N2 - The DSM–5 introduced an alternative model of personality disorders that is predicated on the presence of personality dysfunction (Criterion A) and pathological personality traits (Criterion B). Recently, a member of the DSM–5 Personality and Personality Disorder Work Group—Morey—published a measure of Criterion A. Our study (Sleep, Lynam, Widiger, Crowe, & Miller, 2019, this issue) examined the performance of Morey’s (2017) Levels of Personality Functioning Scale—Self-Report (LFPS-SR) by testing its factor structure, relations with Axis I and II symptoms, and its incremental validity in predicting traditional personality disorders in comparison to Criterion B traits. In his response, Morey raised a number of issues regarding our examination of the LPFS-SR in relation to its factor structure, discriminant validity, and incremental validity. Moreover, he suggested our approach (i.e., pitting Criterion A vs. B) is emblematic of problems in the field that contributed to the relegating of the AMPD to Section III (on emerging measures and models). In our response, we answer his criticisms.
