Comorbid personality disorders in subjects with panic disorder: do personality disorders increase clinical severity?

Personality disorders are common in subjects with panic disorder. Personality disorders have been shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders affect clinical severity in subjects with panic disorder. This study included 122 adults (71 women, 41 men) who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ( DSM-IV ) criteria for panic disorder (with or without agoraphobia). Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders, and the Panic and Agoraphobia Scale, Global Assessment Functioning Scale, Beck Depression Inventory, and State-Trait Anxiety Inventory. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, sexual abuse, and early onset of disorder. The rates of comorbid Axes I and II psychiatric disorders were 80.3% and 33.9%, respectively, in patients with panic disorder. Patients with panic disorder with comorbid personality disorders had more severe anxiety, depression, and agoraphobia symptoms, had earlier ages at onset, and had lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, respectively, in subjects with panic disorder. The rate of patients with panic disorder and a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was borderline personality disorder. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictors of suicidal ideation were comorbid major depression and avoidant personality disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Borderline personality disorder may be the predictor of a history of sexual abuse and early onset in patients with panic disorder. Paranoid and borderline personality disorders may be associated with a high frequency of suicide attempts in patients with panic disorder.     

Self-report measures of anxiety: Are they suitable for older adults?

OBJECTIVES: To assess the performance of four self-report measures of anxiety in an older adult population. METHOD: Forty older adults with current or previous anxiety symptoms completed four self-report measures of anxiety (Beck Anxiety Inventory, State Trait Anxiety Inventory, Hospital Anxiety and Depression Scale and Visual Analogue Scale) and received an independent diagnostic assessment and rating of anxiety severity. After a minimum of four months, participants were re-assessed on all measures. RESULTS: The self-report measures most suited for anxiety screening and assessing severity when compared to the independent assessment were the Beck Anxiety Inventory (BAI), the anxiety scale from the Hospital Anxiety and Depression Scale (HADS-A) and State Trait Anxiety Inventory-Trait form (STAI-T). However, participants made an unacceptably high number of errors using the STAI-T, making the BAI and HADS-A the most suitable measures for older adults. The Visual Analogue Scale (VAS) performed poorly in both screening and measuring severity. All self-report measures were poor at detecting change as evaluated by the independent assessment. CONCLUSION: There was no single measure that performed adequately in screening, measuring severity and monitoring changes, suggesting that measures may need to be adapted if they are to be used in an older adult population. The lack of appropriately designed self-report measures with adequate normative data for older people presents a barrier to future research.     

The characteristics of the comorbidity between social anxiety and separation anxiety disorders in adult patients

Abstract

Objective: In the present study, we compared social anxiety disorder (SAD) patients with (n?=?31) and without childhood and adulthood separation anxiety disorder (SeAD) (n?=?50) with respect to suicidal behavior, avoidant personality disorder (AvPD), other anxiety disorders (ADs), and major depression as well as some sociodemographic variables.

Methods: In assessment of patients, we used Structured Clinical Interview for Separation Anxiety Symptoms, childhood and adulthood Separation Anxiety Symptom Inventories, Liebowitz Social Anxiety Scale, The SCID-II Avoidant Personality Disorder Module, Beck Depression Inventory, and Beck Scale for Suicidal Ideation.

Results: SAD patients with SeAD had higher comorbidity rates of AvPD, other lifetime ADs and panic disorder, and current major depression than those without SeAD. The current scores of SAD, depression, and suicide ideation and the mean number of AvPD symptoms were significantly higher in comorbid group compared to pure SAD subjects. The SAD and SeAD scores had significant associations with current depression, suicide ideations, and AvPD. The mean number of AvPD criteria and the current severity of depression were significantly associated with the comorbidity between SAD and SeAD.

Conclusion: Our findings might indicate that the comorbidity of SeAD with SAD may increase the risk of the severity of AvPD and current depression.     

The severity of Internet addiction risk and its relationship with the severity of borderline personality features,childhood traumas,dissociative experiences,depression and anxiety symptoms among Turkish University Students

The aim of this study was to investigate the relationship of Internet addiction (IA) risk with the severity of borderline personality features, childhood traumas, dissociative experiences, depression and anxiety symptoms among Turkish university students. A total of 271 Turkish university students participated in this study. The students were assessed through the Internet Addiction Scale (IAS), the Borderline Personality Inventory (BPI), the Dissociative Experiences Scale (DES), the Childhood Trauma Questionnaire (CTQ-28), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The rates of students were 19.9% (n=54) in the high IA risk group, 38.7% (n=105) in the mild IA risk group and 41.3% (n=112) in the group without IA risk. Correlation analyses revealed that the severity of IA risk was related with BPI, DES, emotional abuse, CTQ-28, depression and anxiety scores. Univariate covariance analysis (ANCOVA) indicated that the severity of borderline personality features, emotional abuse, depression and anxiety symptoms were the predictors of IAS score, while gender had no effect on IAS score. Among childhood trauma types, emotional abuse seems to be the main predictor of IA risk severity. Borderline personality features predicted the severity of IA risk together with emotional abuse, depression and anxiety symptoms among Turkish university students.     

Relationship of alexithymia and dissociation with severity of borderline personality features in male substance-dependent inpatients

The aim of this study was to evaluate possible interactions between severity of borderline personality features (BPFs), dissociative experiences, and alexithymia among substance-dependent men while controlling for their current age, depression, and anxiety. Participants were 200 substance-dependent men consecutively admitted to a dependency treatment unit. The Borderline Personality Inventory, the Toronto Alexithymia Scale, the Dissociative Experiences Scale, the Beck Depression Inventory, and the Spielberger State-Trait Anxiety Inventory were administered to all participants. Severity of negative affect, alexithymia, dissociative experiences, and BPF were correlated with each other. Being younger, severity of dissociative experiences, difficulty in identifying feelings, depression, and trait anxiety predicted the severity of BPF in linear regression analysis. These findings suggest that alexithymia and dissociative experiences may be a way of coping with depression and chronic anxiety, but they also seem to be related to the severity of BPF independent of the negative affect and from each other.     

Poststroke depression and anxiety: different assessment methods result in variations in incidence and severity estimates

Patients with right and left hemisphere stroke (RH, LH) and a control group (CG) were administered a structured clinical interview (SCID-R) and rating scales for anxiety and depression (Center for Epidemiologic Studies Depression Scale, Beck Anxiety Inventory, and Hamilton Depression Rating Scale). The three groups did not differ when compared for the mean level of distress on the rating scales or frequency of mood or anxiety disorder diagnosis using the SCID-R. By contrast, participants in the LH group were more likely to be classified as distressed using rating scales cutoff scores and on measures of severity when compared only to the RH group. The rating scales were sensitive to psychiatric disorders, but lacked specificity in all groups. There were significant correlations between scales suggesting the rating scales measure a common factor in the controls, while in the stroke groups associations were weaker and less likely to be significant. Together, these results suggest the need for caution in using rating scales of depression and anxiety in neurologic patients and support the notion that these scales are sensitive to distress rather than specific for identifying depressive and anxiety disorders.     

History of suicide attempt in male substance-dependent inpatients and relationship to borderline personality features, anger, hostility and aggression

The aim of this study was to investigate the relationship between severity of borderline personality features and history of suicide attempt (HSA) in male substance-dependent inpatients and the effect of anger, hostility and aggression on this relationship. Further, the effect of some variables that may be related to suicide and/or borderline personality, such as age at inception of regular substance use, substance of dependence (alcohol/drug), depression, and both state and trait anxiety, were controlled. Participants were 200 consecutively admitted male substance-dependent inpatients. Patients were investigated with the Borderline Personality Inventory (BPI), the Buss-Perry Aggression Questionnaire (AQ), the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). Among substance-dependent inpatients, 33.0% (n = 66) were identified as the group with HSA. Mean scores employment status, marital status and duration of education did not differ between groups, whereas current age and age at onset of regular substance use were lower in group with HSA. Mean scores of BPI, AQ and its subscales (anger, hostility and physical/verbal aggression), BDI and STAI were higher in the HSA group. In addition, the rates of drug dependency and borderline personality disorder were higher in this group. The severity of borderline personality symptoms was highly correlated with subscales of the AQ, depression and anxiety, whereas it was negatively correlated with age at onset of regular substance use. The severity of anger and borderline personality features predicted HSA in the logistic regression model. Results suggest that, to reduce the risk of suicide attempt among substance-dependent patients, the feeling of anger must be the target of evaluation and treatment among those with borderline personality features.     

Poststroke Depression and Anxiety: Different Assessment Methods Result in Variations in Incidence and Severity Estimates

Patients with right and left hemisphere stroke (RH, LH) and a control group (CG) were administered a structured clinical interview (SCID-R) and rating scales for anxiety and depression (Center for Epidemiologic Studies Depression Scale, Beck Anxiety Inventory, and Hamiliton Dpression Rating Scale). The three groups did not differ when compared for the mean level of distress on the rating scales or frequency of mood or anxiety disorder diagnosis using the SCID-R. By contrast, participants in the LH group were more likely to be classified as distressed using rating scales cutoff scores and on measures of severity when compared only to the RH group. The rating scales were sensitive to psychiatric disorders, but lacked specificity in all groups. There were significant correlations between scales suggesting the rating scales measure a common factor in the controls, while in the stroke groups associations were weaker and less likely to be significant. Together, these results suggest the need for caution in using rating scales of depression and anxiety in neurologic patients and support the notion that these scales are sensitive to distress rather than specific for identifying depressive and anxiety disorders.     

Anxiety disorders and their clinical correlates in multiple sclerosis patients

OBJECTIVE: To assess prevalence rates and clinical correlates of anxiety disorders in patients with multiple sclerosis (MS). METHODS: Demographic and neurological data were collected on 140 consecutive clinic attendees, and their lifetime and point prevalences of anxiety disorders were determined with the Structured Clinical Interview for DSM-IV disorders (SCID-IV). All subjects completed the self-report Hospital Anxiety and Depression Scale (HADS). Suicidal intent was rated with the Beck Suicide Scale (BSS), psychosocial stressors and supports were quantified with Social Stress and Support Interview (SSSI), and cognition assessed with Neuropsychological Screening Battery for MS. RESULTS: The lifetime prevalence of any anxiety disorder was 35.7%, with panic disorder (10%), obsessive compulsive disorder (8.6%), and generalized anxiety disorder (18.6%), the most common diagnoses obtained. Subjects with an anxiety disorder were more likely to be female, have a history of depression, drink to excess, report higher social stress and have contemplated suicide. The diagnosis of an anxiety disorder had been missed in the majority of subjects, therefore, they had not received treatment. A discriminant function analysis identified a series of variables that correctly classified 75% of patients with an anxiety disorder. CONCLUSION: Anxiety disorders are common in patients with MS, but are frequently overlooked and under-treated. Risk factors include being female, a co-morbid diagnosis of depression, and limited social support. Clinicians should evaluate all MS subjects for anxiety disorders, as they represent a treatable cause of disability in MS.     

Psychiatric disorders in idiopathic-isolated focal dystonia

Idiopathic-isolated focal dystonia (IIFD) is a movement disorder characterised by involuntary, sustained muscle contractions, leading to abnormal postures. Psychopathology is frequent in patients with IIFD, and while traditionally this was thought to be a secondary phenomenon, there is emerging evidence for shared neurobiological mechanisms. We conducted a single-centre cross-sectional study of 103 consecutive patients with IIFD and two comparison groups: 78 consecutive patients with hemifacial spasm (HFS) and 93 healthy control subjects. Assessments with regard to psychiatric disturbances were performed using self-report questionnaires, including the self-report version of the Yale–Brown Obsessive Compulsive Scale (Y-BOCS-SR), the Beck Anxiety Inventory (BAI), and the Beck Depression Inventory (BDI). Compared to healthy control subjects and patients with HFS, the IIFD group had higher OCS, anxiety, and depression scores as measured by the Y-BOCS-SR, BAI, and BDI, respectively. The Y-BOCS-SR, BAI, and BDI were highly correlated across all the subjects. Logistic regression analysis showed that the main driver of high obsessive–compulsive symptom scores, irrespective of neurological diagnosis, was the BDI, whereas it was BAI (and not BDI), that drives the association between the psychiatric rating scale scores and the neurological diagnosis. Our findings suggest that while clinically significant obsessive–compulsive symptoms are over-represented in IIFD patients relative to controls, the BAI may have better discriminatory power to distinguish between the psychiatric symptoms in IIFD patients.     

Conversion disorder in children and adolescents: a 4-year follow-up study

OBJECTIVE: To assess the outcome of conversion disorder in children and adolescents and to identify factors affecting the prognosis. METHOD: Forty adolescents with conversion disorder were reevaluated 4 years after their initial interview. Changes in demographic and clinical data and the presence of any mood and anxiety disorders were recorded using the Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I). In addition, Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) were applied. RESULTS: Thirty-four patients (85%) had completely recovered from their conversion symptoms and two patients had improved (5%), whereas only four (10%) were unchanged. Fourteen (35%) patients received the diagnosis of mood and/or anxiety disorder. Favourable outcome was associated with early diagnosis (P=.04) and good premorbid adjustment (P=.01). CONCLUSION: Conversion disorder has a favourable outcome in children and adolescents. However, mood and/or anxiety disorders are encountered at a considerable rate in these patients even after recovery from conversion symptoms. Long clinical follow-up seems appropriate in children and adolescents with conversion disorder.     

Anxiety and depression in bronchial asthma

The aim of the study was to establish the frequency and follow the clinical course of depression and anxiety in patients with bronchial asthma. 57 patients (37 atopic and 20 nonatopic) with mild and moderate bronchial asthma and 53 subjects matched for age and sex as control groups were included in the study. The following questionnaires: Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Scale (HADS) were used to evaluate anxiety and mood state. The level and prevalence of anxiety and depression were significantly higher in both groups of asthmatics in comparison to healthy subjects. Symptoms were mild and moderate. Nonatopic patients were more depressed and anxious than atopics.     

Anxiety and depressive symptoms in clinically isolated syndrome and multiple sclerosis

Depression and anxiety have been reported in patients with multiple sclerosis (MS) and in patients with clinically isolated syndrome (CIS). However, the precise mechanisms that lead to depressive and anxiety symptoms in these patients are still unclear. In this study we evaluated with the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) patients with MS and CIS and compared them to controls. We also correlated BDI and BAI scores with clinical parameters. Kruskall-Wallis followed by Dunn's Multiple Comparison Test, Chi-square and Spearman test were used. Patients with MS had higher depressive and anxiety scores than controls. The BDI and BAI scores of patients with CIS were not significantly different from controls. There was a positive correlation between BDI, BAI and EDSS. Our results corroborate the view that MS patients have higher depression and anxiety levels than control subjects. Anxiety and depressive symptoms also seem to progress according to the severity of the disease.     

The relationship of personality disorders to treatment outcome in depressed outpatients

BACKGROUND: Many clinicians believe that depressed patients with comorbid personality disorder(s) may respond differently to standard treatments than patients with depression alone. Personality disorders appear to be common among patients with depression, suggesting potentially significant treatment implications for a large group of patients. METHOD: Subjects with DSM-III-R major depression were recruited for a study looking at prediction of antidepressant response. All patients were assessed using the Structured Clinical Interviews for DSM-III-R Axis I and Axis II, as well as rated on the Hamilton Rating Scale for Depression and the Montgomery-Asberg Depression Rating Scale (MADRS). Patients were then randomly assigned to treatment with fluoxetine or nortriptyline and reassessed at 6 weeks. The major outcome measure was percentage reduction in MADRS scores. RESULTS: Of the 183 patients who completed the personality disorder assessment, 45% had at least 1 comorbid personality disorder. Subjects with comorbid personality disorders were slightly younger, more depressed at baseline, had poorer social adjustment, more general psychopathology, and more chronic depression. Despite these differences, the presence of a comorbid personality disorder did not adversely affect overall outcome at 6 weeks, but there was an interaction between having a comorbid personality disorder and drug type. The major effect was that patients with a cluster B personality disorder did relatively poorly on nortriptyline compared with fluoxetine treatment. CONCLUSION: The finding that the presence of a comorbid personality disorder does not affect overall treatment response is similar to that reported by some recent studies. The finding that patients with cluster B personality disorders respond poorly to nortriptyline is also consistent with a small literature on borderline personality disorder.     

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.     

Self-injurious skin picking: clinical characteristics and comorbidity.

BACKGROUND: Repetitive skin picking, a self-injurious behavior that may cause severe tissue damage, has received scant empirical attention. The authors examined the demographics, phenomenology, and associated psychopathology in a series of 31 subjects with this problem. METHOD: Subjects were administered the Structured Clinical Interview for DSM-IV for Axis I and Axis II disorders. They also completed several mood questionnaires and a new self-report inventory designed to assess phenomenology, triggers, cognitions, emotions, and consequences associated with skin picking. RESULTS: The mean age at onset on self-injurious skin picking was 15 years, and the mean duration of illness was 21 years. All subjects picked at more than one body area, and the most frequent sites of skin picking were pimples and scabs (87%). The most common comorbid Axis I diagnoses were obsessive-compulsive disorder (OCD; 52%), alcohol abuse/dependence (39%), and body dysmorphic disorder (32%). Forty-eight percent (N = 15) of the subjects met criteria for at least one mood disorder, and 65% (N = 20) for at least one anxiety disorder. The most common Axis II disorders were obsessive-compulsive personality disorder (48%) and borderline personality disorder (26%). CONCLUSION: Self-injurious skin picking is a severe and chronic psychiatric and dermatologic problem associated with high rates of psychiatric comorbidity. It may be conceptualized as a variant of OCD or impulse-control disorder with self-injurious features and may, in some cases, represent an attempt to regulate intense emotions.     

Personality disorders, history of trauma, and posttraumatic stress disorder in subjects with anxiety disorders

The purpose of the study was to examine the association of personality disorders, history of trauma, and posttraumatic stress disorder (PTSD) in a large sample of subjects with anxiety disorders. Categorical and continuous indices of personality disorders were compared in three groups from the Harvard/Brown Anxiety Disorders Research Project (HARP): subjects with no history of trauma (n = 403), subjects with a history of trauma but no history of PTSD (n = 151), and subjects with a current or past diagnosis of PTSD (n = 68). Subjects with PTSD were more likely to meet criteria for borderline or self-defeating personality disorder than subjects in the other two groups. PTSD subjects also had higher scores on the continuous measures (total number of criteria met) for borderline and self-defeating personality disorder than the other two groups. The findings suggest that a diagnosis of PTSD rather than a history of trauma is associated with borderline and self-defeating personality disorder features. Alternative conceptualizations of axis II features in individuals with PTSD are discussed.     

Clinical correlates of self-mutilation in Turkish male substance-dependent inpatients

OBJECTIVE: The aim of this study was to evaluate the prevalence of self-mutilation (SM) in male substance-dependent inpatients, and to investigate the relationship of SM with childhood abuse and neglect, axis I disorders and personality disorders. METHODS: Participants were 112 consecutively admitted male substance dependents (56 alcohol and 56 drug). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV (SCID-I, Turkish version). Patients were evaluated by the Childhood Abuse and Neglect Questionnaire, SCID-I, SCID-II, Beck Depression Inventory and Beck Anxiety Inventory. RESULTS: Among substance-dependent patients, SM was found to be present in 33% (SM group). Mean age and educational status were lower in the SM group. Moreover rates of being single, history of childhood physical and emotional abuse and neglect, suicide attempt history and personality disorder were higher. Mean depression and anxiety scores were also higher in the SM group. Personality disorder, physical abuse, suicide attempt history and drug dependency were predictors for SM. CONCLUSIONS: SM is more common in drug dependents than alcohol dependents. Also results of this study suggest that among Turkish substance dependents SM might be related to the presence of personality disorder and childhood physical abuse and suicide attempts.     

Self-mutilation in personality disorders: psychological and biological correlates.

OBJECTIVE: The goal of this study was to determine whether self-mutilators with personality disorders differ from nonmutilators with personality disorders in impulsivity, aggression, and other psychopathology and whether serotonergic dysfunction contributes to self-mutilation. METHOD: Twenty-six self-mutilators with personality disorders were matched to 26 control subjects with personality disorders for gender, age, education, axis I diagnosis of affective disorder, and axis II diagnosis of personality disorder. Numerous indexes of psychopathology as well as CSF 5-hydroxyindoleacetic acid (5-HIAA) levels and platelet imipramine binding sites (Bmax) and affinity (Kd) were determined. RESULTS: Self-mutilators had significantly more severe character pathology, had greater lifetime aggression, and were more antisocial than the control subjects. The self-mutilators scored higher on the Hamilton Rating Scale for Depression but not on the Beck Depression Inventory or the Beck Hopelessness Scale. The two groups did not differ on the Buss-Durkee Hostility and Guilt Inventory or on the Sensation Seeking Scale. The degree of self-mutilation was significantly correlated with impulsivity, chronic anger, and somatic anxiety. Both self-mutilation and impulsivity showed significant negative correlations with Bmax, although the two groups did not differ in CSF 5-HIAA levels or in platelet imipramine binding. CONCLUSIONS: The results demonstrate the contribution of severe character pathology, aggression, impulsivity, anxiety, and anger to self-mutilation and provide preliminary support for the hypothesis of underlying serotonergic dysfunction facilitating self-mutilation.     

Research diagnostic criteria (RDC) mental disorder and self-reported symptoms in outpatients with complex partial seizures (CPS)

Fifteen outpatients with complex partial seizures (CPS) were investigated to assess the presence and severity of affective disorders, anxiety, and cognitive deficits. Forty percent of patients met the criteria for an affective disorder according to Research Diagnostic Criteria (RDC). Patients scored significantly higher than controls on the Beck Depression Inventory (p less than 0.001), on the State and Trait Anxiety Inventory (p less than 0.01, p less than 0.05), on the Symptom Questionnaire scales for anxiety (p less than 0.005), depression (p less than 0.01), and somatization (p less than 0.01). They also scored significantly lower than controls on the Mini-Mental State Examination for grading cognitive state (p less than 0.05). Epileptic patients with RDC diagnosis of depression reported significantly more symptoms of depression, anxiety, somatization, and less sociability and trustfulness than epileptic patients without concurrent mental disorders. Implications of these results are discussed.
