Brief Summary
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.
