A comparison of DSM-III personality disorders in panic/agoraphobia and obsessive-compulsive disorder

One hundred eighty-seven patients meeting DSM-III criteria for panic disorder (161 with agoraphobia) and 51 patients meeting DSM-III criteria for obsessive-compulsive disorder (OCD) were assessed with the Personality Diagnostic Questionnaire (PDQ), a self-rating scale designed to assess axis II personality disorders and traits. The results showed that the personality profiles were similar between the two diagnostic groups and that the major personality characteristics identified in panic/agoraphobic patients, e.g., avoidant, dependent, histrionic, and borderline, were more pronounced in patients with OCD. These findings support our earlier suggestion of a nonspecific link between panic disorder/agoraphobia and personality disorder (PD)/traits.     

Bipolar obsessive-compulsive disorder and personality disorders

OBJECTIVES: Relatively few systematic data exist on the clinical impact of bipolar comorbidity in obsessive-compulsive disorder (OCD) and no studies have investigated the influence of such a comorbidity on the prevalence and pattern of Axis II comorbidity. The aim of the present study was to explore the comorbidity of personality disorders in a group of patients with OCD and comorbid bipolar disorder (BD). METHODS: The sample consisted of 204 subjects with a principal diagnosis of OCD (DSM-IV) and a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score>or=16 recruited from all patients consecutively referred to the Anxiety and Mood Disorders Unit, Department of Neuroscience, University of Turin over a period of 5 years (January 1998-December 2002). Diagnostic evaluation and Axis I comorbidities were collected by means of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Personality status was assessed by using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II). Socio-demographic and clinical features (including Axis II comorbidities) were compared between OCD patients with and without a lifetime comorbidity of BD. RESULTS: A total of 21 patients with OCD (10.3%) met DSM-IV criteria for a lifetime BD diagnosis: 4 (2.0%) with BD type I and 17 (8.3%) with BD type II. Those without a BD diagnosis showed significantly higher rates of male gender, sexual and hoarding obsessions, repeating compulsions and lifetime comorbid substance use disorders, when compared with patients with BD/OCD. With regard to personality disorders, those with BD/OCD showed higher prevalence rates of Cluster A (42.9% versus 21.3%; p=0.027) and Cluster B (57.1% versus 29.0%; p=0.009) personality disorders. Narcissistic and antisocial personality disorders were more frequent in BD/OCD. CONCLUSIONS: Our results point towards clinically relevant effects of comorbid BD on the personality profiles of OCD patients, with higher rates of narcissistic and antisocial personality disorders in BD/OCD patients.     

The comorbidity of DSM-III-R personality disorders in somatization disorder.

In order to understand psychiatric factors that complicate the medical management of somatizing patients, 94 subjects with known somatization disorder (SD) were evaluated for 13 personality disorders with the Structured Clinical Interview for DSM-III-R Personality Disorders. Referred from multiple primary care settings, the patient sample was predominantly female (85%), married (67%), high school graduates (64%), and had a mean age of 43. Structured interviews documented that 23.4% of SD patients had one personality disorder, and 37.2% had two or more disorders. The four most frequently identified personality disorders were avoidance 26.7%, paranoia 21.3%, self-defeating 19.1%, and obsessive-compulsive 17.1%. Interestingly histrionic personality disorder was identified in only 12.8% of the sample and antisocial personality disorder in 7.4%. In making the diagnosis of SD, health care providers need to avoid the common clinical impression that histrionic behavior often accompanies the disorder. Further research with SD patients is needed to examine the relationship of co-occurring personality disorders to symptom recurrence, health care utilization, and readiness for psychiatric referral.     

Quality of life in anxiety disorders: a comparison of obsessive-compulsive disorder, social anxiety disorder, and panic disorder

BACKGROUND: There is growing recognition that the anxiety disorders are disabling disorders associated with substantial morbidity and impaired quality of life (QOL). Nevertheless, there have been few studies comparing QOL across these conditions. SAMPLING AND METHODS: 337 outpatients with obsessive-compulsive disorder (OCD; n = 220), panic disorder (PD; n = 53), or social anxiety disorder (SAD; n = 64) were compared using a number of assessment scales to compare objective and subjective impairment in QOL. The association of QOL with symptom severity and comorbid depression was also assessed. RESULTS: The extent of impairment due to OCD, PD or SAD appears to be similar across the QOL scales. However, various domains are differentially affected in each of the disorders; OCD patients had more impairment in family life and activities of daily living; SAD patients had more impairment in social life and leisure activities, and PD patients were less able to avoid the use of nonprescribed drugs. QOL was lower in patients with increased symptom severity as well as in those with comorbid depression. CONCLUSIONS: While the extent of impairment appears similar across a number of different anxiety disorders, characteristic symptoms of each disorder may be associated with differential impairment of various domains of function, and may require specifically tailored interventions.     

Early-onset obsessive-compulsive disorder and personality disorders in adulthood

Obsessive-compulsive disorder (OCD) often emerges in childhood or adolescence. The aim of the present study was to evaluate whether adult patients with prepuberal onset differ from subjects with later onset in terms of personality disorder comorbidity. The Structured Clinical Interview for DSM-IV Axis II Disorders was used to assess 148 patients with a principal diagnosis of OCD according to the Structured Clinical Interview for DSM-IV Axis I Disorders. The following two subgroups of subjects were selected according to the age at onset of symptomatology: patients with an early-onset (< or =10 years), and patients with a later onset (> or =17 years). Of the 148 patients screened for the present study, 33 (22.3%) had an early onset and 1369 (46.6%) had a later onset. With regard to personality disorders, early-onset patients showed more OC personality disorders (OCPD) than later onset patients. Our finding suggests that OCD in childhood increases the risk for developing OCPD in adulthood, or that early-onset OCD and OCPD share a common pathogenesis.     

Standardized assessment of personality disorders in obsessive-compulsive disorder

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.     

DSM-IV obsessive-compulsive personality disorder: prevalence in patients with anxiety disorders and in healthy comparison subjects

The relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) has not yet been fully clarified. The aim of the present study was to analyze DSM-IV OCPD prevalence rates in OCD and panic disorder (PD) patients to test for the specificity of the OCPD-OCD link, and to compare them to OCPD prevalence in a control group of subjects without any psychiatric disorder. A total of 109 patients with a principal diagnosis of DSM-IV (SCID-I) OCD and 82 with PD were interviewed using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) in order to assess the prevalence of OCPD. All patients with a coexisting axis I diagnosis were excluded from the study to eliminate confounding factors when evaluating the association between prevalence rates of OCPD and anxiety disorder diagnoses. An exclusion criteria was also a Hamilton Depression Rating Scale (HAM-D) score >/=16. A sample of comparison subjects (age 18 to 65 years) without any psychiatric disorder was recruited from people registered with two general practitioners (GPs), whether or not they consulted the doctor, in order to evaluate OCPD prevalence rate in the community. A significant difference was found between the prevalence of OCPD in OCD (22.9%) and in PD (17.1%) on one hand, and that in the comparison sample (3.0%) on the other. No differences were found between the two psychiatric groups, even when splitting the samples according to gender. Our study failed to support the hypothesis of a specific relationship between OCPD and OCD; we confirmed the higher prevalence rate of this personality disorder in OCD subjects with regard to the general population, but we also confirmed the higher rate of OCPD in another anxiety disorder which is phenomenologically well characterized and different from OCD, such as PD.     

DSM-III personality disorders in obsessive-compulsive disorder: changes with treatment

Twenty-seven patients meeting DSM-III diagnostic criteria for obsessive-compulsive disorder (OCD) completed the Personality Diagnostic Questionnaire (PDQ; a self-rating scale designed to assess the axis II personality disorders [PDs] from the DSM-III) before and after 12 weeks of treatment with clomipramine. Treatment was accompanied with reduction on several personality variables, including the number of personality diagnoses assigned, the distribution of traits in the sample, and the number of items endorsed in each personality category. The data also showed that improvement in personality functioning was significantly greater in responders compared with nonresponders or partial responders. Further investigation of the relationship between personality and treatment outcome did not provide strong support for the notion that personality factors may have prognostic significance in the treatment of OCD. These findings suggest similarities and differences with panic/agoraphobia which are briefly discussed.     

A comparison of two interviews for DSM-III-R personality disorders

The study examined agreement between personality disorder diagnoses obtained using two structured interviews and the effect of depression on the diagnoses obtained. Twenty subjects were interviewed while depressed, using the Personality Disorder Examination and the Structured Clinical Interview for DSM-III-R Personality Disorder; both interviews are designed to yield DSM-III-R personality disorder diagnoses. Eighteen subjects were reinterviewed later, 17 after recovery. Diagnostic agreement between the two instruments for any disorder was fair (kappa = 0.38). Kappas for the personality disorder clusters ranged from 0.08 to 0.83. Kappas for individual personality disorders ranged from 0.18 for paranoid disorder to 0.62 for borderline disorder. While the depressive state did not consistently affect categorical diagnoses, dimensional scores tended to be higher when patients were depressed. A dimensional profile, in which scores on each disorder are generated for subjects, may be more reliable than categorical diagnoses derived from the same instrument.     

An explorative study on metacognition in obsessive-compulsive disorder and panic disorder

ObjectiveTo test the hypothesis that dysfunctional metacognitions might be a general vulnerability factor for anxiety disorder, metacognitive beliefs among patients with obsessive-compulsive disorder (OCD), patients with panic disorder (PD), and healthy subjects (HS) were studied. Correlations between metacognitive beliefs, OCD, and PD symptoms were also investigated.MethodsPatients with OCD (n = 114), patients with PD (n = 119), and HS (n = 101) were assessed with the Metacognition Questionnaire (MCQ).ResultsPatients with OCD and those with PD scored significantly higher than HS on the MCQ in 2 dimensions: negative beliefs about worry concerning uncontrollability and danger as well as beliefs about the need to control thoughts dimensions. No difference in MCQ scores was observed between the OCD and PD groups. The former 2 MCQ dimensions were positively correlated with the degree of indecisiveness in patients with OCD, whereas the MCQ negative beliefs about worry positively correlated with the average intensity of anticipatory anxiety in patients with PD.ConclusionsThe presence of dysfunctional metacognitions in both patients with OCD and those with PD suggests that such beliefs can represent not only generic vulnerability factors for anxiety disorders but also elements that contribute to maintaining the disorder, as evidenced by their associations with aspects of OCD and PD symptoms.     

The comorbidity of multiple personality disorder and DSM-III-R axis II disorders

Our ability to differentiate MPD from DSM-III-R Axis I disorders has become increasingly refined. Differentiation of MPD from the Axis II personality disorders is an area of more recent clinical investigation. MPD can be found comorbidity with many other psychiatric conditions. It is found in association with each of the DSM-III-R personality disorders. At the present time, however, we lack research data that define the prevalence of the comorbidity of MPD with the personality disorders. Objective study of this area is complicated by the paucity of instruments available to assess personality dimensions in the presence of a DD. In addition, the currently available personality inventories tend to overdiagnose BPD in patients with a high level of distress and acuity of symptoms. The diagnosis of a personality disorder in a patient with MPD is made on the basis of the assessment of the "whole" human being. It is based on the presence of a pervasive and relatively inflexible pattern of behaviors that reflects the individual predominant mode of being. The diagnosis of a personality disorder is not made on the basis of personality traits contained within any single alternate personality or groups of personalities. The personality disorders defined by DSM-III-R are a heterogeneous group of conditions whose individual etiologies reflect a complex interplay of constitutional, genetic, environmental, interpersonal, and psychodynamic factors. The interplay is variable and diverse between these determinants of the personality disorders and the traumatic forces that result in the development of a DD. For the Cluster A personality disorders (schizoid, schizotypal, paranoid), there is evidence supporting a relationship with specific psychotic illnesses. The combination of dissociative pathology with these personality disorders commonly results in a greater impairment of reality testing than in either condition alone. The Cluster B personality disorders (histrionic, narcissistic, borderline, antisocial) and Cluster C personality disorders (avoidant, compulsive, dependent, passive-aggressive) are believed to be primarily developmental disturbances. Comorbidity of these personality disorders with MPD involves consideration of the interaction of many developmental processes with the psychological impact of severe childhood trauma. Many MPD patients present with an apparent mixed personality profile consisting of an array of avoidant, compulsive, borderline, narcissistic, dependent, and passive-aggressive features. Although this article explores comorbidity of MPD with each of the personality disorders defined in DSM-III-R individually, it seems likely that a number of posttraumatic personality organizations can be defined that commonly coexist with MPD.(ABSTRACT TRUNCATED AT 400 WORDS)     

强迫型人格障碍与其他精神障碍的关系

强迫型人格障碍（OCPD）是指一种专注于追求秩序、完美以及精神和人际关系的控制,因而失去灵活性、开放性和效率的普遍模式.由于OCPD与其他精神障碍有很高的共病率,且它们之间的关系向来存在争议,因此现着重对已有相关研究进行归纳总结,以期为未来研究提供方向和建议.     

强迫障碍共病强迫型人格障碍的研究

目的:研究强迫型人格障碍(OCPD)在强迫障碍(OCD)中的共病情况,并研究OCD共病OCPD对OCD影响。方法:以69例门诊OCD患者为研究对象,采用DSM-Ⅳ轴Ⅱ障碍用临床定式检查(SCID-Ⅱ)研究强迫障碍患者的共病人格障碍(PD)情况,将研究对象分为2组:OCD共病OCPD组和OCD不共病OCPD组,对比研究2组间临床特征的不同。结果:79.7%强迫障碍患者合并有PD,C类中的OCPD和OCD共病率达43.5%。共病组较不共病组疾病严重程度更重,表现为发病年龄早、病程更长、强迫思维更严重。结论:OCPD和OCD关系密切,OCD共病OCPD是OCD严重程度的一个标志。     

An evaluation of DSM-III-R personality disorders.

This study evaluated the extent to which the features of personality disorders are organized into the 11 diagnoses proposed by DSM-III-R. The traits composing personality disorder diagnoses were identified in earlier studies. Seventy-nine traits were required to represent personality diagnoses. Self-report scales were developed to measure each trait. The factorial structure underlying the trait scales was examined in a sample of 158 patients with a primary diagnosis of personality disorder and a sample of 274 general population subjects. Eleven principal components were extracted from each data set and were rotated to the same oblique criterion. The decision to extract 11 components was based on a priori expectations derived from DSM-III-R. Factor comparability coefficients were computed to quantify the similarity of the 2 solutions. A high degree of similarity was observed between the factor structure in the clinical and general population samples, suggesting that features of personality pathology are continuous dimensions. Although a number of factors demonstrated a degree of resemblance to some DSM-III-R diagnostic categories, the overall correspondence was not strong. A second-order factor analysis failed to reproduce the 3 Axis II diagnostic clusters. The results do not support the categorical model used in DSM-III-R and they provide only limited support for DSM-III-R diagnostic concepts.     

DSM-III-R Axis I and II disorders in agoraphobic patients with and without panic disorder

Patients attending an inpatient phobia treatment program were diagnosed for DSM-III-R Axis I and II disorders, using the Structured Clinical Interview for DSM-III-R Disorders, and completed a set of self-report instruments. They were divided into 3 groups: (a) those who met the criteria for panic disorder with agoraphobia (n= 57), (b) those who met the criteria for agoraphobia without a history of panic disorder (n= 21), and (c) those who met criteria for other anxiety disorders, but not for panic/agoraphobia (n= 14). On Axis I, more of the panic with agoraphobia than of the agoraphobia without panic patients had obsessive-compulsive disorder. On Axis II, no significant differences between the agoraphobic patients with and without panic occurred. However, the number of hysterical traits was related to the presence of panic disorder among the agoraphobic patients. Avoidant and dependent traits were related to symptom severity.     

Gender-related distribution of personality disorders in a sample of patients with panic disorder.

OBJECTIVE: We examined gender differences in the frequency of DSM-IV personality disorder diagnoses in a sample of patients with a diagnosis of panic disorder (PD). METHOD: One hundred and eighty-four outpatients with a principal diagnosis of PD (DSM-IV) were enrolled. All patients were evaluated with a semi-structured interview to collect demographic and clinical data and to generate Axis I and Axis II diagnoses in accordance with DSM-IV criteria. RESULTS: Males were significantly more likely than females to meet diagnoses for schizoid and borderline personality disorder. Compared to males, females predominated in histrionic and cluster C diagnoses, particularly dependent personality disorder diagnoses. A significant interaction was found between female sex and agoraphobia on personality disorder (PD) distribution. CONCLUSIONS: Male PD patients seem to be characterized by more severe personality disorders, while female PD patients, particularly with co-morbid agoraphobia, have higher co-morbidity rates with personality disorders belonging to the 'anxious-fearful cluster'.     

The DSM-III-R personality disorders: an overview

The revision of DSM-III (DSM-III-R) includes substantial changes in the axis II personality disorders. The authors present and critically review these revisions and suggest directions for further research. The issues discussed include the multiaxial system, the use of a categorical rather than a dimensional format, the change from monothetic to polythetic criteria sets, the reduction in overlap among criteria sets, the decrease in the amount of unnecessary inferential clinical judgment required to make diagnoses, and the addition of two new personality disorders in an appendix. The criteria sets for many of the DSM-III personality disorders were also substantially revised in DSM-III-R. Changes in each of these are discussed in turn.     

DSM-III-R personality disorders in patients with eating disorders

The authors conducted a systematic examination of DSM-III-R personality disorders among 35 patients with eating disorders. Fifty-seven percent of the patients met the criteria for at least one axis II diagnosis; borderline, self-defeating, and avoidant were the most frequently assigned personality disorders. Forty percent of the patients were given two or more diagnoses, and 17% of the patients met criteria for five to seven diagnoses. No differences were found between patients with anorexia nervosa, anorexia and bulimia nervosa, and bulimia nervosa in the distribution of diagnoses or the frequency with which individual criteria (traits) were assigned.     

Comorbidity between obsessive-compulsive disorder (OCD) and personality disorders

The aims of the present study were to examine the frequency of personality disorders in 36 patients with obsessive-compulsive disorder (OCD), and to investigate whether patients with a coexisting personality disorder could be characterized by certain personality traits assessed by means of the Karolinska Scales of Personality (KSP). In total, 27 (75%) of the OCD patients fulfilled the DSM-III-R criteria for a personality disorder, and 13 patients (36%) had an obsessive-compulsive personality disorder. Subjects with a comorbid personality disorder had significantly higher scores on most of the KSP scales, including all anxiety scales, as well as scales measuring indirect aggression, irritability, guilt and detachment, whereas subjects without personality disorders did not differ significantly from healthy controls with regard to personality traits.
