Step	Where	Description
1: Computer tailored feedback	In the waiting room of general practice on a tablet	When patients come into practice they are informed by their GP or by the practice assistant about the eHealth programme. When patients want to use the programme, they receive the tablet on which they can fill in a questionnaire. Based on their answers, tailored feedback on patients’ health behaviour is automatically generated by the programme.
	OR
	During consultation on a tablet
2: Making an action plan	In general practice (when enough time)	Based on the feedback, patients can decide if they want to make an action plan. They can make this action plan in the programme on the tablet by reading tips and answering questions. Patients make an action plan by anticipating on difficult situations and by selecting goals and strategies.
	OR	Patients can also choose to make this action plan back at home by using the programme on a website on their own computer.
	At home (when not enough time)
3: Feedback by GPs	In general practice	When patients received their personal feedback/made their action plan, they can discuss this with their GP during consultation.
	OR	After the action plan is made, patients can also choose to email the plan to their GP.
	At home
4: Follow-up	In general practice	When patients come back to practice, they can discuss with their GP if they have reached their goals.
	OR	Patients are prompted by email and can evaluate their health goals online by filling in a questionnaire to evaluate if they have reached their health goals.
	At home
