RESUMO
High rates of co-occurrence of mental disorders have been hypothesized to represent a result of common susceptibility to overall psychopathology. The purpose of this study is to test the hypothesis that commonalities among psychiatric disorders might be partially driven by sharable perinatal and neonatal environmental factors for mental disorders. Participants were 6-14 years of age children and their parents. Primary caregivers provided data on perinatal and neonatal information assessed retrospectively (n = 2231). Psychiatric disorders diagnoses were assessed using the Development and Well Being Behavior Assessment (DAWBA). We used bifactor models to disentangle common from dissociable aspects of psychopathology. These models allow modeling psychiatric disorders as the result of a common domain of psychopathology (p-factor) and three dissociable domains (fear, distress, and externalizing symptoms). Associations were tested using linear and tobit regression models. The p-factor was associated with male sex, low socioeconomic status, gestational smoking, gestational drinking, low levels of maternal education and presence of mental disorder in the mother. Associations with specific factors also emerged suggesting some risk factors might also have some role for fear, distress and externalizing factors. Our study supports the hypothesis that overall susceptibility to psychopathology might be partially driven by sharable perinatal and neonatal factors.
RESUMO
Abstract Objective To describe the cross-cultural adaptation of the Anger Rumination Scale (ARS) for use in Brazil. Methods The cross-cultural adaptation followed a four-step process, based on specialized literature: 1) investigation of conceptual and item equivalence; 2) translation and back-translation; 3) pretest; and 4) investigation of operational equivalence. Results A final Brazilian version of the instrument (ARS-Brazil) was defined and is presented. Pretest results revealed that the instrument was generally well understood by adults as well as indicated a few modifications that were included in the final version presented here. Conclusion The Brazilian Portuguese version of the ARS seems to be very similar to the original ARS in terms of conceptual and item equivalence, semantics, and operational equivalence, suggesting that future cross-cultural studies may benefit from this early version. As a result, a new instrument is now available for the assessment of rumination symptoms of anger and irritability for adults in community, clinical, and research settings.
Resumo Objetivo Descrever a adaptação transcultural da Escala de Ruminação de Raiva (Anger Rumination Scale, ARS) para uso no Brasil. Método A adaptação transcultural seguiu um processo de quatro etapas baseado em literatura especializada: 1) investigação da equivalência conceitual e dos itens; 2) tradução e retrotradução; 3) pré-teste; e 4) investigação da equivalência operacional. Resultados Uma versão final brasileira do instrumento, denominada ARS-Brasil, foi obtida e é apresentada. Os resultados do pré-teste demonstraram que a escala foi predominantemente bem entendida entre adultos, e indicaram algumas modificações que foram incluídas na versão final. Conclusão A versão da ARS adaptada para o português brasileiro mostra-se muito similar à versão original da ARS no que diz respeito à equivalência conceitual e dos itens, semântica e equivalência operacional, sugerindo que futuros estudos transculturais poderiam se beneficiar desta primeira versão. Como resultado, um novo instrumento está agora disponível para a avaliação de sintomas de ruminação da raiva e da irritabilidade para adultos, em contextos comunitário, clínico e de pesquisa.
