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.

Self-esteem in patients with borderline and avoidant personality disorders

This study compared self-esteem in patients with avoidant personality disorder (APD) and borderline personality disorder (BPD). Patients diagnosed with one or more personality disorders answered the questionnaire Index of Self Esteem as part of a comprehensive evaluation within the setting of a treatment trial. Our hypotheses were that (1) both patients with APD and patients with BPD would report low levels of self-esteem, (2) patients with APD would report lower self-esteem than patients with BPD. We further expected that (3) patients with higher levels of depression would report lower levels of self-esteem, but that (4) both borderline and avoidant personality pathology would contribute to explained variance in self-esteem beyond what would be accounted for by depression. All of our hypotheses were supported. The results from our study showed a significant difference in self-esteem level between the two personality disorders, patients with APD reporting lower self-esteem than patients with BPD. Subjects with both disorders were measured to have self-esteem levels within the range that presumes clinical problems. Self-esteem represents an important quality of subjective experience of the self, and the study of self-esteem in PDs can offer new and important knowledge of PDs as self-pathology.

Psychotherapy for personality disorders: Short-term day hospital psychotherapy versus outpatient individual therapy – a randomized controlled study

This article describes the results of an eight-month follow-up investigation from a randomized controlled trial of day hospital psychotherapy (DHP) compared with outpatient individual psychotherapy (OIP) for patients with personality disorders (N=114). The patients were randomly assigned to either 18 weeks of day hospital treatment followed by long-term conjoint group and individual therapy (DHP), or outpatient individual psychotherapy (OIP). The main outcome measures were attrition rate, suicide attempts, suicidal thoughts, self-injury, psychosocial functioning, symptom distress, and interpersonal and personality problems. The study showed a low dropout rate and a moderate improvement on a broad range of clinical measures for both treatments. However, there was no indication of the superiority of one treatment over the other. Neither was there any indication that day hospital treatment was better for the most poorly functioning patients. Further studies will follow this group of patients for the next few years, the results of which may have implications for resource allocation and the organization of mental health services for patients with personality disorders.

Outpatient group psychotherapy: A valuable continuation treatment for patients with borderline personality disorder treated in a day hospital?: A 3-year follow-up study

Our objective was to investigate, in a naturalistic, prospective study, the follow-up status of patients with borderline personality disorder (BPD) treated with a combination of day treatment and subsequent outpatient group psychotherapy (G-group, n=12) and compare their status with that of patients with BPD treated in the same day hospital but without subsequent outpatient group therapy (Non-G-group, n=31). At follow-up an average of 34 months after discharge from the day hospital, the G-group patients had a moderate impairment in global health (HSRS), a low level of symptoms (GSI), a low rate of rehospitalization and suicide attempts, and a high rate of remission from substance use disorders. Compared with the Non-G-group, the G-group patients had a significantly higher HSRS and a significantly lower GSI at follow-up. In multivariate analyses controlling for background and treatment variables, number of months in work last year before admission and outpatient group therapy predicted a better HSRS at fol...

Mentalization as a moderator of treatment effects: Findings from a randomized clinical trial for personality disorders

Abstract Mentalization is the capacity to understand behavior as expressions of various mental states. It is assumed to be important for understanding the underlying psychopathology, the therapeutic process, and the outcome of therapy associated with patients with personality disorders (PDs). However, to date, empirical findings are scarce and inconsistent. This study aimed to examine whether the pre-treatment level of mentalization, operationalized as Reflective Functioning (RF), was associated with differential responses to two different treatment modalities and might predict clinical improvement. We analyzed data from a randomized clinical trial (Ullevål Personality Project). Seventy-eight patients with borderline and/or avoidant PD had been randomly assigned to either a step-down treatment program or outpatient individual psychotherapy. The step-down treatment comprised short-term day hospital treatment, followed by long-term, combined group and individual psychotherapy. RF was rated before treatment and after 36 months. Outcome measures were administered at baseline and after 8, 18, and 36 months. The moderator analyses indicated that patients with low RF levels at baseline responded better to outpatient individual psychotherapy than to the step-down treatment in terms of improvements in psychosocial functioning. Patients with medium-high RF levels responded equally well to both therapy formats. Determining which therapy format is appropriate for specific groups of patients can improve treatment efficiency. Therefore, our findings may have important clinical implications. Future research should address RF as a mediator of change.

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.

The impact of avoidant personality disorder on psychosocial impairment is substantial

Few studies have compared the psychosocial problems associated with different types of personality disorders (PDs). The aim of this study was to investigate the functional impairment and symptomatic distress associated with six PD diagnoses coded in DSM-IV: paranoid, borderline, avoidant, dependent, obsessive–compulsive PD and PD not otherwise specified, as well as a condition of non-psychotic symptom disorders with no PD. The study included 1023 patients from eight day treatment units specialized in the treatment of PDs. Eighty-one per cent had one or more PD diagnoses. At admission to day treatment, the patients were evaluated with respect to global functioning, symptomatic and interpersonal distress, education, quality of life, social support, legal problems and previous psychotic episodes and psychiatric hospitalizations. There were few differences in global functioning or symptomatic and interpersonal distress between patients with a single PD diagnosis. Avoidant PD and borderline PD was the diagnoses that contributed most to dysfunction in most variables when taking into account the presences of several co-occurrent PD diagnoses and axis I disorders. The psychosocial problems associated with avoidant and borderline PD were partly domain specific. The study indicates that avoidant PD is associated with severe dysfunction and subjective distress, at a level comparable to that of borderline PD. Avoidant PD deserves more attention, both with respect to the specific psychopathology and dynamics underlying the disorder and the development of treatment approaches.

Patients' characteristics, outcome and cost-benefit of hospital-based treatment for patients with personality disorder: A comparison of three different programmes

In this study we aimed (a) to ascertain whether a relationship exists between different treatment programmes and settings for personality disorder and patient characteristics; (b) to give an indication of treatment effects in three personality disordered populations admitted to different treatment contexts; and (c) to compare costs in relation to outcomes. We collected and compared three samples from one in-patient site (Cassel in England) and two day hospitals (Halliwick in England and Ulleval in Norway) on a number of demographic, diagnostic and other key clinical variables. Outcome in the areas of symptom severity (Symptom Checklist-90-R) and social adaptation (Social Adjustment Scale) was evaluated by comparing admission with discharge scores. Treatment costs for each sample were also estimated and compared. Significant differences were found on most baseline variables across the three sites. In general with regard to severity of psychopathology, the Halliwick sample was the most disturbed, Ulleval the least, with Cassel somewhat in between. No significant differences in improvement were found among the three sites, but treatment costs were considerably higher at Cassel than in the two day centres. The differences found in the three samples bear no clear relationship to context of treatment. These results suggest that referral of personality disorder for in-patient or day hospital treatment is less influenced by severity of problem than had previously been supposed and may depend more on availability of treatment facility.

Change in reflective functioning during psychotherapy—A single-case study

Abstract It has been suggested that deficits in mentalization are a core problem of borderline personality disorder and that enhancement of mentalization represents a central mechanism of change in psychotherapy with this group of patients. The present single-case study investigates changes in mentalization measured by the Reflective Functioning Scale on the Adult Attachment Interview and its relationship with clinical measures of psychopathology during a long-term psychotherapy. The usefulness of evaluating RF along three subdimensions, the object, content and process of RF, is underlined. Furthermore, it is argued that there is a complex interaction between RF and symptomatology that becomes evident when evaluating RF along the different subdimensions. Areas for future research clarifying the relationship between mentalization, psychotherapy and psychopathology are suggested.
