Abstract

Background and objectives: Neuropathic pain is common in the general population worldwide and Brazil. The painDETECT questionnaire is a notable instrument for screening on neuropathic pain. A Brazilian version of the painDETECT is necessary to broaden the possibilities of identification of neuropathic pain in the Brazilian population for the proper diagnosis and treatment. The current study aimed to perform the translation and cross-cultural adaptation of the painDETECT into the Portuguese language of Brazil.

Methods: A cross-cultural adaptation study was conducted in 11 stages according to standard procedures. Descriptive statistics were performed. The internal consistency of the questionnaire was assessed using Cronbach’s Alpha test (a).

Results: Four translators, 10 experts, and 30 patients participated in the study. The expert committee adapted five out of nine items (item 2, 3, 6, 8, and 10) to the Brazilian context. The pretesting phase showed good internal consistency (a = 0.74) for the nine items, including the pain pattern and the body chart domains. The Cronbach’s a of the instrument with seven descriptor items of pain was 0.83.

Conclusions: The painDETECT was cross-culturally adapted into a Brazilian context and can be used to identify neuropathic components in pain of Brazilian patients.

Clinical implications: PainDETECT is available for Brazilians to identify neuropathic components in pain.

Resumo

Justificativa e objetivo: Os avanços na técnica cirúrgica, no acompanhamento pós-operatório. A dor neuropática é comum na população em geral em todo o mundo
e no Brasil. O questionário painDETECT é um instrumento notável para rastreamento da dor neuropática. Uma versão brasileira do painDETECT é necessária para ampliar as possibilidades de identificação da dor neuropática na população brasileira para o diagnóstico e tratamento adequados. O presente estudo teve como objetivo realizar a tradução e adaptação transcultural do painDETECT para a língua portuguesa do Brasil. 

Métodos: Um estudo de adaptação cultural foi conduzido em 11 etapas de acordo com os procedimentos padrão. Estatísticas descritivas foram realizadas. A consistência interna do questionário foi avaliada por meio do teste Alfa de Cronbach (α). 

Resultados: Quatro tradutores, 10 especialistas e 30 pacientes participaram do estudo. O comitê de especialistas adaptou cinco dos nove itens (itens 2, 3, 6, 8 e 10) ao contexto brasileiro. A fase de pré-teste apresentou boa consistência interna (α = 0,74) para os nove itens, incluindo o padrão de dor e os domínios do gráfico corporal. O α de Cronbach do instrumento com sete itens descritores de dor foi de 0,83.

Conclusões: O painDETECT foi adaptado culturalmente para o contexto brasileiro e pode ser usado para identificar componentes neuropáticos na dor de pacientes brasileiros. Implicações clínicas: PainDETECT está disponível para que brasileiros identifiquem componentes neuropáticos na dor.
