Summary

Perinatal depression and anxiety are common, serious, and frequently overlapping disorders that increase morbidity and mortality in new mothers (including suicide) and result in poor infant/child outcomes. Current therapies often fail to produce recovery or are poorly tolerated, and many pregnant women seek non-pharmacologic therapy or forgo treatment when non-pharmacologic options are not available. Expectant and new mothers who experience circadian rhythm dysregulation are at increased risk for perinatal depression. This Confirmatory Efficacy Clinical Trial of Non-Pharmacological Interventions for Mental Disorders R01 seeks to test whether a Personalized Integrated Chronotherapy (PIC) intervention can improve treatment outcomes for pregnant patients seeking outpatient treatment for depression, with or without anxiety. PIC is a multicomponent treatment consisting of bright light therapy, sleep phase advance, and sleep stabilization/restriction that targets the Research Domain Criteria (RDoC) constructs of circadian rhythms and sleep-wake behavior. To increase sample size and diversity and accelerate recruitment, this study will be performed at 4 sites that differ in clinical structure and that have piloted the PIC intervention. The study will enroll expectant mothers diagnosed with major depressive disorder during 3rd trimester of pregnancy. Participants will be randomized to either: (a) usual care (UC, n = 110) or (b) PIC+UC (n = 110). PIC+UC will have pregnancy and postpartum components and will be administered via a personalized approach tailored to optimize the intervention based on each patient's individual circadian and sleep timing. After a baseline assessment, PIC will be prescribed during 5 dedicated clinical visits: three during 3rd trimester of pregnancy and 2 in the postpartum period. UC will consist of medication and/or psychotherapy. UC will be quantified in both groups to evaluate differences between the PIC+UC and UC groups. Mood will be measured in both groups by blinded clinician interview and patient self-report. The safety profile of the PIC intervention will be assessed by evaluation of side effects/adverse events. Importantly, the study will also examine the target mechanisms by which PIC is hypothesized to work and test the mediation effects of the circadian targets on improvement in mood symptoms. Participants will wear wrist actigraphy/light monitors continuously during weeks 28-40 of pregnancy and postpartum weeks 2-6 to assess light exposure and to estimate sleep timing and duration. Circadian phase (measured with salivary dim light melatonin onset) will be measured at baseline during pregnancy (\~30 weeks' gestation), at 36 weeks' gestation, and at postpartum week 6. Exploratory aims will examine associations between infant sleep behavior and maternal circadian rhythms and factors relevant to future dissemination of PIC. If this intervention is effective, perinatal PIC could change clinical practice and have major public health impact due to the high prevalence of perinatal depression and anxiety, the negative effects of mood disorders on mothers and their children, and the need to provide effective, novel, non-pharmacologic therapies for women with perinatal mood disorders.

Detailed description

The purpose of this research study is to collect data on whether adding light therapy and a prescribed sleep schedule to usual treatment for depression can reduce depression and anxiety symptoms during pregnancy and the postpartum. The study is enrolling pregnant woman between the ages of 18 and 40 who have been diagnosed with depression and (possibly) anxiety. This study takes place from the 3rd trimester of pregnancy to 18 weeks postpartum. Women who take part in this study will be randomly assigned ("randomized") into one of the study treatment groups (1) the "usual care" group (UC); or (2) the group that receives bright light therapy and a prescribed sleep schedule, also called the "Personalized Integrated Chronotherapy" group (PIC). The usual care group will receive medications and/or talk therapy as decided by the woman and her doctor. Women in the integrated chronotherapy group will receive usual care (as above) and will also receive a bright light box to sit with every morning for up to 60 minutes as prescribed by the study doctor. Light will be delivered with a portable, broad-spectrum light box. Both groups will have their sleep and light levels monitored during 3rd trimester of pregnancy (weeks 28-40) and weeks 2-6 and 18 after the baby is born (postpartum weeks 2-6 and 18) Sleep monitoring takes place in the home using a small wrist activity monitor called an "actigraph." Participants will also be asked to provide three saliva sample sets over the course of the study to measure melatonin levels. In addition to the "Personalized Integrated Chronotherapy" study treatment that will supplement the clinical care as described above, participants will be asked to come in for research study visits.

Interventions

Type	Name	Description
BEHAVIORAL	Personalized Integrated Chronotherapy	Based on their baseline sleep-wake schedule and real-life constraints (work and other responsibilities), an initial sleep schedule is set that allows 7.5 hours of sleep and provides time for participants to sit in front of the morning bright light.
