This article describes the development and psychometric testing of the Patient Perceptions of Integrated Care (PPIC 2.1) survey, which we administered to 12,364 Medicare beneficiaries who received treatment from 150 randomly selected physician organizations, receiving 3,067 responses (26%). Psychometric analyses, performed using two methods to adjust for respondent inherent optimism (as a measure of response tendency), supported a 6-factor, 22-item model with excellent fit. These factors were (1) Staff Knowledge about the Patient's Medical History, (2) Provider Support for the Patient's Self-Directed Care, (3) Test Result Communication, (4) Provider Knowledge of the Patient, (5) Provider Support for Medication Adherence and Home Health Management, and (6) Specialist Knowledge about the Patient's Medical History. Per Spearman-Brown prophesy calculations, reliability would exceed 0.7 for all factors at 33 or more responses per organization. The PPIC 2.1 survey can distinguish six dimensions of integrated patient care with high physician organization-level reliability at reasonable sample sizes.
本文描述了患者对综合护理认知（PPIC 2.1）调查的开发和心理计量学测试，我们向 150 个随机选择的医生组织中的 12364 名医疗保险受益人发放了该调查，收到了 3067 份回复（26%）。使用两种方法对回复者固有的乐观主义（作为反应倾向的衡量标准）进行了心理计量学分析，支持了具有良好拟合度的 6 因素 22 项模型。这些因素是：（1）员工对患者病史的了解，（2）提供者对患者自我护理的支持，（3）测试结果沟通，（4）提供者对患者的了解，（5）提供者对药物依从性和家庭健康管理的支持，以及（6）专家对患者病史的了解。根据斯皮尔曼-布朗预言计算，如果每个组织的回复数达到 33 个或更多，则所有因素的可靠性都将超过 0.7。PPIC 2.1 调查可以区分综合患者护理的六个维度，在合理的样本量下具有高医生组织水平的可靠性。
