The goal of the Life Force study is to (1) evaluate the efficacy of targeted, skills-based training for enhancing mental toughness and mitigating harmful and high-risk behaviors in active-duty Soldiers, and (2) to determine who benefits the most from this type of training. Researchers will compare the training group to a control group. All participants will complete a baseline survey and two follow up surveys at 6 and 12 months post-baseline. The group assigned to the Life Force training condition will also complete a 5-session, group-based, skills training program.

This study will evaluate the effectiveness of the Life Force training program, a 5- session, group-based, skills training program tailored specifically for active-duty Soldiers. The program uses evidence-based strategies to mitigate harmful and high-risk behaviors and promote Mental Toughness-defined as the ability to maintain peak performance under pressure or adversity, recover from setbacks, cope effectively with challenges, maintain a positive attitude, and persevere towards goals. The training sessions are led by skilled Life Force trainers from the study team and focus on building the following skills:

• Grow Through Support - building the inner circle and recognizing when to lean on that support
• Relentlessness - mastering the ability to push forward past the point of quitting
• Invite Adversity - fail forward, seeing failure as an opportunity for growth
• Nonstop Resolve - owning the setback, taking accountability of mistakes to reset and move forward
• Dominate Your Emotions - controlling emotions, breaking down intervention points and how to respond instead of reacting Participants will complete a 15-20 minute baseline survey. An AI machine learning algorithm, built from existing military administrative and health records, will be used to determine eligibility for participation by predicting who will benefit most from this training. Eligible participants will be randomly assigned to either the Life Force training or a control group. The training group will participate in 5 group training sessions. Both the training and control groups will complete two 15-20 minute follow-up surveys at 6 and 12 months. The surveys will assess for the occurrence of high-risk behaviors or events qualified for an Army Serious Incident Report (SIR), indicators of poor performance, and self-reported improvements in mental toughness, military readiness, job satisfaction, career intentions, and overall functioning in their occupational, personal, and social lives. Training group data will be compared to the control group (who will only complete the surveys).
