Short-term effects of Project EX-4: a classroom-based smoking prevention and cessation intervention program.

OBJECTIVE: Researchers continue to try to develop effective teen tobacco use prevention and cessation programs. Three previous school clinic-based studies established the efficacy of Project EX for teen smoking cessation. This fourth study adapts Project EX to the classroom context. This paper reports the findings based on pretest and posttest surveys conducted immediately prior and post-intervention. METHODS: An eight-session classroom-based curriculum was developed and tested with a randomized controlled trial that involved a total of 1097 students in six program and six control continuation high schools. Program-specific knowledge and smoking measures were assessed at both the pretest and posttest surveys, and were used to evaluate the program's effect on the immediate outcomes. The immediate outcomes effects were analyzed with multi-level random coefficients models. RESULTS: Program students provided favorable process ratings of the overall program and each session. Compared with the students in the control condition, students in the program condition showed a greater change in correct knowledge responses from pretest to posttest (beta=+5.5%, p=0.0003). Students in the program condition also experienced a greater reduction in weekly smoking (beta=-6.9%, p=0.038), and intention for smoking in the next 12 months (beta=-0.21 in 5-level scale, p=0.023). CONCLUSIONS: EX-4 immediate outcome results revealed favorable student responses to the program, increases in knowledge, and decreases in smoking relative to a standard care control condition.

Translation in tobacco and drug abuse prevention research.

The purpose of this article is to describe the translation of research on tobacco and drug abuse prevention from basic science to program development to large-scale program dissemination, and from animal to human studies. Where relevant, continuity of translation is discussed by referring to two variables that have been studied for their potential relationship to drug use risk in both animals and humans: sensation and novelty seeking and low impulse control. Review of the research indicates relatively slow translation until the early 1990s. The authors recommend several mechanisms to promote more rapid translation across types of research that encourage reciprocal rather than unidirectional transmission of knowledge to expedite the development and diffusion of more timely, targeted drug abuse prevention programs.

Factors associated with adoption of evidence-based substance use prevention curricula in US school districts.

This paper examines factors associated with the adoption of evidence-based substance use prevention curricula (EBC) in a national sample of school districts. Substance abuse prevention coordinators in public school districts (n = 1593), which were affiliated with a random sample of schools that served students in Grades 5-8, completed a written survey in 1999. Results indicated that 47.5% of districts used at least one EBC in their schools with middle school grades. Substance use prevention coordinators reported they had the greatest input in decisions about curricula. In a multivariate analysis of factors positively associated with district-level decisions to adopt evidence-based programs, significant factors included input from a state substance use prevention group, use of information disseminated by the National Institute on Drug Abuse or Center for Substance Abuse Prevention, use of local needs assessment data, consideration of research showing which curricula are effective and allocation of a greater proportion of the coordinator's time to substance use prevention activities. State and federal agencies should increase their efforts to disseminate information about evidence-based programs, targeting in particular the district substance use prevention coordinator.

An evaluation of the fidelity of implementation of a school-based drug abuse prevention program: project toward no drug abuse (TND).

This article provides an implementation fidelity evaluation of the fourth experimental trial of Project Towards No Drug Abuse (TND). Two theoretical content components of the curriculum were examined to increase our understanding of the active ingredients of successful drug abuse prevention programs. A total of 18 senior high schools were randomly assigned by block to receive one of three conditions: cognitive perception information curriculum, cognitive perception information + behavioral skills curriculum, or standard care (control). These curricula were delivered to both regular and continuation high schools students (n=2331) by trained project health educators and regular classroom teachers. Across all program schools, the two different curricula were implemented as intended, were received favorably by students, and showed significant improvements in knowledge specific to the theoretical content being delivered. This pattern of results suggests that the experimental manipulations worked as intended, and thus, permit the attribution of future behavioral outcome differences between conditions to differences in content of Project TND material provided rather than to differences in the fidelity of delivery. Further, our findings indicate that Project TND can be implemented effectively with low and high risk youth in a general environment as well as with high risk youth in a more specialized environment.

Reasons for teachers' adaptation of substance use prevention curricula in schools with non-white student populations.

In this study we investigate reasons why teachers adapt substance use prevention curricula in the nation's middle schools. We hypothesize that these reasons will be most salient in schools with racially and ethnically diverse student populations, for whom teachers may believe it appropriate to tailor their curricula. The study sample comprised a nationally representative sample of lead substance use prevention teachers in the nation's middle schools. Respondents answered questions concerning eight student problems or needs that constituted reasons why they might adapt their prevention lessons. Controlling for a variety of school and teacher characteristics, we found that teachers in high minority schools were more likely to adapt curricula in response to three of the eight characteristics presented: youth violence, limited English proficiency, and various racial/ethnic or cultural groups. We suggest that curriculum developers make a systematic effort to understand how teachers are adapting their curricula in high minority schools and incorporate these modifications, if found effective, into their curricula.

Who's calling the shots? Decision-makers and the adoption of effective school-based substance use prevention curricula.

This study investigates the relative roles of school district and school-level decision-makers in the implementation of effective substance use prevention curricula. Drawing on a "Site-Based Management" approach to effective decision-making, we hypothesized that schools whose personnel played active decision-making roles would be more likely to implement effective curricula than those in which decision-making was the prerogative of school district personnel. Study data comprised 1369 questionnaires completed by a representative national sample of both district-level prevention coordinators and middle school-based lead prevention teachers. From the perspective of the lead prevention teachers, the school district-level prevention coordinator was more influential than school staff in selecting effective prevention curricula. However, we did find some support for our hypothesis from our district-level informants, who indicated that community groups and advisory committees also play a modest role in the selection of such curricula.

Social network predictors of bullying and victimization.

This study examined whether bullies, victims, and aggressive victims (those who are both bullies and victims) differed on classroom social network variables, gender, and ethnicity. Survey data were collected from a primarily Latino and Asian sample of 1,368 Southern California 6th graders (mean age = 11.3 years). Logistic regression analyses were performed to determine whether network characteristics and ethnicity were associated with each of the outcome variables. Consistent with social cognitive theory, friends' participation in aggressive behaviors was positively associated with being a bully or an aggressive victim, and negatively associated with being a victim. Consistent with social dominance theory, the number of friendship nominations received was negatively associated with being a victim. Female bullies received fewer friendship nominations, but had a higher proportion of reciprocated friendships. Victims were disproportionately Asian. The findings suggest that bullying prevention efforts targeting highly aggressive students may also diffuse to their friends, and that assertiveness training in handling aggressive situations may successfully combat bullying and aggression.

Political science, public policy, and drug use prevention.

Increasingly, drug use prevention programs and research are being considered in the environmental contexts in which they occur. One context that is rarely considered is the political context. This article examines the reciprocal effects of policy and prevention programs from four perspectives representing different contexts, beginning with political science, and followed by social work and public health administration, psychology, and education. Four specific issues are considered. First is how current national policies on drug use shape our nation's prevention efforts, from a political science perspective. Second is how effective prevention programs can affect and shape policy change. This issue is considered from a social and public health administration perspective. Third is how policy change can act as an intervention to prevent drug use, from the perspective of psychology. The fourth issue is how dissemination of prevention programs and policies can impact drug use prevention. This question considers an educational perspective. The perspectives are integrated into a general conceptual model to improve our understanding of how drug use prevention occurs in a national political context. Finally, examples are given of how this model might inform the other perspectives represented in this special issue on transdisciplinary drug abuse prevention research.

Smoking behavior among urban and rural Native American adolescents in California.

BACKGROUND: Previous studies have documented a high prevalence of tobacco use among Native American adolescents. However, little is known about the smoking behavior of Native American adolescents who live in urban areas. This study used statewide data from California to examine the smoking behavior and related psychosocial risk factors among Native American adolescents living in urban and rural counties. METHODS: The Independent Evaluation of the California Tobacco Control Program conducted three population-based statewide surveys of 10th-grade California public school students in 1996, 1998, and 2000. Past-month smoking and psychosocial correlates were examined among 22,440 respondents, including 1060 Native Americans. RESULTS: Native Americans had a 32% excess risk of past-month smoking compared with other ethnic groups. Smoking prevalence did not differ between urban (27.7%) and rural (29.3%) Native Americans. Native Americans reported higher access to cigarettes and exposure to smoking peers than other groups. Those psychosocial variables explained some, but not all, of the excess risk of smoking among Native Americans. CONCLUSIONS: Effective smoking prevention and cessation interventions are needed for Native American adolescents in urban and rural areas of California.

A comparison of current practice in school-based substance use prevention programs with meta-analysis findings.

The series of seminal meta-analytic studies of school-based substance use prevention program studies conducted by the late Nancy S. Tobler and colleagues concluded that programs with content focused on social influences' knowledge, drug refusal skills, and generic competency skills and that use participatory or interactive teaching strategies were more effective than programs focused on knowledge and attitudes and favoring traditional didactic instruction. The present study compared current school practice against evidence-based standards for "effective content" and "effective delivery," derived from the Tobler findings. Respondents were the lead staff who taught substance use prevention in the 1998-1999 school year in a national sample of public and private schools that included middle school grades (N = 1,795). Results indicate that most providers (62.25%) taught effective content, but few used effective delivery (17.44%), and fewer still used both effective content and delivery (14.23%). Those who taught an evidence-based program (e.g., Life Skills Training, Project ALERT), however, were more likely to implement both effective content and delivery, as were those teachers who were recently trained in substance use prevention and were comfortable using interactive teaching methods. The findings indicate that the transfer to practice of research knowledge about school-based substance use prevention programming has been limited.

Sexual decision making and safer sex behavior among young female injection drug users and female partners of IDUs.

Data from interviews with 94 young women who were injection drug users (IDUs) or partners of IDUs were analyzed to examine associations between self-reported sexual decision making and condom use, contraceptive use, and relationship characteristics. Most women (73-85%) reported participating in decisions about condom use, contraception, and when to have sex. Adjusting for potential covariates, respondents who reported participating in decisions about condom use and when to have sex were 7 and 19 times, respectively, more likely than others to report recently using condoms. Respondents who reported participating in decisions about contraception were 20 times more likely than others to report recently using contraceptives. Longer sexual relationships were associated with decreased likelihood of condom or contraceptive use.

The principles of effectiveness: early awareness and plans for implementation in a national sample of public schools and their districts.

The US Department of Education's Principles of Effectiveness require recipients of Safe and Drug-Free Schools and Community Act funds to: a) base drug and violence prevention programs on needs assessment data, b) develop measurable program goals and objectives, c) implement programs with research evidence of effectiveness, and d) periodically evaluate programs relative to their goals and objectives. This paper reports the extent of awareness of the Principles of Effectiveness and plans for their implementation among public school districts and schools in the United States in the year following their announcement. Results showed a greater percentage of public school districts than individual schools knew about the principles and planned for implementation, but baseline levels of awareness for both districts and schools were relatively low. Schools were more likely to know about the principles when their associated school district also knew. Results suggest a need for greater communication about the principles to school districts, and in turn, a need for greater communication between district and school-level substance use prevention staff.

Peer influences and access to cigarettes as correlates of adolescent smoking: a cross-cultural comparison of Wuhan, China, and California.

BACKGROUND: Few studies have assessed the effects of access to cigarettes and peer influences on adolescent smoking in non-Western countries. Using samples characterized by two distinct cultural, social, and economic systems, this study evaluated the associations of friends' smoking and perceived access to cigarettes with adolescent smoking behavior in California and Wuhan, China. METHODS: Survey data were obtained from 5870 eighth-grade students in the Independent Evaluation of the California Tobacco Control Program and 6992 seventh- to ninth-grade students in the Wuhan Smoking Prevention Trial. Odds ratios for lifetime and 30-day smoking, according to friends' smoking and perceived access to cigarettes, were calculated for boys and girls in both samples and compared. RESULTS: California students were more likely than Wuhan students to have friends who smoked and to perceive easy access to cigarettes. The smoking prevalence was lower in Wuhan than in California, mainly due to the low smoking prevalence among Wuhan girls. Friends' smoking was strongly associated with smoking in both samples, and the strength of this association did not differ between the two cultures. Access to cigarettes was associated with a higher risk of lifetime smoking in both cultures and a higher risk of past 30-day smoking in California only. CONCLUSIONS: Despite divergent tobacco control policy enforcement, social structures, and cultural contexts, similarities exist between Wuhan and California. The findings suggest support for adapting a social-influences-based smoking prevention program developed in the United States to the culturally specific needs of youth in Wuhan, China.

The prevalence of effective substance use prevention curricula in U.S. middle schools.

Despite an abundance of evaluative evidence concerning the effectiveness of several school-based substance use prevention curricula, many of the nation's middle schools continue to implement curricula that are either untested or ineffective. This study reports the prevalence of substance use prevention curricula in the nation's public and private schools that contain middle school grades. We also report school- and respondent-related background characteristics differentiating schools using at least 1 effective curriculum from those using ineffective or untested curricula. Respondents comprised the lead staff who taught substance use prevention in a representative sample of 1,905 of the nation's public and private schools that include middle school grades. Data were collected in 1999 by means of a self-administered survey. Altogether, 26.8% of all schools, including 34.6% of public schools and 12.6% of private schools, used at least 1 of the 10 effective curricula specified. Few school or respondent characteristics were related to program implementation. Over two thirds of schools reported using more than 1 curriculum, and almost half reported using 3 or more. Results demonstrate the considerable gap between our understanding of effective curricula and current school practice. Prevention researchers and practitioners should work closely together to find ways to increase the proportion of schools implementing effective curricula.

Gender differences in HIV risk behaviors among young injectors and their social network members.

Using epidemiological and social network research methods, this study examines gender differences in HIV risk and protective behaviors and social network characteristics among 193 young injection drug users (IDUs) and 127 referred members of their social networks. Respondents reported on their drug use, sexual behavior, and relationships within three types of social networks: hang out (i.e., friendship); drug use; and sexual networks. Most respondents were homeless and had experienced numerous life stressors. Females' social networks consisted more predominantly of drug injectors, and members more frequently appeared multiple networks. Females reported needle sharing more frequently than males, but also reported more protective behaviors such as needle exchange use and carrying clean syringes. Young female IDUs may compound their risk by having sex and injecting with higher risk partners. However, their propensity to practice protective behaviors may provide an opening for interventions to reduce their HIV risk and that of their social network members.

Independent evaluation of the California Tobacco Control Program: relationships between program exposure and outcomes, 1996-1998.

OBJECTIVES: This study sought to determine the effects of the California Tobacco Control Program on tobacco-related attitudes and behaviors. METHODS: In 1996 and 1998, a telephone survey was conducted among adults in randomly selected households in 18 California counties. Tenth-grade youths in 84 randomly selected high schools completed a written survey. In analyses conducted at the county level, differences in outcomes were regressed on an index of program exposure. RESULTS: Among adults, program exposure was associated with decreased smoking prevalence rates, increased no-smoking policies in homes, and decreased violations of workplace no-smoking policies. Among youths, there was no effect of program exposure on outcomes. CONCLUSIONS: These results suggest that the California Tobacco Control Program may have reduced adult smoking prevalence rates and exposure to environmental tobacco smoke.
