Design outcomes

Primary

MeasureTime frame
Participation rate, defined as the percentage of patients who actually participated in the social networks study. That is the total number of patients who had completed an interview or questionnaire for the social networks study divided by the total number of participants in the program evaluation.

Secondary

MeasureTime frame
1. Conditional participation rate: Defined as the total number of patients who had completed an interview or questionnaire for the social networks study divided by the total number of patients willing to participate in the study. 2. Willingness to participate: Defined as the percentage of patients initially willing to participate in the social network study. That is the total number of patients willing to participate divided by the number of participants in the program evaluation. The response trials are embedded within a program evaluation which has been designed as a two-arm randomized controlled trial. For this program evaluation, questionnaires containing invitations for the response trials were send at baseline of the program. Willingness to participate and preference for participation mode, were measured up to 2 months after sending questionnaires with invitations. We planned to perform interviews and send questionnaires on behalf of the social networks study within two months after receipt of completed invitations.
