“…To test for a main effect of implementer type on fidelity and immediate student outcomes, we used a mixed-linear model (Murray & Hannan, 1990) as implemented in the SAS statistical package® (SAS Institute, 2004). In each of the models, implementer type (regular classroom teacher or program specialist) was considered as a fixed effect and class nested within school was considered as a random factor.…”

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 selfcontrol. 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.

“…Methods of analysis that account for intact social groups as the unit of randomization and the interdependence of data from members of these social groups have been developed for examining the effects of community-level prevention trials. [27][28][29] The analyses of response data were based on the use of housing developments as the unit of analysis and a mixed-model generalized linear model approach for hypothesis testing. 30 The model describing response Y ijklm of individual m within development l(k) in city k and condition i at survey time point j is as follows:…”

Objectives. Women in impoverished inner-city neighborhoods are at high risk for contracting HIV. A randomized, multisite community-level HIV prevention trial was undertaken with women living in 18 low-income housing developments in 5 US cities.Methods. Baseline and 12-month follow-up population risk characteristics were assessed by surveying 690 women at both time points. In the 9 intervention condition housing developments, a community-level intervention was undertaken that included HIV risk reduction workshops and community HIV prevention events implemented by women who were popular opinion leaders among their peers.Results. The proportion of women in the intervention developments who had any unprotected intercourse in the past 2 months declined from 50% to 37.6%, and the percentage of women's acts of intercourse protected by condoms increased from 30.2% to 47.2%. Among women exposed to intervention activities, the mean frequency of unprotected acts of intercourse in the past 2 months tended to be lower at follow-up (mean = 4.0) than at baseline (mean = 6.0). These changes were corroborated by changes in other risk indicators.Conclusions. 3 African American women are 16 times more likely to be diagnosed with AIDS than White women and, among women of childbearing age, have HIV seroprevalence rates 6 to 15 times higher than those of nonminority women.

“…Sample size calculations for .90 statistical power were based on methods specifically focused on nested cohort designs (Koepsell T, 1998, Murray andHannan, 1990). Based on these calculations, 16 PAT programs from rural, southeast Missouri were identified and recruited into the study.…”

Objective-The High 5 for Preschool Kids (H5-KIDS) program tested the effectiveness of a home based intervention to teach parents how to ensure a positive fruit-vegetable (FV) environment for their preschool child, and to examine whether changes in parent behavior were associated with improvements in child intake. Results-When compared to control parents, H5-KIDS parents reported an increase in FV servings (MN=.20, p=.05), knowledge and availability of FV within the home (p=.01), and decreased their use of noncoercive feeding practices (p=.02). Among preschoolers, FV servings increased in normal weight (MN=.35, p=.02) but not overweight children (MN=-.10, p=.48), relative to controls. Parent's change in FV servings was a significant predictor of child's change in FV in the H5-KIDS group (p=.001). Methods Conclusion-H5-KIDSsuggests the need for, and promise of, early home intervention for childhood obesity prevention. It demonstrates the importance of participatory approaches in developing externally valid interventions, with the potential for dissemination across national parent education programs as a means for improving the intake of parents and young children.
