Personality disorder diagnoses and age in inpatients with major depression

To ascertain the prevalence of personality disorder in elderly patients with major depression and to explore issues of diagnostic practice and bias, the authors reviewed triaxial diagnoses of 2322 psychiatric hospital inpatients with Axis I diagnoses of major depression. They found that Axis II diagnoses had been made in 367 cases (15.8%). Patients older than 65 years of age had a significantly lower rate of Axis II diagnoses. The age effect was greatest for women with comorbid physical illness. In contrast to the age-related decline in rate of Axis II diagnoses in general, the diagnosis of compulsive personality disorder increased with age and comprised 46% of all Axis II comorbidities in patients 65 years or older. Possible explanations and implications for future research are discussed.     

Comorbidity in an inpatient eating disordered population: clinical characteristics and treatment implications

Data are presented that describe the clinical characteristics of 96 patients treated at the C.F. Menninger Memorial Hospital, Topeka, Kansas, from November 1983 to June 1989. Their Axis I eating disorder diagnoses were as follows: 53 had diagnoses of bulimia; 21 had anorexia nervosa; 2 had both diagnoses; 17 had atypical disorders or eating disorders not otherwise specified; and 2 had a diagnosis of psychological factors affecting physical conditions. Seventy-three percent of the cohort were found to have either Axis I or Axis II disorders or both, comorbidity. Borderline personality disorder was found in 46% of the sample, although 20% of the patients with borderline disorders were diagnosed retrospectively. Depression was the largest comorbid Axis I diagnosis. Patient variables for sexual abuse, drug and alcohol addiction, purgative behaviors, and interpersonal relationships are also described. The authors conclude that a substantial subpopulation of eating disordered patients are significantly comorbid for other psychiatric illnesses. This high incidence of comorbidity may help explain the frequency of refractoriness of many eating disordered patients who do not respond to outpatient or short-term inpatient hospitalization. The authors recommend that additional research studies address the problems of the comorbid eating disordered patient and suggest that the findings be taken into account by clinicians and payers.     

Personality disorder assessments in acute depressive episodes: stability at follow-up

Assessment of personality disorders during the acute phase of major depression may be invalidated by the potential distortion of personality traits in depressed mood states. However, few studies have tested this assumption. We examined the stability of personality disorder diagnoses during and then after a major depressive episode (MDE). Subjects with major depression (N = 82) completed the 17-item Hamilton Depression Scale (HAM-17) and the Structured Clinical Interview for Axis II both at baseline during an MDE and at 3-month follow-up. We compared subjects who continued to meet DSM-IV criteria for the same Axis II diagnoses with patients whose diagnosis changed and patients with no DSM-IV personality disorder to determine the relationship to major depression and its severity. Sixty-six percent of subjects met DSM-IV criteria for at least one Axis II diagnosis at baseline and 80% had the same personality disorder diagnoses at follow-up. Thirty-four percent had a full remission of MDE at 3-month follow-up. Instability of Axis II diagnosis was associated with number of Axis II diagnoses at baseline (p = .036) and Hispanic ethnicity (p = .013). HAM-17 score change was unrelated to differences in the number of symptoms of personality disorders from baseline to follow-up, nor was remission from MDE on follow-up. Axis II diagnoses in acutely depressed patients reassessed after 3 months are often stable and not associated with remission of or improvement in major depression.     

Relationship between borderline personality disorder and Axis I diagnosis in severity of depression and anxiety

BACKGROUND: This study tested the hypothesis that subjects with borderline personality disorder irrespective of the presence or absence of an Axis I mood or anxiety disorder would exhibit greater severity of depression and anxiety than subjects with either a personality disorder other than borderline personality disorder or no personality disorder. METHOD: Two hundred eighty-three subjects from an outpatient psychiatry clinic were administered the following assessments: the Structured Clinical Interview for DSM-III-R (SCID) for Axes I and II, the Hamilton Rating Scales for Depression and Anxiety, the Beck Depression Inventory, and the Spielberger State-Trait Anxiety Inventory. Subjects were categorized into borderline personality disorder, other personality disorder, and no personality disorder categories and into present versus absent categories on Axis I diagnosis of depression and of anxiety. A 2-factor multiple analysis of variance compared personality disorder status and Axis I diagnosis on severity of depression by observer rating and self-report. The analysis was repeated for anxiety. RESULTS: As hypothesized, significant main effects were found for borderline personality disorder and for both depression and anxiety. Subjects with borderline personality disorder showed greater severity on both depression and anxiety rating scales than did patients with another personality disorder, who showed greater severity than did patients with no personality disorder. Axis I diagnosis was also associated with greater severity on depression or anxiety rating scales. These differences were found for both observer ratings and self-report. An interaction was also found for depression: Subjects with borderline personality disorder but without an Axis I diagnosis of depression rated themselves as more severely depressed on the Beck Depression Inventory than did subjects with another or no personality disorder who also had an Axis I diagnosis of depression. CONCLUSION: Implications from the study are discussed including the need to assess for borderline personality disorder in research studies of depression and anxiety and to integrate treatments for borderline personality disorder into depression and anxiety treatment to maximize clinical outcomes.     

Chronic depression and comorbid personality disorders: response to sertraline versus imipramine

BACKGROUND: Chronic subtypes of depression appear to be associated with high rates of Axis II personality disorder comorbidity. Few studies, though, have systematically examined the clinical correlates of Axis II personality disorder comorbidity or its effect on treatment response or time to response. METHOD: 635 patients diagnosed with DSM-III-R chronic major depression or "double depression" (dysthymia with concurrent major depression) were randomized to 12 weeks of double-blind treatment with either sertraline or imipramine between February 1993 and December 1994. Axis II diagnoses were made using the personality disorders version of the DSM-III-R Structured Clinical Interview. The effect of study treatment was measured utilizing the Hamilton Rating Scale for Depression and the Clinical Global Impressions scale. RESULTS: Forty-six percent of patients met criteria for at least 1 comorbid Axis II personality disorder, with cluster C diagnoses being the most frequent at 39%; 21% met criteria for at least 2 Axis II personality disorders. A cluster C diagnosis was associated with significantly higher rates of early-onset depression (before age 21; 47% vs. 32% for no cluster C; p =.005) and comorbid anxiety disorder (34% vs. 18% for no cluster C; p <.001). Overall, the presence of Axis II personality disorder comorbidity had minimal-to-no effect on the ability to achieve either an antidepressant response or remission and had inconsistent effects on time to response. The presence of Axis II personality disorder comorbidity did not appear to reduce functional and quality-of-life improvements among patients responding to acute treatment with sertraline or imipramine. CONCLUSION: In this treatment sample, rates of Axis II personality disorder comorbidity were substantial in patients suffering from chronic forms of depression. Axis II personality disorder comorbidity did not appear to diminish symptomatic response to acute treatment or associated improvement in functioning and quality of life.     

DSM-III symptom disorders (Axis I) and personality disorders (Axis II) in an outpatient population

Type and prevalence of Axis I and Axis II disorders (DSM-III) were assessed in a sample of 298 consecutive psychiatric outpatients. The instruments used were SCID and SIDP. About half of the Axis I diagnoses consisted of different subgroups of depression. Most patients had more than one diagnosis, anxiety being the second most common disorder. Eighty one percent of the subjects met the criteria for a personality disorder diagnosis; half of them obtained more than one Axis II diagnosis. Personality disorder was more common among men than among women. Avoidant and dependent personality disorders constituted the most frequent diagnoses.     

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.     

Interactions between depression and borderline personality disorder. A pilot study

Although many nosologists advocate the autonomy of borderline personality disorder (BPD), its heterogeneity led to demands that it be absorbed into the affective disorder spectrum. This study attempted to determine if (a) BPD and affective disorders overlapped and (b) if BPD characteristics were differentially associated with specific Axis I, DSM-III diagnoses. Forty-three BPD inpatients were rated retrospectively on 29 variables, including BPD characteristics from Gunderson's diagnostic interview for borderlines (DIB). chi 2 analyses were performed for each of 28 variables in 56 contingency tables whose independent variables were dysthymia/other Axis I diagnoses or depression/no depression. BPD inpatients with dysthymia had more impaired occupational functioning and greater use of splitting. Also, depressed BPDs were in general more dependent, empty and bored, and suicidal.     

Gender-related distribution of personality disorders in a sample of patients with panic disorder.

OBJECTIVE: We examined gender differences in the frequency of DSM-IV personality disorder diagnoses in a sample of patients with a diagnosis of panic disorder (PD). METHOD: One hundred and eighty-four outpatients with a principal diagnosis of PD (DSM-IV) were enrolled. All patients were evaluated with a semi-structured interview to collect demographic and clinical data and to generate Axis I and Axis II diagnoses in accordance with DSM-IV criteria. RESULTS: Males were significantly more likely than females to meet diagnoses for schizoid and borderline personality disorder. Compared to males, females predominated in histrionic and cluster C diagnoses, particularly dependent personality disorder diagnoses. A significant interaction was found between female sex and agoraphobia on personality disorder (PD) distribution. CONCLUSIONS: Male PD patients seem to be characterized by more severe personality disorders, while female PD patients, particularly with co-morbid agoraphobia, have higher co-morbidity rates with personality disorders belonging to the 'anxious-fearful cluster'.     

Biologic markers in borderline personality disorder: a review

The use of biologic markers in the evaluation of borderline personality disorder (BPD) patients is reviewed. Many patients with Axis II BPD have coexisting Axis I diagnoses of which depression is the most commonly reported. Biologic markers have not aided in the diagnosis of BPD, but some markers, particularly EEG sleep, are not only abnormal in BPD, but also appear to discriminate Axis I depression from other Axis I codiagnoses. Monoamine oxidase, in vitro red blood cell lithium ratio, and P300 auditory evoked potential when used alone or in a combined diagnostic approach, show promise in identifying these codiagnoses as well. Dexamethasone suppression and thyrotropin-releasing hormone tests appear nonspecific in this population. Pharmacologic trials have demonstrated that some BPD patients have good therapeutic response to antipsychotics and tranylcypromine and poor response to alprazolam.     

Treatment resistant depression: a clinical perspective

One hundred and fourteen patients with a diagnosis of "treatment resistant depression" (TRD) were assessed and treated at a Mood Disorders Clinic. Diagnostically, 52 (45.6%) subjects met criteria for bipolar disorder, 49 (42.9%) for recurrent depression, and 13 (11.4%) patients did not fulfill diagnostic criteria for affective disorder which explained their treatment resistance. With appropriate, individualized treatment, 59 of 98 (60.2%) patients had complete symptom remission based on clinical and psychometric ratings (initial Ham-D 26.7, final Ham-D 5.9). Eighteen of 98 patients had partial remission (final Ham-D 15.9) with vigorous pharmacological interventions, and 8 subjects exhibited "absolute" TRD (final Ham-D 23.4). The results suggest the value of specialized mood disorder services. The partial and absolute TRD's were more likely to be older, received more Axis II diagnoses, and had previous histories of drug or alcohol abuse.     

Personality disorders in parasuicide

To examine the prevalence of personality disorders in a representative sample of patients admitted to inpatient care after a parasuicide, 64 consecutive patients were investigated with structured interviews for DSM-IV personality disorders and clinical interviews for Axis I disorders and suicidal behaviour. We found a borderline personality disorder (BPD) as principal diagnosis in 55% of the subjects and some other personality disorder (OPD) in an additional 23%. Multiple Axis II disorders were significantly more common in the BPD group, in which 71% met criteria for three or more personality disorders, compared with 7% in the OPD group. In the BPD group 20% did not have a concomitant Axis I disorder, whereas this was very uncommon in the other groups. A relatively large proportion (34%) in the BPD group used other parasuicide methods than drug intoxication, whereas in the other groups this was rare. The mean number of previous parasuicidal acts was significantly higher in the BPD group, in which 57% had three or more previous parasuicides, and a high proportion (60%) also had repeated a parasuicidal act within the last year. In the BPD group 69% had ongoing outpatient treatment. Only 25% of these outpatients had a borderline personality disorder reported in the hospital records, suggesting that the personality disorder might go undiagnosed. The study gives support to the importance of a focused and structured personality disorder diagnosis in customizing treatment for the person with a recent parasuicide.

Is comorbidity of posttraumatic stress disorder and borderline personality disorder related to greater pathology and impairment?

OBJECTIVE: The authors examined whether patients with comorbid borderline personality disorder and posttraumatic stress disorder (PTSD) have a more severe clinical profile than patients with either disorder without the other. METHOD: Outpatients with borderline personality disorder without PTSD (N=101), PTSD without borderline personality disorder (N=121), comorbid borderline personality disorder and PTSD (N=48), and major depression without PTSD or borderline personality disorder (N=469) were assessed with structured interviews for psychiatric disorders and for degree of impairment. RESULTS: Outpatients with diagnoses of comorbid borderline personality disorder and PTSD were not significantly different from outpatients with borderline personality disorder without PTSD, PTSD without borderline personality disorder, or major depression without PTSD or borderline personality disorder in severity of PTSD-related symptoms, borderline-related traits, or impairment. CONCLUSIONS: The additional diagnosis of PTSD or borderline personality disorder does little to augment the pathology or dysfunction of patients who have either disorder without the other.     

Symptoms of depression and anxiety (MHI) following acute medical/surgical hospitalization and post-discharge psychiatric diagnoses (DSM) in 839 geriatric US veterans

OBJECTIVE: We addressed the relatively unexplored use of screening scores measuring symptoms of depression and/or anxiety to aid in identifying patients at increased risk for post-discharge DSM-IV Axis I diagnoses. We were unable to find such studies in the literature. METHOD: Elderly veterans without recent psychiatric diagnoses were screened for depression and anxiety symptoms upon admission to acute medical/surgical units using the Mental Health Inventory (MHI). Following discharge, those who had exceeded cut-off scores and had been randomized to UPBEAT Care (Unified Psychogeriatric Biopsychosocial Evaluation and Treatment, a clinical demonstration project) were evaluated for DSM diagnoses. We report on 839 patients, mostly male (96.3%; mean age 69.6 +/- 6.7 years), comparing three groups, i.e. those meeting screening criteria for symptoms of (i) depression only; (ii) anxiety only; and (iii) both depression and anxiety. RESULTS: Despite absence of recent psychiatric history, 58.6% of the 839 patients received a DSM diagnosis post-discharge (21.8% adjustment; 15.4% anxiety; 7.5% mood; and 14.0% other disorders). Patients meeting screening criteria for both depression and anxiety symptoms received a DSM diagnosis more frequently than those meeting criteria for anxiety symptoms only (61.9% vs 49.0%, p = 0.017), but did not differ significantly from those meeting criteria for depressive symptoms only (61.9% vs 56.8%, p = 0.174). Although exceeding the MHI screening cut-off scores for depression, anxiety, or both helped to identify patients with a post-discharge DSM diagnosis, the actual MHI screening scores failed to do so. CONCLUSION: Screening hospitalized medical/surgical patients for symptoms of depression, anxiety, and particularly for the combination thereof, may help identify those with increased risk of subsequent DSM diagnoses, including adjustment disorder.     

Trait-state artifacts and the diagnosis of personality disorders

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.     

The nosologic status of borderline personality: clinical and polysomnographic study

The REM latencies of 24 nonschizotypal borderline outpatients--who were not in the midst of a major depressive episode--were in the range of those of 30 patients with primary major depression but were significantly shorter than those of 16 patients with nonborderline personality disorders and 14 nonpsychiatric controls. Also, more of the borderline subjects had lifetime diagnoses of affective disorder, such as dysthymic, cyclothymic, and bipolar II disorder, and of a spectrum of anxiety and somatization disorders. The authors conclude that contemporary operational criteria for borderline disorder identify a wide net of temperamental disorders with strong affective coloring rather than a unitary nosologic entity.     

Axis I disorders in ER patients with atypical chest pain

To examine the contribution of psychopathology to emergency room (ER) visits for atypical chest pain, we administered two screening measures and the Structured Clinical Interview for DSM III-R (SCID) to thirty-five subjects within seventy-two hours of their ER visit. Follow-up SCID interviews were completed in thirty subjects at five to twelve months. Sixty percent of the sample had an initial Axis I diagnosis, predominately affective (34%) and anxiety (46%) disorders. Forty percent had multiple diagnoses initially. The most common diagnoses were panic disorder (31%) and major depression (23%). At follow-up 47 percent had Axis I diagnoses, 30 percent had multiple diagnoses, with only slightly decreases rates for panic disorder (27%) and major depression (17%). Many subjects had lost, gained, or switched diagnoses by follow-up, in spite of one consistent rater and a few subjects seeking treatment. ER physicians often do not recognize these psychiatric disorders in chest pain patients. The high risk of suicide in panic disorder and depression, and the high cost of disability in recurrent chest pain make it essential that ER physicians include these disorders in the differential of atypical chest pain.     

Axis I and Axis II diagnoses in patients with chronic idiopathic urticaria

OBJECTIVE: This study presents the current prevalence of Axis I and Axis II psychiatric diagnoses and factors associated with the existence of Axis I psychiatric disorders in patients with chronic idiopathic urticaria (CIU). METHOD: The study sample was composed of 89 patients with CIU and 64 control subjects. Axis I and Axis II psychiatric disorders were ascertained by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition and the Structured Clinical Interview for DSM, Revised Third Edition Personality Disorders, respectively. RESULTS: Of patients with CIU, 44 (49.4%) had at least one Axis I diagnosis, and 40 (44.9%) had at least one personality disorder. The most common Axis I disorder was obsessive-compulsive disorder (25.8%), and the most common Axis II disorder was obsessive-compulsive (30.3%) personality disorder in patients with CIU. Obsessive-compulsive disorder, major depression, obsessive-compulsive and avoidant personality disorders were more prevalent in patient group compared to control group. Obsessive-compulsive and avoidant personality disorders were related to the existence of Axis I disorders in patients with CIU. CONCLUSION: Psychiatric morbidity seems to be a frequent healthy problem in patients with CIU.
