"Professor Pascual-Ferrá provides a real service to researchers by assembling not only the story of research into trust but also the key scales with which people examined trust. Taking even a brief look at the tables accompanying this study of trust, one easily sees how unsettled this research area remains. Trust as a concept appears in every area of communication research—media studies, interpersonal studies, group communication studies, organizational communication studies, strategic communication studies, new media studies, and so on. Surprisingly, only a few researchers seem to build on existing scales of trust." (Editor's Introduction, page 3)
