This question is missing the options. I've found the complete question online. It is as follows:
Dr. Peterson has collected clinical observations, neurological test data, psychological test scores, and interview material on Mrs. Davis. If Dr. Peterson is doing this for the purpose of drawing conclusions that will lead to a diagnosis of Mrs. Davis, we can infer that Dr. Peterson is ____
a. a psychoanalyst
b. using reliable and valid measures
c. doing an assessment
d. using the DSM-5
Answer:
We can infer Dr. Peterson is c. doing an assessment.
Explanation:
We have been told that Dr. Peterson has collected several types of data on Mrs. Davis with the purpose of drawing a conclusion that will lead to a diagnosis. That information is consistent with an assessment, which is the gathering of information via different means - interviews, observations, testing, etc. - in order to develop a diagnosis of the subject. The goal is basically to explain and even predict future behaviors by the subject.
