| Sumario: | To assess acceptability, feasibility, and appropriateness, change in knowledge, and expertise among participants who enrolled in a Dissemination and Implementation Science (D&I) training. The design-focus framework, theory of planned behavior, and Validated D&I competences developed the training's learning strategies, course materials and structure. Nutrition undergraduate students at an Appalachian University. An eight-week, online training met once a week for an hour via Zoom. Students completed case studies, discussions, and developed an implementation plan for an evidence-based nutrition program to improve students understanding and expertise in implementation science. A 40-item pre survey and 42-item post survey were used to test if self-efficacy and expertise change after intervention and Implementation Outcomes to identify feasibility intervention. A two-tailed Wilcoxon-signed rank test assessed significance in mean differences. Qualitative exit interviews were thematically analyzed and categorized with quantitative results for Implementation Outcomes (5-pt) and Kirkpatrick Learning measures (10-pt). Knowledge scores (n=8) were significantly higher after the intervention (6.75 ± 0.68) compared to before (4.13 ± 0.68), p= 0.0234, and supported by the Kirkpatrick Scale quantitative (mean scores between 6.94 ± 1.7 (Learning),7.35 ± 1.9 (Reaction)) and qualitative findings. Expertise rankings were significantly higher after the intervention (3.14 ± 0.29) compared to before (1.86 ± 0.29), p=0.0313. Qualitative results align with the validated psychometric Implementation Outcome findings (3.59 ± 1.26, appropriateness score 3.94 ± 0.85, feasibility score of 4.09 ± 0.67) and support continued implementation of the training. The absence of nutrition-focused D&I science training created a capacity barrier in nutrition, which hindered ability to evaluate implementation of interventions. This pilot study suggests that a nutrition-specific D&I science training increased knowledge and expertise among participants; and implementation outcomes suggest that this approach is feasible, acceptable, and appropriate resource to build knowledge and expertise in nutrition D&I science. This provides a feasible, acceptable, and appropriate resource for nutrition to build knowledge and expertise in D&I science. None
