A 23-year-old man presents to an outpatient psychiatrist complaining of anxiety and a persistent feeling that “something terrible will happen to my family.” He describes 1 year of vague, disturbing thoughts about his family members contracting a “horrible disease” or dying in an accident.

APsychodynamic psychotherapy and citalopram
BCognitive behavioral therapy and haloperidol
