satisfaction toward ease of use, connection quality, and information quality reflects three
satisfaction indicators. An examination of the statistical properties of the scales in the survey
yielded a Cronbach’s alpha of 0.66 for SES and 0.48 for use amount. Considering the
recommended threshold range of 0.6-0.7, SES demonstrated weak but fair reliabilities for the use
amount variable. Reliability test for satisfaction indicated a Cronbach’s alpha of 0.72 for ease
of use, 0.76 for information quality, and 0.80 for connection quality, showing strong convergent
validity across satisfaction variables.
Structural equation modeling (SEM) was run on EQS 5.7b to perform a confirmatory
factor analysis (CFA) for the model of satisfaction measurement. This CFA tests the construct
validity of the factor loaded variables to the latent variables. Figure 2 illustrates the CFA model
with all factor loadings clearly indicating unidimensionality.
