Specific Aims
Informed by the Consolidated Framework for Implementation Research, a leading implementation science framework, this hybrid type III effectiveness implementation study will evaluate specific implementation strategies for MMBFM. Consistent with a hybrid type III study, there are two goals: (1) compare the clinical effectiveness of MMBFM supported by mental health clinician vs. peer coaches in a randomized trial of 470 pregnant women; and (2) compare the reach of MMBFM across OB clinics for two sets of implementation strategies to facilitate access to and initial engagement in MMBFM: patient facing strategies (PFS - direct outreach to women following prenatal visits via secure patient portal, email, text, or mail) vs. patient facing strategies combined with clinician facing strategies (PFS+CFS - Electronic Medical Record (EMR)-embedded prompts for OB providers, printed prescription pads for providers, flyers). A cluster randomized design will be used, randomizing 30 OB clinics across 4 health systems to either of these two implementation conditions, to assess their impact on reach. The investigators will address the following specific aims:
Aim 1: Compare the clinical effectiveness (i.e. engagement and symptom reduction) of MMBFM supported by clinician vs. peer coaches among women with a history of prior depressive episodes. Hypothesis 1: Coaching delivered by mental health clinicians vs. peers with lived experience will be associated with equivalent reductions in depressive symptoms at 6 months post-randomization.
Aim 2: Examine specific mechanisms of action for MMBFM participants receiving clinician vs. peer coaching. Hypothesis 2a: MMBFM participants receiving peer coaching will report less self-stigma and social isolation than those receiving clinician coaching, and MMBFM participants receiving clinician coaching will report less ruminative response to negative affect and greater decentering at 6 months post-randomization than those receiving peer coaching. Hypothesis 2b: Any difference between peer and clinician coaching in depression outcomes will be mediated by treatment-specific targets - at least partially via increased engagement.
Aim 3: Examine the effects of specific implementation strategies on reach of the MMBFM program. Hypothesis 3: Clinician facing implementation strategies (CFS) in combination with patient facing strategies (PFS) will lead to higher rates of reach than patient facing strategies alone.
Aim 4: Estimate the cost-effectiveness of MMBFM supported by clinician vs. peer coaches. Hypothesis 4: MMBFM will be more cost-effective when supported by peer vs. clinician coaches.
The trials of implementation strategies at the individual and clinic levels will be conducted at four health systems representing diversity in geographic location and in racial and ethnic membership: Kaiser Permanente Colorado, Southern California, and Georgia, and HealthPartners in Minnesota. These sites include 95 clinics and more than 400 obstetric clinicians (OB physicians, nurse practitioners, midwives, nurses), providing prenatal care for 53,000 women annually. The implementation trial for Aims 1 and 2 will recruit 470 women following prenatal care visits total across the four health systems and randomize them in equal numbers to participate in one of the two coaching arms for the MMBFM program, lasting 8 weeks. The clinic-level implementation trial (Aim 3) will involve a cluster randomized design in which 30 OB clinics will be recruited from the four health systems and randomized in equal numbers to either the PFS or PFS+CFS intervention arms, lasting 6 months. The individual- and clinic-level trials will be conducted in parallel.
The 8-session MMBFM program teaches mindfulness practice and cognitive behavioral skills to help reduce automatic, depressogenic modes of thoughts, emotions, and sensations. MMBFM is delivered in a mobile first digital format, accessible from desktop or mobile devices, and provided in an individually tailored manner that includes experiential practice, video-based vicarious learning, and didactic information.
