Personality and personality disorders among patients with major depression in combination with dysthymic or cyclothymic disorders.

Personality traits and personality disorders in 298 consecutive outpatients with pure major depression, major depression with dysthymic or cyclothymic disorder, pure dysthymic or cyclothymic disorder and other disorders were investigated. Patients with dysthymic or cyclothymic disorders alone or in combination with major depression showed more self-doubt, insecurity, sensitivity, compliance, rigidity and emotional instability. They were more schizoid, schizotypal, borderline and avoidant according to MCMI and had a higher prevalence of DSM-III Axis II diagnoses, and more borderline, avoidant, and passive-aggressive personality disorders, as measured by SIDP. All in all, dramatic and anxious clusters of personality disorders were more frequent among patients with dysthymic-cyclothymic disorders in addition to major depression than among patients with major depression only. The findings elucidated the close connection between the more chronic affective disorders and the personality disorders, irrespective of any concomitant diagnosis of major depression.

The aetiology, presentation and treatment of personality disorders.

Personality disorders are a heterogeneous collection of conditions with common features, which may include an exaggerated self-centred nature, little regard for the feelings of others, or the regular fabrication of stories to explain the behaviour of self or others. Whilst such features might be recognized as being present in many people at different times of their lives, it is the persisting nature and extremes of personality traits that distinguishes those who have personality disorders from those who do not. Apart from the problems that personality disorders bring on their own (such as dysfunctional relationships), when they coexist with mental disorders it makes the latter more difficult to treat. People with personality disorders are often depicted as being dangerous, yet only a few are and it is this minority group that attract public attention. Personality disorders are recognized as belonging to the group known as the serious mental illnesses, a group that mental health nurses are being encouraged to focus their attentions on, but it is accepted that there is a paucity of education and training in appropriate interventions for this group of people. This article provides an overview of the aetiology and presentation of personality disorders together with an examination of evidence-based therapeutic interventions.

Comorbidity of DSM-III-R eating disorders and personality disorders.

The purpose of this study was to assess the relationship of eating disorders to personality disorders. Two hundred subjects were independently administered the Structured Clinical Interview for DSM-III-R (SCID) and the Personality Disorder Examination (PDE) face-to-face by two experienced clinicians. One hundred forty-six also completed the Personality Diagnostic Questionnaire-Revised (PDQ-R). Rates of personality disorder among patients with and without eating disorders were determined by each of the three instruments. Comorbidity between bulimia nervosa and anorexia nervosa and a conservative estimate of individual Axis II disorders was examined. Eating disorders with and without personality disorders were compared on age at onset and two measures of illness severity. Results indicate that the association, in general, between personality disorders and eating disorders varies by diagnostic method. Bulimia nervosa, however, is associated with borderline personality disorder and anorexia nervosa with avoidant personality disorder. Eating disorders with personality disorders are characterized by chronicity and low levels of functioning compared with eating disorders without personality disorders.

Personality disorders.

Personality disorders are characterized by inflexible maladaptive traits that cause significant impairment in social and occupational functioning. Categories of personality disorders include paranoid, schizoid, histrionic, narcissistic, antisocial, borderline, avoidant, dependent, compulsive and passive-aggressive. The inflexible nature of these disorders and the lack of an alternative behavioral repertoire result in an inability to cope with environmental pressure. The goal of management is the development of healthier behavioral responses to stress. A personality change in older patients suggests organic disease.

Conduct disorder and personality disorders in hospitalized adolescents.

BACKGROUND: The purpose of this study was to investigate the differences between DSM-III-R Axis I and II psychiatric diagnoses in hospitalized adolescents with and without conduct disorder. The spectrum of psychopathology associated with conduct disorder, especially personality disorder symptoms and diagnoses, remains largely unexplored. METHOD: Twenty-five inpatients were evaluated using the Diagnostic Interview for Children and Adolescents, Adolescent Version (DICA-R-A); the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Epidemiologic Version (K-SADS-E) (panic disorder and agoraphobia only); and the Structured Interview for DSM-III-R Personality Disorders (SIDP-R). RESULTS: Fifty-two percent met criteria for conduct disorder, and the majority of these had comorbid substance abuse, attention-deficit hyperactivity disorder, and major depression. The diagnosis of conduct disorder was also associated with fulfilling criteria for multiple Axis II personality disorders, particularly passive aggressive and histrionic. Nearly three personality disorders per subject were found in those with conduct disorder, while those without conduct disorder averaged just over one personality disorder. There was a trend for female subjects with conduct disorders to have more frequent and varied personality disorder diagnoses. For the entire sample, males were significantly more likely to have conduct disorder, and females were significantly more likely to have borderline personality disorder. CONCLUSION: These findings support conduct disorder as a multifaceted illness composed of diverse Axis I and II characteristics. Long-term follow-up studies are needed to determine the outcome of personality disorder diagnoses made in adolescents with and without conduct disorder.

[Diagnosis and treatment of personality disorders].

Personality disorders are characterized by behaviour that is subjectively distressing or causes trouble in relation to other people. Severe personality disorders, formerly called psychopathy, are nowadays often called borderline disorders. Mild personality disorders, called character neuroses, are much more common. The article reviews these disorders within the perspective of general practice.

Adolescent psychopathy in relation to delinquent behaviors, conduct disorder, and personality disorders.

The purpose of this study was to explore the relationship between psychopathy as measured by The Revised Psychopathy Checklist (PCL-R) and delinquent behaviors, conduct disorder, and personality disorders in psychiatrically hospitalized adolescents. Thirty adolescent inpatients were assessed for psychopathy, delinquent behaviors, DSM-III-R Axis I disorders, and personality disorders using the Revised Psychopathy Checklist (PCL-R), the Diagnostic Interview for Children and Adolescents (DICA-R), and the Structured Interview for DSM-III-R Personality Disorders (SIDP-R). Significant relationships were noted between elevated PCL-R psychopathy scores and delinquent behaviors, conduct disorder, and narcissistic personality disorder. The validity of the PCL-R as a measure of psychopathy in adolescence was supported. Longitudinal studies are needed to clarify the clinical application of the PCL-R to adolescent populations.

The comorbidity of eating disorders and personality disorders: a meta-analytic review of studies published between 1983 and 1998.

Comorbid personality disorders in eating disordered patients may seriously affect the treatment and course of their illness. Several studies show such a comorbidity, though with inconsistent findings. Qualitative reviews attribute this to methodological shortcomings, but the qualitative method may itself create new shortcomings. To circumvent this, the present, more extensive review applies a meta-analytic approach. Using the databases MEDLINE and PSYCHLIT, the 28 articles published between 1983 and 1998 that presented empirical evidence for an eating disorder and personality disorder comorbidity suitable for meta-analysis were included. We found a higher proportion of eating disordered patients with any personality disorder (average proportion = 0.58) related to comparison groups (average proportion = 0.28). Compared with anorexia nervosa patients, a higher proportion of patients with bulimia nervosa had a concurrent cluster B personality (average proportion = 0.44) and a borderline personality disorder (average proportion = 0.31). However, no differences between anorexia nervosa and bulimia nervosa patients in proportions of cluster C were found (average proportion = 0.45 and 0.44 respectively). Patients with eating disorders and patients with bulimia nervosa in particular, should be routinely assessed for a concurrent personality disorder using structured clinical interviews. In future research, more stringent assessment procedures are highly recommended to address the question of causality between eating disorders and personality disorders, and how eating disorder symptoms and personality disorder symptoms are related to treatment effects.

Comorbidity of borderline personality disorder with other personality disorders in hospitalized adolescents and adults.

OBJECTIVE: The authors examined the comorbidity of borderline personality disorder with other personality disorders in a series of consecutively admitted adolescents. For comparison, the comorbidity of borderline personality disorder with other personality disorders was also examined in a series of adults consecutively admitted to the same hospital during the same period. METHOD: A total of 138 adolescents and 117 adults were reliably assessed with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. Sixty-eight adolescents and 50 adults met the diagnostic criteria for borderline personality disorder. The co-occurrence of other personality disorders in the group of subjects with borderline personality disorder was statistically compared to that in the group without borderline personality disorder, for adolescents and adults separately. RESULTS: For the adults, Bonferroni-corrected chi-square analysis revealed significant diagnostic co-occurrence with borderline personality disorder for antisocial personality disorder only. For the adolescents, borderline personality disorder showed significant co-occurrence with schizotypal and passive-aggressive personality disorders. CONCLUSIONS: In the adults, borderline personality disorder was significantly comorbid only with another cluster B disorder. The adolescents, by comparison, displayed a broader pattern of comorbidity of borderline personality disorder, encompassing aspects of clusters A and C. These results suggest that the borderline personality disorder diagnosis may represent a more diffuse range of psychopathology in adolescents than in adults.

Comorbidity of conduct disorder and personality disorders in an incarcerated juvenile population.

OBJECTIVE: Youths with conduct disorder extract an inordinate amount of time and money from the U.S. judicial system and taxpayers, yet studies pertaining to this population have been few. This study was undertaken to examine the co-occurrence of personality disorders and conduct disorder in a group of incarcerated children and adolescents and to raise the issue of the possibility of antisocial personality disorder in persons under the age of 18 years. METHOD: One hundred incarcerated juvenile offenders aged 11-17 years were randomly selected and then interviewed with the Diagnostic Interview for Children and Adolescents--Revised and the Structured Clinical Interview for DSM-III-R Personality Disorders to establish their psychiatric diagnoses. RESULTS: Eighty-seven percent of the group met the criteria for conduct disorder. Among those diagnosed as having conduct disorder, the only comorbid personality disorder that was present with significant frequency was antisocial personality disorder. The other comorbid personality disorder diagnoses that appeared most frequently were the borderline, narcissistic, paranoid, passive-aggressive, and dependent types. Borderline personality disorder was observed more frequently in the females than in the males with conduct disorder. CONCLUSIONS: The findings suggest that by using DSM-III-R criteria for adult personality disorders, one finds a considerable number of personality disorders in a young population with conduct disorder. The findings also show that youths manifest signs of antisocial personality disorder before they are 18 years of age, raising the question of how age should be incorporated into the diagnosis of personality disorder as DSM-IV is being prepared.

Special feature: family-genetic research strategies for personality disorders.

Personality disorders (PD) might be considered as extremes of personality dimensions varying in the general population or as attenuated variants of major psychiatric disorders. Both personality variation and major psychiatric disorders have been shown in twin and adoption studies, to be influenced by genes. Hence, it is likely that personality disorders are also under genetic control. However, direct evidence for influential familial and genetic factors is scarce. Various research strategies in this area are described and current evidence is reported. Gene-oriented approaches seem to be particularly promising. This strategy is illustrated for personality disorders in obligate carriers of mutations in the fragile-X gene.

Long-term outcome in personality disorders.

Personality disorders meeting DSM or ICD criteria represent the severe end of the broad spectrum of personality configurations involving maladaptive traits. The literature regarding long-term outcome of personality disorders is sparse. Most attention is devoted to formerly institutionalised patients with borderline, antisocial, or schizotypal disorders. Borderline patients at 10-25-year follow-up have a wide range of outcomes, from clinical recovery (50-60%) to suicide (3-9%). Certain factors (e.g. artistic talent) conduce to higher recovery rates, others (e.g. parental cruelty) to lower rates. Schizoid and schizotypal patients tend to remain isolated, and to lead marginal lives. The long-term outcome in antisocial persons is bleak if psychopathic traits are prominent. Personality traits and their corresponding disorders are egosyntonic, harden into habit, and are both slow to change and hard to modify. There is no one treatment of choice. Psychoanalysis and related methods work best within the anxious/inhibited group; cognitive/behavioural techniques are well suited to the disorders requiring limit setting and the amelioration of maladaptive habits.

Envy manifestations and personality disorders.

Personality disorders are frequently associated with socially unacceptable behaviours that might not be always considered deviant. On the other hand, envy has been linked with various forms of maladjustment such as interpersonal conflicts, low self-esteem, depression, anxiety, aggressiveness, and even criminal behaviour such as vandalism and even murder. According to the DSM-IV, none of the personality disorders, except the narcissistic personality, is formally associated with envy. Nevertheless, this "deadly sin" is so omnipresent in human relationships that it cannot be restricted only to the narcissistic personalities. Most scholars recognise that people would deny that they envy someone else since envy is socially considered as highly undesirable; verbal reports are expected to be biased. To circumvent this difficulty, a projective questionnaire is proposed. We constructed two questionnaires: a direct version (DV) and an indirect version (IV). The sample consisted of 786 students from high school and university. Results suggest that the indirect version provides a more accurate assessment of envy.

[Eating disorders and personality disorders--possible interactions and their therapeutic implications].

Personality disorders are defined by a characteristic and enduring pattern of behaviour and inner experience that deviates distinctly from culturally defined norms. Examples include social insecurity or even distrust leading to withdrawal, or patterns of impulsiveness, affective instability or, possibly, self-harm. Personality disorders are distinct from other psychiatric disorders primarily by their enduring character. The prevalence of personality disorders among patients with eating disorders depends on population characteristics. In a specialised outpatient clinic that serves a defined catchment area, nearly one third of patients will fulfill the diagnostic criteria for a personality disorder. Hospitalized patients or patients in more specialised units will surely show a considerably higher prevalence. Several modes of interaction between eating disorders and personality disorders could be hypothesized. The treatment of patients with eating disorder should take into account the subgroup with comorbid personality pathology and evaluation and treatment should be planned accordingly, though this requires time and expertise. The issue should also be acknowledged in primary health care and attention be paid to symptoms of eating disorder also in cases in which symptoms of a personality disorder are more pronounced.

Axis I disorders and personality disorders as risk factors for suicide.

There is a lack of psychological autopsy studies assessing the influence of axis I disorders on axis II disorders as risk factors for suicide. Therefore, we investigated the association between personality disorders, axis I disorders, and suicide. Psychiatric disorders were evaluated by a semi-structured interview including the Structured Clinical Interview for DSM-IV Axis I (SCID-I) and Personality Disorders (SCID-II) in 163 completed suicides (mean age 49.6 +/- 19.3 years; 64.4% men) and by personal interview in 396 population-based control persons (mean age 51.6 +/- 17.0 years; 55.8% men). In both genders, suicides significantly more often had personality disorders of all clusters than controls, also after adjustment for axis I disorders (p < 0.001, each). In addition, alcohol-related disorders, major depression, and co-occurrence of personality disorders of more than one cluster (men: OR = 16.13; women: OR = 20.43) remained independent predictors for suicide in both genders, "pure" cluster B personality disorders only in women and "pure" cluster C personality disorders only in men. In both genders, co-occurrence of personality disorders of more than one cluster contributed to risk of completed suicide after control for axis I psychiatric disorders and has to be considered as an independent risk factor for suicide.

Co-occurrence of personality disorders in persons with kleptomania: a preliminary investigation.

This study was conducted to examine the co-occurrence of personality disorders in a group of persons with kleptomania. Twenty-eight subjects with DSM-IV kleptomania were administered the Structured Clinical Interview for DSM-III-R Personality Disorders and a semistructured interview to assess demographics and clinical characteristics. Twelve subjects with kleptomania (42.9%) met criteria for at least one personality disorder. The most common were: paranoid (n = 5; 17.9%), schizoid (n = 3; 10.7%), and borderline (n = 3; 10.7%). Subjects with kleptomania combined with personality disorders had an earlier age of onset of stealing behavior (13.4 +/- 5.6 years compared with 27.4 +/- 14.2 years in those who had kleptomania only; t = 3.225; df = 26; p = .006). Severity of kleptomania symptoms did not differ among the Axis II comorbidities. Persons with kleptomania appear to have a high prevalence of personality disorders. Further studies are needed to understand the relationship of kleptomania to personality.

Differential diagnosis between borderline personality disorder and organic personality disorder following traumatic brain injury.

Organic personality disorder (OPD) is the traditional diagnostic category used to account for personality disturbances after traumatic brain injury (TBI). The recent use of Axis-II personality disorders, notably borderline personality disorder (BPD), has appeared in the TBI literature as an alternative to OPD. This would presumably offer a better description and understanding of the multiple clinical manifestations of these personality changes and disorders. This article offers a view that it is possible and fruitful to use both diagnoses in a complementary manner. An accurate recognition of the respective phenomenologies of both BPD and OPD is a key factor in achieving a differential diagnosis, including, if required, a dual diagnosis. The phenomenology of both conditions in reference to DSM-IV criteria is compared and illustrated through two clinical vignettes.
