Aus der Einleitung: "In den vergangenen 15 Jahren sind in verschiedenen Ländern der Welt größere epidemiologische Studien zur Häufigkeit psychischer Störungen in der Allgemeinbevölkerung durchgeführt worden, die auch eine grobe Abschätzung der Häufigkeit Sozialer Phobien erlauben. Ein Überblick über diese Studien ergibt allerdings auf den ersten Blick ein recht verwirrendes Bild, da die Prävalenzabschätzungen der verschiedenen Studien eine scheinbar widersprüchliche Befundlage erkennen lassen. Ältere - vor Einführung expliziter diagnostischer Kriterien für Soziale Phobi durchgeführte Studien aus den 60er und frühen 70er Jahren - schätzten die Prävalenz dieses Krankheitsbildes auf lediglich 1% (1).

Background. The proposed revisions of the ICD and DSM diagnostic systems have led to increased interest in evaluation of diagnostic criteria. This report focuses on the DSM-IV requirement that episodes of generalized anxiety disorder (GAD) must persist for at least 6 months. Community epidemiological data are used to study the implications of changing this requirement in the range 1–12 months for estimates of prevalence, onset, course, impairment, co-morbidity, associations with parental GAD, and sociodemographic correlates. Method. Data come from the US National Comorbidity Survey Replication (NCS-R), a US household survey carried out during 2001–2003. Version 3.0 of the WHO Composite International Diagnostic Interview (WMH-CIDI) was used to assess DSM-IV anxiety disorders, mood disorders, substance disorders, and impulse-control disorders. Results. Lifetime, 12-month, and 30-day prevalence estimates of DSM-IV GAD changed from 6·1%, 2·9%, and 1·8% to 4·2–12·7%, 2·2–5·5%, and 1·6–2·6% when the duration requirement was changed from 6 months to 1–12 months. Cases with episodes of 1–5 months did not differ greatly from those with episodes of [gt-or-equal, slanted]6 months in onset, persistence, impairment, co-morbidity, parental GAD, or sociodemographic correlates. Conclusions. A large number of people suffer from a GAD-like syndrome with episodes of <6 months duration. Little basis for excluding these people from a diagnosis is found in the associations examined here.

Theoretischer Hintergrund: Die diagnostischen Kriterien der Generalisierten Angststörung (GAS) und ihr Status als eigenständige psychische Störung waren lange umstritten. Inzwischen liegen neuere epidemiologische Daten vor, die ein präziseres Bild dieser Störung und ihrer Besonderheiten ermöglichen. Methode: Es wird ein systematischer Überblick zu Prävalenz, Verlauf und Komorbidität, zur Beeinträchtigung und zum Inanspruchnahmeverhalten sowie zur Spezifität des Kernsymptoms (Sorgen) erstellt. Ergebnisse: GAS ist eine häufige Störung, die im jungen Erwachsenenalter einsetzt, jedoch auch – anders als andere Angststörungen – hohe Inzidenzraten im mittleren Lebensalter aufweist. Der Verlauf ist eher chronisch. Trotz hoher Komorbidität lässt sich die Störung valide abgrenzen. Klinisch relevante Sorgen erweisen sich als störungsspezifisch. Die Beeinträchtigungen sind auch bei GAS-Patienten ohne Komorbidität beträchtlich. Schlussfolgerung: Der Forschungsstand spricht für die Bedeutung und Eigenständigkeit der Diagnose sowie für die stärkere Beachtung offener Forschungsfragen. / Background: The diagnostic criteria for generalized anxiety disorder (GAD) and its status as an independent mental disorder have been controversial. More recent epidemiological data provide a more precise picture of this disorder and its specific features. Methods: A systematic overview is given in regard to prevalence, course and comorbidity, impairment, and help-seeking behavior as well as to specificity of the core symptom (worries). Results: GAD is a frequent disorder with high incidence rates in middle-age groups, which are not seen in other anxiety disorders. Despite the high comorbidity GAD can be validly distinguished. Clinically relevant worries have been proven as specific for the disorder. The impairments are also considerable for patients without comorbid disorders. Conclusions: Research supports the independent status of GAD and the importance of this diagnosis. Unsolved questions are to be analyzed in future research.

Social anxiety disorder (SAD) is the 3rd most common psychiatric diagnosis, and is associated with significant social, occupational, health, and educational impairment. Fortunately, both pharmacological and psychological treatments can reduce symptoms. Cognitive behavioral therapy is considered the gold standard treatment for SAD, and a robust literature supports its effectiveness. In contrast, process related factors, including the role of the working alliance, have received less attention in treatment of SAD. The current study examined development of the working alliance for a SAD sample. The working alliance is characterized as the collaborative relationship between a client and therapist, and includes shared goals, strategies, and an attachment bond. Within the context of SAD, the working alliance is particularly interesting, as the alliance itself is a social relationship that may elicit anxiety, which, in turn, may impact development of the alliance. The present study also investigated whether treatment type, that is, exposure group therapy (EGT) versus virtual reality exposure (VRE) therapy, or pre-treatment symptom severity influenced the working alliance trajectory. Data were provided by an adult sample presenting with a primary diagnosis of SAD. Participants were randomly assigned to one of two treatment conditions, both involved use of a manualized CBT treatment approach. Standardized measures of social anxiety were administered pre-treatment whereas working alliance ratings were obtained after each session. Results indicated high levels of working alliance and significant change in ratings over time. Treatment condition did not contribute to significant differences in the working alliance trajectory. Regarding the impact of SAD symptoms, initially high ratings of fear was associated with progressively increasing rates of growth in the working alliance whereas high initial ratings of avoidance signified steeper increase in the working alliance earlier in treatment followed by a declining rate of change over time. The current study contributes to the limited literature regarding the working alliance trajectory for clients with SAD, and is the first to consider the impact of VRE treatment on this trajectory. Findings also provide preliminary evidence for the differential impact of initial fear and avoidance as well as a potential curvature for the working alliance trajectory when using CBT.

Objective: To examine in a nationally representative sample (a) the differential association of specific anxiety and depressive disorders defined according to DSM-IV with pain disorder (PD) and pain symptoms, and (b) whether pain-associated anxiety and depressive disorders and their comorbidity have different implications in terms of impairment, disability, health care utilization, and substance use. Method: A nationally representative community study was conducted in Germany. Symptoms, syndromes and diagnoses of mental disorders, and pain were assessed in N = 4,181 participants aged 18–65 years using the DSM-IV/M-CIDI. Results: Logistic regressions revealed that pain is associated with both specific anxiety and depressive disorders, with increasing significant odds ratios (OR) for medically explained pain symptoms (EPS; OR range: 1.9–2.0), to unexplained pain symptoms (UPS; OR range: 2.4–7.3), to PD (OR range: 3.3–14.8). PD and UPS persistently showed associations after adjusting for comorbid other anxiety and depressive disorders and physical illnesses. All types of pain, particularly PD/UPS, are associated with decreased quality of life, greater impairment in role functioning, disability, health care utilization, and substance use. Depressive disorders, even more so anxiety disorders and their comorbidity account for a substantial proportion of variance in these functional correlates. Conclusions: Pain is strongly associated with specific anxiety and depressive disorders. In light of the individual and societal burden due to pain, and the demonstrated role of comorbid anxiety or/and depression, our results call for further investigation of the underlying mechanisms for this association as well as targeted treatments for these comorbidities.

Separation anxiety disorder (SAD) is rarely considered in adults presenting with anxious symptomatology, but a growing body of evidence suggests that its symptoms are experienced by a significant number of adults. Early parent-child relationships are an especially important area of study for understanding SAD. Moreover, the attachment style that is formed through early parent-child interactions may serve as a mediator to later expression of symptoms of adult separation anxiety (ASA). Studying the early parent-child relationship and perceived parenting styles in conjunction with individual attachment styles will allow for a more systemic approach to understanding potential risk factors for the development of ASA. Young adult college students may be particularly vulnerable to ASA as they transition into college and away from primary caregivers. This study investigates a mediational model with individual attachment style serving as a mediator between perceived early parenting styles and symptoms of ASA in 170 first-year college students between the ages of 18-20. As anticipated a large percent of the sample endorsed clinically significant levels of symptoms of ASA (47%). In addition, results utilizing bootstrapping analyses demonstrated that a perceived indifferent parenting style had an indirect effect on symptoms of ASA, with the effect occurring through an anxious attachment style. Support for the mediation model was obtained when statistically controlling for perceived parenting styles of overcontrol and abuse as well as confounding variables including age, sex, number of different families lived with and emotionality domains of temperament (distress, anger, and fearfulness). Highlighting the role of perceived parenting styles and attachment styles in the development of symptoms of ASA will serve to establish potential family-based interventions and help in the development of prevention programs. Examining symptoms of ASA in young adult college students may result in the development of university-based psycho-educational programs to help these students master a challenging transitional period. This study is one of the first to explore a model that can help to explain the developmental trajectory of symptoms of ASA. Future studies are encouraged to consider symptoms of ASA when investigating anxious symptomatology in adult populations.

Homework compliance has been identified as a robust predictor of treatment outcome for depression and, to a lesser extent, anxiety disorders, including social phobia. The current study tested the following hypotheses: (1) homework compliance is positively related to ratings of global improvement, (2) homework compliance is negatively related to symptom reduction, (3) the relation between homework compliance and treatment outcome varies according to the nature of the homework exercise, and (4) expectancy is positively related to early homework compliance, in a clinical sample of individuals with social phobia. Results provided limited support for the relation between compliance and ratings of improvement, but did not support a negative relation between compliance and symptom reduction. Further, the results provided limited support for the hypothesis that compliance with exposure versus non-exposure homework would differ significantly in terms of their relation to treatment outcome, but did not support the relation between compliance and expectancy.

Though the field of psychology is moving forward in its awareness of the importance of studying and addressing cultural issues, there is still a dearth of literature on the subject, especially in the area of anxiety (Heurtin-Roberts, Snowden, & Miller, 1997). The current study tested the following hypotheses 1) African-Americans’ self-reported concerns over confirming stereotypes would be related to their own self-reported levels of social anxiety. 2) There would be a negative relationship between how negatively African-Americans think others view African-Americans in general, and levels of social anxiety; 3) The relationship between public regard, concern over confirming stereotypes, and levels of anxiety would be partially mediated by beliefs about the probability and consequences of a negative outcome from their speech for group members. Results showed that the relation between public regard and fear of negative evaluations was fully mediated by the consequences of a negative outcome for group members.

Background: It is commonly assumed that there are clear lines of demarcation between anxiety and depressive disorders on the one hand and psychosis on the other. Recent evidence, however, suggests that this principle may be in need of updating. Methods: Depressive and/or anxiety disorders, with no previous history of psychotic disorder, were examined for the presence of psychotic symptoms in a representative community sample of adolescents and young adults (Early Developmental Stages of Psychopathology study; n=3021). Associations and consequences of psychotic symptomatology in the course of these disorders were examined in terms of demographic distribution, illness severity, onset of service use, and risk factors. Results: Around 27% of those with disorders of anxiety and depression displayed one or more psychotic symptoms, vs 14% in those without these disorders (OR 2.23, 95% CI 1.89–2.66, P < .001). Presence as compared with nonpresence of psychotic symptomatology was associated with younger age (P < .0001), male sex (P < .0058), and poorer illness course (P < .0002). In addition, there was greater persistence of schizotypal (P < .0001) and negative symptoms (P < .0170), more observable illness behavior (P < .0001), greater likelihood of service use (P < .0069), as well as more evidence of familial liability for mental illness (P < .0100), exposure to trauma (P < .0150), recent and more distant life events (P < .0006–.0244), cannabis use (P < .0009), and any drug use (P < .0008). Conclusion: Copresence of psychotic symptomatology in disorders of anxiety and depression is common and a functionally and etiologically highly relevant feature, reinforcing the view that psychopathology is represented by a network or overlapping and reciprocally impacting dimensional liabilities.

Social Anxiety Disorder (SAD) is a mental disorder with high prevalence but low treatment accessibility. A way to facilitate care to these patients is through Internet based treatment. As is the case of most psychological treatments, much has been studied about positive effects but there is a gap regarding adverse effects. This study seeks to fill this gap in the case of an Internet delivered treatment. From a total of 127 participants who took part in a treatment that combined attention biased modification (ABM) and Internet based cognitive behavior therapy (iCBT), 21 (16.5%) presented adverse effects. Most of the adverse effects were detected after participants had received iCBT (13.4%), and these were mostly related to deterioration of symptoms (5.5%), negative wellbeing (3.9%) and emergence of new symptoms (1.6%). Perceived side effects after attention training were less common (4.7%). A thematic analysis showed also that the techniques used in treatment, the lack of time to complete treatment and becoming aware with the impairments of the disorder and its consequences could influence the emergence of adverse effects.
