The scientific community has shown an increasing interest in exploring the practices and routines of journalists in different contexts (Hanitzsch et al., 2011). The trust journalists place in public institutions is a key variable to understand their professional culture (Hanitzsch & Berganza, 2012; Brants, de Vreese, Möller & van Praag, 2010; van Dalen, Albæk & de Vreese, 2011), as well as citizens' interest and trust in politics (Cappella & Jamieson, 1997). The goal of this paper is to identify the level of trust of Spanish journalists in public institutions and to verify whether media type, regional scope and ownership influence these trust levels. As part of the 'Worlds of Journalism Study', an international research project, we surveyed a probabilistic sample (n=390) of Spanish journalists, stratified by media type and region, from March 2014 to May 2015. In comparison to the results of the last survey carried out by Hanitzsch & Berganza (2014), the findings of this study show a significant decrease in trust levels (specially towards politicians), probably as a consequence of the economic crisis. The analysis also revealed partial differences in journalists' trust levels according to media type (TV, radio, printed press, online press, etc.), but showed homogeneous trust levels among journalists working for media with different geographical reach (regional, national) and ownership (public, private, etc.). It is necessary to further develop this line of research with explanatory models that allow delving into the origins of the distrust of Spanish journalists.
