An Abstract of Assessment of the Measurement Properties of the NHCAHPS Family Survey: A Rasch Scaling Approach by Matthew S. O’Connor Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in Foundations of Education The University of Toledo May 2013 The introduction of the Consumer Assessment of Healthcare Providers and Systems (CAHPS), a family of survey instruments designed to capture and report people’s experiences obtaining health care could soon add satisfaction as a consistent dimension of quality that skilled nursing facilities (SNFs) are required to assess and report. The SNF setting has not yet been mandated to implement CAHPS for Nursing Homes (NHCAHPS). Given the critical implications (e., comparisons of SNFs on NHCAHPS scores) and decisions resulting from performance on the NHCAHPS survey (i., Medicare reimbursement) it was imperative to construct a measure of family satisfaction.
The data were analyzed with the Rasch rating scale model. Rasch analyses demonstrate that the NHCAHPS Family Survey has adequate reliability, separation, fit, rating scale functioning, and dimensionality. Particular attention was given to the Overall Rating of Care item. According to the Rasch diagnostic indices, the NHCAHPS Family Survey composite domains did not function well.
Results are discussed in terms of their application to usefulness by SNF management teams for process improvement and to include in the Five-Star Quality Rating System. iii This dissertation is dedicated to my wife, Karen, and my children: Jason and Drew. Your tremendous patience and sacrifice as I pursued a lifelong dream will always be something I remember. I hope that one day Jason and Drew pick up this document and understand that when they have a dream they will need to work hard to accomplish it.
Working hard will mean giving up immediate gratification to achieve something more fulfilling. When I started on this doctoral journey, Jason was 5 and Karen was pregnant with Drew. This meant I had to leave Karen many evenings with 2 young boys as I attended class. She was able to make it through some tough times and will be happy this chapter of my life is now over.
I know it was not easy and I will always be thankful. There are many other people who were very helpful and supportive during this journey. My parents, Bill and Mary Pat, were always supportive of my dream. They helped me tremendously when this dream was derailed at one point in my life but knew it would be something I accomplished later.
My in-laws, Ron and Helen Payeff, took the boys many evenings when I was gone and helped to Karen out more than I will ever know during this time. Thank you for your support.
