Project Safe Guard-Trauma

The goal of this randomized controlled trial is to determine if a counseling intervention, Project Safe Guard-Trauma (PSG-T), increases secure firearm storage practices in adults who screen positive for posttraumatic stress disorder (PTSD). The main questions this study aims to answer are: * Does PSG-T lead to more secure firearm storage practices? * Does PSG-T increase knowledge about the link between firearm storage practices and suicide risk? * Does PSG-T increase intentions to store firearms securely? Researchers will compare PSG-T to a control, Project Safe Guard (PSG), which is a counseling intervention that does not focus on the potential influence of PTSD symptoms on firearm storage practices. This will help to determine if PSG-T works better than PSG to increase secure firearm storage in adults with elevated PTSD symptoms. Participants will: * Complete a baseline survey * Receive the counseling intervention * Complete a survey immediately after the intervention and at 1-, 3-, and 6-months following the intervention
