The National Council for the Prevention of Violence (NCPV) has long recommended that primary care physicians screen for the presence of guns in the homes of their patients. The recommended screening question is, œDo you have any type of gun or firearm in the home where you live? Recently, the Council has recommended a second question be added to this original question. The second recommended question is, œDo you keep your firearm locked so that a key is required to access it? If patient™s response affirmatively to the first question and negatively to the second, the Council recommends that the physician spends a couple of minutes reviewing some of the key aspects of firearm safety. Materials for this discussion are provided free of charge on the Council™s website.
This change in recommendation by the Council is most likely to have what effect on the screening for potential gun violence?

A. Cannot be determined with any certainty from the information given
B. Decreased positive predictive value
C. Decreased sensitivity
D. Decreased specificity
E. Increased efficiency of the screening procedure
