Despite a substantial proportion of high school students who initiate substance use following middle school, the implementation of universal evidence-based prevention curricula appears to be scant. We report data collected in 2005 from 1392 school-district based drug prevention coordinators, from a national, representative study of school-based substance use prevention practices. Altogether, 10.3% of districts that included high school grades reported administering one of six such curricula that were then rated as effective by the Substance Abuse and Mental Health Services Administration’s National Registry of Effective Programs and Practices or Blueprints for Violence Prevention, and 5.7% reported that they used one of these curricula the most. Only 56.5% of the nation’s districts with high school grades administered any substance use prevention programming in at least one of their constituent high schools.
Since the promulgation of its Principles of Effectiveness in 1998, the Office of Safe and Drug-Free Schools of the U.S. Department of Education has promoted the use of evidence-based drug prevention programs in the nation’s schools. We report the results of a survey, conducted in 2005, of a nationally representative sample of 1,721 schools with middle school grades. Respondents comprised the staff member in the school identified as most knowledgeable about the school’s drug prevention programs. The total response rate was 78%. Respondents answered questions concerning which drug use prevention curricula they used, and, if they used more than one, which one they used the most frequently. Three federally-sponsored registries were used to specify which curricula were considered evidence-based. Findings from 2005 were then compared to earlier estimates based on a similar 1999 survey. We found that 42.6% of the nation’s schools with middle school grades were using an evidence-based curriculum, an increase of 8% from our 1999 estimate. The two most prevalent curricula in use, at 19% each, were Life Skills Training and Project ALERT. We note, however, that only 8% of Life Skills Training users and 9% of Project ALERT users reported using those curricula the most, and that only 23% of respondents overall reported that they used an evidence-based curriculum the most. More information is needed as to why over three-quarters of the nation’s schools with middle school grades continue to administer curricula that have not been identified as effective.
Fidelity of program implementation under real-world conditions is a critical issue in the dissemination of evidence-based school substance use prevention curricula. Program effects are diminished when programs are implemented with poor fidelity. We assessed five domains of fidelity--adherence, exposure (dosage), quality of delivery, participant responsiveness and program differentiation (lack of contamination from other programs)--in a subset of respondents (N = 342) from a national random sample of public schools with middle school grades (N = 1721). Respondents taught 1 of 10 evidence-based universal substance use prevention programs as their primary program during the 2004-05 school year. Their responses to survey questions about their recent implementation practices indicated that fidelity was high for quality of delivery and participant responsiveness, low for program differentiation and modest for adherence and exposure--the two core domains of fidelity. Results suggest the need for continued emphasis on fidelity in program materials, trainings and on-going technical support. Particular attention should be paid to supporting use of interactive delivery strategies.
Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se.
The No Child Left Behind Act mandates the implementation of evidence-based drug prevention curricula in the nation’s schools. The purpose of this paper is to estimate changes in the prevalence of such curricula from 2005 to 2008. We surveyed school staff in a nationally representative sample of schools with middle school grades. Using a web-based approach to data collection that we supplemented by telephone calls, we secured data from 1892 schools for a response rate of 78.2%. We estimate that the prevalence of evidence-based drug prevention curricula rose from 42.6% in 2005 to 46.9% in 2008, and that the prevalence of schools that used these curricula most frequently increased from 22.7% to 25.9% over this period. In addition, the proportion of schools using locally developed curricula also rose, from 17.6% to 28.1%. This study suggests the success of efforts by the Office of Safe and Drug-Free Schools to increase the prevalence of evidence-based curricula, as well as the need to continue to track the prevalence of these curricula in response to any reductions in the Office’s fiscal support for evidence-based drug prevention curricula in the nation’s schools.
We examined whether parental monitoring at baseline predicted subsequent substance use in a high-risk youth population. Students in 14 alternative high schools in Washington State completed self-report surveys at three time points over the course of 2 years. Primary analyses included 1,423 students aged 14-20 who lived with at least one parent or step-parent at baseline. Using hierarchical linear modeling, we found that high parental monitoring at baseline predicted significantly less use of alcohol, marijuana, downers, cocaine, PCP, LSD, and prescription drugs and drinking to intoxication at the first posttest. Approximately 1 year later, high parental monitoring at baseline predicted significantly less use of alcohol, cocaine, prescription drugs, uppers, and ecstasy and drinking to intoxication. Study results suggest that parental monitoring serves as a protective factor, even for high-risk alternative high school students. Including a parental monitoring component may increase the effectiveness of traditional drug prevention programs.
To help tobacco control research better include vulnerable populations, we sought to identify effective ways to recruit diverse smokers. In 2014–2015, we recruited 2149 adult cigarette smokers in California and North Carolina, United States, to participate in a randomized trial of pictorial cigarette pack warnings. The most effective means of recruiting smokers were the classified advertising website Craigslist (28% of participants), word of mouth (23%), Facebook (16%), and flyers or postcards (14%). Low-income and African American smokers were more likely to respond to interpersonal contact (including staff in-person recruitment and word of mouth) than were high-income and non-African American smokers (all p < 0.05). Hispanic and gay, lesbian, and bisexual smokers were more likely to be recruited by Craigslist than non-Hispanic and straight smokers (both p < 0.05). Of the recruitment methods requiring cost, the cheapest was Craigslist ($3–7 per smoker). The most expensive methods were newspaper ads in California ($375 per smoker) and staff in-person recruiting in North Carolina ($180 per smoker). Successfully recruiting diverse smokers requires using multiple methods including interpersonal, online, and other media. Craigslist and word of mouth are especially useful and low-cost ways to recruit diverse smokers.
