Questions in This Drill

1. Over the past year, a 22-year-old college student has become increasingly withdrawn. He tells his roommate that a government agency is transmitting messages to him through the campus Wi-Fi, and he sometimes speaks in sentences that start on one topic and end on an unrelated one. He has also stopped showering regularly and shows little emotional expression in conversations. Which combination of symptom types is present in this presentation?
2. Which of the following best distinguishes obsessive-compulsive personality disorder (OCPD) from obsessive-compulsive disorder (OCD)?
3. A child psychologist evaluates a 7-year-old who has difficulty sustaining attention during schoolwork, frequently interrupts peers, struggles to stay seated during group activities, and often loses materials needed for tasks. Symptoms have been present since at least age 5, occur both at home and at school, and cause significant difficulty in daily functioning. Which category of psychological disorder best fits?

Which of the following would most strongly support the claim that schizophrenia has a larger genetic component than antisocial personality disorder?
5. The table below shows concordance rates (the probability that the second twin has the disorder given that the first one does) for four disorders:

   Schizophrenia	48%	17%
   Bipolar I disorder	40%	7%
