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.
Dr) Sheffield gives his measure to his supervisor, who is also an expert in pathological gambling. His supervisor says that his measure appears to test all the components of pathological gambling, including feeling restless when attempting to stop gambling, jeopardizing jobs in order to keep gambling, and using gambling to escape from problems and a bad mood. Given this information, Dr. Sheffield's measure has evidence of which of the following?

Content validity refers to the extent to which a measure assesses all the relevant aspects or components of the construct being measured. In this case, Dr. Sheffield's measure appears to test all the components of pathological gambling that the supervisor identified, suggesting that it has content validity. Predictive validity refers to the extent to which a measure is able to predict future outcomes. Criterion validity refers to the extent to which a measure correlates with a relevant criterion (e.g., a gold standard measure or an established diagnosis). Discriminant validity refers to the extent to which a measure is able to accurately distinguish between the construct being measured and other constructs that it should not be related to. The scenario does not provide any information to suggest that Dr. Sheffield's measure has any of these validities.
