Multiple Choice
A researcher 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. When you look at the sample questionnaire items she included in the article, though, it seems that they relate more to whether a person is sociable, outgoing, and fun than to whether an individual is impulsive. You are questioning the __________ of the researcher's questionnaire.
A) objectivity
B) reliability
C) external validity
D) construct validity
