Quizplus · Accepted Answer

Rufus showed symptoms of conduct disorder at 8-9 years old, which is before the age of 10. Therefore, he would be diagnosed with CD, Childhood-Onset Type. ODD is not a correct diagnosis as Rufus meets the criteria for CD. CD, Adolescent-Onset Type would not be possible as Rufus showed symptoms before the age of 10. A "No diagnosis" option is not valid in this scenario as Rufus has been diagnosed with CD.
