Study Aims

• Determine changes in smokers' and non-smokers' attitudinal and behavioural responses to smoke-free legislation in Scotland.

Study Design

• Quasi-experimental cohort study of adult smokers and non-smokers in Scotland and the rest of the UK, in which respondents from the rest of the UK were used as controls.
• A probability sample of smokers was recruited pre-legislation in February-March 2006 to participate in a telephone survey. The cohort was followed up one year later in February-March 2007. The survey was based on the International Tobacco Control Policy Evaluation (ITC) Project.
• Outcome measures included: observed smoking behaviour in private and public places; self-reported smoking behaviour and quit attempts in smokers; attitudes towards and compliance with legislation; social norms about smoking.

Research Instruments & Protocols

• Phase 1: Baseline survey (Feb-Mar 2006)
• Phase 2: Follow-up survey (Feb-Mar 2007)

Main Outcomes

• There was a much larger reduction at follow-up in observed smoking in public places (pubs, restaurants, and workplaces) for the Scottish sample compared with the sample for the rest of the UK.
• Support for the smoke-free legislation increased more over the study period among the Scottish sample than in the sample for the rest of the UK.
• However, no differences in smoking cessation indicators were observed between countries.
• Self-reported frequency of visits to pubs and restaurants were comparable in Scotland and the rest of the UK. However, post-legislation, non-smokers in Scotland were more likely to frequent pubs more often then non-smokers from the rest of the UK.
• The change in the proportion of smokers reporting a smoke-free home, and number of cigarettes smoked inside the home in the evening, was comparable in Scotland and the rest of the UK.
• There was no evidence of displacement of smoking from pubs to the home.
