What is Obsessive-Compulsive Personality Disorder?

This video describes Obsessive Compulsive Personality Disorder (OCPD). In the Diagnostic and Statistical Manual (DSM), OCPD is a Cluster C personality disorder, which is the anxious, fearful cluster. The other two personality disorders in Cluster C are Avoidant Personality Disorder and Dependent Personality Disorder. OCPD is often confused with obsessive-compulsive disorder (OCD). There is high comorbidity between these two disorders. If somebody has obsessive compulsive disorder, there is a 25% chance they would also qualify for a diagnosis of obsessive compulsive personality disorder. There are a number of key differences to differentiate them. One difference that stands out the most is that OCPD doesn't have obsessions or compulsions. We also see a lack of insight with OCPD more often than we do with OCD. Also, perfectionism is a key characteristic we see an OCPD that we don't always see in OCD.
The DSM symptom criteria include: preoccupation with details, order, schedules, and lists, perfectionism, excessive devotion to productivity, over-conscientiousness, difficulty in discarding objects that are worthless or are at the end of their useful life, reluctance to delegate tasks, a miserly spending style, and rigidity. OCPD is one of the more prevalent personality disorders. It tends to affect males to females at a rate of about two to one.
