心房颤动 (AF) 患者的经历涉及多种日常自我护理行为和持续自信地管理自己的病情。目前，还没有标准化的房颤患者信心自我报告测量方法。本研究的目的是为新开发的房颤信心管理措施的可靠性和有效性提供初步支持。本研究对房颤管理信心量表（CALM）进行了初步分析，该量表是为了衡量患者对房颤自我管理的信心而合理开发的。该量表通过患者教育平台以电子方式提供给 120 名 AF 患者样本（59% 男性）。采用主成分分析 (PCA) 和 Cronbach’s alpha 对测量的有效性和可靠性进行初步评估。 PCA 确定了一个四因素解决方案。 CALM 的内部一致性被认为非常出色，Cronbach 的 α = .910。额外的 PCA 证实了单因素解决方案的价值，可以产生总置信度评分，从而提高实用性并简化临床解释。测量患者对治疗房颤的信心的新型量表的初步评估提供了有希望的可靠性和有效性。患者对 AF 自我管理的信心可能被证明是有用的，可以作为患者体验超越生活质量的关键标志和终点。
The patient experience of atrial fibrillation (AF) involves several daily self-care behaviors and ongoing confidence to manage their condition. Currently, no standardized self-report measure of AF patient confidence exists. The purpose of this study is to provide preliminary support for the reliability and validity of a newly developed confidence in AF management measure. This study provides preliminary analysis of the Confidence in Atrial FibriLlation Management (CALM) scale, which was rationally developed to measure patient confidence related to self-management of AF. The scale was provided to a sample of AF patients N=120, (59% male) electronically through a patient education platform. Principle components analysis (PCA) and Cronbach’s alpha were employed to provide preliminary assessment of the validity and reliability of the measure. PCA identified a four-factor solution. Internal consistency of the CALM was considered excellent with Cronbach’s α = .910. Additional PCA confirmed the value of a single factor solution to produce a total confidence score for improved utility and ease of clinical interpretation. Initial assessment of a novel scale measuring patient confidence in managing AF provided promising reliability and validity. Patient confidence in self-management of AF may prove useful as a key marker and endpoint of the patient experience beyond QOL.
