Multiple Choice
Dr. Delmonte develops a questionnaire to assess the personality trait of impulsivity among adults. In a journal article, she presents evidence that college students tend to get essentially the same score if they take the test twice, 2 months apart. However, when a reviewer examines the sample questionnaire items included in the article, it seems that they relate more to whether a person is sociable, outgoing, and fun-loving than to whether an individual is impulsive. Dr. Delmonte's questionnaire may lack:
A) test-retest reliability.
B) objectivity.
C) validity.
D) interrater reliability.
