The Impact of Individual Mentored Career Development (K) Awards on the Research Trajectories of Early-Career Scientists.

ABSTRACT

PURPOSE: This analysis examined the role of a National Institutes of Health (NIH) individual Mentored Career Development Award (K01, K08, K23) on launching and sustaining independent research careers for early-career scientists, and investigated the effects of these awards during and after the doubling of the NIH budget. METHOD: The authors used grants data from the NIH covering the period 1990 through 2016, and compared success in receipt of R01 equivalent awards (R01 Eq.) and Research Project Grants (RPGs) for K awardees and K applicants who did not receive funding. The analysis combined regression discontinuity design with coarsened exact matching, and regression. RESULTS: Overall, receipt of K award was associated with a 24.1% increase in likelihood of first independent NIH award (P < .01), and a larger number of R01 Eq. and RPG awards. After accounting for first major independent awards, K awards were uncorrelated with receiving second major independent research awards. Comparing different funding periods, K01 awards were predictive of subsequent R01 Eq. and RPG awards after but not during the NIH doubling, K08 awards were predictive only during the NIH doubling, and K23 awards were predictive during both periods. CONCLUSIONS: Receipt of Mentored Career Development Awards was linked to increased likelihood that early-career scientists successfully transitioned to an independent research career. These findings indicate that extending funding to additional K award applicants with meritorious scores could significantly strengthen the pipeline of biomedical researchers. In addition, enhancing K awards may be relevant to sustaining research careers for clinician scientists.
