Attachment and Biobehavioral Catch-up: An evidence-based intervention for vulnerable infants and their families

Area of Science:

• Child Psychology
• Developmental Psychology
• Clinical Science

Background:

• Early adversity significantly impacts child development.
• Existing interventions require adaptation for diverse populations facing adversity.
• Attachment theory and stress neurobiology provide a theoretical framework for intervention development.

Purpose of the Study:

• To describe the development of an evidence-based intervention for parents of young children with early adversity.
• To highlight key issues and challenges in adapting interventions for various at-risk populations.
• To offer advice for addressing similar challenges in intervention science.

Main Methods:

• Iterative adaptation of an intervention initially for foster infants.
• Application to infants with neglecting parents, internationally adopted children, and toddlers in foster care or with neglecting birth parents.
• Theoretical grounding in attachment theory and stress neurobiology, combined with clinical observation.

Main Results:

• Successful adaptation of a core intervention across multiple high-risk child populations.
• Demonstrated importance of providing nurturance during child distress and respecting child-led interactions.
• Identification of key challenges in intervention development and adaptation.

Conclusions:

• An evidence-based intervention can be effectively adapted for parents of young children with diverse early adversities.
• Attachment and stress neurobiology are crucial theoretical underpinnings for such interventions.
• Clinical scientists must remain open to hypothesis testing and data-driven refinement.
