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.

Interviews of Female Patients with Borderline Personality Disorder Who Dropped out of Group Psychotherapy

Abstract Premature termination from group psychotherapy continues to be a serious problem in the treatment of patients with borderline personality disorder (BPD). Qualitative research is regarded as an important means to shed light upon the complex dynamics leading to dropout. We conducted an interview study with patients having a diagnosis of BPD (n = 8) who dropped out from long-term group psychotherapy as a continuation therapy following intensive day treatment. The group therapists for these patients were interviewed as well (n = 12). The findings suggest the operation of many processes that contribute to dropout. Most significant appeared to be experiences of separation and loss of the day hospital that were not worked through and a failure of the group to regulate and contain the patients’ affects. To integrate patients at risk of premature termination it seems necessary to pay attention to the strong negative emotions that they experience in the group. A higher treatment intensity than weekly group sessions may help to promote more beneficial group processes.

A study of patients with personality disorder not otherwise specified.

BACKGROUND Personality disorder not otherwise specified (PD NOS) is a frequently applied diagnosis, but we lack knowledge of the clinical appearance of patients receiving the diagnosis. This study applied a large clinical sample (N = 1516) to investigate (1) the prevalence and diagnostic and clinical characteristics of patients with PD NOS defined according to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and (2) the prevalence and psychosocial impairment associated with different definitions of PD NOS. METHOD Patients from the Norwegian Network of Psychotherapeutic Day Hospitals diagnosed in accordance with the LEAD standard (Longitudinal, Expert, All Data) were evaluated on several clinical measures at admission and discharge from short-term treatment. RESULTS The DSM-IV PD NOS category was the third most frequent PD diagnosis. Seventeen percent of the total sample and 22% of those with PDs had a PD NOS diagnosis, with an average of 9 PD criteria. Patients with PD NOS were heterogeneous with respect to types of PD criteria, 41% were not subthreshold on any specific PD. The PD NOS patients were intermediate between patients with specific PDs and those with no PD regarding number of fulfilled PD criteria and several social and clinical variables. Alternative operationalizations of PD NOS, that is, subthreshold on at least 2 specific PDs or meeting a minimum of 10 PD criteria, resulted in lower prevalence rates and defined clinically more impaired patients. CONCLUSION The PD NOS defined according to DSM-IV has a high prevalence and seems to capture a group of patients with fewer PD criteria and less severe psychosocial impairment compared to patients with specific PDs. The findings indicate that the operational definition of PD NOS may have a strong impact on the prevalence and clinical appearance of patient receiving this diagnosis.

Different impulsivity profiles in borderline personality disorder and bipolar II disorder

INTRODUCTION Borderline personality disorder (BPD) and bipolar II disorder (BP II) share clinical characteristics including impulsivity. Their relationship is disputed. In this study, we investigated self-reported impulsivity in these patient groups and in a healthy control group. Effects of current mood state and of traumatic childhood experiences were explored. METHODS Twenty-five patients with BPD without comorbid bipolar disorder; 20 patients with BP II without comorbid BPD; and 44 healthy control subjects completed the UPPS questionnaire which yields assessments of four components of impulsivity: Urgency, Lack of Premeditation, Lack of Perseverance, and Sensation Seeking. Current mood state was rated using the Montgomery Asberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS). Traumatic childhood experiences were assessed using the Childhood Trauma Questionnaire (CTQ). Group differences in UPPS levels; and effects of mood state and CTQ score on UPPS scores in patients were investigated. RESULTS BPD patients showed significantly higher levels of Urgency and Lack of Perseverance than BP II patients and controls, and a significantly higher level of Lack of Premeditation than controls. BP II patients showed higher levels of Urgency and Lack of Perseverance than controls. In BP II, higher MADRS scores were associated with higher impulsivity scores. Also, higher CTQ scores were associated with higher Urgency scores in BP II. LIMITATIONS Relatively small sample size; cross-sectional assessment of influence of mood state. CONCLUSIONS BPD patients exhibited markedly elevated UPPS impulsivity scores compared with healthy controls and BP II patients, and the elevations were not related to current mood state. BP II patients showed moderately elevated impulsivity scores which were associated with a depressed mood state and to some extent with a history of childhood trauma. The findings suggest that BPD and BP II have different impulsivity profiles.

Personality functioning in patients with avoidant personality disorder and social phobia.

Avoidant personality disorder (APD) and social phobia (SP) are closely related, such that they are suggested to represent different severity levels of one social anxiety disorder. This cross-sectional study aimed to compare patients with APD to patients with SP, with particular focus on personality dysfunction. Ninety-one adult patients were examined by diagnostic interviews and self-report measures, including the Index of Self-Esteem and the Severity Indices of Personality Problems. Patients were categorized in three groups; SP without APD (n = 20), APD without SP (n = 15), and APD with SP (n = 56). Compared to patients with SP without APD, patients with APD reported more symptom disorders, psychosocial problems, criteria of personality disorders, and personality dysfunction regarding self-esteem, identity and relational problems. These results indicate that APD involves more severe and broader areas of personality dysfunction than SP, supporting the conceptualization of APD as a personality disorder as proposed for DSM-5.

Step-down versus outpatient psychotherapeutic treatment for personality disorders: 6-year follow-up of the Ulleval personality project.

BackgroundAlthough psychotherapy is considered the treatment of choice for patients with personality disorders (PDs), there is no consensus about the optimal level of care for this group of patients. This study reports the results from the 6-year follow-up of the Ullevål Personality Project (UPP), a randomized clinical trial comparing outpatient individual psychotherapy with a long-term step-down treatment program that included a short-term day hospital treatment followed by combined group and individual psychotherapy.MethodsThe UPP included 113 patients with PDs. Outcome was evaluated after 8 months, 18 months, 3 years and 6 years and was based on a wide range of clinical measures, such as psychosocial functioning, interpersonal problems, symptom severity, and axis I and II diagnoses.ResultsAt the 6-year follow-up, there were no statistically significant differences in outcome between the treatment groups. Effect sizes ranged from medium to large for all outcome variables in both treatment arms. However, patients in the outpatient group had a marked decline in psychosocial functioning during the period between the 3- and 6-year follow-ups; while psychosocial functioning continued to improve in the step-down group during the same period. This difference between groups was statistically significant.ConclusionsThe findings suggest that both hospital-based long-term step-down treatment and long-term outpatient individual psychotherapy may improve symptoms and psychosocial functioning in poorly functioning PD patients. Social and interpersonal functioning continued to improve in the step-down group during the post-treatment phase, indicating that longer-term changes were stimulated during treatment.Trial registrationNCT00378248.

Eating Disorders in a Large Clinical Sample of Men and Women with Personality Disorders

OBJECTIVE We assessed and compared the prevalence of anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS) across six Axis II groups (borderline, obsessive-compulsive, avoidant, dependent, paranoid, and personality disorder NOS) and patients with major depressive disorder (MDD) without personality disorders (PD). METHOD The sample included 3,266 consecutive and first admissions to 16 different treatment units in the Norwegian Network of Psychotherapeutic Day Hospitals between 1993 and 2009. All patients were interviewed with the SCID-II for DSM-III-R (prior to 1996) or DSM-IV (from 1996) and the MINI for Axis I disorders in accordance with the LEAD (longitudinal, expert, all-data) standard. RESULTS The prevalence of any ED in the PD sample was approximately 17% for women and 3% for men. A lower rate of ED (5%) was found for patients with MDD without PD. A significantly higher proportion of patients with borderline personality disorder were diagnosed with BN or EDNOS. The rate of AN was significantly elevated in female patients with obsessive-compulsive personality disorder. Men demonstrated significantly less diagnostic co-occurrence and no significant differential variation across PD groups or MDD. DISCUSSION Data which included a psychiatric comparison group showed less co-occurrence and non-significant variation across PD groups for men, but demonstrated a meaningful and specific pattern of comorbidity between ED and PD for women. There was an elevated risk of ED among female patients with PD, most pronounced for borderline. An almost five-fold higher rate of AN was found among women with obsessive-compulsive PD.

Some suggestions for the DSM-5 schizotypal personality disorder construct

This study relates to the schizotypal personality disorder (SPD) proposal of the upcoming fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by investigating the construct validity of SPD as defined by DSM-IV in a large sample of patients from the Norwegian Network of Personality-Focused Treatment Programs (N = 2619), assessed by structured diagnostic interviews and the Longitudinal, Expert All Data standard. We investigated factor structure and psychometric properties of the SPD criteria, as well as co-occurrence patterns between SPD and other PDs. Thirty-six patients were diagnosed with SPD and 513 patients (21%) endorsed at least 2 schizotypal criteria. We found that 2 factors were specific for SPD, a cognitive-perceptual factor (ideas of reference, magical thinking, and unusual perceptual experiences) and an oddness factor (odd thinking and speech, constricted affect, and odd appearance or behavior). The criteria belonging to these factors had appropriate psychometric properties. The criteria of the cognitive-perceptual factor were more strongly associated with borderline personality disorder (PD) than with the other PDs. We did not find support for a consistent factor that reflected interpersonal problems. The criteria that used to be part of this factor (suspiciousness, lack of friends or confidants, and excessive social anxiety) performed poorly as specific SPD criteria. SPD was more strongly associated with antisocial PD and paranoid PD than with the other PDs. We suggest that ideas of reference should be included explicitly under the schizotypal facet of cognitive dysregulation in DSM-5, with less emphasis on the social phobic aspects of this feature. Furthermore, there should be more emphasis on the cognitive aspects of suspiciousness in SPD, and it should be considered to split up the affectivity criterion into constricted affect and inappropriate affect, with the latter type of affect being the expression of problems with intersubjective regulation. Finally, it is suggested that interpersonal dysfunction is secondary to the 2 primary SPD factors. Therefore, the SPD narrative should start by describing eccentricity and cognitive-perceptual aberrations rather than interpersonal difficulties.

Avoidant Personality Disorder versus Social Phobia: The Significance of Childhood Neglect

Objectives Avoidant personality disorder (AvPD) and social phobia (SP) are common disorders both in the community and in clinical settings. Whether the two disorders represent different severity levels of social anxiety disorder is currently in dispute. The relationship between AvPD and SP is probably more complex than previously assumed. Several environmental, temperamental, and constitutional factors may play a role in the etiology of AvPD and SP. Better knowledge about childhood experiences may shed light on similarities and differences between the two disorders. The aim of this study was to compare self-reported childhood experiences in AvPD and SP patients. Design This is a cross-sectional multi-site study of 91 adult patients with AvPD and/ or SP. We compared patients with AvPD with and without SP (AvPD group) to patients with SP without AvPD (SP group). Methods The patients were examined using structured diagnostic interviews and self-report measures, including Child Trauma Questionnaire, Parental Bonding Instrument, and Adult Temperament Questionnaire. Results Both AvPD and SP were associated with negative childhood experiences. AvPD patients reported more severe childhood neglect than patients with SP, most pronounced for physical neglect. The difference between the disorders in neglect remained significant after controlling for temperamental factors and concurrent abuse. Conclusions The study indicates that childhood neglect is a risk factor for AvPD and may be one contributing factor to phenomenological differences between AvPD and SP.
