Treatment outcome was compared for three groups of patients in a chemical dependency unit--14 patients with personality disorder, 16 patients with traits of personality disorder, and 34 patients with no personality disorder. Patients with personality disorder were as likely as other patients to complete the 4-month aftercare program and to maintain abstinence while in the aftercare program.
The purpose of this study was to investigate the frequency of DSM-III-R personality disorders in depressed patients treated in primary care, and to examine the effect of sertraline or citalopram on the diagnosis of personality disorders. A total of 308 patients with a major depressive disorder were assessed with the Swedish version of the Structured Clinical Interview for Personality Disorders (SCID) screen questionnaire, before and after 24 weeks double-blind treatment with sertraline (50-150 mg/day) or citalopram (20-60 mg/day). Following treatment, significant reductions in the frequency of paranoid, borderline, avoidant and dependent personality disorder diagnoses were seen in both treatment groups. When the personality disorders were analysed as continuous, dimensional personality traits significant reductions were seen for most personality categories. To elucidate if the observed reductions in personality disorder criteria could be explained by the improvement in depressive symptomatology, a series of multiple regressions were made. Reduction of depression scores was of some importance for the changes in most personality disorders. However, the multiple R never exceeded 0.24 (cluster C). Type of drug was of importance only as concerns obsessive-compulsive personality disorder. Overall, the results suggest that sertraline and citalopram may be beneficial in the treatment of certain personality disorder traits in patients with major depressive disorders.
The authors compared 18 patients diagnosed as having borderline personality disorder with 102 patients with orther diagnoses in a psychiatric emergency service. They found that 81 of 129 items obtained from the literature on borderline personality disorder were significantly more characteristic of the patients diagnosed as borderline than patients with other diagnoses. When these items were included in a Borderline Personality Scale they significantly distinguished patients diagnosed as borderline from those with other diagnoses. The patients diagnosed as borderline were not psychotic but were angry, demanding, and difficult to interview; specific histories, interpersonal relationships, defenses, and other judgments of personality functioning were also prominent characteristics of these patients. On the basis of these findings and other studies, the authors maintain that the patients diagnosed as borderline actually had a borderline personality disorder.
The multiaxial nature of DSM-III has stimulated interest in the personality disorders. There are also indications that it has produced an increase in their diagnosis. However, there is clinical and psychometric evidence that a personality evaluation undertaken while a patient is in a dysphoric mental state may distort or misrepresent traits, the so-called trait-state problem in personality assessment. The present study appears to be the first to investigate this phenomenon with a clinical interview rather than with personality tests. It examined the effect of anxiety, depression, and level of global impairment on the diagnosis of personality disorder and the assessment of the criteria for the individual Axis II disorders. Eighty-four patients, most of whom had current Axis I diagnoses, were evaluated by seven experienced clinicians with a new semistructured interview, the Personality Disorder Examination. The sample evidenced a trend toward acknowledging fewer maladaptive personality traits at follow-up than at entry. There was no evidence, however, that anxiety or depression had affected either the diagnosis of a personality disorder or the criteria associated with most of the individual personality disorders.
OBJECTIVE: This study investigated a previous claim that working memory may be 'particularly impaired' in adult attention-deficit/hyperactivity disorder (ADHD), compared with other psychiatric disorders which affect frontal lobe-mediated executive functions. METHOD: Performance on spatial working memory (SWM) and two additional tasks were investigated for adult patients selected on the basis of DSM-IV ADHD (n = 19), adult patients selected on the basis of borderline personality disorder (BPD) (n = 19), and non-clinical control subjects (n = 19). Groups were matched for age, verbal IQ and gender. RESULTS: Analysis of variance showed that the ADHD group had significant impairment of SWM performance relative to the non-clinical controls. Although there was a trend towards impairment in the BPD group relative to non-clinical controls, this did not reach significance. CONCLUSION: The results are consistent with the claim that aspects of working memory are 'particularly impaired' in adult ADHD. Also, the BPD group had a longer deliberation time for one of the additional tasks, compared with the ADHD group, which indicated that the patient groups may have different patterns of neuropsychological impairments.
OBJECTIVE: The authors' goal was to test empirically a commonly held assumption that the depression in borderline personality disorder is primarily anaclitic. METHOD: The Depressive Experiences Questionnaire and the Hamilton Rating Scale for Depression were administered to 26 patients with borderline personality disorder (16 of whom were depressed) and 12 depressed patients without borderline personality disorder. RESULTS: Patients with borderline personality disorder showed more self-criticism but did not endorse more anaclitic items than depressed patients without borderline personality disorder. CONCLUSIONS: These findings suggest that self-criticism is an underemphasized characteristic of depression in borderline personality disorder.
Many patients with a diagnosis of borderline personality disorder describe multi-modal hallucinations. A likely cortical origin for multi-modal hallucinations is the inferior parietal lobule. Neuropsychological testing of borderline personality disorder reveals deficits of visuospatial capacity; a function which is also localised to the inferior parietal lobule. It is hypothesised that this brain area is likely to be dysfunctional in those patients with borderline personality disorder who have multi-modal hallucinations. A deficit in the inferior parietal lobe could plausibly explain a number of other clinical features; the gender dimorphism of this disorder, the lack of expressive gesture and the specific response to clozapine. More speculatively; the increased concern over this disorder over the past 40 years could result from the normal population showing an increase in functional ability in the parietal lobe, leaving patients with parietal deficits relatively more disabled.
This study examines the relationship between borderline personality disorder (BPD) and the use of psychiatric services in a naturalistic follow-up comparison with antisocial personality disorder and bipolar type II affective disorder. In the first follow-up series, borderline psychopathology was associated with higher levels of psychiatric service use (emergency, daycare, and inpatient). Markov analyses indicated that the transition between levels of psychiatric service use followed a stationary, second order process (i.e. the immediate past and current service use, predicted use on the next follow-up, and the relationship did not depend on the point in time examined in the follow-up series). Further, the transition probabilities generated from this model did not depend significantly on diagnosis. Predictions from the Markov model about the cumulative probability that subjects would use the highest level of psychiatric services were tested on a second series of follow-ups on the same subjects 20 months later. The model-based predictions (starting from the observed levels in the first two follow-ups of the second series) clustered into three groups, of high, middle, and low predicted probabilities. The subject group with the lowest predicted likelihood had a cumulative probability of 0.19 for using emergency, daycare, or inpatient hospitalization by 22 months of follow-up, whereas the group with the highest likelihood (containing a disproportionate number of BPD subjects) had a cumulative observed probability of 0.80. The Markov model generated from this second series supported the stationarity of the transition process. BPD subjects began using high levels of psychiatric services, but their transition from one level to another over time followed a process similar to that of non-BPD subjects.
OBJECTIVE: The present study investigates the comorbidity between bulimia nervosa (BN) and the entire range of American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, 3rd rev. ed. (DSM-III-R) personality disorders and controls for the presence of coexisting depression. METHOD: The Personality Disorders Examination (PDE), a structured interview that encompasses all 13 (provisional) DSM-III-R personality disorders, was administered to three groups of subjects: depressed BN patients (n = 15), nondepressed BN patients (n = 15), and nonpsychiatric controls (n = 15). The BN patients were referrals to a dieting disorder unit affiliated with the University of Sydney. They all met DSM-III-R criteria and all had body mass indexes (BMIs) greater than 19. The nonpsychiatric control group were recruited from an undergraduate psychology course. All subjects were given the Bulimic Investigatory Test, Edinburgh (BITE), the Eating Disorders Inventory-2 (EDI-2), the Hamilton Depression Rating Scale (HDRS), and the PDE. RESULTS: 46.7% of depressed BN patients met the criteria for at least one Axis II diagnosis, as assessed by the PDE, and 33.3% of nondepressed BN patients received such a diagnosis, whereas only 6.7% of nonpsychiatric control subjects met this criterion (p < .05). The results of the present study provide support for an increased comorbidity between personality disorders and BN that cannot be attributed to the confounding influence of coexisting depression. DISCUSSION: This finding enables the identification of subgroups of individuals with BN, enabling them to be compared and contrasted. The identification of differences between subgroups may provide information regarding prognosis and differential response to treatment, which could enable more appropriate treatment decisions to be made.
Similarity relationships between personality factors and personality disorders (PDs) are usually described within the conceptual framework of the "big five" model. Recently, two-dimensional circumplex models have been suggested as alternatives, such as the interpersonal circle, the multifacet circumplex, and the circumplex of premorbid personality types. The present study is an empirical investigation of the similarity relationships between the big five, the 11 DSM-III-R personality disorders and four subaffective disorders. This was performed in a sample of 165 psychiatric inpatients. We tested the extent to which the relationships could be adequately represented in two dimensions and which circumplex model can be supported by the empirical configuration. Results obtained by principal-components analysis (PCA) strongly confirm the circumplex of premorbid personality, and to some extent the multifacet circumplex. However, the interpersonal circle cannot be confirmed.
The author determined the sex distribution of 170 outpatients with a DSM-III diagnosis of personality disorder measured by standardized instruments and compared his findings with DSM-III predictions. They confirmed the prediction of more women diagnosed as having histrionic personality disorder and more men diagnosed as having paranoid, compulsive, and antisocial personality disorders. The predicted excess of women diagnosed as having borderline and dependent personality disorders was not confirmed.
Previous reports have stressed the implication of Personality Disorders as predictors of a poorer treatment outcome in Obsessive-Compulsive Disorder (OCD). The aim of this study was to see whether or not Obsessive-Compulsive Personality Disorder in Obsessive-Compulsive Disorder may be predictive for a poorer outcome to antiobsessive pro-serotonergic pharmacological treatment. For this purpose, 30 OCD patients were divided into two groups according to the presence or absence of Obsessive-Compulsive Personality Disorder. Ten-week standardized treatments with oral SRI drugs were given to look for different outcomes between the two groups in Obsessive-Compulsive symptom severity. At the end of the study we found that the presence of Obsessive-Compulsive Personality Disorder, along with the total number of Personality Disorders, did predict poorer response to pharmacological treatment in OCD.
BACKGROUND: Little is known about the long-term outcome of personality disorder traits. The purpose of this study was to investigate, in a community-residing population, the longitudinal relationship between psychiatrist-assessed personality disorder scores and global functioning 13-18 years later. METHOD: A stratified random sample of residents of east Baltimore were examined by psychiatrists in 1981 and asssessed for DSM-III personality disorders using a semi-structured instrument, the Standardized Psychiatric Examination. A total of 292 persons were re-examined by different psychiatrists during 1994-1999 using the Schedules for the Assessment of Neuropsychiatry (SCAN). After completion of the SCAN, the subjects' functional status was evaluated using the Global Assessment of Functioning (GAF). The relationships between personality dimensions and follow-up GAF scores were evaluated using linear regression models. RESULTS: All of the personality disorder scales measured in 1981 were inversely related to functioning 13-18 years later, with the exception of narcissistic and compulsive scales. After controlling for Axis I disorders diagnosed contemporaneously with GAF assessment, schizoid, antisocial, borderline, histrionic, and avoidant personality disorder scores significantly predicted GAF scores. CONCLUSIONS: Most dimensions of DSM-III personality disorder traits were significantly associated with global functioning after an interval of 15 years. However, only schizoid, antisocial, borderline, histrionic, and avoidant personality disorder traits had long-term effects on functioning when Axis I disorders at follow-up were controlled. This suggests that the functional effect of the other personality disorder traits may be mediated through their relationship with Axis I disorders. Future research is needed using more specific and sensitive outcome measures.
Both the interrater and test-retest-retest reliability of axis I and axis II disorders were assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). Fair-good median interrater kappa (.40-.75) were found for all axis II disorders diagnosed five times or more, except antisocial personality disorder (1.0). All of the test-retest kappa for axis II disorders, except for narcissistic personality disorder (1.0) and paranoid personality disorder (.39), were also found to be fair-good. Interrater and test-retest dimensional reliability figures for axis II were generally higher than those for their categorical counterparts; most were in the excellent range (> .75). In terms of axis I, excellent median interrater kappa were found for six of the 10 disorders diagnosed five times or more, whereas fair-good median interrater kappa were found for the other four axis I disorders. In general, test-retest reliability figures for axis I disorders were somewhat lower than the interrater reliability figures. Three test-retest kappa were in the excellent range, six were in the fair-good range, and one (for dysthymia) was in the poor range (.35). Taken together, the results of this study suggest that both axis I and axis II disorders can be diagnosed reliably when using appropriate semistructured interviews. They also suggest that the reliability of axis II disorders is roughly equivalent to that reliability found for most axis I disorders.
BACKGROUND: There is a need for a brief and simple screen for personality disorders that can be used in routine psychiatric assessments. AIMS: To test the concurrent validity and test-retest reliability of a brief screen for personality disorder. METHOD: Sixty psychiatric patients were administered a brief screening interview for personality disorder. On the same day, they were interviewed with an established assessment for DSM-IV personality disorder. Three weeks later, the brief screening interview was repeated in order to examine test-retest reliability. RESULTS: A score of 3 on the screening interview correctly identified the presence of DSM-IV personality disorder in 90% of participants. The sensitivity and specificity were were 0.94 and and 0.85 respectively. CONCLUSIONS: The study provides preliminary evidence of the usefulness of the screen in routine clinical settings.
The relationship between the five-factor model (FFM) of personality and the Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; DSM-III-R) personality disorders was examined in a sample of 54 psychiatric outpatients. Correlations between raw scores on the NEO-Personality Inventory (NEO-PI) and the number of DSM-III-R personality disorder symptoms rated present using a semistructured interview were computed. In addition, correlations between NEO-PI scores and scores on two self-report personality disorder inventories were also examined to determine which results replicated across instruments. Results indicated that the FFM personality dimensions of Neuroticism, Extraversion, and Agreeableness were most apparent in the DSM-III-R conceptualizations of the personality disorders.
OBJECTIVE: The authors sought to determine the frequency of DSM-III personality disorders in subjects with obsessive-compulsive disorder, well comparison subjects, and their first-degree relatives. METHOD: Thirty-two subjects with obsessive-compulsive disorder and 33 age-(within 5 years) and gender-matched well comparison subjects were assessed with the Structured Interview for DSM-III Personality Disorder and several self-report instruments. Their first-degree relatives were assessed in a blind manner with the same instruments. RESULTS: Subjects with obsessive-compulsive disorder were more likely than well comparison subjects to have a personality disorder, but compulsive personality was not the most frequent. No significant differences were found in the prevalence of personality disorders among first-degree relatives, including compulsive personality, or in obsessional, hysterical, or oral character traits. CONCLUSIONS: Personality disorders are highly prevalent among patients with obsessive-compulsive disorder, but the data do not support a relationship between obsessive-compulsive disorder and compulsive personality.
MMPI, MBHI, and MCMI personality disorder scales were analyzed for convergent and discriminant validity. Friedman's ANOVA indicated that there were no significant differences among the sample's averaged scale scores. Further analyses of these data, however, demonstrated that the Millon instruments classified significantly more of the sample as personality disordered when compared to Morey's MMPI personality disorder scales. In addition, codetype correspondence among the three instruments was only 4 to 6%. When the instruments were analyzed in a pair-wise fashion, codetype correspondence increased to approximately 10 to 20%. These data indicate that these personality disorder scales do not demonstrate construct equivalence, particularly at the level of the individual profile.
