Development and assessment of a sustainable PhD internship program supporting diverse biomedical career outcomes
Figures

Benefits of internship for different stakeholders (quantitative evidence).
(a–h) Benefits to interns documented through post surveys. (i–m) Benefits to interns documented through pre- and post-surveys. (n–u) Benefits to internship hosts documented through post surveys. (v–x) Benefits to research advisors documented through post surveys. Mean values for the benefits to the interns documented through pre- and post- (i–m) were tested for significance using an independent samples t-test. Asterisk(s) indicate(s) differences were statistically significant (*p<0.05; **p<0.01; ***p<.001).

Benefits of internship for different stakeholders (qualitative evidence).
Stakeholder interviews were moderated by an external evaluation team, with participants’ identity remaining confidential. Interviews were transcribed and imported into Atlas.ti, with the evaluator developing codes for key themes. Representative quotes supporting each major theme that emerged are presented in the figure.

Sustainability and lessons learned (quantitative evidence).
(a–h) Internship host ratings of various internship components that are proxies for sustainability. (i–t) Research advisor ratings of various internship components that are proxies for sustainability. (u) A crosstab of research advisors’ ratings of frequency and sufficiency of communicating with project leadership.
