RESEARCH STUDY 5.1 Dr. Valencia is considering conducting a study examining whether narcissistic people have poorer social interactions than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Mayo scale. Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special." Refer to Research Study 5.1 to answer the following seven questions Dr. Valencia calculates a correlation coefficient (r) to examine the relationship between Question 1 and Question 2 and between Question 1 and Question 3. She finds a correlation coefficient of r = −0.73 between Questions 1 and 2 and a correlation coefficient of r = 0.74 between Questions 1 and 3. Which of the following is true of her findings? a. There appears to be good internal reliability in the scale. b. The correlation between Questions 1 and 2 and Questions 1 and 3 are in the same direction. c.

RESEARCH STUDY 5.2 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 5.2 to answer the following nine questions. 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? a. Content validity b. Predictive validity c. Criterion validity d. Discriminant validity

RESEARCH STUDY 5.2 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 5.2 to answer the following nine questions. 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? a. Face validity b. Content validity c. Criterion validity d. Discriminant validity
C

RESEARCH STUDY 5.1 Dr. Valencia is considering conducting a study examining whether narcissistic people have poorer social interactions than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Mayo scale. Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special." Refer to Research Study 5.1 to answer the following seven questions Before using the measure in her study, Dr. Valencia gives the measure to a group of students on Tuesday. She gives the measure to them again on Thursday. Dr. Valencia is examining the scatterplot of the data she collected on day 1 and day 2. On the scatterplot, she sees that the dots are very close to forming a diagonal line. This indicates which of the following? a. A strong relationship b. A nonrelationship c. A valid finding d. A negative finding
A
Which of the following is true? a. The confidence people have in their memories is not strongly related to the accuracy of their memory. b.
