Health And Response: Digital Markers for Outcomes in Perinatal Depression Treatment Study (HARMONY)

The purpose of this study is to determine if the addition of digital sensing data collected from phones and watches during the early stages of perinatal depression (PND) treatment can better predict treatment outcomes than using self-reported symptoms alone.STAND for PND: The UCLA Depression Grand Challenge (DGC) has previously developed a technology-assisted, scalable therapy system called STAND (Screening and Treatment for ANxiety and Depression) for perinatal depression (PND) and has demonstrated in an initial randomized clinical trial that this treatment intervention to be as effective as psychiatrist delivered care for PND. In this study, the investigators will administer STAND for PND for up to 12 weeks as part of study participation. There will be no comparison between our treatment intervention and a treatment as usual condition, as this is not a trial of efficacy. In the STAND for PND treatment model, women with moderate symptoms will be routed to coach-guided, digital cognitive behavioral therapy (CBT) tailored to PND, which has been demonstrated to be an effective treatment approach for PND. Women with severe depression or suicidality will be routed to clinician delivered CBT, with pharmacotherapy as needed, with both CBT and pharmacotherapy demonstrated to be effective treatment approaches for PND. Symptoms will be regularly monitored throughout the intervention period. Digital Sensing in Depression: The DGC also has substantial experience in large-scale longitudinal digital sensing studies, and experience identifying associations between self-report or clinical ratings of depressive symptoms and digital sensing features, including in pregnant and postpartum women. Digital Sensing in a STAND for PND study: In our previous STAND for PND study, the investigators did not include digital sensing. In this next phase of our research program, the investigators will collect digital sensing data from phones and watches during the first four weeks of study participation. The investigators will enroll up to 250 women during their last trimester or who are in the postpartum period to participate in the 12-week study, which includes treatment provided through the STAND for PND program of care and during which the investigators will obtain 4-weeks of digital sensing data.The investigators will be testing whether behaviors measures through digital sensing (i.e., digital features) in combination with self-reported depression symptoms will better predict treatment outcomes than the self-reported depression symptoms alone. The investigators are testing the hypothesis that prospective longitudinal assessments using digital devices will enhance our ability to predict outcomes of STAND-PND.This project is part of a larger program of research that aims to improve clinical decision-making for PND by establishing a clinical care model for PND that fully integrates digital sensing with digital therapy. An additional objective of this program of research is to target low-income mothers from populations that have had limited access to mental healthcare, given that this population is particularly vulnerable to the impact of PND.
