..Results support the community-university partnership model for recruitment that was implemented in the study...

..The observed pattern of results likely reflects a combination of predispositions of the higher-risk subsample, the timing of the interventions, and baseline differences between experimental conditions favoring the control group...

..This is a supplemental report on tests of the long-term effects of universal preventive interventions conducted during middle school on 17-21-year-olds' prescription drug misuse...

..Relative reduction rates were calculated to quantify intervention-control differences on the estimated proportion of young adults indicating problematic substance use; they ranged from 19% to 31% for ISFP and from 9% to 16% for PDFY...

..We examined universal preventive intervention effects on adolescents' exposure to opportunities for substance use and on illicit substance use in the long term...

..The role of PROSPER's continuous, proactive technical assistance in producing the positive results is discussed...

..Community-based partnership models designed for sustained, quality implementation of proven preventive interventions have been recommended to address this problem. There is very limited longitudinal study of such models...

..The comprehensive strategy would require careful attention to the expansion of networks of effective partnerships, partnership-based research agendas, and requisite policy-making...

..Significant intervention-control differences were observed, indicating favorable delays in initiation in the intervention groups...

..Only SES was found to be significant as a predictor of assessment attrition. This SES result appeared to reflect an association between lower educational attainment and an increased likelihood of attrition...

..The paper concludes with discussion of the need for careful investigation of community-university partnership models as a key mechanism for large-scale implementation...

..A summary of how articles address these tasks concludes with a discussion of the importance of futher strengthening a public service orientation in prevention science...

..The paper presents an overview of the evolving partnership model and summarizes positive results of its implementation over a 12-year period in an ongoing project...

..This analysis compares the cost effectiveness of tvo interventions designed for general population families of adolescents. It also conservatively estimates their benefit-cost ratios and net benefits...

..The current investigation, while not directly examining substance use, further examined rural-urban differences in the distribution of risk factors for youth substance use, based on information from parent reports...

..It is concluded that brief family skills-training interventions designed for general populations have the potential to reduce adolescent substance use and thus have important public health implications...

..To examine the long-term effects of a brief family intervention on aggressive and hostile behaviors of adolescents in the general population...

..Effects on delayed substance use initiation were shown for both the ISFP and the PDFY at a 2-year follow-up. Also at this follow-up, the PDFY showed effects on delayed progression of use among those previously reporting initiation...

..The theoretical and applied implications of these findings are discussed...

..The potential for self-fulfilling prophecies to produce long-lasting changes in targets' behavior via self-verification processes are discussed...

..Gender differences also were found, although the intervention was effective in slowing the rate of increase in initiation for both genders...

..The authors discuss these findings in terms of the link between self-fulfilling prophecies and social problems...

..Findings suggest that there might be a social desirability bias in provider self-reported ratings of implementation and that caution must be used when interpreting self-reported ratings of implementation...

....

..The purpose of the current study was to investigate the influence of externalizing behaviors on substance initiation trajectories among rural adolescents over a 42-month period...

....

....

..Findings indicate the feasibility of developing universal preventive interventions that offer comparable benefits to all families...

..Changes in regulated, communicative parenting mediated the intervention's impact on youths' recognition of changes in parenting, which in turn was linked to changes in youths' high-risk behavior...

..No other self-fulfilling prophecy effects emerged. Findings are discussed in terms of family relations and the differential power of negative versus positive self-fulfilling prophecies...

..Intervention-induced changes in parenting mediated the effect of intervention group influences on changes in protective factors over a 7-month period...

..Relative reduction rates for alcohol initiation were 30.0% for the combined intervention and 4.1% for LST only...

..Findings illustrate the complexity of multiproblem youth...

..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...

..e., frequency of alcohol use, quantity of consumption, frequency of heavy episodic drinking, and frequency of problem use) were predictive of young-adult major depressive disorder (MDD)...

..Results also showed that peer substance use was a direct positive predictor of problem use...

..e., when mothers underestimated their children's future alcohol use). The findings are discussed in terms of parent-child relationship quality, peer influences, self theories, and out-group stereotypes...

....

..Indirect positive effects of delinquency on the outcome were observed for boys; direct positive effects of depressed mood were observed for girls. Prevention implications are discussed...

..EDITORS' STRATEGIC IMPLICATIONS: The authors identify barriers to successful long-term implementation of prevention programs and add to a small, but important, longitudinal research knowledge base related to community coalitions...
