Adolescent-focused marriage education is a relatively uncharted research area. Using a quasi-experimental design, this study examined the effectiveness of an adapted version of the curriculum entitled, "Love U2: Increasing Your Relationship Smarts" with an economically, geographically, and racially diverse sample of 340 high school students. Findings suggest that participants showed increases in 5 dimensions of their relationship knowledge, including their ability to identify unhealthy relationship patterns. Participants also had more realistic beliefs about relationships/marriages and reported lower levels of verbal aggression use at postprogram compared to controls. Moreover, these findings existed across race, household income, and family structure type, with all participating students benefiting in similar ways. Implications for future programming and research are discussed.
