Project Safe Guard-Trauma

Description

Firearms are the most common suicide method among service members, veterans, and civilians. Secure firearm storage reduces the risk of suicide. Lethal means safety counseling (LMSC) is an effective approach to promote secure firearm storage and, therefore, decrease the risk of suicide. Suicide risk is elevated among individuals with posttraumatic stress disorder (PTSD). PTSD affects safety perceptions and firearm storage practices. Current data indicate that the gold standard existing LMSC intervention – Project Safe Guard (PSG) – has reduced efficacy for individuals with elevated PTSD symptoms. Thus, there is a need to adapt LMSC for individuals with elevated PTSD symptoms.

Project Safe Guard-Trauma (PSG-T) is a brief LMSC intervention rooted in PSG principles but adapted specifically for firearm-owning individuals with PTSD. This study will evaluate the efficacy of PSG-T compared with control (standard PSG) in prompting more secure firearm storage behaviors. This study is a 2-arm randomized controlled trial. Participants will be randomized following the pre-intervention assessment. The participants will receive a single-session LMSC intervention, post-intervention assessment, and 1-, 3-, and 6- month follow-up assessments. The goal is to increase knowledge about the link between firearm storage practices and suicide risk, intentions to store firearms safely, and actual safer firearm storage behaviors.

Aim 1: To conduct a 2-armed randomized control trial to evaluate the efficacy of PSG-T compared with a control (PSG) in increasing knowledge about the link between firearm storage practices and suicide risk, intentions to store firearms safely, and actual safer firearm storage behaviors.

Hypothesis 1: Compared with PSG, at 1-, 3-, and 6-month follow-up, PSG-T will result in greater (a) knowledge about the link between firearm storage practices and suicide risk, (b) intentions to store firearms securely, and (c) actual more secure firearm storage behaviors (primary outcome at 6-month follow-up).

Aim 2: To evaluate differences in PTSD-related negative cognitions about the world as a potential mechanism of change in PSG-T for increasing knowledge, intentions, and behaviors regarding safe firearm storage practices.

Hypothesis 2: Participants who receive PSG-T will report fewer PTSD-related negative cognitions about the world compared with participants who receive PSG, and these decreases will be associated with increases in (a) knowledge about the link between firearm storage practices and suicide risk, (b) intentions to store firearms securely, and (c) actual more secure firearm storage behaviors.
