The moderating role of sex and self-, teacher-, and father-reported ADHD hyperactivity-impulsivity symptoms, on the association between early adolescent internalizing symptoms and substance use

CONCLUSIONS: Findings aid in clarifying the inconsistent relationship between internalizing symptoms and SU among adolescent females by underscoring the moderating role of ADHD-HI. Further, findings also support a growing body of literature which highlights the need for both self- and adult-informants (i.e., teacher and parent) in assessing ADHD-HI symptoms in females.
