title: New diagnostic perspectives on obsessive-compulsive personality disorder and its links with other conditions.
abstract: OBJECTIVE
  This review examines the conceptualization of obsessive-compulsive personality disorder (OCPD), its epidemiology and efforts to better understand the relationships between OCPD and other conditions.
  
  
  RESULTS
  The alternative Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders conceptualization of OCPD is radically different in that it combines categorical and dimensional diagnostic approaches and introduces a hierarchy of diagnostic criteria. OCPD is one of the most common personality disorders in the general population. The relationship between OCPD and obsessive-compulsive disorder (OCD) is important, but to a large extent obfuscated by the overlap between their diagnostic criteria. Frequent changes in the OCPD diagnostic criteria make it difficult to ascertain the 'true' relationship between OCPD and OCD. It is not uncommon for OCPD to occur with anorexia nervosa, depression, hypochondriasis, certain other personality disorders and Parkinson's disease, but further research is necessary to understand the implications of these links.
  
  
  CONCLUSIONS
  OCPD is yet to be conceptualized consistently and in the manner that would make a clear and well supported distinction between its core and peripheral features. Future studies need to separate a genuine from overlap-driven co-occurrence of OCPD and other conditions, as that would give a better insight into the way in which OCPD relates to other disorders.
