i just need points

Explanation:

1. A. Validity

In research, validity refers to  whether the study actually represent the real life situation in its claim.

If the questions do not related to pathological gambling in any sense, the conclusion from the study would stray away from the actual cause that might influence the gambling. This make the data from the study cannot be used in any way or form to draw a conclusion.

2. A. Content validity

Content validity refers to whether the researchers have include all measures that could possibly influence the result  of the research. Content validity must exist to ensure that the researchers could make the best possible conclusion  for the phenomenons that occurs during the researches.

3. C. Known-groups paradigm

Known-groups paradigm refers to a situation where the researchers could ensure the validity of a certain research by including the group that they can control/discriminate. This group tend to filled with subjects with the same characteristic that can influence the result of the research.

4. B. Criterion validity.

Criterion validity commonly consist of  predictive validity and concurrent validity. Concurrent validity is used to create a comparison among the measurements and outcome created by the measurement at the same time. Predictive validity on the other hand   is used to create a comparison among the measurements and outcome created by the measurement that occurs later in the future.

Content validity

Explanation:

Content validity is an important research methodology term that refers to how well a test measures the behavior for which it is intended. It reflects how well a test is measuring a quality or skill that is related to a certain job.

Dr. Sheffield's measure is not strongly correlated with a measure of impulsivity.

Explanation:

Discriminant Validity is a term used in the field of psychology which tests if a specific concept or measurement that are not meant to be related are actually unrelated. Therefore based on the information provided within the question it can be said that Dr. Sheffield's measure is not strongly correlated with a measure of impulsivity.

I believe the answer is: Known-groups paradigm

A study is considered to have Known-groups paradigm if the researchers understand that the measure that they take will discriminate a certain groujp of subjects because of their known behavior.

From the case above Dr. Sheffield create a test to determine whether the subject unable to resist impulses to gamble.

The subjects that he use is a group of ex-gamblers who acknowledge they have a gambling problem (gamblers anonymous) and a group of ex-alcoholic who acknowledge they have drinking problem (AA).  We can say with high certainty that dr. Sheffield knew really well that people on GA will have higher scores. He just want to how big is the difference compared to the scores from AA group.

True

Explanation:

In a criterion validity test, the results of the test are correlated with the outcomes in future. In this study, the measures of gambling is used to depict the possible outcomes. If the clients tested on gambling measure score high, then it gives the relation of their gambling frequency in past.  

It is a predictive validity type of criterion validity test in which it is estimated that how likely the test or measure score can depict the future or past behaviour of the client.

Thus it is true

What Dr. Sheffield is doing is testing the validity of the psychological measurement of pathological gambling. The validity testing that he is engaging in is called criterion validity. Criterion-based validity is a type of validity where you test the constructed measurement’s validity against a criterion that has been proven to have a relationship with the measured variable.

In this case, Dr. Sheffield’s testing of his measurement on people who are in gambling anonymous vs. people who are in alcoholics anonymous and the subsequent result shows that his measurement can be used to measure the pathological gambling variable since high scorers for his measurement can be found only in the people who are in the gambling anonymous group.
