Reducing adolescents' growth in substance use and delinquency: randomized trial effects of a parent-training prevention intervention.

The relationship between growth in adolescent substance use and delinquency was examined in a longitudinal, randomized controlled study of the Preparing for the Drug Free Years Program (PDFY), a universal family-focused prevention intervention. Latent growth curve modeling was used to analyze 5 waves of data collected from 429 rural adolescents. Results showed that adolescents assigned to the PDFY intervention condition had a slower rate of linear increase over time in both substance use and delinquency compared with adolescents assigned to the control condition. Moreover, pretest level of delinquency was a reliable, positive predictor of growth in substance use, whereas pretest level of substance use did not predict growth in delinquency.

Effects of the Seattle social development project on sexual behavior, pregnancy, birth, and sexually transmitted disease outcomes by age 21 years.

OBJECTIVE: To examine the long-term effects of the full Seattle Social Development Project intervention on sexual behavior and associated outcomes assessed at age 21 years. DESIGN: Nonrandomized controlled trial with long-term follow-up. SETTING: Public elementary schools serving children from high-crime areas in Seattle, Wash. PARTICIPANTS: Ninety-three percent of the fifth-grade students enrolled in either the full-intervention or control group were successfully interviewed at age 21 years (n = 144 [full intervention] and n = 205 [control]). INTERVENTIONS: In-service teacher training, parenting classes, and social competence training for children. MAIN OUTCOME MEASURES: Self-report measures of all outcomes. RESULTS: The full-intervention group reported significantly fewer sexual partners and experienced a marginally reduced risk for initiating intercourse by age 21 years as compared with the control group. Among females, treatment group status was associated with a significantly reduced likelihood of both becoming pregnant and experiencing a birth by age 21 years. Among single individuals, a significantly increased probability of condom use during last intercourse was predicted by full-intervention group membership; a significant ethnic group x intervention group interaction indicated that after controlling for socioeconomic status, single African Americans were especially responsive to the intervention in terms of this outcome. Finally, a significant treatment x ethnic group interaction indicated that among African Americans, being in the full-intervention group predicted a reduced probability of contracting a sexually transmitted disease by age 21 years. CONCLUSION: A theory-based social development program that promotes academic success, social competence, and bonding to school during the elementary grades can prevent risky sexual practices and adverse health consequences in early adulthood.

Developmental relationships between adolescent substance use and risky sexual behavior in young adulthood.

PURPOSE: To examine the developmental relationship between adolescent substance use and risky sexual behavior in young adulthood. A gender-balanced, ethnically diverse urban sample of 808 children in Seattle was surveyed at age 10 years in 1985 and followed prospectively to age 21 years in 1996. Semiparametric group-based modeling was used to determine trajectory groups of binge-drinking, cigarette smoking, marijuana use, and the use of other illicit drugs. Negative binomial regressions and logistic regressions were used to examine whether these trajectory groups predicted the number of sex partners and condom use at age 21 years. Specific forms of adolescent substance use significantly predicted risky sexual behavior at age 21 years, after other substance use and early measures of sexual behavior were controlled. Early binge-drinkers had significantly more sex partners than nonbinge-drinkers. Late onset binge-drinkers and marijuana users had significantly more sex partners and were less likely to use condoms consistently than those who did not binge drink or use marijuana. Experimenters in cigarette smoking, who did not escalate smoking, were more likely to use condoms consistently than nonsmokers. In contrast, the use of other illicit drugs in adolescence did not predict risky sexual behavior at age 21 years. The effects of adolescent substance use on risky sexual behavior at age 21 years differed for youths with developmentally different substance use trajectories in this urban sample disproportionately drawn from high crime neighborhoods. To prevent risky sexual behavior among young adults, attention should be paid to binge-drinking and marijuana use during adolescence.

Prevention science and positive youth development: competitive or cooperative frameworks?

PURPOSE: To examine the convergence in the critiques and recommendations for the future of programs to promote healthy development and prevent problem behaviors among children and adolescents. METHODS: A review of literature captures two streams of thought, those promoting positive youth development approaches to youth programming and those promoting prevention science approaches to youth programming. RESULTS: Results suggest that advocates of positive youth development and prevention science have similar critiques of single-problem-focused prevention programs in the 1980s and early 1990s, and have similar recommendations for the future of youth programming. Further, review of data on youth development suggests that it is important to focus on risk and protection in preventing adolescent problems as well as in promoting positive youth development. CONCLUSIONS: These results suggest that both youth development and prevention science approaches have grown from similar roots and make similar recommendations for the future of youth programming. Further, data on precursors suggest that focusing on promoting protection and reducing risk is likely to prevent problems and promote positive youth development. Yet advocates of these approaches often are at odds, suggesting that the approaches provide different paradigmatic approaches to youth programming. We conclude that cooperation between these two approaches would further progress in the field of youth programming.

A developmental analysis of sociodemographic, family, and peer effects on adolescent illicit drug initiation.

OBJECTIVE: To examine the effects of sociodemographic, family, and peer predictors on the developmental patterns of illicit drug initiation from ages 12 to 21 years. METHOD: A gender-balanced, ethnically diverse urban sample of 808 children in Seattle was surveyed at age 10 in 1985 and followed prospectively to age 21 in 1996. Discrete-time survival analysis was used to assess the effects of sociodemographic, family, and peer factors on the risk of initiation. RESULTS: The risk for initiating illicit drug use increased steadily from ages 12 to 21. High family conflict, low family bonding, and high peers' antisocial activities predicted higher risk of initiation across this developmental period. The effect of family bonding began to decline after age 18, while the effect of peers' antisocial activities began to increase after age 15. Few gender and ethnic differences were found. CONCLUSIONS: Prevention programs need to include family and peer factors as important targets. Parents should create a warm and supportive family environment with appropriate supervision and control throughout adolescence. Association with antisocial peers should be reduced, especially in high school. Interventions addressing these family and peer factors should have beneficial effects across gender and ethnic groups.

Measuring risk and protective factors for substance use, delinquency, and other adolescent problem behaviors. The Communities That Care Youth Survey.

Risk and protective factors predictive of adolescent problem behaviors such as substance abuse and delinquency are promising targets for preventive intervention. Community planners should assess and target risk and protective factors when designing prevention programs. This study describes the development, reliability, and validity of a self-report survey instrument for adolescents ages 11 to 18 that measures an array of risk and protective factors across multiple ecological domains as well as adolescent problem behaviors. The instrument can be used to assess the epidemiology of risk and protection in youth populations and to prioritize specific risk and protective factors in specific populations as targets for preventive intervention.

Promoting science-based prevention in communities.

In the past decade, prevention science has emerged as a discipline built on the integration of life course development research, community epidemiology, and preventive intervention trials [Am. Psychol. 48 (1993) 1013; Am. J. Community Psychol. 27 (1999) 463; Kellam, S. G., & Rebok, G. W. (1992). Building developmental and etiological theory through epidemiologically based preventive intervention trials. In J. McCord & R. E. Tremblay (Eds.), Preventing antisocial behavior: interventions from birth through adolescence (pp. 162-195). New York: Guilford Press.]. Prevention science is based on the premise that empirically verifiable precursors (risk and protective factors) predict the likelihood of undesired health outcomes including substance abuse and dependence. Prevention science postulates that negative health outcomes like alcohol abuse and dependence can be prevented by reducing or eliminating risk factors and enhancing protective factors in individuals and their environments during the course of development. A growing number of interventions have been found to be effective in preventing adolescent tobacco, alcohol, and other drug abuse, delinquency, violence, and related health risk behaviors by reducing risk and enhancing protection. During the same decade, comprehensive community-based interventions to prevent adolescent health and behavior problems have been widely implemented in the U.S. with federal and foundation support. Despite the advances in the science base for effective preventive interventions and the investments in community-wide preventive interventions, many communities continue to invest in prevention strategies with limited evidence of effectiveness [Am. J. Public Health 84 (1994) 1394; J. Res. Crime Delinq. 39 (2002) 3; J. Community Psychol. 28 (2000) 237; J. Community Psychol. 28 (2000) 237; J. Consult. Clin. Psychol. 67 (1999) 590; Eval. Program Plann. 20 (1997) 367.]. Translating prevention science into community prevention systems has emerged as a priority for prevention research [J. Community Psychol. 28 (2000) 363; J. Appl. Behav. Anal. 28 (1995) 479.]. The Communities That Care (CTC) prevention operating system is a field-tested strategy for activating communities to use prevention science to plan and implement community prevention systems. CTC provides tools that assist communities to use local data on risk and protective factors to identify elevated risks and depressed protective factors in geographic areas where levels of risk are high and levels of protection are low and then to implement tested, effective preventive interventions that reduce the identified risks and enhance protection in these [Developmental Research and Programs. (1997). Communities That Care: a comprehensive prevention program. Seattle, WA: Author; Developmental Research and Programs. (2000a). Communities That Care: a comprehensive prevention program. Seattle: Author; Hawkins, J. D., Catalano, R. F., et al. (1992). Communities That Care: action for drug abuse prevention (1st ed.). A joint publication of the Jossey-Bass social and behavioral science series and the Jossey-Bass education series. San Francisco: Jossey-Bass]. The CTC system is widely implemented, and process evaluations of CTC suggest that it can assist communities to develop more effective prevention systems. This paper describes the background and use of the CTC operating system and results of evaluations of implementation of the system.
