Specifically, harmonious passion is positively related, whereas obsessive passion is either unrelated or negatively related, to psychological adjustment indices (e.g., Donahue et al, 2012;Fernet, Lavigne, Vallerand, & Austin, 2014;Houlfort, Philippe, Vallerand, & Ménard, 2014;Houlfort, Vallerand, Laframboise, Fernet, & Koestner, 2015;Lafrenière, St-Louis, Vallerand, & Donahue, 2012;Lafrenière, Vallerand, & Sedikides, 2013;Philippe, Vallerand, & Lavigne, 2009;Rousseau & Vallerand, 2008;Vallerand, 2012;Vallerand et al, 2007) and positive emotions and flow during activity engagement (e.g., Carpentier, Mageau, & Vallerand, 2012; Lafrenière, Jowett, Vallerand, Donahue, & Lorimer, 2008, Study 2;Vallerand, Rousseau, Grouzet, Dumais, & Grenier, 2006, Study 2).…”
