TY - JOUR AU - Kim, Jeongeun AU - Park, hyun - ae PY - 2012 DA - 2012/10/01 TI -基于消费者健康行为意愿的健康信息技术接受模型的开发JO - J Med Internet Res SP - e133 VL - 14 IS - 5 KW -技术接受模型KW -健康行为KW -意愿KW -消费者AB -背景:为了有效地利用健康信息技术促进健康，健康消费者必须具有测量、存储和管理自身健康数据的行为意愿。了解健康消费者的意图和行为是制定和实施有效和高效的战略所必需的。目的:通过描述健康消费者使用HIT的行为意图，建立并验证医疗保健领域的扩展技术接受模型(TAM)。方法:本研究采用横断面描述性相关设计。我们通过添加更多的前因变量和中介变量来扩展TAM模型，以增强模型的解释力，使其更适用于健康消费者的行为意图。额外的前因和中介变量被添加到假设模型中，基于它们的理论相关性，来自健康信念模型和计划行为理论，以及TAM。我们进行了结构方程分析，以检查在理解消费者使用HIT时所涉及的关系的具体性质。研究参与者是来自韩国三个互联网健康门户网站的728名成员。数据通过基于网络的调查收集，使用结构化的自我管理问卷。 Results: The overall fitness indices for the model developed in this study indicated an acceptable fit of the model. All path coefficients were statistically significant. This study showed that perceived threat, perceived usefulness, and perceived ease of use significantly affected health consumers’ attitude and behavioral intention. Health consumers’ health status, health belief and concerns, subjective norm, HIT characteristics, and HIT self-efficacy had a strong indirect impact on attitude and behavioral intention through the mediators of perceived threat, perceived usefulness, and perceived ease of use. Conclusions: An extended TAM in the HIT arena was found to be valid to describe health consumers’ behavioral intention. We categorized the concepts in the extended TAM into 3 domains: health zone, information zone, and technology zone.
