Final answer:
The main difference between Clive, a clinical psychologist, and Julianna, a psychiatrist, is that clinical psychologists can administer therapy and psychological assessments but cannot prescribe medications, while psychiatrists can both prescribe medications and conduct therapy.
Step-by-step explanation:
The primary difference between Clive, a clinical psychologist, and his sister Julianna, a psychiatrist, lies in their education and scope of practice. Clinical psychologists typically have a PhD or PsyD and their work centers around diagnosing and treating psychological disorders through therapy and psychological assessments. They may complete postdoctoral work and must pass a licensure exam to practice. Clinical psychologists cannot prescribe medication. On the other hand, psychiatrists have a Doctor of Medicine (MD) degree allowing them to prescribe medications alongside conducting therapy, which can be essential for treating certain mental health conditions that require pharmacological intervention.
