Abstract


This study aimed to identify items on psychological scale vulnerable to faking responses when it is applied to the employee selection process.

The first group was instructed to respond honestly (neutral condition) while the second group was instructed them as if they are applicants who are follow employee selection test (applicants condition). Differential item functioning (DIF) test with Mantel-Haenzel test was employed. Analysis result suggests that 12 items are vulnerable to faking response that is spread out on four personality factors (extroversion factor, agreeableness, emotional stability and openness to new ideas).
