“…Such leaders should inspire trust, respect, and pride so as to increase optimism, hope, and resilience in order to develop to a greater extent than expected (Quick, Macik-Frey, Mack, Keller, Gray, & Cooper, 2006). In a number of different studies transformational leaders have been shown to have a positive impact on: (1) followers' information and learning, as well as on their capacity to go about their daily clinical activities and to improve the quality of service with the patients (Phillips, 2005); (2) individual and collective work engagement through the "contagion of engagement" (Bakker, Le Blanc, & Schaufeli, 2005) from one team member to another, especially when their members collaborate closely to accomplish particular tasks (Salanova, Llorens, Cifre, Martínez, & Schaufeli, 2003); (3) followers' health and well-being (Nielsen, Yarker, Randall, & Munir, 2009); (4) positive affect experience (relaxation, enthusiasm, pleasure, optimism, resilience, and job satisfaction) and work engagement (Llorens, Salanova, & Losilla, 2009), as well as in-and extra-role performance in teams (Cruz et al, in press); (5) self-efficacy, work engagement, and extra-role performance (Salanova, Lorente, Chambel, & Martínez, 2011); and (6) the performance of the group, particularly when leaders transfer their positive emotions (George, 1996).…”
