ABSTRACT

The national Monitoring the Future (MTF) study examines substance use among adolescents and adults in the United States and has used paper questionnaires since it began in 1975. The current experiment tested three conditions as compared to the standard MTF follow-up protocol (i.e., MTF Control) for the first MTF follow-up survey at ages 19/20 years (i.e., one or two years after high school graduation). The MTF Control group included participants who completed in-school baseline surveys in the 12th grade in 2012-2013 and who were selected to participate in the first follow-up survey in 2014 (n = 2,451). A supplementary sample of participants who completed the 12th grade baseline survey in 2012 or 2013 but were not selected to participate in the main MTF follow-up (n = 4,950) were recruited and randomly assigned to one of three experimental conditions: (1) Mail Push, (2) Web Push, (3) Web Push + E-mail. Results indicated that the overall response rate was lower in Condition 2 compared to MTF Control and to Condition 1; there were no differences between Condition 3 and other conditions. Web response was highest in Condition 3; among web responders, smartphone response was also highest in Condition 3. Subgroup differences also emerged such that, for example, compared to white participants, Hispanics had greater odds of web (versus paper) response and blacks had greater odds of smartphone (versus computer or tablet) response. Item nonresponse was lowest in the Web Push conditions (compared to MTF Control) and on the web survey (compared to paper). Compared to MTF Control, Condition 3 respondents reported higher rates of alcohol use in the past 30 days. The total cost was lowest for Condition 3. Overall, the Condition 3 Web Push + E-mail design is promising. Future research is needed to continue to examine the implications of web and mobile response in large, national surveys.

ABSTRACT

This report identifies the prevalence of state, local, and commercially developed substance abuse prevention programs in middle and high schools from 2001 to 2007, using survey data from nationally representative samples of 1,206 schools. Based on school administrators' reports, schools and school districts offer students an average of 1.62 prevention programs during their school years from elementary through high school. Bivariate and multivariate regression analyses were conducted with school demographic characteristics public versus private, size, population density, region of the country, school race/ethnic composition, and socioeconomic status of the student body (SES) as predictors of total number of programs that students received and of the relative use of local, state, and commercial programs. Schools in the West had significantly fewer prevention programs than those in other regions of the country. Students in predominantly White and in higher SES schools received significantly more prevention programs than students in majority African American, majority Hispanic, or in lower SES affluent schools. The most frequently reported programs that students received were locally developed. D.A.R.E. was the most widely adopted prevention program. Findings from this study suggest that schools often develop their own curriculum to suit their students' needs, and students are exposed to multiple prevention programs through their school years, making it difficult to examine the effectiveness of any single program in preventing and reducing substance use among students.

ABSTRACT

The purposes of this study were to: a) identify trajectory groups of frequent marijuana use during emerging adulthood, b) distinguish among trajectory groups according to demographic and lifestyle characteristics, and c) examine how the trajectory groups relate to behavioral, attitudinal, and social-emotional correlates over time. National panel data from the Monitoring the Future study were used: 18 cohorts of high school seniors (classes of 1977-94) were followed biennially through age 24. Frequent marijuana use was defined as 3+ occasions of use in past month and/or 20 to 40+ occasions in past year. Based on four waves of complete longitudinal data (N=19,952), six frequent marijuana use trajectory groups were identified: chronic, decreased, increased, fling, rare, and abstain. Categorical analyses revealed trajectory group differences in demographic and lifestyle characteristics at senior year and age 24. The trajectory groups varied significantly in longitudinal patterns of other substance use, problem behaviors, and well-being.
