Main analysis
The data analysis to test the hypotheses was done by means of
structural equation modeling (SEM) using AMOS 20. In SEM, the
measurement model is a confirmatory factor analysis (CFA) model and the theoretical constructs are latent factors extracted from the
manifest variables. It is important to make sure that the measures
that were theoretically argued to be indicators of each construct
were acceptably uni-dimensional. The next step, then, in the study
was to perform a confirmatory factor analysis of HBM’s variables to
confirm the measurement scale properties. It is desirable that constructs
exhibit estimates of 0.50 or larger, because estimates less
than 0.50 indicate that variance due to measurement error is larger
than variance captured by the factor.
