Characterizing affective instability in borderline personality disorder.

OBJECTIVE: This study sought to understand affective instability among patients with borderline personality disorder by examining the degree of instability in six affective domains. The authors also examined the subjective intensity with which moods are experienced and the association between instability and intensity of affect. METHOD: In a group of 152 patients with personality disorders, subjective affective intensity and six dimensions of affective instability were measured. The mean scores for lability and intensity for each affective domain for patients with borderline personality disorder were compared with those of patients with other personality disorders through analyses that controlled for other axis I affective disorders, age, and sex. RESULTS: Greater lability in terms of anger and anxiety and oscillation between depression and anxiety, but not in terms of oscillation between depression and elation, was associated with borderline personality disorder. Contrary to expectation, the experience of an increase in subjective affective intensity was not more prominent in patients with borderline personality disorder than in those with other personality disorders. CONCLUSIONS: By applying a finer-grained perspective on affective instability than those of previous personality disorder studies, this study points to patterns of affective experience characteristic of patients with borderline personality disorder.

The comorbidity of alcoholism and personality disorders in a clinical population: prevalence rates and relation to alcohol typology variables.

This study assessed prevalence rates and overlap among Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised; DSM-III-R; American Psychiatric Association, 1987) personality disorders in a multisite sample of 366 substance abusers in treatment. In addition, the relation of antisocial personality disorder (APD), borderline personality disorder (BPD), and paranoid personality disorder (PPD) to alcohol typology variables was examined. Structured diagnostic interviews and other measures were administered to participants at least 14 days after entry into treatment. Results indicated high prevalence rates for APD and non-APD disorders. There was extensive overlap between Axis I disorders and personality disorders, and among personality disorders themselves. APD, BPD, and PPD were linked to more severe symptomatology of alcoholism and other clinical problems. However, only APD and BPD satisfied subtyping criteria, after controlling for other comorbidity. Implications for classifying alcoholics by comorbid disorders are discussed.

Validity of self-defeating personality disorder.

OBJECTIVE: The purpose of this study was to assess the validity of DSM-III-R self-defeating personality disorder. METHOD: Applicants for inpatient treatment of personality disorders (N = 100) or psychoanalysis (N = 100) were independently evaluated face to face by experienced clinicians using the Structured Clinical Interview for DSM-III-R and the Personality Disorder Examination. Internal consistency; agreement between assessments; diagnostic efficiency of criteria; prevalence; sex ratio; comorbidity with axis I and II disorders; and relationship to education, current employment, and selection for psychoanalytically oriented treatment were examined. RESULTS: The internal consistency of the criteria set and the agreement between psychiatric assessments of self-defeating personality disorder were fair. The most discriminating criteria were those referring to a) choices leading to disappointment, failure, or mistreatment and b) rejection of opportunities for pleasure. A consensus diagnosis of self-defeating personality disorder was more common than all but three other axis II disorders. The sex ratio of the subjects with this diagnosis was not significantly different from the sex ratio of the entire subject group or of patients with other personality disorders. Significant comorbidity with borderline and dependent personality disorders and with current mood disorders was found. Patients with self-defeating personality disorder resembled patients with other personality disorders in educational attainment and treatment assignment. They were more likely to be employed. CONCLUSIONS: These data lend little support to the validity of self-defeating personality disorder as a separate personality disorder category.

What are the borders of borderline personality disorder?

It is argued that the usefulness of borderline personality disorder in clinical and research practice is largely because the borders of the diagnosis are so flexible. The diagnosis overlaps with other personality disorders, disturbances of mood and intermittent abnormal behavior. As almost all behavior likely to lead to consultation with mental health professionals is included among the elements of personality disorder, it is not surprising that it is almost the most common condition seen by specialists in the field. An attempt is made to define the borders of the condition in this review. It is concluded that these are so far-reaching that they negate the notion that borderline conditions are personality disorders. It is argued that the borderline state is a coaxial diagnosis of personality and mental state disorder and to continue to describe the concept as a personality disorder is wrong and misleading.

Prevalence, correlates, and disability of personality disorders in the United States: results from the national epidemiologic survey on alcohol and related conditions.

OBJECTIVE: To present nationally representative data on the prevalence, sociodemographic correlates, and disability of 7 of the 10 DSM-IV personality disorders. METHOD: The data were derived from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (N = 43,093). Diagnoses were made using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version, and associations between personality disorders and sociodemographic correlates were determined. The relationship between personality disorders and 3 emotional disability scores (Short-Form 12, version 2) was also examined. RESULTS: Overall, 14.79% of adult Americans (95% CI = 14.08 to 15.50), or 30.8 million, had at least 1 personality disorder. The most prevalent personality disorder in the general population was obsessive-compulsive personality disorder, 7.88% (95% CI = 7.43 to 8.33), followed by paranoid personality disorder 4.41% (95% CI = 4.12 to 4.70), antisocial personality disorder 3.63% (95% CI = 3.34 to 3.92), schizoid personality disorder 3.13% (95% CI = 2.89 to 3.37), avoidant personality disorder 2.36% (95% CI = 2.14 to 2.58), histrionic personality disorder 1.84% (95% CI = 1.66 to 2.02), and dependent personality disorder 0.49% (95% CI = 0.40 to 0.58). The risk of avoidant, dependent, and paranoid personality disorders was significantly greater among women than men (p <.05); the risk of antisocial personality disorder was greater among men compared with women (p <.05); and no sex differences were observed in the risk of obsessive-compulsive, schizoid, or histrionic personality disorders. In general, risk factors for personality disorders included being Native American or black, being a young adult, having low socioeconomic status, and being divorced, separated, widowed, or never married. Avoidant, dependent, schizoid, paranoid, and antisocial personality disorders (p <.02 to p <.0001) were each statistically significant predictors of disability. Obsessive-compulsive personality disorder was inconsistently related to disability. In contrast, disability was not significantly different among individuals with histrionic personality disorder compared with those without the disorder. CONCLUSION: Personality disorders are prevalent in the general population and are generally highly associated with disability. This study highlights the need to develop more effective and targeted prevention and intervention initiatives for personality disorders.

Relations of five-factor model antagonism facets with personality disorder symptomatology.

The Five-Factor Model of Personality (FFM) has been used to conceptualize personality disorders as maladaptive variants of normal personality traits. This study assessed the convergence of 6 lower order traits, or facets, of FFM agreeableness versus antagonism (trust, straightforwardness, altruism, compliance, modesty, and tender-mindedness) with antisocial, borderline, narcissistic, paranoid, and passive-aggressive personality traits. Interview-based scores for all of the antagonism facets except compliance demonstrated the expected relations with these personality disorder traits. Results for self-reported facet scores were less clearly supportive, only yielding convergence for straightforwardness and altruism with respect to antisocial traits. It is suggested that future investigations of the FFM, or other normal personality trait models, and personality disorder symptomatology include analyses at the lower order trait level.

Disordered personality style: higher rates in non-melancholic compared to melancholic depression.

OBJECTIVE: We test whether there is differential representation of disordered personality function across melancholic and non-melancholic depressive sub-types, with levels of differentiation examined against differing sub-typing measures. METHOD: In a sample of 245 subjects meeting criteria for a non-psychotic major depressive episode lasting less than 2 years, we examine for differential rates of disordered personality style across melancholic and non-melancholic depression, using four differing sub-typing measures (i.e., DSM-III-R and DSM-IV criteria, Newcastle Index, and the CORE measure). Disordered personality was assessed by psychiatrist ratings of 15 differing personality styles underpinning disorder classes, and several parameters and domains that reflect the arenas whereby disordered personality may be manifested. RESULTS: However defined, those with non-melancholic depression were distinctly more likely to rate as showing disordered personality function, with over-representation to an avoidant personality disorder style being the most consistently and strongly identified personality disorder class. Because of limitations to several of the sub-typing measures, we focus on the DSM-IV system. Discriminant function analyses indicated that those so identified as having non-melancholic depression were significantly more likely to rate as having avoidant and schizoid personality styles. A principal components analysis of our 15 differing personality disorder classes identified three molar classes corresponding to the three-cluster DSM system. Again, non-melancholic (compared to melancholic) subjects were more likely to return higher scores: in order, an 'anxious and fearful' (Cluster C) personality style, then an 'eccentric' Cluster A, and somewhat less clearly, a 'dramatic' Cluster B personality disorder style. Specificity to the non-melancholic depressive class was again suggested in relation to a large number of the parameters and domains measuring disordered personality function. CONCLUSIONS: Disordered personality function appears distinctly more likely in non-melancholic, compared to melancholic depression.

Prevalence and correlates of personality disorders in a community sample.

BACKGROUND: Knowledge of the prevalence and correlates of personality disorders in the community is important for identifying treatment needs and for provision of psychiatric services. AIMS: To estimate the prevalence of personality disorders in a community sample and to identify demographic subgroups with especially high prevalence. METHOD: Clinical psychologists used the International Personality Disorder Examination to assess DSM-IV and ICD-10 personality disorders in a sample of 742 subjects, ages 34-94 years, residing in Baltimore, Maryland. Logistic regression was used to evaluate the association between demographic characteristics and DSM-IV personality disorder clusters. RESULTS: The estimated overall prevalence of DSM-IV personality disorders was 9%. Cluster A disorders were most prevalent in men who had never married. Cluster B disorders were most prevalent in young men without a high school degree, and cluster C disorders in high school graduates who had never married. CONCLUSIONS: Approximately 9% of this community sample has a DSM-IV personality disorder. Personality disorders are over-represented in certain demographic subgroups of the community.

Longitudinal comparison of depressive personality disorder and dysthymic disorder.

BACKGROUND: Few studies have compared the related diagnostic constructs of depressive personality disorder (DPD) and dysthymic disorder (DD). The authors attempted to replicate findings of Klein and Shih in longitudinally followed patients with personality disorder or major depressive disorder (MDD) in the Collaborative Longitudinal Personality Disorders Study. METHODS: Subjects (N = 665) were evaluated at baseline and over 2 years (n = 546) by reliably trained clinical interviewers using semistructured interviews and self-report personality questionnaires. RESULTS: Only 44 subjects (24.6% of 179 DPD and 49.4% of 89 early-onset dysthymic subjects) met criteria for both disorders at baseline. Depressive personality disorder was associated with increased comorbidity of some axis I anxiety disorders and other axis II diagnoses, particularly avoidant (71.5%) and borderline (55.9%) personality disorders. Depressive personality disorder was associated with low positive and high negative affectivity on dimensional measures of temperament. Depressive personality disorder subjects had lower likelihood of remission of baseline MDD at 2-year follow-up, whereas DD subjects did not. The DPD diagnosis appeared unstable over 2 years of follow-up, as only 31% (n = 47) of 154 subjects who had DPD at baseline and also had follow-up assessment met criteria on blind retesting. LIMITATIONS: Results from this sample may not generalize to other populations. CONCLUSIONS: Depressive personality disorder and dysthymic disorder appear to be related but differ in diagnostic constructs. Its moderating effect on MDD and predicted relationship to measures of temperament support the validity of DPD, but its diagnostic instability raises questions about its course, utility, and measurement.

Recognizing comorbid personality disorder can help manage and treat the "untreatable".

Personality disorder is surprisingly prevalent. Clinical syndromes accompanied by personality disorder tend to be more severe, more treatment resistant, and more likely to recur than their counterparts. Learning to recognize personality disorder can enhance the efficacy of the clinician's management style and his or her ability to make appropriate plans for long-term psychotherapy. To assist diagnosis of personality disorder according to the DSM-IV, the authors present interpersonal descriptions and necessary and exclusionary conditions.

Abuse and neglect in childhood: relationship to personality disorder diagnoses.

BACKGROUND: Childhood history of abuse and neglect has been associated with personality disorders and has been observed in subjects with lifetime histories of suicidality and self-injury. Most of these findings have been generated from inpatient clinical samples. METHODS: This study evaluated self-rated indices of sustained childhood abuse and neglect in an outpatient sample of well-characterized personality disorder subjects (n=182) to determine the relative associations of childhood trauma indices to specific personality disorder diagnoses or clusters and to lifetime history of suicide attempts or gestures. Subjects met criteria for ~2.5 Axis II diagnoses and 24% reported past suicide attempts. The Childhood Trauma Questionnaire was administered to assess five dimensions of childhood trauma exposure (emotional, physical, and sexual abuse, and emotional and physical neglect). Logistic regression was employed to evaluate salient predictors among the trauma measures for each cluster, personality disorder, and history of attempted suicide and self-harm. All analyses controlled for gender distribution. RESULTS: Seventy-eight percent of subjects met dichotomous criteria for some form of childhood trauma; a majority reported emotional abuse and neglect. The dichotomized criterion for global trauma severity was predictive of cluster B, borderline, and antisocial personality disorder diagnoses. Trauma scores were positively associated with cluster A, negatively with cluster C, but were not significantly associated with cluster B diagnoses. Among the specific diagnoses comprising cluster A, paranoid disorder alone was predicted by sexual, physical, and emotional abuse. Within cluster B, only antisocial personality disorder showed significant associations with trauma scores, with specific prediction by sexual and physical abuse. For borderline personality disorder, there were gender interactions for individual predictors, with emotional abuse being the only significant trauma predictor, and only in men. History of suicide gestures was associated with emotional abuse in the entire sample and in women only; self-mutilatory behavior was associated with emotional abuse in men. CONCLUSION: These results suggest that childhood emotional abuse and neglect are broadly represented among personality disorders, and associated with indices of clinical severity among patients with borderline personality disorder. Childhood sexual and physical abuse are highlighted as predictors of both paranoid and antisocial personality disorders. These results help qualify prior observations of the association of childhood sexual abuse with borderline personality disorder.

The specificity of clinical characteristics in adults with attention-deficit/hyperactivity disorder: a comparison with patients with borderline personality disorder.

Characteristics of DSM-IV attention-deficit/hyperactivity disorder (ADHD) in adults can also be found as part of other psychiatric disorders. This study investigated the specificity of adult ADHD features in relation to patients with borderline personality disorder (BPD), a syndrome which shares some of its intrinsic features with ADHD and often co-occurs with ADHD. A group of 20 adult patients selected on the basis of a diagnosis of ADHD and 20 patients selected on the basis of a diagnosis of BPD were assessed by the self-report Attention Deficit Scales for Adults (ADSA). The two groups were matched for age, verbal IQ and gender. Of the nine ADSA scales, seven showed significant inter-group differences, in particular involving attention, organisation and persistence. The 'Consistency/Long-Term' scale, which mainly reflects impaired task and goal persistence, was the best discriminator between the groups. Furthermore, ratings on this scale correlated significantly with the error score of a computer-administered task of spatial working memory, the performance of which has been reported to be impaired in patients with ADHD. The results provide further validation for the ADSA scales and support a previous claim that 'long-term consistencies', i.e., related to task and goal persistence, is 'the centrepiece behavioural issue' for adults with ADHD.

Gender stereotypes for paranoid, antisocial, compulsive, dependent, and histrionic personality disorders.

To assess similarity between gender-role stereotypes and the personality disorder prototypes, university students (31 women and 13 men) were asked to assign gender to six descriptions of DSM-III--R personality disorders. Significant agreement was found in gender assignment for five of the six descriptions. Descriptions of the paranoid, antisocial, and compulsive personality disorders were viewed as male, and descriptions of the dependent and histrionic personality disorders were viewed as female. The description of schizoid personality disorder was not significantly gender-typed.

Treatment rejecting and treatment seeking personality disorders: Type R and Type S.

An important distinguishing feature of one group of personality disorders is the wish of the sufferer to seek treatment. For another group this wish is rarely entertained. Although there is some variation between different types of personality disorder the wish to change is not confined to any one diagnostic category. A useful subclassification of personality disorders is therefore into Type R (treatment rejecting) and Type S (treatment seeking) personality disorders, and these are defined operationally. The classification of 68 personality disordered patients on the caseload of an assertive community team using a simple scale showed a 3 to 1 ratio between Type R and Type S personality disorders with Cluster C personality disorders being significantly more likely to be Type S, and paranoid and schizoid (Cluster A) personality disorders significantly more likely to be Type R than others. It is suggested that this typology is useful for those contemplating treatment with those who have personality disorders.

Vomiting as a manifestation of borderline personality disorder in primary care.

BACKGROUND: Patients with borderline personality disorder often are found and treated in psychiatric settings following episodes of self-mutilation, such as wrist-slashing. Family physicians care for many patients with borderline personality disorder, but in primary care settings wrist-slashing or other physical mutilation is a less common presenting problem. Frequently these patients complain of such symptoms as nausea and vomiting that do not so obviously suggest psychopathology. METHODS: Three primary care patients with borderline personality disorder in whom episodic vomiting was the chief complaint are presented. Hypotheses from the literature about the neurobiology of vomiting and self-mutilation are discussed. RESULTS: Vomiting is a primary care analogue of self-mutilation in some patients with borderline personality disorder. CONCLUSIONS: Family physicians should include careful history taking to corroborate other features of borderline personality disorder in evaluating patients with persistent, episodic vomiting. Obtaining a history of early sexual abuse or chronic interpersonal problems as an adult should not only mitigate the compulsion for extensive, costly, and invasive gastrointestinal system evaluations in such patients, but also suggest more effective treatment strategies.

Patients with personality disorders: functional status, health care utilization, and satisfaction with care.

BACKGROUND: Personality disorders are believed to occur in approximately 10% of the adult population, yet they are rarely diagnosed in primary care settings. This study compares the functional status, health care utilization, and satisfaction with care for patients who were at high risk for a personality disorder with those who were at low risk. METHODS: Patients at high risk for personality disorders were identified using a standardized psychometric instrument, the Structured Clinical Inventory for DSM-III Axis II (SCID-II). After assigning patients to risk categories, responses were compared on the Medical Outcomes Study Short Form-36, the Beck Depression Inventory, the CAGE alcohol use questionnaire, and an adapted version of the RAND Patient Satisfaction Questionnaire. RESULTS: Patients who were at high risk for any personality disorder had lower functional status, higher risk for depression or alcohol abuse, and lower levels of satisfaction with care. These differences could not be explained by demographic or socioeconomic differences between high- and low-risk patients. Being at high risk for specific personality disorders, such as borderline, schizoid, and dependent disorders, was associated with higher degrees of functional impairment and greater risk for depression and alcohol abuse. Patients at high risk for other disorders, such as obsessive-compulsive, narcissitic, and schizotypal, consistently showed no appreciable degree of impairment as compared with patients at low risk for any personality disorder. Medical care utilization was no higher when personality disorders were examined in aggregate, but a marked increase in utilization was noted among patients at high risk for histrionic and dependent disorders. CONCLUSIONS: Among primary care patients, having a personality disorder is associated with lower functional status, lower satisfaction with health care, and higher risk for depression and alcohol abuse.

Rating of personality disorder features in popular movie characters.

BACKGROUND: Tools for training professionals in rating personality disorders are few. We present one such tool: rating of fictional persons. However, before ratings of fictional persons can be useful, we need to know whether raters get the same results, when rating fictional characters. METHOD: Psychology students at the University of Copenhagen (N = 8) rated four different movie characters from four movies based on three systems: Global rating scales representing each of the 10 personality disorders in the DSM-IV, a criterion list of all criteria for all DSM-IV personality disorders in random order, and the Ten Item Personality Inventory for rating the five-factor model. Agreement was estimated based on intraclass-correlation. RESULTS: Agreement for rating scales for personality disorders ranged from 0.04 to 0.54. For personality disorder features based on DSM-IV criteria, agreement ranged from 0.24 to 0.89, and agreement for the five-factor model ranged from 0.05 to 0.88. The largest multivariate effect was observed for criteria count followed by the TIPI, followed by rating scales. Raters experienced personality disorder criteria as the easiest, and global personality disorder scales as the most difficult, but with significant variation between movies. CONCLUSION: Psychology students with limited or no clinical experience can agree well on the personality traits of movie characters based on watching the movie. Rating movie characters may be a way to practice assessment of personality.

Gender differences in personality disorders.

OBJECTIVE: The aim of this study was to assess gender differences in personality disorders. Since heterogeneity of axis I diagnoses could introduce variability in the assessment of axis II diagnoses, the authors studied a group of patients with a primary diagnosis of major depression. METHOD: A total of 316 patients were evaluated with the Personality Diagnostic Questionnaire--Revised, a self-rating measure, or the Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II), a clinician-rated instrument, or both. Axis II disorders were assessed with the Personality Diagnostic Questionnaire--Revised for 288 patients with major depression. The SCID-II was administered to 117 subjects, with an additional 95 subjects receiving the SCID-II for cluster B diagnoses only. RESULTS: The mean 17-item Hamilton Depression Rating Scale scores for 108 men (mean age = 39.28 years) and 208 women (mean age = 39.11) were 19.0 (SD = 3.8) and 19.6 (SD = 6.9), respectively. Men were significantly more likely than women to meet criteria for narcissistic, antisocial, and obsessive-compulsive personality disorders as measured by the Personality Diagnostic Questionnaire--Revised and for narcissistic and obsessive-compulsive personality disorders as measured by the SCID-II. CONCLUSIONS: These findings are consistent with those of previous studies showing a greater prevalence of antisocial and narcissistic personality disorders in men. In contrast with other investigations, however, neither the Personality Diagnostic Questionnaire--Revised nor the SCID-II revealed a higher prevalence of any personality disorder in women.
