The respondents received selleck inhibitor compensation for their participation in each survey by earning points for every answered question, as is standard procedure in the TNS NIPObase web panel.

Measurements Control Variables (2008) Control variables were gender, age group, educational level, heaviness of smoking, smoking status, and attempts to quit smoking in the last year. These variables were assessed at the 2008 survey. Age was categorized as 15�C24, 25�C39, 40�C54, and 55 years and older.

Education was categorized in three levels: low (primary education and lower prevocational secondary education), moderate (middle prevocational secondary education and secondary vocational education), and high (senior general secondary education, pre-university education, and higher professional education). The Heaviness of Smoking Index (HSI) was created as the sum of two categorized measures: number of cigarettes per day and time before smoking the first cigarette of the day (Heatherton, Kozlowski, Frecker, Rickert, & Robinson, 1989). HSI values ranged from 0 to 6 and were positively associated with nicotine dependence. Smoking status was categorized as daily smoker versus occasional smoker. Attempts to quit smoking were categorized as attempted to quit in the last year versus did not attempt to quit in the last year.
