Approximately 15% of women in the United States develop postpartum depression (PPD) [1]. The United States Preventive Services Task Force (USPSTF) recommends that women at risk for PPD participate in a program such as Mothers and Babies (MB), an in-person cognitive behavioral therapy (CBT)–based curriculum that prevents PPD [2]. Because smartphone app–provided CBT can reduce PPD symptoms and expand the reach of CBT programs [3], we used individual in-depth interviews with perinatal women to develop a novel app, MBapp, that adapts MB to a digital format [4].

During the interviews that guided app development, study participants noted that MBapp would be useful for their partner or would benefit their relationship with their partner. To explore MBapp’s potential utility as a dyadic intervention, we conducted a qualitative analysis of emergent data obtained during thematic analysis from interviews that guided MB’s adaptation into MBapp.

As previously reported [4,5], the 25 interviewees were racially and ethnically diverse, with half primiparous, (n=13, 52%), half Spanish-speaking, (n=12, 48%), and half pregnant (n=13, 52%) (Table 1). Of the 25 women, 5 independently expressed, without any explicit prompting, that they saw value in providing MBapp to their partner. In this subgroup, 3 of 5 were Spanish-speaking, 2 of 5 were primiparous, and 3 of 5 were post partum.

Each of these 5 participants mentioned their interest in sharing MBapp with their partner when prompted to suggest ways to enhance the app’s usefulness for perinatal women. The 5 women stated that providing MBapp to a partner would make it more effective as both a perinatal psychoeducational tool and a CBT-based program (Table 2). Some endorsed that MBapp could teach their partners how to improve communication and provide infant care, helping them be a more supportive partner. Others noted that MBapp could help their partners recognize the interplay between relationship dynamics, maternal isolation, and PPD symptoms. Each of these 5 participants was surprised that MBapp was planned to be delivered exclusively to the pregnant person.

This study presents emergent qualitative data from diverse perinatal women whose feedback was used to optimize MBapp, a novel app-based CBT program. Without prompting, 5 of 25 participants noted that MBapp would be more useful for them if it were also provided to their partners. Had the interview specifically queried about perceptions of partner use and involvement, the proportion of participants who reported MBapp would be more useful as a dyadic than a stand-alone intervention may have been higher. These emergent data align with the well-known bidirectional association between maternal and paternal perinatal mental health symptoms [6,7]. Though a small study has proven the feasibility of delivering in-person MB to both parents simultaneously [8], the feasibility and effectiveness of delivering MBapp—or other USPSTF-recommended psychotherapy [2]—as a digital dyadic intervention to prevent PPD has yet to be explored. Study strengths include a diverse study population and interviews conducted in English or Spanish. Furthermore, the study population can be considered sufficiently sampled per qualitative methodology principles [9]. Study limitations include exclusive recruitment at one obstetric clinic. Expanding data collection can assess whether these findings resonate in other populations. In addition, because the interviews were not intended to discuss partner status—much less partner support—the proportion of participants with partners (and supportive or unsupportive partners) is unknown. Lastly, emergent themes on partners were not identified until the data were analyzed; thus, thematic saturation was not achieved. In summary, this qualitative analysis demonstrates that an evidence-based maternal PPD-prevention intervention may be more useful if delivered simultaneously to both parents, potentially by being an upstream mediator of maternal PPD, as per dyadic coping theory [10]. Our results call for additional research examining not just the feasibility and effectiveness but the mechanisms of effectiveness of digital dyadic or stand-alone partner PPD prevention interventions.
