NURS 5366 MODULE 1 QUIZ. Question 1 Hospital nurses are observed in order to determine exactly how long nurses swab IV ports with alcohol. Because they are being observed, they “scrub the hub” longer than they ordinarily would have. This is an example of what threat to validity of the the study design relevant to quantitative research? Answers a. Control b. Bias c. Hawthorne effect d. Inaccurate operationalization of variables Response Feedback: Subjects’ knowledge of a study could influence their behavior and possibly alter the research outcomes. This threatens the validity or accuracy of the study design. An example of this type of threat to design validity is the Hawthorne effect, which was identified during the classic experiment at the Hawthorne plant of the Western Electric Company during the 1920s and 1930s. The employees at this plant exhibited a particular psychological response when they became research participants: they changed their behavior simply because they were subjects in a study, not because of the research treatment.
