Maternal and Paternal Sensitivity: Key Determinants of Child Attachment Security Examined Through Meta-Analysis.

Sensitive caregiving behavior, which involves the ability to notice, interpret, and quickly respond to a child's signals of need and/or interest, is a central determinant of secure child–caregiver attachment. Yet, significant heterogeneity in effect sizes exists across the literature, and sources of heterogeneity have yet to be explained. For all child–caregiver dyads, there was a significant and positive pooled association between caregiver sensitivity and parent–child attachment (r =.25, 95% CI [.22,.28], k = 174, 230 effect sizes, N = 22,914). We also found a positive association between maternal sensitivity and child attachment security (r =.26, 95% CI [.22,.29], k = 159, 202 effect sizes, N = 21,483), which was equivalent in magnitude to paternal sensitivity and child attachment security (r =.21, 95% CI [.14, 27], k = 22, 23 effect sizes, N = 1,626). Maternal sensitivity was also negatively associated with all three classifications of insecure attachment (avoidant: k = 43, r = −.24 [−.34, −.13]; resistant: k = 43, r = −.12 [−.19, −.06]; disorganized: k = 24, r = −.19 [−.27, −.11]). For maternal sensitivity, associations were larger in studies that used the Attachment Q-Sort (vs. the Strange Situation), used the Maternal Behavior Q-Sort (vs. Ainsworth or Emotional Availability Scales), had strong (vs. poor) interrater measurement reliability, had a longer observation of sensitivity, and had less time elapse between assessments. For paternal sensitivity, associations were larger in older (vs. younger) fathers and children. These findings confirm the importance of both maternal and paternal sensitivity for the development of child attachment security and add understanding of the methodological and substantive factors that allow this effect to be observed. Public Significance Statement: The quality of care children receive from caregivers can shape the foundations of a thriving society. Sensitive caregiver behavior involves the ability to notice, interpret, and quickly respond to a child's signals of need and/or interest. Findings from our research suggests that caregivers' sensitive behavior toward their child plays a pivotal role in fostering children's secure attachment. We found that associations were similar for both mothers and fathers. These findings stress the urgency of allocating resources and supports to enhance sensitive caregiver behavior, to in turn promote healthier child–parent relationships. [ABSTRACT FROM AUTHOR]
