The objective of this study was to report on the validation of new scales [called the Altarum Consumer Engagement (ACE) Measure] that are indicative of an individual's engagement in health and healthcare decisions. The instrument was created to broaden the scope of how engagement is measured and understood, and to update the concept of engagement to include modern information sources, such as online health resources and ratings of providers and patient health.
Data were collected through an online survey with a US population of 2079 participants. A combination of Principal Component Analysis (PCA) and detailed Rasch analyses were conducted to identify specific subscales of engagement. Results were compared to another commonly used survey instrument, and outcomes were compared for construct validity.
The PCA identified a four-factor structure composed of 21 items. The factors were named Commitment, Informed Choice, Navigation, and Ownership. Rasch analyses confirmed scale stability. Relevant outcomes were correlated in the expected direction, such as health status, lifestyle behaviors, medication adherence, and observed expected group differences.
This study confirmed the validity of the new ACE Measure and its utility in screening for and finding group differences in activities related to patient engagement and health consumerism, such as using provider comparison tools and asking about medical costs.
本研究的目的是报告新量表（称为阿尔塔鲁姆消费者参与度（ACE）测量量表）的验证情况，该量表可表明个体在健康及医疗决策中的参与度。创建该工具是为了拓宽对参与度的测量和理解范围，并更新参与度的概念，以纳入现代信息来源，如在线健康资源、医疗服务提供者评级和患者健康状况。
通过对2079名美国参与者进行在线调查收集数据。采用主成分分析（PCA）和详细的拉施分析相结合的方法来确定参与度的具体子量表。将结果与另一种常用的调查工具进行比较，并对结果进行结构效度比较。
主成分分析确定了一个由21个项目组成的四因素结构。这些因素分别命名为承诺、明智选择、导航和自主性。拉施分析证实了量表的稳定性。相关结果在预期方向上具有相关性，如健康状况、生活方式行为、药物依从性，并观察到预期的组间差异。
本研究证实了新的ACE测量量表的有效性及其在筛查和发现与患者参与度及健康消费主义相关活动中的组间差异方面的效用，如使用医疗服务提供者比较工具和询问医疗费用。
