Intimate Partner Cyberstalking: Exploring Vulnerable Narcissism, Secondary Psychopathy, Borderline Traits, and Rejection Sensitivity

Intimate partner cyberstalking refers to the monitoring and controlling of an intimate partner through technologies. Unlike the cyberstalking of strangers, less is known about the motives and perpetration of intimate partner cyberstalking. In this study, we explore how vulnerable narcissism, secondary psychopathy, and borderline traits (i.e., the "Vulnerable Dark Triad") and rejection sensitivity relate to the perpetration of intimate partner cyberstalking. Participants (N = 278; 58 percent women) were recruited through social media and completed an anonymous online questionnaire. Positive correlations were observed between vulnerable narcissism, secondary psychopathy, borderline traits, rejection sensitivity, and intimate partner cyberstalking. Borderline traits moderated the relationship between participant sex (men and women) and intimate partner cyberstalking, and women with high borderline traits were most likely to cyberstalk intimate partners. Lastly, there was a significant indirect effect of vulnerable narcissism on intimate partner cyberstalking through rejection sensitivity. These findings highlight the importance of relational insecurity and rejection sensitivity in intimate partner cyberstalking and provide useful directions for future research exploring cyberstalking behaviors in intimate relationships.
