School-based prevention programs can positively impact a range of social, emotional, and behavioral outcomes. Yet the current climate of accountability pressures schools to restrict activities that are not perceived as part of the core curriculum. Building on models from public health and prevention science, we describe an integrated approach to school-based prevention. These models leverage the most effective structural and content components of social-emotional and behavioral health preventive interventions. Integrated interventions are expected to have additive and synergistic effects which result in greater impacts on multiple student outcomes. Integrated programs are also expected to be more efficient to deliver, easier to implement with high quality and integrity, and more sustainable. We provide a detailed example of the process through which the PAX-Good Behavior Game and the Promoting Alternative Thinking Strategies (PATHS) curriculum were integrated into the PATHS to PAX model. Implications for future research are proposed. [This paper was published in "Psychology in the Schools" v47 n1 p71-88 2010.]
