Relationship between perfectionism,personality disorders and agoraphobia in patients with panic disorder

OBJECTIVE: In earlier reports, we found that perfectionism might be involved in the development and/or maintenance of agoraphobia in panic disorder. The present report extends this work by examining the relationship between perfectionism and comorbidity with personality disorders in panic disorder patients with agoraphobia (PDA) and those without agoraphobia (PD). METHOD: We examined comorbidity of personality disorders by Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) and assessed perfectionism using multidimensional perfectionism scale in 56 PDA and 42 PD patients. RESULTS: The PDA group met criteria for at least one personality disorder significantly more often than the PD group. With stepwise regression analyses, avoidant and obsessive-compulsive personality disorders emerged as significant indicators of perfectionism in patients with panic disorder. CONCLUSION: These findings suggest that perfectionism in panic disorder patients may be more common in those with comorbid personality disorders, and may be an important target for preventive and therapeutic efforts.     

DSM-III-R Axis I and II disorders in agoraphobic patients with and without panic disorder

Patients attending an inpatient phobia treatment program were diagnosed for DSM-III-R Axis I and II disorders, using the Structured Clinical Interview for DSM-III-R Disorders, and completed a set of self-report instruments. They were divided into 3 groups: (a) those who met the criteria for panic disorder with agoraphobia (n= 57), (b) those who met the criteria for agoraphobia without a history of panic disorder (n= 21), and (c) those who met criteria for other anxiety disorders, but not for panic/agoraphobia (n= 14). On Axis I, more of the panic with agoraphobia than of the agoraphobia without panic patients had obsessive-compulsive disorder. On Axis II, no significant differences between the agoraphobic patients with and without panic occurred. However, the number of hysterical traits was related to the presence of panic disorder among the agoraphobic patients. Avoidant and dependent traits were related to symptom severity.     

Personality disorder comorbidity in panic disorder patients with or without current major depression

To investigate the relationship between current or past major depressive disorder (MDD) on comorbid personality disorders in patients with panic disorder, we compared the comorbidity of personality disorders using the Structured Clinical Interview for DSM-III-R personality disorders (SCID-II) in 34 panic disorder patients with current MDD (current-MD group), 21 with a history of MDD but not current MDD (past-MD group), and 32 without lifetime MDD comorbidity (non-MD group). With regard to personality disorders, patients in the current-MD group met criteria for at least one personality disorder significantly more often than patients in the past-MD group or the non-MD group (82.4% vs. 52.4% and 56.3%, respectively). The current-MD group showed statistically significantly more borderline, dependent, and obsessive-compulsive personality disorders than the past-MD group or non-MD group. With stepwise regression analyses, number of MDD episodes emerged as an indicator of the comorbidity of cluster C personality disorder and any personality disorders. Future studies should determine whether aggressive treatment of comorbid personality disorders improves the outcome (e.g., lowers the likelihood of comorbid MDD) of patients with panic disorder.     

Psychoticism in patients with panic disorder with or without comorbid agoraphobia

Objective: A few case-reports have previously described transient psychotic-like symptoms in non-psychotic patients with panic disorder (PD). We aimed to systematically explore whether PD patients without any current or past psychosis can be differentiated according to the severity of ‘psychoticism’ as a dimension, comprising clinical features such as psychotic-like experiences, increased social alienation, hostility and suspiciousness.

Methods: Sample included 35 (female?=?26) medication-free, non-psychotic patients consecutively referred from our Department’s Outpatient Clinic for acute symptoms of DSM-5 PD with (PDA; N?=?29) or without concurrent agoraphobia. Psychometric measures included the Symptom Checklist–90–Revised (SCL-90-R), Agoraphobic Cognitions Questionnaire (ACQ), Body Sensations Questionnaire (BSQ), and panic attacks during last 21 days PA-21d.

Results: Multiple regression analysis (forward stepwise) revealed that, among all SCL-90-R subscales, the psychoticism-subscale was most significantly associated with panic-related beliefs included in the ACQ, while significant associations emerged between the paranoid ideation-subscale and the ACQ and BSQ measures. Moreover, significant correlations emerged between the SCL-90-R psychoticism-subscale and all three measures of PD symptoms (ACQ, BSQ, PA-21d) and between the SCL-90-R paranoid ideation-subscale and both the ACQ and BSQ.

Conclusions: This significant association between levels of psychoticism and severity of panic symptoms may reflect a more severe subtype of PD.     

Personality disorders and relationship to personality dimensions measured by the Temperament and Character Inventory in patients with obsessive-compulsive disorder

The occurrence of personality disorders was investigated in 36 patients with obsessive-compulsive disorder by means of the SCID Screen questionnaire. In addition, the personality dimensions were explored by means of the Temperament and Character Inventory (TCI). In total, 75% of the patients fulfilled the criteria for a personality disorder according to the SCID Screen questionnaire, mostly (55%) within cluster C. Several significant correlations were found between the separate personality disorders (PD) and subscales of the TCI, the most pronounced being between avoidant and obsessive-compulsive PD and novelty-seeking and self-directedness. Strong correlations were also found between self-directedness and paranoid and borderline PD. In multiple regressions where the presence of PD in clusters A, B and C, respectively, were used as dependent variables and where the separate subscales of the TCI were used as independent variables, the multiple R reached 0.68, 0.76 and 0.80 in clusters A, B and C, respectively. Thus 46–64% of the variance in the personality disorder clusters could be explained by the TCI subscales.     

Morbidity of comorbid psychiatric diagnoses in the clinical presentation of panic disorder

This study seeks to determine how panic disorder patients with anxiety and depression comorbidity differ from panic disorder patients without comorbidity at the time of presentation for treatment. One-hundred seventy-one panic disorder patients presenting for their initial assessment and treatment at the Payne Whitney Anxiety Disorders Clinic agreed to participate and completed self-report and diagnostic assessments. Sixty-seven percent of panic disorder subjects were found to have at least one comorbid anxiety or depression diagnosis. Age and gender ratio were not affected by the presence of comorbid diagnoses. Comorbidity significantly contributed to psychological distress and symptom load, overall impairment, and interpersonal impairment.     

Clinical differentiation between major depression only, major depression with panic disorder and panic disorder only. Childhood, personality and personality disorder

A consecutive sample of 298 nonpsychotic psychiatric outpatients was classified according to DSM-III and divided into 4 diagnostic groups: pure major depression, mixed major depression/panic disorder, pure panic disorder and a remaining group of other disorders. The patients' report of childhood relationship to parents and siblings, family atmosphere, their own personality characteristics as children and precipitating events were compared in the various groups. In addition, differences in personality and frequencies of personality disorders were investigated by means of various instruments. Our results show that the type of relationship to parents in childhood differed in the various groups. The mother seems to be the most crucial person for the development of depression, the father for the development of panic disorder. Patients with major depression are more obsessive and patients with panic disorder more infantile and avoidant with less control of their personality. Finally, patients with mixed conditions are more in accordance with the DSM-III anxious personality disorder cluster.     

Obsessive-compulsive disorder comorbid with borderline personality disorder: A long-term case study

Abstract Three case reports of patients with borderline personality disorder (BPD) and obsessive-compulsive disorder (OCD) for more than 10 years are used to illustrate the relationship between OCD and borderline pathology. The recognizable features of the obsessive-compulsive symptoms in these reports are: (i) pervasiveness, the symptomatic overlap of obsessive-compulsive symptoms; (ii) poor insight and resistance; and (iii) obsessive control evident in personal relationships. These features are manifestations of OCD psychopathology as well as of a personality disorder. The symptoms with these features are located hypothetically towards the severe end of the symptomatic spectrum of OCD. The comorbidity is not a simple relationship, and the symptomatology of the comorbid patient is derived from OCD pathology linked with the personality disorder rather than from independent BPD pathology.     

Bipolar obsessive-compulsive disorder and personality disorders

OBJECTIVES: Relatively few systematic data exist on the clinical impact of bipolar comorbidity in obsessive-compulsive disorder (OCD) and no studies have investigated the influence of such a comorbidity on the prevalence and pattern of Axis II comorbidity. The aim of the present study was to explore the comorbidity of personality disorders in a group of patients with OCD and comorbid bipolar disorder (BD). METHODS: The sample consisted of 204 subjects with a principal diagnosis of OCD (DSM-IV) and a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score>or=16 recruited from all patients consecutively referred to the Anxiety and Mood Disorders Unit, Department of Neuroscience, University of Turin over a period of 5 years (January 1998-December 2002). Diagnostic evaluation and Axis I comorbidities were collected by means of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Personality status was assessed by using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II). Socio-demographic and clinical features (including Axis II comorbidities) were compared between OCD patients with and without a lifetime comorbidity of BD. RESULTS: A total of 21 patients with OCD (10.3%) met DSM-IV criteria for a lifetime BD diagnosis: 4 (2.0%) with BD type I and 17 (8.3%) with BD type II. Those without a BD diagnosis showed significantly higher rates of male gender, sexual and hoarding obsessions, repeating compulsions and lifetime comorbid substance use disorders, when compared with patients with BD/OCD. With regard to personality disorders, those with BD/OCD showed higher prevalence rates of Cluster A (42.9% versus 21.3%; p=0.027) and Cluster B (57.1% versus 29.0%; p=0.009) personality disorders. Narcissistic and antisocial personality disorders were more frequent in BD/OCD. CONCLUSIONS: Our results point towards clinically relevant effects of comorbid BD on the personality profiles of OCD patients, with higher rates of narcissistic and antisocial personality disorders in BD/OCD patients.     

Temperament features in adolescents with ego-syntonic or ego-dystonic obsessive-compulsive symptoms

The present study evaluated whether different patterns of temperament may predict a different threshold of acceptability of obsessive-compulsive (OC) symptoms in adolescents. OC symptomatology was detected with the Leyton Obsessional Inventory-Child Version (LOI-CV) and temperament was assessed using the tridimensional personality questionnaire in 2,775 high-school students. According to the LOI-CV scores, the adolescents were classified as high interference (interfering, ego-dystonic symptoms) (HI), supernormal (noninterfering, ego-syntonic symptoms) (Sn) and controls (C) HI were 119 (4.3%), Sn 85 (3.1%) and C 2,571 (92.6%). The best predictor of belonging to HI or Sn groups was the temperament configuration of high Harm Avoidance (HA) and high Persistence (P). The feature that mainly distinguishes the two symptomatic groups were Novelty Seeking (NS) levels. Our data suggest that people characterized by pessimistic worry in anticipation of future problems, passive avoidant behaviour, rapid fatigability (high HA) and irresoluteness, ambitiousness, perseverance, perfectionism, enduring feelings of frustration (high P) might develop OC symptoms. Whether OC symptoms become ego-syntonic or ego-dystonic seems to mainly depend on NS levels: low NS might protect people (with the prevention of “exploratory and active behaviours” that may elicit loss of control on symptoms) from the development of interfering OC symptoms.     

Frequency of panic attacks and panic disorder in adolescents

By using data from the Bremer Adolescent Study, this report presents findings on the frequency, comorbidity, and psychosocial impairment of panic disorder and panic attacks among 1,035 adolescents. The adolescents were randomly selected from 36 schools in the province of Bremen, Germany. Panic disorder and other psychiatric disorders were coded based on DSM-IV criteria using the computerized-assisted personal interview of the Munich version of the Composite International Diagnostic Interview. Panic disorder occurred rather rare, with only 0.5% of all the adolescents met the DSM-IV criteria for this disorder sometimes in their live. Panic attack occurred more frequently, with 18% of the adolescents reported having had at least one panic attack. Slightly more girls than boys had panic attack and panic disorder. The occurrence of panic attack and panic disorder were the greatest among the 14–15 year olds. The experience of having a panic attack was associated with a number of problems, the most frequent being avoiding the situation for fear of having another attack. Four most common symptoms associated with a panic attack were that of palpitations, trembling/shaking, nausea or abdominal distress, and chills or hot flushes. Panic disorder comorbid highly with other psychiatric disorders covered in our study, especially with that of major depression. Among those with a panic disorder, about 40% of them were severely impaired during the worst episode of their illness. Only one out of five adolescents with panic disorder sought professional help for emotional and psychiatric problems. The implication of our findings for research and clinical practice are discussed.

A family study of anxiety disorders: familial transmission and relationship to mood disorder and psychoactive substance use disorder

The prevalence of mental disorders in 76 first-degree relatives (parents and nontwin siblings) of 33 subjects with anxiety disorder was compared with the prevalence of mental disorders in 45 first-degree relatives of 20 subjects with mood disorder and 13 first-degree relatives of 6 subjects with psychoactive substance use disorder. All subjects were personally interviewed with the Structured Clinical Interview for DSM-III-R Axis I (SCID I). Interrater reliability was high for most diagnoses. Significantly more first-degree relatives of subjects with anxiety disorder had panic disorder and generalized anxiety disorder compared with relatives of probands with mood disorder. Significantly more female than male relatives of anxiety subjects suffered from anxiety disorders; there were no gender differences in the prevalence of anxiety disorders in relatives of mood and psychoactive substance use disorder (PSUD) subjects. The combination of anxiety and mood disorder was overrepresented in first-degree relatives of subjects with the same type of comorbidity. In relatives of subjects with mixed anxiety and psychoactive substance use disorder, but no mood disorder, there was an overrepresentation of PSUD; mainly alcohol abuse or dependence.     

A preliminary investigation of the effects of cognitive behavioral therapy for panic disorder on gastrointestinal distress in patients with comorbid panic disorder and irritable bowel syndrome

Background: High comorbidity between panic disorder with/without agoraphobia (PD/A) and irritable bowel syndrome (IBS) has been identified in the literature. These findings have resulted in the recent development of neurobiological models to explain their overlapping symptoms and related origins. This study was a preliminary investigation of the influence of cognitive behavioral therapy (CBT) for PD/A on PD/A patients with and without comorbid IBS. Methods: All patients completed a thorough intake assessment, brief waitlist period, and a 12‐week CBT group for PD/A. Results: The results demonstrated significant reductions in the symptoms of anxiety, depression, and overall impairment in both patient groups (ts>2.3; Ps<.05). In addition, PD/A patients with comorbid IBS also experienced reductions in the disability and distress associated with their gastrointestinal symptoms of IBS (ts>1.9; Ps<.07). Conclusions: Although additional research still is needed, these preliminary findings suggest that CBT for PD/A can be used to simultaneously treat comorbid symptoms of PD/A and IBS. Implications for the neurobiological models for these comorbid conditions were discussed. Depression and Anxiety, 2011. © 2011 Wiley Periodicals, Inc.     

Alcoholism and panic disorder: is the comorbidity more than coincidence?

Studies on alcoholic patients have found a higher than expected prevalence of panic disorder, and suggest a positive correlation between the level of alcohol consumption and severity of anxiety. Conversely, there is an increased prevalence of alcoholism among patients with panic disorder and their blood relatives. A comparison of symptoms, physiological and neurochemical changes known to occur in both alcohol withdrawal and panic disorder reveals a degree of similarity between the 2 conditions. Based on the data, we propose that the chemical and cognitive changes occurring as the result of repeated alcohol withdrawals may kindle and condition coincidence of panic attacks in susceptible individuals. Implications of our postulates for treatment of alcohol withdrawal and panic disorder in alcoholics and for future studies are discussed.     

Clinical characteristics of unipolar disorder and bipolar disorder according to the lifetime presence of recurrent panic attacks

Objectives:  The frequent comorbidity of panic and affective disorders has been described in previous studies. However, it is not clear how panic disorder comorbidity in unipolar disorder and bipolar disorder is related to illness course.
Methods:  We compared lifetime clinical characteristics of illness and items of symptomatology in samples of individuals with bipolar I disorder (n = 290) and unipolar disorder (n = 335) according to the lifetime presence of recurrent panic attacks.
Results:  We found significant differences in clinical course of illness characteristics that were shared across the unipolar and bipolar samples according to the lifetime presence of panic attacks. We also found a number of differences according to the presence of panic attacks that may be specific to the diagnostic group.
Conclusions:  Distinguishing patients who have mood disorder diagnoses, especially bipolar I disorder, according to the lifetime presence of panic attacks may not only be of use in clinical practice, but may also be informative for aetiological research, such as molecular genetic studies.     

The effect of temperament and character on response to selective serotonin reuptake inhibitors in panic disorder

OBJECTIVE: In this prospective study, temperament and character were evaluated in patients with panic disorder (PD), before 1 year of medication therapy, to verify whether these factors influenced the outcome of treatment. METHOD: Seventy-one PD patients were evaluated with the SCID-IV, the Temperament and Character Inventory (TCI), the SCL-90, the Ham-A and the Ham-D. Patients were treated with pharmacotherapy and were evaluated monthly over 1 year. RESULTS: Before treatment, non-remitted patients showed higher levels of harm avoidance (HA) and lower levels of persistence (P), self-directedness (SD) and cooperativeness (C), whereas remitted patients showed only higher levels of HA. After controlling the effect of the confounding variables, the likelihood to achieve remission was positively related to SD score (OR = 1.12; P = 0.002), particularly 'self-acceptance' SD dimension (OR = 1.30; P = 0.02). CONCLUSIONS: Our data suggest that in PD: i) the evaluation of personality, using the Cloninger's model, confirms the presence of personality pathology as one predictor of non-response to treatment; ii) in patients with low SD a combination of medication and cognitive-behaviour therapy should be the most effective treatment.
