Smart Steps: Embrace the Journey is a research‐based educational curriculum for stepfamily couples (“stepcouples”). The curriculum is designed to build couple strengths while addressing the unique challenges of repartnering with a child or children from a previous relationship. This study evaluated the effectiveness of this curriculum with 151 individuals in relationally less stable stepcouple relationships who either engaged in the Smart Steps curriculum (n = 97) or were part of the comparison group (n = 54). This study represents methodological and conceptual advances in the study of stepfamily programs with the use of a comparison group, a racially and economically diverse sample, and a relationally at‐risk population. Results indicated that those who participated in Smart Steps reported significant increases in individual empowerment, couple quality, family harmony, and parenting efficacy while these measures were unchanged for those who did not receive the program. Implications for future research and for practitioners are provided.
