Erythrophobie wird als klinische Bezeichnung für die Angst zu erröten verwendet, wenn das Einzelsymptom Erröten im Vordergrund einer Angstproblematik steht. Die vorliegende Übersicht beruht auf einer umfangreichen Literaturrecherche und wird ergänzt durch eigene klinische Beobachtungen aus einer Pilotstudie zur kognitiv-behavioralen Gruppentherapie der Errötungsangst. Wir referieren den aktuellen Kenntnisstand zu Erythrophobie in Bezug auf die differentialdiagnostische Einordnung, auf ätiologische und pathogenetische Konzepte sowie auf die Verhaltenstherapie der Störung. Insgesamt zeigt die Übersicht, dass Erythrophobie am sinnvollsten als Subsyndrom der Sozialen Phobie beschrieben werden kann. Patienten mit Errötungsangst als Hauptbeschwerde unterscheiden sich jedoch von anderen Patienten mit Sozialer Phobie im Hinblick auf Behandlungsanliegen, Inanspruchnahmeverhalten, Behandlungserwartung und Therapieziele sowie durch spezifische aufrechterhaltende Mechanismen der Störung, insbesondere durch eine übertriebene und inflexible Aufmerksamkeitsfokussierung auf körperliche Symptome. Der Einsatz eines Aufmerksamkeitstrainings als spezifisches Behandlungsmodul bei Errötungsangst ist vielversprechend und sollte in bekannte Ansätze zur Therapie der Sozialen Phobie integriert werden. Abschließend werden Impulse für weiterführende Forschungsaktivitäten skizziert. / Erythrophobia is the pathological form of fear of blushing. This review is based upon an extensive literature research and supplemented by clinical observations from a pilot study of a cognitive-behavioural group therapy for fear of blushing. Current knowledge about fear of blushing is reported regarding diagnostic considerations, aetiologic and pathogenetic mechanisms, and cognitive-behavioural therapy. In conclusion, this review indicates that fear of blushing should be classified as a sub-syndrome of social phobia. Patients suffering from fear of blushing as predominant complaint differ from other patients with social phobia in health-care utilisation, treatment expectation and treatment goals. However, the most prominent difference lies in the exaggerated and inflexible self-focused attention these patients direct to their arousal and bodily symptoms. Therefore, attention training as a specific treatment unit is promising and should be integrated in standard treatment approaches for social phobia. Finally, options for further research are outlined. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw. Nationallizenz frei zugänglich.

Bakgrund: För att halitosis ska tas på större allvar och för att de drabbade individerna ska få rätt sorts stöd är det av stor vikt att identifiera samt uppmärksamma halitosis eventuella effekter på livskvaliteten. Syftet: Syftet med studien var att identifiera och sammanställa kunskap kring halitosis eventuella effekter på upplevd livskvalitet med speciellt avseende på oralhälsorelaterad livskvalitet, social ångest och sociala relationer. Metod:Examensarbetet är en allmän litteraturstudie där systematiska och manuella sökningar användes för att finna artiklar. Resultat: Studiens resultat är baserat på 17 vetenskapliga originalartiklar. Gemensamt visar artiklarna en negativ korrelation mellan halitosis och oralhälsorelaterad livskvalitet, halitosis och social ångest eller halitosis och sociala relationer. Majoriteten av artiklarna visar att individer med halitosis anpassar sina sociala liv efter symptomet. Slutsats: Halitosis kan konstateras vara mer än bara dålig andedräkt. Genom att bland annat ha en negativ påverkan på en individs självförtroende kan halitosis leda till psykisk ohälsa i form av social ångest, försvårade sociala relationer och försämrad oral hälsorelaterad livskvalitet vilket kan påverka livskvaliteten. Det är därför av stor vikt att tandvårdspersonal beaktar den orala hälsan ur ett bredare perspektiv där halitosis kan uppmärksammas. / Background: In order for halitosis to be taken more seriously and for the affected individuals to receive the right kind of support, it is important to identify and pay attention to halitosis's possible effects on the quality of life. Aim:The aim of the study was to identify and compile knowledge about halitosis possible impact on perceived quality of life particulary regarding oral health related quality of life, social anxiety and social relationships. Method: The study was a general literature study where systematic and manual searches, in three different databases, were used to find articles. The selection of articles where made in three steps. Results: The study results is based on 17 scientific original articles. The articles mutually show a negative correlation between halitosis and oral health-related quality of life, halitosis and social anxiety or halitosis and social relationships. Conclusion:By affecting an individual's self- esteem, halitosis can lead to psychological distress in terms of social anxiety, impaired social relationships and impaired oral health related quality of life, which can affect the general quality of life. It is therefore at the utmost importance that dental professionals take oral health into account from a broader perspective where halitosis can be noted.

Parmi tous les problèmes de santé chronique, les troubles anxieux combinent une prévalenceélevée, une apparition précoce, une chronicité élevée et des conséquences sur lefonctionnement majeur. Or l’anxiété comme pathologie a été plutôt évaluée d’un point de vueclinique ; l’impact des sous types sur la qualité de vie et les coûts a été de façon généralemoins étudié, surtout sur l’impact à long terme, et les études présentent des variationsimportantes d’estimation des coûts.Il est intéressant d’évaluer ces sous types de trouble anxieux du point de vu de la qualité devie liée a la santé ainsi que les paramètres objectifs des consommations de soins et coûts ;l’étude des conséquences de la rechute est particulièrement importante. Nous avons mesuréles coûts associés à l’ensemble des sous types des troubles anxieux, en utilisant une extractiond’une base de données administrative américaine sur plusieurs centaines de milliers depatients, et ainsi permis d’avoir un estimé précis des coûts médicaux, de comparer les coûtsassociés aux différents diagnostics d’anxiété, de les comparer à ceux de l’épisode dépressif, etde l’influence de la relation dynamique entre les troubles anxieux et la dépression. Nousavons ensuite étudié l’évolution de l’impact sur la qualité de vie et le fonctionnement duTrouble Anxieux Généralisé et de la Phobie Sociale à travers deux essais cliniques et estimédans ces essais les utilités associées à des états de santé. Des efforts de recherche accrus sontnécessaires pour fournir des données prospectives sur l’aspect dynamique des TroublesAnxieux et de la dépression, et évaluer les coûts indirects également en pratique cliniquecourante. / Anxiety disorders are unique among all chronic conditions, both physical and mental, inhaving a combination of very high prevalence, early age at onset, high chronicity, andsubstantial role impairment. Anxiety disorder was mostly evaluated of a clinical standpoint;the impact of subtypes on the quality of life and costs were generally less studied, especiallyon long-term impact, and studies show large variations of cost estimates. It is interesting toevaluate these subtypes of anxiety disorder from the point of view of health related quality oflife and the objective parameters of health care consumption and costs. The consequences ofrelapse are of particular importance due to the chronicity of these disorders. We measured thecosts associated with all subtypes of anxiety disorders, using an extraction of a U.S.administrative database on hundreds of thousands of patients, and thus allowed to have anaccurate estimate of medical costs, compared the costs associated with different diagnoses ofanxiety, compared with those of the depressive episode, and studied the dynamic relationshipbetween anxiety disorders and depression. We then studied the evolution of the impact onquality of life and functioning of the Generalised Anxiety Disorder and Social Phobia throughtwo randomised clinical trials and found in these tests associated utilities to health states.Increased research efforts are needed to provide prospective data on the dynamic aspect ofAnxiety Disorders and Depression, and to also measure the indirect costs in clinical practice.

Diferentes ensaios clínicos randomizados demonstram que a Terapia Cognitivo-Comportamental (TCC) é muito efetiva no tratamento do Transtorno de Ansiedade Social (TAS). Entretanto, uma quantidade significativa de pacientes não apresentam melhora após a finalização da intervenção com TCC. Tal dado indica a necessidade de desenvolver novas estratégias de tratamento para o TAS. A Terapia Cognitiva Processual (TCP) é uma nova abordagem dentro do campo da TCC que tem como principal objetivo auxiliar os pacientes a identificar e modificar suas crenças centrais disfuncionais, sendo o Processo uma das principais técnicas utilizadas. Algumas pesquisas têm demonstrado a efetividade do Processo no tratamento do TAS e de outros transtornos psiquiátricos. Entretanto, novas pesquisas são necessárias para avaliação não somente de tal técnica, mas de todo o protocolo de intervenção da TCP. Esta pesquisa objetivou avaliar se participantes que receberam uma intervenção individual em TCP apresentam diferenças em relação a sintomas de ansiedade social, medo da avaliação negativa, esquiva e desconforto social, ansiedade, depressão, sofrimento psíquico, distorções cognitivas e viés atencional. Este é um ensaio clínico randomizado que comparou um grupo que recebeu intervenção em TCP e um grupo lista de espera no tratamento do TAS. O estudo apresenta três grupos de pesquisa: o TCP (n =18), o lista de espera (n =21) e o saudável (n =19). Um pesquisador independente ao estudo realizou a distribuição aleatória dos participantes com TAS entre os grupos TCP e lista de espera. Foram realizadas avaliações no pré e pós-teste através de diferentes escalas de auto-relato e do teste de Stroop emocional. Adicionalmente, o grupo TCP respondeu tais escalas a cada quatro sessões. O tratamento foi realizado em 16 sessões com duração de 1h30min cada utilizando a TCP no formato individual. Houve uma redução significativa nos sintomas de ansiedade social, ansiedade, depressão, esquiva e desconforto social, e sofrimento psíquico no grupo TCP ao longo do tratamento (p < 0,05). Tais reduções foram associadas a tamanhos de efeito grandes. Não foram observadas mudanças em nenhum dos instrumentos utilizados no grupo lista de espera (p > 0,05). Houve ainda uma significativa redução no medo da avaliação negativa após a utilização do Processo no grupo tratado, além de uma redução em distorções cognitivas (p < 0,05). Não foram observadas diferenças no pré e pós-teste em relação ao viés atencional nos três grupos da pesquisa (p > 0,05). Este estudo sugere que a TCP pode ser uma nova abordagem clínica efetiva no tratamento do TAS associado à diferentes comorbidades, haja vista que houve uma redução em sintomas de ansiedade social e sintomas comórbidos / Different randomized clinical trials show that Cognitive Behavioral Therapy (CBT) is highly effective in the treatment of Social Anxiety Disorder (SAD). However, a large number of patients do not show improvement after receiving CBT. This indicates that it is important to develop new treatments for SAD. Trial-Based Cognitive Therapy (TBCT) is a new approach within the field of CBT area. It aims to help patients to identify and to modify their dysfunctional core beliefs. One of the main TBCT techniques proposed by TBCT is the Trial. Some research studies have demonstrated the effectiveness of Trial in the treatment of SAD, and other disorders. However, further investigation is needed to firmly establish the efficacy not just for the Trial technique, but also the TBCT approach as a treatment for SAD and other disorders. This research aims to evaluate wheter SAD participants receiving TBCT individual-sessions differ from a SAD waiting list group condition regarding symptoms of social anxiety, fear of negative evaluation, social avoidance and distress, anxiety, depression, mental suffering, and attentional bias. This is a randomized clinical trial comparing TBCT and a Waitlist control condition for the treatment of SAD. The study has three groups: TBCT (n =18), Wailist (n =21), and healthy group (n =19). An independent researcher to study distributed randomly the participants with SAD between TBCT or Waitlist condition. Assessments were made at pre and post-test using several self-report scales, and the emotional Stroop test in the three groups. Additionaly, the TBCT group answered these scales each four sessions. The treatment was delivered in sixteen 1.5 hour sessions using the individual TBCT format. There were reductions in social anxiety, anxiety, depression, social avoidance and distress, and mental suffering symptoms at TBCT group (p < 0.05), but not in the Waitlist group (p > 0.05). Those reductions were associated with a large effect size. There was a significant reduction at fear of negative evaluation after Trial use, and reductions at cognitive distortions throughout the treatment as well (p < 0.05). There were no differences among the three groups regarding attentional bias at pre-test nor at post-test (p > 0.05). This study suggests that TBCT may be a new effective clinical approach to treat SAD associated with high rates of comorbidity, as there were significant reductions in the comorbid symptoms

Meta-cognitive models have been utilized to explore the relations between worry and generalized anxiety disorder, as well as, the associations between rumination and depression. However, relatively few studies have focused on the role of meta-cognitive variables and social phobia symptoms. It is possible that individuals with social phobia follow a pattern of thinking similar to that of those who experience depressive rumination and worry. Specifically, it may be that individuals with social phobia hold positive beliefs about their highly negative prolonged post-event evaluations of social interactions. The primary goal of this study was the development and assessment of the Positive Beliefs about Post-Event Processing Questionnaire (PB-PEPQ). Further, it was predicted that post-event processing would mediate the relationship between positive beliefs about post-event processing and social phobia symptoms. The findings from this study suggested that the PB-PEPQ is a valid and reliable construct. Additionally, the findings provide initial evidence for a cognitive model in which individuals who tend to hold positive beliefs about post-event processing, tend to engage in post-event processing which may increase social phobia symptoms.

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.

Parental psychopathology and unfavorable family environment are established risk factors for onset of offspring social phobia (SP), but their associations with the further course, e.g., persistence of the disorder, remain understudied. A community cohort of 1395 adolescents and their parents was followed-up over almost 10 years using the DIA-X/M-CIDI. Parental diagnostic interviews were supplemented by family history data. Parental rearing was retrospectively assessed by the Questionnaire of Recalled Parental Rearing Behavior in offspring, and family functioning by the Family Assessment Device in parents. Persistence measures (proportion of years affected since onset) were derived from diagnostic interviews, using age of onset, age of recency, and course information. Lack of emotional warmth and dysfunctional family functioning characteristics were associated with higher SP persistence, particularly in interaction with parental psychopathology. Predictors for SP persistence differ from those predicting SP onset. Unfavorable family environment alone and in interaction with parental disorders predict higher SP persistence.

Die vorliegende Studie untersuchte emotionale Reaktionen im Experimentaldesign einer aversiven, differentiellen klassischen Konditionierung (CS = zwei männliche, neutral valente Gesichter; olfaktorischer UCS = vergorene Hefe) bei je vierzehn männlichen generalisierten Sozialphobikern (DSM-VI) und gesunden Kontrollpersonen. In Erwartung einer erhöhten Konditionierbarkeit, einer Extinktionsresistenz sowie einer Generalisierung auf störungsrelevante Fazialreize bei den Sozialphobikern wurden die konditionierten Reaktionen über subjektiv-verbale Urteile (Valenz, Erregung, Kontingenz), den Schreckreflex (M. orbicularis oculi links, Indikator subcorticaler Reizverarbeitung der Angst), die bilateral erhobene Aktivität des M. corrugator supercilii (Indikator für den negativ emotionalen Fazialausdruck) sowie die Herzrate (Indikator der allgemeinen psychophysiologischen Aktivierung) gemessen. Die Konditionierung verlief in beiden Experimentalgruppen erfolgreich (Valenz, Erregung, Kontingenz) und hypothesenkonform. Im Gegensatz zu den Gesunden resultierten für die Sozialphobiker eine erhöhte Konditionierbarkeit (Schreckreflexlatenz und -amplitude, Herzratendezeleration), eine Extinktionsresistenz (Erregung, Schreckreflexnullreaktionen, Corrugator) sowie eine Reizgeneralisierung (Erregung, Kontingenz, Schreckreflexlatenz, Corrugator, Herzratendezeleration). Die Befunde sprechen außerdem für eine unterschiedliche emotionale Reizverarbeitung über den Experimentalverlauf. Die Sozialphobiker reagierten in der Akquisition vorrangig in den Parametern Erregung, Kontingenz, Schreckreflex und Herzrate (Gesunde: Corrugator) sowie in der Extinktion hinsichtlich Erregung, Schreckreflex und Corrugator (Gesunde: Kontingenz). Das Valenzurteil ergab hingegen keine Gruppenspezifik. / The present study investigated the emotional responses of aversive differential Pavlovian conditioning with two male neutral faces as conditioned stimuli (CS) and a foul odor (fermented yeast) as unconditioned stimulus (UCS) in fourteen male generalized social phobics (DSM-VI) and healthy controls. The aim of this investigation was to examine the hypotheses of enhanced acquisition, delayed extinction and generalization of faces, as they represented socially relevant stimuli, concerning social phobics. Subjective indicators of conditioned response were valence, arousal and awareness. The startle reflex (recorded from left m. orbicularis oculi) was used as a measure of subcortical emotional processing. Bilaterally corrugator muscle activity (as an indicator of negative emotional facial response) and heart rate (as an indicator of general physiological activation) served as psychophysiological assessment of conditioning. Both groups were successfully conditioned as reflected by differential responses of all three subjective parameters. The results were consistent with the hypotheses. Compared to controls, social phobics showed an increased acquisition (startle latency and magnitude, heart rate deceleration), an extinction resistance (arousal, startle zero reactions, corrugator) as well as a generalization of CS types (arousal, awareness, startle latency, corrugator, heart rate deceleration). In addition the findings suggested that the emotional stimuli processing in participants are distinct. The social phobics in particular reacted to arousal, contingency awareness, startle and heart rate in acquisition (controls: corrugator) and to arousal, startle and corrugator in extinction (controls: awareness). There was no difference between groups regarding valence judgement.
