Engagement for teaching was measured by the Utrecht Work Engagement Scale (UWES; Schaufeli & Bakker, 2004). The scale includes items measuring three correlated dimensions of work engagement: vigor, dedication, and absorption. Vigor is characterized by high levels of energy and mental strength whereas dedication refers to experiencing enthusiasm, inspiration, pride, and challenge. Absorption refers to being concentrated and involved in one's own work. We used the short 9-item version of the scale (Schaufeli & Bakker, 2010). In our study the scale displayed a Cronbachs’ alpha of .90.
