Evaluating Health Service Delivery to Children With Chronic Conditions and Their Families: Development of a Refined Measure of Processes of Care (MPOC−20)

This article describes the development of a shorter and improved version of the 56-item Measure of Processes of Care (MPOC) to create MPOC−20. MPOC is a measure of parents' perceptions of the extent to which specific behaviors of health care professionals occur. MPOC−20 is a self-administered, parent-completed questionnaire that was derived from the original MPOC, using both conceptual and empirical approaches. Further refinements to MPOC−20 were made in its formatting and clarity of response options. MPOC−20 retains the same conceptual structure of five scales that reflect the essential features of family-centered service. We provide evidence of good internal consistency, reliability, and validity using pre-existing data sets and a new independent sample from a province-wide survey. MPOC−20 offers users a measurement option that is useful for program evaluation and quality assurance activities as well as for research purposes.
