Unveiling the Dark Triad in Indonesian Men: A Psychometric Odyssey

This research aims to confirm the suitability of the 27 items of the Indonesian version of the Short Dark Triad (SD3) measuring instrument to represent unobservable constructs. Respondents were Indonesian citizens of cis-heterosexual males with an age range of 18–60 years (n of 215). The questionnaire was distributed online. This research used the cross-cultural adaptation method and a confirmatory factor analysis (CFA) approach. The CFA results show that goodness-of-fit has been met, with a value of 0.947 for chi-square, 1.00 for CFI, 0.00 for RMSEA, 0.0356 for SRMR, and 1.04 for TLI. In the convergent validity test, the factor loading value of each construct indicator is greater than .50. In the reliability test, the Cronbach’s alpha and McDonald’s omega values for Machiavellianism were .649 and .649; for narcissism were .718 and .726; and for psychopathy were .733 and .740. It can be concluded that the SD3 in this property psychometric testing is valid and reliable, so they are ready to be tested on a much more varied population and sample.
