A review of the literature suggests that early substance initiation is related to a variety of negative outcomes, including substance misuse or abuse in adolescence and adulthood. This study examines potentially modifiable predictors of early substance initiation, including both family and peer factors known to influence early initiation. A theoretically derived model of substance initiation was tested using structural equation modeling. Results indicate that both family and peer factors have an impact on early substance initiation when children in this sample were 11 and 12 years old. The model explained 60% of the variance in substance initiation. Prosocial family processes (rules, monitoring, and attachment) had a significant impact on child peer association, decreasing involvement with antisocial peers. These prosocial family processes had a significant negative effect on substance initiation even while modeling the influence of antisocial peers. Implications for drug use prevention practice are discussed. [ABSTRACT FROM AUTHOR]

Among populations identified by the U.S. Bureau of the Census, it is anticipated that the Asian/Pacific Islander (API) population will experience the greatest change between 1990 and 2050 (U.S. Bureau of the Census. [1996, February]. Current population reports. Series P25-1130. Washington, DC: U.S. Government printing office). Limited studies focus on APIs as a racial group and still fewer disaggregate samples to specific ethnic Asian subgroupings. This paper begins with definitions of the API communities, then examines rates of adolescent drug use, risk and protective factors, and preventive intervention effectiveness focused on API communities. The limited epidemiological data suggest that in general, APIs are at a relatively lower risk for drug use than youth from most other ethnic groups. However, the available data also suggest that use may not be as low as generally assumed with rates for alcohol use, smoking, and some illicit drugs being equal to or exceeding those of African Americans and European Americans. Despite the paucity of available data on particular Asian subgroups, the available data demonstrate that there are differences among API subgroups, underscoring the importance of identifying Asian subgroups when studying substance use and when planning prevention and treatment. The limited data examining the etiology of drug use across API subgroups suggests that some of the risk and protective factors derived from majority based research may also be predictors for these populations. These data support the utility of examining the generalizability of existing tested prevention approaches among different API communities. Finally, further efforts should be made to encourage and support the evaluation of community-based programs that already target and deliver services to API youth. [ABSTRACT FROM AUTHOR]

Child attachment to parents has been shown in the literature to reduce the likelihood of problem behaviors through enhancing resiliency. Research examining attachment and its relationship to antisocial behavioral outcomes in adolescents has been shaped largely by social control theorists who have theorized that attachment to prosocial others inhibits the expression of antisocial behavioral outcomes (Hirschi, 1969). This paper seeks to expand the literature by investigating the development of child attachment to parent(s) during the early elementary school years as specified theoretically by the social development model (Catalano & Hawkins, 1996). Using structural equation modeling, the results support the theoretical model as proposed by the social development model. School-aged children's attachment to parents can be successfully predicted by constructs outlined in the social development model. Finally, implications for interventions that enhance child attachment to parent(s) are discussed. [ABSTRACT FROM AUTHOR]

Raising Healthy Children is a cluster-randomized study of a school-based intervention aimed at preventing problem behaviors among children recruited into the project in the first or second grade of elementary school. Multilevel analysis was used to compare students in intervention and control schools with respect to whether they transferred out of their original schools. Students in intervention schools were less likely to transfer within the first 5 years of the project. A multilevel discrete-time survival model that included both time-varying and contextual variables revealed that the difference in hazard of transfer was greatest in the earlier years of the project.

The past decade has seen increasing recognition in prevention science of the need to move away from a black box approach to intervention evaluation and toward an approach that can elaborate on the mechanisms through which changes in the outcomes operate (Chen & Rossi, 1989; Durlak & Wells, 1997; Spoth et al., 1995). An approach that examines issues of program implementation is particularly critical in the design of efficacy studies of school-based preventive interventions. Numerous preventive intervention strategies are now delivered within the schools, often by regular classroom teachers. The extent to which teachers faithfully deliver a particular curriculum or incorporate instructional strategies emphasized by an intervention is a critical question for the overall project evaluation. This article illustrates the utilization of process measures from a multicomponent school-based prevention program to examine implementation of a teaching staff development intervention, and the program's underlying theoretical basis. Given the nested study design, the analyses utilize hierarchical linear models (Bryk & Raudenbush, 1992) to examine changes in teaching strategies by condition and investigate the hypothesized relationships between teaching practices and student behaviors based on the program's theoretical framework. Results suggest that teaching practices in two of the six intervention focus areas were positively impacted in the first 18 months of the project. Findings also support the relationships between teachers' instructional practices and students' behavior.

TOGETHER! Communities for Drug-Free Youth demonstrated the Communities That Care community mobilization strategy for risk-focused prevention of adolescent substance abuse. The project mobilized 35 Oregon communities to conduct quantitative assessments of community risk factors and protective resources, to develop comprehensive prevention plans incorporating promising approaches to priority risk factors, and to implement their plans. At the end of the four-year demonstration, 31 communities remained active in the project, which Oregon has institutionalized. The Communities That Care strategy, process results, and case examples are described. Implications for comprehensive prevention models of adolescent substance abuse and other problem behaviors are explored.
