The DEBRA study started in June 2016 and consists of cross-sectional, computer-assisted household interviews in people aged 14 years and older. Every two months a new, representative sample of approximately 2,000 respondents will complete the survey every two months. Per wave, about 500-600 respondents identify themselves as current daily or occasional tobacco smokers or recent ex-smokers (quit attempt during last 12 months). At baseline and six months later, this group will answer detailed questions about their use of tobacco and ANDS, including urges to smoke, motivation to stop, rates, smoking, duration and success of quit attempts, internal and external triggers of quit attempts, use of behavioural and pharmacological cessation aids, and attitudes towards tobacco control policies. Smokers and recent ex-smokers are asked to complete a telephone survey 6 months later.
