With the advent of personal health records and other patient-focused health technologies, there is a growing need to better understand factors that contribute to acceptance and use of such innovations. In this study, we employed the Unified Theory of Acceptance and Use of Technology as the basis for determining what predicts patients' acceptance (measured by behavioral intention) and perceived effective use of a web-based, interactive self-management innovation among home care patients.
Cross-sectional secondary analysis of data from a randomized field study evaluating a technology-assisted home care nursing practice with adults with chronic cardiac disease. MEASUREMENT AND ANALYSIS: A questionnaire was designed based on validated measurement scales from prior research and was completed by 101 participants for measuring the acceptance constructs as part of the parent study protocol. Latent variable modeling with item parceling guided assessment of patients' acceptance.
Perceived usefulness accounted for 53.9% of the variability in behavioral intention, the measure of acceptance. Together, perceived usefulness, health care knowledge, and behavioral intention accounted for 68.5% of the variance in perceived effective use. Perceived ease of use and subjective norm indirectly influenced behavioral intention, through perceived usefulness. Perceived ease of use and subjective norm explained 48% of the total variance in perceived usefulness.
The study demonstrates that perceived usefulness, perceived ease of use, subjective norm, and healthcare knowledge together predict most of the variance in patients' acceptance and self-reported use of the web-based self-management technology.
随着个人健康记录和其他以患者为中心的健康技术的出现,人们越来越需要更好地了解促成这些创新接受和使用的因素。在这项研究中,我们采用统一技术接受和使用理论作为基础,以确定哪些因素可以预测患者对基于网络的互动自我管理创新的接受(通过行为意向来衡量)和感知有效使用。
对一项评估基于技术的家庭护理实践的随机现场研究数据进行的横断面二次分析,该研究针对患有慢性心脏疾病的成年人。
根据先前研究中经过验证的测量量表,设计了一份问卷,作为父母研究方案的一部分,用于衡量接受度结构。采用项目分组的潜在变量建模来评估患者的接受度。
感知有用性解释了行为意向(接受度的衡量标准)变化的 53.9%。感知有用性、医疗保健知识和行为意向共同解释了感知有效使用的 68.5%的变化。感知易用性和主观规范通过感知有用性间接影响行为意向。感知易用性和主观规范解释了感知有用性总方差的 48%。
该研究表明,感知有用性、感知易用性、主观规范和医疗保健知识共同预测了患者对基于网络的自我管理技术的接受程度和自我报告使用情况的大部分变化。
