Answer 1

1. Coverage
2. descriptive/content validity
3. Predictive validity
4. Discriminant validity
5. Interrater reliability (consistency)
6. Test-retest reliability
7. Sensitivity
8. Specificity

Question 2

What is coverage?

Answer 2

A good classification being able to classify everything that needs to be classified. If it is something that has already been discovered. then it has good coverage.

Question 3

What is descriptive/content validity?

Question 5

What is discriminant validity?

Answer 5

Things can’t be two places in the classification system. It has to fit in one class or the other.

Question 6

What is interrater reliability?

Answer 6

When two people can classify something the same way. If two people disagree on something, it would be fault of the classification system.

Question 7

Test-retest reliability

Answer 7

When there is consistency over time. If we classify things one way today, six months from now we classify it the same way.

Question 8

What is sensitivity?

Answer 8

If there is a set of behavior that fit the 5 D’s, the classification system should be able to detect the disorder and give a name for it. The classification system should be sensitive enough to classify it as a disorder.

Question 9

What is specificity?

Answer 9

If something is not a disorder, it shouldn’t be in the classification system. The ability for a classification system to know when there isn’t a disorder.

Question 10

What is a true positive?

Answer 10

It’s when a disorder and the classification system said it was a disorder.

Question 11

What is a true negative?

Answer 11

When it’s not a disorder and the classification system did not call it a disorder.

Question 12

What is a false positive?

Answer 12

When it’s not a disorder but the system says that it was a disorder.

Question 13

What is a false negative?

Answer 13

When there is a disorder but the classification system says that there wasn’t.

Question 14

What is epdemiology?

Answer 14

To know how many people have a certain disorder or illness. This would be epidemiological research.

Question 15

What is prevalence?

Answer 15
