The effects of No Child Left Behind on the prevalence of evidence-based drug prevention curricula in the nation's middle schools.

BACKGROUND: Concerns have been expressed that No Child Left Behind (NCLB) may be reducing the amount of classroom time devoted to subjects other than those for which students are tested. The purpose of this article is to explore whether NCLB legislation has affected the provision of evidence-based drug prevention curricula (EBC) in the nation's middle schools, a subject area that is not assessed by standardized tests. METHODS: Data were collected in spring 2005 and spring 2008 from a nationally representative sample of middle schools. Respondents completed a survey regarding their provision of EBC (2005 response rate: 78.1%). We also collected data on schools' adequate yearly progress (AYP) status as of 2005 as a measure of their compliance with NCLB targets. We restricted our sample to schools that responded to our survey in both waves (n = 1324, or 76.9% of those schools responding in 2005) and conducted logistic regression analyses to determine whether those schools not making AYP in 2005 were less likely to be using an EBC in 2008. RESULTS: Our results revealed no relationship between AYP status in 2005 and EBC use in 2008. Analyses of demographic characteristics showed that schools making AYP were more likely to be small and rural, and to serve majority White student populations whose families were characterized by lower levels of poverty. CONCLUSIONS: Our failure to find any relationship between AYP status and the provision of EBC suggests that concerns about the potential adverse effects of NCLB on drug use prevention have yet to be validated. Implications of our results are discussed.

The prevalence of evidence-based substance use prevention curricula in the nation's elementary schools.

Current guidelines for school-based substance use prevention suggest that prevention efforts should begin in elementary grades, before students begin using substances. Previous research suggests, however, that the use of evidence-based curricula in these grades may be low. Using a 2005 survey of public school districts in the United States that include elementary grades (n = 1563), we assessed the prevalence of elementary curricula use, particularly those designated as evidence-based. We found that although 72% of districts administer a substance use prevention curriculum to their elementary students, only about 35% are using one that is evidence-based and only about 14% are using an evidence-based curriculum more so than any other prevention curriculum. We present prevalence estimates for specific evidence-based curricula and conclude by discussing possible reasons for and implications of our findings.

Implementing evidence-based substance use prevention curricula with fidelity: the role of teacher training.

It is widely recognized that teacher training affects the fidelity with which evidence-based substance use prevention curricula are implemented. We present the results of a 2005 survey of teachers from a nationally representative sample of 1721 public middle schools in the U.S. (78.1% response rate). We measured fidelity along two dimensions (adherence and dose) and also assessed the number of hours, recency, and perceived effectiveness of teachers' training, as well as the degree to which adherence was emphasized during training. Among teachers using evidence-based curricula, 35.3% reported following their curriculum guide very closely. The average proportion of lessons taught was 64.9%, and only 30.2% of teachers taught all the lessons in their curriculum. Analyses revealed that teachers whose training emphasized adherence were 5 times as likely to be more adherent. We present recommendations for training-related factors that may increase fidelity of implementation.
