Smoking cessation

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.
