Gun-Related Beliefs as Predictors of Gun Policy Support: Findings from the Nationally Representative GRIP Survey.

Partisan affiliations and other demographic characteristics inadequately explain support for gun policy and provide vague public health messaging guidance. Gun-related beliefs may be more malleable and meaningful determinants of policy support for gun violence prevention. Using a nationally representative, community-engaged, mixed methods design, we examined predictive associations between gun-related beliefs and public support for six gun policies (i.e., universal background checks, waiting periods, minimum purchasing age, violent offender prohibitions, concealed carry permits, and extreme risk protection orders (ERPOs)). Gun-related beliefs were more strongly associated with policy support than political affiliation. Strength of agreement with "no one should own AR-15 style semiautomatic rifles" was positively associated with support for all six policies. Beliefs about gun policies as violence prevention were also highly salient, predicting support for five policies, with disagreement or agreement both predicting higher probability of support for universal background checks, violent offender prohibitions, and ERPOs than neutral beliefs. Beliefs that "guns are tools" were generally unassociated with policy views. Findings suggest potential for gun violence prevention messages that combine values-based language with salient themes to build support for preventive policies across political and demographic lines.
