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. [ABSTRACT FROM AUTHOR]
