Test-retest reliability of the End-User Computing Satisfaction instrument applied to representational model decision support systems

This article summarizes a test - retest reliability study of the End-User Computing Satisfaction instrument (EUCS). The instrument was distributed to real-world representational decision support system users through a mail survey. One month later follow-up surveys were mailed asking the original respondents to again evaluate the same system. The data sets were compared and suggest the instrument to be internally consistent and stable when applied to users of this particular information technology.
