Abstract
The present study explored relationships between the Dark Triad (Machiavellianism, narcissism, and psychopathy) and cluster B personality disorder (antisocial, borderline, histrionic, and narcissistic) features. A sample of 661 participants were recruited from a Midwestern university and Amazon Mechanical Turk. A series of t-tests were conducted to examine sex differences in the Dark Triad and cluster B personality disorders. Sex differences were found on all traits and disorders, with men significantly higher than women on Machiavellianism, psychopathy, and antisocial personality disorder, and women higher than men on borderline, histrionic, and narcissistic personality disorders. Zero-order correlations and linear regression analyses were conducted to examine the contribution of each Dark Triad trait to each personality disorder. Significant associations were found for all personality disorders, with at least one Dark Triad trait making a significant contribution to each disorder. The relevance of the present study to the workplace and politics was discussed.
Highlights
The past decade has seen a surge of research focusing on the „dark‟ personality traits: Machiavellianism, narcissism, and psychopathy
Many of the Dark Triad traits are represented across different forms of psychopathology, especially cluster B personality disorders, there has been limited research examining the unique and shared associations
6.2 Sex differences in the dark triad To test the first two hypotheses, a series of independent samples t-tests were conducted to determine if sex differences existed in mean scores for each of the Dark Triad traits and in T-scores for each of the cluster B personality disorder (PD) subscales
Summary
The past decade has seen a surge of research focusing on the „dark‟ personality traits: Machiavellianism, narcissism, and psychopathy. The term „Dark Triad‟ has been attributed to Paulhus and Williams [1], who attempted to explore the nature of this triad in a sample of 245 college students. They concluded that these traits were overlapping, yet. J Psychiatry Psychiatric Disord 2017; 1 (6): 317-326 distinct, constructs They used only a simple measure of personality traits (i.e., The Big Five) [2] and only its five major dimensions. The purpose of the present study was to explore relationships between the Dark Triad and the current cluster B personality disorders of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association [APA]) [6], to determine the relative contribution of the Dark Triad to these clinical constructs
