"In this review of the literature I have attempted to show how researchers in different areas of communication have conceptualized and operationalized trust and trust-related concepts. Trust has been associated most with the concept of credibility, but other words that have been used to operationali ... ze it include believability, accuracy, honesty, truthfulness, trustworthiness, sincerity, competence, expertise, reliability, and goodwill, to name some. The concept of trust, just as credibility, is multi-dimensional, and it seems to depend on the context, the person, and the task that is evaluated, as one may not necessarily trust another with a personal secret but may trust that person to complete a work-related task well. As might have become evident to the reader, our discipline's interest in measuring trust has been mostly utilitarian: trust as a means to an end (e.g., persuasion, credibility, and effectiveness of the communicator, to name some). While not all of the trust-related research in communication has been self-serving, it has focused mostly on the benefits that communicators can derive from growing others' trust in them, and less on the benefit that the act of trusting may have on others beyond the communicator, or other possible outcomes stemming from trust. One of the few exceptions has been in the instructional communication literature, where measures of trust have been used to study levels of student satisfaction, development and learning; interpersonal communication, where measures of trust have been used to study satisfaction in relationships between friends and romantic partners; and health communication, where communicating trust in the patient-provider interaction can increase the patient's self-awareness and sense of well-being. The mostly transactional and utilitarian view of trust that has dominated so far is perhaps a reflection of the increased professionalization of the discipline, the need for practical applications within the business setting and the cultures that sustain them and are in turn sustained by them. It would be interesting for future research to consider trust from the perspective of the person who is doing the trusting what impact does trust have on them beyond being persuaded and returning as consumers of information and products? It would be interesting for future research to approach the study of trust from that perspective as well as from non-traditional (read non-Western/Anglo-Saxon) socioeconomic and cultural perspectives."

"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) more
