Healthy romantic relationships are associated with a multitude of positive physical and mental health outcomes. Conversely, low relationship quality and relationship dissolution are associated with risk for poor health outcomes. Accordingly, numerous studies investigate ways to preserve healthy relationships through the use of preventative relationship education interventions, many of which improve relationship outcomes. However, evidence for the efficacy and effectiveness of these interventions is somewhat mixed, and promising interventions often fail to reach at-risk populations due to high participant burden. There is a movement within clinical psychology to create easily accessible, targeted therapy protocols in order to increase the broad availability of these evidence-based interventions. The current study aimed to replicate and extend the Marriage Hack (MH), a brief, evidence-based preventative relationship intervention designed to stabilize the natural decline in relationship quality over time. This study addressed four specific aims designed to: 1) examine the efficacy of the MH intervention using an abbreviated protocol; 2) extend the original MH intervention by investigating theory-based mechanisms of change and assessing individual health outcomes; 3) explore how theory-based mechanisms change over time; and, 4) evaluate the relationship between within-person and between-person variance in process variables and outcome measures. Seventy-eight (N = 78) couples were randomized to the 4-week MH protocol (n = 41) or control condition (n = 37). Results demonstrated men in the intervention group exhibited 1) greater improvements in relationship satisfaction and 2) decreases in both anxiety and depression compared to men in the control group. This study did not replicate the findings of the original MH for additional outcome variables and process variables for men or women. No support was found for mediating effects of additional theory-based mechanisms of change on outcome measures. However, exploratory intensive longitudinal analyses revealed noteworthy relationships between within-person and between-person variance in process variables and treatment outcomes. Research recommendations to further improve preventative relationship interventions and clinical implications of the current findings are discussed.
