Participants
Participants included 64 children (49 boys, 15 girls) ranging in age from 7 to 12 years (mean = 9.17, SD = 1.40). They were selected from a pool of 201 children referred for psychiatric and psychoeducational assessment of learning or behavioral disorders to the outpatient clinic of the Department of Psychiatry at an urban pediatric hospital. Sample sizes for the ADHD-I and control groups were determined by the availability of valid actigraph data; such data were available for 20 children who
Actigraph Scores by ADHD Status
Using a 2 (testing session) by 3 (group status) repeated-measures design in which the ADHD factor was partitioned into orthogonal contrasts, we determined that the main effects of group status and testing session on overall activity were nonsignificant. However, there was a significant interaction indicating increased activity among children with ADHD and decreased activity among control participants in the afternoon testing session. The details of this analysis are reported in Table 2.

DISCUSSION
The results of this study are only partially consistent with expectations based on the definition of ADHD specified in the DSM-IV. In line with previous research involving actigraphy, children with ADHD were found to have higher levels of objectively measured activity than children not affected by the disorder, but only in the afternoon portion of the clinical diagnostic assessment. Furthermore, although DSM-IV criteria would lead clinicians to believe that children with ADHD-I should not

A review of objective assessments for hyperactivity in attention deficit hyperactivity disorder
2022, Journal of Neuroscience MethodsCitation Excerpt :ADHD is a highly heterogeneous disorder that can be divided into three presentations: predominantly inattentive type, predominantly hyperactive-impulsive type, and combined type (combination of inattentive and hyperactive-impulsive symptoms). According to the DSM-IV, children with the combined type of ADHD are more active than those with inattention, but Actigraph studies found no significant differences in hyperactivity between the inattentive and combined types (Dane et al., 2000; Dabkowska et al., 2007; Hartanto et al., 2016; Kofler et al., 2016). Similar to the above studies, no significant differences in hyperactivity were observed across the three ADHD subgroups (Miyahara et al., 2014).
