<jats:p> In a survey of IS instruments spanning the years 1973 to 1988 (Zmud and Boynton [Zmud, R. W., A. C. Boynton. 1991. Survey measures and instruments in MIS inventory and appraisal. K. I. Kraemer, ed. The Information Systems Research Challenge Survey Research Methods, Vol. 3. Harvard Business School, Boston, 149–180.]), Doll and Torkzadeh's (Doll, W. J., G. Torkzadeh. 1988. The measurement of end-user computing satisfaction. MIS Quart. (June) 259–274.) 12-item End-User Computing Satisfaction instrument was reported as one of three IS instruments that met conditions to qualify as “well developed.” Recently, Etezadi-Amoli and Farhoomand (Etezadi-Amoli, J., A. F. Farhoomand. 1991. Issues and opinions on end-user computing satisfaction. MIS Quart. (March) 1–5.) questioned the validity of these measures. Part of their critique centered on the poor model fit obtained in a re-analysis using LISREL. While other potentially valid points were raised by Etezadi-Amoli and Farhoomand's critique, this report focuses only on their use of confirmatory factor analysis. In our re-analyses of Doll and Torkzadeh's original covariance measures, we show how model fit is extremely dependent on mod…
