Reciprocal relations between dimensions of attention‐deficit/hyperactivity and anxiety disorders from preschool age to adolescence: sex differences in a birth cohort sample

Symptoms of anxiety and attention-deficit/hyperactivity disorder (ADHD) are prospectively related from childhood to adolescence. However, whether the two dimensions of ADHD-inattention and hyperactivity-impulsivity-are differentially related to anxiety and whether there are developmental and sex/gender differences in these relations are unknown.
