    Technology acceptance research has shown that trust is an important factor fostering use of information systems (IS). As a result, numerous IS researchers have studied factors that build trust in IS. However, IS research on trust has mainly focused on user's trust in the IS itself, neglecting other targets of trust that might also drive IS use from a user's point of view. Accordingly, we investigate the importance of different targets of trust in IS use. Therefore, we use the concept of a network of trust and identify four different targets of trust that are prevalent. Afterwards, we develop our research model and evaluate it using a free simulation experiment. The results show that multiple targets of trust are important in the context of IS use. In particular, we highlight the importance of a second target - trust in the provider - which is equally important as trust in the IS itself. Consequently, IS providers should focus not only on fostering users' trust in their IS but also on positioning themselves as trustworthy providers. Additionally, we show that a third target - trust in the Internet - has significant indirect effects on important constructs in the context of IS use.

    Towards a Theory of Explanation and Prediction for the Formation of Trust in IT Artifacts

    In this paper we argue that the predominant trust conceptualization in IS has a major weakness when researching trust in IT artifacts and that a theory of explanation and prediction for the formation of trust in IT artifacts is necessary to face the upcoming challenges. Thus, we motivate a trust conceptualization from the HCI discipline, and develop a formative measurement model for trust in IT artifacts to achieve deeper insights on the formation of trust. The results of our pre-study with 102 undergraduate students suggest that the new conceptualization is valueable for creating the desired insights on the formation of trust in IT artifacts. In an upcoming field experiment with about 250 users we expect to gain more detailed and reliable insights in the formation of trust in IT artifacts allowing us to derive a first theory of explanation and prediction for the formation of trust in IT artifacts.

    IS research has shown the importance of trust in domains such as e-commerce or technology acceptance. Researchers also emphasize the importance of the identification of factors that influence trust. Unfortunately, the currently dominant reflective measurement does not offer these insights, and thus this contribution aims at developing a formative measurement model for trust. To achieve this, we address three research questions: a) How can trust be measured, considering trust and measurement theory? b) What indicators should be included in a formative measurement model for trust? c) What is the value of a formative measurement of trust compared to a reflective one? Our results show that the formative measurement model offers detailed insights on the impact of single factors influencing trust. We show that in our study, ability affects trust over twice as much other factors such as benevolence or trustor's propensity.
