title: The Association Between NIMH Funding and h-index in Psychiatry.
abstract: OBJECTIVE
  Academic productivity is measured under many domains: number of high impact publications, objective bibliometrics, securing extra-mural funding, etc. Citation impact is measured by an objective bibliometric called h-index. Securing funding from the National Institute of Mental Health (NIMH) is considered prestigious in the field of psychiatry. It is unknown if NIMH takes into consideration the author's h-index during the grant review process. The goal of this study was to determine the correlation between a principal investigator's (PI's) h-index and the NIMH funding.
  
  
  METHODS
  Correlational analysis was conducted on publicly available 2012 NIMH funding data to assess the relationship between NIMH funding and a PI's h-index. A simple linear regression was calculated to predict the h-index based on the amount of funding offered to the PI.
  
  
  RESULTS
  A total of 139 PIs and their corresponding h-index and NIMH funding (direct, indirect, and total cost) were included. A strong correlation was found between h-index and NIMH funding: direct cost (r = 0.632, p < 0.001); indirect cost (r = 0.570, p < 0.001); and total cost (r = 0.639, p < 0.001). Total funding significantly predicted h-index, β = 0.821, t (2.599), p < 0.01, and explained a significant proportion of variance in h-index, R2= 0.410, F (3, 119) = 27.59, p < 0.001.
  
  
  CONCLUSIONS
  A strong relationship was seen between h-index and securing NIMH funding. Thus, h-index stands out as a reliable measure for assessing the impact of scholarly contributions in academic psychiatry and can be used as an adjunct for performance evaluations, appointment, and promotions in academia.
