A researcher developed a questionnaire to assess impulsiveness among adults. In a journal article, she later presented evidence that college students tend to get essentially the same score if they take the test twice, two months apart. However, when a reader looks at the sample questionnaire items she included in the article, it seems that they relate more to whether a person is sociable, outgoing, and fun than to whether an individual is impulsive. In this situation, the reader is most likely to specifically question the ________ of the researcher's questionnaire.
A. reliability
B. validity
C. generalizability
D. norm
