Intervention(s)
|
The online self-help smoking cessation program consists of three components;
1. A smoking cessation module containing exercises which are based on cognitive behavioural therapy;
2. A discussion forum, and
3. State-of-the art information and tips about smoking cessation.
The control group gets access to an online smoking cessation brochure (?Quit smoking; why and how?) which advises on smoking cessation and gives information about withdrawal symptoms. Each intervention can be used in accordance with their needs.
Both interventions are developed by STIVORO.
