| Scientific title | The effects of an interactive web-based intervention to promote healthy behaviour: a randomised single-blind study with a waiting list control condition |
| Study objectives | Respondents who receive access to the interactive web-based intervention will show more improvement in healthy behaviour (nutrition and exercise) than respondents in the waiting-list condition after the intervention period of 12 weeks. |
| Ethics approval(s) | No ethics approval needed in the Netherlands for this trial on online prevention. |
| Health condition(s) or problem(s) studied | Healthy nutrition and exercise habits |
| Intervention | Intervention: Access to interactive web-based application: participants can create a personal account at the intervention website and can use the application as often as they like to for the intervention period of 12 weeks. Control: Waiting-list: participants receive a newsletter (once every 3 weeks) with general information (no information on healthy behaviour). After the intervention period of 12 weeks, they receive access to the application. |
