A 9-Year-Old Boy Is Brought to the Office After He

A 9-year-old boy is brought to the office after he refused to go to the school.  He has not gone to school for a few days, saying that he has a stomachache.  However, when it comes time for soccer practice, he has no physical symptoms.  When the pediatrician asks how things are going at school, the patient says, "kids laughed at me when the teacher said she couldn't read my homework."  His mother brings a recent report from the boy's teacher, which says that he is able to read and do math, but that when writing he fidgets a lot and stares out the window.  His writing is unclear, disorganized, and below the level of his peers.  His mother received a call from his teacher last week after the boy threw his writing book on the floor and began to cry.  Vital signs and physical examination, including abdominal examination, are normal.  At this time, which of the following is the most likely diagnosis in this patient?

A) Attention-deficit hyperactivity disorder
B) Language disorder
C) Mild intellectual disability
D) Oppositional defiant disorder
E) Social anxiety disorder
F) Somatic symptom disorder
G) Specific learning disorder
