Abstract
INTRODUCTION: Many postsecondary students use social media at an age when mental health issues often arise for the first time. On social media, students describe their mental states or social interactions using psychiatric language. This is a process of mental health labelling as opposed to receiving a formal diagnosis from a psychiatrist. Despite substantial literature on psychiatric labelling effects such as stigma, little research has addressed the mechanisms and effects of labelling through social media. Our objective is to summarise the existing evidence to address this gap. METHODS AND ANALYSIS: This review includes articles in English published since 1995 on how postsecondary students interact with mental health labels in their use of social media. We will consider empirical studies and theses. The search strategy includes SCOPUS, PubMed, OVID MEDLINE (to access APA PsycINFO), Web of Science and ProQuest Global Dissertations and Theses. This scoping review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extensions for protocols and Scoping Reviews guidelines. The artificial intelligence application, Connected Papers, will assist in identifying additional references. The outcomes of interest are labelling by self or others and changes in self-concept and presentation associated with these labels. Two researchers will independently identify the included studies and extract data, solving disagreements with a third opinion. We will produce tables and narrative descriptions of the operationalisation and measurement methods of labelling and social media use, reported effects and uses of labelling, and explanatory mechanisms for the adoption of labels. ETHICS AND DISSEMINATION: This literature review does not require ethics approval. The researchers will present their findings for publication in an open-access peer-reviewed journal and at student/scientific conferences. Potential knowledge users include university students, social media users, researchers, mental health professionals and on-campus mental health services.
