: Since an online survey concerning nurses’ careers does not constitute biomedical research (Switzerland’s Law on Research on Human Beings (L 810.30, art. 118)), this sub-study required no approval by the Swiss Ethics Commission. However, the nurses at work study requested and obtained a favourable presidential opinion from the Swiss Ethics Committee on research involving humans (Protocol 119/14 of April 16, 2014).
