Association between gun owner attitudes and their behavior in private firearm sales.

Federal law places no regulations on unlicensed, private firearm sellers. However, a majority of the firearms used in crime come from these unregulated markets. This study aims to characterize the demographics of gun owners who engage in private sales, determine how often these individuals engage in selling behaviors, and ascertain whether sellers' attitudes are associated with their reported behaviors in the private market. A nationally representative web-based survey of 1444 gun owners, fielded in Spring 2016, were asked about their participation in the private market. The 238 respondents who participated in the private market were asked about their behavior on their last sale and the extent to which they felt it was the responsibility of sellers to ensure purchasers were legally able to own a firearm. Less than half of private gun sellers agreed that it is the seller's responsibility to ensure purchasers are eligible to buy guns (46%). Among private sellers, only 44% checked purchasers for eligibility and 32% denied a sale due to concerns about whether the firearm would be used safely. Sellers who agreed it was their responsibility to ensure purchasers were eligible to buy a gun had 4.52 (95% CI:1.78 to 11.5) times greater odds of reporting checking for a permit or conduct a background check on their last sale. it. These findings suggest a need for strategies to increase gun sellers' perceptions of responsibility for ensuring only eligible purchasers purchase guns, potentially including communication campaigns or educational programs.
