Adolescent peer group identification and characteristics: a review of the literature.

This study provides an exhaustive review of 44 peer-reviewed quantitative or qualitative data-based peer-reviewed studies completed on adolescent peer group identification. Adolescent peer group identification is one's self-perceived or other-perceived membership in discrete teenage peer groups. The studies reviewed suggest that adolescent peer groups consist of five general categories differentiable by lifestyle characteristics: Elites, Athletes, Academics, Deviants, and Others. We found that the Deviant adolescent group category reported relatively greater participation in drug use and other problem behaviors across studies, whereas Academics and Athletes exhibited the least participation in these problem behaviors. Additional research is needed in this arena to better understand the operation of adolescent group labels.

Fidelity of implementation in Project Towards No Drug Abuse (TND): a comparison of classroom teachers and program specialists.

This paper presents the results of an effectiveness trial of Project Towards No Drug Abuse [TND], in which we compared program delivery by regular classroom teachers and program specialists within the same high schools. Within 18 schools that were randomly assigned to the program or control conditions, health classrooms were assigned to program delivery by teachers or (outside) specialists. Classroom sessions were observed by pairs of observers to assess three domains of implementation fidelity: adherence, classroom process, and perceived student acceptance of the program. Pre- and immediate posttest survey data were collected from 2331 students. Of the four composite indexes of implementation fidelity that were examined, only one (quality of delivery) showed a difference between specialists and teachers, with marginally higher ratings of specialists (p < .10). Both teachers and program specialists achieved effects on three of the five immediate outcome measures, including program-specific knowledge, addiction concern, and social self-control. Students' posttest ratings of the program overall and the quality of program delivery failed to reveal differences between the teacher- and specialist-led classrooms. These results suggest that motivated, trained classroom teachers can implement evidence-based prevention programs with fidelity and achieve immediate effects.

Five-year prospective prediction of self-initiated quitting of cigarette smoking of high-risk youth.

This paper provides a 5-year replication-extension of a previous 1-year follow-up study of the same sample of southern California alternative high school youth. Demographic, behavioral, psychosocial, and emerging adult function predictors of adolescent self-initiated smoking cessation were investigated. Based on the first (1-year) prospective study and this follow-up, one may speculate that smoking cessation programs for adolescents should include counteraction of problem-prone attitudes, assistance with job aspirations and information about drug-free workplaces, motivation to quit strategies, and assistance with overcoming withdrawal symptoms.

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.

Misuse of "study drugs:" prevalence, consequences, and implications for policy.

BACKGROUND: Non-medical/illegal use of prescription stimulants popularly have been referred to as "study drugs". This paper discusses the current prevalence and consequences of misuse of these drugs and implications of this information for drug policy. RESULTS: Study drugs are being misused annually by approximately 4% of older teens and emerging adults. Yet, there are numerous consequences of misuse of prescription stimulants including addiction, negative reactions to high dosages, and medical complications. Policy implications include continuing to limit access to study drugs, finding more safe prescription drug alternatives, interdiction, and public education. CONCLUSION: Much more work is needed on prescription stimulant misuse assessment, identifying the extent of the social and economic costs of misuse, monitoring and reducing access, and developing prevention and cessation education efforts.

Project Towards No Drug Abuse: long-term substance use outcomes evaluation.

OBJECTIVES: This paper presents up to 5 years post-program outcomes of Project Towards No Drug Abuse (Project TND), a drug abuse prevention program conducted in South California alternative high school system during years 1994-1999. METHODS: The effects of a 9-session health motivation--social skills--decision-making curriculum were evaluated. Twenty-one schools recruited were randomly assigned to standard care (control), classroom only, or a classroom plus semester-long school-as-community component. Last 30-day use of cigarettes, alcohol, marijuana, and hard drugs were assessed at three time intervals: short-term (year 1), middle-term (years 2 or 3), and long-term (years 4 or 5). Multilevel random coefficients modeling were employed to estimate the adjusted levels of substance use. RESULTS: Among 1578 baseline subjects, follow-up data were available for 68% (year 1), 66% (years 2 or 3), and 46% (years 4 or 5) of subjects, respectively. Results revealed significant positive long-term program effects for hard drug use at year 4 or 5 for the two program interventions (P = 0.02). CONCLUSIONS: Project TND reduced hard drug use in the 46% who were successfully followed. It is the first program to demonstrate long-term self-reported behavioral effects on hard drug use among high-risk youth by using a school-based, limited-session model.

A meta-analysis of teen cigarette smoking cessation.

OBJECTIVE: This article presents a meta-analysis of 48 teen cigarette smoking cessation studies, the 1st meta-analysis of its kind. The authors conducted searches of electronic databases and unpublished manuscripts from 1970 to 2003. Fifty contextual elements were coded from each article. A weighted least squares random effects method was used to pool results from individual study net effects estimates. Multilevel random coefficients modeling was applied to control for the intrastudy variation. MAIN OUTCOME MEASURES: The primary outcome for the present analysis was quit rate. Data were entered as intent-to-treat (ITT) quit rates (not compliance sample rates). Overall treatment effect size and treatment effect sizes as a function of program content, modality, number of sessions, and length of follow-up were examined. RESULTS: Across studies, program conditions, compared with control conditions, appeared to give smokers a 2.90% (95% confidence interval = 1.47-4.35%) absolute advantage in quitting, increasing the probability of quitting by approximately 46% (9.14% vs. 6.24%). Relatively higher quit rates were found in programs that included a motivation enhancement component, cognitive-behavioral techniques, and social influence approaches. Also, relatively higher quit rates were found in school-based clinic and classroom modalities. Furthermore, relatively higher quit rates were found for programs consisting of at least 5 quit sessions. Data also indicated that the effects were maintained at short-term (1 year or less) and longer term (longer than 1 year) follow-ups. CONCLUSION: Much more teen smoking cessation research is needed, but teen smoking cessation programming is effective, and the present study provides a framework to move forward.

Peer influences on adolescent cigarette smoking: a theoretical review of the literature.

This article reviews several classes of theories to elucidate the relationship between adolescent cigarette smoking and friends' cigarette smoking. Perceived influence theories hinge upon an adolescent's perception of friends' smoking behavior. External influence theories are those in which friends' smoking behavior overtly influences adolescent smoking. Group level theories examine how differences at the level of subculture, gender, and race/ethnicity influence the relationship under study. Network theories are also discussed. A model integrating relevant theories into a longitudinal model representing friend influences on adolescent smoking is presented, along with implications of the results presented for adolescent tobacco prevention programs.

Non drug use- and drug use-specific spirituality as one-year predictors of drug use among high-risk youth.

The present article explored two different dimensions of spirituality that might tap negative and positive relations with adolescent drug use over a 1-year period. Non-drug-use-specific spirituality measured how spiritual the person believes he or she is, participation in spiritual groups, and engagement in spiritual practices such as prayer, whereas drug-use-specific spirituality measured using drugs as a spiritual practice. Self-report questionnaire data were collected during 1997-1999 from a sample of 501 adolescents in 18 continuation high schools across southern California. Participants ranged in age from 14 to 19 and were 57% male, with an ethnic distribution of 34% White, 49% Latino, 5% African American, 7% Asian, and 5% other. A series of general linear model analyses were conducted to identify whether or not two different spirituality variables predict drug use (cigarettes, alcohol, marijuana, hallucinogens, and stimulants) at 1-year follow-up. After controlling for baseline drug use, non-drug-use-specific spirituality was negatively predictive of alcohol, marijuana, and stimulant use, whereas drug-use-specific spirituality failed to be found predictive of these variables one year later. Conversely, drug-use-specific spirituality was positively predictive of cigarette smoking and hallucinogen use, whereas non-drug-use spirituality failed to be found predictive of these variables. Our results provide new evidence that suggests that spirituality may have an effect on drug use among adolescents. The drug-use-specific measure of spirituality showed "risk effects" on drug use, whereas the other measure resulted in "protective effects," as found in previous research. Knowledge of the risk and protective patterns and mechanisms of spirituality may be translated into future drug use prevention intervention programs.

Translation in the health professions: converting science into action.

The systematic translation of evidence-based research findings, tools, and information into practice is critical to improving the quality of our nation's health. However, despite several decades of advances in developing medical knowledge based on high-quality empirical evidence, widespread implementation of these findings into practice in diverse applied settings has not been achieved. This article reviews definitions and conceptual models that describe the translation of research from basic discovery to real-world applications, summarizes the various issues involved in the process of translation, discusses multiple barriers, and provides recommendations to surmount these hurdles. Areas of further research in this arena are suggested. Finally, the article concludes that translational research is an important area to continue to pursue requiring long-term collaborative commitment among researchers and practitioners.

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.

Type II translation: transporting prevention interventions from research to real-world settings.

This article summarizes research on Type II translation of prevention interventions aimed at enhancing the adoption of effective programs and practices in communities. The primary goal of Type II translation is to institutionalize evidence-based programs, products, and services. First, the authors describe theoretical frameworks that are useful to guide Type II translation research. Second, research on prevention program implementation, including fidelity of implementation and factors that are associated with successful program implementation, is summarized. The authors describe interventions designed to enhance the dissemination of preventive interventions in community and public health settings. Third, they describe strategies used by prevention program developers who have taken programs to scale. Fourth, they present a case example of Project Towards No Drug Abuse (TND), an empirically validated high school-based substance abuse prevention program. They describe ongoing research on the dissemination of Project TND. Finally, they provide suggestions for future Type II translation research.

The transdisciplinary-translation revolution: final thoughts.

A transdisciplinary-translation matrix is posited as a new direction reflected by the work presented in this and the two previous special issues. In fact, the demands inherent in this matrix suggest that a revolution in health research is in the works. Potential barriers and future directions of the matrix are suggested.

Motivation to quit as a mediator of tobacco cessation among at-risk youth.

The purpose of this study is twofold: 1) to evaluate the effects of a smoking cessation clinic (Project EX) on changing motivation to quit smoking, and 2) to assess differences in quit rates based on these changes in motivation. Student smokers in 18 continuation high schools in the Los Angeles county area were invited to participate in a tobacco cessation clinic designed to enhance motivation to quit tobacco use. The 18 schools were randomly assigned to one of three conditions. Compared to students in the control group, students who participated in the program conditions were more likely to express higher motivation to quit tobacco use. Higher motivation was also significantly related to higher quit rates. Motivation to quit as defined by constituents of the energy/direction model of motivation appears to be a plausible mediator of cessation program effects.

Risk factors for and prevention of tobacco use.

This study describes the risk factors for and prevention of tobacco use among young people. Risk factors show differential importance along the course of tobacco use development. The contents of an effective prevention effort vary as a function of the age of target group. However, the mediation of the effects of effective programs is not well known. Various modalities of implementation of prevention programming may be important, though a majority of program evaluation has occurred in the school context. The majority of well-evaluated tobacco use prevention programs that employ a comprehensive social influences model show effects over an average of 6 years post-programming.

Explaining the link between violence perpetration, victimization and drug use.

This study examined relationships between illegal and legal drug use and violence perpetration and victimization as well as possible mediators of these relationships. Subjects were continuation high school students followed prospectively over 5 years. Results indicated that illegal drug use predicted violence and victimization 5 years later and that earlier victimization was also associated with later illegal drug use. A measure intending to tap a psychopharmacological effects system, consistent with its definition in [Goldstein, P. J. (1985). The drugs/violence nexus: A tripartite conceptual framework. Journal of Drug Issues, 15(4), 493-506] tripartite model, was found to mediate the relationships between illegal drug use and victimization and violence. Results suggest that violence and victimization prevention efforts may benefit by addressing the psychopharmacological effects of adolescent illegal drug use.

Prevention of adolescent alcohol problems in special populations.

Research on the prevention of alcohol abuse in America has only recently begun to consider the needs of special populations. This chapter will consider alcohol prevention as a function of four major special population divisions: gender, ethnicity, region (population density), and socioeconomic status. Specific ethnic groups examined will include Hispanics, African-Americans, Asian-Americans, and Native Americans. In general, there is some support for the utility of current alcohol prevention approaches on special populations. Much population-specific work completed to date has not been rigorously designed or evaluated, though it appears likely that partnering with population gatekeepers and showing cultural respect and sensitivity to the population, and providing material that is relevant to the population's adaptation to their environment are essential.

A pilot study of an alcoholic liver disease recurrence prevention education program in hospitalized patients with advanced liver disease.

No systematic work has been completed to assess whether or not educational programming might exert lifestyle improvements among alcoholic liver disease (ALD) inpatients. The present pilot study sought to answer this question through the use of a small-scale two-group experiment (five-session education program versus standard care) at a state-of-the art Liver Unit that provided tertiary care of indigent patients with advanced ALD. A total of 44 patients were initially randomly assigned to program conditions, and 25 provided 3-month follow-up data (13 in the program condition, 12 in the control condition). Patients who received the program reported high receptivity to it, and showed greater learning of program material and reported greater lifestyle changes than the control patients. For those ALD inpatients that are able and willing to participate, the program shows promising effects on self-reported lifestyle change.
