“…Despite not being an officially recognized mental health disorder, previous research has demonstrated that PSMU can longitudinally influence a wide range of psychiatric outcomes and behaviors, including, but not limited to, increased severity of insomnia, stress, depression, and anxiety (Brailovskaia and Margraf, 2017;Brailovskaia et al, 2019a), in addition to suicide-related outcomes (Brailovskaia et al, 2020). At the cross-sectional level, PSMU has been linked to decreased sleep quality and life satisfaction (Sha et al, 2019;Buda et al, 2020;Duradoni et al, 2020), emotional maladjustment (Hawes et al, 2020), lower productivity (Rozgonjuk et al, 2020d), narcissistic traits (Brailovskaia et al, 2020), poorer psychological functioning (Sampasa-Kanyinga and Lewis, 2015), phubbing (Karadag et al, 2015), binge drinking (Spilkov et al, 2017), and addictive usage (Andreassen and Pallesen, 2014;Ryan et al, 2014;Andreassen, 2015;Pontes et al, 2018).…”
