Previous studies have looked at the structure of attention-deficit/hyperactivity disorder
(ADHD) using latent class analysis (LCA) of Child Behavior Checklist (CBCL) or Diagnostic …

OBJECTIVE: Genetic studies of attention-deficit/hyperactivity disorder (ADHD) generally use
discrete DSM-IV subtypes to define diagnostic status. To improve correspondence between …

OBJECTIVE: New attention-deficit/hyperactivity disorder (ADHD) subtypes identified through
latent class analysis have been recently proposed. Here, we assess the accuracy of simple …

Statistically based classification methods have successfully refined ADHD into homogenous
and heritable subtypes. External validity and impairment of these subtypes was examined …

Background: Previous efforts to subtype Attention‐Deficit/Hyperactivity Disorder (ADHD)
using latent class analysis (LCA) applied to DSM‐IV symptom profiles of adolescent female …

Compared the effectiveness of discriminating attention deficit/hyperactivity disorder (ADHD)
subtypes using the Parent Rating Scale (PRS) and Teacher Rating Scale (TRS) of the …

This study used latent profile modeling (LPA) with a community sample that included an
enriched sampling of children (aged 6–11) diagnosed with attention deficit/hyperactivity …

Background: Findings from family and twin‐based studies of Attention Deficit/Hyperactivity
Disorder (ADHD) have indicated that inattentive and combined subtypes cluster together …

Many twin studies on parental ratings of attention deficit hyperactivity disorder (ADHD)
symptoms report low or negative DZ correlations. The observed differences in MZ and DZ …

The genetic and environmental mediation of continuity and change in parent-reported
ADHD symptoms were investigated in a cohort of over 6000 twin pairs at 2, 3 and 4 years of …
