After giving all your patients a mental status exam that you designed, you assign them a DSM-5 diagnosis based on its outcome. Later, when you have seen the patients for a number of sessions and run them through a series of assessments, you find that your initial diagnosis based on your mental status exam and your final diagnosis have a high positive correlation. This might indicate that the mental status exam has:

a.

High validity

b.

Low reliability

c.

Low validity and low reliability

d.

High validity and high reliability
