Personal Health Records (PHR) systems provide individuals with access and control over their health information and consequently can support individuals in becoming active participants, rather than passive recipients, in their own care process. In spite of numerous benefits suggested for consumers' utilizing PHR systems, research has shown that such systems are not yet widely adopted or well known to consumers. Bearing in mind the potential benefits of PHRs to consumers and their potential interest in these systems-and that similar to any other type of information system, adoption is a prerequisite for realizing the potential benefits of PHR systems-research is needed to understand how to enhance the adoption rates for PHR systems.
This research seeks to understand how individuals' intentions to adopt PHR systems are affected by their self-determination in managing their own health-the extent of their ability to take an active role in managing their own health. As such, this research aims to develop and empirically validate a theoretical model that explains PHR systems adoption by the general public through the integration of theories from the information systems and psychology literatures.
This research employs a cross-sectional survey method targeted at the Canadian general public without any prior experience in using PHR systems. A partial least squares approach to structural equation modeling was used to validate the proposed research model of this study (N=159).
Individuals with higher levels of ability to manage their own health (self-determination) are more likely to adopt PHR systems since they have more positive perceptions regarding the use of such systems. Further, such self-determination is fueled by autonomy support from consumers' physicians as well as the consumers' personality trait of autonomy orientation.
This study advances our theoretical understanding of PHR systems adoption. It also contributes to practice by providing insightful implications for designing, promoting, and facilitating the use of PHR systems among consumers.
个人健康记录（PHR）系统使个人能够访问和控制自己的健康信息，从而可以支持个人在自身护理过程中成为积极参与者，而非被动接受者。尽管研究表明使用PHR系统对消费者有诸多益处，但此类系统尚未被广泛采用，消费者对此也并不熟知。鉴于PHR对消费者的潜在益处以及他们对这些系统的潜在兴趣，并且与任何其他类型的信息系统一样，采用是实现PHR系统潜在益处的先决条件，因此需要开展研究以了解如何提高PHR系统的采用率。
本研究旨在了解个人采用PHR系统的意愿如何受到其自我管理健康的自主程度（即在管理自身健康方面积极发挥作用的能力程度）的影响。因此，本研究旨在开发并通过实证验证一个理论模型，该模型通过整合信息系统和心理学文献中的理论来解释公众对PHR系统的采用情况。
本研究采用横断面调查方法，目标人群为加拿大普通公众，他们之前没有使用PHR系统的经验。采用偏最小二乘法结构方程建模来验证本研究提出的模型（N = 159）。
自我管理健康能力（自主程度）较高的个人更有可能采用PHR系统，因为他们对使用此类系统有更积极的看法。此外，消费者医生提供的自主支持以及消费者的自主取向人格特质会增强这种自主程度。
本研究推进了我们对PHR系统采用情况的理论理解。它还通过为设计、推广和促进消费者使用PHR系统提供有见地的启示，为实践做出了贡献。
