There is evidence that risk for delinquency is elevated among girls with foster care histories, and one correlate of delinquency is affiliating with peers who engage in delinquent behavior. Althoug...

In this study, we tested the effects of cooperative learning on students’ prosocial behavior. Cooperative learning is a small-group instructional technique that establishes positive interdependence among students and, unlike most current school-based programs, does not mandate a formal curriculum. Given the emphasis in cooperative learning on peer reinforcement for positive and helpful behavior during learning activities, we hypothesized that cooperative learning would promote higher levels of p...

This paper examines the misalignment between modern human society and certain male phenotypes, a misalignment that has been highlighted and explored in great detail in the work of Tom Dishion. We begin by briefly enumerating the ongoing developmental difficulties of many boys and young men and how these difficulties affect them and those around them. We then suggest that the qualities that have been advantageous for men and their families in our earlier evolution but that are often no longer fun...

This article reviews the evidence regarding behavioral science approaches to the prevention of substance use disorders. Prevention science grew out of research on family and school-based interventions that were designed to treat common behavioral problems of children and adolescents. That research showed that the amelioration of problems such as aggressive behavior could prevent the development of later problems including substance use, depression, and academic failure. We begin by reviewing evi...

Abstract We tested a prevention approach aimed at reducing growth in alcohol use in middle school using four waves (2 years) of data from a cluster randomized trial (N = 15 middle schools, 1890 students, 47.1% female, 75.2% White). Our approach exposed students to a broad cross-section of peers through collaborative, group-based learning activities in school (i.e., cooperative learning). We hypothesized that the increased social contact created by cooperative learning would promote greater peer ...

Cross-sectional, longitudinal, and experimental studies have found a link between youth exposure to cigarette marketing and youth initiation of smoking. These decisive research findings led to regulations of cigarette marketing to youth—including no television or radio ads, prohibitions on the use of cartoons, bans on transit and billboard advertisements, and disallowing tobacco brand sponsorships of sporting events or concerts. Similar products that may cause more harm than benefits include alc...

abstractReward & Reminder has been a component of community-based preventive efforts against sales of substances (e.g., tobacco) to youths. To date, there has not been a randomized trial of Reward & Reminder as a stand-alone prevention program targeting youth access to alcohol. In this study, we address that gap. Data were collected as part of a randomized trial of a school- and community-based prevention program. Our analysis included 23 vendors in control communities and 33 vendors in interven...
