This paper describes a preventive intervention trial called EARLY ALLIANCE which is aimed at reducing risk for three adverse outcomes in childhood and adolescence: conduct problems, substance abuse, and school failure. The structure of the prevention trial is unique because two linked designs are being implemented concurrently. The primary design focuses on children at elevated risk for adverse outcomes, and compares a targeted, multicontextual preventive intervention with family, classroom, peer relational, and academic components to a universal, schoolwide preventive intervention that emphasizes peaceful conflict management and serves as a "usual care" control condition. The secondary design focuses on children at lower risk for adverse outcomes and compares a universally administered classroom program to the control condition. The paper describes the theoretical foundation for EARLY ALLIANCE, the goals of the prevention trial, the rationale for design choices, and the methods employed. |
