The passion concept had received little attention in Psychology given that those who studied it placed an emphasis on its motivational aspects. For example, according to Frijda, Mesquita, Sonnemans and Van Goozen (1991), passions are defined as priority objectives with emotionally important results. What’s more, the passion concept has also been placed in different contexts such as creativity (Goldberg, 1986) and the passion for driving vehicles (Marsh & Collet, 1987). These works had not resulted in a great deal of empirical research and consequently Vallerand et al. (2003) found that almost all the empirical work on passion had been carried out in the field of personal relationships.
