PMADs are prevalent among pregnant people and their partners [Despite pregnant people's eligibility in the study, many couples were not enrolled due to a non-responsive partner. Partners enrolled in the study responded less often to surveys than pregnant people, and only partners indicated never having engaged with eMB during the trial. Similarly, participants did not complete the lessons as directed and thus did not receive the total treatment dose. Given these results, future online studies may retain participants through a highly engaged intervention team and examine different approaches to engaging the perinatal unit to encourage treatment adherence and program completion [Participants' satisfaction with eMB suggests a successful course translation from in-person programming to online delivery. The eMB course seemed to increase emotional awareness and connectivity and the potential to buffer risks associated with anxiety and depression. Despite high satisfaction scores, fewer partner participants engaged with the programming than pregnant people. This study's feasibility findings suggest the need for improving intervention adherence, a similar result as in other studies [Symptom severity for anxiety and depression decreased in favor of the intervention group and statistically significantly reduced anxiety symptoms between groups for pregnant people at the study midpoint. Previous CBT-based online interventions for pregnant people found significant reductions in anxiety or depression at the study conclusion [Given the relatively small change in partners' mood and anxiety scores compared to pregnant people in this study, future research warrants exploration of why pregnant people had significant decreases in anxiety symptoms. In contrast, the partner's changes were less dramatic. Evidence suggests relational factors [More research on engaging couples in PMAD interventions is warranted, and findings from this study offer suggestions for improvement that may increase eMB engagement. Clinicians, behavioral health professionals, and researchers can partner with health departments, federally qualified health centers, or birth centers to examine using eMB [
