Childhood maltreatment and personality disorders in adult patients with binge eating disorder

OBJECTIVE: To examine the association between retrospective reports of different types of childhood maltreatment and current personality disorders (PDs) in patients with binge eating disorder (BED). METHOD: A total of 116 consecutive out-patients with DSM-IV BED were assessed with diagnostic interviews and completed the Childhood Trauma Questionnaire to assess childhood maltreatment in five domains (emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect). RESULTS: Eighty-two percent of patients reported some form of childhood maltreatment and 30% met criteria for at least one PD. Emotional abuse was significantly associated with cluster C PD overall and specifically with avoidant PD. CONCLUSION: Reports of emotional abuse - but not other forms of maltreatment - were associated with greater likelihood of a PDs in patients with BED.     

The quality of the DSM-IV obsessive-compulsive personality disorder construct as a prototype category

The study evaluated the quality of the DSM-IV obsessive-compulsive personality disorder (OCPD) construct as a prototype category. A sample of 2237 patients from the Norwegian Network of Psychotherapeutic Day Hospitals was examined by a variety of psychometric analyses. A high number of OCPD patients (77%) had co-occurrent PDs, but only the co-occurrence with paranoid was significantly higher than expected. Exploratory factor analysis of the PD criteria indicated that OCPD consists of 2 dimensions. The first dimension, perfectionism, was constituted by OCPD criteria only and was significantly related to obsessive-compulsive disorder. The second dimension, aggressiveness, included 2 OCPD criteria, reluctance to delegate and stubbornness, but was also defined by criteria from paranoid, antisocial, and borderline PD. Confirmatory factor analysis of the OCPD criteria indicated a poor fit of both a unitary model and a 3-dimensional model. Overall, the OCPD criteria had poor psychometric properties. Although it seems that the quality of the DSM-IV OCPD as a prototype construct is insufficient, it may be improved by deleting the criteria hoarding behavior and miserliness. Alternative criteria could be related to problems in close relationships involving the need for predictability. Such revisions may add a third dimension to the 2 dimensions of perfectionism and aggressiveness.     

Longitudinal diagnostic efficiency of DSM-IV criteria for obsessive-compulsive personality disorder: a 2-year prospective study

OBJECTIVE: To examine the longitudinal diagnostic efficiency of the DSM-IV criteria for obsessive-compulsive personality disorder (OCPD). METHOD: At baseline, criteria and diagnoses were determined using diagnostic interviews, and blinded assessments were performed 24 months later with 550 participants. Diagnostic efficiency indices (conditional probabilities, total predictive power, and kappa) were calculated for each criterion determined at baseline, using the independent OCPD diagnosis at follow-up as the standard. RESULTS: Longitudinal diagnostic efficiencies for the OCPD criteria varied; findings suggested the overall predictive utility of 'preoccupied with details', 'rigid and stubborn', and 'reluctant to delegate'. CONCLUSION: These findings suggest the predictive validity of three cognitive-interpersonal OCPD criteria.     

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。     

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.     

Hoarding in obsessive-compulsive disorder and related disorders: a preliminary report of 15 cases

Hoarding, the repetitive collection of excessive quantities of poorly useable items of little or no value with failure to discard these items over time, is characterized in DSM-IV as a symptom of obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) but has, until recently, received scant empirical investigation. We describe the demographics, phenomenology, associated psychopathology and family history in 15 subjects presenting with hoarding behavior. Fifteen subjects were recruited from an OCD clinic and newspaper advertisement and assessed with the comprehensive Structured Clinical Interview for DSM-IV (SCID I and II), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), and a hoarding questionnaire (devised by the authors). The sample comprised 11 women and four men who hoarded a mean of seven item types, with a mean duration of 13.2 +/- 3.9 years (range 2-15 years). Their mean age was 41.8 +/- 14.3 years (range 20-65 years). The most common motive for hoarding was the fear of discarding items of practical value. Nine subjects met DSM-IV criteria for OCD, 9 met criteria for OCPD, for symptoms and behaviors other than hoarding, while six subjects met criteria for a putative OCD spectrum disorder (Tourette's, body dysmorphic disorder, trichotillomania). Six subjects reported little or no control over their hoarding, but only one subject saw her symptoms as an 'illness' warranting treatment. Pathological hoarding is usually a covert and chronic behavior causing distress and/or impairment, and may be related to OCD and OCPD. Hoarding may meet the criterion for a compulsion in DSM-IV, yet there is evidence to suggest that hoarding may manifest in a variety of other psychiatric conditions. While a range of pharmacologic and behavioral treatments have been tried, their effectiveness in managing hoarding behaviors requires additional research.     

Levels of childhood traumatic experiences and dissociative symptoms in extremely obese patients with and without binge eating disorder

Abstract

Background: It has been suggested that obese patients with binge eating disorder (BED) show higher levels of dissociation and childhood trauma.

Aim: This study assesses childhood trauma history and dissociative symptoms in obese patients with BED compared to obese patients without BED.

Methods: The 241 patients participating in the study had to meet obesity criteria. These patients were applicants for bariatric surgery and were consulted by a psychiatry service. Patients were separated into two groups that were accompanied by BED diagnoses according to structured clinical interviews administered according to the DSM-IV (SCID-I). Patients were assessed using the Dissociation Questionnaire (DIS-Q) and the Childhood Trauma Questionnaire (CTQ). The two groups of patients were compared.

Results: A total of 75 (31.1%) of the 241 obese patients were diagnosed with BED. The study showed that obese patients with BED had higher dissociative scores than those without BED (p < .05). The results showed higher total scores and two different types of childhood trauma (physical abuse and emotional abuse) in BED patients compared to non-BED patients (p < .05).

Conclusions: Clinicians should be fully aware of BED, dissociative symptoms and childhood traumatic experiences. These results show that, for at least a sub-group of obese patients, BED is associated with obesity and may be connected with dissociative symptoms and childhood physical abuse and emotional abuse.     

Convergent and discriminant validity of DSM-IV axis II personality disorder criteria in adult outpatients with binge eating disorder

The study objective was to evaluate the within-category cohesiveness and between-category overlap of DSM-IV axis II personality disorders (PDs) in outpatients with binge eating disorder (BED). Seventy adult outpatients with BED were reliably administered the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). Within-category interrelatedness of the criteria was evaluated by Cronbach's alpha and mean intercriterion correlations (MICs). Between-category criterion overlap was evaluated by examining intercategory mean intercriterion correlations between all pairs of PDs (ICMICs). Cronbach's alpha was .64 to .93 (mean, .77), the MIC was .17 to .52 (mean, .34), and the ICMIC was .11 to .39 (mean, .28). Our findings indicate that in outpatients with BED, the DSM-IV PD criteria sets have convergent validity (acceptable alpha value and MIC). Some degree of discriminant validity also exists: criteria for most DSM-IV PDs correlate better with each other (MIC) than with criteria for other PDs (ICMIC).

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.     

Borderline personality disorder and the misdiagnosis of bipolar disorder

Recent reports suggest bipolar disorder is not only under-diagnosed but may at times be over-diagnosed. Little is known about factors that increase the odds of such mistakes. The present work explores whether symptoms of borderline personality disorder increase the odds of a bipolar misdiagnosis. Psychiatric outpatients (n = 610) presenting for treatment were administered the Structured Clinical Interview for DSM-IV (SCID) and the Structured Interview for DSM-IV Personality for DSM-IV axis II disorders (SIDP-IV), as well as a questionnaire asking if they had ever been diagnosed with bipolar disorder by a mental health care professional. Eighty-two patients who reported having been previously diagnosed with bipolar disorder but who did not have it according to the SCID were compared to 528 patients who had never been diagnosed with bipolar disorder. Patients with borderline personality disorder had significantly greater odds of a previous bipolar misdiagnosis, but no specific borderline criterion was unique in predicting this outcome. Patients with borderline personality disorder, regardless of how they meet criteria, may be at increased risk of being misdiagnosed with bipolar disorder.     

Eating disorder symptoms and comorbid psychopathology among male and female veterans

Objective

Eating disorder (ED) symptoms have gone mostly unexamined among veterans. The current study assessed rates of bulimia nervosa (BN) and binge eating disorder (BED) symptoms and diagnoses and their associations with common comorbidities among male and female veterans.

Method

Participants were US military veterans who screened positive for trauma histories and/or a probable Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) posttraumatic stress disorder (PTSD) diagnosis (n= 499). Symptoms of PTSD were assessed using the Clinician-Administered PTSD Scale, and symptoms of EDs, mood, and substance use disorders were assessed using the Structured Clinical Interview for the DSM-IV.

Results

Lifetime rates of BN and BED diagnoses were comparable to civilian populations, and a considerable range of lifetime and current BN and BED symptoms were identified. In multivariate models, PTSD and depression severity were most consistently associated with BN and BED symptom severity, with depression most strongly associated with EDs for women.

Conclusions

Findings highlight the importance of screening for ED symptoms among male and female veterans, particularly those that present with PTSD and depression symptomatology. Future examinations of the temporal order of such relationships and the degree to which ED symptoms and associated symptoms impact veteran functioning are warranted.     

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.     

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.     

Acute and transient psychotic disorder: comorbidity with personality disorder

A study sample of 51 patients with acute and transient psychotic disorder (ATPD) (ICD-10) is presented. The findings suggest that, in hospital settings, ATPD is a non-frequent condition with onset in early adult life and most often associated with female sex, good premorbid social functioning and no or minor/moderate psychosocial stressors. The DSM-IV criteria distribute the patients into three diagnostic categories: schizophreniform disorder (41%), brief psychotic disorder (33%) and psychotic disorder not otherwise classified (25%). A high prevalence (63%) of personality disorders (PD) is revealed after recovery from the psychotic episode. The ATPD is not related to any specific PD, and in a substantial minority (37%) of cases no PD is found. The unspecified category is by far the most frequent PD in patients with ATPD. The sample will be followed up and reassessed.     

Obsessive compulsive personality disorder and obsessive compulsive disorder: clinical characteristics, diagnostic difficulties, and treatment.

BACKGROUND: The overlap between obsessive compulsive personality disorder (OCPD) and obsessive compulsive disorder (OCD) has received increasing recognition and continues to be a source of much debate. With the advent of new research methodologies, researchers have attempted to distinguish whether OCPD and OCD are two distinct phenomena that can co-occur or whether they are similar, overlapping constructs. METHODS: MEDLINE was used to systematically review the OCPD and OCD literature published between 1991 and 2004. RESULTS: Using the more stringent DSM-IV criteria, results from OCD clinical samples suggest that the majority of individuals with OCD (75%) do not have OCPD. Similarly, results from personality disorder samples suggest that the majority of individuals with OCPD (80%) do not have OCD. CONCLUSIONS: While there is evidence that OCD and OCPD are linked, the literature does not support either one as a necessary or sufficient component of the other.     

Factor analysis of the DSM-III-R borderline personality disorder criteria in psychiatric inpatients

OBJECTIVE: The goal of this study was to examine the factor structure of the DSM-III-R criteria for borderline personality disorder in young adult psychiatric inpatients. METHOD: The authors assessed 141 acutely ill inpatients with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. They used correlational analyses to examine the associations among the different criteria for borderline personality disorder and performed an exploratory factor analysis. RESULTS: Cronbach's coefficient alpha for the borderline personality disorder criteria was 0.69. A principal components factor analysis with a varimax rotation accounted for 57.2% of the variance and revealed three homogeneous factors. These factors were disturbed relatedness (unstable relationships, identity disturbance, and chronic emptiness); behavioral dysregulation (impulsivity and suicidal/self-mutilative behavior); and affective dysregulation (affective instability, inappropriate anger, and efforts to avoid abandonment). CONCLUSIONS: Exploratory factor analysis revealed three homogeneous components of borderline personality disorder that may represent personality, behavioral, and affective features central to the disorder. Recognition of these components may inform treatment plans.     

Longitudinal outcome in patients with bipolar disorder assessed by life-charting is influenced by DSM-IV personality disorder symptoms

Objectives:  Few studies have examined the question of how personality features impact outcome in bipolar disorder (BD), though results from extant work and studies in major depressive disorder suggest that personality features are important in predicting outcome. The primary purpose of this paper was to examine the impact of DSM-IV personality disorder symptoms on long-term clinical outcome in BD.
Methods:  The study used a 'life-charting' approach in which 87 BD patients were followed regularly and treated according to published guidelines. Outcome was determined by examining symptoms over the most recent year of follow-up and personality symptoms were assessed with the Structured Clinical Interview for DSM-IV (SCID-II) instrument at entry into the life-charting study.
Results:  Patients with better outcomes had fewer personality disorder symptoms in seven out of 10 disorder categories and Cluster A personality disorder symptoms best distinguished euthymic and symptomatic patients.
Conclusions:  These results raise important questions about the mechanisms linking personality pathology and outcome in BD, and argue that conceptual models concerning personality pathology and BD need to be further developed. Treatment implications of our results, such as need for psychosocial interventions and treatment algorithms, are also described.

The prevalence and structure of obsessive-compulsive personality disorder in Hispanic psychiatric outpatients

This study sought to confirm a multi-factor model of Obsessive-compulsive personality disorder (OCPD) in a Hispanic outpatient sample and to explore associations of the OCPD factors with aggression, depression, and suicidal thoughts. One hundred and thirty monolingual, Spanish-speaking participants were recruited from a community mental health center and were assessed by bilingual doctoral-level clinicians. OCPD was highly prevalent (26%) in this sample. Multi-factor models of OCPD were tested and the two factors - perfectionism and interpersonal rigidity - provided the best model fit. Interpersonal rigidity was associated with aggression and anger while perfectionism was associated with depression and suicidal thoughts.     

强迫症患者、强迫型人格障碍患者和健康对照者之间的认知灵活性和计划能力比较

背景：强迫症患者(Obsessive Compulsive Disorder, OCD)与强迫型人格障碍患者(Obsessive Compulsive Personality Disorder, OCPD)的认知功能还没有得到充分的研究。
　　目标：验证OCD和OCPD患者的认知灵活性和计划能力。
　　方法：本研究在德黑兰心理咨询门诊选定了25例OCD患者和20例OCPD患者,他们在既往两周都没有服药,并且从大学工作人员和当地社区居民中选定了25名健康对照者。对所有参与者均进行28项一般健康问卷(28-item version of the General Health Quesitonnaire, GHQ-28)、威斯康星卡片分类测验(Wisconsin Card Soritng Test, WCST)、和伦敦塔试验(Tower of London test, TOL)）。本研究运用WCTS的两个测量指标（持续错误数和完成分类数）评估认知灵活性以及TOL的三个测量指标（12个试验总共的移动次数、总应答时和计划时间）评估计划能力。
　　结果：2组患者的当前心理困扰程度显著高于对照组。在控制人口学因素和心理困扰水平后,OCD患者和OCPD患者在WCST测试中比对照组更容易出现持续性错误,而OCD患者（不包括OCPD患者）的完成分类数比对照组显著减少。OCD患者和OCDP患者都比对照组需要更多的移动次数来完成12项TOL任务,并且OCD患者比OCPD患者和对照组需要花更长的时间来完成任务。
　　结论：与健康对照组相比,OCD和OCPD患者的认知灵活性和计划能力都有所受损,并且OCD和OCPD患者之间的认知功能测试也存在一些差异。我们需要对OCD和OCPD患者进行长期随访研究评估在强迫症状严重性加重与减轻时认知功能的改变,从而决定此类认知评估指标对于强迫症是否有诊断或临床关联性。
