Families of 97 children with early-onset conduct problems, 4 to 8 years old, were randomly assigned to 1 of 4 conditions: a parent training treatment group (PT), a child training group (CT), a combined child and parent training group (CT + PT), or a waiting-list control group (CON). Posttreatment assessments indicated that all 3 treatment conditions had resulted in significant improvements in comparison with controls. Comparisons of the 3 treatment conditions indicated that CT and CT + PT children showed significant improvements in problem solving as well as conflict management skills, as measured by observations of their interactions with a best friend; differences among treatment conditions on these measures consistently favored the CT condition over the PT condition. As for parent and child behavior at home, PT and CT + PT parents and children had significantly more positive interactions, compared with CT parents and children. One-year follow-up assessments indicated that all the significant changes noted immediately posttreatment had been maintained over time. Moreover, child conduct problems at home had significantly lessened over time. Analyses of the clinical significance of the results suggested that the combined CT + PT condition produced the most significant improvements in child behavior at 1-year follow-up.

The effectiveness of a parenting program with 394 Head Start mothers was examined. Nine Head Start centers were randomly assigned to either an experimental condition in which parents, teachers, and family service workers participated in the intervention or a control condition in which the regular Head Start program was offered. Mothers in the intervention group were observed at home to have significantly fewer critical remarks and commands, to use less harsh discipline, and to be more positive and competent in their parenting when compared with control mothers. Teachers reported that intervention mothers were more involved in their children's education and that their children were more socially competent. Intervention children were observed to exhibit significantly fewer conduct problems, less noncompliance, less negative affect, and more positive affect than control children. One year later most of the improvements were maintained.

Studied the effectiveness of parent and teacher training as a selective prevention program for 272 Head Start mothers and their 4-year-old children and 61 Head Start teachers. Fourteen Head Start centers (34 classrooms) were randomly assigned to (a) an experimental condition in which parents, teachers, and family service workers participated in the prevention program (Incredible Years) or (b) a control condition consisting of the regular Head Start program. Assessments included teacher and parent reports of child behavior and independent observations at home and at school. Construct scores combining observational and report data were calculated for negative and positive parenting style, parent-teacher bonding, child conduct problems at home and at school, and teacher classroom management style. Following the 12-session weekly program, experimental mothers had significantly lower negative parenting and significantly higher positive parenting scores than control mothers. Parent-teacher bonding was significantly higher for experimental than for control mothers. Experimental children showed significantly fewer conduct problems at school than control children. Children of mothers who attended 6 or more intervention sessions showed significantly fewer conduct problems at home than control children. Children who were the "highest risk" at baseline (high rates of noncompliant and aggressive behavior) showed more clinically significant reductions in these behaviors than high-risk control children. After training, experimental teachers showed significantly better classroom management skills than control teachers. One year later the experimental effects were maintained for parents who attended more than 6 groups. The clinically significant reductions in behavior problems for the highest risk experimental children were also maintained. Implications of this prevention program as a strategy for reducing risk factors leading to delinquency by promoting social competence, school readiness, and reducing conduct problems are discussed.

Families of 159, 4- to 8-year-old children with oppositional defiant disorder (ODD) were randomly assigned to parent training (PT); parent plus teacher training (PT + TT); child training (CT); child plus teacher training (CT + TT); parent, child, plus teacher training (PT + CT + TT); or a waiting list control. Reports and independent observations were collected at home and school. Following the 6-month intervention, all treatments resulted in significantly fewer conduct problems with mothers, teachers, and peers compared to controls. Children's negative behavior with fathers was lower in the 3 PT conditions than in control. Children showed more prosocial skills with peers in the CT conditions than in control. All PT conditions resulted in less negative and more positive parenting for mothers and less negative parenting for fathers than in control. Mothers and teachers were also less negative than controls when children received CT. Adding TT to PT or CT improved treatment outcome in terms of teacher behavior management in the classroom and in reports of behavior problems.

Background-School readiness, conceptualized as three components including emotional selfregulation, social competence, and family/school involvement, as well as absence of conduct problems play a key role in young children's future interpersonal adjustment and academic success. Unfortunately, exposure to multiple poverty-related risks increases the odds that children will demonstrate increased emotional dysregulation, fewer social skills, less teacher/parent involvement and more conduct problems. Consequently intervention offered to socio-economically disadvantaged populations that includes a social and emotional school curriculum and trains teachers in effective classroom management skills and in promotion of parent-school involvement would seem to be a strategic strategy for improving young children's school readiness, leading to later academic success and prevention of the development of conduct disorders.

Several child conduct problem interventions have been classified as either efficacious or well established. Nevertheless, much remains to be learned about predictors of treatment response and mechanisms of behavioral change. In this study, the authors combine data from 6 randomized clinical trials and 514 children, ages 3.0-8.5 years, to evaluate moderators, mediators, and predictors of outcome. Among other findings, latent growth curve models of mother-report and observational measures of child externalizing behaviors suggested that marital adjustment, maternal depression, paternal substance abuse, and child comorbid anxiety/depression each moderated treatment response. Moreover, critical, harsh, and ineffective parenting both predicted and mediated outcome, with the most favorable responses observed when parents scored relatively low on each construct at intake yet improved during treatment. Implications for treatment nonresponders are discussed.
