Abstract:
INTRODUCTION:Current practice guidelines recommend using Current Opioid Misuse Measure to screen aberrant opioid-related behaviors in chronic pain patients. Our aims were to translate, adapt and validate it to be used in Portuguese chronic pain patients. MATERIAL AND METHODS:Translation and cultural adaptation process followed guidelines and a model of principles for good practice. Adult chronic pain patients on opioid therapy, from one major hospital in Portugal, were invited to complete the translated version. Descriptive statistics, Cronbach's alpha, inter-item, item-total and intra-class correlation coefficients and principal components analysis were applied. RESULTS:Translation process was performed as planned and the validation sample was composed by 98 patients (median age = 62.5 years). Regarding internal consistency, a global Cronbach's alpha of 0.778 was obtained and item-total correlations of all items were above 0.20 with four exceptions. An intra-class correlation coefficient of 0.90 was found between test and retest. Regarding validity, all 17 items presented a content validity index above 0.80. Six principal components were extracted and explained 66.3% of the variance. DISCUSSION:The Portuguese version of Current Opioid Misuse Measure was properly translated, adapted and validated; showing good quality in terms of reliability and validity. This is the first instrument to screen aberrant opioid-related behaviors in Portuguese chronic pain patients. Consequently, it will aid and promote the identification of opioid misuse in these patients. CONCLUSION:The implementation of this questionnaire may reduce the incidence and morbimortality of opioid misuse among chronic pain patients and should improve chronic pain treatment in Portugal. :Introdução: Orientações atuais recomendam a utilização da Escala de Uso Indevido de Opióides para rastrear comportamentos aberrantes, relativos ao uso de opióides em dor crónica. Os objetivos foram a sua tradução, adaptação cultural e validação para a população portuguesa com dor crónica. Material e Métodos: O processo de tradução e adaptação cultural seguiu as recomendações. Adultos com dor crónica medicados com opióides, seguidos num hospital português de grande dimensão, foram convidados a completar a versão traduzida. Recurso a estatística descritiva, alfa de Cronbach, correlações inter-item, item-total, intra-classe, e análise de componentes principais. Resultados: A tradução decorreu conforme planeado e a amostra de validação foi de 98 doentes (mediana de idades = 62,5 anos). Relativamente à consistência interna, alfa Cronbach global = 0,778, correlações item-total dos itens > 0,20 (quatro exceções), e coeficiente de correlação intra-classe = 0,90 (entre teste e reteste). Relativamente à validade, os 17 itens apresentaram um índice de validade de conteúdo > 0,80. Extraíram-se seis componentes principais, que explicaram 66,3% da variância. Discussão: A versão portuguesa da Escala de Uso Indevido de Opióides foi adequadamente traduzida, adaptada e validada; demonstrando boa qualidade relativamente à confiabilidade e validade. Este é o primeiro instrumento para rastrear comportamentos aberrantes, relativos ao uso de opióides em portugueses com dor crónica. Consequentemente, ajudará e promoverá a identificação do uso indevido de opióides nestes doentes. Conclusão: A implementação deste questionário poderá reduzir a incidência e morbimortalidade do uso indevido de opióides em doentes com dor crónica, e deverá melhorar o tratamento da dor crónica em Portugal.
