Aplikasi Teori Respon Butir Untuk Menguji Invariansi Pengukuran Psikologi Guna Keperluan Survei dan Seleksi Pekerjaan
Abstrak: This study aims was
exploring model that explain faking responses on the psychological scale
through item response theory modeling (IRT) and tested its goodness of fit.
This research use quasi-experimental design that manipulates participant
instructions to response Five Factors Personality Scale. In the first
instruction, participants were asked to give honest response to given scale,
while the second condition were asked to imagine as job applicants so they
consider to manipulate their response to
give positive impression. IRT based modeling was done on both types of response
by using partial credit model (PCM). Results of analysis suggest whether there
is no difference in threshold parameters between the two types of responses.
Additional analysis with differential item functioning (DIF) test found
inconsistent results. There are some items affected by DIF that indicated
participants who manipulated their response have probability of getting a high
score than others. Overall, this study shows that the nature invariance of IRT
modeling interrupted by faking response.
