Drawing on Self-Determination Theory (SDT; Deci et al., 2017), this study examines the associations between authenticity at work, motivation and well-being, assuming that motivation would at least partly mediate the association between authenticty and well-being. Since authentic behavior refers to the degree to which a person acts in agreement with their true self (i.e., one's own core values), high levels of authenticity at work should relate positively to more intrinsic types of motivation regulation and negatively to more extrinsic types of motivation regulation. Moreover, high levels of authenticity should be associated with higher well-being at work (i.e., higher work engagement and lower burnout). Structural equation modeling using cross-sectional data from 546 participants revealed that self-determined motivation (i.e., autonomous motivation) showed positive associations with authenticity at work and that non-selfdetermined motivation (i.e., controlled motivation and amotivation) showed negative associations with authenticity at work. The positive associations increased in strength with increasing self-determined motivation. A similar-but reversed-pattern was found for the negative associations. Parallel mediation analysis revealed that self-determined motivation partially mediated the relationship between authenticity and well-being at work.Keywords: Authenticity, burnout, SDT, work motivation, work engagement
INTRODUCTIONThe associations among authenticity, self-determined motivation and well-being at work have gained considerable interest over the past few years. One line of research has successfully related authenticity-i.e., the degree to which someone acts in agreement with their true self (van den Bosch and Taris, 2014a)-to various aspects of well-being. For example, Toor and Ofori (2009) found a positive association between experienced authenticity and leaders' well-being. Kernis and Goldman (2006) reported positive associations between self-reported authenticity on the one hand and eudaimonic well-being, hedonic well-being, and life satisfaction on the other. Finally, Emmerich and Rigotti (2017) examined the associations among authenticity on the one hand and depression, work ability and intrinsic motivation on the other.In a different line of research, a series of studies focused on the associations between well-being on the one hand and various types of motivation on the other. In this research a major distinction is made between self-determined vs. non-self-determined motivation and behavior (Deci et al., 2017), arguing that-since they stem from the self-especially self-determined behaviors are "authentic" and should therefore be associated with positive well-being . For example, van Beek et al. (2012) showed that self-determined forms of motivation were associated with Van den Bosch and Taris Authenticity at Work, Motivation, and Well-being favorable scores on burnout and work engagement. Similarly, Van den Broeck et al. (2011) found that autonomous motivation was associated with favorable...
