Samples that had the childhood traits of rigidity, extreme cautiousness, and perfectionism endured more severe food restriction and higher levels of exercise and underwent longer periods of underweight status. It may be that OCPD traits are an indicator of a more severe manifestation of AN which is harder to treat. Gambling Disorder
A majority of those with lifelong gambling disorder have some sort of personality disorder, and the most common personality disorder amongst them is obsessive compulsive personality disorder. OCPD has a strong comorbidity with individuals who have gambling disorder. A study of data collected in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions looked at pathological gambling and psychiatric conditions as defined by the DSM-IV. Of the surveyed population consistent with gambling disorder, 60.8% also had a personality disorder, with OCPD appearing most frequently at 30%. About 300,000 U.S citizens have both a gambling disorder and obsessive compulsive personality disorder; and yet, there is little research on the comorbidity of the two disorders. Those with gambling disorders and OCPD do, indeed, exhibit different behavioral patterns than those with gambling disorders alone. More research on the relationship between the disorders is thought to help uncover causes and develop treatments for patients. Mental Fatigue
Recently, in 2020, the connection between mental fatigue and OCPD was published for the first time, even though mental fatigue has been previously associated with identified characteristics of OCPD such as workaholic behavior and perfectionism. Other disorders and conditions
A diagnosis of OCPD is common with anxiety disorders, substance use disorders, and mood disorders.
