The trial was ended after one year due to the suspension of in-person research as a result of the COVID-19 pandemic. We have returned to the program development stage as we explore telehealth alternative options.

Brief Summary
Families who experience maternal mental illness and a variety of chronic stressors are currently underserved by the parenting programs. The investigators propose that impairments in maternal self-regulation, which result in unsupportive parenting, directly impact children's own self-regulation and neurobiology, leading to risk for intergenerational transmission of mental illness. The objective of this study is to develop and evaluate a program that is targeted at improving underlying self-regulatory mechanisms in both mothers with depression and their 3 to 5-year-old children. It is hypothesized that children exposed to maternal mental illness will have greater self-regulatory deficits across emotional and behavioural domains, compared to children not exposed to mental illness. The effects of maternal mental illness are expected to be compounded for children of mothers reporting a higher degree of chronic stressors, including poverty, housing instability, violence, and low social support. Further, it is hypothesized that taking a dual-generation intervention approach to addressing self-regulatory mechanisms underlying psychopathology at the level of the mother, child, and dyad (i.e. parenting interactions) will improve both maternal capacities and child outcomes. The objectives for this study are to 1) establish a better understanding of the self-regulatory processes that are altered in preschool-aged children exposed to maternal mental illness, and determine the mediating role of parenting behaviours, as well as the moderating impact of chronic stress exposure; and 2) develop and evaluate a novel dual-generation intervention for mothers with mental illness and their 3 to 5-year-old children based on existing gold-standard evidence-based approaches.

Outcome Measures
Primary Outcomes (3)
Change in Maternal Depression from pre-intervention to post-intervention - Beck Depression Inventory
21-item self-report inventory to measure symptoms and characteristics of depression. Participants respond to statements on a 0-3 likert scale. Higher scores indicate higher depression symptoms. The highest possible score is 60 and lowest possible score is 0.
The Beck Depression Inventory will be completed by participants at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time once again after the program is complete (approx. 20 weeks after Time 1).
Change in Maternal Emotion Regulation pre-intervention to post-intervention - Difficulties in Emotion Regulation Scale
18-item self-report questionnaire with 6 sub-categories to measure emotion regulation. Participants respond to items on a 5-point likert scale. Higher scores suggest more severe problems with emotion regulation. The highest possible score is 90 and the lowest possible score is 18.
The Difficulties in Emotion Regulation Scale will be completed by participants at Time 1 prior to the beginning of the BRIDGE Therapy Program and Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Change in Parenting Stress from pre-intervention to post-intervention - Parenting Stress Index (Short form)
36-item self-report measure filled out by parents to measure stress level within the context of parenting. Participants respond to items on a 5-point likert scale. There are 3 sub categories. Responses to each item in a sub-category are totalled and then the 3 subcategory scores are summed to represent a total stress score. Higher scores indicated higher levels of parenting stress. Normal scores fall within the 15th to 85th percentile, and scores above the 85th percentile represent clinically elevated levels of stress.
The Parenting Stress Index (short form) will be completed by participants at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Secondary Outcomes (2)
Change in the Child Behaviour Checklist from pre-intervention to post-intervention
The Child Behaviour Checklist will be completed by participants at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Change in Parental Sensitivity from pre-intervention to post-intervention
Parent-child interactions will be observed and video coded at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Other Outcomes (3)
Change in Parent Inhibitory Control from pre-intervention to post-intervention - Exploratory Outcome
Parent inhibitory control through the stop signal task will be measured at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Change in Child Cognitive Function from pre-intervention to post-intervention - Exploratory Outcome
Child cognitive function will be assessed at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Change in Child Stress System Reactivity and Recovery from pre-intervention to post-intervention - Exploratory Outcome
Child stress system reactivity and recovery will be measured at Time 1 prior to the beginning of the BRIDGE Therapy Program and at Time 2 once again after the program is complete (approx. 20 weeks after Time 1).
Study Arms (2)
BRIDGE Clinical Group
EXPERIMENTALThis group of mother-child dyads will have mothers who have been screened for and met diagnostic criteria for depression. Mothers in this group will participate in the 20-week group therapy and parent skills training intervention.
Baseline Comparison Group
NO INTERVENTIONThis group of mother-child dyads will not meet diagnostic criteria for depression and will serve as a comparison group for baseline measures. Dyads will be matched to the BRIDGE clinical group based on household income and child age.
Interventions
The BRIDGE Therapy Program is a novel structured form of therapy that incorporates key parenting concepts and related Dialectical Behavior Therapy (DBT) modules. The primary aim of the program is to promote self-regulation in the mother-child dyads. The program involves 20, once per week, scheduled group therapy sessions that last for 2 hours. There are two components of the program, the first is the DBT section, which will follow the DBT Skills Training Manual 2nd Edition and will target maternal mental health symptomology. The second section is the parent skill training materials, which have been designed to correspond to the 4 core DBT modules (Mindfulness, Emotion Regulation, Distress Tolerance, and Interpersonal Effectiveness) and to promote self-regulatory skill development and a positive parent-child relationship.
