TL;DR: The HiTOP promises to improve research and clinical practice by addressing the aforementioned shortcomings of traditional nosologies and provides an effective way to summarize and convey information on risk factors, etiology, pathophysiology, phenomenology, illness course, and treatment response.

TL;DR: The aims and current foci of the HiTOP Consortium, a group of 70 investigators working together to study empirical classification of psychopathology, are described, which pertain to continued research on the empirical organization of psychopathological constructs; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic.

TL;DR: It is demonstrated that Miller and Lynam's assertions that PPI-FD exhibits weak construct validity are sharply at odds with evidence that well-validated psychopathy measures detect both secondary and primary subtypes, and are inconsistent with most classic clinical descriptions of psychopathy.
