Brief Summary

Postpartum depression (PPD) affects over 14,000 women in Ontario each year and can have profound effects on mothers, their children, and their families. The cost of one case of PPD exceeds $150,000, a significant proportion of which is related to its impact on offspring. However, difficulties accessing preferred treatments (e.g., psychotherapy) result in fewer than 15% of women receiving care. While Public Health Units have played an important role in PPD detection in Ontario, Public Health Nurses (PHNs) currently lack the skills to deliver evidence-based treatment to women. Cognitive Behavioural Therapy (CBT) delivered in group format is effective for treating depression in the perinatal period, and as PHNs are often the first point of contact for women experiencing PPD, with specialized training it is likely that they can deliver high-quality CBT.

The primary objective of this study is to determine if PHNs can be trained to deliver group Cognitive Behavioral Therapy (CBT) to acutely treat PPD, reduce relapse and recurrence, improve mother-infant attachment and parenting and optimize infant emotional functioning.

Detailed Description

In addition to its effects on maternal health, PPD can adversely affect mother-infant attachment, parenting, and the development and health of her children. The negative effects of PPD on offspring can include an increased risk of insecure attachment, poorer cognitive, language, and behavioral development, as well as an increased risk of emotion regulatory problems. To determine if PHNs can effectively deliver group CBT for PPD that is superior to postnatal care as usual, the investigators will proceed with a randomized controlled trial (RCT). Women in the treatment group will attend a 9-week group CBT intervention delivered by trained PHNs. Those in the control group will receive standard postnatal care.

This RCT will compare the effects of group CBT to postnatal care as usual on maternal depression, anxiety, mother-infant attachment, parenting, healthcare utilization and social support, as well as infant development, emotion regulation, and healthcare utilization

Arm && Interventions

Group	Intervention	Description
Treatment Group	Group Cognitive Behavioral Therapy	Group CBT for PPD. Women in the treatment group will attend a 9-week group CBT intervention for PPD. This intervention was developed at the Women's Health Concerns Clinic (WHCC) at St. Joseph's Healthcare Hamilton. It was designed to be brief, simple, and applicable to women in community settings. It consists of 9 weekly 2-hour sessions where core CBT skills are learned and practiced, and a new psychoeducational topic is introduced and discussed by women each week.
Control Group	Postnatal Care As Usual	Standard Care. The usual care group will receive standard care from their family physician and midwife or obstetrician. They will also be made aware of the perinatal programming available to them through Niagara Region Public Health. Women and family physicians will also receive a copy of the Canadian Practice Guidelines for the Treatment of Perinatal Depression.

Primary Outcome Measures

Name	Time	Method
Edinburgh Postnatal Depression Scale (EPDS)	6 months	The EPDS will be used to assess maternal depression. A score of \>12 is consistent with PPD and changes in scores \>4 are indicative of clinically significant improvement.
Mini International Neuropsychiatric Interview - Current Major Depressive Disorder	6 months	Used to assess maternal depression.

Secondary Outcome Measures

Name	Time	Method
Ages and Stages Questionnaires - Third Edition	6 months	Assesses infant communication, motor and socioemotional development using age-specific scales.
Salivary Cortisol	6 months	Used to assess stress reactivity and emotion regulation. Three samples will be taken during each assessment: 10-15 minutes after the beginning of the assessment, 15-20 minutes after the face-to-face still face task and at the end of the visit.
Corticolimbic Brain Function: EEG-Based Frontal Lobe Asymmetry (via MUSE Headband)	6 months	Corticolimbic brain activity at the scalp will be assessed using electroencephalography (EEG). Greater left frontal asymmetry (greater activity in the left frontal hemisphere) is thought to reflect positive emotionality and indicate a greater tendency to engage in more adaptive emotion regulation strategies. However greater right activity reflects a tendency to engage in withdrawn behaviours and negative emotionality.
Penn State Worry Questionnaire (PSWQ)	6 months	Maternal Anxiety will be assessed using the Penn State Worry Questionnaire.
Face-to-Face Still Face Paradigm	6 months	Experimental task used to assess emotion regulation in infants
Maternal & Infant Healthcare Utilization	6 months	Adopted form the Canadian Community Health Survey to track use of healthcare services.
Infant Behaviour Questionnaire-Revised	6 months	This scale assesses infant temperament
Parasympathetic Nervous System Functioning: Heart Rate Variability	6 months	Used to asses the flexibility of the central and peripheral nervous system to handle stress.
Parent-Child Early Relational Assessment	6 months	Used to measure the quality of affect and behavior in parent-child interactions.
Social Provisions Scale	6 months	Used to measure the degree to which mothers' social relationships provide support
Postpartum Bonding Questionnaire	6 months	Used to detect disorders of the mother-infant relationship.
