The literature on engaging families in prevention programs is informed by the Health Beliefs Model (HBM), Theory of Reasoned Action (TRA), and Family Systems theory. Although useful, these frameworks have not facilitated the development of prevention-based practice strategies that recognize different levels of prevention (i.e., universal, selective, and indicated). This article contributes to the literature on parent engagement by (a) summarizing the research on factors that affect parent engagement, (b) proposing an integrated model for engaging parents that incorporates the various levels of prevention, and (c) suggesting engagement strategies for universal, selective, and indicated prevention programs within this integrated model.
