To promote the adoption of PHR system, understanding the factors that affect patients’ adoption of PHR system is of necessity. Based on previous research, this paper tries to develop a model to explore those elements that influence the behavior intentions of patients from the perspective of consumers. It is assumed that individual features and environmental features affect individuals’ attitudes to PHR. Data from 265 participants’ response to questionnaire was collected. The SPSS and partial least squares (PLS) technique was adopted to examine the casual relationships this paper hypothesized. The results show that affordability and coercive pressure have the significant effect on individuals’ attitude towards PHR. Therefore, suggestion regarding what developers, institutions and government should do to improve the adoption rate of PHR was raised.
