Secure Base Provision: A New Approach to Examining Links Between Maternal Caregiving and Infant Attachment

Area of Science:

• Developmental Psychology
• Attachment Theory
• Maternal Caregiving

Background:

• Understanding infant attachment precursors is crucial for early development.
• Maternal caregiving behaviors significantly influence infant attachment security.
• Existing research often focuses on maternal sensitivity, but other factors may be important.

Purpose of the Study:

• To examine secure base provision (SBP) as a predictor of infant attachment.
• To determine if SBP explains attachment variance beyond maternal sensitivity.
• To investigate these relationships in low-socioeconomic status (SES) families.

Main Methods:

• Observational study design.
• 83 low-SES infants and their mothers participated.
• Data collected via laboratory tasks and home visits at 4.5, 7-9, and 12 months.

Main Results:

• Maternal sensitivity did not significantly predict infant attachment security.
• Secure base provision (SBP) significantly predicted infant attachment.
• SBP's effect size was eight times larger than sensitivity's in meta-analytic findings for low-SES families.

Conclusions:

• Secure base provision is a critical factor in infant attachment, particularly for low-SES populations.
• SBP offers a more robust explanation for infant attachment than maternal sensitivity alone.
• Findings highlight the importance of considering SBP in interventions aimed at promoting secure infant attachment.
