ABSTRACT We assessed 96 patients with obsessive-compulsive disorder for DSM-III personality disorder diagnoses with a standardized interview instrument (Structured Interview for the DSM-III Personality Disorders). Fifty patients (52%) met criteria for at least one personality disorder, with mixed, dependent, and histrionic personality disorders most frequently diagnosed. Compulsive personality disorder was diagnosed in only 6 patients (6%), 5 of whom had had onset of obsessive-compulsive symptoms before the age of 10 years, indicating that DSM-III compulsive personality disorder is not invariably a premorbid condition for the development of obsessive-compulsive disorder. Schizotypal personality disorder, at 5%, was found to be less common than in past samples, reflecting differences in either assessment methods or sampling.

    ABSTRACT: IntroductionThe onset of bipolar symptoms in patients with obsessive-compulsive disorders (OCD) is a common problem with important prognostic and therapeutic implications. Rates of comorbidity between the two disorders run as high as 30%. The aim of the present study was to explore socio-demographic and clinical differences between OCD patients with and without bipolar disorders to identify predictive factors that can guide treatment choices.

    ABSTRACT: Objective. The purpose of this paper is to provide evidence for the relationship between personality disorders (PDs), obsessive compulsive disorder (OCD), and other anxiety disorders different from OCD (non-OCD) symptomatology. Method. The sample consisted of a group of 122 individuals divided into three groups (41 OCD; 40 non-OCD, and 41 controls) matched by sex, age, and educational level. All the individuals answered the IPDE questionnaire and were evaluated by means of the SCID-I and SCID-II interviews. Results. Patients with OCD and non-OCD present a higher presence of PD. There was an increase in cluster C diagnoses in both groups, with no statistically significant differences between them. Conclusions. Presenting anxiety disorder seems to cause a specific vulnerability for PD. Most of the PDs that were presented belonged to cluster C. Obsessive Compulsive Personality Disorder (OCPD) is the most common among OCD. However, it does not occur more frequently among OCD patients than among other anxious patients, which does not confirm the continuum between obsessive personality and OCD. Implications for categorical and dimensional diagnoses are discussed.

    ABSTRACT: The nature of the relationship between obsessive-compulsive personality disorder (OCPD) and obsessive-compulsive disorder (OCD) has been the subject of considerable debate. The current study examined the hypothesis of a differential association of compulsive checking and washing behaviours with obsessive-compulsive personality traits within a nonclincal sample utilizing the Checking and Washing subscales of the Maudsley Obsessive-Compulsive Inventory (MOCI). Since checking behavior and obsessive-compulsive personality traits share a common future orientation, it was expected that checking behaviour would be more strongly related to OCPD traits than washing behavior. As hypothesized, checkers scored significantly higher than washers on several measures of obsessive-compulsive personality traits. In addition, the MOCI Checking subscale was more strongly associated with obsessive-compulsive personality measures than was the MOCI Washing subscale. The implications of these results in terms of etiology and treatment of OCD are discussed.
