Lessons From the Chicago Trial of Positive Action.

We describe challenges in the 6-year longitudinal cluster randomized controlled trial (CRCT) of Positive Action (PA), a social-emotional and character development (SECD) program, conducted in 14 low-income, urban Chicago Public Schools. Challenges pertained to logistics of study planning (school recruitment, retention of schools during the trial, consent rates, assessment of student outcomes, and confidentiality), study design (randomization of a small number of schools), fidelity (implementation of PA and control condition activities), and evaluation (restricted range of outcomes, measurement invariance, statistical power, student mobility, and moderators of program effects). Strategies used to address the challenges within each of these areas are discussed.

Research design issues for evaluating complex multicomponent interventions in neighborhoods and communities.

Major advances in population health will not occur unless we translate existing knowledge into effective multicomponent interventions, implement and maintain these in communities, and develop rigorous translational research and evaluation methods to ensure continual improvement and sustainability. We discuss challenges and offer approaches to evaluation that are key for translational research stages 3 to 5 to advance optimized adoption, implementation, and maintenance of effective and replicable multicomponent strategies. The major challenges we discuss concern (a) multiple contexts of evaluation/research, (b) complexity of packages of interventions, and (c) phases of evaluation/research questions.

Effects of the Program on Indicators of Positive Youth Development Among Urban Youth.

This study evaluated effects of , a school-based social-emotional and character development (SECD) intervention, on indicators of positive youth development (PYD) among a sample of low-income, ethnic minority youth attending 14 urban schools. The study used a matched-pair, cluster-randomized controlled design at the school level. A multiple-measure self-report protocol assessed four key strengths and resources for PYD: self-concept, peer affiliations, ethics, and social skills.

Effects of a School-Based Social-Emotional and Character Development Program on Health Behaviors: A Matched-Pair, Cluster-Randomized Controlled Trial.

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.

Control, Norms, and Attitudes: Differences Between Students Who Do and Do Not Intervene as Bystanders to Sexual Assault.

Sexual assault is a major concern on the U.S. college campus.

Commentary on the 2015 SPR Standards of Evidence.

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.

The Illicit Use of Prescription Stimulants on College Campuses: A Theory-Guided Systematic Review.

The illicit use of prescription stimulants (IUPS) is a substance use behavior that remains prevalent on college campuses. As theory can guide research and practice, we provide a systematic review of the college-based IUPS epidemiological literature guided by one ecological framework, the theory of triadic influence (TTI). We aim to assess prevalence, elucidate the behavior's multietiological nature, and discuss prevention implications.

Teachers' Perceptions of School Organizational Climate as Predictors of Dosage and Quality of Implementation of a Social-Emotional and Character Development Program.

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).

Using structural equation modeling to understand prescription stimulant misuse: a test of the Theory of Triadic Influence.

Objective: To test a theory-driven model of health behavior to predict the illicit use of prescription stimulants (IUPS) among college students.

Participants: A probability sample of 554 students from one university located in California (response rate=90.52%).

Using social-emotional and character development to improve academic outcomes: a matched-pair, cluster-randomized controlled trial in low-income, urban schools.

Background: School-based social-emotional and character development (SECD) programs can influence not only SECD but also academic-related outcomes. This study evaluated the impact of one SECD program, Positive Action (PA), on educational outcomes among low-income, urban youth.

Methods: The longitudinal study used a matched-pair, cluster-randomized controlled design.

Effects of Positive Action on the emotional health of urban youth: a cluster-randomized trial.

Purpose: We examined the effects of Positive Action (PA), a school-based social-emotional learning and health promotion program, on the emotional health of predominately low-income and ethnic minority urban youth.

Methods: The study was a matched-pair, cluster-randomized controlled trial involving 14 Chicago public schools. Outcomes were assessed over a 6-year period of program implementation for a cohort of youth in each school, followed from grades 3 to 8.

Using the community readiness model as an approach to formative evaluation.

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.

Problem behavior and urban, low-income youth: a randomized controlled trial of positive action in Chicago.

Background: Youth problem behaviors remain a public health issue. Youth in low-income, urban areas are particularly at risk for engaging in aggressive, violent, and disruptive behaviors.

Purpose: To evaluate the effects of a school-based social-emotional learning and health promotion program on problem behaviors and related attitudes among low-income, urban youth.

Illicit use of prescription stimulants in a college student sample: a theory-guided analysis.

Background: The illicit use of prescription stimulants (IUPS) has emerged as a high-risk behavior of the 21st century college student. As the study of IUPS is relatively new, we aimed to understand (1) characteristics of IUPS (i.e.

Development and psychometric properties of a theory-guided prescription stimulant misuse questionnaire for college students.

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%).

Preventing negative behaviors among elementary-school students through enhancing students' social-emotional and character development.

Purpose: Examine the effects of a comprehensive, school-wide social-emotional and character development program using a positive youth development perspective. Specifically, we examined a mediation mechanism whereby positive academic-related behaviors mediated the intervention effects on substance use, violence, and sexual activity.

Design: Matched-pair, cluster-randomized, controlled design.

The critical role of nurturing environments for promoting human well-being.

The recent Institute of Medicine report on prevention (National Research Council & Institute of Medicine, 2009) noted the substantial interrelationship among mental, emotional, and behavioral disorders and pointed out that, to a great extent, these problems stem from a set of common conditions. However, despite the evidence, current research and practice continue to deal with the prevention of mental, emotional, and behavioral disorders as if they are unrelated and each stems from different conditions. This article proposes a framework that could accelerate progress in preventing these problems.
