12 item Allodynia Symptom Checklist/Brasil: cross-cultural adaptation, internal consistency and reproducibility

Abstract

Since there was no Portuguese questionnaire to evaluate cutaneous allodynia, which has been pointed out as a risk factor of migraine, we aimed to perform the cross-cultural adaptation of the 12 item Allodynia Symptom Checklist for the Brazilian population and to test its measurement properties. It consisted in six stages: translation, synthesis, back translation, revision by a specialist committee, pretest and submission the documents to the committee. In the pretest stage, the questionnaire was applied to 30 migraineurs of both sexes, who had some difficulty in understanding it. Thus, a second version was applied to 30 additional subjects, with no difficulties being reported. The mean filling out time was 3'36", and the internal consistency was 0.76. To test reproducibility, 15 other subjects filled out the questionnaire at two different times, it was classified as moderate (weighted kappa=0.58). We made available to Brazilian population an easy, quick and reliable questionnaire.Key words: translating, reproducibility of results, internal consistency, allodynia, migraine. RESUMOLevando em consideração que não há nenhum questionário em português disponível para avaliação da alodinia cutânea, sintoma que tem sido apontado como fator de cronificação da migrânea, o objetivo do trabalho foi realizar a adaptação transcultural do 12 item Allodynia Symptom Checklist para a população brasileira e testar suas características psicométricas. A adaptação foi realizada em seis estágios: tradução, síntese, retrotradução, revisão pelo comitê de especialistas, pré-teste e submissão dos documentos ao comitê. No estágio do pré-teste, foram aplicados 30 questionários em migranosos de ambos os sexos, que relataram dificuldades de compreensão. Por isso, foi criada uma segunda versão e aplicada a mais 30 sujeitos, não tendo sido relatadas dificuldades nesta versão. O tempo médio de preenchimento foi de 3'36", e a consistência interna encontrada foi 0,76. Para testar a reprodutibilidade, outros 15 sujeitos preencheram o questionário, em dois momentos, tendo sido a reprodutibilidade classificada como moderada (kappa ponderado=0,58). Portanto, disponibilizamos, para uso na população brasileira, um questionário fácil, rápido e confiável.

“…The ASC is a 12-item questionnaire that assesses for symptoms of cutaneous allodynia during headaches. A total ASC score ≥3 suggests the presence of cutaneous allodynia, with higher scores indicating greater severity (34,36). The PAQ consists of 16 questions that identify behaviors that are consistent with avoiding light, termed photophobia, or that are consistent with searching for light, described as photophilia.…”
