PROJECT SUMMARY for ADMINISTRATIVE SUPPLEMENT This supplement (Administrative Supplements to Promote Research Continuity and Retention of NIH Mentored Career Development (K) Award Recipients and Scholars; NOT-OD-20-54) accompanies Parent K08AA028543 (PI: Helle) and requests supplementary support in the form of additional research staff to promote the continuity of research during PI Helle’s time-limited period of leave. The 5-year parent K08 includes career development training and research aims evaluating the College Alcohol Intervention Matrix (CollegeAIM; NIAAA, 2015a; 2019). CollegeAIM was created to help college campuses select evidence-based alcohol reduction strategies (EBSs) to implement on their respective campuses. Despite NIAAA prioritization, the availability of the CollegeAIM tool, and several existing EBSs for risky drinking, relatively little is known about the adoption and implementation of EBSs for college drinking among stakeholders, and further, to what extent CollegeAIM is used to identify EBSs for implementation. The parent K08 evaluates the use and effectiveness of CollegeAIM in the selection of EBSs for college student drinking across a statewide substance use coalition, with a long-term objective of supporting colleges’ use of CollegeAIM and thus, ultimately the implementation of EBSs to reduce risky drinking. The project aims are being achieved via a mixed-methods design to: assess stakeholders’ use and perspectives of the CollegeAIM tool; identify barriers and facilitators to CollegeAIM use; and identify institution characteristics that impact CollegeAIM use. This is the first study to extensively evaluate CollegeAIM as a tool to identify EBSs on college campuses and will be instrumental in developing an organizational decision-support program, intended to be used in tandem with CollegeAIM to address college drinking. PI Helle is mentored by Drs. Kenneth Sher and Kristin Hawley (University of Missouri) and an excellent team of collaborators who support PI Helle’s advancement through specialized training in addictions and implementation science, including mixed-methods design and analytic approaches and alcohol prevention research. The mentored training is essential to establish PI Helle as an independent investigator in addiction implementation science and to extend the initiatives of the current study in future R-series proposals. Supplemental support in the form of salary and equipment for a full-time research specialist is requested to promote research continuity during the time-limited period of leave. To date, PI Helle’s parent K08 project and training is on track with the original timeline and the requested supplemental support will ensure continuation of the K08 timeline. The research specialist will coordinate and continue research activities (e.g., participant recruitment and enrollment, monitoring ongoing coding protocols) during PI Helle’s leave. This supplement will both support the parent K08 research and tr...
