Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships 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 Donal 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."
Before using the measure in her study, Dr. Rodriquez analyzes the data she gets from her students. She looks at the relationship between each of the individual questions. She sees that participants who agree with Question 1 also agree with Question 3 and disagree with Question 2. This is a test of which of the following?
A)Interrater reliability
B)Internal reliability
C)Test-retest reliability
D)Construct reliability

This is a test of internal reliability, specifically the degree to which the questions on the scale are measuring the same construct (i.e., narcissism). The fact that participants who agree with Question 1 also agree with Question 3 and disagree with Question 2 suggests that the questions are measuring the same underlying construct, and therefore have good internal reliability.
