Objective
To compare publication patterns of doctoral students in a transdisciplinary research-based PhD/MPH degree program (I-TOPP) focused on child obesity prevention to students enrolled in a traditional PhD program within the same academic units.
Description
Publication records of I-TOPP (n=11) and traditional PhD (n=29) students were tracked from matched time of enrollment 2011-2013 to January 2016.
Evaluation
Number of peer-reviewed publications, year of publication, number of authors and departments per publication, and number of citations on Google Scholar were compared between I-TOPP and traditional students. Statistical differences were determined by t-test, p<0.05.
Conclusion and Implications
The I-TOPP students produced 4.5 ± 2.9 publications per student (49 total in 38 journals) compared to 2.1 ± 0.6 publications per student (61 total in 51 journals) produced by the traditional doctoral students, but this difference was not significant. Compared to traditional PhD students, I-TOPP students had more co-authors per publication (7.0 ± 0.4 vs. 5.3 ± 0.4, p =0.003), more departments represented per publication (3.4 ± 0.2 vs. 2.4 ± 0.2, p=0.002) and more organizations on each publication (2.35 ± 0.22 vs. 1.7 ± 0.1, p<0.001). To assess impact, the number of citations in Google Scholar was determined. The number of citations was 4-fold higher (p<0.001) per publication for I-TOPP than traditional PhD students (16.2 ± 3.7 vs. 3.1 ± 0.7). Findings suggest that transdisciplinary training does not negatively impact student publication records. Trandisciplinary trained scholars had publications with more diverse collaborations and higher impact than those from students in traditional doctoral programs.
