Most existing smoking cessation services are based on '5A's' and '5R's' models which are recognized by the World Health Organization as a standardized tool for smoking cessation. While there are more techniques that are known to be effective and could be incorporated in existing smoking cessation interventions to further promote their effectiveness. This study is to examine the effectiveness SDTM in assisting adult smokers in Hong Kong to quit.
A randomized controlled trial (RCT) will be conducted. One-hundred adult smokers aged 25 or above will be recruited from smoking hotspots in Hong Kong. Participants in the intervention group will be contacted by our trained research assistant to receive a telephone counselling session at baseline. Participants can choose to receive their own smoking cessation treatment options from our menu. Control group participants will only receive a self-help quitting leaflet

Self-reported abstinence at 6-month follow-up
participants will be asked about their self-reported abstinence in the past 7 and 30 days
Time frame: At 6-month follow-up
Biochemically validated abstinence
validate the self-reported abstinence if the level of carbon monoxide in expired air was less than 4 parts per million and saliva cotinine level was less than100 ng/mL in parallel tests
