Examining DSM criteria for trichotillomania in a dimensional framework: implications for DSM-5 and diagnostic practice.

ABSTRACT:

Background

Diagnosis of trichotillomania (TTM) requires meeting several criteria that aim to embody the core pathology of the disorder. These criteria are traditionally interpreted monothetically, in that they are all equally necessary for diagnosis.
