Escala Razões para Fumar Modificada: tradução e adaptação cultural para o português para uso no Brasil e avaliação da confiabilidade teste-reteste

Abstract

Objective: To translate the Modified Reasons for Smoking Scale (MRSS) to Portuguese, to submit it to crosscultural adaptation for use in Brazil and to evaluate the test-retest reliability of the translated version. Methods: An English-language version of the MRSS was translated to Portuguese by Brazilian doctors who have thorough knowledge of the English language. A consensus version was produced by a multidisciplinary group including two pulmonologists, a psychiatrist and a psychologist. This version was back-translated to English by an American translator. Cross-cultural adaptation of the final version was evaluated in a sample of 20 healthy smokers. Testretest reliability was evaluated by applying the translated version of the scale in 54 healthy smokers on two distinct occasions, 15 days apart. Results: This translated version of the MRSS was well understood by 95% of the smokers, indicating excellent cross-cultural equivalence. The degree of reliability of the answers in two different occasions was almost perfect for two questions, substantial for ten questions, moderate for eight questions, and low for one question. The intraclass correlation coefficients of the motivational factors obtained on the two different occasions, calculated according to previously published theoretical models, were higher than 0.7 for six of the seven subscales. Conclusions:The Portuguese-language version of the MRSS shows satisfactory cross-cultural equivalence and test-retest reliability. It can be a useful tool in the evaluation and treatment of smokers in Brazil.Keywords: Smoking cessation; Scales; Translations; Validation studies. ResumoObjetivo: Traduzir, fazer a adaptação cultural e testar a confiabilidade teste-reteste de uma versão em língua portuguesa da Escala Razões Para Fumar Modificada (ERPFM) para uso no Brasil. Métodos: Uma versão em língua inglesa da ERPFM foi traduzida por médicos brasileiros com profundo conhecimento sobre a língua inglesa. Uma versão de consenso foi obtida por grupo multidisciplinar composto por dois pneumologistas, um psiquiatra e um psicólogo. Essa versão foi traduzida de volta ao inglês por um tradutor americano. A avaliação da adaptação cultural da versão final foi efetuada em uma amostra de 20 fumantes saudáveis. A avaliação da confiabilidade teste-reteste foi feita pela aplicação da versão traduzida da escala em 54 fumantes saudáveis em duas ocasiões separadas por 15 dias. Resultados: Essa versão traduzida da ERPFM exibiu excelente identidade cultural, sendo bem compreendida por 95% dos fumantes. Os graus de concordância das respostas em duas ocasiões distintas foram quase perfeito para duas questões, substancial para dez questões, moderado para oito questões e discreto para uma questão. Os valores dos coeficientes de correlação intraclasse dos fatores motivacionais em duas ocasiões, empregando-se modelos teóricos previamente publicados, foram superiores a 0,7 em seis dos sete domínios. Conclusões: A presente versão da ERPFM exibe identidade cultural e confiabilidade teste-retest...

Cessação de tabagismo: desafios a serem enfrentados

“…This is the first Brazilian study to be published using this scale, which has been recently validated for the Portuguese language by the same authors. 8 The authors based the importance of the study 7 on the fact that the reasons leading individuals to smoke are not restricted to nicotine dependence, since there are also behavioral and psychosocial components which have not been well understood yet and whose dimension could be better measured by this scale, thus serving as an additional supportive component for the programs of smoking cessation. The study revealed that the scale presented adequate factorial structure and psychometric properties, showing the lowest scores in the following domains: dependence, tension reduction/relaxation, and hand-mouth activity, which were significantly associated with lower scores on the Fagerström nicotine dependence test.…”

“…3 Ridker et al suggested the inclusion of CRP in a clinical score (Reynolds Risk Score) in order to improve the stratification of cardiovascular risk. 8 However, recent studies using new statistical methods to test the presence or absence of the additional utility of biomarkers compared the traditional risk factors have not confirmed the usefulness of CRP as a risk marker. 9,10 Currently, it is well known that the definition of the traditional measures of association, such as odds ratios or hazard ratios, are not enough to assess the real predictive value of a biomarker with regard to the complete set of risk factors for atherosclerosis.…”

Estrutura fatorial da versão brasileira da escala razões para fumar modificada

“…[14][15][16][17] The version of the MRSS selected for use has undergone translation and cross-cultural adaptation for Brazilian Portuguese, according to the traditional methodology, as previously described (Annex). 13,18,19 The original scale in English was obtained from Dr. Irvin Berlin, at Centre Hospitalier-Universitaire Pitié-Salpêtrière, Paris. This instrument was first translated to Portuguese by three Brazilian physicians who had lived in English-speaking countries for long periods.…”

“…12 The MRSS has been recently translated and transculturally adapted to Brazilian Portuguese, from an English language version obtained from the original authors. 13 This study aims to investigate the factorial structure and psychometric properties of this Brazilian version of the scale, which have not yet been described.…”

“…13 Volunteers for this study were selected among individuals who spontaneously came to donate blood in a reference center for hemotherapy in the state of São Paulo. This strategy allowed us to investigate the motivational profile for smoking cigarettes in a context closer to the community's epidemiological reality.…”
