Background:The content produced by individuals on various social media platforms has been successfully used to identify mental illness, including depression. However, most of the previous work in this area has focused on user-generated content, i.e., content created by the individual, such as an individual's posts and pictures. In this study, we explored the predictive capability of community-generated content, i.e., the data that are generated by a community of friends or followers, rather than by a sole individual, to identify depression among social media users.
