Unerwünschte Gedanken bei Angststörungen / Diagnostik und experimentelle Befunde

Fehm, Lydia Birgit 25 June 2000 (has links) (PDF)
Die vorliegende Arbeit beschäftigt sich mit der Diagnostik unerwünschter Gedanken sowie der Spezifität von Gedankenunterdrückung bei phobischen Patienten. Zwei Fragebogenverfahren zum Thema Sorgen sowie ein Instrument zur Erfassung von Strategien im Umgang mit intrusiven Gedanken wurden bezüglich der Gütekriterien der deutschen Übersetzung in einer klinischen Stichprobe evaluiert. Dabei handelt es sich um den Worry Domains Questionnaire (WDQ), der Sorgeninhalte erhebt, den Penn State Worry Questionnaire (PSWQ), der die Intensität von Sorgen erfasst, und den Thought Control Questionnaire (TCQ) zur Erfassung der Gedankenkontrollstrategien. Die Verfahren wurden bei 440 Psychotherapie-Patienten zu drei Meßzeitpunkten eingesetzt. Hinsichtlich der inneren Konsistenz und der Retest-Reliabilität ergeben sich für alle Instrumente zufriedenstellende bis gute Kennwerte. Die Validität ist nur für den PSWQ als gut zu bezeichnen. Beim WDQ zeigen sich Probleme hinsichtlich der Trennung von Sorgen und sozialer Ängstlichkeit, während der TCQ wohl eher Aspekte allgemeiner Psychopathologie als spezifische Strategien erfasst. Eine zweite Studie befasste sich mit intentionaler Gedankenunterdrückung. Die paradoxen Effekte dieser Bemühungen wurden wiederholt mit psychischen Störungen, vor allem mit Angststörungen, in Verbindung gebracht. Dabei ist ein wichtiges Thema, ob die Gedankenkontrollfähigkeit nur für störungsspezifische Inhalte oder generell beeinträchtigt ist. Die vorliegende Studie verglich Patienten mit Agoraphobie und Patienten mit Sozialphobie mit einer gesunden Kontrollgruppe. Alle Personen mussten Gedanken an ein neutrales Kontrollthema sowie zwei störungsspezifische Themen unterdrücken. Es zeigte sich ein störungsspezifischer Effekt bei den Agoraphobikern. Sozialphobiker scheinen hingegen ein generelles Defizit ihrer mentalen Kontrolle aufzuweisen. Zusätzlich erwies sich soziale Ängstlickeit innerhalb einer Reihe psychopathologischer Variablen als stärkster Prädikator für Schwierigkeiten bei der Gedankenunterdrückung. Ingesamt weisen einige Ergebnisse dieser Arbeit darauf hin, dass Gedankenunterdrückung ein wichtiges Merkmal der Sozialphobie sein könnte. / The work conducted aimed at evaluating instruments investigating unwanted thoughts as well as determining the specifity of thought suppression in phobia. German translations of two questionnaires measuring worry as well as an instrument, measuring strategies used in dealing with unwanted thoughts, were evaluated in a clinical sample. We used the Worry Domains Questionnaire (WDQ), measuring contents of worry, the Penn State Worry Questionnaire (PSWQ), measuring the intensity of worry, and the Thought Control Questionnaire (TCQ), investigating strategies in thought control. The instruments were administered at three points in a sample of 440 patients receiving psychological treatment. Concerning internal consistency and retest-reliability all questionnaires showed acceptable to good results. Validity is only good concerning PSWQ. WDQ has problems in differentiating worry and social anxiety, where as TCQ seems to measure general psychopathology more than specific strategies. The second study investigated intended thought suppression. Its paradoxical effects have been linked to psychological disorders, namely anxiety disorders. One important issue is if thought suppression is impaired only for thoughts related to the disorder or if the ability for mental control is generally impaired in anxiety patients. This study compared groups of agoraphobics and social phobics with healthy controls. All subjects had to suppress a neutral topic and two topics related to the central fear of the two disorders. We found a rather specific deficit in thought suppression for the agoraphobics. Social phobics seem to be characterized by a general impairment of mental control. In addition, among several psychopathological variables, social anxiety proved to be the strongest predictor for problems with thought suppression. Taken together, there are several indicators that thought suppression may be an important feature of social phobia.

The short- and long-term effect of duloxetine on painful physical symptoms in patients with generalized anxiety disorder: Results from three clinical trials

Beesdo, Katja, Hartford, James, Russell, James, Spann, Melissa, Ball, Susan, Wittchen, Hans-Ulrich 23 April 2013 (has links) (PDF)
Generalized anxiety disorder (GAD) is associated with painful physical symptoms (PPS). These post hoc analyses of previous trial data assessed PPS and their response to duloxetine treatment in GAD patients. Studies 1 and 2 (n = 840) were 9- to 10-week efficacy trials; study 3 (n = 887) was a relapse prevention trial comprising a 26-week open-label treatment phase and a 26-week double-blind, placebo-controlled treatment continuation phase. Mean baseline visual analog scale scores (VAS, 0–100; n = 1727) ranged from 26 to 37 for overall pain, headache, back pain, shoulder pain, interference with daily activities, and time in pain while awake. In studies 1 and 2, improvement on all VAS scores was greater in duloxetine-treated than in placebo-treated patients (p ≤ 0.01). In study 3, pain symptoms worsened in responders switched to placebo compared with those maintained on duloxetine (p ≤ 0.02). In conclusion, duloxetine was efficacious in the short- and long-term treatment of PPS, which are common in GAD patients.

A striking pattern of cortisol non-responsiveness to psychosocial stress in patients with panic disorder with concurrent normal cortisol awakening responses

Petrowski, Katja, Herold, Ulf, Joraschky, Peter, Wittchen, Hans-Ulrich, Kirschbaum, Clemens 23 April 2013 (has links) (PDF)
Background: Subtle and inconsistent differences in hypothalamic-pituitary-adrenal (HPA) axis activity have been reported for patients with panic disorder. While these patients show little or no alterations in basal ACTH and cortisol levels, it has been hypothesized that HPA hyperresponsivity was a trait in panic patients when exposed to novel and uncontrollable stimulation. Methods: Thirty-four patients (23 females, mean age 35 yrs) diagnosed with panic disorder were compared to 34 healthy controls matched for age, gender, smoking status, and use of oral contraceptives. Both groups were exposed twice to a potent laboratory stress protocol, the Trier Social Stress Test (TSST) on consecutive days. Free salivary cortisol levels and heart rate responses were repeatedly measured before and following the TSST. In addition, the cortisol awakening response (CAR) was assessed to further investigate HPA reactivity in PD patients. Results: While the TSST induced similar heart rate stress responses in both groups, cortisol responses were clearly absent in the panic patients with normal responses in the controls (F(1.96, 66) = 20.16; p < 0.001). No differences in basal cortisol levels were observed in the extended baseline period. The same cortisol stress non-response patterns were observed when patients with/without comorbid depression, or with/without psychotropic medication were compared. In contrast to their non-response to the psychosocial stressor, panic patients showed a significant CAR. Conclusion: These findings provide strong evidence to suggest that PD patients present with a striking lack of cortisol responsivity to acute uncontrollable psychosocial stress under laboratory conditions. This unresponsiveness of the HPA axis appears to be rather specific, since a normal CAR in the morning could be documented in these patients. Thus, the present results do not support the hypothesis that PD patients show a trait HPA hyperresponsiveness to novel and uncontrollable stimulation. In contrast, the data provide support for a hyporesponsive HPA axis under emotional stress in PD patients.

Wie wirksam ist das Fortbildungsprogramm "Patientenseminar Angst"? Ein erster Erfahrungsbericht / How Effective Is the Patientseminar 'Anxiety'?

Perkonigg, Axel, Wittchen, Hans-Ulrich 03 December 2012 (has links) (PDF)
Der folgende Beitrag schildert erste Ergebnisse einer Evaluationsstudie des Fortbildungsprogramms «Patientenseminar Angst» für Ärzte. 109 Teilnehmer der Veranstaltung I und 104 Teilnehmer der Veranstaltung II wurden vor und im Anschluβ an die Veranstaltungen sowie 3 Monate später bezüglich ihrer Beurteilung des Fortbildungsprogramms sowie zu ihren Einstellungen, Erfahrungen und Kenntnissen zu Angstpatienten befragt und mit einer Kontrollgruppe verglichen. Es zeigte sich, daβ Angstpatienten in der Allgemeinarztpraxis viel Zeitaufwand beanspruchen und sowohl die diagnostischen als auch die therapeutischen Kenntnisse nicht zufriedenstellend sind. Das Fortbildungsprogramm wurde von den Teilnehmern sehr gut beurteilt. Durch die Teilnahme wurde in Teilgruppen eine Verbesserung vor allem der Kenntnisse im Bereich «Angststörungen erkennen/Diagnostik» erreicht. Das Patientenseminar wurde vom Groβteil der Teilnehmer sowohl in Gruppen als auch bei einzelnen Patienten in der Praxis durchgeführt. Es wird deutlich, daβ trotz des hohen Aufwandes eine groβe Akzeptanz für den Einsatz solcher Patienten-seminare vorhanden ist und daβ insgesamt die bisher untersuchten Variablen für eine überraschend hohe Effektivität der Fortbildungsmaβnahmen sprechen. / This artide describes preliminary results of an evaluation study of the patientseminar 'anxiety', an educational programme for physicians. Before and after the two seminar meetings, 109 participants of part land 104 participants of part II filled in a questionnaire about their opinion on the programme as weil as their attitudes, experience, and knowledge about anxiety patients. They were compared with a control group, which did not take part in the programme. It is found that anxiety patients call for a lot of attention at general practitioners' and that the physicians' diagnostic and therapeutic knowledge is not sufficient. The educational programme was highly rated by participants. The patientseminar was conducted, for the greater part of participants, by the physicians both in groups and for single patients. It became evident that in spite of high expenses there is a wide acceptance of such patientseminars and that the variables so far examined up to now indicate surprisingly high efficiency of the educational programme.

Childhood Separation Anxiety and the Risk of Subsequent Psychopathology: Results from a Community Study

Brückl, Tanja M., Wittchen, Hans-Ulrich, Höfler, Michael, Pfister, Hildegard, Schneider, Silvia, Lieb, Roselind 29 November 2012 (has links) (PDF)
Objective: To examine the association between separation anxiety disorder (SAD) and mental disorders in a community sample and to evaluate whether separation anxiety is specifically related to panic disorder with and without agoraphobia. Method: The data come from a 4-year, prospective longitudinal study of a representative cohort of adolescents and young adults aged 14–24 years at baseline in Munich, Germany. The present analyses are based on a subsample of the younger cohort that completed baseline and two follow-up investigations (n = 1,090). DSM-IV diagnoses were made using the Munich Composite International Diagnostic Interview. Cox regressions with time-dependent covariates were used to examine whether prior SAD is associated with an increased risk for subsequent mental disorders. Results: Participants meeting DSM-IV criteria for SAD were at an increased risk of developing subsequent panic disorder with agoraphobia (PDAG) (HR = 18.1, 95% CI = 5.6–58.7), specific phobia (HR = 2.7, 95% CI = 1.001–7.6), generalized anxiety disorder (HR = 9.4, 95% CI = 1.8–48.7), obsessive-compulsive disorder (HR = 10.7, 95% CI = 1.7–66.1), bipolar disorder (HR = 7.7, 95% CI = 2.8–20.8), pain disorder (HR = 3.5, 95% CI = 1.3–9.1), and alcohol dependence (HR = 4.7, 95% CI = 1.7–12.4). Increased hazard rates for PDAG (HR = 4.2, 95% CI = 1.4–12.1), bipolar disorder type II (HR = 8.1, 95% CI = 2.3–27.4), pain disorder (HR = 1.9, 95% CI = 1.01–3.5), and alcohol dependence (HR = 2.1, 95% CI = 1.1–4.) were also found for subjects fulfilling subthreshold SAD. Conclusions: Although revealing a strong association between SAD and PDAG, our results argue against a specific SAD-PDAG relationship. PDAG was neither a specific outcome nor a complete mediator variable of SAD.

Mechanism of action in CBT (MAC): methods of a multi-center randomized controlled trial in 369 patients with panic disorder and agoraphobia

Gloster, Andrew T., Wittchen, Hans-Ulrich, Einsle, Franziska, Höfler, Michael, Lang, Thomas, Helbig-Lang, Sylvia, Fydrich, Thomas, Fehm, Lydia, Hamm, Alfons O., Richter, Jan, Alpers, Georg W., Gerlach, Alexander L., Ströhle, Andreas, Kircher, Tilo, Deckert, Jürgen, Zwanzger, Peter, Arolt, Volker 22 February 2013 (has links) (PDF)
Cognitive behavioral therapy (CBT) is efficacious for panic disorder with agoraphobia (PD/A). Nevertheless, the active ingredients of treatment and the mechanisms through which CBT achieves its effects remain largely unknown. The mechanisms of action in CBT (MAC) study was established to investigate these questions in 369 patients diagnosed with PD/A. The MAC study utilized a multi-center, randomized controlled design, with two active treatment conditions in which the administration of exposure was varied, and a wait-list control group. The special feature of MAC is the way in which imbedded experimental, psychophysiological, and neurobiological paradigms were included to elucidate therapeutic and psychopathological processes. This paper describes the aims and goals of the MAC study and the methods utilized to achieve them. All aspects of the research design (e.g., assessments, treatment, experimental procedures) were implemented so as to facilitate the detection of active therapeutic components, and the mediators and moderators of therapeutic change. To this end, clinical, behavioral, physiological, experimental, and genetic data were collected and will be integrated.

The many faces of social anxiety disorder

Wittchen, Hans-Ulrich 01 February 2013 (has links) (PDF)
Social anxiety disorder, also known as social phobia, is one of the most prevalent anxiety disorders, affecting 7-13% of subjects in the community at some time in their lives. Despite being eminently treatable, it remains largely under-recognised and, therefore, undertreated. The disorder is characterized by a fear of scrutiny by others, with sufferers experiencing excessive anxiety in social and performance situations. This excessive anxiety usually leads to avoidance behaviour that can severely affect normal daily living. With onset commonly occurring during childhood or adolescence, social anxiety disorder may disrupt normal patterns of development of social and personal relationships, often having a long-term impact on emotional stability in social or working life. If left untreated, the course of social anxiety disorder is frequently complicated with comorbid conditions, particularly major depression or substance abuse. This review assesses the size of the clinical problem by evaluating current and lifetime prevalence estimates, age of onset, risk factors and evolution of the clinical course; thereby providing the rationale for early recognition and prompt treatment.

Duloxetine treatment for relapse prevention in adults with generalized anxiety disorder: A double-blind placebo-controlled trial

Davidson, Jonathan R.T., Wittchen, Hans-Ulrich, Llorca, Pierre-Michel, Erickson, Janelle, Detke, Michael, Ball, Susan G., Russell, James M. 10 April 2013 (has links) (PDF)
The objective was to examine duloxetine 60–120mg/day treatment for relapse prevention in adults with generalized anxiety disorder (GAD). Adult patients (N=887; mean age=43.3 years; 61.0% female) with DSM-IV-TR-defined GAD diagnosis were treated with duloxetine for 26 weeks. Patients who completed open-label phase and were treatment responders (≥50% reduction in Hamilton Anxiety Rating Scale total score to ≤11 and “much”/“very much improved” ratings for the last 2 visits of open-label phase) were randomly assigned to receive duloxetine or placebo for a 26-week double-blind continuation phase. Relapse was defined as ≥2-point increase in illness severity ratings or by discontinuation due to lack of efficacy. During the double-blind phase, placebo-treated patients (N=201) relapsed more frequently (41.8%) than duloxetine-treated patients (13.7%, N=204, P≤0.001) and worsened on each outcome measure (P≤0.001, all comparisons). Duloxetine 60–120 mg/day treatment was efficacious and reduced risk of relapse in patients with GAD.

Generalisierte Angststörungen in der primärärztlichen Versorgung / Generalised anxiety disorder in primary care

Hoyer, Jürgen, Wittchen, Hans-Ulrich 03 December 2012 (has links) (PDF)
Der Beitrag untersucht auf der Grundlage neuer primärärztlicher Befunde die Versorgungsqualität bei der hinsichtlich Chronizität und Arbeitsausfall schwerwiegendsten Angsterkrankung, der Generalisierten Angststörung. Neben einer knappen Einführung in das Störungsbild werden die an über 20 000 Patienten in 558 Hausarztpraxen gewonnenen Kernbefunde der GAD-P-Studie (Generalisierte Angst und Depression in der Primärärztlichen Versorgung) zusammengefasst und Ansatzpunkte zur Verbesserung der Versorgungsqualität dieses selten adäquat behandelten Störungsbildes diskutiert. Insbesondere wird auf die zentrale Bedeutung einer sichereren diagnostischen Erkennung als Voraussetzung für therapeutische Verbesserungen hingewiesen. In Ergänzung zur Verbesserung bestehender Weiterbildungsangebote wird auf Arzt- und Patientenebene der breitere Einsatz bestehender Screeningverfahren, die Nutzung krankheitsspezifischer Patientenratgeber, sowie eine breitere Öffentlichkeitsarbeit zur Information über dieses bislang vernachlässigte, häufig chronisch verlaufende Krankheitsbild empfohlen. / Based on new empirical findings in a large-scale primary care study, the quality of care for the most chronic and debilitating anxiety problem, generalised anxiety disorder, is examined. Following a brief introduction of this disorder, the core findings of the GAD-P study (generalised anxiety and depression in primary care) with more than 20,000 patients of 558 family doctor practices are summarised and measures to improve the quality of care of patients with generalised anxiety disorder, a disorder which is rarely adequately treated, are discussed. This paper particularly emphasises the standard use of time-efficient diagnostic screening instruments, because improved recognition and diagnosis is the prerequisite for appropriate treatment. Further the role of the media to increase awareness of this disorder as well as patient education materials to improve compliance and to enhance treatment outcome effects are highlighted.

Associations of familial risk factors with social fears and social phobia: evidence for the continuum hypothesis in social anxiety disorder?

Knappe, Susanne, Beesdo, Katja, Fehm, Lydia, Lieb, Roselind, Wittchen, Hans-Ulrich 20 February 2013 (has links) (PDF)
We examined parental psychopathology and family environment in subthreshold and DSM-IV threshold conditions of social anxiety disorder (SAD) in a representative cohort sample of 1,395 adolescents. Offspring and parental psychopathology was assessed using the DIAX/ M-CIDI; recalled parental rearing and family functioning via questionnaire. Diagnostic interviews in parents were supplemented by family history reports from offspring. The cumulative lifetime incidence was 23.07% for symptomatic SAD, and 18.38 and 7.41% for subthreshold and threshold SAD, respectively. The specific parent-tooffspring association for SAD occurred for threshold SAD only. For subthreshold and threshold SAD similar associations were found with other parental anxiety disorders, depression and substance use disorders. Parental rearing behaviour, but not family functioning, was associated with offspring threshold SAD, and although less strong and less consistent, also with subthreshold SAD. Results suggest a continued graded relationship between familial risk factors and offspring SAD. Parental psychopathology and negative parental styles may be used defining high-risk groups to assign individuals with already subthreshold conditions of SAD to early intervention programs.
