The findings highlight the importance of assessing parents' use of alternate treatments for ADHD and the potential role of parents' beliefs and attributions in shaping treatment choices.

The authors examined changes over a 1-year period in mothers' attributions for child behavior and child oppositional behavior among 53 mothers and nonproblem sons and 44 mothers and sons with attention-deficit/hyperactivity disorder (ADHD). Boys averaged 8 years of age (SD = 11 months) at Time 1. Families were primarily of European Canadian cultural background and most were middle to upper middle class. Initial levels of child oppositionality did not predict changes in mothers' attributions over time. However, initial levels of mothers' attributions of oppositional child behavior to internal, stable, and global causes positively predicted child oppositional behavior, controlling for ADHD versus nonproblem status and the child's initial level of oppositional behavior. Although initial levels of overreactive and nonresponsive parenting also positively predicted child oppositional behavior, the contribution of mothers' attributions remained significant even with parenting variables controlled. Results suggest that mothers' attributions of child oppositional behavior to internal, stable, and global causes may contribute to maintenance of child problems over time and that these parenting cognitions have importance as intervention targets.

Fifteen children with ADHD aged 8 to 12 years and age and gender matched controls performed two different stopping tasks to examine response performance and inhibition and their respective moment-to-moment variability. One task was the well-established stop-signal task, while the other was a novel tracking task where the children tracked a spaceship on the screen until an alarm indicated they should stop. Although performance was discrete in the stop signal task and continuous in the tracking task, in both tasks latencies to the stop signal were significantly slowed in children with ADHD. Go performance and variability did not significantly differ between ADHD and control children in either task. Importantly, stopping latency in the novel spaceship tracking task also was more variable in children with ADHD. As stopping variability cannot be measured using the standard stop signal task, the new task offers compelling support for the heretofore untested prediction that stopping is both slowed and more variable in children with ADHD. The results support a response inhibition impairment in ADHD, whilst limiting the extent of an intra-trial variability deficit.

In this article, the authors report the psychometric properties of a parent-completed rating scale based on the criteria for oppositional defiant disorder (ODD) in the Diagnostic and Statistical Manual of Mental Disorders— Fourth Edition—Text Revision ( DSM-IV-TR). Mothers of 294 boys and 48 girls with attention-deficit/hyperactivity disorder (ADHD) and 53 boys and 45 girls without behavior problems completed the Oppositional Defiant Disorder Rating Scale (ODDRS). Fathers of 44 boys with ADHD also completed the scale,and 71 mothers of boys with ADHD provided 1-year test—retest data.The ODDRS had high internal consistency, high interrater reliability, and moderate 1-year test—retest reliability.The scale had one principal component and correlated as expected with related subscales from the Child Behavior Checklist and with overreactive parenting. Scores were not significantly correlated with parent or child age or with socioeconomic status.The strong psychometric properties indicate that this measure holds considerable promise for briefly assessing ODD in a manner consistent with the DSM-IV-TR.
