“…Moreover, both of them are related to higher engagement in studying/working, longer time devoted to studying/ working, key personality traits (higher neuroticism and conscientiousness), lower performance levels, impaired general health, decreased quality of life, poor sleep, and higher perceived stress (Atroszko, 2015;Atroszko et al, 2015;Griffiths et al, 2018). Furthermore, study addiction and work addiction show similar prevalence rates, which are typically around 8-10% (Atroszko, 2015;Griffiths et al, 2018); however, some studies suggest higher rates in particular populations. For example, the known prevalence rates based on a polythetic cut-off score of the Bergen Work Addiction Scale (which in the absence of the gold standard can be considered the most theoretically sound and empirically valid available cut-off) suggest 6.6% addicted in Denmark, 8.3% in a nationally representative sample in Norway, and 16.8% in Poland (Andreassen et al, 2014;Atroszko, Pallesen, Griffiths, & Andreassen, 2017;Lichtenstein, Malkenes, Sibbersen, & Hinze, 2019).…”
