Dissemination of PhD Dissertation Research by Dissertation Format: A Retrospective Cohort Study

Abstract

Purpose The study purpose was to compare dissemination of PhD dissertation research by dissertation format: traditional (five‐chapter document providing a complete and systematic account of the PhD research) versus an alternate (substudy [document containing three smaller studies but not written as stand‐alone manuscripts] or publication [document containing three or more related manuscripts intended for submission or published in a peer‐reviewed journal]) format. Design A retrospective study of all PhD dissertations (1999–2019) from one research intensive school of nursing. Methods Following identification of graduates via the school's PhD database, we searched ProQuest and PubMed databases for the dissertation and first authored peer‐reviewed publications of each graduate to determine dissertation format, study design, timing and number of dissertation research publications, and inclusion of dissertation sponsor in authorship. Data were analyzed using descriptive statistics and Wilcoxon rank sum tests. Findings Of 113 graduates, 80 (70.8%) employed a traditional format, with the remaining graduates structuring dissertations using an alternate (substudy [n = 12], publication [n = 21]) format. Of those using the traditional format, 33 graduates (41.3%) never published dissertation research findings in a peer‐reviewed journal. For those who published their dissertation research in a peer‐reviewed journal, time to first publication was 1.4 ± 2.1 years (median 1.6 years) following degree conferral. In contrast, all graduates who utilized alternate formats published one or more components of their dissertation research with shorter time to first published manuscript (‐0.6 ± 1.1 years; median ‐0.5 years; p < .001). Number of peer‐reviewed publications was higher for those who utilized an alternate format compared to the traditional format (2.9 ± 1.5 [median 3.0] vs. 1.8 ± 1.1 [median 1.0], p = .001). Acknowledgment of the sponsor's contribution via publication authorship was higher for those using an alternate format compared to the traditional format (100% vs. 70.2%). Conclusions Number and timeliness of peer‐reviewed publications stemming from dissertation research was higher for PhD graduates who utilized an alternate dissertation format. Alternate dissertation formats should be encouraged by PhD programs as one means to improve dissemination of PhD nursing research. Clinical Relevance Dissemination of PhD research through peer‐reviewed publications promotes the continued development of nursing science to inform nursing practice and advances the career trajectory of PhD graduates.

"Addressing Barriers to Post-Graduate Research Training in Low Resource Settings: An Innovative Approach in an Institution of Higher Learning in Kenya"

“…Medical specialist are expected to lead multi-professional healthcare teams, be experts in their elds, and be able to assimilate pertinent medical knowledge and critically assess emerging ndings in the literature as such, they must possess a level of familiarity with the medical literature that can only be attained by conducting research and publishing papers themselves, (28). The dissemination of research through peer-reviewed publications is critical for the profession and the professional development of the upcoming medical scientist (29).…”

Writing phd thesis in English: Importance, challenges, and thesis originality

“…It is a well-known fact that unpublished findings from a PhD theses are a lost opportunity for both the candidate and the scientific community because research findings reported in thesis are less likely to be cited in academic journals, especially if the thesis is not written in English (4). This is an important reason why both candidates and supervisors would like to publish the results before the PhD thesis is submitted and defended.…”

Thinking bigger: The importance of an ambitious doctoral research project

“…This book focuses on doctorates of this format, which is the most common in the social sciences. However, there is no evidence suggesting that the quality of research undertaken or the training given to new researchers needs to vary because of the precise format of their doctoral studies (Evans et al, 2018;Smaldone et al, 2019). The key to all doctorates, this highest qualification, is generally thought to be the quality of research they report.…”
