“…Student's t-tests for independent samples were used to detect differences at the baseline between the groups where appropriate. A posteriori power analysis of the study was performed according to the formulae in Janega et al [28]. Data are reported as mean±SD or as 95% confidence interval (CI).…”

“…Across the 2 school-based samples, the intraclass correlations (ICC) for the substance use outcomes were relatively high, ranging between 0.02 and 0.08. 41 Hence, in order to account for the school-level random effects, multilevel logistic regressions were conducted using the GLIMMIX procedure on all substance use outcomes for both samples except the marijuana and hard drug use outcomes in the Russian sample. In the Russian data, one or more schools had one or none recent marijuana or hard drug users.…”

Objective To compare the relations of social self-control and sensation seeking with substance use across samples of US and Russian adolescents. Methods Cross-sectional data were obtained from 362 tenth-graders from Ufa, Russia, and 965 tenth-graders from California. Results Lack of social self-control was significantly related with higher alcohol and hard drug use in the Russian sample and higher cigarette use in the US sample. Higher sensation-seeking showed significant associations with higher cigarette and alcohol use in the Russian sample and higher alcohol, marijuana, and hard drug use in the US sample. Conclusion As with US adolescents, prevention programs for Russian adolescents may also benefit from being tailored to higher sensation-seekers and including self-control skills training.

“…A disadvantage of this model, however, is that it includes only cases with data from both time points. We use ANCOVA as our primary method of analysis, as it generally offers greater power to detect differences between conditions (Janega et al 2004a;Venter et al 2002), but not always (Janega et al 2004b). Due to the complementary strengths and limitations of each model, however, we also report on whether the time by condition analysis confirmed the findings for our primary outcomes.…”

The Impact on Tobacco Use of Branded Youth Anti-tobacco Activities and Family Communications about Tobacco

In a randomized controlled trial, we evaluated the effect on tobacco use onset among middle school students of Family Communications (FC) activities designed to mobilize parental influences against tobacco use and Youth Anti-tobacco Activities (YAT) designed to market antitobacco norms to adolescents. We conducted a simple, twocondition experimental design in which 40 middle schools, with a prevalence of tobacco use at or above the Oregon median, received, by random assignment, either the intervention or no intervention. State, county, and local prevention coordinators around Oregon served as liaisons to schools. To generate interest, staff made presentations to these groups and distributed marketing packets at several conferences. Dependent variables were indices of smoking prevalence and use of smokeless tobacco (ST) in the prior month. Additionally, we created an intervention manual so that other communities could replicate this study. The findings suggest that efforts to influence parents to discourage their children's tobacco use and efforts to market an anti-tobacco perspective to teens are effective in preventing smoking. The impact of YAT is consistent with experimental and nonexperimental evaluations of media campaigns to influence young people not to smoke.
