The study assesses the association between points of course execution and alter in adolescent drug use behavior in the Midwestern Prevention Project (MPP), a school- and community based program for drug abuse prevention. Trained teachers implement the program with transition year students. Realization was calculated by teacher self-report and authenticated by research staff reports. Drug use among adolescents was measured by self-report measure of breath snuff consumption was used to increase the accuracy of drug use self-report. Regression analyses were used to evaluate adherence; exposure, or amount of implementation; and reinvention. Results showed that all schools assigned to the program condition adhered to the research by implementing the program.
The chapter outlines a strategy for assessing the long-term effects of drug abuse prevention interventions in replicable studies. It comprises of a theory-driven data compilation and investigation approach that involves the need to link proximal involvement outputs to more distal outcomes desired. The approach also requires prospective longitudinal follow-up studies in which complete panels of subjects who vary with respect to the levels of key predictor constructs are followed up through the period of their highest risk for drug use.
The chapter introduces the reader to a latent transition analysis (LTA) and demonstrates the usefulness of the technique in investigating the prevention of alcohol. The authors begin with a description of the LTA model, both in conceptual and statistical terms. Then they present the results of a study using LTA to model drug use among adolescents who participated in a survey conducted as part of the test Adolescent Alcohol Prevention (AAPT, Graham, Rohrbach, Hansen, Flay, and Johnson, 1989).
The chapter discusses the role of subject attrition in substance abuse prevention research. Attrition may affect the validity of experimental comparisons and may limit the extent to which findings can be generalized to adolescents at highest risk. The authors examine concerns about subject attrition, present methods for analyzing attrition in evaluations of prevention programs, and make recommendations for minimizing the extent and impact of attrition in such evaluations.
The author considers the impact of early childhood and preadolescent socialization experiences on adolescent drug use from a developmental perspective. She first reviews the processes defining normal adolescent development and then presents findings on the preadolescent phase of the Family Socialization and Developmental Competence Project.
