Not surprisingly, incarceration's extreme separation and stress have significant negative effects on romantic relationships. Unfortunately, few programs have been developed to improve jailed individuals' romantic relationship with their non-incarcerated partner. The present study investigated the effectiveness of the individual version of the digital OurRelationship program for incarcerated individuals. The current study is a program evaluation of services provided by PayTel Inc. (a provider of eLearning and communication devices in US jails) between June 2020 and November 2021. Of the 5411 individuals in a romantic relationship who started the program, 3034 completed it. Following completion of the program, 78% reported feeling "Mostly" or "Very Satisfied" with the program, and 77% reported "Slight" to "Strong" agreement that their relationship benefited from the program. Individuals' relationship confidence (d = 0.36) and relationship knowledge (d = 0.33) significantly improved during the program. Women and Latino/Hispanic and Asian/PI individuals experienced the largest pre-post gains in relationship functioning. Furthermore, racial/ethnic minority groups tended to report higher satisfaction with the program. Overall, the high rates of program satisfaction and significant pre-post changes-combined with their reduced barriers to dissemination-support the delivery of digital relationship programs for jailed individuals interested in strengthening their relationship.
