Abstract: | This study applies the dualistic model of passion (Vallerand et al., 2003) to the work setting and examines the relationships between harmonious passion (characterized by a strong but controllable desire to engage in an activity), obsessive passion (characterized by an internal pressure to carry out an activity), and optimal functioning outcomes at work. Harmonious passion associated positively with: mental health; three elements of flow (i.e., concentration, control, and autotelic experience); vitality, and affective commitment. These relationships were partly mediated by satisfaction of the basic psychological needs of autonomy, competence, and relatedness. In contrast, obsessive passion directly and negatively predicted mental health and weakly but positively predicted autotelic experience. Theoretical and applied implications are discussed.
