The purpose of this presentation is to share findings from the evaluation of the state of Nebraska's SIG. The objectives of the present study are to (1) examine whether substance use or substance-related consequences decreased in communities that implemented the SIG programs compared to communities that did not implement the SIG, (2) to investigate the influence of program characteristics (i.e., fidelity, dosage) on aggregated substance use outcomes; and (3) to investigate the influence of coalition characteristics (i.e., leadership, satisfaction) on substance use aggregate level outcomes.
Longitudinal Growth Modeling (LGM) will be applied to three waves of data collected in 2003, 2005, and 2007 to determine the overall impact of the SIG initiative. Results from latent profile analysis (LPA) will also be presented to identify key underlying characteristics of the most effective community coalitions. Findings will provide important insight regarding characteristics associated with program effectiveness in real world settings and will provide a critical test of federal policies requiring implementation of evidence-based strategies via community coalitions.
Learning Objectives:
This presentation attempts to achieve the following learning objectives:
(1) To demonstrate the impact of evidence-based strategies (individual and environmental) on adolescent substance use;
(2) To demonstrate the utility of advanced analytic techniques such as LGM in evaluating quasi-experimental designs; and
(3) To demonstrate the importance of coalition characteristics in explaining community differences
