ESTEVES, Germano Gabriel Lima. Validity evidence for the Brazilian version of the Tobacco Dependence Dimension Scale (TDDS). Aval. psicol. [online]. 2019, vol.18, n.1, pp. 13-20. ISSN 1677-0471.

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.
