The impostor phenomenon among doctoral students: a scoping review
Open accessAbstract
Emerging evidence suggests that the Impostor Phenomenon (IP) among doctoral students is a serious problem worldwide academic. Although previous studies demonstrate that IP can endanger doctoral students’ academic advancement and psychological well-being, limited studies systematically and comprehensively explore the IP among those population. Thus, the fundamental goal of this study is to conduct a scoping review of IP among doctoral students so as to clarify the reality of their situation. Systematic searches were conducted using 5 databases: Springer, Google Scholar, Web of Science, PubMed, and JSTOR for empirical studies published from 1978 to 2023. Two reviewers independently carried out the literature search, study selection, data extraction and assessment of study; disagreements were resolved by a third reviewer. Thirty empirical studies covering four specific domains were include in current research, including the characteristics of IP among doctoral students, factors contributing to IP among doctoral students, correlation of IP with doctoral students’ mental illness, and measurement of IP. The findings of this study may provide insight to improving the comprehension of IP among doctoral students and establishing the groundwork for future research in this field.

Written from the paper’s full text.
TL;DR
This scoping review maps 30 empirical studies on the impostor phenomenon (IP) among doctoral students across characteristics, contributing factors, mental-health correlations, and measurement. It finds IP is prevalent and linked to anxiety, depression, burnout, and academic difficulties, while noting that CIPS is widely used and the DIS scale is tailored to doctoral students.
Key findings
- Across 30 included empirical studies, IP among doctoral students was organized into four domains: characteristics of IP, factors contributing to IP, correlation of IP with mental illness, and measurement of IP.
- Publication trends: two-thirds of the 30 papers were published between 2010 and 2023; over half were conducted in the United States; disciplines included medicine (6), psychology (4), STEM (3), clinical psychology (2), and others (7). The Clance Impostor Phenomenon Scale (CIPS) was used in 10 studies; study types were 24 surveys, 4 qualitative studies, and 2 narrative reviews.
- Reported prevalence in reviewed studies included 50.6% of PhD students at ECOOM Ghent University believing they suffer from IP, 56.15% of 130 Romanian psychology graduate students experiencing high/intense IP, and 73% of 1,450 Canadian medical students having moderate or severe IP symptoms. Nori and Vanttaja surveyed 1,694 Finnish doctoral students and developed the 10-item Doctoral Impostor Syndrome (DIS) scale.
- IP was associated with anxiety, fear, depression, burnout, procrastination, and perfectionism; in 169 Russian college students, IP fully mediated the link between perfectionism and anxiety and partially mediated perfectionism and depression, and in Maftei et al. (2021) IP mediated the relationship between procrastination and anxiety. CIPS was described as the “gold standard” for measuring IP, while DIS was considered more appropriate for doctoral candidates specifically.
Methods
- Scoping review following Arksey and O’Malley’s five-step framework and reported according to PRISMA-ScR; two reviewers independently conducted the literature search, study selection, data extraction, and assessment, with disagreements resolved by a third reviewer.
- Searched Springer, Google Scholar, Web of Science, PubMed, and JSTOR for English-language empirical studies published from 1978 to 2023; inclusion required focus on IP among doctoral students, English language, full-text access, and peer-reviewed journal study.
- The initial search yielded 578 articles; after title/abstract review, 161 remained; 21 full-text articles addressed doctoral impostor phenomenon, and 9 additional articles were found from reference lists, yielding 30 included studies. Data were charted into general overview, target group, study design, and results.
Limitations
- The paper states that it focused exclusively on English-language publications, potentially overlooking research in Spanish, French, and Russian; that it did not assess the quality of the literature, which may reduce the accuracy of conclusions; and that conclusions may not be verified due to lack of actual inquiry.
- Evident from the text: the included studies are heterogeneous in design, sample, discipline, and measure (e.g., surveys, qualitative studies, narrative reviews; CIPS, DIS, PFS, BSI), so findings are summarized descriptively rather than pooled, and no meta-analysis or formal quality appraisal is reported.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
