This study aimed to develop the first psychometric instrument for assessing mental illness malingering in the workplace. Pearson's bivariate correlations were calculated between the dimensions of the PES-L and the SIMS and SCL-90-R tests. Sensitivity, specificity, and potential cutoff scores were determined using independent samples t-test and Cohen's d to determine effect size. ROC curve analysis was conducted to differentiate between two groups based on the total scale score. Results revealed an area under the curve of 0.81 (p = 0.000, 95 % CI: 0.73 - 0.89). A cutoff score of 14 correctly classified 72.16 % of potential simulator individuals. The PES-L has shown potential as a psychometric instrument for detecting malingering in cases of mental health-related work absences.
