“…The CLAM (Swanson et al 1995) is a 15-item scale completed by parents of ADHD and control children. It incorporates items from the IOWA Conners Rating Scale (Pelham et al 1989) and the Abbreviated Conners Rating Scale (Conners 1973), both of which are commonly used to assess ADHD behaviour. The SNAP (Swanson et al 1988) is a 23-item scale used to assess ADHD symptomatology at home and at school and was completed by parents of ADHD and control children.…”

Methylphenidate is the most common treatment for attention deficit hyperactivity disorder (ADHD) Attention deficit hyperactivity disorder (ADHD) is the most common pediatric psychiatric disorder (Swanson et al. 1995), with an estimated childhood prevalence of 9% in boys and 3% in girls (Szatmari et al. 1989). Surface symptoms of inattentiveness and impulsivity (Shue and Douglas 1992;Shaywitz and Shaywitz 1988) are often, though not invariably, accompanied by hyperactivity (Gittelman and Mannuzza 1985). ADHD is highly heterogeneous with several distinct subtypes and often comorbid with learning, anxiety, and conduct problems. During childhood, ADHD is associated with greater risk of low academic achievement, grade failure, delinquency (Barkley 1997) and during adulthood, with psychiatric disorders and substance abuse (Wender 1987). Stimulant medication, primarily methylphenidate, is the most common treatment for ADHD. Because methylphenidate may be associated with altered neurotransmitter levels (Mefford and Potter 1989; Voeller 1991), several investigators have attributed ADHD to a neuroFrom the Novartis Pharmaceuticals Canada Inc., (GAS), Dorval, Quebec, Canada; and The Hospital for Sick Children, Divisions of Neurology (MAM, TH, WR, MJT) and Psychology Research (JR), Toronto, Ontario, Canada.Address correspondence to: Dr. Molly A.

Improved social skills and school performance have also been documented (e.g., Swanson et al. 1995). However, the optimal dosages have not yet been established and clinical anecdotal descriptions report some children as becoming overfocused, cognitively constricted, introverted, and "zombie-like" on higher doses (Swanson et al. 1991; Thurston et al. 1979). These descriptions are not consistently substantiated by empirical studies, however, which show both linear improvements with dose (Douglas et al. 1995;Solanto and Wender 1989) and adverse effects of high dose levels (Dyme et al. 1982;Malone et al. 1988;Sprague and Sleator 1977). A recent study by Tannock and Schachar (1992) has shown opposing effects of a high dose level at different test sessions with children making more perseverative errors in the first session and fewer in the second, while another study by this same group reported that despite clinical observations of overfocusing, measured attention performance was not affected by a high dose (Tannock et al. 1989).Children with ADHD are thought to have a primary attentional deficit in inhibitory (Barkley 1994;Schachar ...

“…Parents completed two rating scales: (1) the DBD rating scale (Oosterlaan, Scheres, Antrop, Roeyers, & Sergeant, 2000;Pelham, Gnagy, Greenslade, & Milich, 1992), a symptom severity rating scale containing four scales with the behavioral descriptors of AD/HD inattentive subtype, AD/HD hyperactiveimpulsive subtype, ODD as well as CD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association [APA], 1994) and (2) the Child Behavior Checklist (CBCL; Achenbach, 1991;Verhulst, Van der Ende, & Koot, 1996a). Teachers completed three rating scales: (1) the DBD, (2) the Teacher Report Form (TRF; Achenbach, 1991;Verhulst, Van der Ende, & Koot, 1996b) and (3) the IOWA Conners Teacher Rating Scale (IOWA CTRS; Oosterlaan, Prins, & Sergeant, 1992;Pelham, Milich, Murphy, & Murphy, 1989). The response rate for parents and teachers was 38.3% and 89.6%, respectively.…”

This study was aimed at (a) replicating findings of slow and variable response execution and slow response inhibition in Attention Deficit\Hyperactivity Disorder (AD\HD), (b) investigating whether these deficits are specifically related to AD\HD or may also be observed in Oppositional Defiant Disorder (ODD), and children comorbid for AD\HDjODD, and (c) examining the role of activation level in task performance of children with AD\HD. To meet these aims, the stop paradigm was administered at three levels of activation, using a slow, medium, and fast presentation rate of stimuli, to 4 groups of children : 24 AD\HD children, 21 children with ODD, 27 children with comorbid AD\HDjODD, and 41 normal controls. As hypothesized, children with AD\HD exhibited a slow response execution process with considerable variability in the speed of responding compared to normal controls. Slow response execution was also observed in the comorbid AD\HDjODD group but not in the pure ODD group. Larger variability in the speed of responding was common to all disruptive groups compared with controls. In contrast to our hypothesis, no group differences emerged for inhibitory functioning. Finally, the slow event rate condition caused a further deterioration in the speed of the response execution process in both the AD\HD group and ODD group.
