Miller and Lynam’s (2017) commentary proved to be very helpful in clarifying that ralerting-CV and rcontrast-CV coefficient values reported in our study indicated that the Narcissistic Personality Inventory (NPI) yielded a trait profile much more closely aligned with expert ratings of Diagnostic and Statistical Manual of Mental Disorders (4th edition; DSM–IV) narcissistic personality disorder (NPD) than did other measures. The commentary gives us the opportunity to make it clear that our study was designed to demonstrate the clinical usefulness of Personality Inventory for DSM–5 (PID-5) domain and trait scales in profiling pathological narcissism. Thus, demonstrating the superiority/inferiority of the Pathological Narcissism Inventory (PNI) over the NPI was not among the aims of our study. The publication of the commentary also gives us the opportunity to clarify the reasons why we think that the interpretation of the ralerting-CV and rcontrast-CV coefficients deserves some cautions. As a final remark, we think that the time has come to move from personality disorder classifications based on “clinical wisdom” to a redefinition of personality pathology in terms of systems of traits.
