Imposter phenomenon (IP) is an evolving, multidimensional construct defined as self-perceived intellectual phoniness and professional ineptitude frequently experienced by individuals working in high-performance or competitive environments. IP consequences include psychological distress, role underoptimization, and career dissatisfaction. As high-achieving advanced practice nurses in a profession often evaluated by peers, certified registered nurse anesthetists (CRNAs) are at risk for IP. Identifying impostorism early in the CRNA\'s career and adopting healthy management strategies can optimize the nurse anesthesiologist\'s healthcare role, lead to a more fulfilling career, and support personal wellness.

Impostorism and knowledge-hiding behaviors negatively impact employees and organizational performance. This study examines the association between impostor leaders and knowledge hiding (evasive hiding, playing dumb, and rationalized hiding). Attachment avoidance is discussed as a mediator between impostor leaders and knowledge-hiding. For quantitative analyses, this study collected the data from 429 individuals with two time lags by sharing the survey instrument link on different organizations\' randomly selected official media pages. After obtaining approval from the administrators of these pages, leaders and subordinates from these organizations were asked to participate in the study. The partial least squares structural equation modeling method is employed with Smartpls-4 software for data analyses. The findings indicate that impostor leaders promote knowledge hiding in subordinates. However, impostor leaders highly promote rationalized hiding behavior in subordinates. Attachment avoidance mediates the relationship between the impostor leader and knowledge-hiding behaviors. However, the highest mediation relationship exists between an impostor leader and playing dumb behavior in subordinates. This study strengthens the generalizability of the social exchange theory. The implications mentioned in this study are beneficial in understanding and dealing with the Impostorism and knowledge-hiding phenomena.

Investigate the prevalence and contextualize the relationship of impostor phenomenon (IP) and ambiguity tolerance (AT) in practicing physical therapists (PTs).
Online survey including demographic questions, Clance Impostor Phenomenon Scale (CIPS), and Tolerance of Ambiguity Scale (TAS).  Descriptive analyses assessed (N = 422) demographic data, CIPS, and TAS scores. Chi-square tests determined distribution across demographic variables.  Kruskal-Wallis tests assessed differences between CIPS and TAS.  Age was a proxy for career stage in Pearson product-moment correlations to assess relationships between CIPS and TAS.
In practicing PTs (M age = 42.12, SD = 12.34), moderate (48.6%; n = 205) to frequent (26.8%; n = 113) IP feelings were prevalent, but only 31.5% (n = 133) were true impostors.  Significant differences exist in clinical experience for CIPS, H(7, n = 422) = 67.82, p <.001 and TAS, H(7, n = 422) = 21.79, p= .003. Most PTs tolerate ambiguity (M = 54.93, SD = 8.19).  A moderate negative correlation between age and CIPS, r = -.36, p <.001 and a small negative correlation between age and TAS, r=-.19, p <.001 exists. Age accounts for 13% of the variance per IP and 3.6% variance per TAS score.  A small positive relationship exists between CIPS and TAS, r = .10, p <.05.
Practicing PTs experience moderate to frequent IP and are ambiguity tolerant.  Clinical experience is inversely related to IP and AT.  Almost half of early-career PTs feel like impostors, which can lead to decreased job satisfaction, burnout, psychological distress, feelings of self-doubt, and depression.

OBJECTIVE: To identify the prevalence and severity of impostor phenomenon and burnout in newly licensed registered nurses, map the current literature on impostor phenomenon in nursing, and identify related factors affecting the new nurse\'s transition to practice.
BACKGROUND: Impostor phenomenon is an internalised intellectual phoniness resulting in persistent self-doubt despite prior success. It can evoke feelings of emotional exhaustion associated with burnout, negatively affecting employee retention. Due to changes in nursing education resulting from COVID-19, self-doubt and uncertainty among new nurses are expected to be heightened, leading to burnout which adversely effects nurse well-being, patient care and retention.
METHODS: The scoping review follows the methodological framework developed by Arksey and O\'Malley (2005) and the Reporting Checklist for Scoping Reviews (PRISMA-ScR) guidelines.
METHODS: The literature search was conducted utilising PubMed, CINAHL and PsycINFO. Inclusion criteria were studies published between 2011 and 2021, written in English, peer-reviewed, and focused on newly licensed registered nurses. Eighteen articles were reviewed.
RESULTS: Studies on impostor phenomenon in nursing are limited to nursing students and clinical nurse specialists. Prevalence of impostor feelings in these populations range from 36% to 75%, and 12.3% to 46% of new nurses report burnout. Impostor feelings arise from role ambiguity, lack of self-compassion, transitions, and minimal clinical experience. Burnout was associated with stress, feeling unprepared, inadequate socialisation, and lack of self-compassion. Overlap in these factors could increase impostor feelings and burnout in new nurses.
CONCLUSIONS: Effects of impostor phenomenon and burnout can negatively impact the well-being of the new nurse. Currently, no studies simultaneously examine impostor phenomenon and burnout in new nurses. Further research on the relationship between these phenomena should be conducted.
CONCLUSIONS: Understanding the impact of impostor phenomenon and burnout on new nurses could help mitigate challenges they face transitioning into practice.

Physician burnout is an issue that has come to the forefront in the past decade. While many factors contribute to burnout the impact of impostorism and self-doubt has largely been ignored. We investigated the relationship of anxiety and impostorism to burnout in postgraduate medical learners.
Postgraduate learners in four diverse training programs: Family Medicine (FM), Paediatric Medicine (PM), Anesthesiology (AN), and General Surgery (GS) were surveyed to identify the incidence of impostorism (IP), anxiety, and burnout. IP, anxiety, and burnout were evaluated using the Clance Impostor Phenomenon Scale (CIPS), Maslach Burnout Inventory-Human Services Survey (MBI-HSS), and the General Anxiety Disorder-7 (GAD-7) questionnaires, respectively. Burnout was defined as meeting burnout criteria on all three domains. Relationships between IP, anxiety, and burnout were explored.
Two hundred and sixty-nine residents responded to the survey (response rate 18.8%). Respondents were distributed evenly between specialties (FM = 24.9%, PM = 33.1%, AN = 20.4%, GS = 21.6%). IP was identified in 62.7% of all participants. The average score on the CIPS was 66.4 (SD = 14.4), corresponding to \'frequent feelings of impostorism.\' Female learners were at higher risk for IP (RR = 1.27, 95% CI: 1.03-1.57). Burnout, as defined by meeting burnout criteria on all three subscales, was detected in 23.3% of respondents. Significant differences were seen in burnout between specialties (p = 0.02). GS residents were more likely to experience burnout (31.7%) than PM and AN residents (26.7 and 10.0%, respectively, p = 0.02). IP was an independent risk factor for both anxiety (RR = 3.64, 95% CI:1.96-6.76) and burnout (RR = 1.82, 95% CI: 1.07-3.08).
Impostorism is commonly experienced by resident learners independent of specialty and contributes to learner anxiety and burnout. Supervisors and Program Directors must be aware of the prevalence of IP and the impact on burnout. Initiatives to mitigate IP may improve resident learner wellness and decrease burnout in postgraduate learners.

Aging veterans often suffer from increased vulnerability, manifested among other things in old subjective age and poor perceived health. Though research has documented the contribution of trauma related variables to these negative appraisals, their associations with impostorism (i.e., the subjective experience that one is less adequate than others perceive) remain unexamined.
Filling this gap, this study explored the relations between impostorism and subjective age and perceived health among aging combat veterans.
The study was conducted among 146 Israeli veterans of the 1973 Yom Kippur War. Participants were assessed for combat exposure, Posttraumatic Stress Disorder (PTSD) symptoms, and health-related behaviors during middle adulthood (1991; T1), and for subjective age, perceived health, impostorism, PTSD symptoms, and depressive symptoms during old age (2018; T2).
The veterans\' impostorism was associated with relatively old subjective age and poor perceived health, above and beyond the effects of age, health-related behaviors, combat exposure, depressive symptoms, and PTSD symptoms.
The current results suggest that impostorism may contribute to veterans\' stress and negatively affect their evaluations regarding age and health.

The impostor phenomenon is a pervasive psychological experience of perceived intellectual and professional fraudulence. It is not a diagnosable condition yet observed in clinical and normal populations. Increasingly, impostorism research has expanded beyond clinical and into applied settings. However, to date, a systematic review examining the methodological quality of impostorism measures used to conduct such research has yet to be carried out. This systematic review examines trait impostor phenomenon measures and evaluates their psychometric properties against a quality assessment framework. Systematic searches were carried out on six electronic databases, seeking original empirical studies examining the conceptualization, development, or validation of self-report impostor phenomenon scales. A subsequent review of reference lists also included two full-text dissertations. Predetermined inclusion and exclusion criteria were specified to select the final 18 studies in the review sample. Of the studies included, four measures of the impostor phenomenon were identified and their psychometric properties assessed against the quality appraisal tool-Clance Impostor Phenomenon Scale, Harvey Impostor Scale, Perceived Fraudulence Scale, and Leary Impostor Scale. The findings often highlighted that studies did not necessarily report poor psychometric properties; rather an absence of data and stringent assessment criteria resulted in lower methodological ratings. Recommendations for future research are made to address the conceptual clarification of the construct\'s dimensionality, to improve future study quality and to enable better discrimination between measures.

Objectives: The aging process may be affected by negative life events as well as social factors. Though psychological aspects of the aging process in veterans have been the focus of considerable research, decorated veterans have been scarcely investigated in this domain. The current study sought to assess psychiatric distress (PD) levels among aging decorated and non-decorated veterans\' (DVs and n-DVs, respectively) and examine its association with the maladaptive perception that others will identify a high-achieving person as an impostor (i.e. impostorism) and perceived social isolation (i.e. loneliness).Methods: Two groups of Israeli veterans of the 1973 Yom Kippur War, DVs (n = 75) and n-DVs (n = 73), were assessed for PD and combat exposure in middle adulthood (1991; T1); in later life (2018; T2) they were assessed for negative life events, impostorism, loneliness and PD.Results: Impostorism, loneliness and PD were all inter-correlated. DVs evinced less PD at T1 and T2 than n-DVs but similar levels of impostorism and loneliness at T2. Nevertheless, negative life events, impostorism and loneliness explained PD at T2, with loneliness being more significant, especially among the n-DVs. Combat exposure did not explain variances in late-life PD.Conclusion: Aging DVs seem to be less vulnerable to late-life PD than n-DVs, and impostorism and loneliness may be important factors in this respect. Being the first study to investigate aging DVs\' mental health and impostorism among aging veterans, the findings further underscore the clinical imperative of psychosocial factors in understanding aging veterans\' mental health.

OBJECTIVE: Impostor phenomenon (IP) characterizes feelings of self-doubt coupled with feelings that achievements were based on luck and a fear of being discovered as an intellectual fraud. Recently, studies have focused on IP in medical trainees and its association with burnout; however, this research has not yet been conducted on surgeons. This study addresses that gap by investigating the prevalence of IP and burnout in general surgeons and surgery residents.
METHODS: Participants completed two unlinked, blinded surveys. The first survey included demographics and scholarly activity, while the second included the Clance Impostor Phenomenon Scale (CIPS) and a validated, single-item burnout score.
METHODS: Hennepin County Medical Center and University of Minnesota, Minneapolis, MN.
METHODS: General surgeons and general surgery residents at two teaching hospitals, one community-based (N = 46) and one university-based (N = 42).
RESULTS: The majority of both surgeons and residents were male, Caucasian, and married. Residents scored significantly higher compared to faculty in nearly half of CIPS questions. The overall CIPS score was significantly higher in trainees as well (61 vs 51, p = 0.017). Burnout did not differ significantly between trainees (30%) and faculty (41%) (p = 0.545). We found no significant differences in gender or years of practice in those with clinical IP (CIPS >62), and logistic regression analysis showed burnout as the only significant association for clinical IP symptoms (OR 3.95, p = 0.017).
CONCLUSIONS: Contrary to studies in other medical fields, female general surgery faculty and trainees were no more likely than males to display characteristics of IP. Residents did; however, score higher than faculty on overall CIPS score. While we cannot determine how burnout and IP directly impact each other, our study shows that both faculty and trainees experiencing burnout are more likely to report symptoms of IP.
