title = "Cross-Sectional Age Differences in the Dark Triad Traits in Two Japanese Samples",
abstract = "This study investigated the age differences in the Dark Triad (DT) traits with 2 independent samples. Personality was measured using the Short Dark Triad and the Dark Triad Dirty Dozen. Results showed a significant negative correlation between age and DT traits except for narcissism, which differed between the samples. Significant age-by-sex interaction effects were observed for Machiavellianism and the DT composite score, indicating that women showed a steeper downward age trend in dark personalities.",
