Baseline questionnaires assessed demographics, smoking history, and nicotine dependence. The demographics questionnaire tapped characteristics such as gender, race (smokers were asked which race they most strongly identified with), Hispanic ethnicity (i.e., reporting at least one parent of Hispanic origin), income, education level and age. A smoking history questionnaire provided information about smoking behavior, smoking restrictions at home and work, self-efficacy to quit smoking, spouse smoking patterns, and motivation to quit smoking. Nicotine dependence questionnaires included the Fagerstrom Test of Nicotine Dependence (FTND) 19, the Nicotine Dependence Syndrome Scale (NDSS) 20, the Tobacco Dependence Screener (TDS) 21, and the Wisconsin Inventory of Smoking Dependence Motives (WISDM) 22.
