ality disorder and OCD are met, bo th diagnoses should be recorded.
Hoarding disorder. A diagnosis of hoarding disorder should be considered especially
when hoarding is extreme (e.g., accumulated st acks of worthless objects present a fire haz-
ard and make it difficult for others to walk through the house). When criteria for both ob-
sessive-compulsive personality disorder and ho arding disorder are met, both diagnoses
should be recorded. 
Other personality disorder s and personality traits. Other personality disorders may
be confused with obsessive-compulsive person ality disorder because they have certain
features in common. It is, therefore, important to distingu ish among these disorders based
on differences in their characteristic features. However, if an individual has personality
features that meet criteria for one or more personality disorders in addition to obsessive-
compulsive personality disorder, all can be diagnosed. Individuals with narcissistic per-
sonality disorder may also profess a commitmen t to perfectionism and believe that others
cannot do things as well, but these individuals are more likely to believe that they have
achieved perfection, whereas those with obse ssive-compulsive personality disorder are
usually self-critical. Individuals with narcissi stic or antisocial personality disorder lack
generosity but will indulge themselves, wher eas those with obsessive-compulsive person-
ality disorder adopt a miserly spending style toward both self and others. Both schizoid
personality disorder and obsessive-compulsive  personality disorder may be characterized
by an apparent formality and social detachme nt. In obsessive-compulsive personality dis-
order, this stems from discomfort with emot ions and excessive devotion to work, whereas
in schizoid personality disorder there is a fundamental lack of capacity for intimacy.
