Early externalizing behavior problems: Toddlers and preschoolers at risk for later maladjustment

The early emergence and developmental implications of externalizing behavior problems in toddlers and preschoolers are discussed with an emphasis on which young children are truly at risk for continuing problems. The extant literature is reviewed with a focus on the stability of early externalizing behavior and the diverse pathways that young children, primarily boys, with early-emerging problems may follow. Findings from a number of studies, both epidemiological and high risk, suggest that the small subgroup of boys with multiple risk factors that include especially high levels of early hyperactivity and aggression, and high levels of negative parenting and family stress, are most likely to evidence continuing problems at school entry. Sociodemographic and neighborhood influences are also discussed, as are implications for future research and policy.

Anger regulation in disadvantaged preschool boys: strategies, antecedents, and the development of self-control.

Emotion regulation strategies observed during an age 3 1/2 frustration task were examined in relation to (a) angry affect during the frustration task, (b) child and maternal characteristics at age 1 1/2, and (c) indices of self-control at age 6 in a sample of low-income boys (Ns varied between 189 and 310, depending on the assessment). Shifting attention away from sources of frustration and seeking information about situational constraints were associated with decreased anger. Secure attachment and positive maternal control correlated positively with effective regulatory strategy use. Individual differences in strategy use predicted self-control at school entry, but in specific rather than general ways: Reliance on attention-shifting strategies corresponded with low externalizing problems and high cooperation; reliance on information gathering corresponded with high assertiveness.

Codevelopment of externalizing and internalizing problems in early childhood.

Using cross-domain latent growth modeling, we examined trajectories of externalizing and internalizing problems in disadvantaged boys followed from ages 2 to 6 years (N = 303). On average, externalizing problems gradually decreased and internalizing problems gradually increased. However, we found significant variability in individual-level trajectories. Higher levels of externalizing problems were associated with higher levels of internalizing problems; rates of change were also positively correlated across domains. In addition, high levels of externalizing problems predicted rapid increases in internalizing problems. In follow-up analyses involving child and parenting factors, the combination of high negative emotionality, low fearfulness, and high negative maternal control preceded high, nondecreasing externalizing trajectories. The combination of high negative emotionality, high fearfulness, and high negative maternal control preceded high, increasing internalizing trajectories. Taken together, the results indicate both general and specific processes in the development of early externalizing and internalizing problems.

Developmental theories of parental contributors to antisocial behavior.

In view of the increased interest in a developmental approach to psychopathology, and mounting evidence of the importance of parent-child interactions in the etiology of early antisocial behavior, the following questions were posed for this review. What theories of parent-child relationships and family management techniques are available? How developmental are they, how specific and transactional are they relative to parent and child behaviors involved? And how well do they cover the period in which antisocial behavior develops? Six theories have some developmental features but the attachment theories (by L. A. Sroufe, B. Egeland, and M. T. Greenberg) and two social learning theories (by G. R. Patterson and J. Martin) are most clearly developmental. They postulate reciprocal interactions of parent and child, and transformations in the form of normative changes in the child or changes in family processes. The social learning theories of Patterson and Martin are most specific, microanalytic in fact, as to the interaction processes involved, and the attachment theories at least specify kinds of behavior involved and also do not rely on traits or types of influence as their units of analysis. Conceptualization is most weak and overly general between late infancy and the preschool years. This gap makes it difficult to link attachment and social learning theories, both of which have driven a large number of studies. A bridging theory is offered to link the two sets of theories in the critical period involved.

Developmental Precursors of Externalizing Behavior: Ages 1 to 3

Despite previous research indicating that early negative child behavior and the quality of the parentchild relationship are predictive of later externalizing problems, few investigators have attempted to trace these antecedents back to infancy. In a sample of 100 infants from low-income families, it was possible to identify developmental sequences leading from infant persistence and lack of maternal responsiveness to later child disruptive, aggressive child behavior at ages 2 and 3. Gender differences were found with respect to the range and type of variables that showed continuity in predicting disruptive behavior. For boys, salient predictors of age 2 and age 3 externalizing behavior were maternal unresponsiveness, infant attention-seeking, aggression, and noncompliance, whereas for girls, infant noncompliance was related to both age 3 externalizing and internalizing problems.

Randomized trial of a family-centered approach to the prevention of early conduct problems: 2-Year effects of the family check-up in early childhood

Despite recent research indicating that 1 of the pivotal times for identifying pathways to early conduct problems is the toddler period, few family-based preventive interventions have been specifically designed to modify child disruptive behavior during this age period. This randomized trial tested the effectiveness of the Family Check-Up in sustaining maternal involvement and preventing the exacerbation of child conduct problems among 120 at-risk toddler-age boys, half of whom were randomly assigned to a treatment condition. The intervention was associated with reductions in disruptive behavior and greater maternal involvement and was particularly effective for children at greater risk for a persistent trajectory of conduct problems. The results are discussed in relation to other preventive interventions for young children.

The Development of Early Externalizing Problems Among Children from Low-Income Families: A Transformational Perspective

The present study examined pathways leading to early externalizing problems from age 1 to 31/2 in a design that took advantage of our knowledge of normative progression and normative socialization as well as findings from research on risk. A sample of 130 low-income participants was followed longitudinally from 12 to 42 months using observational measures of developmentally salient parenting and child disruptive behavior to predict early externalizing problems. Results are best accommodated by concepts such as transformation and transaction from developmental psychology. For boys, both child and parent variables predicted later externalizing. For girls and boys, the interaction between child noncompliance and maternal rejection was significant.

Evidence for the continuity of early problem behaviors: Application of a developmental model.

Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented.

Early risk factors and pathways in the development of early disruptive behavior problems

This study examined risk factors from infancy associated with the development of preschool disruptive behavior problems across child, parent, and sociodemographic domains. Risk factors that consistently were associated with the prediction of disruptive behavior at age 5 years included disorganized attachment classification at 12 months, and maternal personality risk and child-rearing disagreements during the second year. In addition, infants with disorganized attachment status at 12 months whose mothers perceived them as difficult in the second year showed significantly higher aggressive problems at age 5 years than those with only one of the two risk factors present. When pathways leading to clinically elevated aggression at age 5 were explored, infant disorganized attachment status, maternal personality risk, and child-rearing disagreements demonstrated equivalent predictive validity as child aggression assessed at age 3 years.

Neighborhood Contextual Factors and Early-Starting Antisocial Pathways

This paper examines research investigating the effects of neighborhood context on the onset and persistence of early-starting antisocial pathways across middle and late childhood. The review begins by presenting theory and research mapping the early-starting developmental pathway. Next, sociologically and psychologically based investigations linking neighborhood context and early antisocial behavior are examined, in order to posit and evaluate the effects of community economic disadvantage, exposure to neighborhood violence, and involvement with neighborhood-based deviant peer groups on the development of antisocial behavior. It is suggested that middle childhood may represent a critical developmental period during which children are at heightened risk for neighborhood-based effects on antisocial behavior problems. Key methodological issues are addressed, and recommendations for future research integrating developmental pathways and neighborhood theory and research are advanced.
