Opponent Associate Professor, Dr. Atreyi Kankanhalli (School of Computing, National University of Singapore) and custos Professor Mikko Siponen (University of Jyväskylä). The doctoral dissertation is held in English.

IT users’ psychological states and behaviors are major topics especially for Web service companies and organizations, whose working media are IT artifacts (i.e., computer, smartphones, mobile pad etc.).  This is because from the feeling and their activities with IT artifacts influence IT users’ subsequent behaviors on the Web contexts (e.g., knowledge contribution in online communities and participation in SNS etc.) and their outcomes in their life (e.g., perception: usefulness of online communities etc.) and workplace (e.g., their attention capacity during working hours).  Especially, in the case of enthusiastic IT users, who always be with and depend on IT artifacts, their life and outcomes in workplace are highly affected by their IT use behavior and feeling with their IT use.  Therefore, it is crucial to understand the underlying mechanisms that are embedded in IT use.  Thus, we tried to understand the underlying mechanisms in several contexts of IT use in considering each context’s unique features.

This dissertation consists of four essays.  The first essay examines how people react to social networking services (SNS).  In this essay, we attempted to extend the existing model, which includes dedication- and constraint-based mechanisms, by additionally including the obligation-based mechanism underlying SNS-related behavior.  As a result, we found the evidence of the obligation-based mechanism through the effect of social support on normative commitment as well as the effect of normative commitment on moderating comments on SNS.  

The second essay is designed to investigate individuals’ smartphone use.  In particular, we focused on the role of smartphone addiction in shaping individuals’ perceptions about their smartphone.  Our findings suggest that addiction and its negative consequences have different effects on subsequent perceptions such as perceived usefulness and perceived enjoyment of smartphone use.  The third essay is about online community behavior.  Drawing on the model of engagement, we developed a conceptual model by introducing a relatively new notion of prominence, which reflects how accessible and easy it is to retrieve thoughts and feelings about an object.  We found that both prominence and engagement have significant effects on separation distress that, in turn, is directly related to continuance intention but lacks a direct link with knowledge contribution in online communities.  Finally, the fourth essay developed and tested a theoretical framework on Non-Work-Related Computing.  Drawing on the concept of recovery, we investigated the antecedents and performance-related consequences of recovery factor.  Our findings indicate that three aspects of NWRC (psychological detachment, relaxation, and a sense of mastery) influence recovery, which in turn determine employees’ performance-related outcomes (attentional capacity and personal initiative).

In total, this dissertation assessed the IT users’ psychological states and behavior of over 2496 IT users in several IT use contexts.  Our empirical results support our conceptual models, providing theoretical insights and strategic insights in practice.
