Faking modeling for forced choice measures in personality assessment based on RES theoretical framework
摘要
Abstract
Although forced-choice(FC)assessments with social desirability matching reduce faking compared to Likert scales,the desirability of items may shift when matched in blocks and vary across contexts.Consequently,faking remains a persistent issue in FC assessments,compromising measurement accuracy and fairness.To address this,we propose a statistical model for detecting and mitigating faking in FC assessments,integrating Böckenholt's(2014)model of RES faking theory with the Thurstone Item Response Theory(TIRT)model(Brown & Maydeu-Olivares,2011).Our approach aims to minimize the adverse effects of faking and enhance the robustness of FC measures. Two simulation studies were conducted to evaluate the proposed RES-TIRT model.Simulation Study 1 examined model performance under varying conditions(sample size,FC scale format,item direction,trait correlation,and dimensionality).Results indicated optimal estimation accuracy when using 3-item blocks,3 dimensions,a correlation of 0 between dimensions,and a mix of positive and negative item descriptions.Simulation Study 2 compared trait estimation accuracy between TIRT and RES-TIRT models under increasing faking prevalence.While the TIRT model performed better in faking-free conditions,its accuracy declined more sharply than the RES-TIRT model as faking increased-particularly for item parameters-demonstrating the RES-TIRT model's superior resistance to faking. An empirical analysis further validated the model's applicability in real-world settings.Comparing honest responses with faked responses(simulating lawyer job applications),we found that applicants strategically inflated traits like openness,agreeableness,and extraversion to meet job requirements.The RES-TIRT model effectively detected these distortions,showing significant discrepancies in these dimensions compared to the TIRT model.Additionally,the RES-TIRT model effectively captured response distortion tendencies,as evidenced by significantly elevated latent trait values θEj under faking conditions compared to honest responses.This indicates that,the faking behavior of the applicants can be successfully captured by the RES-TIRT model.Moreover,the difficulty parameter βEim triggering fake answers can be observed to determine whether a FC block is prone to faking.These empirically derived parameters enable targeted refinements in FC measure development,allowing test constructors to strategically modify or eliminate items with low faking thresholds,thereby enhancing the scale's overall resistance to response biases. In conclusion,both simulation and empirical studies have demonstrated that the RES-TIRT model is a viable alternative to the TIRT model.It can be employed to address the issue of faking in FC scales,particularly in high-stakes situations such as talent selection.关键词
