Personality disorders in the community: results from the Australian National Survey of Mental Health and Wellbeing Part II. Relationships between personality disorder, Axis I mental disorders and physical conditions with disability and health consultations.

BACKGROUND: The aims of this study were threefold. First, to ascertain whether personality disorder (PD) was a significant predictor of disability (as measured in a variety of ways) over and above that contributed by Axis I mental disorders and physical conditions. Second, whether the number of PD diagnoses given to an individual resulted in increasing severity of disability, and third, whether PD was a significant predictor of health and mental health consultations with GPs, psychiatrists, and psychologists, respectively, over the last 12 months. METHOD: Data were obtained from the National Survey of Mental Health and Wellbeing, conducted between May and August 1997. A stratified random sample of households was generated, from which all those aged 18 and over were considered potential interviewees. There were 10,641 respondents to the survey, and this represented a response rate of 78 %. Each interviewee was asked questions indexing specific ICD-10 PD criteria. RESULTS: Five measures of disability were examined. It was found that PD was a significant predictor of disability once Axis I and physical conditions were taken into account for four of the five disability measures. For three of the dichotomously-scored disability measures, odds ratios ranged from 1.88 to 6.32 for PD, whilst for the dimensionally-scored Mental Summary Subscale of the SF-12, a beta weight of -0.17 was recorded for PD. As regards number of PDs having a quasi-linear relationship to disability, there was some indication of this on the SF-12 Mental Summary Subscale and the two role functioning measures, and less so on the other two measures. As regards mental consultations, PD was a predictor of visits to GPs, psychiatrists and psychologists, over and above Axis I disorders and physical conditions. CONCLUSION: The study reports findings from a nationwide survey conducted within Australia and as such the data are less influenced by the selection and setting bias inherent in other germane studies. However, it does support previous findings that PD is a significant predictor of disability and mental health consultations independent of Axis I disorders and physical conditions.

[Personality disorders related to schizophrenia].

Personality disorders related to schizophrenia were described since Kraepelin's works. According to the DMS III-R those disorders are gathered into the A cluster of personality disorders consisting in: schizotypal, schizoid and paranoid personality disorders. Schizotypal and paranoid personalities are biologically linked to schizophrenia and support the concept of "schizophrenia spectrum". Until now such a link is not found between schizoid personality and schizophrenia. Future research in the field of those personality disorders will bring a better knowledge in the pathogenesis of schizophrenia.

Personality disorders in bipolar and depressive disorders.

The association of mood disorders with personality disorders (PDs) is relevant from a clinical, therapeutic and prognostic point of view. To examine this issue, we compared the prevalence of DSM-III-R personality disorders assessed with SCID-II in patients with depressive (n = 117) and bipolar (n = 71) disorders both recovered from a major depressive index episode that needed hospital admission. PDs prevalence and comorbidity with axis I were calculated. Avoidant PD (31.6%) (O.R. = 1.7, C.I. = 1.06-2.9. P < 0.01), borderline PD (30.8%) and obsessive-compulsive PD (30.8%) were the most prevalent axis II diagnoses among patients with depressive disorder. In bipolar disorder group, patients showed more frequently obsessive-compulsive PD (32.4%), followed by borderline PD (29.6%) and avoidant PD (19.7%). Avoidant PD showed a trend toward being significantly more prevalent among depressives (P < 0.07). A different pattern of PDs emerges between depressive and bipolar patients.

The prevalence of cyclothymia in borderline personality disorder.

Sixty patients with personality disorders were evaluated by several different diagnostic instruments to determine the prevalence of cyclothymia in borderline personality disorder (BPD) and in other personality disorders (OPD). Cyclothymia occurred more frequently in BPD than in OPD, regardless of which diagnostic system was used. In contrast, the prevalence of major, minor, and intermittent depression, hypomania, and bipolar disorder was not significantly different in BPD as compared with OPD. Cyclothymic borderlines and noncyclothymic borderlines could not be distinguished on behavioral or functional measures. These results have implications for the diagnostic validity of both BPD and cyclothymia.

Schizotypal personality disorder in individuals with and without schizophrenic relatives: similarities and contrasts in neurocognitive and clinical functioning.

Schizophrenia-spectrum disorders may reflect the genotype for schizophrenia. One such disorder, Schizotypal Personality Disorder (SPD), was examined as a function of family history of schizophrenia. Clinical profiles and neurocognitive functioning were evaluated in 25 schizotypal subjects (10 SPD with schizophrenic relatives and 15 SPD without schizophrenic relatives), and in 24 normal controls. The primary finding is that vigilance performance was similarly impaired in both SPD groups. An additional neurocognitive impairment, comprehension of grammatical constructions, was observed only in the SPD group with schizophrenic relatives. Of interest, the clinical profiles of the two SPD groups did not differ significantly. These results suggest that schizotypal personality disorder is associated with a continuum of neurocognitive vulnerability that increases as a function of family history of schizophrenia.

[Psychotherapeutic treatment of personality disorders].

Treating patients with personality disorders presents a major challenge due to their maladaptive interpersonal styles which affect the therapeutic relationship. A number of therapeutic approaches using psychodynamic, behavioural, and other origins have been developed to treat patients with personality disorders, most of them dealing with borderline personality disorder. Overall, only a few controlled therapy studies have been carried out to document therapy effectiveness. However, available research indicates that psychotherapy has substantial effects even in personality disorders. From a vast literature based on case reports, therapeutic recommendations are presented for specific personality disorders.

Treatment of borderline personality disorder with risperidone.

BACKGROUND: Of the various Axis II disorders, borderline personality disorder (BPD) is among the more critical to treat. There are at present few results in terms of clinical outcome with the psychotropic agents available. Possible targets for pharmacotherapy are affective symptoms, cognitive disturbances, and impulsive, self-injurious behaviors. In previous studies, atypical antipsychotics at low-to-moderate doses provided symptom reduction with good tolerability. Our purpose was to assess the efficacy of risperidone in BPD, focusing on its effects on impulsive-aggressive behavior. METHOD: Fifteen BPD outpatients (DSM-IV diagnosis) with prominent histories of aggressive behavior were included in an 8-week open-label study with risperidone at low-to-moderate doses. Axis II codiagnoses included antisocial personality disorder (N = 4). Exclusion criteria included current Axis I diagnosis or any major medical or neurologic illness. Efficacy measures were the 21-item Hamilton Rating Scale for Depression, the Brief Psychiatric Rating Scale, the DSM-IV Global Assessment of Functioning, and the self-rated Aggression Questionnaire. Evaluations were carried out at baseline and at the end of the treatment. RESULTS: Thirteen patients completed the trial; 2 patients dropped out because of lack of compliance. Final mean dose of risperidone was 3.27 mg/day. There was a significant (p = .0057) reduction in aggression based on Aggression Questionnaire scores. This amelioration was coupled with an overall improvement, including a reduction in depressive symptoms and an increase in energy and global functioning. CONCLUSION: Risperidone at low-to-moderate doses can improve BPD symptomatology. Further studies are needed to explore the efficacy of risperidone versus placebo as well as in comparison to other potential treatments for BPD.

Posttraumatic stress disorder in primary care with special reference to personality disorder comorbidity.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a common and disabling disturbance in primary care. Few studies have been carried out in primary care samples and none have taken into consideration the association between PTSD and personality disorder. AIM: To describe prevalence and risk factors of PTSD and its comorbidity with personality disorder. SETTING: General practice centre in Valencia (Spain). METHOD: Patients who had experienced at least one traumatic event in their lives were selected from a random sample attending a primary healthcare centre in Valencia and blindly assessed by trained professionals. Patients suffering from PTSD were compared with those who were not. PTSD and personality disorder diagnoses were established using CIDI and SCID-II interviews respectively. Sex, age at the time of experiencing trauma, frequency, multiplicity and type of trauma, dissociative symptoms, personality disorder and severity of PTSD were subjected to multivariate analysis to estimate the probability of developing PTSD and its duration. RESULTS: Life prevalence rate was 14% and current prevalence 9%. Dissociative symptoms and personality disorder were significantly associated with PTSD. Cluster analysis based on age, frequency and type of trauma revealed the existence of one subgroup composed mainly of women who had experienced frequent body-contact trauma at an early age, developed severe PTSD and suffer from a variety of personality disorders, particularly paranoid personality disorder. Time to the complete disappearance of symptoms was only explained by the initial severity of PTSD. CONCLUSION: PTSD is a frequent disorder in general practice and it is often associated with personality disorder. Women who experienced high frequency body-contact traumatic events at an early age often suffer from personality disorder and present a particularly severe form of PTSD deserving referral to specialised care.

Comparative validity of MMPI-2 and MCMI-II personality disorder classifications.

Minnesota Multiphasic Personality Inventory-2 (MMPI-2) overlapping and nonoverlapping scales were demonstrated to perform comparably to their original MMPI forms. They were then evaluated for convergent and discriminant validity with the Million Clinical Multiaxial Inventory-II (MCMI-II) personality disorder scales. The MMPI-2 and MCMI-II personality disorder scales demonstrated convergent and discriminant coefficients similar to their original forms. However, the MMPI-2 personality scales classified significantly more of the sample as Dramatic, whereas the MCMI-II diagnosed more of the sample as Anxious. Furthermore, single-scale and 2-point code type classification rates were quite low, indicating that at the level of the individual, the personality disorder scales are not measuring comparable constructs. Hence, each instrument is providing similar and unique information, justifying their continued use together for the purpose of diagnosing personality disorders.

Personality disorders in the community: results from the Australian National Survey of Mental Health and Well-being Part III. Relationships between specific type of personality disorder, Axis 1 mental disorders and physical conditions with disability and health consultations.

BACKGROUND: The aim of the present study was to examine in a national survey sample the risks of having a specific personality disorder (PD) and associations with gender, of having one or more physical conditions, of having one or more Axis 1 conditions, and of the severity (or degree) of disability. We also examined the association of specific PDs with having sought a consultation for health or mental health problems with a general practitioner (GP), a psychologist, or psychiatrist over the past 12 months. METHOD: Data were derived from the Australian National Mental Health and Well-Being Survey, conducted between May and August 1997. A stratified random sample of households was generated, from which all persons aged 18 or over were considered potential interviewees. There were 10,641 survey respondents, this representing a response rate of 78%. Each interviewee was asked 59 questions indexing specific ICD-10 PD criteria. RESULTS: Logistic regressions identified that some specific PDs, especially borderline PD, were more strongly associated with having one or more Axis I conditions, greater mental disability and lost days of total and partial role functioning than having No PD, and that others, notably anankastic PD, were less likely to be associated with the same variables. Some specific PDs, again most notably borderline PD, were more associated than others, again most notably anankastic PD, with having sought mental health consultations from GPs, psychiatrists, and psychologists. By contrast, PD associations with gender, physical conditions, physical disability and health consultations with the three professional groups were weaker as reflected in the comparatively smaller odds ratios and were also less consistent than the pattern with the previously mentioned variables. CONCLUSION: The study reports findings from a nationwide survey and, as such, the data are less influenced by the selection and setting bias found in most other studies investigating these variables. The findings of the study do point to some specific PDs, such as borderline PD, being associated with greater Axis 1 psychopathology, disability and mental health consultations than others, such as anankastic PD. It appears that although anankastic PD in itself is associated with more disability than having No PD, it becomes significantly more disabling when it is associated with other comorbid PDs.

[Effectiveness of outpatient treatment for alcoholism - impact of personality disorders on course of treatment].

Personality disorders (PS) frequently exist as comorbid disorder in alcoholism. However, the impact of comorbid personality disorder on the treatment and course of alcoholism still remains unclear. On that background, the present study on the efficacy of an intensive out-patient therapy for alcohol-dependents investigated the influence of comorbid personality disorder on the relapse and dropout rate during the treatment phase in 102 patients. Personality disorders were assessed with the SCID-II (DSM-IV). On a descriptive level results indicate that comorbidity with negativistic personality disorder and Cluster B PS may adversely affect the course of treatment. Statistical analyses, however, revealed that the observed differences in the type or number of personality disorders between patients with or without relapse resp. between patients with or without dropout failed to reach statistical significance. Thus, we conclude that the relevance of comorbid personality disorder on the course of alcoholism may be overestimated. The present results indicate that patients with comorbid personality disorder can be successfully integrated into a high-structured outpatient therapy.

Social problem-solving abilities and personality disorder characteristics among dual-diagnosed persons in substance abuse treatment.

We examined the relation of self-appraised social problem-solving abilities and personality-disorder characteristics to the adjustment and compliance of persons with dual diagnoses in substance-abuse treatment. It was hypothesized that elements of the problem-orientation component would remain predictive of depressive behavior and distress after considering personality-disorder characteristics among 117 persons receiving inpatient-substance-abuse treatment. Furthermore, self-appraised problem-solving abilities were expected to predict the occurrence of "dirty" drug and alcohol screens during treatment and compliance with the first scheduled community follow-up visit. Results supported predictions concerning the relation of problem-solving confidence to depressive behavior, distress, and substance-use screens; however, a paradoxical relation was observed between the problem-orientation variables and compliance with the first outpatient visit. The results are interpreted within the context of contemporary models of social problem solving and the implications for cognitive-behavioral assessment and intervention are considered.

Functioning styles of personality disorders and five-factor normal personality traits: a correlation study in Chinese students.

BACKGROUND: Previous studies show that both the categorical and dimensional descriptors of personality disorders are correlated with normal personality traits. Recently, a 92-item inventory, the Parker Personality Measure (PERM) was designed as a more efficient and precise first-level assessment of personality disorders. Whether the PERM constructs are correlated with those of the five-factor models of personality needs to be clarified. METHODS: We therefore invited 913 students from poly-technical schools and colleges in China to answer the PERM, the Five-Factor Nonverbal Personality Questionnaire (FFNPQ), and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). RESULTS: Most personality constructs had satisfactory internal alphas. PERM constructs were loaded with FFNPQ and ZKPQ traits clearly on four factors, which can be labelled as Dissocial, Emotional Dysregulation, Inhibition and Compulsivity, as reported previously. FFNPQ Openness to Experience, Conscientiousness and Extraversion formed another Factor, named Experience Hunting, which was not clearly covered by PERM or ZKPQ. CONCLUSION: The PERM constructs were loaded in a predictable way on the disordered super-traits, suggesting the PERM might offer assistance measuring personality function in clinical practice.

The relationship between defense styles and personality disorders.

The relationships between personality disorder clusters and defense mechanism factors were evaluated in 31 female and 24 male psychiatric inpatients from an urban hospital, who ranged in age from 19 to 57 years. The degree to which defense factors predicted personality disorder psychopathology was assessed, with gender entered as a covariate. The degree of borderline psychopathology had the strongest relationship with the Immature defense style (F(1,54) = 9.83, R2 = .54, p < .05). The results support previous research demonstrating a stronger link between Borderline personality disorder and defense styles relative to other personality disorders.

Influence of personality disorder on the treatment of panic disorder--comparison study.

UNLABELLED: Most clinicians tend to believe that the occurrence of the anxiety disorder in comorbidity with a personality disorder often leads to longer treatment, worsens the prognosis, and thus increasing treatment costs. The study is designed to compare the short-term effectiveness of combination of cognitive behavioral therapy and pharmacotherapy in patient suffering with panic disorder with and without personality disorder. METHOD: We compare the efficacy of 6th week therapeutic program and 6th week follow up in patients suffering with panic disorder and/or agoraphobia and comorbid personality disorder (29 patients) and panic disorder and/or agoraphobia without comorbid personality disorder (31 patients). Diagnosis was done according to the ICD-10 research diagnostic criteria confirmed with MINI and support with psychological methods: IPDE, MCMI-III and TCI. Patients were treated with CBT and psychopharmacs. They were regularly assessed in week 0, 2, 4, 6 and 12 by an independent reviewer on the CGI (Clinical Global Improvement) for severity and change, PDSS (Panic Disorder Severity Scale), HAMA (Hamilton Anxiety Rating Scale), SDS (Sheehan Disability Scale), HDRS (Hamilton Depression Rating Scale), and in self-assessments BAI (Beck Anxiety Inventory) and BDI (Beck Depression Inventory). RESULTS: A combination of CBT and pharmacotherapy proved to be the effective treatment of patients suffering with panic disorder and/or agoraphobia with or without comorbid personality disorder. The 12th week treatment efficacy in the patients with panic disorder without personality disorder had been showed significantly better compared with the group with panic disorder comorbid with personality disorder in CGI and specific inventory for panic disorder--PDSS. Also the scores in depression inventories HDRS and BDI showed significantly higher decrease during the treatment comparing with group without personality disorder. But the treatment effect between groups did not differ in objective anxiety scale HAMA, and subjective anxiety scale BAI.

Axis I psychiatric symptoms associated with HIV infection and personality disorder.

OBJECTIVE: The prevalences of personality disorders among HIV-positive and HIV-negative homosexual men were compared, and the presence of personality disorders was related to axis I psychiatric disorders, psychiatric distress, and impaired functioning. METHOD: The subjects were 162 homosexual men who either were HIV seronegative (N = 52) or were seropositive and had absent to moderate physical symptoms (N = 110). Lifetime and current histories of DSM-III-R axis I disorders, current diagnoses of DSM-III-R personality disorders, and levels of anxiety, depression, hopelessness, and adaptive functioning were assessed. RESULTS: In both the seropositive and seronegative groups, 19% of the study participants were diagnosed with personality disorders. The seropositive participants with personality disorders reported higher levels of psychiatric symptoms and poorer functioning than all participants without personality disorders, and they were over six times as likely as the seronegative participants without personality disorders to have current axis I disorders. CONCLUSIONS: These findings indicate that HIV infection and personality disorders may interactively increase the likelihood of clinically significant psychiatric symptoms.

Medication utilization patterns and methods of suicidality in borderline personality disorder.

BACKGROUND: Borderline personality disorder (BPD) is a psychiatric disorder characterized by suicidal thoughts/attempts and instability of mood, interpersonal relationships, and self-image. Patients with BPD engage in manipulative acts in apparent attempts to exert control in their interpersonal relationships. This issue of control may also be exhibited in their manner of self-medication. OBJECTIVE: To examine the medication utilization patterns of patients with BPD versus patients without personality disorders in a control group and to compare methods of suicidality between the groups. METHODS: A randomized, retrospective, chart review study was conducted at an academic medical center psychiatric hospital. The study examined the medication utilization patterns and methods of suicidality displayed over a one-year period for 29 patients hospitalized with BPD versus 29 patients in a control group. RESULTS: The number of psychotropic, non-psychotropic, and total drugs on admission and discharge was significantly greater for patients with BPD compared with patients in the control group. There was no significant difference between the 2 groups with respect to overdose and cutting methods of suicidality. The mean number of Axis III discharge diagnoses in the control group upon discharge was significantly less than that in the study group. Approximately 25% of patients with BPD considered overdosage as a means to end their life. CONCLUSIONS: As patients with BPD receive more medications than patients without the disorder and often exhibit suicidal thoughts/attempts, clinicians should closely monitor the use of all medications.
