“…Over the past two decades, research examining work addiction has greatly increased (Clark, Michel, Zhdanova, Pui, & Baltes, 2016), both in terms of conceptual clarification and further consistent recognition regarding the correlates of work addiction (Andreassen, 2014;Atroszko, 2012;Griffiths, 2011;Shimazu, Schaufeli, Kamiyama, & Kawakami, 2015). Furthermore, many scholars have examined the differentiation between work addiction and work engagement as well as harmonious and obsessive passion towards work, both theoretically and empirically (e.g., Andreassen, 2014;Burke & Fiksenbaum, 2009;Birkeland & Buch, 2015;Karanika-Murray, Duncan, Pontes, & Griffiths, 2015;Karanika-Murray, Pontes, Griffiths, & Biron, 2015;Quinones & Griffiths, 2015;Quinones, Griffiths, & Kakabadse, 2016;Vallerand, Paquet, Philippe, & Charest, 2010;van Beek, Hu, Schaufeli, Taris, & Schreurs, 2012;van Beek, Taris, Schaufeli, & Brenninkmeijer, 2014). Studies have also demonstrated that the concepts are either slightly positively related (Shimazu & Schaufeli, 2009) or not at all (van Beek, Taris, & Schaufeli, 2011).…”
