The most important thing to emphasis is that this is a separate diagnosis from OCD - Obsessive Compulsive Disorder. OCD is an axis one disorder and is an excited disorder versus OCPD which is one of 10 personality disorder, so axis 2 disorder. I would say the main short hand way to differentiate between the two, the individual with Obsessive Compulsive Personality Disorder don't necessarily think that there is anything wrong. They do tend to be obsessive and compulsive and meaning that they are very focused on orderliness and things have to be done on a certain way. And they are very exact in paying a lot of attention to detail and these individuals can be very frustrating to interact with because they don't hold to their standard gesture for themselves, they also need a very specific set of behaviors and responses from all the people they interact with. And as I said, they don't really feel like their need for orderliness is excessive in any way. They think they are just being a certain level of perfect and keeping a certain level of excellence. But they demand this very specific level of functioning from everybody they interact with and it causing problems in relationships and where this is compared to OCD where individuals who have OCD Obsessive Compulsive Disorder, they are the ones who are mostly distressed by their symptoms and they know their behaviors are illogical and don't make any sense. But, they can't do anything to stop it. The individuals with OCPD, they don't think there is anything wrong and they don't really want to do anything to stop it until sometimes they keep having the same kinds of problems with other peoples over and over and over again and they will come into treatment to help understand why other people don't seem to be able to meet their standards. But, they don't think there is anything wrong with their standards and that is the main difference between OCPD and OCD.
