Outcome measures
Primary outcome
7 day-point prevalence abstinence from tobacco six monts post-intervention;
Secondary outcome
intention to quit smoking six months post-intervention
Background summary
Individuals differ substantially in terms of information processing preferences as their need for autonomy. By applying message frame tailoring based on the need for autonomy - in addition to content tailoring - information can be presented in an even more personalised way, taking information processing preferences into account and yielding more positive effects on health behaviour. Therefore the goal of this project is to develop and test an online computer-tailored smoking cessation intervention including both content tailoring and message frame tailoring.
Study objective
Both offering choice and using non-controlling language have an independent positive influence on perceived autonomy-support. Not offering choice and using controlling language have an independent positive influence on reactance. Message frame tailoring is more effective in increasing smoking cessation rates than non-tailored and content tailored only interventions in a field study. In addition, message frame tailoring is more cost-effective than non-tailored and content tailoring only interventions in a field study.
Study design
baseline questionnaire and follow-up questionnaires at one month and six months
Intervention
An existing online computer-tailored smoking cessation intervention will be adapted and used to test the effects of message framing in an online experiment. The output of this experiment will guide the development of a new online computer-tailored smoking cessation intervention with both content and messge frame tailoring, which will be tested for (cost-)effectiveness in a randomized controlled trial.
