The case for using research on trait narcissism as a building block for understanding narcissistic personality disorder: A clarification and expansion.

We appreciate the thoughtful commentaries provided by Drs. Widiger (see record 2010-17135-006), Krueger (see record 2010-17135-007), and Blais and Little (see record 2010-17135-008) on our initial article (see record 2010-17135-004). These authors and prominent scholars have provided a number of compelling points both in support of and in opposition to the central tenets of our article. In what follows, we clarify and expand on our own position as it was interpreted in the commentaries of Krueger and Blais and Little. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
