Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as
being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. To test his measure, Dr. Sheffield gives his measure to a group of his clients and at the same time measures how many times they have been gambling in the past month. He predicts that clients who score higher on his measure will also report gambling more times in the past month. This procedure is meant to provide evidence for which of the following? Criterion validity T/F
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.
It's often impossible to repeat trials on the same subjects. 2-Subjects may report an inaccurate medical history. 3-It can be difficult to control all possible variables. 4-It's impossible to come up with testable scientific questions for human subjects.
