Key improvements to the Army's suicide prevention and intervention training: An interagency collaboration to develop the new "ACE Base +1" curriculum

Abstract: Introduction: Suicide is a prevalent problem impacting the military community. The U.S. Army recognized the need to address this complex issue; one line of effort has been to provide suicide prevention and intervention education and training that is informed by current research, doctrine, and implementation best practices. The purpose of this article is to outline and present the genesis of the Army's new suicide prevention and intervention training—"Ask, Care, Escort (ACE) Base +1"—that aligns with the DoD newly published regulation-driven initiatives. Materials and Methods: The development of the "ACE Base +1" curriculum was a collaborative effort between two organizations within the Defense Health Agency: The Defense Centers for Public Health-Aberdeen and the WRAIR. A multidisciplinary team was formed by selecting specific operational and subject-matter experts from each organization based on educational qualifications and practical experiences expected to aid the development of curriculum content (e.g. subject-matter experts) and/or the training design. Revisions to the curriculum were informed by the Army's existing suicide prevention training module, current research in suicide prevention and public health, updated and relevant Army regulations, and current public health policy guidance from the CDC and the Department of Suicide Prevention Office. A detailed account of the systematic and iterative curriculum development process is provided. Results and Conclusions: 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.
