3. Background Attachment
Stability and instability
Low-risk versus high-risk
Predictors of attachment stability
Domestic violence
Income
Maternal caregiving representations
Gender
4. Hypotheses/Research Questions What is the concordance rate of attachment in this heterogeneous for risk group from ages 1 to 4?
How does the trajectory of DV influence the change/stability of the child’s attachment classifications from ages 1 to 4?
How does the trajectory of Income influence the change/stability of the child’s attachment classifications from ages 1 to 4?
5. Hypotheses/Research Questions How does the change/stability of Maternal Representations from prenatal to 1 year postnatal affect the change/stability of attachment from ages 1 to 4?
How is Gender related to attachment change/stability from ages 1 to 4?
6. Longitudinal Study Research design

47% single, 43% married
42% high school or less, 44% trade school or some college
Children
72 males, 78 females
47% Caucasian, 25% African-American, 24% Multiracial
8. Measures Demographics

10. Attachment Classifications
11. Patterns of Attachment Secure-Secure n = 58
Secure-Insecure n = 26
Insecure-Secure n = 38
Insecure-Insecure n = 28
12. Results – Domestic Violence Trajectory Repeated Measures ANOVA
5 periods of DV (prenatal, age 1, age 2, age 3 and age 4)
Significant time by pattern interaction
Linear effect of time – all groups decreased in DV over time
Quadratic effect of time by pattern – such that there were different curvature for the trajectories
Secure-insecure group had relatively low rates of DV with a concave trajectory
Insecure-insecure group had highest rates of prenatal DV with a convex trajectory
13. Results – Income Trajectory Repeated Measures ANOVA
5 time periods (prenatal, age 1, age 2, age 3, and age 4)
Significant effect of time by pattern
Cubic effect of time by pattern
Secure-secure group had significantly higher income over all times compared with both insecure-secure and insecure-insecure groups
Insecure-secure group began with relatively low income which steadily and slowly rose over time
14. Results – Maternal Representations Using chi-sq and Configural Frequency Analysis
Significant relationship between pattern of maternal representations and patterns of attachment
Types:
secure-secure and balanced-balanced
unstable attachment and unstable maternal representations
unstable attachment and nonbalanced-nonbalanced
Insecure-insecure and balanced-nonbalanced
15. Results - Gender Significant difference in attachment classifications by gender
More girls secure at age 1 and more boys secure at age 4
No interaction with DV
Interaction with Maternal Representations
Stability and instability of maternal representations predicted stability or instability of attachment for boys but not for girls
16. Discussion Attachment concordance not significant
Predictors:
Domestic violence disrupts mother-child relationship and/or is associated with emotional dysregulation in the child
Low income (i.e. economic distress) disrupts parenting behavior and affects mother-child relationship
17. Discussion Predictors (continued)
Stability of maternal balanced representations was a protective factor for stability of secure attachment
Gender was associated with change in maternal representations and subsequently in attachment classifications
Experiences with male infant positively influenced maternal representations
18. Limitations and Conclusions All maternal report
Domestic violence trajectory
Support for broader theory about influence of environmental factors on stability and instability of attachment
