ObjectiveThe goal was to determine if time spent in specific Healthy Marriage Initiative program components (relationship education courses, supplemental activities, and family support services) was associated with future relationship satisfaction and to examine if effects differed depending on the degree of economic disadvantage.BackgroundHealthy Marriage Initiatives (HMI) generally have small, short‐term positive effects on relationship outcomes. It remains unclear, however, which programming components are responsible for those effects and for whom programming is most effective.MethodUsing two waves of data from over 2,000 lower‐income couples in the Supporting Healthy Marriages study, we conducted path models and a multigroup model to address our research aims.ResultsTime spent in family support services was the only component positively associated with future satisfaction, controlling for the influence of other program components, initial relationship satisfaction, and expectations of the program's effectiveness. Economic disadvantage did not moderate any of these associations.ConclusionResults suggest that many HMI programs may potentially be beneficial to relationship functioning because of the provision of supplementary support services that partially aim to alleviate external stressors and provide personalized assistance to families.ImplicationsPractitioners should not only consider how relationship education programming may influence intimate bonds, but also how complementary programs may also factor into program efficacy.
