Clinical Trial Summary

The primary objective of this study is to determine if online group CBT for PPD delivered by public health nurses is superior to postnatal care as usual in: a) acutely treating PPD, b) reducing relapse and recurrence, c) improving common comorbidities and complications of PPD including anxiety and the mother-infant relationship, and d) to determine if this treatment is cost-effective.

Description:

A prospective, 1-site, parallel group, RCT (1:1 ratio) in which outcome assessors and data analysts will be blinded to maternal treatment will be used to compare online PHN-delivered group CBT for PPD to postnatal care as usual. The primary objective of this study is to determine if online group CBT for PPD delivered by public health nurses is superior to postnatal care as usual in: a) acutely treating PPD, b) reducing relapse and recurrence, c) improving common comorbidities and complications of PPD including anxiety and the mother-infant relationship, and d) to determine if this treatment is cost-effective. Women in the treatment group will participate in a 9-week group CBT intervention for PPD delivered via Zoom by two public health nurses. 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.

Eligibility

Inclusion Criteria:

• Eligible women will be >18 years of age, understand and speak English (so that they can participate in the CBT group and complete study measures), have an EPDS score between of 10 or more and meet diagnostic criteria for current major depressive disorder on the Mini International Neuropsychiatric Interview-Plus (MINI-Plus). They will also all be within 12 months of delivering an infant.

Exclusion Criteria:

• In order to increase the relevance and generalizability of our findings, women can have psychiatric comorbidities with the exception of bipolar disorder, a current psychotic, substance or alcohol use disorder, or antisocial or borderline personality disorder.

The 9-week group CBT intervention for PPD delivered via Zoom by two public health nurses.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maternal Depressive Symptoms	Edinburgh Postnatal Depression Scale (EPDS): The EPDS is the 10-item gold standard measure of maternal depressive symptoms. A score >12 is consistent with PPD and changes in scores of 4 or more points are indicative of clinically significant improvement.	9 weeks
Secondary	Anxiety	Penn State Worry Questionnaire (PSWQ): The PSWQ is a 16-item self-report scale that taps generalized anxiety disorder, the most common comorbidity of PPD.	9 weeks
Secondary	Mother-Infant Bonding	Postpartum Bonding Questionnaire: The Postpartum Bonding Questionnaire is a 25 item maternal report scale that is designed to detect disorders of the mother-infant relationship on four subscales: bonding, rejection and anger, infant-focused anxiety, and incipient abuse.	9 weeks
Secondary	Social Support	The Social Provisions Scale: The SPS is a 24-item self-report measures of the degree to which an individual's social relationships provide support.	9 weeks
Secondary	Social Support	The Social Provisions Scale: The SPS is a 24-item self-report measures of the degree to which an individual's social relationships provide support.	6 months
Secondary	Relationship with Partner	Dyadic Adjustment Scale: a 32 item scale that assesses partner relationship on 4 subscales: dyadic consensus, affectional expression, dyadic satisfaction and dyadic cohesion.	6 months
Secondary	Relationship with Partner	Dyadic Adjustment Scale: a 32 item scale that assesses partner relationship on 4 subscales: dyadic consensus, affectional expression, dyadic satisfaction and dyadic cohesion.	9 weeks
Secondary	Infant Temperament	Infant Behavior Questionnaire-Revised (very short form): Temperament refers to the ways individuals think, behave, and react and is heavily influenced by the degree to which infants and toddlers can regulate their emotions. Factor analysis of the domains of temperament assessed by the IBQ-R (VSF) indicates that they are consistent with 3 broad dimensions of temperament: emotion regulation, negative affectivity, and extraversion. These subscales have demonstrated good internal consistency and inter-rater reliability between parents. Mothers and fathers will complete the IBQ-R on their infants immediately before treatment, right after treatment, and at 6 months afterward.	9 weeks

Secondary	Cost Effectiveness - costs	Cost-effectiveness will be measured using incremental cost per quality-adjusted life year ratio.; Costs: Canadian Community Health Survey and the Service Use and Resources Form. We will measure resources consumed over the trial period from the perspective of public health care payer. Corresponding unit costs will be calculated using provincial or other standard billing rates.	9 weeks
Secondary	Cost Effectiveness - QALY	Cost-effectiveness will be measured using incremental cost per quality-adjusted life year ratio.; Quality-Adjusted Life Year (QALY): The EQ-5D-5L is a utility-based health-related quality of life instrument consisting of five questions covering depression/anxiety, usual activities, self-care, pain/ discomfort, and mobility. Its validity in measuring the impact of depression is established. Its Canadian scoring algorithm will be used to convert the five responses to health utility at each measurement occasion.	9 weeks

It demonstrates very good agreement with the Structured Clinical Interview for DSM-IV and strong inter-rater reliability has been noted.; Major Depressive Disorder Module: Our primary outcome (recurrence) will be assessed at 6 months post-treatment, but in order to compare trajectories of recovery/recurrence/relapse, we will assess these outcomes at baseline, 9 weeks, and 6 months. Relapse will be assessed at 6 months post-CBT completion.; Our primary outcome for maternal depression using the MINI will be the proportion of women who meet MINI current MDD diagnostic criteria at 6 months.	6 months
