Final answer:
Clinical psychologists differ from psychiatrists in that they cannot prescribe medication, which is something that only psychiatrists with a medical degree (MD) can do.
Step-by-step explanation:
The main difference between clinical psychologists and psychiatrists is in their ability to prescribe medication. Clinical psychologists, who have either a PhD or a PsyD, can administer and interpret psychological tests such as personality tests and intelligence tests. They focus on the diagnosis and treatment of psychological disorders and utilize various methods like talk therapy, cognitive-behavioral therapy (CBT), and they may also use tests like the MMPI (Minnesota Multiphasic Personality Inventory). However, they cannot prescribe medication. On the other hand, psychiatrists have completed medical school and have an MD (Doctor of Medicine) which allows them to prescribe medication in addition to conducting therapy.
Therefore, the answer to the student's question is: clinical psychologists differ from psychiatrists in whether or not they can give their clients medication (option c).
