“…Some of the 31 guidelines draw on expert recommendation by influential working parties (e.g. Guillemin, Bombardier, and Beaton 1993;Beaton et al 2000;Wild et al 2005;Acquadro et al 2008;Wild et al 2009) with authors representing specialised organisations (e.g. www.mapitrust.org/the patient-centred research company, and www.ispor.org/ the International Society for Pharmacoeconomics and Outcomes Research, ISPOR).…”

Objectives: To raise awareness and propose a good practice guide for translating and adapting any hearing-related questionnaire to be used for comparisons across populations divided by language or culture, and to encourage investigators to publish detailed steps. Design: From a synthesis of existing guidelines, we propose important considerations for getting started, followed by six early steps: (1) Preparation, (2, 3) Translation steps, (4) Committee Review, (5) Field testing and (6) Reviewing and finalising the translation. Study sample: Not applicable. Results: Across these six steps, 22 different items are specified for creating a questionnaire that promotes equivalence to the original by accounting for any cultural differences. Published examples illustrate how these steps have been implemented and reported, with shared experiences from the authors, members of the International Collegium of Rehabilitative Audiology and TINnitus research NETwork. Conclusions: A checklist of the preferred reporting items is included to help researchers and clinicians make informed choices about conducting or omitting any items. We also recommend using the checklist to document these decisions in any resulting report or publication. Following this step-by-step guide would promote quality assurance in multinational trials and outcome evaluations but, to confirm functional equivalence, large-scale evaluation of psychometric properties should follow.

“…The steps taken for the adaptation were in accordance with the guidelines proposed by Guillemin et al 16 , and have been replicated by several authors [17][18][19][20] . First, the entire original scale was translated into Brazilian Portuguese by two independent Portuguese-speaking translators who were aware of the objectives of the study.…”

“…Every item was modified, after the original scale's author consent (A.E.Lang, personal communication). This remodeling took in account the need to produce a scale able to measure exactly the same as the original scale 16,19,20 . To ensure it, the newly revised scale went through re-evaluation of semantic and idiomatic/cultural features by two judges, one of whom was a Portuguese university teacher.…”

Cervical dystonia (CD) is a prevalent and incapacitating movement disorder which needs a thorough clinical evaluation of every patient to better tailor treatment strategies. In Brazil, there are no validated CD scales that measure the burden of dystonia. The aim of our study was to translate and adapt the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) to Brazilian Portuguese. After translation and back-translation according to international methods, a pre-test was carried out with 30 patients. Patients under 8 years of formal schooling had severe difficulty in understanding the whole scale. The scale went through a remodeling process, without loss of its conceptual and semantic properties. The new scale was tested in 15 patients, with good understanding scores. We are now in the process of validation of the adapted scale. Key words: cervical dystonia, scales, cross-cultural adaptation.Adaptação transcultural da escala de distonia cervical de Toronto (TWSTRS) para o português RESUMO Distonia cervical (DC) é um transtorno de movimento prevalente e incapacitante, sendo uma avaliação global e consistente de cada paciente necessária para a melhor intervenção diagnóstica e terapêutica. No Brasil, não há escalas validadas para avaliar o impacto da DC. O objetivo deste trabalho foi traduzir e adaptar uma escala mundialmente conhecida e usada, a Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) para o português. Após a tradução e retro-tradução da escala segundo as normas e critérios internacionais, realizamos o pré-teste com 30 pacientes, sendo que o completo entendimento da escala ficou prejudicado nos pacientes com escolaridade abaixo de 8 anos. Tornou-se necessária a re-adaptação da escala, com modificação de alguns elementos, tentando manter-se sua integridade conceitual e semântica. Após pré-teste adicional com 15 pacientes, verificou-se que a escala foi completamente entendida por praticamente todos os pacientes. A validação da escala está em andamento. Palavras-chave: distonia cervical, escalas, adaptação trans-cultural.

“…A recent study (19) reviewing the translation and cultural adaptation of instruments notes the existence of different designations to name the process of adaptation, and also the lack of consensus about the recommended stages for cultural adaptation. The authors conclude, however, that it was not possible to observe evidence to favor a particular translation method, thus recommending a multiple-stage approach to guarantee the quality of the process.…”

The objective of the present study was to perform the cultural adaptation of The Environmental Stressor Questionnaire -ESQ for the Brazilian Portuguese, as well as to verify its reliability and validity. In order to ensure the equivalence between the original instrument and the Brazilian version, all methodological steps recommended in the literature regarding cultural adaptation were followed. The Brazilian version of the ESQ was applied to 106 ICU patients in two hospitals (public and private) in the interior of São Paulo State. Reliability was evaluated in relation to internal consistency and stability (test e retest) and the convergent validity was determined by the correlation between ESQ and generic questions about ICU stress. Reliability was satisfactory with Cronbach's Alfa = 0,94 and stability (ICC=0,861; IC95% 0,723; 0,933). ESQ total score displayed strong correlation with the generic questions about stress (r=0,70; p<0,0001), thus confirming the convergent validity. The conclusion was that the ESQ adapted for Brazilian culture is a reliable instrument for evaluation of stressors in the ICU. KEY WORDS RESUMENEste estudio tuvo como objetivo realizar la adaptación cultural del Environmental Stressor Questionnaire (ESQ) a la lengua portuguesa de Brasil y verificar su confiabilidad y validez. Fueron empleadas las etapas metodológicas recomendadas por la bibliografía para la adaptación cultural. La versión brasileña del ESQ fue aplicada a 106 pacientes de Unidad de Terapia Intensiva (UTI) de dos hospitales, público y privado, del interior del estado de San Pablo, Brasil. La confiabilidad fue evaluada respecto de la consistencia interna y la estabilidad (test y retest); la validez convergente fue verificada a través de la correlación entre el ESQ y pregunta genérica acerca de estrés en UTI. La confiabilidad fue satisfactoria, con Alfa de Cronbach = 0,94 y Coeficiente de Relación Intraclase = 0,861 (IC 95%; 0,723; 0,933). Se constató correlación entre el puntaje total del ESQ y la pregunta genérica sobre estrés (r = 0,70), confirmado la validez convergente. La versión brasileña del ESQ se mostró como una herramienta confiable y válida para la evaluación de estresores en UTI. DESCRIPTORES
