Faking resistance of a quasi-ipsative RIASEC occupational interest measure

Abstract

Quasi-ipsative (QI) forced-choice response formats are often recommended over single-stimulus (SS) as a method to reduce applicant faking. Across three studies we developed and tested a QI version of the RIASEC occupational interests scale. The first study established acceptable reliability and validity of the QI version. The second and third studies tested the efficacy of the QI version for faking prevention in simulated job applicant scenarios. The results revealed that although the QI and SS formats were similarly fakable for the primary targeted interest, faking was limited for the secondary target on the QI version. Future research should identify the specific contexts in which QI prevents faking on various individual differences measures to allow for accurate recommendations in applied settings.
