Are dissertations peer reviewed

However, the extent and nature of dissertation publication remains largely unknown within psychology. The present study investigated the peer-reviewed publication outcomes of psychology dissertation research in the United States. Additionally, we examined publication lag, scientific impact, and variations across subfields. To investigate these questions, we first drew a stratified random cohort sample of psychology Ph.

Next, we conducted comprehensive literature searches for peer-reviewed journal articles derived from these dissertations published 0—7 years thereafter. Published dissertation articles were coded for their bibliographic details, citation rates, and journal impact metrics. Results showed that only one-quarter When dissertations were published, however, they often appeared in influential journals e. Publication typically occurred within 2—3 years after the dissertation year.

Overall, these results indicate that the large majority of Ph. The non-publication of dissertation research appears to be a systemic problem affecting both research and training in psychology. The doctoral dissertation—a defining component of the Doctor of Philosophy Ph. From this definition it follows that most dissertations could, and arguably should, be published in the peer-reviewed scientific literature [ 1 — 2 ]. The nonpublication of dissertation research can also be detrimental to the advancement of scientific knowledge in other ways.

Researchers may unwittingly and unnecessarily duplicate efforts from doctoral research when conducting empirical studies, or draw biased conclusions in meta-analytic and systematic reviews that often deliberately exclude dissertations. Indeed, unpublished dissertations are rarely if ever cited [ 7 — 8 ]. The problem of dissertation non-publication is of critical importance in psychology. Some evidence [ 9 ] suggests that unpublished dissertations can play a key role in alleviating file drawer bias and reproducibility concerns in psychological science [ 10 ].

More broadly, the field of psychology—given its unique strengths, breadth, and diversity—poses a useful case study for examining dissertation nonpublication in the social, behavioral, and health sciences. Like other scientific disciplines, many Ph. However, other new psychologists might not pursue this goal for a variety of reasons.

Those in professional and applied subfields may commit most or all of their working time to non-research activities e. Even those in more research-oriented subfields increasingly take non-research positions e. Negative graduate school experiences, alternative career pursuits, and personal or family matters can all be additional factors that may decrease the likelihood of publication.

Moreover, it is typically a challenging and time-consuming task to revise a lengthy document for submission as one or more journal articles. Still, all individuals holding a Ph. Thus, for scientific, ethical, and training reasons, it is important to understand the frequency and quality of dissertation publication in psychology. There is an abundance of literature relevant to this topic, including student or faculty perspectives e.

However, evidence specifically regarding dissertation publication is remarkably sparse and inconsistent [ 8 , 20 — 24 ]. This literature is limited by non-representative samples, biased response patterns, and disciplinary scopes that are either too narrow or too broad to offer insights that are useful and generalizable for psychological science. For example, in the only psychology-specific study to our knowledge, Porter and Wolfle [ 23 ] mailed surveys to a random sample of individuals who earned their psychology doctorates.

Unfortunately, this study [ 23 ] and others e. A much more recent and rigorous example comes from the field of social work. Using a literature searching methodology and a random sample of doctoral dissertations in social work, Maynard et al [ 22 ] found that However, this estimate likely does not generalize to psychology and its myriad subfields.

Thus, there is a need for more comprehensive, rigorous, and recent data to better understand dissertation publication in psychology. Accordingly, the present study investigated the extent and nature of dissertation publication in psychology, specifically examining the following questions: a How many dissertations in psychology are eventually published in peer-reviewed journals?

Based on the literature and our own observations, we hypothesized that a a majority of dissertations in psychology would go unpublished; b dissertation publication would occur primarily during the first few years after Ph. This resulted in a total population of 6, dissertations, which were then screened and sampled according to pre-defined criteria. The number of dissertations included at each stage in the sampling process is summarized in a PRISMA-style [ 27 ] flow diagram for the overall sample in Fig 1 , and broken down by subfield in Table 1.

Dissertations were excluded if written in a language other than English, for any degree other than Ph. The remaining dissertations were recoded for subfields based on the subject term classification in PQDT, with a few modifications e. This left a remaining sample of 3, relevant dissertations, representing our population.

This figure is approximately in line with the U. Dissertations were excluded in the eligibility stage based on the date of approval in the full text see Fig 1. Rates of exclusion were not significantly different across subfields. Sampling weights for each subfield were calculated as the proportion in the population relevant dissertations divided by proportion in the full sample, after adjusting for the proportions within each subfield that were from excluded for ineligibility.

From this relevant population of 3,, we drew a stratified random sample of 1, dissertations. Ninety 9. This incongruence was partly explained by copyright or graduation dates differing from the dissertation year, and was not significantly different across subfields.

Because this study did not meet the definition of human subjects research, institutional review board approval was not required. Across methodologies, the half-life of knowledge in psychology has been estimated at 7—9 years [ 31 — 33 ]. Accordingly, we selected a prospective search window allowing 0—7 years for dissertations to be published. Because the doctoral dissertations were sampled from the year , follow-up searches were restricted to articles published between and We elected to exclude candidate publications from years prior to for several reasons.

First, most U. Second, even for the minority of programs that might follow less conventional models such as dissertation-by-publication [ 34 ], the lag-time to publication would likely still result in at least one PD appearing in print concurrently with or after the dissertation, and would therefore be captured by our search strategy. On the other end of our search window, candidate publications that appeared in print during or after were also not considered. Post hoc analyses see Results suggested that this 0—7 year timeframe was adequate.

Searches for PDs were conducted in two rounds, utilizing scholarly databases in a manner consistent with the evidence regarding their specificity, sensitivity, and quality. Specifically, searches were conducted first in PsycINFO, which has high specificity for psychological, social, and health sciences [ 35 — 36 ]; and second, in Google Scholar, casting a much broader net but still searching for peer-reviewed scholarly journal articles [ 35 , 37 — 40 ].

The objective of these searches was to locate the PDs or to determine that the dissertation had not been published in the indexed peer-reviewed journals. First, when no PD was found in either scholarly databases, as a final step we conducted Google searches for the dissertation author and title, then reviewed the search results e. Search results were assessed for characteristics of authorship student and chair names , content title, abstract, acknowledgments, methods , and publication type specifically targeting peer-reviewed journal articles by which a PD could be positively identified.

Determination of PD status was made and later validated based on global judgments of these criteria. Identified PDs were then coded for their bibliographic characteristics. Results were excluded if published in a non-English journal, outside of the 0—7 year — window, or in a non-refereed or non-journal outlet e.

Because dissertations can contain multiple studies and be published as multiple articles, searches aimed to identify a single article that was most representative of the dissertation, based on the criteria outlined above and by consensus agreement among coders. All searches were conducted and coding was completed between January and May Although the structure and content of doctoral dissertations varies across institutions, countries, and disciplines, the common unifying factor is that the dissertation represents an original research document produced by the student, approved by faculty, and for which a degree is conferred.

This definition includes all different models of dissertations e. The peer-reviewed status of the journal was included among the variables that were coded twice with discrepancies resolved by consensus. The PQDT subject terms were used as a proxy indicator of the subfield of psychology from which the dissertation was generated. As described above, twelve categories were derived Table 1. Note that Ph. The influence of PDs was estimated using article- and journal-level variables.

At the article level, we used Web of Science to code the number of citations to the PD occurring each year since publication, tracking from up through year Importantly, Web of Science has been found to exhibit the lowest citation counts, but the citations which are included are drawn from a more rigorously controlled and higher quality collection of scholarly publications compared to others like Google Scholar, PubMed, and Scopus [ 35 , 37 — 38 , 40 — 41 ].

Citations were coded and analyzed primarily as the mean number of citations per year in order to account for time since publication. Total citations and citations each year were also calculated. Each of these indices shares different similarities and distinctions from the others and provides different information about how researchers cite articles in a given journal.

As described above, all of the dissertation, literature searching, and outcome data used in the present study were obtained from a variety of online sources available freely or by institutional subscription. Links to these sources can be found in the supplementary materials S1 File. Overall descriptive analyses were conducted to examine the univariate and bivariate characteristics of the data, including the frequency and temporal distribution of PDs in psychology.

Similar descriptive statistics were provided to characterize the nature of and scholarly influence of the PD via article citations and journal impact metrics. Group-based analyses were conducted using chi-square and ANOVAs to assess whether dissertation publication rates and scientific influence differed across subfields of psychology.

Time-to-publication analyses were conducted in three different ways. First, we used weighted Cox regression and Kaplan-Meier survival analyses to model dissertation publication as a time-to-event outcome, both for the overall sample and separately by subfields. Finally, in order to ensure the adequacy of our 0—7 year search window, we fit a distribution to our observed data and projected this trend several years into the future.

Full-sample analyses were conducted using the complex samples option in SPSS Version 24, which yields weighted estimates that are less biased by sample proportions and more generalizable to the population. Distribution model-fitting and projections were estimated in R. For analyses related to dissertation publication outcomes, there were no missing data because all values could be coded based on obtained dissertations.

Data availability for journal- and article-level variables are reported in those results tables. The overall weighted estimate showed that The unweighted estimate was similar Thus, weighted estimates are used in all subsequent results. As shown in Table 2 , greater proportions of PDs were found in neuroscience All other subfields fell between The overall time-to-publication results are presented in Table 3 and the left panel of Fig 2.

As shown, over half These results generally mirrored the same pattern found for overall binary publication outcomes across subfields. Subfield estimates right panel are derived from the unweighted Kaplan-Meier regression model. See Fig 2 , left panel, for a visual presentation of these results. Lastly, as a methodological check, we modeled our time-to-publication data and projected this trend into the future to estimate what percentage of PDs we might have missed by stopping after 7 years.

More specifically, these models used the weighted estimates of how many dissertations were published each year as the outcome and time years 0 to 7 as the predictor. A Poisson model containing quadratic and linear effects for time fit the data best. When projected into the future, this model estimated that an additional 7 dissertations would be published at 8—10 years post-dissertation 4, 2, and 1 PDs, respectively.

From 11 years onward, estimates asymptotically approached and rounded down to zero, even cumulatively. Thus, our sampling frame appears to have captured virtually all In other words, had the study been implemented for as long as necessary to capture all PDs, the data suggest that our primary result, the estimated percentage of dissertations published, would increase only modestly from As shown in Table 4 , PDs were cited an average of 3.

There were significant variations by subfield in terms of both total and per-year citations. Estimates are calculated from available years from the publication year inclusive through This sampling range naturally truncates the number of follow-up years available for dissertations published in later years e.

The PDs in our sample appeared in different peer-reviewed outlets, including top-tier journals in general e. Notably, several PDs appeared in journals predominately representing professions or disciplines outside psychology e. The most common journal titles were all in relatively specialized areas of psychology e. As shown in Table 5 , PDs appeared in journals of moderate-to-high influence according to all five metrics used.

The primary finding of this study was that only about one in four psychology Ph. Typically this occurred within 2—3 years after completing the dissertation. Despite variations across subfields, dissertation publication appears to be the exception not the rule. When dissertations were published, however, they were often highly cited and appeared in influential journals.

The relatively high impact of published dissertations may reflect a gatekeeping effect, whereby only the highest quality or most significant contributions get published; or a refining effect, whereby the dissertation development and committee review process helps strengthen the contribution [ 1 , 46 ], increasing the likelihood and impact of publication.

In other words, the dissertation process may add some value to doctoral research, and some doctoral research appears to add value to psychological science. A larger and more important question is why the vast majority of psychology dissertation research does not contribute to the peer-reviewed literature. Our estimated rate of dissertation publication in psychology To our knowledge, the present study is the first to offer a reliable estimate of publication rates specific to the dissertation and specific to psychology.

Further, the present study advances the literature by demonstrating the impact that these published dissertations have on the scientific literature. Although it was only minority of cases, published dissertations in psychology were disseminated in moderate- to high-impact journals across a wide spectrum of disciplines and specialty interests. Whereas published dissertation articles were cited several times per year, anecdotally we saw very few citations to the actual dissertation documents in PQDT.

These observations are consistent with evidence showing that the impact of dissertations themselves has declined markedly [ 7 — 8 ] in recent decades. In contrast, peer-reviewed journal articles are much more likely to be read, cited, and included in systematic and meta-analytic reviews.

Subfield differences were broadly consistent with hypotheses. Given this relatively low baseline rate of productivity during graduate school for this population, the average likelihood of post-graduation publication seems low. On the other hand, individuals in more research-oriented subfields are often training specifically for an academic position which incentivizes publication.

Further, lab-based dissertations often include multiple experiments, which may create more publishable units this also may explain the relatively higher rate of publication in behavioral psychology. The time from dissertation completion to publication appears to be a critical consideration.

Thus, if students wish to publish their dissertation, it is recommended that they proactively develop a plan for adapting the full document into a manuscript or multiple manuscripts for publication [ 1 ]. As one example of this, we are aware of some universities that have begun requiring that approved dissertations be accompanied by a form that outlines an agreed-upon plan for publication and authorship. The present findings raise questions about the reasons for nonpublication.

Possible explanations include the burden of revising and submitting a lengthy document, or limited career incentives for pursuing publications in non-academic careers. Thus, unpublished dissertations might not pass the bar of peer review. The present results only illustrate how many dissertations were actually published, and cannot speak to how many students attempted to publish their dissertations, or how many dissertations might have been publishable quality.

Similarly, these results do not provide direct evidence of the mechanisms underlying publication vs. Such questionable research practices may provide one explanation for how dissertations selectively get published, but this is clearly not an appropriate solution. Whatever the underlying explanations may be, the widespread non-publication of dissertation research is a problem in psychology.

To the extent that this non-publication continues, it exacerbates the file drawer problem [ 5 — 6 , 9 ], biases systematic reviews and meta-analyses, and contributes to the replication problem in psychology [ 10 ].

It also amounts to inefficient use of time and resources, raising ethical questions about violating agreements with participants and funding agencies, and about the consequences of not disseminating research findings [ 2 , 4 ].

The present study was designed so that results could be generalized to the population of dissertations produced in U. However, some limitations should be noted. First, our stratified random sample was drawn from an archival data source PQDT , which is an approximation of the population of dissertations in psychology although a very comprehensive one and a proxy of the boundaries delineating subfields in psychology. Our outcome variables were likewise drawn from various databases e.

As noted in the Methods section, these databases were selected as the most comprehensive and appropriate sources available for the purposes for which they were used, and their strengths and weaknesses were considered in developing the study protocol. The changing landscape of doctoral training in psychology e. Of note, these results may not generalize broadly to other countries e. Anonymity is maintained at both ends.

Kennedy, New York, Purdue and many others. Writing Dissertation is a challenging task and many times the outcome is often not as anticipated. At the PhD level, the review committee or evaluators expect to receive reports written with absolute accuracy. The research results have to be valid and reliable; otherwise many questions are raised about the authenticity of the work, rigor in research, scholarly writing and formatting. There must be no trace of plagiarism, as this is considered to be a grave offense.

The language has to be academic and vocabulary must be rich. Ensuring that all these conditions are met is not easy. The university committee will not accept your dissertation till the time it is perfect. You may have to revise and make corrections over and over again with limited feedback provided every time. Many candidates tend to lose patience and feel overwhelmed with repeated changes required in the work. With a peer review of your dissertation, you eliminate the risk, repeated efforts and get the most of the feedback of your work in one go.

This will not just guarantee a high score, but also a positive impression on the committee members, which can prove to be crucial for furthering your academic career.

A college dissertation would be considered a scholarly work, but a dissertation is different from an article in ways that may be important to you. A dissertation is usually the length of a book, perhaps pages or more. If it is not already available to you, obtaining a dissertation may be more difficult than obtaining an article. There are far more articles written than dissertations. Your particular assignment may specifically require scholarly articles rather than scholarly books or book-length writings, perhaps for the reasons above, perhaps for other reasons.

Toggle menu visibility. Ask Another Question. Answered By: Jane Swiszcz. Last Updated: Jul 23, Views: Scholarly journals are journals which are well respected for the information and research they provide on a particular subject. They are written by experts in a particular field or discipline and their purpose is to advance the ongoing body of work within their discipline.

These articles might present original research data and findings, or take a position on a key question within the field. They can be difficult to read, because their intended audience is other experts and academics, but they are the capstone when it comes to authoritative information. Scholarly journals are oftentimes peer reviewed or refereed. The actual evaluations are similar to editing notes, where the author receives detailed and constructive feedback from the peer experts.

However, these reviews are not made available publicly. For an example peer review of a fictitious article, see the Sample Peer-Review of a Fictitious Manuscript link below. Please keep in mind that not all scholarly journals go through the peer-review process. However, it is safe to assume that a peer-reviewed journal is also scholarly. The vast majority of scholarly articles are peer reviewed. However, because there are many different types of peer-review, be sure to evaluate the resource itself to determine if it is suitable for your research needs.

For example, law reviews may indicate that they are peer-reviewed, but their "peers" are other students. If you need help determining whether a scholarly journal is peer reviewed or refereed we recommend using the Ulrichsweb database.
