The Imposter Phenomenon (IP) is gaining increasing attention in academia, not only as an overall attractive research topic but also as a concern that especially affects members of minority groups. Nevertheless, there is little evidence for the occurrence and socio-structural correlates of the IP. Against the backdrop of a pressing need to contextualize the IP, this paper provides (1) an overview of the existing empirical evidence on the IP from a perspective that incorporates the role of social contexts, (2) highlights shortcomings in both existing theoretical approaches and methodological tools, (3) introduces the Impostor Phenomenon Short Scale (IPSS-3) as a novel, time-efficient and universally applicable IP measure, and (4) underscores that the IP, in fact, does not occur in a social vacuum but is closely intertwined with socio-structural characteristics. To this end, the paper draws on three distinct data sets gathered among German adolescents and adults for the development of the IPSS-3 (Study 1: n = 271), its validation (Study 2: n = 427), and to assess the IP’s socio-structural correlates (Study 3: n = 865). The findings demonstrate that the IPSS-3 represents the first time-efficient and universally applicable instrument suitable for capturing the IP in large-scale and longitudinal research designs, e.g., initiated in adolescence. Thus, the IPSS-3 can address key open questions related to age effects, the role of transitions in the life course, and systematic variations in IP intensity among different social groups.

Unequal political participation increasingly challenges democracies. The turnout gap is particularly large among younger voters, with severe implications for future developments of democratic representation, legitimacy, and quality. This article focuses on the role of political efficacy beliefs in explaining unequal turnout among newly enfranchised citizens. We argue that internal political efficacy beliefs are particularly important for turnout among the newly enfranchised from lower-class backgrounds, as they lack alternative mobilizing factors such as politically aware and active parents, political knowledge, and mobilizing networks. Furthermore, we argue that once these voters successfully turn out in their first election, they are as likely as those from higher-class backgrounds to turn out in their second election. We empirically test these arguments using original longitudinal data on newly enfranchised citizens from three German federal states (Bundesländer). Overall, our results support the argument: Political efficacy beliefs are a stronger predictor of first turnout among young adults from disadvantaged backgrounds compared to those from more advantaged backgrounds, and those who do turn out are as likely as those with higher-class backgrounds to turn out in their second election. This highlights the relevance of political efficacy beliefs in the (re)production of persisting political inequality.

Despite decades of research, major gaps remain in understanding the Impostor Phenomenon (IP), particularly regarding its social stratification and structural implications. While traditionally viewed through a merely psychological lens, the IP is increasingly recognized as being shaped by broader contexts such as structural inequalities and discrimination. This study aims to provide a concise, cross-nationally validated instrument for measuring IP feelings in large-scale surveys. We validate the Impostor Phenomenon Short Scale (IPSS-3), a brief self-report instrument suitable for surveys with limited assessment time. Using data from 424 German- and 477 Hebrew-speaking adolescents and young adults (aged 16–28), the factor structure, internal consistency, and construct validity of the IPSS-3 are examined via its correlations with the external locus of control and self-esteem. These analyses confirm high reliability and consistent validity across both samples. The IPSS-3 enables researchers to explore the intersection of IP-related self-doubt and perceived lack of belonging with opportunities for social participation, workplace belonging, career development, and social mobility. By providing a reliable and efficient measure of the IP, this study promotes interdisciplinary research on the IP and enhances a nuanced understanding of how subjective self-perceptions intersect with structural opportunities and social stratification.

Background and aim: Patient satisfaction is a critical indicator of healthcare quality, shaping treatment adherence, continuity of care, and the allocation of resources. The Short Assessment of Patient Satisfaction (SAPS) is a brief, reliable tool that is widely used internationally, but no validated Arabic version currently exists. Therefore, this study aimed to translate, culturally adapt, and validate the SAPS into Arabic for use in primary care clinics. Methods: We conducted a cross-sectional validation study at general practice clinics of a tertiary academic hospital in Riyadh, Saudi Arabia (June–August 2025). Consecutive Arabic-speaking patients aged 18–80 were recruited post-visit and completed a self-administered electronic survey including the Arabic Short Assessment of Patient Satisfaction (Ar-SAPS), PSQ-18, and PDRQ-9, as well as demographic and visit variables. Psychometric testing included internal consistency, test–retest reliability, construct validity, and factor analysis. Results: A total of 273 participants enrolled in our study. The Ar-SAPS demonstrated good reliability (Cronbach’s α = 0.789; McDonald’s ω = 0.882) and moderate test–retest stability (ICC = 0.634, p < 0.0001). Factor analysis supported a primarily unidimensional structure, with the first factor explaining 60.2% of variance. Most inter-item correlations were moderate to strong, except for item 6. Convergent validity was supported by significant correlations with the Arabic PDRQ-9 (r = 0.623, p < 0.001, CI [0.532, 0.713]) and PSQ-18 (r = 0.662, p < 0.001, CI [0.531, 0.793]), confirming consistency with established measures of patient satisfaction. Furthermore, it demonstrated excellent discriminative ability, with areas under the curve of 0.965 for overall satisfaction and 0.955 for willingness to recommend. Conclusion: The Ar-SAPS is valid and reliable for use to assess patient satisfaction.

Corrigendum on: Jansen, M. P. (2024). Impostor Phenomenon Short Scale (IPSS-3). A Novel Measure to Capture Impostor Feelings in Large-scale and Longitudinal Surveys. Front. Psychol. doi: https://doi.org/10.3389/fpsyg.2024.1358279 Missing citation Leonhardt et al., 2025 was not properly cited in the article. The IPSS-3 scale is based on intensive prior work that had not been published at the time of submission. This is why the author wishes to underscore that the IPSS-3 builds directly upon the work by Leonhardt et al., 2025. The citation is now available and should be included in the section "4 IPSS-3: a universally applicable IP instrument", Paragraph 1 and read as: "A preliminary short version of the original ISCQ called ISCQ-5 (ISF-K; Leonhardt et al., 2025) was chosen as the base instrument for developing the IPSS-3 since it is comparably short and recently developed. Furthermore, it is designed based on a scale with a unidimensional factor structure and shows a highly positive correlation with another established IP scale (CIPS)."
