LAUSR

Low-income couples are at increased risk for relationship instability and divorce. In response, online relationship education programs such as ePREP and OurRelationship have been developed to more easily reach this population. A previous trial indicated that these programs promote relationship functioning (Doss et al., 2020) and individual well-being (Roddy et al., 2020a). However, given that these effects were notably larger than previous studies of in-person relationship education and approached effect sizes observed in couple therapy, it is possible that the magnitude of these effects was somewhat spurious; therefore, these findings need replication. The current manuscript seeks to replicate these programs' previous effects on relationship functioning and determine whether these effects are stable. Using a sample of 671 low-income couples seeking relationship help (N = 1337 individuals) and Bayesian estimation, the current study replicated previous findings that the OurRelationship and ePREP programs offered with four coaching calls produced reliable improvements in relationship functioning relative to a 6-month waitlist control group. There were no statistically reliable differences between the two active interventions. Bayesian analyses indicated that the effects of the two online programs were larger than the average effects of in-person relationship education for low-income couples reported in previous studies, roughly equivalent to efficacy studies of in-person relationship education reported in previous studies, smaller than those that resulted from the OurRelationship program delivered to distressed couples without an income requirement and smaller than couple therapy.
