Combining Parent and Child Training for Young Children with ADHD
One effective means of preventing early-onset conduct disorder (CD) may be to target preschool children with ADHD before more serious conduct problems have escalated. Unfortunately, one limitation of the ADHD treatment-outcome literature is that comparatively little research has been conducted with samples of children under age seven.
Although research indicates that methylphenidate and other psychostimulants are effective in reducing core ADHD symptoms such as inattention and distractibility among preschoolers (see e.g., Connor, 2002), there is little evidence to suggest that these medications prevent the escalation of ADHD to ODD and CD in later childhood or adolescence
