“…As prescribed by the literature, the trust dimension aggregates attributes related to the leadership’s ability to easily dialogue, give support for the accomplishments of activities, show concern for the team’s welfare in the work environment, allow participation in hospital decision-making and respect individual rights (Bowie, 2000; Park and Kim, 2009; Tuan, 2015; Freire and Azevedo, 2015; Udod et al (2017). Trust in hospital leaders had already been deemed important to nursing professionals in previous studies carried out by Sellgren et al (2007), Hayes et al (2010), Huang et al (2010), Siqueira and Kurcgant (2012), Jefferson et al (2014), Freire and Azevedo (2015), Chiarini and Baccarani (2016), Robson and Robson (2016), Udod et al (2017), among others. On the other hand, the attributes related to role clarity, which was believed to be part of the trust dimension as stated in the literature (Cortese et al , 2010; Lu et al , 2012, Mun et al , 2015), constituted a distinct dimension designated role clarity containing items related to the absence of ambiguity as far as what management expects from the work performed by nursing professionals.…”
