Evaluation of a User Information Satisfaction Short-Form Instrument.

摘要

The objectives of this thesis were to validate and evaluate the Baroudi and Orlikowski (2) short-form UIS instrument as a surrogate measurement of effectiveness of the Department of Defense's Composite Health Care System (CHCS). Hurd (1), using the short-form UIS instrument at the Naval Hospital Charleston, suggested that a fundamental change in the instrument's structure due to significant impact of contractor's services with the CHCS. The three Navy CHCS operational testing and evaluation hospitals were used in this study. The short-form UIS instrument was found to be inadequate for evaluation of overall UIS of the CHCS. Limitations found were: a fundamental change in the factor structure; unevenly distributed variables in a couple of factors; low reliability in one factor; no assessment of user interface with the system; and inconsistent convergent validity findings. A proposed re-design is presented. Statistically significant differences in UIS between groups and sites were found for the four factor solution. Participants were divided into three functional user groups: Physicians, Medical Support, and Administrative Support. All three groups were satisfied with the local Management Information Department staff and services and the system's output. All three groups were dissatisfied with the contractor services. Physicians were significantly less satisfied in three out of the four factors. No significant correlation between time of use of the system and UIS was found, except for the Administrative group's positive correlation with the system's output. UIS instrument validation; CHCS evaluation.
