Key Improvements to the Army's Suicide Prevention and Intervention Training: An Interagency Collaboration to Develop the New "ACE Base +1" Curriculum.

The interagency collaborative efforts resulted in a suite of training products, "ACE Base +1" version 1.3 that is modernized in training content, delivery methods, and design. Four primary elements shaped the final products: (1) A modular framework allowing a tailored approach to mandatory training, (2) a public-health approach that focuses on earlier intervention opportunities while building trust and cohesion, (3) a training design centered on peer discussions and behavioral rehearsal, and (4) an expansion of the curriculum to be inclusive of the entire Army community. Practical implications for each element are discussed.As the program of record, "ACE Base +1" training satisfies the annual requirement for all Active Army, Army National Guard, U.S. Army Reserve, and Department of the Army (DA) civilians. Both the training content (e.g., public-health concepts) and design of "ACE Base +1" reflect a comprehensive approach, focused on developing concrete, applicable skills that support the shared responsibility to suicide prevention and intervention. Limitations, such as delayed interagency collaboration and time constraints, are discussed. Future directions include recommendations for future curriculum projects, specifically within military populations, such as interprofessional, interagency collaboration, and selecting a multidisciplinary team of subject-matter experts. Additionally, WRAIR plans to continue their support to Directorate of Prevention, Resilience and Readiness with the expansion of the +1 menu of trainings, ongoing program evaluation, and longitudinal analysis to inform future revisions and ensure the content and delivery methods remain modernized, relevant, and effective.
