These findings add to the growing body of evidence that firearm-related behaviors, beyond just gun ownership, may influence suicide risk, and support the most evidence-based and conceptually sound recommendation for suicide prevention, which is to remove the firearm from the home.
There are some limitations to this study. For example, the validity of the “psychological autopsy” approach used in the study has not been determined, and there is also a question mark over the accuracy of family members’ reports about gun ownership and storage practices. Despite this, the study provides support for recommendations for a change in firearm behaviors to reduce the risk of suicide.
