Study Designs: Statistics (Multiple Choice Question)

[Joystar77]

The investigators suspect that military men may not tell the truth about visiting a CSW. Some may say they did visit a CSW when they actually did not; others will say they did not visit a CSW when they actually did. Is this:

A. Nondifferential misclassification of exposure

B. Nondifferential misclassification of disease

C. Information bias

D. Selection bias

Is the answer to this d-Selection bias, because of the fact that only military men were selected and not military women? If this is not correct, then can someone please help me.

The correct answer is C. Information bias. This is because the investigators suspect that the participants may not be providing accurate information about their exposure (visiting a CSW) and this can bias the results of the study. Selection bias refers to the systematic differences between the selected study participants and the target population, which can affect the generalizability of the results. In this case, the investigators are concerned about the accuracy of the information provided by the selected participants, rather than the representativeness of the sample.
