| Intervention | The online self-help smoking cessation program consists of three components: 1. Smoking cessation module containing exercises which are based on cognitive behavioural therapy 2. Discussion forum 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. |
