However, the type of GRA under investigation should be considered. This study focuses on game-based assessments, which closely resemble leisure-oriented videogames. We specifically examined a serious game that assesses personality traits (assertiveness, sociability, tolerance, and rules). We analyzed its predictive validity, applicant reactions, and the impact of personal and job-related factors on scores. The study included 182 participants who played the GRA and completed a Big Five questionnaire. Findings revealed that the game predicts adaptive performance, offering incremental value over the Big Five (ΔR2 = .107). Additionally, candidates reacted more positively to the GRA in terms of comfort and fit, although the effect size was small (d = -0.1757 and -0.3119, respectively). Relating to personal and job-related characteristics, only job experience significantly affected the assertiveness score, albeit with a small effect size (d = -0.3870).2023http://zaguan.unizar.es/record/13174010.5093/jwop2023a18http://zaguan.unizar.es/record/131740oai:zaguan.unizar.es:131740info:eu-repo/grantAgreement/ES/DGA/S31-20Dinfo:eu-repo/grantAgreement/ES/MICINN/PID2021-122867NA-I00Revista de psicología del trabajo y de las organizaciones 39, 3 (2023), 169-178by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
