Background Both Psychodynamic Group Therapy (PGT) and clonazepam are used as treatment strategies in reducing symptoms of generalized social anxiety disorder (GSAD). However, many individuals remain symptomatic after treatment with PGT or clonazepam. Method Fifty-eight adult outpatients with a diagnosis of GSAD according to DSM-IV were randomized to 12 weeks PGT plus clonazepam or clonazepam. The Clinical Global Impression-Improvement (CGI-I) Scale was the primary efficacy measure. Secondary efficacy measures included the Liebowitz Social Anxiety Scale (LSAS) total score, the World Health Organization Instrument to Assess Quality of Life-Bref (WHOQOL-Bref) Scale and the Beck Depression Inventory (BDI). Results CGI-I data from 57 patients (intent-to-treat population) showed that patients who received PGT plus clonazepam presented significantly greater improvement than those who received clonazepam (p=0.033). There were no significant differences between the two groups in the secondary efficacy measures. Conclusion/Discussion Our study suggests that the combination of PGT with clonazepam may be a promising strategy for the treatment of GSAD, regarding gains in the global functioning. However the present study failed to detect more specific changes in social anxiety symptomatology between the two groups.

Objective: This study aims to describe the design, methods and sample characteristics of the Multidimensional Evaluation and Treatment of Anxiety in Children and Adolescents -the PROTAIA Project. Method: Students between 10 and 17 years old from all six schools belonging to the catchment area of the Primary Care Unit of Hospital de Clínicas de Porto Alegre were included in the project. It comprises five phases: (1) a community screening phase; (2) a psychiatric diagnostic phase; (3) a multidimensional assessment phase evaluating environmental, neuropsychological, nutritional, and biological factors; (4) a treatment phase, and (5) a translational phase. Results: A total of 2,457 subjects from the community were screened for anxiety disorders. From those who attended the diagnostic interview, we identified 138 individuals with at least one anxiety disorder (apart from specific phobia) and 102 individuals without any anxiety disorder. Among the anxiety cases, generalized anxiety disorder (n = 95; 68.8%), social anxiety disorder (n = 57; 41.3%) and separation anxiety disorder (n = 49; 35.5%) were the most frequent disorders. Conclusion:The PROTAIA Project is a promising research project that can contribute to the knowledge of the relationship between anxiety disorders and anxiety-related phenotypes with several genetic and environmental risk factors. Resumo Objetivo: o objetivo deste estudo é descrever o desenho, os métodos e as características amostrais da Avaliação Multidimensional e Tratamento da Ansiedade em Crianças e Adolescentes -Projeto PROTAIA. Método: Escolares entre 10 e 17 anos de todas as escolas pertencentes à área de abrangência da unidade de atenção primária do Hospital de Clínicas de Porto Alegre foram incluídos no projeto. O projeto compreende cinco fases: 1) triagem comunitária; 2) diagnóstico psiquiátrico; 3) avaliação multidimensional, incluindo fatores ambientais, neuropsicológicos, nutricionais e marcadores biológicos; 4) tratamento; e 5) fase translacional. Resultados: Um total de 2.457 sujeitos foram triados para transtornos de ansiedade na comunidade. Dos indivíduos que compareceram à avaliação diagnóstica, 138 foram detectados com ao menos um transtorno de ansiedade (excluindo fobia específica) e 102 indivíduos sem nenhum transtorno de ansiedade. Dentre os casos de ansiedade, o transtorno de ansiedade generalizada (n = 95; 68,8%), transtorno de ansiedade social (n = 57; 41,3%) e o transtorno de ansiedade de separação (n = 49; 35,5%) foram os mais frequentes. Conclusão: O projeto PROTAIA é um projeto de pesquisa promissor que pode contribuir para o entendimento da relação entre transtornos de ansiedade e fenótipos relacionados à ansiedade com vários fatores de risco, tanto genéticos quanto ambientais.

Background: Although cognitive-behavioral therapy (CBT) is established as a first line treatment for anxiety disorders in children and adolescents, there is little evidence about the effectiveness of CBT protocols in cases identified in the community in low and middle income countries (LaMICs). Aims: To evaluate the effectiveness of group CBT protocol for youths with anxiety disorders identified in a community sample in LaMICs. Method: A total of 14 sessions of group CBT for youths and 2 concurrent sessions for parents based on Kendall's Coping Cat program were offered. Participants were selected from a crosssectional community study; 45 subjects fulfilled inclusion criteria and 28 agreed to participate in the open clinical trial. Treatment effectiveness was evaluated with standard clinical, selfand parent-rated measures of anxiety, depression, externalizing symptoms and quality of life (QoL). Results: Twenty youths completed the protocol. All scales showed an improvement of anxiety and reduction in externalizing symptoms over time, with a moderate to large effect size (d = 0.59 to 2.06; p < .05), but not in depressive symptoms or QoL. Conclusions: Consistent with previous evidence, group CBT is effective in treating anxiety disorders in youths. Results encourage further randomized clinical trials using CBT protocols adapted and developed to be used in LaMICs.

Psychodynamic Group Therapy (PGT) and clonazepam are strategies to reduce symptoms of generalized social anxiety disorder (GSAD). The addition of PGT might lead to changes in defense styles. The objective of this study is to examine changes in defense styles when comparing clonazepam to psychodynamic group therapy plus clonazepam in GSAD during 12 weeks. Fifty-seven patients that met DSM-IV criteria for GSAD participated. social anxiety disorder symptoms were evaluated with the Liebowitz Social Anxiety Scale, and defense styles with the Defense Style Questionnaire. All defense styles changed overtime for both groups, especially mature defense style, which increased independently of the treatment allocation group. Regression analyses found that overtime there was a reduction in neurotic defenses in the combined group, whereas there was an increase in the clonazepam group. Neurotic defense style can change toward greater adaptiveness with the addition of PGT to clonazepam in GSAD, even in 12 weeks.

The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigenetically controlled faulty embryonic development of structures of ectodermal origin like brain and skin. This may disturb neurodevelopment that in turn may cause these subjects to be at increased risk for the development of schizophrenia and related disorders. The precise confirmation of this theory, at least in some cases, will provide further understanding of these illnesses, allowing easy and inexpensive identification of subjects at risk and providing guidelines for the development of new pharmacological interventions for early treatment and even for primary prevention of the illness.

O presente artigo inicia pela revisão dos modelos cognitivos e dos princípios gerais da terapia cognitivocomportamental (TCC) no transtorno de ansiedade social. Em seguida, os autores propõem um exercício sistemático a ser utilizado especialmente durante as sessões da TCC de psicoeducação e reestruturação cognitiva. Tendo por base o ciclo da ansiedade social disfuncional, o qual colabora para a manutenção dos sintomas de ansiedade social, paciente e terapeuta trabalham ativamente buscando um ciclo mais funcional, o ciclo alternativo da ansiedade social.
