A developmental perspective on antisocial behavior.

A developmental model of antisocial behavior is outlined. Recent findings are reviewed that concern the etiology and course of antisocial behavior from early childhood through adolescence. Evidence is presented in support of the hypothesis that the route to chronic delinquency is marked by a reliable developmental sequence of experiences. As a first step, ineffective parenting practices are viewed as determinants for childhood conduct disorders. The general model also takes into account the contextual variables that influence the family interaction process. As a second step, the conduct-disordered behaviors lead to academic failure and peer rejection. These dual failures lead, in turn, to increased risk for depressed mood and involvement in a deviant peer group. This third step usually occurs during later childhood and early adolescence. It is assumed that children following this developmental sequence are at high risk for engaging in chronic delinquent behavior. Finally, implications for prevention and intervention are discussed.

The Correlation of Family Management Practices and Delinquency.

Family-management skills of parents of seventh- and tenth-grade boys were related to each of 2 criterion measures of delinquency: police contacts and self-reported delinquency. The measures of family-management skills were monitoring, discipline, problem solving, and reinforcement. The measures of parent monitoring and discipline were shown to correlate significantly with both criterion measures. The monitoring score accounted for the most variance in both criterion measures of delinquency, and the problem solving and reinforcement measures accounted for the least. The monitoring score also differentiated moderate offenders from persistent offenders.

Toward a comprehensive model of antisocial development : A dynamic systems approach

The purpose of this article is to develop a preliminary comprehensive model of antisocial development based on dynamic systems principles. The model is built on the foundations of behavioral research on coercion theory. First, the authors focus on the principles of multistability, feedback, and nonlinear causality to reconceptualize real-time parent-child and peer processes. Second, they model the mechanisms by which these real-time processes give rise to negative developmental outcomes, which in turn feed back to determine real-time interactions. Third, they examine mechanisms of change and stability in early- and late-onset antisocial trajectories. Finally, novel clinical designs and predictions are introduced. The authors highlight new predictions and present studies that have tested aspects of the model

A comparative evaluation of a parent-training program*

This report is one of a series of outcome evaluation studies for parent-training procedures tailored specifically to families of preadolescent antisocial children. Referred families were screened to identify 19 problem children who were observed in their homes to be high-rate social aggressors. Cases were randomly assigned to the parent-training procedures or to a waiting-list comparison group. All but one of the latter accepted a referral for treatment elsewhere in the community. After an average of 17 hours of therapy time, the cases in the experimental group were terminated. Posttreatment observation data were collected in the homes of both the experimental and the comparison groups. The results indicated that, relative to the changes in the comparison sample, the parenttraining sample showed a significantly greater reduction in the observed rates of deviant child behavior.

Variables that initiate and maintain an early-onset trajectory for juvenile offending.

A trajectory defined by three time-ordered events was offered as a useful adjunct to building a development theory about antisocial behaviors. A sequence was defined with significant linkages between antisocial childhood behavior and early arrest and between early arrest and chronic offending. The majority of chronic offenders traveled through all three events in the sequence. Each event in the sequence shared a common process of disrupted family process plus frequent family transitions and marked social disadvantage. The findings support the hypothesis that the process that leads to antisocial behaviors at grade four may also maintain the entire sequence. The level of disrupted process at initiation and a time-based measure of involvement with deviant peers predicted which individuals moved forward in the sequence and which did not. The findings are consistent with the idea that the majority of chronic offending juveniles follow a trajectory that can be explained by a single theory.

Adolescent Growth in New Forms of Problem Behavior: Macro- and Micro-Peer Dynamics

Longitudinal data from an at-risk sample were used to analyze individual linear trend scores for each of three new forms of problem behavior that emerges during the interval from age 10 through 18 years. Growth in substance use, health-risking sexual behavior and police arrests defined a latent construct for growth in adolescent problem behavior. A structural equation model (SEM) showed a significant path from early involvement with deviant peers to a latent construct for growth in new forms of antisocial behavior. A second SEM showed that the contribution of early involvement to later growth was mediated by a latent construct for deviancy training assessed at age 14 years. The relative rates of reinforcement for deviancy, amount of time spent with deviant peers, and deviancy level of the peer network defined a deviancy training construct that accounted for 53% of the variance in later growth in new forms.

Family interaction: A process model of deviancy training

A model was presented describing the reciprocal influence of disruptions in parent discipline practices on irritable exchanges between the target child and other family members. Disrupted parent discipline and irritable microsocial exchanges within the family were hypothesized to provide a basic training for aggression that generalizes to other settings such that the child is identified by peers, teachers, and parents as physically aggressive. Physical fighting was thought to lead to rejection by the normal peer group, which was hypothesized to feed back to further exacerbate fighting. Multilevel assessment including interview, questionnaires, laboratory studies, and home observations were carried out with the families of 91 preadolescent and adolescent boys. Nine indicators from the assessment battery were used to define the constructs Inept Parental Discipline, Negative Microsocial Exchanges, Physical Fighting, and Poor Peer Relations. Structural equations (LISREL VI) were used to describe the relations among the constructs. The t values for the path coefficients were significant. A chi-square analysis showed an acceptable fit between the model and the empirical findings. The findings were interpreted as being consistent with the hypothesis that under certain circumstances, family interaction may serve as basic training for aggression. In the present study, interactions with siblings in the home seemed to serve a pivotal role.

Orderly Change in a Stable World: The Antisocial Trait as a Chimera.

Childrens traits, such as antisocial behavior, are embedded in a matrix that is changing over time. Although the trait score is stable, there are changes in the form of antisocial acts. There can also be subgroups of boys who show systematic increases in mean level of antisocial behavior. Latent growth models were used to demonstrate both changes in form and systematic changes in mean level for a subgroup of boys. The analyses included measures of covariates that were thought necessary to cause these changes. There are also qualitative changes brought about by the presence of the antisocial trait itself (e.g., academic failure, peer rejection, and depressed mood). Factor analyses carried out at three ages showed that, over time, both the changes in form and the addition of new problems are quantifiable and thus represent orderly change.

How Do Outcomes in a Specified Parent Training Intervention Maintain or Wane Over Time

In a randomized prevention trial, 238 recently separated mothers and their young sons were assigned to either Parent Management Training (PMT) or a comparison group. Families were intensively assessed at baseline and at each 6-month interval through 30 months. To understand the effects of PMT, we first evaluated effect sizes among family variables over time. Second, because observed parenting was the target of PMT, we hypothesized a sequential pattern of structured changes within and between individuals. Using constructs with mismatched sources of data, we conducted a set of latent growth mediational analyses to test hypothesized mechanisms explaining change. Effect sizes indicated that parenting changed first within 12 months, followed by changes in boy behaviors and finally changes in maternal depression within 30 months. Unique follow-up findings indicated that intervention effects on reductions in maternal depression were mediated by reductions in boy externalizing; intervention effects on externalizing were mediated by reductions in boy depression. As expected, increases in effective parenting predicted reductions in child behavior problems. PMT effects on internalizing were direct and indirect, partially mediated by parenting practices. Results are discussed from a systems perspective on PMT amplifiers.
