This article describes an evidence-based preventive group intervention, Incredible Years Parent Training Program (IY). Decades of research have shown that IY strengthens parent and child competencies and in turn reduces child risks for developing conduct problems and other negative life outcomes. The purpose of this article is to examine IY through a resilience lens and highlight how it capitalizes on group process mechanisms to serve as a model preventive group intervention. Future directions and implications for research, practice, and training are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
