The interplay of personality pathology and treatment outcome in psychosomatic psychotherapy: A longitudinal analysis using latent change score modelling.

INTRODUCTION: While ample data demonstrate the effectiveness of inpatient psychosomatic treatment, clinical observation and empirical evidence demonstrate that not all patients benefit equally from established therapeutic methods. Especially patients with a comorbid personality disorder often show reduced therapeutic success compared to other patient groups. Due to the heterogeneous and categorical personality assessment, previous studies indicated no uniform direction of this influence. This complicates the derivation of therapeutic recommendations for mental disorders with comorbid personality pathology. METHODS: Analyzing n = 2094 patients from German university hospitals enrolled in the prospective "MEPP" study, we tested the dynamic interaction between dimensionally assessed personality functioning and psychopathology of anxiety and depression. RESULTS: Longitudinal structural equation modelling replicated the finding that the severity of symptoms at admission predicts symptom improvement within the same symptom domain. In addition, we here report a significant coupling parameter between the baseline level of personality function and the change in general psychopathology - and vice versa. DISCUSSION AND CONCLUSION: These results imply that personality pathology at admission hinders the therapeutic improvement in anxiety and depression, and that improvement of personality pathology is hindered by general psychopathology. Furthermore, the covariance between both domains supports the assumption that personality functioning and general psychopathology cannot be clearly distinguished and adversely influence each other. A dimensional assessment of the personality pathology is therefore recommendable for psychotherapy research and targeted therapeutic treatment.

What Kind of Patients Receive Inpatient and Day-Hospital Treatment in Departments of Psychosomatic Medicine and Psychotherapy in Germany?

INTRODUCTION: Germany is one of the few countries with a medical specialty of psychosomatic medicine and psychotherapy and many treatment resources of this kind. OBJECTIVE: This observational study describes the psychosomatic treatment programs as well as a large sample of day-hospital and inpatients in great detail using structured diagnostic interviews. METHODS: Mental disorders were diagnosed according to ICD-10 and DSM-IV by means of Mini-DIPS and SCID-II. In addition to the case records, a modified version of the CSSRI was employed to collect demographic data and service use. The PHQ-D was used to assess depression, anxiety, and somatization. RESULTS: 2,094 patients from 19 departments participated in the study after giving informed consent. The sample consisted of a high proportion of "complex patients" with high comorbidity of mental and somatic diseases, severe psychopathology, and considerable social and occupational dysfunction including more than 50 days of sick leave per year in half of the sample. The most frequent diagnoses were depression, somatoform and anxiety disorders, eating disorders, personality disorders, and somato-psychic conditions. CONCLUSIONS: Inpatient and day-hospital treatment in German university departments of psychosomatic medicine and psychotherapy is an intensive multimodal treatment for complex patients with high comorbidity and social as well as occupational dysfunction.

Changes of explicitly and implicitly measured self-esteem in the treatment of major depression: evidence for implicit self-esteem compensation.

BACKGROUND AND OBJECTIVES: Self-esteem has been claimed to be an important factor in the development and maintenance of depression. Whereas explicit self-esteem is usually reduced in depressed individuals, studies on implicitly measured self-esteem in depression exhibit a more heterogeneous pattern of results, and the role of implicit self-esteem in depression is still ambiguous. Previous research on implicit self-esteem compensation (ISEC) revealed that implicit self-esteem can mirror processes of self-esteem compensation under conditions that threaten self-esteem. We assume that depressed individuals experience a permanent threat to their selves resulting in enduring processes of ISEC. We hypothesize that ISEC as measured by implicit self-esteem will decrease when individuals recover from depression. METHODS: 45 patients with major depression received an integrative in-patient treatment in the Psychosomatic University Hospital Bonn, Germany. Depression was measured by the depression score of the Hospital Anxiety and Depression Scale (HADS-D). Self-esteem was assessed explicitly using the Rosenberg Self-Esteem Scale (RSES) and implicitly by the Implicit Association Test (IAT) and the Name Letter Test (NLT). RESULTS: As expected for a successful treatment of depression, depression scores declined during the eight weeks of treatment and explicit self-esteem rose. In line with our hypothesis, both measures of implicit self-esteem decreased, indicating reduced processes of ISEC. LIMITATIONS: It still remains unclear, under which conditions there is an overlap of measures of implicit and explicit self-esteem. CONCLUSIONS: The results lend support to the concept of ISEC and demonstrate the relevance of implicit self-esteem and self-esteem compensation for the understanding of depression.

[Evaluation of outpatient psychodynamic psychotherapy: results of a controlled field study ]. / Evaluation ambulanter tiefenpsychologischer Psychotherapie: Ergebnisse einer kontrollierten Feldstudie.

OBJECTIVES: The discussion about the effectivity of psychodynamic psychotherapy is being renewed by recent meta-analyses. Although some well-designed studies have been presented, there is still a dearth of research in this field. METHODS: In a controlled prospective field study we investigated the outcome of outpatient psychodynamic psychotherapy in a pre-post design. This evaluation includes data from the symptom inventories VDS90, VDS30, and HEALTH for 90 patients with different mental disorders before therapy and after the regular end of therapy, compared to a waiting list control group. RESULTS: We found a significant improvement in symptoms, dysfunctional personality features, and quality of life. Rates of statistically and clinically significant improvement were markedly higher after therapy than in the waiting list condition. CONCLUSIONS: Psychodynamic psychotherapy shows an effect on symptoms, dysfunctional personality features, and quality of life.

The multicenter effectiveness study of inpatient and day hospital treatment in departments of psychosomatic medicine and psychotherapy in Germany.

Background: Reliable outcome data of psychosomatic inpatient and day hospital treatment with a focus on psychotherapy are important to strengthen ecological validity by assessing the reality of mental health care in the field. This study aims to evaluate the effectiveness of inpatient and day hospital treatment in German university departments of Psychosomatic Medicine and Psychotherapy in a prospective, naturalistic, multicenter design including structured assessments. Methods: Structured interviews were used to diagnose mental disorders according to ICD-10 and DSM-IV at baseline. Depression, anxiety, somatization, eating disorder and posttraumatic stress disorder (PTSD) symptoms, as well as personality functioning were assessed by means of questionnaires on admission and at discharge. Results: 2,094 patients recruited by 19 participating university hospitals consented to participation in the study. Effect sizes for each of the outcome criteria were calculated for 4-5 sub-groups per outcome domain with differing severity at baseline. Pre-post effect sizes for patients with moderate and high symptom severity at baseline ranged from d = 0.78 to d = 3.61 with symptoms of PTSD, depression, and anxiety showing the largest and somatization as well as personality functioning showing somewhat smaller effects. Conclusions: Inpatient and day hospital treatment in German university departments of Psychosomatic Medicine and Psychotherapy is effective under field conditions.

Can activation of coagulation and impairment of fibrinolysis in patients with anxiety and depression be reversed after improvement of psychiatric symptoms? Results of a pilot study.

Anxiety and depression are associated with an activation of coagulation and impairment of fibrinolysis. This study addresses the question whether these findings are reversed after psychotherapy and improvement of psychiatric symptoms. Three factors of coagulation and fibrinolysis as well as level of anxiety and depression were reassessed in 12 patients 1 to 3 years after intensive inpatient psychotherapy. The patients showed a substantial improvement of their severe anxiety disorder and comorbid depressive disorder. Simultaneously, we found a significant decrease in factor VII and plasminogen activator inhibitor. We conclude that reduction of severe anxiety and depression may be associated with a reversal of the procoagulant effect (activation of coagulation and impairment of fibrinolysis) of these psychological states. Because of the small sample size of this pilot study, further research is needed.

Coagulation activation and fibrinolysis impairment are reduced in patients with anxiety and depression when medicated with serotonergic antidepressants.

AIMS: Anxiety disorders have been shown to be correlated with an activation of coagulation and impairment of fibrinolysis. The aim of the study was to assess whether medication with a serotonergic antidepressant, which has been associated with abnormal bleeding, may modify this effect. METHODS: Thirty-one anxiety patients, mostly with comorbid depression, and 31 healthy controls were included in the study. Group differences between anxiety patients medicated with a serotonergic antidepressant, patients without serotonergic antidepressant and controls were assessed for activated partial thromboplastin time, fibrinogen, factor VII, factor VIII, von Willebrand factor, von Willebrand ristocetin cofactor activity, prothrombin fragment 1 + 2, thrombin-antithrombin complex, d-dimer, α2-antiplasmin, plasmin-α2-antiplasmin complex (PAP), tissue plasminogen activator and plasminogen activator inhibitor. Intervening variables, such as age, sex, body mass index and smoking, were accounted for. RESULTS: We found lower coagulation measures for fibrinogen (P = 0.03) and plasminogen activator inhibitor (P = 0.01), and higher levels of PAP (P = 0.046) in patients with serotonergic antidepressant than in patients without serotonergic antidepressant. When controlling for smoking and body mass index, differences between the two groups were significant for PAP (P = 0.02), von Willebrand ristocetin cofactor activity (P = 0.02) and activated partial thromboplastin time (P = 0.046). Coagulation scores were similar in patients with serotonergic antidepressant to those of healthy controls. CONCLUSIONS: Serotonergic antidepressants may counteract a procoagulant effect of anxiety and/or depression in anxiety patients.

Relative hyperhomocysteinemia in patients with panic disorder: a case-control study.

BACKGROUND: The aim of this work was to examine a possible association between a clinically relevant panic disorder and plasma total homocysteine concentration. METHODS: 23 patients with panic disorder with or without agoraphobia confirmed by a standardized clinical interview (Structural Clinical Interview for DSM-IV-German version) and 23 healthy controls matched for gender and age completed questionnaires (SCL-K9, STAI, ADS, STAXI) and had blood drawn after a 15 min rest. Plasma total homocysteine concentrations were measured by competitive enzyme immunoassay. Interfering variables such as age, gender, smoking status, comorbid depression and medication were controlled for. RESULTS: Patients with panic disorder had higher plasma homocysteine concentrations in comparison to the control group (mean value 11.00 vs. 9.14 mumol/l, p = 0.04 with age, gender, smoking status, comorbid depression and antidepressant medication being controlled for). Furthermore, homocysteine plasma concentration was positively correlated with Global Severity of Symptoms (SCL-K9, r(Pearson) = 0.41, p < 0.01). CONCLUSION: The findings of this study suggest a link between elevated plasma homocysteine levels and panic disorder. This raises a new hypothesis of another pathway to an increased risk of cardiovascular events in anxious individuals.

Alexithymia, temperament and character as predictors of psychopathology in patients with major depression.

The study investigated the capacity of alexithymic personality features, in combination with temperament and character traits, age and gender, to predict psychopathological symptoms in patients with major depression. Consecutive patients (n=339) were investigated using the Toronto Alexithymia Scale-20 (TAS-20), the Temperament and Character Inventory (TCI), the Symptom Checklist-90-R (SCL-90-R), and the Hamilton Depression and Anxiety Rating Scales (HDRS, HARS). The amount of variance in SCL-90-R subscales and Hamilton scales predicted by TAS-20, TCI, age and gender was calculated by linear regression analyses. The 'difficulties identifying feeling' facet of alexithymia appeared to be a significant predictor of all dimensions of psychopathology. Among TCI scales harm avoidance was the strongest predictor for somatization, phobic anxiety, and anxiety (SCL-90-R, HARS); low self-directedness was the strongest predictor for obsessionality, depression (SCL-90-R, HDRS), interpersonal sensitivity and psychoticism; and low cooperativeness was the strongest predictor for hostility and paranoia. In conclusion, many psychopathological symptoms in major depression are associated with difficulties in the identification of emotions. Relative to alexithymia, Cloninger's psychobiological model of personality could predict psychopathological symptoms in a distinct and meaningful manner. The TAS-20 and the TCI are useful questionnaires for a better understanding of the relationship between psychopathology and personality in major depression.

Temperament and character personality profile in relation to suicidal ideation and suicide attempts in major depressed patients.

To prevent suicidal behaviour, it is important to better understand those personality traits associated with suicidal ideation and suicide attempts. A sample of 394 consecutive major depressed outpatients admitted to Bonn University Hospital was subdivided into three groups: Lifetime suicide attempters (N=32; 8.1%), suicide ideators (N=133) and patients without suicide ideation (N=229). Psychodiagnostic measures embraced the Temperament and Character Inventory (TCI), the Symptom Checklist-90-R and the Hamilton Depression Rating Scale. Suicide attempters and ideators showed higher scores on emotional distress and depression. Analysis of covariance (covariates: age, gender, depression) revealed that suicide attempters score higher on the temperament dimension harm avoidance compared with non-attempters. Suicide ideators could be distinguished from non-ideators by character dimensions in terms of lower self-directedness and higher self-transcendence. Our findings suggest that high harm avoidance is a personality trait associated with suicide attempt in major depression, whereas low self-directedness and high self-transcendence are related to suicidal ideation. As temperament dimensions represent the "emotional core" and character dimensions the "cognitive core" of personality, we discuss whether Cloninger's psychobiological model might be helpful to distinguish between non-suicide ideators, patients who do think about suicide, and patients initiating suicidal behaviour.

Association between anxiety and factors of coagulation and fibrinolysis.

BACKGROUND: Psychological stress and anxiety have been shown to produce an activation of coagulation and fibrinolysis. Resulting hypercoagulability is a risk factor for cardiovascular diseases, and could therefore contribute to an increased prevalence of coronary artery disease in anxiety patients. However, hemostasis function has not yet been studied in patients with clinically relevant anxiety disorders. METHODS: A group of anxiety patients (panic disorder with agoraphobia or social phobia) and a healthy control group (each n = 29) completed some questionnaires [SCL-K9 (a short form of the SCL-90-R), State Trait Anxiety Inventory, ADS (general depression scale)], and had blood drawn after a 15-min rest period. To assess the reaction of the hemostatic system by global entities, sum scores were computed from parameters of coagulation and fibrinolysis (fibrinogen, FVII, FVIII, vWF, F1 + 2, TAT, D-dimer, alpha(2)-AP, PAP, tPA, PAI-1). Interfering variables, such as age, gender, alcohol consumption and smoking status, were controlled. RESULTS: Anxiety patients scored higher in a composite hemostatic score and a sum score of fibrinolysis in comparison to the control group, with a predominant activation of inhibitors in fibrinolysis. However, the psychological variable with the closest association to hemostasis was not trait anxiety, but self-perceived worry about blood drawing before blood sampling was performed. CONCLUSIONS: The coagulation and fibrinolysis system is activated in the direction of a hypercoagulable state in patients with severe phobic anxiety, triggered by fear of blood drawing. This could be one mediating factor for the increased risk of cardiovascular diseases in this population. Acute situational phobic anxiety should be monitored closely when studying the association between anxiety and hemostasis.

Nature against nurture: calcification in the right thalamus in a young man with anorexia nervosa and obsessive-compulsive personality disorder.

This report describes the case of a young man with a large calcification in the right thalamus that was first diagnosed at 9 years of age. Case history reveals specific eating rituals and other obsessive-compulsive personality traits during the patient's childhood and adolescence, fulfilling diagnostic criteria of obsessive-compulsive personality disorder. After a critical life event the patient develops anorexia nervosa. We suggest that our case and further literature provide evidence for an involvement of specific thalamic structures, such as the dorsomedial nucleus, in the development of anorexia nervosa. Furthermore, the treatment of the patient by a combined psychotherapeutic and pharmacotherapeutic approach is described. We focus on the beneficial effect of the atypical antipsychotic olanzapine, which can induce weight gain by an increase of leptin levels.

Evidence for attenuated affective processing in obesity.

Attenuated affective processing is hypothesized to play a role in the development and maintenance of obesity. Using an affective priming task measuring automatic affective processing of verbal stimuli, a group of 30 obese participants in a weight-loss program at the Psychosomatic University Clinic Bonn (M age = 48.3, SD = 10.7) was compared with a group of 25 participants of normal weight (M age = 43.6, SD = 12.5). A smaller affective priming effect was observed for participants with obesity, indicating less pronounced reactions to valenced adjectives. The generally reduced affective processing in obese participants was discussed as a possible factor in the etiology of obesity. Individuals who generally show less pronounced affective reactions to a given stimulus may also react with less negative affect when confronted with weight gain or less positive affect when weight is lost. Consequently, they could be expected to be less motivated to stop overeating or to engage in dieting and will have a higher risk of becoming or staying obese.

Psychophysiological decoupling in alexithymic pain disorder patients.

Considering that impaired coping with stress is closely linked with emergence of stress-sensitive disorders most notably in alexithymic individuals, we conducted the first study examining stress-related autonomic reactivity in alexithymic pain disorder patients. Twenty-one pain disorder patients with high and an equivalent patient group with low alexithymia scores were exposed to three types of affect-inductive stimuli with variable affective involvement: arithmetic task, watching arousing video material and giving an oral presentation. Subjective appraisal of the induced emotional experience and physiological reactivity (heart rate, muscle tension and skin conductance) was documented. During oral presentation high alexithymia patients showed significantly lower skin conductance in combination with increased subjective negative affect compared to low alexithymia patients. Our results thus demonstrate a decoupling between physiological and affect processing in pain disorder patients with high alexithymia during a stressful situation that was subjectively associated with negative affect.

The German Version of the Herth Hope Index (HHI-D): Development and Psychometric Properties.

BACKGROUND: The importance of hope is evident in clinical oncological care. Hope is associated with psychological and also physical functioning. However, there is still a dearth of empirical research on hope as a multidimensional concept. The Herth Hope Index is a reliable and valid instrument for the measurement of hope and is available in many languages. Until now no authorized German translation has been published and validated. METHODS: After translation, the questionnaire was completed by 192 patients with different tumor entities in radiation therapy. Reliability, concurrent validity, and factor structure of the questionnaire were determined. RESULTS: Correlations were high with depression and anxiety as well as optimism and pessimism. As expected, correlations with coping styles were moderate. Internal consistency and test-retest reliability were satisfactory. We could not replicate the original 3-factor model. Application of the scree plot criterion in an exploratory factor analysis resulted in a single-factor structure. CONCLUSIONS: The Herth Hope Index - German Version (HHI-D) is a short, reliable, and valid instrument for the assessment of hope in patient populations. We recommend using only the HHI-D total score until further research gives more insights into possible factorial solutions and subscales.

Factorial structure of the 20-item Toronto Alexithymia Scale in a large sample of somatoform patients.

Although a strong association between alexithymia and somatization has been postulated in numerous studies, no systematic study has investigated the psychometric properties of the 20-item Toronto Alexithymia Scale (TAS-20) in a sample of patients with somatoform disorder yet. The purpose of this study was to ensure a valid assessment by the German version of the TAS-20 in somatoform samples. We investigated whether the original three-factor model proposed by Bagby et al. (1994a), which is widely used in clinical research and practice, is replicable in a large sample of somatoform patients (n=806). Using confirmatory factor analysis (CFA) the goodness-of-fit of the originally proposed factor structure was compared to three factor models generated with exploratory factor analysis (EFA) and other factorial solutions derived from the literature. Our results demonstrate that the original three-factor model is not replicable in somatoform patients. Instead, the four-factor model by Franz et al. (2001b) described the data best. However, none of the models met all criteria of confirmatory factor analysis. Our results indicate that the three-factor model is not robust in the German version of the TAS-20. At this state of research we recommend to use the TAS-20 sum-score as a measure of alexithymia in somatoform patients in clinical practice.

Childhood adversities in patients with fibromyalgia and somatoform pain disorder.

Primary fibromyalgia is regarded as disorder with a complex symptomatology, and no morphological alterations. Findings increasingly point to a dysfunction of the central nervous pain processing. The study aims to discuss vulnerability for fibromyalgia from a developmental psychopathological perspective. We investigated the presence of psychosocial adversities affecting the childhood of adult fibromyalgia patients (FM) and compared them to those of patients with somatoform pain disorders (SOM) and a control group (CG) with medically explained chronic pain. Using the structured biographical interview for pain patients (SBI-P), 38 FM patients, 71 SOM patients, and 44 CG patients were compared on the basis of 14 childhood adversities verified as relevant regarding longterm effects for adult health by prospective studies. The FM patients show the highest score of childhood adversities. In addition to sexual and physical maltreatment, the FM patients more frequently reported a poor emotional relationship with both parents, a lack of physical affection, experiences of the parents' physical quarrels, as well as alcohol or other problems of addiction in the mother, separation, and a poor financial situation before the age of 7. These experiences were found to a similar extent in the SOM patients, but distinctly less frequently in the CG. The results point to early psychosocial adversities as holding a similar etiological meaning in fibromyalgia as well as in somatoform pain disorders. The potential role of these factors as increasing the vulnerability for fibromyalgia is discussed.

[Impact of an additional behavioral anxiety intervention on therapy outcome in a psychodynamic inpatient setting]. / Verbessert die zusätzliche Durchführung einer verhaltenstherapeutischen Intervention die Ergebnisse stationärer psychodynamischer Therapie bei Panikstörung/Agoraphobie?

This naturalistic study aimed at evaluating the implementation of an additional symptom-oriented intervention program for patients with panic disorder and/or agoraphobia in a psychodynamic inpatient setting. Patients receiving this intervention showed a significantly better therapy outcome as measured by the symptom-specific scales of the SCL-90-R compared to anxiety patients who had not undergone this additional treatment. This specific improvement was stronger than the general improvement found in therapy outcome over time. Our findings show that the combination of different treatment strategies in one setting may prove effective. However, some problems are discussed which may emerge in clinical practice.

Patients with obesity show reduced memory for others' body shape.

Social comparison theory assumes that individuals regularly compare themselves to others and that the comparisons are relevant for their self-esteem. For individuals with obesity, these social comparisons will yield a negative outcome with respect to body shape in the majority of social contacts. It is proposed that, when confronted with other persons, individuals with obesity avoid social comparisons on the dimension of body shape. Using a multinomial account of social categorization, 19 female psychotherapy patients with morbid obesity were compared to 19 non-obese female psychotherapy patients. As predicted, results reveal reduced memory for body shape categories in patients with obesity, indicating a reduced processing of body shape information.

Temperament and character personality profiles and personality disorders in chronic pain patients.

In his psychobiological model of personality, Cloninger developed a novel approach concerning the relationships between psychopathological syndromes and personality. We investigated 207 chronic pain patients (CPPs) and compared them to 105 pain-free control subjects. Participants were assessed using the Temperament and Character Inventory (TCI), the Structured-Clinical-Interview-II, the Beck Depression Inventory and the Spielberger Anxiety Inventory. The CPPs scored higher on the depression and state anxiety scales and 41% fulfilled the criteria of having at least one personality disorder (PD). We used a covariance analysis to control for depression and state anxiety and found that the CPPs scored higher on the Harm Avoidance Temperament Dimension and lower on the Self-Directedness and Cooperativeness Character Dimensions. In CPPs, the symptom counts of all PD subtypes were significantly related to low Self-Directedness and, to a lesser degree, low Cooperativeness. The PD symptoms in Cluster A were related to low Reward Dependence, those in Cluster B were related to high Novelty Seeking and the PD symptoms in Cluster C were related to high Harm Avoidance. In multiple hierarchical regression analyses, controlling for age, gender, depression and state anxiety, TCI scales predicted on average 23% in PD symptom counts. The Self-Directedness and Cooperativeness personality traits appeared to be significant predictors in determining the presence or absence of a PD by correctly classifying 75.8% of CPPs. The TCI provides further insight into the mechanisms underlying the development of chronic pain. This useful diagnostic instrument helps to economically and validly facilitate the identification of core PD features.
