Performance Improvement 2011-2012. Has the Redesign of an NIH Public Website Improved Its Usability, Usefulness, and Accessibility?

01/01/2012

This study evaluated the usability, usefulness, and accessibility of the redesigned National Institute on Deafness and Other Communication Disorders (NIDCD) public website. The website seeks to educate the general public and to provide communication disorder–related resources for scientists, educators, and health care professionals. 

The redesigned website enabled users to navigate quickly to the information they sought. The site scored higher than 80 in satisfaction in eight out of the twelve months a customer satisfaction survey was implemented. Scores for elements of satisfaction—content, functionality, look and feel—were consistently in the mid-to-upper 80's and low 90's, and no scores for the 12 month period were below 78. The Usability Compliance Rating comparing NIDCD's specific site pages against usability best practices, as gauged by the application of approximately 50 usability indicators, was 72%. The Usability Compliance Rating for the research landing page was 64%. Recommendations were presented to NIDCD to help improve the website's navigation and presentation.
