Ethics approval and consent to participate: The Swiss StudentLife study was reviewed and approved by the Ethics Commission of ETH Zürich in 2016 (approval 2016-N-27). We followed a detailed informed consent protocol, including an information and consent procedure prior to each survey for active study participants. There was a separate informed consent procedure for the API Facebook data collection. Information about Facebook ties was only collected when both connected individuals had given their consent. Further details on data collection and ethics are provided in Vörös et al. [ ].
