This research examines the psychometric properties of an extended version of VASSIP, a gamified assessment to briefly measure dark personality through an immersive situational judgment test (SJT). Methods: A sample of 395 Spanish workers (47.4% female, Mjob experience = 10.4 years) participated in the study, completing questionnaires of the target variables and playing the gamified assessment. Results: The hard-gamified extension of VASSIP has a unidimensional factor structure with 5 items. Validity was supported by direct associations with Honesty-Humility, moral disengagement, task performance, and counterproductive work behaviors (CWBs). Discussion: Therefore, this measure appears to be valuable for briefly assessing dark personality, although its predictive capacity could be optimized. Its situational approach offers a more nuanced understanding of how individuals manifest dark personality in workplace scenarios.2026http://zaguan.unizar.es/record/16872910.3389/fpsyg.2025.1686784http://zaguan.unizar.es/record/168729oai:zaguan.unizar.es:168729info:eu-repo/grantAgreement/ES/DGA/S31-23Rinfo:eu-repo/grantAgreement/ES/MICINN/PID2021-122867NA-I00Frontiers in Psychology 16 (2026), [14 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
