Cross-cultural adaptation to Brazil of Medication Adherence Rating Scale for psychiatric patients

Abstract

objective: The purpose of this research was to make a cross-cultural adaptation of the Medication Adherence Rating Scale (MARS) for psychiatric patients to the Brazilian context. Methods: The procedure consisted of four phases: translation of the original scale, backtranslation, review by an Expert Committee and Pre-test study with a patients' sample. results: The Expert Committee corrected the items' translation when necessary and modified the scale administration format and its instructions from self-report to face-to-face interview form in order to ensure easy understanding by the target population. During Pre-test, the instructions and most of the items were properly understood by patients, with the exception of three of them which had to be changed in order to ensure better understanding. The Pretest sample was composed by 30 psychiatric patients, with severe and persistent disorders mainly single (46.7%), female (60.0%), with a mean age of 43.8 years old and an average of five years of education. conclusion: The Brazilian version of MARS scale is now adapted to the Brazilian Portuguese language and culture and is easily understood by the psychiatric target population. It is necessary to do further research to evaluate the scale psychometric qualities of validity and reliability in order to use it in Brazil. reSUMo objetivo: Esta pesquisa teve como objetivo fazer a adaptação transcultural do instrumento Medication Adherence Rating Scale (MARS) para pacientes psiquiátricos no contexto brasileiro. Métodos: O procedimento incluiu quatro fases: tradução da escala original, retradução, revisão por Comissão de Especialistas e Pré-teste com uma amostra de pacientes. resultados: A Comissão de Especialistas adequou a redação dos itens e das instruções e mudou a forma de aplicação da escala, que passou de autoaplicação para o formato de entrevista, visando à maior facilidade de compreensão pela população-alvo. No Pré-teste, as instruções e a maioria dos itens foram bem compreendidas, com exceção de três questões que apresentaram palavras que suscitaram dúvidas nos participantes, tendo sido modificadas para melhor compreen são. A amostra do pré-teste foi composta de 30 pacientes psiquiátricos, com transtornos graves e persistentes, majoritariamente solteiros (46,7%), do sexo feminino (60,0%) com idade média de 43,8 anos e cinco anos de escolaridade, em média. conclu-

Cross-cultural adaptation, reliability, and content validity of the Brief Negative Symptom Scale (BNSS) for use in Brazil

“…Using the probe technique led us to replace some ambiguous words for others easily understood by the target population, just as in another Brazilian article on cross-cultural adaptation 22 . It is worth noticing that the content validation carried out by the target population differed in other cross-cultural adaptation studies conducted in Brazil, as they applied a semantic assessment tool [22][23][24] . However, schizophrenia is associated with significant cognitive deficits 25,26 , making it difficult to execute/perform this assessment.…”

Cross-cultural adaptation of the drug-taking confidence questionnaire drug version for use in Brazil

“…However, some methodological studies of cross-cultural adaptation and translation do not report the sociodemographic of their targeted population and focus solely on the gender [44] and other aspects of the study [45]. These studies demonstrate that the emphasis on methodological studies is the same as that of the method used in cross-cultural adaptations [46–48], which, in the present study, was the guideline by Beaton et al (2007) [30].…”

Adaptação transcultural do Questionário sobre Conhecimento de Doenças Sexualmente Transmissíveis para o português brasileiro

“…Em relação à literatura, os artigos brasileiros que mencionam os preservativos desse material são de mais de 15 anos atrás 41,42 e apenas apresentam dados sobre esse material para demonstrar a evolução da produção dos preservativos. É importante salientar que os instrumentos, além de serem culturalmente adequados para determinada população, precisam ser adequados para a vida no dia a dia 43 . A sífilis é a terceira DST mais prevalente no Brasil 1 e essa prevalência está aumentando nos últimos anos 44 .…”
