Insights
Children with low cortisol and disorganized attachment showed more problem behaviors. Secure attachment buffered this effect, suggesting complex socioemotional development in poverty.
Area of Science:
- Developmental Psychology
- Child Psychiatry
- Socioemotional Development
Background:
- Childhood problem behaviors are influenced by biological and environmental factors.
- Attachment classification reflects early caregiving quality and impacts development.
- Poverty presents unique challenges to socioemotional development.
Purpose of the Study:
- To predict problem behaviors in young children using baseline cortisol and attachment classification.
- To investigate the interaction between cortisol levels and attachment in predicting behavioral outcomes.
- To explore implications for socioemotional development in children experiencing poverty.
Main Methods:
- Assessed baseline cortisol levels, attachment classification, and problem behaviors in 58 children at 17 months.
- Utilized a sample of children living at or below the federal poverty threshold.
- Examined interaction effects between cortisol and attachment on problem behaviors.
Main Results:
- No significant differences in problem behaviors were found for children with high baseline cortisol.
- Children with low baseline cortisol exhibited higher problem behaviors when displaying disorganized attachment.
- Low baseline cortisol did not predict increased problem behaviors in children with secure attachment.
Conclusions:
- Attachment security plays a crucial role in moderating the relationship between cortisol and problem behaviors.
- Findings align with diathesis-stress models, highlighting vulnerability in certain child-environment contexts.
- Early interventions focusing on attachment and stress regulation may support socioemotional development in at-risk children.
Abstract:
The purpose of the current study was to predict concurrent levels of problem behaviors from young children's baseline cortisol and attachment classification, a proxy for the quality of caregiving experienced. In a sample of 58 children living at or below the federal poverty threshold, children's baseline cortisol levels, attachment classification, and problem behaviors were assessed at 17 months of age. We hypothesized that an interaction between baseline cortisol and attachment classification would predict problem behaviors above and beyond any main effects of baseline cortisol and attachment. However, based on limited prior research, we did not predict whether or not this interaction would be more consistent with diathesis-stress or differential susceptibility models. Consistent with diathesis-stress theory, the results indicated no significant differences in problem behavior levels among children with high baseline cortisol. In contrast, children with low baseline cortisol had the highest level of problem behaviors in the context of a disorganized attachment relationship. However, in the context of a secure attachment relationship, children with low baseline cortisol looked no different, with respect to problem behavior levels, then children with high cortisol levels. These findings have substantive implications for the socioemotional development of children reared in poverty.
