“…Problematic smartphone usage has been defined as compulsive usage that leads to impaired daily functioning in terms of productivity, social relationships, physical health, or emotional well-being (Horwood & Anglim, 2018). Despite the various benefits of smartphones, many studies have obtained correlations between problematic usage and stress (e.g., Cao, Masood, Luqman, & Ali, 2018;Kim, Min, Min, Lee, & Yoo, 2018;Kuang-Tsan & Fu-Yuan, 2017;Samaha & Hawi, 2016;Van Deursen, Bolle, Hegner, & Kommers, 2015). The notion that smartphones can cause users to become stressed, overwhelmed, and exhausted has been termed 'technostress' (Ayyagari, Grover, & Purvis, 2011;Lee, Chang, Lin, & Cheng, 2014;Maier, Laumer, Weinert, & Weitzel, 2015;Tarafdar, 2017), or, in some cases, 'techno-exhaustion' (Cao et al, 2018).…”
