Secondary Outcome Measures
To measure compliance, we asked the following question with regard to each of the 6 training modules at T1: “have you worked through the module?” The participants answered on a 5-point scale (1=no; 5=yes, completely). We also asked, “on how many days during the week after you learned about the daily exercise did you practice it?” The participants could indicate “none” and up to “more than five days.” In addition, trainers filled in an attendance list to document how often the blended training participants joined group sessions.
