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. Refer to Research Study 3.2 to answer the following five questions. To test his measure, Dr. Sheffield gives his measure to a group of people in Gamblers Anonymous (GA) and another group in Alcoholics Anonymous (AA). He finds that people in the GA group have higher scores on his new measure than people in the AA group. Why did Dr. Sheffield do this

When Dr. Sheffield presents the questionnaire that he created for the group of Alcoholics Anonymous, he wants to use people who, in fact, have some kind of addiction that damages their normal lives. In this case, with the answers of the Anonymous Alcoholics he is able to establish a comparison criterion for the answers of the Anonymous Players. In this case, with the highest score of Anonymous Players, he is able to present justifications for the addiction to games and show that this element is able to increase the results of the Anonymous Players, because the questions about the games affect them more than those who have an addiction in alcohol.
