Drug abuse prevention programs conducted during junior high school can produce meaningful and durable reductions in tobacco, alcohol, and marijuana use if they (1) teach a combination of social resistance skills and general life skills, (2) are properly implemented, and (3) include at least 2 years of booster sessions.

This study examined how parenting factors were associated with adolescent problem behaviors among urban minority youth and to what extent these relationships were moderated by family structure and gender. Sixth-grade students (N = 228) reported how often they use alcohol, smoke cigarettes, or engage in aggressive or delinquent behaviors; a parent or guardian reported their monitoring and other parenting practices. Findings indicated that boys and those from singleparent families engaged in the highest rates of problem behavior. More parental monitoring was associated with less delinquency overall, as well as less drinking in boys only. Eating family dinners together was associated with less aggression overall, as well as less delinquency in youth from single-parent families and in girls. Unsupervised time at home alone was associated with more smoking for girls only. Implications for prevention interventions are discussed. Research and theory on the etiology of problem behavior in childhood and adolescence often focus on the role of the family in the development of antisocial behavior (

Students (N = 4,466) attending 56 schools in New York State were involved in a 3-year study testing the effectiveness of a cognitive-behavioral approach to substance abuse prevention. In a randomized block design, schools were assigned to receive (a) the prevention program with formal provider training and implementation feedback, (b) the prevention program with videotaped provider training and no feedback, or (c) no treatment. After pretest equivalence and comparability of conditions with respect to attrition were established, students who received at least 60% of the prevention program (N = 3,684) were included in analyses of program effectiveness. Significant prevention effects were found for cigarette smoking, marijuana use, and immoderate alcohol use. Prevention effects were also found for normative expectations and knowledge concerning substance use, interpersonal skills, and communication skills.

Synopsis Substantial progress has been made in developing prevention programs for adolescent drug abuse. The most effective interventions target salient risk and protective factors at the individual, family, and/or community levels and are guided by relevant psychosocial theories regarding the etiology of substance use and abuse. This article reviews the epidemiology, etiologic risk and protective factors, and evidence-based approaches that have been found to be most effective in preventing adolescent substance use and abuse. Exemplary school and family-based prevention programs for universal (everyone in population), selected (members of at-risk groups), and indicated (at-risk individuals) target populations are reviewed, along with model community-based prevention approaches. Challenges remain in widely disseminating evidence-based prevention programs into schools, families, and communities.

Substance use and abuse are important public health problems in the USA and throughout the world. In many developed countries, the initial stages of substance use typically include experimentation with alcohol, tobacco, or marijuana with one's peer group during adolescence. While there have been gradual decreases in the use of these substances in recent years among youth in the USA and other countries, increases have been observed in the use and misuse of other substances, such as the misuse of prescription drugs and over-the-counter cough medications in the USA. From a developmental perspective, data shows that rates of alcohol, tobacco, marijuana, and other illicit drug use typically escalate during adolescence and peak during young adulthood, corresponding with the increased freedom and independence of this time of life. Substance use decreases for most young people as they take on adult responsibilities, although a proportion will continue or increase their use and develop substance use problems. Given what we know about the onset and progression of substance use, implementing preventive interventions during early adolescence is critical. Most drug prevention or education programmes take place in school settings. A variety of theory-based school-based drug prevention programmes have been developed and tested. The most effective programmes are delivered interactively and teach skills to help young people refuse drug offers, resist pro-drug influences, correct misperceptions that drug use is normative, and enhance social and personal competence skills. A key challenge is to identify mechanisms for the wide dissemination of evidence-based drug preventive interventions and ways to train providers to implement programmes effectively and thoroughly.

Abstract:Violence is an important public health problem among adolescents in the United States. Substance use and violence tend to co-occur among adolescents and appear to have similar etiologies. The present study examined the extent to which a comprehensive prevention approach targeting an array of individual-level risk and protective factors and previously found effective in preventing tobacco, alcohol, and illicit drug use is capable of decreasing violence and delinquency. Schools (N=41) were randomly assigned to intervention and control conditions. Participants in the 20 intervention schools received the Life Skills Training prevention program including material focusing on violence and the media, anger management, and conflict resolution skills. Survey data were collected from 4,858 sixth grade students prior to the intervention and three months later after the intervention. Findings showed significant reductions in violence and delinquency for intervention participants relative to controls. Stronger prevention effects were found for students who received at least half of the preventive intervention. These effects include less verbal and physical aggression, fighting, and delinquency. The results of this study indicate that a school-based prevention approach previously found to prevent tobacco, alcohol, and illicit drug use can also prevent violence and delinquency.
