Development of personality disorders in children and adolescents with obsessive-compulsive disorder A 6- to 22-year follow-up study

Forty-seven people with admissions in childhood for obsessive-compulsive disorder (OCD) and 49 child psychiatric controls were followed up in young adulthood and assessed for DSM-III-R personality disorders with the Structured Clinical Interview for DSM-III-R Personality Disorders. The number of personality disorders in OCD patients did not differ significantly from the number in controls. The most common personality disorder was avoidant personality disorder (significantly more frequent than in controls), whereas obsessive-compulsive personality disorder (OCPD) was not found more often in the OCD group. Subjects with OCD in adulthood seemed to have OCPD more often than childhood OCD patients with no OCD at follow-up. In the whole group, histrionic personality disorders were more common in women than in men and OCPD more common in men than in women, whereas borderline personality disorder was most common among women in the OCD group. The presence of a personality disorder in adulthood could not be correlated with such childhood factors as social background, symptoms or age of onset of OCD.     

Parental psychopathology in child and adolescent obsessive-compulsive disorder

Purpose To identify the lifetime prevalence of obsessive-compulsive disorder (OCD) and other psychiatric diagnoses in parents of OCD pediatric patients as well as the frequency of onset of psychiatric disorders in the 6 months prior to evaluation. Methods Parents (n = 63) of 32 children and adolescents (20 males and 12 females; mean age of 13.3 ± 2.4) with OCD and parents of (n = 63) 32 age and sex-matched controls with no psychiatric diagnosis were examined. The semi-structured SCID-I was used to identify axis I psychiatric disorders and SCID-II to evaluate personality disorders. Results Mothers of patients had significantly more psychiatric diagnoses than control mothers (P = 0.001). Only parents of patients had diagnosis of OCD (P = 0.01) and psychiatric diagnosis (Adjustment Disorders, Major Depression, Anxiety Disorders) with onset during the 6 months prior to evaluation (P = 0.001). The duration of disease in children appeared to be related to development of morbidity in parents (P = 0.04). Parents of patients also showed a higher incidence of personality disorders (P = 0.01), in particular avoidant (6 versus 1 parents, P < 0.055) and obsessive-compulsive (9 versus 2 parents, P = 0.016) personality disorders. Conclusions The findings suggest that there may be an excess of psychopathology in parents of children with OCD as compared to parents of pediatric and non-psychiatric patients. Adjustment disorders with depressive and anxious symptoms are significantly more frequent in mothers of OCD children after the onset of the disease.     

OCD with comorbid OCPD: a subtype of OCD?

OBJECTIVE: The current study examined the validity of using comorbid obsessive-compulsive personality disorder (OCPD) to identify a subtype of individuals with obsessive-compulsive disorder (OCD). METHOD: Data for the current study were drawn from an ongoing, longitudinal study of the course of OCD and include intake assessments for 238 subjects with primary and current DSM-IV OCD who were treatment seeking. RESULTS: More than one fourth of the subjects (N=65, 27%) met criteria for comorbid OCPD. As compared to OCD-OCPD subjects, the OCD+OCPD subjects had a significantly younger age at onset of first OC symptoms (p=0.013), and a higher rate of symmetry and hoarding obsessions, and cleaning, ordering, repeating, and hoarding compulsions (all p's<0.01). Individuals with OCD+OCPD had higher rates of comorbid anxiety disorders (p=0.007) and avoidant personality disorder (p=0.006). The OCD+OCPD subjects also had significantly lower ratings of global functioning (p=0.001) and more impaired social functioning (p=0.004), despite a lack of significant differences on overall severity of OCD symptoms. CONCLUSIONS: Our findings indicate that individuals with both OCD and OCPD have distinct clinical characteristics in terms of age at onset of initial OC symptoms, the types of obsessions and compulsions they experience, and psychiatric comorbidity. Our findings, coupled with data from family studies showing a higher than expected frequency of OCPD in first degree relatives of OCD probands, suggest that OCD associated with OCPD may represent a specific subtype of OCD. Additional research is warranted to further establish the validity of this subtype.     

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.

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.     

强迫症伴强迫型人格障碍患者的临床表现

目的 评估强迫型人格障碍（OCPD）在强迫症（OCD）中的发病率,探讨伴OCPD的OCD患者的临床特征.方法 采用DSM-Ⅳ人格障碍临床定式检测手册（SCID-Ⅱ）中有关OCPD的诊断项目对260例OCD患者进行评估,据其是否符合OCPD诊断而将患者分为共病组（OCD＋ OCPD）和非共病组（OCD-OCPD）.对两者的临床特征、焦虑、抑郁水平等进行比较.结果 78例（30％）OCD患者符合OCPD的诊断;共病组有更多的物品污染、囤积以及高道德标准强迫思维和更多的检查、囤积和混合强迫行为等强迫症状,且共病组强迫行为严重程度、抑郁及特质焦虑水平显著高于非共病组,但两组首次出现强迫症状的年龄,有精神疾病家族史的比例以及自知力水平、状态焦虑水平等差异无统计学意义.结论 强迫型人格障碍与强迫症的重叠可能增加了其病理心理的严重程度.     

Children and adolescents with obsessive-compulsive disorder: the demographic and diagnostic characteristics of 61 Danish patients

To find children and adolescents with obsessive-compulsive disorder (OCD), a review was made of all the charts of the 4594 nonretarded, nonpsychotic patients treated at the Children's Psychiatric Hospital in Risskov, Denmark, as in- or outpatients from 1970 to 1986. Sixty-one children and adolescents (37 boys and 24 girls) fulfilled the DSM-III criteria for OCD. The frequency of OCD in a child psychiatric clientele was 1.33%, which supports earlier findings. Only 8 of the 61 children were actually discharged with a diagnosis of OCD (ICD-8 diagnosis). Most children were diagnosed as neurosis infantilis and about one fifth received a diagnosis of maladjustment. The possible reasons for this are discussed. It is concluded that it is hardly a matter of underdiagnosing OCD, but more likely an attempt to look upon the obsessive-compulsive symptoms as transient phenomena and perhaps an unwillingness among clinicians to use the diagnosis of OCD, which is often connected with a bad prognosis. Boys and girls with OCD did not differ significantly on important demographic items.     

Obsessive-compulsive and eating disorders: comparison of clinical and personality features

Abstract   The aim of the present study was to determine whether anorexia nervosa (AN), bulimia nervosa (BN) and obsessive-compulsive disorder (OCD) share clinical and psychopathological traits. The sample consisted of 90 female patients (30 OCD; 30 AN; 30 BN), who had been consecutively referred to the Department of Psychiatry, University Hospital of Bellvitge, Barcelona. All subjects met DSM-IV criteria for those pathologies. The assessment consisted of the Maudsley Obsessive-Compulsive Inventory (MOCI), Questionnaire of obsessive traits and personality by Vallejo, Eating Attitudes Test-40 (EAT-40), Eating Disorder Inventory (EDI), and Beck Depression Inventory (BDI). ancova tests (adjusted for age and body mass index) and multiple linear regression models based on obsessive-compulsiveness, obsessive personality traits and perfectionism, as independent variables, were applied to determine the best predictors of eating disorder severity. On ancova several significant differences were found between obsessive-compulsive and eating-disordered patients (MOCI, P  < 0.001; EAT, P  < 0.001; EDI, P  < 0.001), whereas some obsessive personality traits were not eating disorder specific. A total of 16.7% OCD patients presented a comorbid eating disorder, whereas 3.3% eating disorders patients had an OCD diagnosis. In the eating disorder group, the presence of OC symptomatology was positively associated ( r  = 0.57, P  < 0.001) with the severity of the eating disorder. The results were maintained after adjusting for comorbidity. Although some obsessive-compulsive and eating disorder patients share common traits (e.g. some personality traits especially between OCD and AN), both disorders seem to be clinically and psychopathologically different.     

Obsessive-compulsive disorder in children and adolescents: predictors in childhood for long-term phenomenological course

Prediction of the phenomenological course of obsessive-compulsive disorder (OCD) in adulthood was determined in 47 probands referred in childhood for in- or outpatient treatment for OCD. The only factor that predicted a poor outcome, defined as the presence of OCD in adulthood, was severity of OCD in childhood, as measured by the duration of the obsessive-compulsive symptoms. More females than males had an episodic course of OCD. However, just as many females as males had OCD, either chronically or episodically, in adulthood. Age of onset did not predict the phenomenological course of OCD.     

Association between cognitive impairments and obsessive-compulsive spectrum presentations following traumatic brain injury

This study examined the association between self-reported obsessive-compulsive spectrum symptomatology and cognitive performance in a sample of patients with traumatic brain injury (TBI). Twenty-four adults with a moderate-severe TBI accessing a community brain injury rehabilitation service were recruited. Age ranged between 19 and 69 years. Participants completed a battery of neuropsychological tasks assessing memory, executive functioning, and speed of information processing. Self-report questionnaires assessing obsessive-compulsive (OC) symptoms and obsessive-compulsive personality disorder (OCPD) traits were also completed. Correlational analyses revealed that deficits in cognitive flexibility were associated with greater self-reported OC symptomatology and severity. Greater OC symptom severity was significantly related to poorer performance on a visual memory task. Verbal memory and speed of information processing impairments were unrelated to OC symptoms. Performance on tasks of memory, executive functioning, and speed of information processing were not associated with OCPD traits. Overall, results indicate that greater OC symptomatology and severity were associated with specific neuropsychological functions (i.e., cognitive flexibility, visual memory). OCPD personality traits were unrelated to cognitive performance. Further research is needed to examine the potential causal relationship and longer-term interactions between cognitive sequelae and obsessive-compulsive spectrum presentations post-TBI.     

Obsessive-compulsive disorder comorbid with borderline personality disorder: A long-term case study

Abstract Three case reports of patients with borderline personality disorder (BPD) and obsessive-compulsive disorder (OCD) for more than 10 years are used to illustrate the relationship between OCD and borderline pathology. The recognizable features of the obsessive-compulsive symptoms in these reports are: (i) pervasiveness, the symptomatic overlap of obsessive-compulsive symptoms; (ii) poor insight and resistance; and (iii) obsessive control evident in personal relationships. These features are manifestations of OCD psychopathology as well as of a personality disorder. The symptoms with these features are located hypothetically towards the severe end of the symptomatic spectrum of OCD. The comorbidity is not a simple relationship, and the symptomatology of the comorbid patient is derived from OCD pathology linked with the personality disorder rather than from independent BPD pathology.     

Utility of the Leyton Obsessional Inventory to distinguish OCD and OCPD

The Leyton Obsessional Inventory (LOI) is a self-report questionnaire that assesses obsessional symptoms. The ability of the LOI to distinguish between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) has not been adequately addressed. Our purpose is to identify dimensions of obsessional symptoms from the LOI and determine how well they distinguish between OCD and OCPD. The LOI was completed by 488 participants diagnosed by trained clinicians. Factor analysis was performed on responses to the interference items of the LOI. The relationship between the factors, OCD and OCPD was evaluated using logistic regression. Five factors underlying the LOI were identified: (I) obsessional ruminations and compulsions, (II) ordering and arranging, (III) organizing activities, (IV) contamination, and (V) parsimony. Factors I, III, and IV were strongly associated with OCD. Only Factor II was associated with OCPD. Factor IV was negatively associated with obsessive-compulsive personality traits. LOI factors are useful in discriminating between OCD and OCPD. Obsessional ruminations and compulsions, organizing activities, and contamination fears may indicate OCD, and ordering and arranging symptoms may indicate OCPD rather than OCD. Parsimony may indicate neither disorder, and contamination, the absence of OCPD traits compared with the other LOI factors. These findings may contribute to effective diagnosis and treatment by allowing the LOI to screen for OCD and OCPD in a population exhibiting obsessional symptoms and traits.     

Normalization of personality characteristics in patients with incapacitating anxiety disorders after capsulotomy

The personality characteristics of 24 consecutive patients undergoing psycho-surgery for incapacitating anxiety disorders were assessed prospectively using a self-report personality inventory. The main findings were: absence of negative personality changes after surgery, significant postoperative changes towards normalization on the majority of the scales, and significant symptomatic relief in 80% of the cases. The changes on scales reflecting anxiety proneness were conspicuous in patients suffering from "pure" anxiety disorders, as compared with those suffering from obsessive-compulsive disorder (OCD). In OCD patients, correlations were obtained between changes in brain metabolism studied with positron emission tomography and changes in personality scores. It is concluded that negative personality changes are not likely to occur after capsulotomy.     

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.     

Comorbid obsessive-compulsive personality disorder in obsessive-compulsive disorder (OCD): a marker of severity

Introduction

Comorbid obsessive-compulsive personality disorder (OCPD) is well-described in obsessive-compulsive disorder (OCD). It remains unclear, however, whether OCPD in OCD represents a distinct subtype of OCD or whether it is simply a marker of severity in OCD.

Materials and methods

The aim of this study was to compare a large sample of OCD subjects (n = 403) with and without OCPD on a range of demographic, clinical and genetic characteristics to evaluate whether comorbid OCPD in OCD represents a distinct subtype of OCD, or is a marker of severity.

Results

Our findings suggest that OCD with and without OCPD are similar in terms of gender distribution and age at onset of OC symptoms. Compared to OCD − OCPD (n = 267, 66%), those with OCD + OCPD (n = 136, 34%) are more likely to present with the OC symptom dimensions which reflect the diagnostic criteria for OCPD (e.g. hoarding), and have significantly greater OCD severity, comorbidity, functional impairment, and poorer insight. Furthermore there are no differences in distribution of gene variants, or response to treatment in the two groups.

Conclusion

The majority of our findings suggest that in OCD, patients with OCPD do not have a highly distinctive phenomenological or genetic profile, but rather that OCPD represents a marker of severity.     

Personality disorders in patients with obsessive-compulsive disorder in Japan

A total of 75 patients with obsessive-compulsive disorder (OCD) were studied in order to investigate the characteristics of OCD symptoms and the comorbidity of personality disorders (PD). Contamination obsessions and checking compulsions were most commonly found in patients, of whom 53% met the criteria for at least one PD. Among comorbid PD, the anxious-fearful (cluster C) PDs, such as avoidant, obsessive-compulsive and dependent PD, were most prevalent, followed by the odd-eccentric (cluster A) PDs, such as paranoid and schizotypal PD. The patients with PD had more severe social maladaptation and concurrent depressive and anxious symptoms than the patients without any PD, despite the similar severity of OCD symptoms. These results are consistent with those reported in the Western world, and are considered to be relatively stable cross-culturally.     

Cross-cutting issues and future directions for the OCD spectrum

The research planning agenda for DSM-V examined possible similarities in phenomenology, comorbidity, familial and genetic features, brain circuitry, and treatment response between obsessive-compulsive disorder (OCD) and several related disorders that are characterized by repetitive thoughts or behaviors. Such data support a re-examination of the DSM-IV-TR classification of OCD and the anxiety disorders, with possible inclusion of a group of obsessive-compulsive spectrum disorders (OCSDs) in DSM-V. Various disorders were systematically examined for inclusion in such a grouping, and later a smaller number were determined to meet threshold criteria for inclusion in the OCSDs. The disorders that were originally examined included OCD, obsessive-compulsive personality disorder (OCPD), Tourette's syndrome (TS) and other tic disorders, Sydenham's chorea, Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS), trichotillomania (TTM), body dysmorphic disorder (BDD), autism, eating disorders, Huntington's and Parkinson's disease, impulse control disorders, as well as substance and behavioral addictions. Certain disorders such as BDD, OCPD, TS, and TTM share many commonalities with OCD in phenomenology, comorbidity, familial and genetic features, brain circuitry, and treatment response. Other disorders, such as the impulse control disorders (ICDs) share some common features with OCD, but also differ in many ways as well. The articles presented in this issue of Psychiatry Research are a result of this international collaboration, which examined diagnostic and classification issues of OCSDs for DSM-V in a conference titled “The Future of Psychiatric Diagnosis: Refining the Research Agenda: Obsessive-Compulsive Behavior Spectrum” held in June 2006 at the American Psychiatric Association's headquarters in Arlington, VA.     

An integration of the DSM-III and ICD-8 by global severity assessments for measuring multidimensional outcomes in general hospital psychiatry

A multiaxial classification system has been developed in which three ICD-8 derived axes of psychiatric syndromes, personality disorders and somatic syndromes, and two DSM-III axes of psychosocial stressors and social functioning have been included. Global assessment scales were annexed the three ICD-8 axes. This DSM-III/ICD-8 system was used for registration of 880 consequetively admitted psychiatric patients in a general hospital setting. The results showed that six psychiatric syndromes (substance use disorders, schizophrenia, manic-depressive psychosis, reactive psychosis, neurosis, and adjustment reactions) were responsible for 80% of the diagnostic variance. Of these syndromes, manic-depressive psychosis had the highest improvement rate both concerning symptoms and social functioning. Manic-depressive psychosis had also the lowest coefficient of variation in the stay in hospital indicating a high degree of homogeneity in accordance to the diagnose-related group system. However, patients within the categories of reactive psychosis and neurosis who received antidepressants also had a low coefficient of variation, although the neurotics were significantly more depressed than the manic-depressives at discharge from hospital.
