Effective evaluation starts with clear frameworks that link program activities to measurable outcomes. This poster introduces demonstrated and practical ways for leveraging logic models to design, implement, and evaluate mental health and suicide prevention programs within the federal health sector. Drawing from multiple large-scale evaluation initiatives, our content will detail how logic models clarify inputs, activities, outputs, and intended outcomes. This clarity will create a shared understanding among interest-holders and guiding both formative and summative assessments. The poster will offer an overview of logic models, describing their core concepts and utility in the federal health context. Visual diagrams and explanatory text will show how logic models translate broad program goals—such as reducing suicide risk, increasing help-seeking, or improving access to care—into well-structured, operational plans. Stepwise, actionable guidance will walk audience members through developing a logic model: defining program objectives, mapping out resources, specifying activities and outputs, and selecting relevant impact metrics. A core section brings these elements to life through an application inspired by postvention initiatives in military and first responder settings, demonstrating how to organize support for communities dealing with recent suicide loss. This will emphasize stakeholder engagement, cultural sensitivity, and practical adaptation to fit different settings. The poster will also summarize leading practices for aligning evaluation questions and metrics to each model component, supporting responsive monitoring and ongoing program refinement. Key lessons learned include reinforcing the importance of tailoring logic models to specific population needs, maintaining a balance between comprehensiveness and usability, and cultivating shared ownership among all program contributors. Visuals depict both simplified and real-world logic model versions to accommodate every level of experience. To maximize real-world impact, the poster will equip the audience with practical take-home tools, including a logic model template and checklist along with tips to avoid pitfalls and encourage organizational buy-in. Audience members will leave with actionable knowledge and transferable resources for adaptation for new or existing teams advancing suicide prevention, mental health, or related federal health initiatives.
