“…A subset of outcomes that have previously been indicated to be related to at least one media type (i.e., TV/DVDs, videogames, and chatting/surfing on the Internet) were included in the present study to examine how screen-time trajectories associated with them. These outcomes include mental health and behavioral issues, i.e., depression, anxiety (e.g., Kandola et al, 2021;Stiglic & Viner, 2019), suicidal ideation (e.g., Coyne et al, 2021), self-injury (e.g., Wiguna et al, 2021), aggression (e.g., Keikha et al, 2020), substance use (e.g., Boers et al, 2020), and delinquency (Exelmans et al, 2015). These outcomes were included also as they are common in adolescence and tend to co-occur (e.g., Murray et al, 2022;World Health Organization, 2021).…”
