Brief summary

Background: Children in out-of-home care constitute a vulnerable population often experiencing mental health challenges related to early adversity and placement disruptions. The Circle of Security Parenting® (COS-P) program is an attachment-based intervention designed to enhance carer sensitivity and reflective functioning, ultimately improving the quality of carer-child relationships. Methods This study protocol follows a mixed-methods randomized controlled trial evaluating the effectiveness of the COS-P program for foster carers in France. A total of 70 foster carers will be randomly assigned to either the intervention group (receiving COS-P in addition to Treatment as Usual) or the waitlist control group (receiving Treatment as Usual only). Quantitative measures, including the Caregiving Composite Questionnaire, Parenting Stress Index, and the Marschak Interaction Method, will be administered at baseline and at follow-up). Qualitative data will be collected through focus groups with foster carers and COS-P facilitators, and through self-confrontation interviews with a subset of foster carers. Discussion: This study is the first to evaluate COS-P for foster carers in France. Findings will provide valuable insights into the program's effectiveness in improving carer-child relationships and foster carer well-being, ultimately contributing to better outcomes for children in out-of-home care. The study will also explore potential moderators of treatment outcome and shed light on the subjective experiences of participants.

Interventions

BEHAVIORALCircle of security Parenting (COS-P)

The Circle of Security Parenting® (COS-P) program is an attachment-based intervention designed to enhance caregiver sensitivity, parental reflective functioning, and the quality of the child's attachment to their caregiver. This manualized intervention, with both educational and therapeutic components, empowers caregivers to better understand and respond to their child's needs, fostering secure attachment (22).

BEHAVIORALTraitement as usual (TAU)

TAU typically involves home visits, educational and psychological support for foster carers and/or children in placement, and efforts to support and monitor contact between children and their birth families.

Design outcomes

Primary

MeasureTime frameDescription
Caregiving composite questionnaire (CCQ)at baseline and at 3 month f/uThe CCQ is a 43-item self-report measure specifically designed to assess parent capacities targeted by the COS-P program, namely: parental mentalizing, parenting self-efficacy, and parent perceptions of the child. It combines six subscales and one single item drawn from previously validated measures, retaining the original response formats and scoring procedures for each subscale. The CCQ has demonstrated good reliability and validity in a pilot sample of parents and is being used in the current study to assess the impact of COS-P on these key parenting capacities.
Parent Development Interview-RevisedAt baseline and at 3-month f/uThis semi-structured interview consists of 31 questions, administered in approximately one hour, covering four domains: (a) perception of the child, (b) perception of the relationship, (c) parental affective experience, and (d) separation experiences.

Secondary

MeasureTime frameDescription
Parenting Stress Index - IV - Short Form (PSI)At baseline and 3-month f/uThis 36-item questionnaire includes three subscales: Parental Distress (PD), Parent-Child Dysfunctional Interaction (P-CDI), and Difficult Child (DC). The 12 items of the P-CDI subscale will be used to assess foster carers' perceptions of their relationship with the child in their care, using a 5-point Likert scale.
Marschak Interaction Method (MIM)At baseline and 3-month f/uThis structured assessment tool is based on attachment and mentalization theories and involves a series of age-appropriate tasks completed by the foster carer and child together. The MIM assesses four dimensions of interaction: Structure, Engagement, Nurture, and Challenge. Interaction recordings will be coded using the Dyadic Emotional Interaction Style (D-EIS), developed in Finland and used internationally.
