Infant attachment strategies, infant mental lag, and maternal depressive symptoms: predictors of internalizing and externalizing problems at age 7

The predictive relations between assessments in infancy and parent- and teacher-reported behavior problems at age 7 were investigated within a low-income sample. Infancy assessments indexed family adversity, parent-infant interaction at home, infant attachment, infant anger-distress at home, gender, and cognitive functioning. Among children at age 7 identified by teachers as highly externalizing, 83% were both disorganized in their attachment behavior in infancy and below the national mean in mental development scores at 18 months, compared with 13% of nonexternalizing children. Avoidant attachment behavior in infancy was associated with later internalizing symptoms rather than with externalizing symptoms. The behavior problem data reported by mother suggested the possibility of attachment-related biases in maternal report data. The results indicate that child mental lag in the context of a disorganized attachment relationship constitutes 1 early step on the pathway to school-age externalizing behavior.     

Attachment relationships among children with aggressive behavior problems: The role of disorganized early attachment patterns.

Reviews attachment-related studies of early aggression to show that aggressive behavior toward peers is related to disorganized or controlling patterns of attachment behavior toward parents but not to avoidant or ambivalent patterns. Longitudinal attachment studies indicate that risk factors identified in cross-sectional studies of aggressive school-age children, such as family adversity, parental hostility, parental depression, and child cognitive deficits, are already evident in infancy and predictive of later aggression, before the onset of coercive child behavior. In infancy, these risk factors are associated with disorganized attachment behaviors toward the caregiver characterized by signs of fear or dysphoria, irresolvable conflict between opposing behavioral tendencies, and elevated cortisol levels after separation. Disorganized attachment behaviors, in turn, predict aggression in school-age children with other family factors controlled. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Infants at social risk: Relations among infant maltreatment, maternal behavior, and infant attachment behavior.

Fifty-six 12-mo-old infants, including 10 maltreated infants, 18 nonmaltreated high-risk infants, and 28 matched low-income controls, were videotaped in naturalistic settings at home with their mothers for 40 min and were observed 2 weeks later in the Ainsworth Strange Situation. Maltreating mothers were rated higher than nonmaltreating mothers on covertly hostile and interfering behaviors toward their infants at home. Maltreated infants were more avoidant of their mothers in the Strange Situation than nonmaltreated infants. Correlations between maternal behaviors at home and infant behaviors in the Strange Situation revealed that mothers whose infants displayed resistant behavior on reunion were rated at home as less verbally communicative and mothers whose infants displayed avoidant behavior on reunion were rated at home as more covertly hostile. Infants showing mixed avoidance and resistance were more likely to have extremely uncommunicative mothers than were infants who showed avoidance alone. Use of the behavioral rating scales for avoidance and resistance produced clearer findings than use of the final attachment classifications. Reasons for the discrepancies between analyses of classifications and analyses of behavior ratings were identified. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Broadening our conceptual frameworks: Can we reintroduce relational strategies and implicit representational systems to the study of psychopathology?

In the context of current studies of parental depression, methodological and conceptual issues related to the study of relational behavior are highlighted in this commentary. These issues include the need to develop measures of relational behavior that are well-validated in high-risk samples, the need to develop relational assessments focused around central motivating systems, the need for methods that describe a variety of individual relational patterns rather than focusing primarily on single linear dimensions of behavior, and the need to consider the implicit and explicit meaning systems that guide behavior in close relationships. It is suggested that a relational systems perspective might provide a more comprehensive framework for understanding the results of accumulated research in this area than a simpler mood-disorder model.
