- InterventionsBased on positive early experiences, the smoking cessation (SC) intervention in this study will be based on CBT, motivational interviewing, self-control principles as described in the ‘Handbook for CBT for substance abuse and gambling’ and acceptance and commitment therapy (ACT). The intervention will be a 100% self-help multi-session internet-based smoking cessation program. The intervention will also provide additional human support in the shape of a moderated peer-to-peer discussion forum.

The control-condition intervention will provide plain information on risks of smoking in general and especially for cancer survivors. The control interventions will also provide tips on how to quit smoking. All information will be based on existing prevention brochures developed or maintained by the Trimbos institute, which will be tailored to cancer survivors. Participants can visit the control intervention pages as often as they want during the study period. However the information on these pages is static, will not change over time, and is not tailored to the individual participant.
- Primary outcomePrimary outcome variables are the Timeline FollowBack (TLFB) scores on tobacco use in the past 7 days (tobacco RCT) at 6 months post-randomisation. Main study parameter is tobacco abstinence post-randomisation and will be measured at all measurement waves.
- Secondary outcomeSecondary outcome measures include: Quality of life, treatment satisfaction, nicotine dependence, and an additional question about tobacco use in the 14 days prior to 4 weeks after the set quit date, to comply with the Russel Standard and thus make the study better comparable to international smoking cessation studies.
- TimepointsMeasurement waves will take place at baseline and 3, 6, and 12 months post-randomisation.

- PublicationsWe intend to publish in international peer-reviewed journals
- Brief summaryBecause of developments in early detection and treatment, many adult cancer survivors can expect to live for many years after treatment. However, cancer survivors are at an increased risk for recurrence and secondary cancers. As smoking and alcohol (mis)use are among the main risk factors for developing cancers, reducing tobacco and alcohol misuse contributes considerably to the prevention of second cancers among cancer survivors, as well as to improving their quality of life.

Therefore we intend to test the effectiveness of an optimized smoking cessation internet intervention in a sample of cigarette smoking cancer survivors, in comparison to a control condition (internet-based information brochure on smoking).
