Integrating the TTF Model and the Extended UTAUT Model with Perceived Enjoyment to Explore the use Intention of Health Passbook

Health information technology can improve people’s knowledge and participation in medical decision-making. Enhance the efficiency and quality of healthcare and help reduce medical errors, costs and paperwork. Health passbook is a kind of health information technology. It can provide personal health information, manage personal medical conditions and monitor one’s overall health, which is crucial for the government to achieve sustainable development goals. Therefore, this study develops and tests a theoretical model to predict factors that influence people’s behavioral intentions to use their health passbook. It combines the extended Unified Theory of Acceptance and Use of Technology model, Task Technology Fit model and perceived enjoyment to explore the influencing factors of behavioral intention of using health passbook. In terms of questionnaire survey methods, online questionnaires and on-site face-to-face questionnaires are used to collect data. Structural equation modeling was used to analyze 1441 samples from central Taiwan. Partial least squares regression is used for hypothesis testing of the model. research shows: (1). perceived enjoyment, performance expectancy, and social influence were important antecedent factors for the public’s behavioral intentions to use health passbook; (2) . facilitating conditions have a negative impact on behavioral intentions; (3) . perceived enjoyment and tasktechnology fit were a significant determinant of both performance expectancy and effort expectancy; (4) . task characteristics and technology characteristics were key predictors of the task-technology fit. The research results and findings will help to understand the influence of the public on the intention to use the health passbook and provide relevant suggestions.
