Air Quality Feedback to Reduce Second-hand Smoke (SHS) Exposure in the Home

Two-hundred smokers (50 in each country) will be recruited and offered low-cost, simple to operate particle counting instruments to measure and log SHS levels in their home for a period of 30 days. During this time near real-time, personalised feedback will be provided to, and discussed with, the smoker along with target-setting and exploration of suitable methods of behaviour-change. Feedback will be given via text message to mobile phones, emails and personal voicecalls. A final visit will gather data on changes made while a proportion of participants (10-20%) in each country will take part in a further qualitative interview by phone to gather data on their experience of the intervention.
