Abstract

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.
