This paper describes the 2-year post-treatment follow-up of preschool children identified as having high levels of disruptive behavior at kindergarten entry. They were assigned to four treatment conditions: A no-treatment group, parent-training only, treatment classroom only, and the combination of parent training with the treatment classroom. Interventions lasted the entire kindergarten academic year. Initial post-treatment results reported previously indicated no effects for the parent-training program but some efficacy for the classroom intervention program. For this report, the disruptive behavior (DB) children were subdivided into those who did (n = 74) and did not (n = 77) receive the treatment classroom. Two-year post-treatment follow-up results indicated no differences between the classroom treated and untreated DB groups. These groups also failed to differ in the percentage of children using available treatments across the follow-up period. The DB children in both groups had significantly more symptoms of ADHD and ODD than a community control group (N = 47) at follow-up. They also received higher ratings of externalizing problems on the parent Child Behavior Checklist, more severe ratings of behavior problems at home, and ratings of more pervasive behavior problems at school, and had poorer academic skills. Results suggested that early intervention classrooms for DB children may not produce enduring effects once treatment is withdrawn, and that better approaches are needed for identifying those DB children at greatest risk for later maladjustment.

Children with high levels of aggressive-hyperactive-impulsive-inattentive behavior (AHII; n = 154) were subdivided into those with (n = 38) and without (n = 116) adaptive disability (+AD/-AD) defined as a discrepancy between expected versus actual adaptive functioning. They were compared to each other and a control group of 47 normal children. Both AHII groups were more likely to have attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder, and conduct disorder than control children; more symptoms of general psychopathology; greater social skills deficits; more parental problems; and lower levels of academic achievement skills. Compared to AHII - AD children, AHII + AD children had (1) more conduct disorder; (2) greater inattention and aggression symptoms; (3) more social problems, less academic competence, and poorer self-control at school; (4) more severe and pervasive behavior problems across multiple home and school settings; and (5) parents with poorer child management practices. Thus, adaptive disability has utility as a marker for more severe and pervasive impairments in AHII children. [ABSTRACT FROM AUTHOR]

A significant discrepancy between intelligence and daily adaptive functioning, or adaptive disability (AD), has been previously found to be a associated with significant psychological morbidity in preschool children with disruptive behavior (DB). The utility of AD as a predictor of later developmental risks was examined in a 3-year longitudinal study of normal (N = 43) and DB preschool children. The DB children were grouped into those with AD (DB+AD; N = 28) and those without AD (DB-only; N = 98). All children were followed with annual evaluations to the end of second grade. Both DB groups demonstrated substantial and pervasive psychological and educational morbidity at 3-year follow-up. In comparison to DB-only children, DB+AD children had more symptoms of attention-deficit hyperactivity disorder (ADHD) and conduct disorder (CD), more severe and pervasive behavior problems at home, more parent-rated externalizing and internalizing, and lower academic competence and more behavioral problems at school. Parents of DB+AD children also reported greater parenting stress than did parents in the other groups. A significant contribution of AD to adverse outcomes in the DB group remained on some measures even after controlling for initial severity of DB. AD also contributed significantly to CD symptoms at follow-up after controlling for initial DB severity and initial CD symptoms. The results corroborate and extend earlier findings of the utility of AD as a risk indicator above severity of DB alone. They also imply that AD in the context of normal intellectual development may arise from both the deficient self-regulation associated with ADHD and from disrupted parenting. with exposure to kindergarten moderating these adverse effects.

Annual screenings of preschool children at kindergarten registration identified 158 children having high levels of aggressive, hyperactive, impulsive, and inattentive behavior. These "disruptive" children were randomly assigned to four treatment conditions lasting the kindergarten school year: no treatment, parent training only, full-day treatment classroom only, and the combination of parent training with the classroom treatment. Results showed that parent training produced no significant treatment effects, probably owing largely to poor attendance. The classroom treatment produced improvement in multiple domains: parent ratings of adaptive behavior, teacher ratings of attention, aggression, self-control, and social skills, as well as direct observations of externalizing behavior in the classroom. Neither treatment improved academic achievement skills or parent ratings of home behavior problems, nor were effects evident on any lab measures of attention, impulse control, or mother-child interactions. It is concluded that when parent training is offered at school registration to parents of disruptive children identified through a brief school registration screening, it may not be a useful approach to treating the home and community behavioral problems of such children. The kindergarten classroom intervention was far more effective in reducing the perceived behavioral problems and impaired social skills of these children. Even so, most treatment effects were specific to the school environment and did not affect achievement skills. These findings must be viewed as tentative until follow-up evaluations can be done to determine the long-term outcomes of these interventions.
