Insights
Early childhood attachment insecurity, particularly disorganized attachment, is linked to externalizing behavior problems. This risk is higher for boys in risky contexts, underscoring attachment
Area of Science:
- Child Psychology
- Developmental Psychology
- Attachment Theory
Background:
- Attachment insecurity is hypothesized to increase the risk for childhood externalizing behavior problems.
- Understanding the nuances of early attachment is crucial for identifying at-risk children.
Purpose of the Study:
- To investigate the association between early attachment styles and the development of externalizing behavior problems in children.
- To examine how factors like family risk, child gender, and age moderate this association.
Main Methods:
- Latent-growth curve modeling was employed.
- Data from 1,364 children in the NICHD Study of Early Child Care were analyzed.
- Teacher-rated externalizing problems were assessed across primary school years.
Main Results:
- Both avoidant and disorganized attachment predicted higher levels of externalizing problems.
- Disorganized attachment's impact was moderated by cumulative family risk, child gender, and age.
- Disorganized boys in high-risk social contexts showed increasing behavior problems over time.
Conclusions:
- Early attachment plays a conditional role in children's externalizing behavior.
- Further research is needed to explore causal pathways and mediating mechanisms.
- Intervention strategies may need to consider attachment security and contextual risks.
Background:
Some contend that attachment insecurity increases risk for the development of externalizing behavior problems in children.
Method:
Latent-growth curve analyses were applied to data on 1,364 children from the NICHD Study of Early Child Care to evaluate the association between early attachment and teacher-rated externalizing problems across the primary-school years.
Results:
Findings indicate that (a) both avoidant and disorganized attachment predict higher levels of externalizing problems but (b) that effects of disorganized attachment are moderated by family cumulative contextual risk, child gender and child age, with disorganized boys from risky social contexts manifesting increases in behavior problems over time.
Conclusions:
These findings highlight the potentially conditional role of early attachment in children's externalizing behavior problems and the need for further research evaluating causation and mediating mechanisms.
