Uncertainty and Firearms: Obtaining Secure Storage

The goal of this clinical trial is to test whether inclusion of cognitive behavioral therapy (CBT) for Uncertainty-Enhanced (CUE) with Lethal Means Counseling (LMC) is acceptable, feasible, and efficacious in addressing secure firearm storage and associated psychological constructs in active duty servicemembers. The clinical trial aims to: * Assess the preliminary efficacy of a LMC intervention, augmented with CUE, on firearm storage practices * Examine mechanisms through which CUE and LMC increase firearm storage practices * Assess credibility and acceptability of LMC Participants will complete: * One baseline visit * Two intervention sessions-CUE and LMC * Six brief surveys per day for 28 days using a mobile application * One mid-point survey and five follow-up surveys
