Abstract: Mobile health (mHealth), is renowned as a new healthcare paradigm providing ubiquitous and pervasive health information and services through mobile communication devices. In an endeavour to expand the technology adoption research domains, this thesis presents three studies to investigate individuals' different use intentions of mHealth services. Study I is designed to explore the relationships among health promotion expectancy, disease prevention expectancy, regulatory focus, and routine use intention of mobile health services based on expectancy and regulatory focus theories. In view of the increasing importance of mobile technologies applied in the healthcare industry to promote healthy behaviours and prevent illnesses, examining the factors that influence individuals' routine use of those emerging technologies is imperative. Findings reveal that health promotion expectancy has a stronger effect on individuals' routine use intention than disease prevention expectancy. In addition, promotion focus exerts a moderating effect on the relationship between health promotion expectancy and routine use intention. Study II theorizes two information systems (IS) use behaviors associated with individuals' usage intention of mobile health services. Emergency use refers to individuals' use of IS in emergency situations. Routine use refers to individuals' use of IS on a daily basis. We adopt motivation theory as our overarching theoretical lens to investigate the influence of individuals' different motivation incentives on individuals' emergency and routine use intentions of mHealth services. We also investigate the influences of technological and psychological antecedents on extrinsic and intrinsic motivations. Based on data collected from 241 participants, we find that perceived usefulness enhances people's emergency and routine use intentions of mHealth services, and perceived enjoyment positively influences routine use intention. In addition, we find that perceived source credibility, perceived service availability, and perceived diagnosticity influence perceived usefulness (extrinsic motivation); whereas, perceived autonomy, perceived competence, perceived relatedness, and curiosity affect perceived enjoyment (intrinsic motivation). This research offers insights for IS literature on understanding mHealth emergency and routine use behaviors. Moreover, the increasing number of studies have been conducted to investigate individuals' adoption behaviour of mHealth service, but how service characteristics influence people's use intention has not been drawn much attentions. In addition, individuals with different personal traits can also affect their behavioural decisions. Therefore, using data collected from 350 participants, Study III aims to investigate the effects of perceived service relevance and perceived information accuracy on individuals' use intention of mHealth services. Moreover, individuals' innovativeness and privacy concern are also introduced as two moderators influencing the relationships between services characteristics and use intentions of mHealth services. This study provides a new insights of perspective influencing individuals' usage behavior of mHealth services that can shed light on the further understanding of how individuals' adopt new information service or technologies, which contribute both information system and health care research area in a very promising way.
