ON THE REPEATED TEST-RETEST RELIABILITY OF THE END-USER COMPUTING SATISFACTION INSTRUMENT - A COMMENT

This comment extends the test-retest reliability of the end-user compu ting satisfaction (EUCS) instrument by Torkzadeh and Doll [10]. Wherea s Torkzadeh and Doll [10] reported stability for two hour and two week EUCS test-retest reliability, we investigate the test-retest reliabil ity of the EUCS instrument at two points in time, separated by a two y ear interval. We assess the end user computing satisfaction of persona l computer, as well as mainframe, administrative end users in a large public organization. The results of the repeated test-retest using dif fering application platforms add further support for the reliability o f the EUCS measure and highlight some areas of concern for managers of information systems.
