Evidências de Validade da Versão Brasileira da Escala de Dimensões da Dependência do Tabaco (EDDT)

Abstract

Validity evidence for the Brazilian version of the Tobacco Dependence Dimension Scale (TDDS) The aim was to adapt the Tobacco Dependence Dimension Scale (TDDS) for the Brazilian context and to gather evidence of construct and criterion validity. A total of 270 active smokers from different states participated, the majority being female (51.7%, ƒ=139), ranging in age from 18 to 68 years (M=33.77, SD=12.54) and smoking time ranging from 1 to 53 years (M=15.01, SD=12.50). First, back translation and content validation procedures were performed. Next, the participants responded to the Tobacco Dependence Dimension Scale (TDDS) and a sociodemographic questionnaire. Exploratory factor analysis indicated a structure composed of 26 items divided between four factors. Evidence of criterion validity was also found for all the TDDS factors as a function of intent to join a tobacco dependence program. According to this initial study, the TDDS presents evidence of psychometric adequacy to assess tobacco dependence.
