SMC is a complex phenomenon and encompasses multiple functionalities and platforms, but for the objective of this study, we focused on the frequency of using SMC for two distinctive purposes: formal and informal matters regardless of the platform used (e.g., enterprise social media or public social media). We measured the frequency of formal SMC at work with the following question: “How often do you use social media to keep in touch with your colleagues or work community regarding work-related matters (e.g., on information sharing or agreeing timetables)?” In addition, we measured the frequency of informal SMC at work with the following question: “How often do you use social media to keep in touch with your colleagues or work community regarding nonwork-related matters?” The answer options for both measures were I don't use it, less than weekly, weekly, daily, and many times a day, with answers given numerical values of 0–4, respectively. These measures have been previously used and validated in two Finnish cross-sectional samples (Oksa et al., 2020).
