Scholarly Impact of Student Participation in Radiation Oncology Research

Abstract

Toevaluate the rate of non-doctoral student authors publishing in an academic journal over time and to analyze the effects student authors have on the scholarly impact of corresponding authors (CAs) by comparing their respective H-index (Hi). A database was created of authors who published articles in the International Journal of Radiation Oncology, Biology, Physics in 2006, 2010, and 2014 that included CA, degree, and student author designations. Corresponding authors' His were obtained from Scopus (scopus.com). Student authorship rates were compared between the sampled years. The data were divided into 2 groups: CAs publishing with student authors (SA) and those without (nSA). The CAs' median and mean His with standard deviation and a 95% confidence interval were compared between SA and nSA. A total of 1728 published articles were identified with 1477 unique CAs. The percentage of published articles with student authors increased from 44.4% in 2006, to 52.9% in 2010, to 55.9% in 2014 (P=.0003). In overall analysis, mean Hi was higher for SA as compared with nSA (24.3 vs 22.9), although this did not achieve statistical significance (P=.094). Mean Hi (standard deviation) in 2006, 2010, and 2014 was 27.9 (16.6), 23.6 (16.7), and 18.5 (14.6), respectively. Mean Hi was significantly higher for SA compared with nSA in the years 2006 (29.5 vs 26.6, P=.048) and 2010 (24.9 vs 21.9, P=.038) but not in 2014 (18.5 vs 18.4, P=.963). Student authorship rates in the International Journal of Radiation Oncology, Biology, Physics are increasing. The data suggest that student participation in research may benefit both corresponding and student authors. Creating and expanding research programs to integrate research into medical education may enhance students' experience and encourage interest in radiation oncology.
