NCT05772897

Brief Summary

The goal of this longitudinal study is to study the effects of a parenting skills group (Circle of Security Parenting, aka COSP) in mothers with postpartum depression. The main questions it aims to answer are:

  • Will changes in methylation of the OXTR rs53576 be apparent in mother and/or infant after having gone through the 8-week COSP program?
  • Will COSP participation be associated with improved symptoms of postpartum depression (over and above standard care), attachment style, and relational characteristics of the mother-infant dyad?
  • Will COSP participation be associated with changes in social behavior in the infant, and if so, do they persist throughout childhood? Participants will
  • Participate in an 8-week COSP program delivered remotely via Zoom.
  • Provide buccal swabs (mother and infant) to assess changes in methylation of OXTR rs53576 pre- versus post-intervention.
  • Complete a series of assessment questionnaires delivered remotely.
  • Videotape a play-based assessment in their home.
  • Receive infant developmental testing Researchers will compare characteristics of waitlist controls to those participating in the COSP program at the mid-way point of the program to see if the two groups differ.

Outcome Measures

Primary Outcomes (4)

  • Change in methylation of OXTR receptor gene rs53576

    Buccal swabs from mother and infant

    Time1 (baseline), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention) Time7 (average 4.5 years post-intervention)

  • Changes in Beck Depression Inventory, Second Edition (BDI-II) Score

    The BDI-II is a brief, self-report inventory designed to measure the severity of depression symptomatology for ages 13-80 years old and takes approximately 5 minutes to complete. The BDI-II is comprised of 21 items. Each item is scored on a scale of 0 to 3, with a total score range of 0-63. Total score of \<14 indicates minimal range, 14-19 indicates mild severity, 20-28 indicates moderate severity, and 29-63 indicates a score in the severe range. Higher scores indicate greater levels of depression.

    Time1 (baseline), Time2 (1 week pre-intervention), Time3 (week 5 of intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention), Time7 (average 4.5 years post-intervention)

  • Changes Postpartum Depression Screening Scale (PDSS) Score

    The PDSS is a 35-item self-report measure helps clinicians identify mothers suffering from postpartum depression. It takes about 5-10 minutes to complete and is written at a third-grade reading level. Mothers respond using a 5-point scale ranging from "strongly disagree" to "strongly agree" and yields an overall severity score. A higher score indicates more severe depression.

    Time1 (baseline), Time2 (1 week pre-intervention), Time3 (week 5 of intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention)

  • Changes in Dyadic Adjustment Scale (DAS) Score

    A 32-item measure of relationship quality. The scale is divided into 4 subscales: (1) Dyadic Consensus - degree to which respondent agrees with partner (2) Dyadic Satisfaction -- degree to which respondent feels satisfied with partner (3) Dyadic Cohesion -degree to which respondent and partner participate in activities together (4) Affectional Expression -degree to which respondent agrees with partner regarding emotional affection. Scores range from 0-151, with higher scores being indicative of more positive dyadic adjustment and lower distress level.

    Time1 (baseline), Time2 (1 week pre-intervention), Time3 (week 5 of intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention), Time7 (average 4.5 years post-intervention)

Secondary Outcomes (7)

  • Changes in Denver Maternal Stress Assessment Score

    Time1 (baseline), Time2 (1 week pre-intervention), Time3 (week 5 of intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention), Time7 (average 4.5 years post-intervention)

  • Changes in MacArthur Short Form Vocabulary Checklist Score (child)

    Time1 (baseline), Time5 (6 months post-intervention), Time6 (12 months post-intervention)

  • Changes in Maternal Postnatal Attachment Scale (MPAS) Score

    Time1 (baseline), Time2 (1 week pre-intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention)

  • Changes in The Multidimensional Scale of Perceived Social Support (MSPSS) Score

    Time1 (baseline), Time2 (1 week pre-intervention), Time3 (week 5 of intervention), Time4 (1 week post-intervention), Time5 (6 months post-intervention), Time6 (12 months post-intervention), Time7 (average 4.5 years post-intervention)

  • Changes in Carey Infant Temperament Questionnaire (ITQ) Score

    Time1 (baseline), Time5 (6 months post-intervention), Time6 (12 months post-intervention), Time7 (average 4.5 years post-intervention)

  • +2 more secondary outcomes

Study Arms (2)

Circle of Security Parenting (COSP) group

EXPERIMENTAL

This group of mothers will be assigned to begin the parenting skills intervention (COSP) group soon after enrollment, and data collection (developmental testing, buccal swabs, play-based assessment, questionnaires) will proceed as planned. COSP groups will be conducted remotely via Zoom.

Behavioral: Circle of Security Parenting program

Waitlist Control Group

NO INTERVENTION

This group of mothers will be assigned to a waitlist control group and will be scheduled to begin the parenting skills group at a later time. In order to serve as a no-intervention control, they will be administered assessments while on the waiting list. These assessments will be given concurrently with mid-point assessment of the intervention group.

Interventions

The Circle of Security Parenting (COSP) program is an 8- week group parenting course that was designed using decades of attachment research to foster a secure attachment by teaching parents to read and respond to infant cues, and to recognize the interplay between their own psychological and emotional experiences and the emotional regulation of their infants. The COSP program provides parents with relationship tools and techniques for understanding their children's needs in new ways that provide lasting security for the child and more satisfaction for the parent. There are two major themes in the program: 1) teaching parents how to read their children's behavior and use it as a guide for meeting their needs and 2) helping parents to understand how their own early attachment relationships have influenced them as a person, and how those influences show up in their parenting and impact their ability to help regulate their child and respond to their needs.
