Executive functioning, temporal discounting, and sense of time in adolescents with attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD).

Clinic-referred teens (ages 12-19) with ADHD and ODD (N = 101) were compared to community control (CC) teens, equated for age and sex, (N = 39) on a variety of psychological tasks assessing executive functioning (EF), temporal reward discounting, and time estimation and reproduction. A factor analysis reduced the EF measures to three dimensions, representing CPF Inattention, Working Memory, and CPT Inhibition. Results indicated that the ADHD group had significantly more CPT Inattention than the CC group. No differences were found for Working Memory or CPT Inhibition. The ADHD group displayed significantly greater temporal discounting of delayed hypothetical monetary rewards relative to immediate ones and manifested more impaired time reproduction, but not time estimation, than did the CC group. Main effects for level of IQ were found only on the Working Memory factor and largely did not interact with the group factor otherwise. The group differences in CPT Inattention, temporal discounting, and time reproduction were not a function of level of comorbid oppositional defiant disorder, delinquency, or anxiety-depression. Results are reasonably consistent with past research on EF and sense of time in children with ADHD and extend these findings to the adolescent age group. Problems with working memory and CPT inhibition found in prior studies of children with ADHD, however, were not evident here, perhaps owing to age-related improvements or insufficient task difficulty.

Parent-adolescent conflict in teenagers with ADHD and ODD.

Eighty-seven male teens (ages 12-18 years) with ADHD/ODD and their parents were compared to 32 male teens and their parents in a community control (CC) group on mother, father, and teen ratings of parent-teen conflict and communication quality, parental self-reports of psychological adjustment, and direct observations of parent-teen problem-solving interactions during a neutral and conflict discussion. Parents and teens in the ADHD/ODD group rated themselves as having significantly more issues involving parent-teen conflict, more anger during these conflict discussions, and more negative communication generally, and used more aggressive conflict tactics with each other than did parents and teens in the CC group. During a neutral discussion, only the ADHD/ODD teens demonstrated more negative behavior. During the conflict discussion, however, the mothers, fathers, and teens in the ADHD/ODD group displayed more negative behavior, and the mothers and teens showed less positive behavior than did participants in the CC group. Differences in conflicts related to sex of parent were evident on only a few measures. Both mother and father self-rated hostility contributed to the level of mother-teen conflict whereas father self-rated hostility and anxiety contributed to father-teen conflict beyond the contribution made by level of teen ODD and ADHD symptoms. Results replicated past studies of mother-child interactions in ADHD/ODD children, extended these results to teens with these disorders, showed that greater conflict also occurs in father-teen interactions, and found that degree of parental hostility, but not ADHD symptoms, further contributed to levels of parent-teen conflict beyond the contribution made by severity of teen ADHD and ODD symptoms.

The efficacy of problem-solving communication training alone, behavior management training alone, and their combination for parent-adolescent conflict in teenagers with ADHD and ODD.

Two family therapies were compared using teens with attention-deficit/hyperactivity disorder. Ninety-seven families were assigned to either 18 sessions of problem-solving communication training (PSCT) alone or behavior management training (BMT) for 9 sessions followed by PSCT for 9 sessions (BMT/PSCT). Both treatments demonstrated significant improvement in ratings of parent-teen conflicts at the midpoint but did not differ. By posttreatment, both produced improvement on ratings and observations but did not differ. Significantly more families dropped out of PSCT alone than out of BMT/PSCT. At most, 23% of families showed reliable change either by midpoint or by posttreatment, with no differences between therapies. Yet 31%-70% of families were normalized. Group-level change and normalization rates support treatment efficacy, whereas indices of reliable change are less impressive.

Multimethod psychoeducational intervention for preschool children with disruptive behavior: two-year post-treatment follow-up.

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.

Multi-method psycho-educational intervention for preschool children with disruptive behavior: preliminary results at post-treatment.

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.

Psychiatric and psychological morbidity as a function of adaptive disability in preschool children with aggressive and hyperactive-impulsive-inattentive behavior.

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.
