Research On The Effects Of Personal Characteristics On Mobile Health Services' Adoption Intentions

Mobile health(mHealth),is renowned as a new healthcare paradigm providing ubiquitous and pervasive health information and services through mobile communication devices.In the domestic market,the actural adoption rate is still very low.Although extant literature regarding to mHeal th services has been drawn increasing attentions,the relevant research is relatively scattered,lacking of an integrated and systematic framework.In addition,exploring the influencing factors of mHealth adoption behavior requires more comprehensive research model.Therefore,drawing upon Technology Acceptance Model,Regulatory Focus Theory,and Motivation Theory,in an endeavor to expand the technology adoption research domains,this thesis presents three studies to investigate individuals' different adoption intentions and influencing factors of mHealth services based on the personal characteristics perspectives.Study?theorizes two information systems(IS)use behaviors associated with individuals' behavioral intention of mobile health(mHealth)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 th e influences of technological and psychological antecedents on extrinsic and intrinsic motivations.Based on data collected,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.In addition,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.Study ? is designed to explore the relationships among health promotion expectancy,disease prevention expectancy,regulatory focus,and routine use intention of mobile health(mHealth)services based on expectancy and regulatory focus theories.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.Moreover,the increasing number of studies have been conducted to investigate individuals' adoption behavior of mHealth service,but how service characteristics influence people's use intention has not been drawn much attentions.Study? aims to provide 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 a rea in a very promising way.
