Summary
Brief summary
Households are selected at random from the New South Wales Electronic White Pages. Each household is contacted by telephone to establish if there is an adult daily smoker resident. If more then one daily smoker lives in the household one smoker is selected at random. Consenting smokers are randomly allocated to receive either proactive telephone counselling calls or a one-off mail-out of written self-help materials. The assessor (ie, telephone interviewer) is unaware of group assignment as computer software allocates participants to conditions. Participants complete telephone interviews at 4, 7 and 13 months post-recruitment to examine quitting behaviours. It is hypothesised that compared to the written self-help group, significantly more participants in the telephone counselling group will have quit smoking at 4, 7 and 13 months post-recruitment.
