O Transtorno de Ansiedade Social (TAS) consiste em um medo acentuado e persistente de situações sociais ou de desempenho nas quais o indivíduo poderia sentir vergonha. Dentre os transtornos de ansiedade, o TAS é um dos mais prevalecentes, sendo considerado o quinto transtorno mais incapacitante, contudo, a busca por tratamento é muito baixa. Diferentes estudos clínicos randomizados evidenciam que a TCCG apresenta resultados satisfatórios e duradouros, sendo considerada padrão ouro de intervenção para TAS, porém, ainda assim, uma parcela de pacientes com TAS não respondem ao tratamento. Assim sendo, o objetivo deste trabalho foi investigar o efeito de uma intervenção em grupo de exposição com alto custo social em pacientes com TAS sobre variáveis psicológicas e também sobre a qualidade de memória. A intervenção utilizada nesse estudo foi a proposta por Hofmann e Otto (2008). Dentre as variáveis psicológicas estudadas foram avaliadas mudanças em sintomas de ansiedade social, ansiedade, medo da avaliação negativa, esquiva e desconforto social, depressão e sintomas de transtornos psiquiátricos comuns. Participaram desse estudo 58 adultos, compondo três grupos experimentais diferentes: o grupo de comparação sem TAS, que consiste em participantes sem sintomas clínicos, o grupo de comparação com TAS, que são participantes portadores de TAS os quais não realizaram a intervenção durante a pesquisa (grupo lista de espera) e o grupo de portadores de TAS participaram da intervenção (grupo TCCG). Um pesquisador independente ao estudo realizou a distribuição aleatória dos participantes com TAS entre os grupos TCCG e lista de espera. Foram realizadas avaliações no pré e pós-teste através do Inventário de Fobia Social (SPIN), Inventários de Ansiedade e Depressão de Beck (BAI e BDI-II), Escala de Medo da Avaliação Negativa (FNE), Escala de Esquiva e Desconforto Social (SADS), Questionário sobre a saúde do paciente (PHQ-9), Questionário de Autorrelato (SRQ) e teste de falsas memórias. Assim, os resultados encontrados evidenciam que a intervenção alcançou redução significativa nos sintomas de ansiedade social, ansiedade geral, depressão e sintomas de transtornos mentais comuns, mostrando que foi uma intervenção efetiva. Além disso, os escores relacionados à ansiedade geral, depressão e sintomas de transtornos mentais comuns, após a intervenção foram equiparados com o escore obtidos pelo grupo de participantes saudáveis, evidenciando a excelente eficácia do processo de intervenção. A eficácia também pode ser constatada a partir da mensuração do tamanho de efeito grande encontrado no estudo relacionado ao principal instrumento de avaliação de TAS utilizado (SPIN), ou seja, esse estudo evidenciou que a forma psicoterápica utilizada atingiu o objetivo esperado da intervenção considerada padrão ouro. No que concerne às medidas relacionadas à qualidade de memória, a hipótese inicial relacionava-se à teoria de que os indivíduos ansiosos sociais apresentariam um número maior de falsas memórias e/ou uma redução de memórias verdadeiras, porém essa hipótese não foi confirmada. / Social Anxiety Disorder (SAD) consists of a marked and persistent fear of social or performance situations in which the individual could feel shame. Among the anxiety disorders, SAD is one of the most prevalent, considered the fifth most disabling disorder, however, the search for treatment is very low. Different randomized clinical trials show that Cognitive-Behavioral Group Therapy (CBGT) presents satisfactory and long-lasting results, which is considered the gold standard of intervention for SAD, however, a portion of patients with SAD do not respond to treatment. Thus, the objective of this study was to investigate the effect of a group intervention related to high social cost exposure in patients with SAD about psychological variables and memory quality. The intervention used in this study was proposed by Hofmann and Otto (2008). Among the psychological variables studied changes in symptoms of social anxiety, anxiety, fear of negative evaluation, avoidance and social discomfort, depression and symptoms of common psychiatric disorders were evaluated. Fifty-five adults participated in this study, composing three different experimental groups: the comparison group without SAD, which consists of participants without clinical symptoms, the comparison group with SAD, participants with SAD who did not receive intervention during the research (Waitlist control condition), and the group of SAD patients who participated in the intervention. An independent researcher to study distributed randomly the participants with SAD between CBGT or Waitlist condition. Assessments were made at pre and post-test using Social Phobia Inventory (SPIN), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), Fear of Negative Evaluation (FNE), Social Avoidance and Distress Scale (SADS), Patient Health-Questionnaire (PHQ-9), Self-Report Questionnaire (SRQ), and false memories test in the three groups. The results showed that the intervention achieved a significant reduction in the symptoms of social anxiety, general anxiety, depression and symptoms of common mental disorders, showing that it was an effective intervention. In addition, the scores related to general anxiety, depression and common mental disorder symptoms after the intervention were similar to the scores obtained by the group of healthy participants, evidencing the excellent efficacy of the intervention process. Efficacy can also be seen from the measurement of the large effect size found in the study evaluated by the main evaluation instrument of SAD used (SPIN), this study achieved the expected goal of the gold standard considered intervention. Concerning measures related to memory quality, the initial hypothesis was that social anxious individuals would present a greater number of false memories and / or a reduction of true memories, but this hypothesis was not confirmed.

Objetivos: Estudar a confiabilidade e validade de uma versão brasileira dos módulos Episódio Depressivo Maior (EDM) e Transtorno de Ansiedade Generalizado (TAG) do Mini International Neuropsychiatric Interview TRACKING (MINI-TRACKING); comparar a evolução de pacientes com diagnóstico de EDM e TAG seguidos por equipes de Estratégia de Saúde da Família (ESF) com acesso ao modelo de Cuidado Colaborativo (CC) em Saúde Mental versus um grupo de pacientes seguidos por equipes sem acesso ao CC. Metodologia: O estudo envolveu quatro equipes de ESF vinculadas à Faculdade de Medicina de Ribeirão Preto (FMRP), sendo duas com acesso ao CC e duas sem CC. Um total de 147 pacientes foram entrevistados com o objetivo de rastrear transtornos mentais com a aplicação do WHO-5 e do COOP-WONCA Quadro Sentimentos. Após a confirmação diagnóstica de EDM e/ou TAG, com a entrevista MINI, 42 pacientes foram selecionados e concordaram em participar da pesquisa. Estes pacientes foram acompanhados por doze meses por um médico de família (MF), que aplicou periodicamente a cada oito a doze semanas os módulos EDM e/ou TAG do MINI-TRACKING. Para avaliação da fidedignidade e da validade concorrente, um psiquiatra (cego quanto ao diagnóstico do MF e quanto a qual equipe seguia o paciente) aplicou, com intervalo máximo de 72h do MF, os mesmos módulos do MINI-TRACKING, o PHQ-9 e/ou o GAD-7. Resultados: Não foi encontrada diferença estatisticamente significativa entre os pacientes das equipes com e sem CC no que se refere as características clínicodemográficas. Os itens individuais dos dois módulos do MINI-TRACKING mostraram boa fidedignidade inter-avaliadores (Kappa entre 0,78 e 0,98), bem como seus escores totais (Coeficiente Intra-classe de 0,996 e 0,993 para EDM e TAG, respectivamente). Os módulos EDM e TAG mostraram também boa validade concorrente com as escalas PHQ-9 e GAD-7 (coeficiente de Pearson 0,994 e 0,976, respectivamente). Trinta pacientes (quinze de equipes com CC e 15 de equipes sem CC) completaram as cinco avaliações no decorrer de um ano de seguimento. A ANOVAmr destes pacientes mostrou diferenças significativas no fator tempo e na interação tempo x intervenção, com diminuição significativamente maior dos escores do MINI-TRACKING nos pacientes seguidos pelas equipes com CC. Conclusão: Os módulos EDM e TAG do MINI-TRACKING são uma opção confiável para o seguimento de pacientes com estes diagnósticos. Este estudo também mostrou, de forma preliminar, que o CC em saúde mental é uma estratégia eficaz na redução de sintomas dos pacientes com EDM e TAG na Atenção Primária. / Objectives: To study the reliability and validity of a Brazilian version of the Mini International Neuropsychiatric Interview - TRACKING (MINI-TRACKING) modules for Major Depressive Episode (MDE) and Generalized Anxiety Disorder (GAD); To compare the outcomes of patients diagnosed with MDE and GAD followed by teams of the Family Health Strategy (FHS) with access to the Mental Health Collaborative Care model (CC) versus a group of patients followed by teams without access to CC. Methodology: The study involved four FHS teams of the Faculty of Medicine of Ribeirão Preto (FMRP), two of them with access to CC and two without it. A total of 147 patients were tracked for mental disorders with the application of the WHO-5 and the COOP-WONCA Chart Feelings. After confirming the diagnosis of MDE and/or GAD using the MINI interview, 42 patients were selected and agreed to participate. These patients were followed for twelve months by a family physician (FP), who applied regularly every eight to twelve weeks the MDE and/or the GAD MINI-TRACKING modules. To assess the reliability and concurrent validity, a psychiatrist (blind to the diagnosis and to which team the patient was followed) also applied the same modules of the MINI-TRACKING, the PHQ-9 and/or the GAD-7, with a maximum interval of 72 hours of the FP. Results: There was no statistically significant difference between the patients with and without CC teams regarding demographic and clinical characteristics. The individual items of the two MINI-TRACKING modules showed good inter-rater reliability (kappa between 0.78 and 0.98), as well as their total scores (Intra-class coefficient of 0.996 and 0.993 for MDE and GAD, respectively). The MDE and GAD modules also showed good concurrent validity with PHQ-9 and GAD-7 scales (Pearson coefficient 0.994 and 0.976, respectively). Thirty patients (fifteen with CC and 15 without CC) completed the five assessments during one year of follow up. The repeated-measures analysis of variance (rmANOVA) showed significant differences in the time factor and the interaction time x intervention, decrease significantly higher of the MINI-TRACKING scores in the patients followed by teams with CC. Conclusion: MINI-TRACKING MDE and GAD modules are a reliable option for following patients with these diagnoses. This study also showed, preliminarily, that CC in Mental Health is an effective strategy in reducing symptoms in Primary Care patients with MDE and GAD.

This study investigated the utility of the Personality Assessment Inventory (PAI) for diagnosing and discriminating between Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) with university counseling center clients. Participants were 1541 male and female students who received services at a student counseling center at a large university. Participants were classified as MDD, GAD, or Other Diagnosis (OD) based on the diagnosis determined by the treating clinician, and PAI profiles were compared between the three groups. The PAI Structural Summary-Revised contains Diagnostic Consider Clusters (DCC) that were designed to identify PAI scales/subscales that are typically elevated or suppressed when a particular disorder is present. The DCC’s for MDD and GAD were examined and the results demonstrated that the criteria for the DCC for MDD were met by 2.2% of the MDD group, and the criteria for the DCC for GAD were met by 3.8% of the GAD group. A discussion of these findings is offered, and the appropriateness of using the DCC’s for the purpose of diagnosis with any population is questioned. Additionally, DCC’s for MDD and GAD for use with university counseling center clients are proposed. Finally, discriminant analysis (DA) was employed to develop various discriminant functions that can be used to classify individual PAI profile data into specific diagnostic groups. In particular, one discriminant function was created that is capable of examining any PAI profile, and classifying it as either MDD or OD. A second discriminant function was produced that can analyze any PAI profile and categorize it as either GAD or OD. The final discriminant function was developed to evaluate a PAI profile that represents either MDD or GAD and determine which diagnosis is appropriate. Each discriminant function was shown to accurately predict the associated diagnoses. A discussion of the various predictor variables is offered. Taken together, these results support the use of the PAI for diagnosing and discriminating between MDD and GAD with university counseling center clients.

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.

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.

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.

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.

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.

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.

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.
