The parents of a toddler are concerned about a recent increase in the frequency, intensity and duration of the child's temper tantrums. The parents report that the toddler gets on the floor, kicks and screams when they set limits. The child's health and developmental history is unremarkable. Family history is significant for mood and anxiety disorders on the mother's side, and attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) on the father's side. Which of the following would be the most appropriate step for the psychiatrist to take next?
A. Administer a Denver developmental screening test to the child.
B. Explore the parents' concerns about seemingly normal behavior.
C. Inquire about early separations and traumatic events in the child's life.
D. Administer an inventory to assess the parenting style of each parent.
E. Begin parent psychoeducation about ADHD and oppositional defiant disorder
