Antisocial personality traits as potential risk factors for cyberstalking: only aspects of psychopathy and narcissism matter

Cyberstalking is defined as the repeated pursuit of an individual using the Internet. The current study examined the relationship between Dark Triad constructs and cyberstalking among a large sample of adults (<i>N</i> = 1724) while addressing several limitations of previous research. Each construct was assessed using a validated measure; a newer measure of Machiavellianism was used to ensure that psychopathy and Machiavellianism could be distinguished; and separate models were run for each trait to avoid interpreting residuals from multivariate models. After controlling for age and sex, only the antisocial facet of psychopathy (early and repeated antisocial behaviour; odds ratio, <i>OR</i> = 2.74, 95% confidence interval, CI [1.73, 4.36]) and grandiose narcissism (inflated self-esteem and antagonism; <i>OR</i> = 1.27, 95% CI [1.08, 1.50]) were significantly related to cyberstalking perpetration within the past 12 months. While psychopathy and narcissism may be important factors for understanding antisocial behaviour, Machiavellianism appears to have limited predictive and practical utility.
