Abstract
INTRODUCTION: Social media, gaming, and other types of screen time have been associated with a number of child and adolescent mental health concerns, including NSSI, suicidal ideation, suicide attempts and suicides. However, findings have been complicated by a quickly changing technological landscape and the COVID-19 pandemic. Inconsistent findings may be related to the dissimilar impacts of different screen time types on different age groups. The aim of this systematic review is to explore the pattern of impact of different screen time types on children and adolescents, investigating age groups of particular risk, and synthesising outcomes, recommendations, and strategies described to inform future studies and guidelines. METHODS AND ANALYSIS: A systematic review will be conducted of all study types, and reported using the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. The following databases will be searched for relevant publications: CINAHL, PubMed, Embase, PsycINFO, PsychArticles, Scopus, and Web of Science. Searches will be limited by language (English). Article selection, quality evaluation, and data extraction will be conducted independently by two reviewers. Quality assessment will be conducted using Joanna Briggs Institute (JBI) checklists for the appropriate study type. ETHICS AND DISSEMINATION: Ethics approval is not required since we are not using patient data. Findings will be published in a peer-reviewed journal article, and disseminated via conference presentations. PROSPERO REGISTRATION NUMBER: CRD42023493058.
