Previous issue date: 2014-03-07 / Exposure to potentially traumatic events in childhood and adolescence has been reported in approximately 50 % of children and adolescents. Symptoms as anxiety, depression, suicidal behavior, inappropriate sexual behavior and Posttraumatic Stress Disorder has been observed in traumatic exposed youth. Previous literature indicates that cognitive processing is related to the development, maintenance and aggravation of posttraumatic symptoms. Considering the variability of responses related to the traumatic events exposure in childhood and adolescence, early psychological is critical to the establishment of appropriate interventions. This dissertation consists of three empirical studies presented in the form of articles. The overall objective of this study was to conduct a cross-cultural adaptation and evaluate the psychometric properties of the Trauma Symptom Checklist for Children (TSCC) and the Child Posttraumatic Cognitions Inventory (CPTCI). The TSCC (Study 1) was properly adapted and demonstrated adequate internal consistency. The PCA yielded a six-factor solution, as proposed in the TSCC original structure. CFA was conducted to examine fit of the TSCC original six-factor solution. For all clinical scales (excepted Anger), were explored alternative models removing items that had a low correlation with other TSCC items and the latent construct. Despite rising rates of model fit, this study does not suggest changes in the structure of TSCC, considering that these are preliminary results of TSCC psychometric properties on a Brazilian sample. Good evidences of convergent validity were evidenced through correlations with the CDI and CBCL. Study 2 showed an adequate cross-cultural adaptation and content validation of CPTCI. The results of Study 3 showed high internal consistency and a two-component solution ( Permanent and disturbing change and Fragile person in a scary world ), Despite the similarity with the original structure of CPTCI, CFA showed that the original model did not fit well the data. Convergent validity evidences were obtained through correlations with TSCC and CDI. Findings highlighted by the three studies suggest that the TSCC and CPTCI are reliable and had adequate evidences of validity. / A exposi??o a eventos potencialmente traum?ticos na inf?ncia e adolesc?ncia tem sido reportada em aproximadamente 50% das crian?as e adolescentes. Sintomas de ansiedade, depress?o, comportamento suicida, comportamento sexual inadequado, Transtorno de Estresse P?s-Traum?tico, entre outros est?o associados ? exposi??o traum?tica nessa faixa et?ria. A literatura aponta que o processamento cognitivo disfuncional em rela??o ? situa??o traum?tica est? relacionado com o desenvolvimento, a manuten??o e o agravamento da sintomatologia p?s-traum?tica. Considerando a variabilidade das respostas relacionadas com a viv?ncia de eventos potencialmente traum?ticos na inf?ncia e adolesc?ncia e os fatores de risco implicados na manifesta??o de tais rea??es, a avalia??o precoce das rea??es p?s-traum?ticas ? fundamental para o estabelecimento de interven??es adequadas. Essa disserta??o de mestrado ? composta por tr?s estudos emp?ricos apresentados na forma de artigos. O objetivo geral do trabalho foi realizar a adapta??o transcultural e avaliar as propriedades psicom?tricas do Trauma Symptom Checklist for Children (TSCC) e do Child Posttraumatic Cognitions Inventory (CPTCI). O TSCC (Estudo 1) foi adequadamente adaptado e demonstrou apropriada consist?ncia interna. O instrumento manteve a mesma estrutura fatorial sugerida pelo estudo normativo, com uma solu??o de seis componentes, obtida atrav?s da An?lise de Componentes Principais (PCA). No entanto, a An?lise Fatorial Confirmat?ria (CFA), evidenciou uma baixa correla??o entre os itens e o construto latente, revelando pouca adequa??o do modelo. Foram explorados modelos alternativos com a retirada de itens que obtiveram baixas cargas fatoriais. Apesar do aumento dos ?ndices de adequa??o do modelo, este estudo n?o sugere modifica??es na estrutura do TSCC, considerando que esses s?o resultados preliminares de avalia??o das propriedades psicom?tricas do instrumento. Foram obtidas boas evid?ncias de validade convergente, evidenciadas atrav?s de correla??es entre com o CDI e a CBCL. O Estudo 2 demonstrou adequada adapta??o transcultural e valida??o de conte?do do CPTCI. Os resultados do Estudo 3, por sua vez, demonstraram elevada consist?ncia interna do CPTCI e uma estrutura fatorial com dois componentes ( Mudan?a permanente e perturbadora e Pessoa fr?gil em um mundo assustador ). Apesar da similaridade com a estrutura fatorial do estudo original, a CFA demonstrou que o modelo n?o se adequou aos dados do presente estudo, o que indica que o CPTCI parece comportar-se de maneira particular na realidade brasileira. Foram obtidas consistentes evid?ncias de validade convergente, atrav?s de correla??es com o TSCC e o CDI. Tomados em conjunto, os achados evidenciados pelos tr?s estudos sugerem que o TSCC e o CPTCI s?o instrumentos fidedignos e com adequadas evid?ncias de validade.
