First of all, I can’t believe there’s another Moulton that does ADHD research. There aren’t that many Moultons out there…although I started a Facebook group for Moultons, and there are about 150 of us so far.
Anyways, Dr. John Moulton and his team studied whether having childhood ADHD contributed to developing Conduct Disorder (CD) in adolescence. The researchers found that, compared to a control group, having ADHD did, in fact, increase the chances of developing CD in adolescence. In addition, even if a child had low scores on a measure of CD and ODD symptoms, it still had significance in developing CD in adolescence.
