“…This said, studies with mainly non-clinical samples have repeatedly demonstrated that PSU and problematic social networks use are associated with symptoms of depression and anxiety (Elhai, Dvorak, Levine, & Hall, 2017;Elhai, Levine, & Hall, 2019;Primack et al, 2017), as well as other important factors, such as poorer academic achievement (Kates, Wu, & Coryn, 2018;Rozgonjuk, Saal, & T€ aht, 2018), decreased productivity (Duke & Montag, 2017), and riskier driving (Oviedo-Trespalacios, Haque, King, & Demmel, 2018a;Oviedo-Trespalacios, Haque, King, & Washington, 2018b). In addition, PSU has been associated with transdiagnostic constructs relevant to development and maintenance of anxiety and mood disorders, such as emotion dysregulation (Hoffner & Lee, 2015;Pancani, Preti, & Riva, 2019;, intolerance of uncertainty Rozgonjuk et al, 2019b, excessive reassurance seeking (Billieux, Maurage, Lopez-Fernandez, Kuss, & Griffiths, 2015aElhai et al, 2020), personality traits, such as neuroticism (Balta, Emirtekin, Kircaburun, & Griffiths, 2018;Cho, Kim, & Park, 2017;Lachmann, Duke, Sariyska, & Montag, 2019) and impulsivity (Billieux, Van der Linden, d'Acremont, Ceschi, & Zermatten, 2007;Kim et al, 2016;Peterka-Bonetta et al, 2019), and fear of missing out (Gezgin, 2018;Servidio, 2019;Wolniewicz, Rozgonjuk, & Elhai, 2019). Similarly to PSU, studies have found problematic social networks use to be associated both with psychopathology (Shensa et al, 2017), transdiagnostic factors, such as fear of missing out and neuroticism (Blackwell et al, 2017), and decreased work productivity (Zivnuska, Carlson, Carlson, Harris, & Harris, 2019;Rozgonjuk, Sindermann, Elhai & Montag 2020).…”
